Transistors, the building blocks of modern electronics, are typically made of silicon. Because it’s a semiconductor, this material can control the flow of electricity in a circuit. But silicon has fundamental physical limits that restrict how compact and energy-efficient a transistor can be.

MIT researchers have now replaced silicon with a magnetic semiconductor, creating a magnetic transistor that could enable smaller, faster, and more energy-efficient circuits. The material’s magnetism strongly influences its electronic behavior, leading to more efficient control of the flow of electricity. 

The team used a novel magnetic material and an optimization process that reduces the material’s defects, which boosts the transistor’s performance.

The material’s unique magnetic properties also allow for transistors with built-in memory, which would simplify circuit design and unlock new applications for high-performance electronics.

“People have known about magnets for thousands of years, but there are very limited ways to incorporate magnetism into electronics. We have shown a new way to efficiently utilize magnetism that opens up a lot of possibilities for future applications and research,” says Chung-Tao Chou, an MIT graduate student in the departments of Electrical Engineering and Computer Science (EECS) and Physics, and co-lead author of a paper on this advance.

Chou is joined on the paper by co-lead author Eugene Park, a graduate student in the Department of Materials Science and Engineering (DMSE); Julian Klein, a DMSE research scientist; Josep Ingla-Aynes, a postdoc in the MIT Plasma Science and Fusion Center; Jagadeesh S. Moodera, a senior research scientist in the Department of Physics; and senior authors Frances Ross, TDK Professor in DMSE; and Luqiao Liu, an associate professor in EECS, and a member of the Research Laboratory of Electronics; as well as others at the University of Chemistry and Technology in Prague. The paper appears today in Physical Review Letters.

Overcoming the limits

In an electronic device, silicon semiconductor transistors act like tiny light switches that turn a circuit on and off, or amplify weak signals in a communication system. They do this using a small input voltage.

But a fundamental physical limit of silicon semiconductors prevents a transistor from operating below a certain voltage, which hinders its energy efficiency.

To make more efficient electronics, researchers have spent decades working toward magnetic transistors that utilize electron spin to control the flow of electricity. Electron spin is a fundamental property that enables electrons to behave like tiny magnets.

So far, scientists have mostly been limited to using certain magnetic materials. These lack the favorable electronic properties of semiconductors, constraining device performance.

“In this work, we combine magnetism and semiconductor physics to realize useful spintronic devices,” Liu says.

The researchers replace the silicon in the surface layer of a transistor with chromium sulfur bromide, a two-dimensional material that acts as a magnetic semiconductor.

Due to the material’s structure, researchers can switch between two magnetic states very cleanly. This makes it ideal for use in a transistor that smoothly switches between “on” and “off.”

“One of the biggest challenges we faced was finding the right material. We tried many other materials that didn’t work,” Chou says.

They discovered that changing these magnetic states modifies the material’s electronic properties, enabling low-energy operation. And unlike many other 2D materials, chromium sulfur bromide remains stable in air.

To make a transistor, the researchers pattern electrodes onto a silicon substrate, then carefully align and transfer the 2D material on top. They use tape to pick up a tiny piece of material, only a few tens of nanometers thick, and place it onto the substrate.

“A lot of researchers will use solvents or glue to do the transfer, but transistors require a very clean surface. We eliminate all those risks by simplifying this step,” Chou says.

Leveraging magnetism

This lack of contamination enables their device to outperform existing magnetic transistors. Most others can only create a weak magnetic effect, changing the flow of current by a few percent or less. Their new transistor can switch or amplify the electric current by a factor of 10.

They use an external magnetic field to change the magnetic state of the material, switching the transistor using significantly less energy than would usually be required.

The material also allows them to control the magnetic states with electric current. This is important because engineers cannot apply magnetic fields to individual transistors in an electronic device. They need to control each one electrically.

The material’s magnetic properties could also enable transistors with built-in memory, simplifying the design of logic or memory circuits.

A typical memory device has a magnetic cell to store information and a transistor to read it out. Their method can combine both into one magnetic transistor.

“Now, not only are transistors turning on and off, they are also remembering information. And because we can switch the transistor with greater magnitude, the signal is much stronger so we can read out the information faster, and in a much more reliable way,” Liu says.

Building on this demonstration, the researchers plan to further study the use of electrical current to control the device. They are also working to make their method scalable so they can fabricate arrays of transistors.

This research was supported, in part, by the Semiconductor Research Corporation, the U.S. Defense Advanced Research Projects Agency (DARPA), the U.S. National Science Foundation (NSF), the U.S. Department of Energy, the U.S. Army Research Office, and the Czech Ministry of Education, Youth, and Sports. The work was partially carried out at the MIT.nano facilities.

At the beginning of their first year, many MIT undergraduates choose to join one of the Institute’s 44 fraternities, sororities, or independent living groups (FSILGs), some of which are housed across Cambridge, Boston, and Brookline, Massachusetts.

There are 30 fraternities, nine sororities, and five independent living groups for students to choose from. Nearly 37 percent of undergrads join an FSILG, and these communities offer students more than a place to live, eat, and socialize; they are places where students create friendships, mentor younger students, work with both alumni and MIT administrators, raise funds for local charities, and learn valuable leadership skills.

While each organization has its own set of values, traditions, and membership process, they all share a common goal: creating communities where students can grow both personally and professionally inside and outside of the classroom, while navigating the rigors of an MIT education.

Anya Kattef ’98, director of FSILG Alumni Programs, says, “I can't imagine my MIT experience — or the decades that followed — without the extraordinary community I found in Alpha Phi. Surrounded by smart, compassionate, and driven women, I gained the confidence not only to survive MIT's demanding academic environment, but also to grow as a leader, progressing through the officer roles of athletic chair, house manager, and ultimately president. Beyond the leadership opportunities, the mentorship I received from upperclassmen helped me secure my first summer internship, navigate course selection, and pursue opportunities I might otherwise have overlooked. And perhaps most meaningfully, the friendships I formed through Alpha Phi while at MIT have grown into lifelong bonds that continue to shape and enrich my life.”

Service is a common bond

Liz Jason, associate dean and director of FSILGs at MIT, says “although every organization is unique and has its own personality, service remains a common thread throughout every fraternity and sorority. Many national organizations partner with causes ranging from heart health research and children's hospitals to literacy initiatives. Local chapters then build additional partnerships with organizations throughout Greater Boston, supporting causes such as Rosie's Place, the Boston Area Rape Crisis Center, animal welfare organizations, and other community nonprofits.”

FSILGs often host signature fundraising events tied to philanthropy, while others organize volunteer opportunities throughout the year, such as cleaning up Back Bay alleys, so that it’s woven into the members' experience.

Jason also notes: “Our culturally based fraternities and sororities place a particularly strong emphasis on community service, with some requiring prospective members to demonstrate volunteer work before joining. In addition, some of our national organizations require students to complete at least one semester of college before joining to ensure they have established academic success first.”

Leadership and responsibility

Presidents and leaders of an FSILG take on a large amount of responsibility that goes beyond the scope of organizing social events or fundraisers. They’re managing organizations that function much like a small business.

“Leaders learn soft skills overseeing budgets, coordinating recruitment, mentoring new members, organizing educational programming, and often spend 10 or more hours each week fulfilling leadership responsibilities,” says Jason. “Leaders also learn conflict resolution while navigating disagreements among members or neighboring residents. They practice delegation, budgeting, prioritization, and time management. They gain experience running meetings, communicating with alumni volunteers, and working with senior Institute leaders. They have a seat at the decision-making table. As a leader, if you expect your peers to do something, you need to model and espouse that behavior, too.”

For students living in chapter houses, the responsibilities can extend even further. Leaders learn to manage multimillion-dollar properties. Student leaders coordinate building maintenance, communicate with vendors, oversee safety inspections, organize chores, and help maintain properties that, in some cases, have housed MIT students for more than a century. The student house manager manages the facility, attends training four times a year, where FSILG leadership goes over seasonal items they need to know, such as removing snow from sidewalks and steps, liability insurance, and safety inspections.

As the chapter president of Pi Beta Phi, senior Tea Picconatto says, “My role as president has strengthened my communication, leadership, and conflict-resolution skills. It has also connected me to the broader national organization and provided opportunities to build relationships with members and alumnae across the country. From a professional perspective, the experience has been valuable in demonstrating leadership and responsibility to future employers. I’m certain I was hired for two of my internship roles because of my sorority leadership experience.”

Picconatto adds, “Greek life offers a unique sense of identity, community, and connection to a nationwide network of members and alumnae that continues well after graduation in a way that is not replicated elsewhere on campus. My sorority sisters have always been there to offer emotional support, academic guidance, and encouragement whenever I have needed it.”

At MIT, Alpha Delta Phi Society is a gender-inclusive member of the Institute’s Interfraternity Council. As president, Gabriel Tian, who came to MIT from Toronto, Ontario, sought a community with which to experience MIT. During the first week of school, he was studying at the ADPhi house library late at night and said it felt very natural and productive. He says he thought “this is where I belong,” and pledged shortly after. Tian quickly became involved as academic chair and vice president, and even helped update the chapter's website.

“I have learned so much since Rush — how to be a leader, how to make difficult decisions, how to have hard and personal conversations, how to run a living community with an executive board, how to socialize more effectively to connect with each and every member. Being the president, or any other leadership position, is tough, but so incredibly valuable, and gives me confidence in myself and my ability to care of my community,” says Tian.

“In just two years since joining, I have made lifelong friends. In fact, some of the closest friendships in my life are right here in the siblinghood. The web of connections my chapter offers really enables connections between people who otherwise would not have the opportunity to have even met at MIT. To me, ADP makes MIT all the more brilliant and special.”

After graduating

Long after graduation, many alumni continue volunteering with their chapters, serving on house corporations, mentoring students, and helping preserve traditions for future generations. For many, the relationships formed during college continue throughout their professional and personal lives.

Some families even span multiple generations of FSILG life, with parents and children joining the same FSILG years apart. Others have found lifelong friendships — or even spouses — through their chapter experience.

Cecilia Warpinski Stuopis ’90, the chief health officer at MIT Health, found that when she joined the Alpha Chi Omega sorority while a student, she had an “instant group of peers.”

“I was trying out for the volleyball team, and my teammate invited me to Rush to see what it was about. We both were invited to join. There were about 20 of us in our pledge class, and perhaps 40 women total in the sorority at the time, and I’m still friends with many of my Alpha Chi sisters to this day. We’re a very tight-knit group. Sororities are a very supportive network of people who care about each other.”

Stuopis, whose husband also graduated from MIT, adds, “I became reengaged with the community at MIT as an alum, as a volunteer, and then an advisory board member for Alpha Chi Omega. My daughter came to MIT and pledged Alpha Chi, too, and this allowed me to attend her initiation. I’ve been on the Board of the Association of Independent Living Groups at MIT for the last nine years and recently signed up for another three. At MIT, fraternities or sororities are not like they are portrayed in the movies. They are guided by friendships, developing bonds, and are there to support all aspects of their member’s success — both during their time as students and well into the future.”

In 2021, MIT set campus decarbonization goals as part of its Fast Forward climate action plan. Five years later, many of those goals have been met or are on track for completion, including efforts to make the Institute’s buildings more efficient, expand rooftop solar installations, and attain net-zero emissions. 

“Decarbonizing our campus goes hand-in-hand with MIT playing a leadership role in promoting carbon reduction and climate resilience through its research, innovation, and efforts to inform public policy in this area,” says Glen Shor, executive vice president and treasurer. “Our teams are leveraging that same innovative spirit to meet our campus climate goals.”

Creating an energy-efficient campus

Over the past decade, the Institute has decreased energy use per square foot by more than 10 percent, even as the campus has grown and research activity has intensified. Rooftop solar power generation has increased by more than five times in the same period, with installations added to the Stratton Student Center (Building W20), the Dewey Library (Building E53), the New Vassar undergraduate residence hall (Building W46), Graduate Junction (Buildings W87 and W88), and the theater arts building (Building W97). Thirty-three MIT building projects have earned Leadership in Energy and Environmental Design (LEED) certification. And in May, the Tina and Hamid Moghadam Building (Building 55) became MIT’s first Living Future Zero Carbon Certified building.

“We’ve completed more than 300 energy-efficiency projects across campus, focusing on our most energy-intensive research buildings, and ultimately touching nearly every corner of MIT,” notes Joe Higgins, vice president for campus services and stewardship.

Case in point: Building 46, home to the Brain and Cognitive Sciences Complex, and the Metropolitan Storage Warehouse (Building W41), newly home to the School of Architecture and Planning.

Building 46 was identified as one of MIT’s biggest energy users and the building with the greatest carbon-reduction potential. In 2024, the Institute completed a lab-by-lab renovation and improved Building 46’s mechanical systems infrastructure. The result: a 35 percent reduction in building energy use and carbon emissions — roughly a 2 percent reduction in overall campus emissions. 

The newly renovated Met Warehouse, which opened in August, features an innovative heat-recovery system, capturing heat rejected from the campus cooling system and using electric heat pumps to generate heat for the building. Higgins says the system will help inform the design of larger, campus-level heat-recovery systems.

Since 2014, 101 of the 168 buildings on MIT’s Main Campus have undergone energy-efficiency upgrades. The Institute’s 2030 Capital Plan will continue to invest in projects to reduce energy consumption and make efficiency upgrades a core element of all comprehensive building renewal projects. Examples of new projects include further optimizing heat-recovery systems; deploying more sophisticated controls to better manage ventilation, heating, and cooling; and using artificial intelligence to set classroom and office temperatures based on weather forecasts, occupancy patterns, and the forecasted carbon intensity of the regional power grid.

The renovation of Building 39, which is set to be home to a next-generation quantum research laboratory, will incorporate energy-saving features and technologies, including advanced insulation and windows, a smart ventilation system, LED lighting with automatic controls, and heat-recovery systems to maximize efficiency. These integrated systems are projected to dramatically reduce energy use and carbon emissions — cutting them by approximately 70–80 percent relative to the existing building baseline. 

Similarly, the McCormick Hall (Building W4) undergraduate residence hall renovation, which began this summer and is expected to be ready for students by the fall 2028 semester, will add high-performance windows, LED lighting, ventilation energy recovery, and low-flow plumbing fixtures. The project will replace gas cooktops with electric induction, use low-carbon flooring, improve stormwater management, and enhance the courtyard with native plantings, which require less water and maintenance while supporting local biodiversity.

On the path to net zero

MIT’s decarbonization efforts extend well beyond its campus. In recent years, the Institute has entered collaborations to create several large-scale renewable energy projects in regions of the United States where electric grids are still heavily reliant on fossil fuels. Together, these projects avoid over 200,000 tons of carbon dioxide per year, about equal to MIT’s annual direct campus emissions. 

“These projects, within a very short window of time, have had a significant impact on reducing emissions,” says Higgins. “They also put us on track to reach our net-zero target this year.” 

The first of these projects, the Summit Farms 60-megawatt solar farm in North Carolina, went online in 2016. Big Elm Solar in Texas, a 200 MW facility, followed in 2024, and Bowman Wind, a 208 MW wind farm in North Dakota, began operation in December 2025. Together, Big Elm and Bowman represent a landmark collaboration between MIT and 11 Massachusetts nonprofit and public sector organizations, including the City of Cambridge.  

“It’s a new market model that allows smaller organizations and government agencies to achieve greater reductions in carbon emissions that wouldn’t be possible on their own,” says Julie Newman, MIT director of sustainability. 

To capture the broader benefits of these projects, the Office of Sustainability worked with Institute researchers to develop a framework that assesses not only avoided emissions, but also economic and health outcomes. The team found that the projects generate economic benefits comparable to 7,000 one-year construction jobs and 189 maintenance jobs over 20 years. The projects’ annual health benefits are equivalent to 640 people quitting smoking for life, or nearly 200 premature deaths avoided each year for 20 years.

“Greener power sources are one of the building blocks we need to decarbonize our cities and campuses for the long run,” says Higgins. “That’s why we have made decarbonizing regional electricity grids a priority.”

The building blocks of campus decarbonization

To fully decarbonize MIT’s campus, the Institute will need to significantly change how it produces and distributes energy.

Currently, MIT’s Central Utilities Plant (CUP) burns natural gas to create electricity and steam-based heat, while also getting a small amount of electricity from the power grid. Electricity, heat, and air conditioning are distributed to campus buildings through a network of underground power lines and pipes. 

To move away from burning natural gas, and to take advantage of electricity from a greening grid for making heat, MIT is exploring creating a large-scale electric heat pump plant adjacent to the CUP on Vassar Street. The plant, a key building block for a long-term campus decarbonization strategy, will produce hot water and distribute it to campus buildings through a hot water-based heating system. 

“We’re starting the design process now, and in the coming year, we should know more about the scale and phasing of the heat pump plant we would construct, how it would interface with our existing district energy system, and the implementation timetable,” says Vasso Mathes, senior campus planner in the Office of Campus Planning, who is the campus decarbonization program manager. The heat pump plant will aim to recapture waste heat from existing cooling systems, supplying source energy to meet 30 to 40 percent of campus heating needs.

Another critical building block is transitioning MIT’s existing steam-based infrastructure to a hot-water system. That work — already underway — includes replacing steam distribution pipes to buildings with more efficient, easier-to-maintain hot-water pipes and converting buildings from steam to hot-water heat.

The third building block of a campus decarbonization strategy will be MIT’s ability to rely on the power grid for electricity instead of the CUP. “The electricity generated by the CUP is 15 to 20 percent lower in carbon emissions than the New England grid,” says Mathes. “We expect this to change over time as more and more renewables are added to the grid.” Even then, the CUP would be maintained as a backup system for use during peak heating and cooling days and grid stress events.

Finally, “the fourth building block is to go bigger, and look at shared infrastructure and coordinated planning with neighboring institutions and municipal partners,” says Higgins.

In that vein, earlier this year MIT became an anchor institution in the BosTEN Project, a year-long study to explore the feasibility of creating what could become the first city-scale thermal network in the United States. The network would help decrease the carbon footprints of major buildings across Boston and Cambridge, Massachusetts, by harnessing heat from the soil and rock under the Charles River and Boston Harbor, as well as waste heat from buildings and industrial facilities. It would also provide a renewable source of energy that can stabilize and even reduce the costs to heat and cool buildings.

“We’re thinking through how we can not only decarbonize our campus, but also how to use our work as a catalyst for broader strategies and technologies that others could readily employ,” Higgins says. “The unit of change needs to be at the city scale.”

For decades, one of the major complaints about nuclear power in the United States has been the argument that, after all this time, we still have not come up with a dependable strategy for sequestering high-level radioactive waste, including spent fuel from plant operation. This issue is of such importance that Haruko Wainwright has put it at the center of her research agenda as an Atlantic Richfield Career Development Professor in Energy Studies at MIT and an associate professor in the departments of Nuclear Science and Engineering and Civil and Environmental Engineering. 

In an essay called “The best-managed industrial waste in history,” which appeared in the Aug. 27 issue of the journal Nature, Wainwright made a bold statement, maintaining that an expansion of the nuclear power sector in the United States will benefit the environment, despite the fact that a solution to the permanent disposal of nuclear wastes has yet to be demonstrated in this country. 

In this interview, Wainwright describes risks associated with different forms of waste, ways to improve waste-handling procedures, and what lessons other countries can teach the U.S. in this realm.

Q: Why do you think chemical contaminants pose a greater public health risk than radioactive wastes?

A: I’ve always appreciated the fact that the dangers of radiation were recognized relatively early in the 20th century, prior to the widespread use of nuclear technologies. By the time an industry emerged, radiation protection standards were reasonably well established, including waste management. While nuclear power plants inevitably produce highly radioactive spent fuel, it is both solid and compact, making it relatively easy to contain and isolate from the environment. It took time to develop a disposal solution because people were pursuing a perfect one. Now, several countries are demonstrating that effective isolation over geological timescales is feasible. Finland, in fact, is about to open the world’s first deep geological repository for spent fuel.

Chemical contaminants present a different story. For many substances, like hexavalent chromium and PFAS (“forever chemicals”), the risks were identified long after they’d been released, having spread widely through the environment, food chains, and human bodies. PFAS, for example, has been used in industry and consumer products since the 1940s, yet the first federal drinking water standards were not adopted until 2024. Chemical hazardous wastes — including substances that degrade very slowly or not at all — are disposed of in the shallow subsurface without the requirement of long-term predictive assessments.

This is not to suggest that radioactive wastes are without risk. However, public perception is often disproportionately focused on — often hypothetical — nuclear hazards, while underestimating the dangers posed by chemical wastes. This misalignment actually has an adverse effect on the environment and public health. It leads to the misallocation of resources, diverting funding — including taxpayer dollars — away from worrisome contaminants whose environmental and public health consequences are already occurring. 

Q: How can we improve our procedures for storing spent fuel as more nuclear power plants come into operation around the world?

A: The nuclear industry is becoming increasingly proactive about waste management. Some companies, for example, now incorporate spent fuel storage capacity directly into their power plant designs, formulating plans that cover the entire operating period. Research on waste streams from advanced reactors — and even fusion reactors — is also growing. This approach of thinking about wastes before any are produced — what I call “design from the wastes up” — is critical for long-term sustainability.

Although further technical advances are surely needed, communication remains another area with significant room for improvement. Transparent monitoring programs and effective communications have been shown to build public confidence and provide assurance. Additionally, I believe we should place a greater focus on the inherent properties of radionuclides, including their risk pathways and mobility. Long-lived radionuclides are weakly radioactive and emit little or no penetrating radiation; their health risks are associated with ingestion or inhalation, analogous to chemical carcinogens. Most radionuclides, including plutonium, have low solubility and a high affinity for soil particles, limiting their mobility in the environment.

Current research on spent fuel storage has been devoted mainly to the integrity of the metal canisters used to contain spent fuel. Attention should also be directed toward developing predictive understanding of radionuclide transport and about geochemical barriers to the spread of radioactivity in the unlikely event of a containment breach. These approaches would exploit the natural immobility of radionuclides to afford additional layers of protection — in keeping with the nuclear industry’s recent embrace of passive safety features.

Q: How can the United States move toward the permanent disposal of nuclear wastes, and what can we learn from the European and Canadian examples? 

A: Many people tend to dwell on political and social issues, while the underlying science is frequently left out of the conversation. Fundamental questions — regarding the true dangers of radioactive materials and the feasibility of safe geological disposal — often go unanswered, leaving nuclear waste a vague, almost mythological threat, rather than a technical and engineering problem.

In fact, many people in geoscience believe that the failure of Yucca Mountain — the proposed geological repository for high-level radioactive wastes in the U.S. — stemmed from the fact that the site was chosen for political rather than scientific reasons. In 1987, Congress amended the Nuclear Waste Policy Act to confine site characterization to a single location, abandoning the original plan to screen multiple candidates. This top-down decision, widely dubbed the "Screw Nevada Bill," generated vehement local opposition. In addition, Yucca Mountain is the only proposed repository in the world situated above the groundwater table and within a zone of fractured igneous rock, where radionuclides are relatively mobile. Demonstrating its long-term safety is, consequently, much more difficult than for other proposed repositories.

Europe's approach to waste disposal offers a stark contrast. Switzerland, for example, identified a preferred site after a transparent, scientific evaluation of multiple candidates based on technical criteria, earning community acceptance as a result. Sweden and Finland built trust through decades of patient consultations with the public. And in Canada, more than 10 communities voluntarily expressed interest in hosting a repository before one favored site was ultimately selected.

Another underappreciated difference relates to how public concerns are handled. In the U.S., worries about radiation and radioactive waste have often been brushed aside by experts. In Europe, communication professionals and experts are trained to address every concern sincerely, offering understandable, science-based explanations. Discussing those concerns, moreover, can provide valuable opportunities to identify knowledge gaps and improve safety.

I believe that selecting a geologically sound site and communicating the science clearly — in terms that anyone can grasp — are the essential first steps toward achieving the permanent and safe disposal of nuclear waste.

Deep in the ocean, brown algae and diatoms produce a complex carbohydrate molecule called fucoidan, which helps form the algae's protective outer layer. The fucoidan molecule is very difficult for microbes to break down because its chemical structure may include dozens of different linkages and branching patterns that vary from one algae species to another. This resistance to decay is one reason why fucoidan matters; when microbes struggle to break it down, fucoidan can sink deep into the ocean, carrying carbon with it and potentially storing it for long periods. This could make fucoidan an important player in the ocean’s carbon cycle.

For many years, scientists knew of individual bacteria that could break down pieces of fucoidan. But one fundamental question remained unanswered: Could a microbial community break it down completely, and if so, how?

A new open-access study published in Nature, led by Andreas Sichert, a former MIT postdoc now at ETH Zurich, and Otto X. Cordero, associate professor of civil and environmental engineering at MIT, provides an answer.

"No single bacterium can finish the job," says Cordero. "Instead, fucoidan is degraded through teamwork. Different bacterial strains specialize in different parts of the molecule, and together, their combined efforts get the job done far more efficiently than any one organism could manage alone."

A puzzle with 453 pieces

In order to understand how fucoidan breaks down in nature, the research team enriched a fucoidan-degrading bacterial community from coastal seawater samples. What they found was staggering: more than 453 different genes, each responsible for making an enzyme that can act on fucoidan, spread across eight bacterial strains the researchers isolated. On their own, none of these strains could fully break down the molecule.

But when the researchers used a new, rapid mass-spectrometry method, they were able to observe how bacteria consumed individual sugar building blocks — and a clear pattern emerged. All of that genetic complexity could be reduced to two roles. Some bacterial strains specialized in degrading fucoidan's fucose-rich "backbone," while others specialized in removing its side branches, which contain less-common sugars such as xylose and galactose.

When strains playing both roles were combined, something noteworthy happened: degradation didn't simply add up. Instead, it became synergistic and exceeded what the bacteria's individual activities could predict. The more complementary the strains' preference for sugar were, the stronger the effect became. In some cases, the paired communities came close to completely degrading the complex polysaccharide.

"The breakdown of one of the ocean's most abundant carbon pools rests on a division of labor," says Cordero, "not between particular strains, but between functional roles."

Turning complexity into predictability

The most surprising result was that this division of labor made the system much more predictable than its underlying complexity indicated.

The researchers developed a simple model that sorted bacterial activity into two broad categories: fucose, and the rarer sugars found in fucoidan's side chains. They trained the model using data from small communities containing just one to three bacterial strains.

The simplified model was able to predict degradation in communities containing up to seven strains, and its predictions also generalized to nine structurally different fucoidans from other kinds of algae.

"A predictive understanding of a complex system need not come from characterizing each of its parts," adds Cordero, "but from finding the right simplification." The finding suggests that scientists may be able to predict how efficiently other complex, carbon-rich biological materials are broken down in nature, even when their exact chemistry and the enzymes involved are only partly understood.

The researchers also found that bacteria with complementary capabilities often occurred together in samples taken from the natural ocean, suggesting that the division of labor observed in the laboratory may also play a role in the ocean.

The consequences extend well beyond the field of microbiology. 

The researchers propose a concept they call "diversity-limited degradation," in which the absence of the right combination of complementary bacterial specialists allows fucoidan to persist for longer instead of being broken down. This concept may help explain why some algal carbon stays in the ocean for extended periods, contributing to long-term carbon storage.

For biotechnology, the takeaway is more straightforward. Instead of engineering a single "superbug" that can digest tough and complex biomass, a more promising approach may be to bring together teams of microbes that already specialize in complementary tasks. These teams could potentially be used to process brown algal biomass and other complex polysaccharides on a larger scale.

Looking ahead

The broader promise, though, may lie in the approach, rather than the molecule. If hundreds of uncharacterized enzymes can be reduced to two measurable traits, the same strategy might work for other biopolymers whose chemistry has so far resisted description — and, more generally, for predicting what microbial communities do. 

"Here was a system with hundreds of enzymes acting on a molecule we still can't fully describe, and it turned out to be far more tractable than anyone expected," says Cordero. "What we found is that there's a level of organization above the individual enzyme, corresponding to traits we can measure and plug into simple models that predict function from (genomic) composition. When biology looks intractable, it may be that we haven't found the right level of description yet."

One question the work leaves open is a fundamental one. Fucoidan is abundant, and has been for a very long time, so why has no bacterium evolved to eat it whole? The researchers suggest answers on two levels: constraints within sugar metabolism itself, and evolutionary dynamics in which complementary specialists are continually regenerated rather than merged into one.

"Really, this is a question about how life on Earth is organized," says Cordero. "Why are the biochemical functions that drive the planet's elemental cycles distributed across many organisms instead of concentrated in a few? Explaining that is, I think, one of the frontiers of the life sciences."

In addition to Cordero and Sichert, the research team included co-authors from ETH Zurich, the University of Vienna, and the Tata Institute of Fundamental Research.

The work was supported by Simons Foundation through the Principles of Microbial Ecosystems (PRIME) collaboration.

MIT researchers have developed a new technique that helps generative artificial intelligence models find solutions to high-stakes problems.

In these settings, a plausible answer is not enough: The output often must also satisfy nonnegotiable safety, physical, or task-specific requirements, known as hard constraints.

The researchers developed a method that helps generative models meet these strict requirements without sacrificing the quality of their outputs. 

The key to their technique is to give the model more freedom during the generation process and enforce hard constraints on the final output, rather than at every intermediate step. 

In experiments spanning robotics, control of physical processes, and computer vision, the new method consistently satisfied the required constraints while identifying better solutions than existing techniques. 

This adaptable, plug-and-play technique works at deployment time, so it can be applied to pretrained generative models without retraining them. It can make such models more useful in applications where safety rules, physical laws, or other strict requirements cannot be violated. 

“The promise of generative AI is its ability to explore a rich space of possibilities, but the real world places boundaries on which possibilities are acceptable. Our approach lets us preserve that generative power while enforcing the nonnegotiable requirements of high-stakes or safety-critical applications,” says Navid Azizan, the Alfred H. and Jean M. Hayes Career Development Associate Professor in the Department of Mechanical Engineering and the Institute for Data, Systems, and Society (IDSS), a principal investigator of the Laboratory for Information and Decision Systems (LIDS), and the senior author of a paper on this technique.

Azizan is joined on the paper by lead author Zeyang Li, a graduate student in mechanical engineering and LIDS; and Kaveh Alim, a graduate student in IDSS and LIDS. The research appears this week in the IEEE Transactions on Pattern Analysis and Machine Intelligence.

Freedom to explore

Pretrained generative AI models, such as diffusion models like Stable Diffusion and flow-matching models like FLUX, are now widely available. These powerful models learn to create new data by transforming random noise. Their availability has enabled people to adapt them to a wide range of applications.

These highly capable models excel at providing answers that come close to satisfying most queries, but in safety-critical applications like robot path planning on a crowded factory floor, an answer that is “nearly correct” may not be good enough. 

For instance, a “nearly correct” path from one machine to another might still result in the robot colliding with a human co-worker.

In such safety-critical applications, users often employ a technique called projection-based sampling, which repeatedly forces the model’s partial solutions, called intermediate samples, to satisfy strict requirements during the generation process.

But constraining the entire generation process can prevent the model from reaching a better final solution. These methods also typically focus only on satisfying the hard constraints, missing the opportunity to improve other qualities of the solution, like reducing the length of the robot’s trajectory.

“For constraint satisfaction, what ultimately matters is the model’s final output, since the internal process is discarded. By not requiring every intermediate step to satisfy the constraints, we give the model more freedom to find high-quality solutions that are still feasible in the end,” says Li. 

The researchers developed an algorithm called HardFlow that steers the sampling process so that the final output satisfies the user’s hard constraints without being overly restrictive and is of higher quality.

Subtle steering

HardFlow reformulates hard-constrained sampling as a trajectory-optimization problem, using tools from the field of optimal control. This enables the framework to steer the model’s sampling trajectory toward a goal, making subtle corrections along the way while enforcing hard constraints on the final output.

“Control theory gives us a powerful framework for formalizing the optimal way of making these corrections,” Azizan says.

But solving the trajectory-optimization problem around an enormous neural network was no easy task. The model may have hundreds of interconnected layers that process data.

To make the problem tractable, the researchers leveraged the structure of flow-matching models to decompose the problem into a sequence of smaller, single-step subproblems. They then applied systematic transformations and approximations to derive an efficient, scalable algorithm that still finds a feasible solution. 

“Essentially, we transformed the trajectory-optimization problem into something that preserves the key properties of the original problem, but can be solved very efficiently at deployment time,” Azizan adds.

Reformulating the task as an optimization problem allows HardFlow to incorporate additional goals that can improve the quality of the final answer. For instance, HardFlow could find a collision-free path for a robot that is also the shortest distance to its goal.

“Our framework can jointly handle both aspects, which helps it perform much better than existing methods,” says Li.

Across experiments in robotic manipulation, maze navigation, and text-guided image editing, HardFlow achieved perfect constraint satisfaction while consistently outperforming baseline methods on measures of solution quality. 

For example, it enabled a robotic manipulator to avoid collisions with obstacles while also finding the quickest path to the target object. Most other methods either resulted in collisions or found paths that took significantly more time.

In addition, HardFlow’s computation time was comparable to or lower than that of most competing methods.

In the future, the researchers could extend the framework to settings in which the AI model itself can also be updated, so that constraint satisfaction and sample quality can be improved in a more adaptive manner. 

The world needs more homes. The world also has too much plastic. Perhaps the only thing those two problems have in common is that they’re hard to solve.

Atlas Building Composites, a spinout of MIT, is on a mission to address both problems with a single solution. The company has developed an AI-powered robotic manufacturing platform capable of turning single-use plastics into durable building materials.

The company emerged from MIT HAUS, a research effort in the MIT Department of Mechanical Engineering that’s short for “Home Architecture for Universal Sustainability.” Atlas uses waterless plastic recycling and large-scale composite additive manufacturing technology to make parts like home foundations, decks, and trusses for walls, floors, and roofs.

“Our mission is to convert waste plastic pollution into durable composites to build 1 billion homes,” says Atlas chair and co-founder A.J. Perez ’13, MNG ’14, PhD ’23, who is also an MIT research scientist. “You can’t divorce these things from each other. We’re not here just to build homes, and we’re not here just to recycle plastic. The conventional way of building homes involves cutting down trees, mining, refining, and a bunch of other dirty activities. We want to avoid all that and address all the plastic bound for our oceans and landfills. We’re turning bottles into buildings.”

Atlas’ parts are already being used to support barns, sheds, decks, and docks. Most recently, the company supplied the U.S. Army Corps of Engineers with American-made recycled composite trusses to construct a 40-foot bridge in a Massachusetts wetland.

Perez and Atlas co-founder Matt Pouliot envision deploying thousands of their AI robotic production systems around the world. A key enabler for that scale is the company’s ability to recycle low-grade plastic into building components without water.

“This is key to democratizing recycling,” Perez says. “Now, every country around the world, regardless of their water access, will be able to do something about their plastic. We strive to study these issues in the real world, not just a lab. When you talk to government officials about creating a new recycling facility, they have to get the local water agency involved, there’s permitting, etc. A lot of that work disappears with the waterless recycling process.”

Research for impact

Since earning his PhD at MIT, Perez has been developing advanced fabrication techniques for homes and new techniques for plastic recycling. In 2019, he started MIT HAUS with David Hardt, MIT’s Ralph E. and Eloise F. Cross Professor in Manufacturing.

“It started with the simple mission of enabling the production of 1 billion homes over a 30-year period,” Perez says. “Then we realized how much the materials needed for those homes would strain global supply chains.”

Perez says building those homes using conventional methods would require a doubling of global production capacity for materials like concrete, not to mention a dramatic acceleration of global deforestation.

“That’s where the light bulb went off,” Perez says. “There’s this other problem humanity has, which is 8 gigatons of plastic that have been produced and are polluting our oceans, rivers, and cities. We decided to plug two really big, hairy problems together.”

Perez met Pouliot, a former Maine senator, and the pair started Atlas to commercialize the technology Perez had been developing at MIT. The founders worked with MIT’s Technology Licensing Office and have since worked with researchers at other universities to independently develop technology for the company’s robotic manufacturing platform, which the founders call the Atlas Factory Stack.

First, single-use plastic from water bottles and other objects is shredded and fed into the Atlas system, where it is melted and fused with American-made fiberglass to make it stronger than wood. From there, a large-scale 3D printer creates the parts, including trusses for floors, walls, roofs, and bridges.

Through research at MIT, Perez has shown large composite trusses can be printed in under 13 minutes and support over 4,000 pounds, exceeding key building standards.

“At MIT, we’ve demonstrated we can produce 60 to 80 pounds of parts per hour, and the systems we’re specifying in Atlas factories operate in the 150 to 200 pound per hour range,” Perez says. “There’s the potential for our robotic manufacturing platform to produce each part at a lower cost than injection molding, and it’s far more flexible and convenient. For example,  we can manufacture the parts in the reverse order so that they’ll be placed on the finished goods pallet next to the machine.”

The founders envision Atlas as a technology provider enabling the creation of home factories close to wherever homes need to be built. Today, each Atlas factory cell is capable of producing the structural framing components for about one small home per day.

“The old way of doing things would be some huge factory in China would mass produce one type of part and ship it far away,” Perez says. “I don’t think that’s good for the planet. Another reason we don’t use injection molding is economic: Mega factories don’t produce as many jobs and have a much higher carbon footprint. We want this to be localized to benefit local communities. The plastic is already everywhere. The more local Atlas is, the lower the cost and footprint.”

Going global

Plastics last far longer than wood, especially for applications where they’re in contact with the ground or water. That adds to the company’s environmental benefits.

“If you get a material into the building world and it does its job, it’s going to be used for a very long time and not need to be recycled again for a very long time,” Pouliot says. “That’s important because when you recycle something over and over again, it degrades. This is one of the most sustainable use cases for recycled petrochemical products.”

Atlas’ bridge with the Army Corps of Engineers was installed in less than a day. The founders are also in talks with international franchise partners to deploy the Atlas Factory Stack across the globe.

“To accomplish our mission, I fundamentally believe it’s not going to be one far-away company dominating the industry,” Perez says. “It’s going to be every country leveraging Atlas Factory Stacks to create local recycling jobs, local factory jobs, local construction jobs, and to stimulate their economies with local materials.”

The Federal Laboratory Consortium (FLC) selected AI-GUIDE, a medical device developed by MIT Lincoln Laboratory and Massachusetts General Hospital (MGH), for its 2026 Excellence in Technology Transfer Award. This award recognizes federal laboratories and collaborators who have accomplished outstanding work in the process of transferring technology. With funding from the U.S. Army's Combat Casualty Care Research Program (CCC), Lincoln Laboratory and MGH developed AI-GUIDE and are in the process of transferring the prototype to the startup company AutonomUS Medical Technologies, Inc.

"This recognition reflects what effective technology transfer looks like — aligning the Army's operational need with Mass General's clinical expertise and Lincoln Laboratory's engineering capabilities to deliver a solution with a clear path to impact. The transition to AutonomUS underscores how strong partnerships can carry a technology from development into real-world adoption," says Asha Rajagopal, Lincoln Laboratory's chief technology transfer officer. 

AI-GUIDE's transition to industry promises improved health outcomes for injured service members and civilians. Unlike ultrasound devices typically found in hospitals, AI-GUIDE is small and portable, making it ideal for use in pre-hospital settings. Pairing custom-developed AI software with commercial handheld ultrasound technology, AI-GUIDE helps the user insert a guidewire and catheter into a patient's blood vessel. This capability is especially important for U.S. military medics, who must keep injured soldiers alive in the field — sometimes for days — before they can be evacuated to a hospital. AI-GUIDE allows medics with minimal specialized training to administer medical interventions that would otherwise be impossible outside of the hospital, drastically improving patients’ chances of survival. 

The AI-GUIDE project has served as a framework for effective technology development and transfer. Within just three years, AI-GUIDE went from an idea proposed by CCC to a fully working proof-of-concept technology with its own startup company. Once the prototype was developed, clinical testing at MGH proved its viability, and Lincoln Laboratory and MGH staff then founded AutonomUS Medical Technologies to facilitate the commercialization process. With support from the MIT Technology Licensing Office, Lincoln Laboratory Technology Transfer Office, and CCC, the company secured U.S. Food and Drug Administration (FDA) Breakthrough Device Designation, a regulatory fast-track pathway that is only granted to highly innovative technologies with lifesaving potential, as well as a Small Business Innovation Research grant from the U.S. Department of the Air Force and funding from private investors, the Department of War, and the National Institutes of Health. 

These strong technology transfer collaborations are designed to streamline the transfer process, ensuring that lifesaving capabilities can be made available to military personnel and civilians as quickly as possible. While much of the initial work on vascular access has already been transferred, the AI-GUIDE team continues to develop and transition additional capabilities, including peripheral nerve block technology for trauma care and pain management. AI-GUIDE has previously been recognized with a Lincoln Laboratory Best Invention Award and an R&D 100 Award. 

"Lincoln Laboratory has a long record of transferring technology to industry. We are honored and proud to be recognized for the transfer of AI‑GUIDE and look forward to seeing the technology commercialized and saving lives in the field. This achievement reflects the strength of the partnership among the Defense Health Agency, Lincoln Laboratory, Massachusetts General Hospital, and AutonomUS Medical Technologies," says Samuel Kesner, a technical staff member in the Systems Engineering Group, who currently oversees the AI-GUIDE program at Lincoln Laboratory. 

Winning team members from the laboratory include Brian Telfer, Samuel Kesner, Lars Gjesteby, Joshua Werblin, Benjamin Roop, Alec Carruthers, Nancy DeLosa, and former Lincoln Laboratory staff members Matt Johnson (now the vice president of engineering at AutonomUS) and Laura Brattain (now an associate professor at the University of Central Florida). Asha Rajagopal, Jordan Mizerak, Melly Coronado, and Jonathan Dan supported technology transfer efforts.

This summer, the MIT Schwarzman College of Computing welcomed faculty from colleges and universities across Greater Boston, South Carolina, West Virginia, and Texas to campus for the inaugural AI Educators Pilot, a weeklong workshop aimed at expanding how artificial intelligence is taught across disciplines and learning environments. 

Inspired by MIT class C01/C51 (Modeling with Machine Learning), a course developed through the Common Ground for computing and AI education that focuses on helping students understand and apply foundational AI and machine learning concepts to problem-solving in their own disciplines, the workshop gave educators an opportunity to explore how its materials and teaching methods could be adapted for their classrooms. 

“The broader goal is to expand AI education to more students by investing in training for instructors,” says Dan Huttenlocher, dean of the MIT Schwarzman College of Computing and the Panasonic Professor of Electrical Engineering and Computer Science (EECS).

“We want to empower students to become critical thinkers about AI, not just users of the technology,” says Asu Ozdaglar, deputy dean of academics for the MIT Schwarzman College and department head of EECS.

A collaborative model for expanding AI education

Bringing the program to life required broad collaboration across the college, including support from leadership, staff, and contributions from more than half a dozen instructors in fields ranging from finance and computer science to sustainability. Together, they helped shape a workshop that paired core technical concepts with examples and teaching materials adaptable to a range of classroom settings.

“I have not seen an effort quite like it — this many dedicated instructors assembling materials of this richness, all to equip the educators who serve their students,” says Saurabh Amin, the Edmund K. Turner Professor in Civil Engineering and faculty director of the AI Educators Pilot. Amin is also co-director of the Operations Research Center, which is jointly housed within the MIT Schwarzman College of Computing and MIT Sloan School of Management.

With support provided by Jake and Robin Reynolds, the pilot brought together 19 participants in July from Allen University, Babson College, Brandeis University, Marshall University, the University of Massachusetts at Lowell, the University of North Texas, and Wentworth Institute of Technology. Working alongside MIT faculty and instructors, participants explored the pedagogy behind Modeling with Machine Learning through a mix of demos, videos, and exercises, and collaborated in hands-on activities focused on translating the course’s materials and methods to their own classrooms.

“This opportunity has been very timely because we are starting an AI and data science program in my department,” says Wenjin Zhou, assistant professor of computer science at UMass Lowell. “We’ve already been thinking about: How do we teach our next generation of computer scientists within the area of AI? How do we integrate AI in the teaching? I wanted to learn more about how other people are doing it, and especially answer the question: If AI can create tools for anyone now, what does a computer scientist do?”

Moving beyond the black box

When it comes to AI, Amin notes, there is no shortage of high-quality material. What is usually missing is context: Opportunities for instructors and students to connect AI concepts to specific disciplines, problems, and ways of thinking. Those connections are often built through dialogue and reasoning, rather than by presenting AI as a fixed set of ideas to be received. But instructor capacity remains one of the scarcest resources.

“What is scarce are educators prepared to teach AI as more than a fixed body of concepts and tools, to ground it in their own field, help students use it with judgment, and demystify it, so students do not just apply models but learn to question, adapt, and build with them,” explains Amin.

Shen Shen, an EECS lecturer and one of the workshop instructors, adds, “How do we make sure that machine learning is not just a black box, nor this magic piece of new technology? You can think of it as a tool, or a new framing to help you solve the problem in your specific domain.”

From pilot workshop to educator network

Participants ended the week by reflecting on which workshop materials and teaching approaches they planned to adapt for their disciplines and courses. Their feedback will help shape future iterations of the pilot and support the development of a broader network of educators committed to expanding AI education across diverse learning environments.

Weijie Pang, an assistant professor of computer science at the Wentworth Institute of Technology who attended the workshop, looks most forward to ongoing community building activities. “This is a really valuable opportunity to communicate with other faculty from different majors and areas. I can see what other universities are doing and what we can learn from each other,” she says.

“It's helpful to know that everybody within different disciplines at different universities is struggling with the same questions of how we can best serve our students as the technology is changing. Hopefully, we can set them up for success by being a little bit more forward and anticipatory of what the AI use is going to be,” says Dylan Cashman, an assistant professor of computer science at Brandeis University.

The brain cancer glioblastoma is one of the most aggressive and treatment-resistant cancers known to medicine, carrying a median survival of just 12-15 months, even with the best available care. Now, researchers at the MIT Media Lab have developed injectable nanoantennas, each about one-hundredth the width of human hair, that can be magnetically activated to create localized therapeutic electric fields that target and kill brain cancer cells without damaging healthy brain tissue.

“In laboratory and animal studies, this approach significantly reduced tumor growth and extended survival without detectable side effects, highlighting its potential as a precise and safe brain cancer therapy,” says Deblina Sarkar, associate professor and AT&T Career Development Chair at the MIT Media Lab and head of the Nano-Cybernetic Biotrek group.

The researchers named their technology “HITMAN” — short for highly-localized electric-field-induced tumor therapy using magnetically actuated nanoantennas. 

An open-access paper describing this technology published today in Science Advances.

To test HITMAN against the most clinically realistic version of this disease, the research team worked with tumor tissue obtained from patients diagnosed with aggressive and chemotherapy-resistant glioblastoma at Mayo Clinic. Using cells derived from this tissue in the laboratory, the researchers demonstrated that HITMAN eliminated 52.2 percent of these drug-resistant cancer cells — more than five times than that achieved by the standard chemotherapy drug temozolomide (TMZ) — while leaving healthy neurons and brain-supporting astrocytes unharmed.

The team then implanted those patient-derived tumor cells into the brains of mice to recreate the disease in a living system. In these orthotopic animal models — widely regarded as the gold standard for preclinical brain tumor research — HITMAN substantially inhibited tumor growth, extending median survival by more than 50 percent with no detectable toxicity to major organs or surrounding healthy tissue. 

The injectable nanoantennas can be activated wirelessly from outside the body, with the application of a low-frequency (no higher than 200 kHz, to prevent tissue-damaging heat) magnetic field that can penetrate the skull and brain tissue. The magnetic field actuates parts within the nanoantennas made of magnetostrictive material, creating stress and strain, which result in deformation of a piezoelectric film, producing localized electric fields.

Such localized electric fields were demonstrated to preferentially attack glioblastoma at the cellular level, disrupting the cells’ inherent bioelectric currents and fields, which regulate cellular function. Such disruption provoked a number of antitumor mechanisms, including protein unfolding, membrane damage, and endoplasmic reticulum stress, curtailing the production of a cell’s functional proteins. Such forms of cell dysfunction led to cell death. According to the researchers, cancer cells were selectively targeted over healthy cells due to their high proliferative rate, which elevates protein-folding demand, as well as their characteristic abnormalities in membrane composition and intracellular organelles.

Among a wide array of control experiments, the researchers also exposed glioblastoma cells to the nanoantennas without applying a magnetic field, as well as exposing the cancer cells to a magnetic field alone, confirming that the demonstrated effects were in fact due to the nanoantennas and their magnetic field activation. They also tested for side effects damaging to the animal models’ major organs — kidneys, liver, spleen, lungs, and heart — and detected none.

Also demonstrated by the research was a significant reduction in the number of cancer cell colonies formed after application of the nanoantennas, from 112-150 in the control groups to just 26 in the experimental group, indicating significant potential to reduce tumor recurrence and metastasis.

If translated to clinical use, the nanoantennas, whose size is approximately 150 nanometers, could be injected through the skull. Sarkar points out, however, that a technology developed previously in her lab could make their deployment even simpler.

In 2025, Sarkar and her colleagues created “circulatronics,” a technology that could allow devices like the HITMAN nanoantennas to be administered through an injection in a patient’s arm and to travel to a target region of the brain. In that previous work, the electronic devices were integrated with living cells so they would not be attacked by the body’s immune system and could easily cross the blood-brain barrier, as was demonstrated in pre-clinical studies. 

A glioblastoma diagnosis comes with formidable treatment challenges. Because this type of cancer is extremely infiltrative, complete tumor removal is difficult to achieve and can affect cognitive function. Also, the tumors often resist radiotherapy and chemotherapy, and immunotherapy is challenged by an immunosuppressive tumor environment. 

“The persistent failure of these therapies underscores the urgent need for novel approaches to target treatment-resistant glioblastoma cells,” the researchers write. “HITMAN offers a minimally invasive, spatially precise, and clinically translatable therapy for glioblastoma.”

Sarkar is joined on the paper by other members of her lab, including Monochura Saha, a former MIT postdoc; Ishaq Khan, a former MIT senior postdoc; Baju Joy, Shun Ying Chen, Hao-Tung Yang, Preet Patel, and Pengrui Zhang, all MIT graduate students; and Faheem Azeemi, an MIT undergraduate student.

During the day, waste products such as lactic acid and worn-out proteins build up in the brain. When we sleep at night, waves of cerebrospinal fluid (CSF) help to wash away this waste, keeping the brain healthy.

In a new study, MIT researchers have shown that they can strengthen these CSF waves through exposure to short bursts of a gentle, staticky sound known as “pink noise” during sleep. These bursts increase the amplitude of slow electrical waves in the brain, which then enlarges the CSF waves.

The researchers now hope to explore whether this enhanced CSF flow could help to boost cognitive function, improve memory, or even slow the progression of neurodegenerative diseases caused by the buildup of harmful proteins such as amyloid beta.

“We found that we were able to increase the size of the CSF flow wave during sleep, which as far as we know, there hasn’t been a method to do before. Now that we can enhance CSF flow during sleep in healthy adults, we’re really excited to bring this technology to clinical populations to see what effects we can have,” says Laura Lewis, the Athinoula A. Martinos Associate Professor of Electrical Engineering and Computer Science, a member of MIT’s Institute for Medical Engineering and Science and the Research Laboratory of Electronics, and an associate member of the Picower Institute for Learning and Memory. 

Lewis is the senior author of the study, which appears today in Science Translational Medicine. Joshua Levitt, who recently earned his PhD from Boston University and was a visiting graduate student in Lewis’ lab, is the paper’s lead author.

Cleaning up the brain

Cerebrospinal fluid is a clear liquid that surrounds and cushions the brain and spinal cord. In addition to protecting the brain from injury, it also helps provide nutrients such as glucose and removes waste products secreted by brain cells as they burn energy.

In 2019, Lewis reported a way to use functional magnetic resonance imaging (fMRI) to measure CSF waves as they flow in and out of the brain during sleep. That study showed that these waves are tightly coupled with brain waves called slow waves, which are associated with deep sleep.

In the new study, she wanted to further explore the relationship between brain waves and CSF flow, and investigate whether manipulating brain waves might enhance CSF flow. Previous work had already shown that delivering an auditory stimulus at the peak of slow waves can deepen the waves.

“You can make more of these electrical slow waves through an auditory stimulus, if it comes at just the right time. Similar to a child on a swing, if you push them when they’re at the right moment in their movement, you can make that swing go farther,” Lewis says. “The challenge is: How do you find just the right time?”

The auditory stimulus used for this study is a 50-millisecond burst of pink noise. Similar to white noise, pink noise contains all sound frequencies audible to the human ear, but the lower pitch frequencies are louder and the higher pitch frequencies are softer. This creates a balanced, gentle sound similar to steady rain or a distant waterfall.

To deliver these bursts at the peak of the brain’s slow waves, the researchers had to measure each participant’s EEG activity as they slept. This proved challenging because they also needed to measure fMRI signals to monitor CSF flow, and the magnetic fields used for fMRI interfere with EEG signals.

To overcome that, the researchers developed a way to process the EEG signals to eliminate the noise caused by fMRI, very rapidly — in less than 100 milliseconds. To make up for that small lag time in the EEG measurement, they also developed an algorithm that could predict when the slow wave peaks would occur. This allowed them to deliver the pink noise stimulus at the correct time.

More restorative sleep

In tests of 14 healthy volunteers, the researchers found that the auditory stimulus they delivered — which is not loud enough to wake a sleeping person — increased the amplitude of both the slow electrical waves and the CSF waves, during sleep.

Their fMRI studies also revealed that the slow waves stimulate blood vessels to constrict and dilate, allowing them to act as a pump that drives CSF out of the brain. Slow waves are seen only during non-REM sleep, and they become more prominent in deeper stages of sleep.

The researchers now hope to study whether enhancing CSF flow could help people to get more restorative sleep, especially people with insomnia. They also plan to explore whether increasing the flow of CSF, and the removal of waste products from the brain, could help people with Alzheimer’s and other diseases characterized by buildup of harmful proteins. 

“Brain waste clearance is really important for Alzheimer’s and other forms of dementia, which are caused, in part, by the buildup of molecules like amyloid and tau in the brain. If we can improve brain waste clearance, we may be able to help prevent the buildups of these plaques that lead to disease,” Levitt says.

Levitt has started a company that hopes to develop a device, such as a headband, that people could use at home to increase CSF flow by delivering an auditory stimulus at the right time. 

The research was funded by a McKnight Scholar Award, a Sloan Fellowship, a Pew Biomedical Scholars Award, the Simons Foundation Collaboration on Plasticity in the Aging Brain, the MIT EECS Transformative Research Fund, the National Institutes of Health, the Corundum Convergence Institute, and the Panasonic Well Fellowship for AI and Wellness.

As a liquid that is easily stored and transported, ammonia (NH3) is an attractive carrier for hydrogen, which is used in fuel cells, semiconductor manufacturing, chemical processing, and other applications. However, breaking ammonia into hydrogen and nitrogen typically requires high temperatures, and the resulting gas mixture must undergo additional purification before the hydrogen can be used in many applications. 

MIT researchers have now developed an electrochemical approach to promote hydrogen release from ammonia while simultaneously separating and concentrating the hydrogen into a high-purity stream. Their strategy, which uses electricity to speed up the extraction, reduces the temperature and energy required to recover hydrogen from ammonia and other hydrogen carriers.

In a new study, the researchers showed that their approach can generate highly concentrated, pure streams of hydrogen.

“We have shown the ability to use electrochemistry to drive thermodynamically uphill and kinetically difficult dehydrogenation reactions,” says Yogesh Surendranath, the Donner Professor of Science and a professor of chemistry and chemical engineering. “In this case, we studied the conversion of ammonia and a liquid organic molecule because of their importance as possible hydrogen carriers for a hydrogen economy. But the concepts we learned here could in principle be translated further, and we’re actively working on translating it to other important dehydrogenation reactions.”

Surendranath is the corresponding author of the study, which appears today in Nature. MIT postdoc Rui Zeng, now a professor of materials science and engineering at Harbin Institute of Technology in Shenzhen, China, is the paper’s lead author.

Extracting hydrogen

Hydrogen is widely used in semiconductor manufacturing and chemical processing and is also an energy carrier in fuel cells that use hydrogen and oxygen to generate electricity without combustion. Expanding its use, however, will require practical ways to store and distribute it.

Hydrogen gas itself is difficult to transport efficiently without compression or liquefaction. One alternative is to store hydrogen chemically in compounds that are liquids or can be readily liquefied, then release it where and when it is needed.

Ammonia is one promising hydrogen carrier because it is already produced and transported across large distances, but recovering hydrogen from ammonia remains challenging. That process, known as “cracking,” requires temperatures higher than 500 degrees Celsius to achieve high reaction rates and conversion. The hydrogen must then be separated from nitrogen and unreacted ammonia.

“We wanted to ask whether we could use electrical inputs to drive what would otherwise be an unfavorable dehydrogenation reaction, and simultaneously do it in a way that would separate the hydrogen from the hydrogen carrier, so that it would be very pure and could be used directly in a fuel cell or other application that requires a high purity hydrogen stream,” Surendranath says. 

The key element of the researchers’ new design is the coupling of a palladium-based separation membrane with a hydrogen-generating electrode through a molten hydroxide electrolyte. The separation membrane selectively transports hydrogen while preventing other components of the reaction mixture from passing through.

Using the new setup, ammonia is first dehydrogenated by a catalyst containing ruthenium and cesium. The hydrogen then reaches the separation membrane, whose opposite side is in contact with a molten hydroxide electrolyte. 

The electrochemical gradient across this membrane effectively creates a “vacuum” for hydrogen, providing a strong driving force for its transport across the membrane. It also converts the hydrogen into protons and electrons, which travel separately through the molten electrolyte and external circuit, respectively, before recombining at a second electrode to form hydrogen gas. 

Because the membrane selectively transports hydrogen, the system produces a concentrated stream of hydrogen gas without requiring a separate downstream purification process.

“Using this electrochemical process, we’re able to do this active pumping of hydrogen from a low concentration to a high concentration,” Surendranath says.

Continuously extracting hydrogen can also help drive the dehydrogenation reaction forward, especially when the presence of hydrogen inhibits the reaction. In this way, this strategy does more than separate the product: It changes the reaction environment and enables hydrogen recovery under milder conditions.

This process thus can be performed at temperatures around 200 or 300 degrees Celsius, much lower than those required for conventional ammonia cracking. Another advantage is that it creates a pure stream of hydrogen that doesn’t need to be purified later on — a step that requires additional energy.

Curtis Berlinguette, a professor of chemistry and chemical and biological engineering at the University of British Columbia, described the method as “a powerful new way” to solve the problem of obtaining a pure stream of hydrogen from ammonia and other hydrogen carriers. 

“By using electricity to pull hydrogen through the membrane as it is released, they accelerate the dehydrogenation of ammonia and liquid organic hydrogen carriers while simultaneously producing a purified hydrogen stream. This is an important advance for the energy sciences because it opens a credible pathway for transporting hydrogen in stable chemical carriers and releasing it where and when it is needed,” says Berlinguette, who was not involved in the research.

Powering transportation

In this study, the researchers showed that this approach could be used to dehydrogenate not only ammonia but also methylcyclohexane. This molecule is part of a class known as liquid organic hydrogen carriers (LOHCs), which also hold potential as an energy carrier.

The researchers envision that their new strategy could be useful for transportation applications, such as powering cars, buses, or ships, or for fabricating semiconductors or electronics. Pure hydrogen gas is used for several steps in semiconductor manufacturing, where it plays important roles in boosting manufacturing yields and reducing surface defects.

Because palladium is an expensive metal, the researchers are now working on ways to reduce the amount of palladium needed for the separation membrane. They are also working on scaling up the process, and on applying it to other dehydrogenation reactions that could be industrially useful.

The research was funded by the U.S. National Science Foundation.

How will global access to food, water, and energy evolve in coming decades? A new study co-authored by MIT researchers suggests the answers could be very different depending on region, resource, and income.

Based on extensive modeling of many different resource scenarios, the study finds that in some regions, lower-income people could be spending roughly 50 percent of their income on food by the year 2050, in contrast to higher-income groups that could spent about 5 percent of income on food in the same areas. 

“For a lot of these outcomes, the lower-income groups see much worse potential insecurity,” says Jennifer Morris, a principal research scientist at the MIT Center for Sustainability Science and Strategy and the MIT Energy Initiative, and co-author of a new paper detailing the findings. The results, she notes, can be evaluated by policymakers in different global regions to understand what the long-term, large-scale resource security risks may become for different parts of their populations. 

“Anything that’s taking up half of your income is potentially destabilizing for your entire life because it leaves so few resources for the other critical needs and basic life necessities,” Morris says. 

The study focuses on projecting future access to food, water, and energy, based on long-term variation across a dozen major factors influencing their availability, from economic conditions and agriculture production to trade conditions, climate, land use, and more. 

“This study shows that there is no single driver of future food, energy, and water insecurity,” says Gi Joo Kim, a research scientist at Tulane University and co-author of the paper. “Income is important, but regional conditions, land use, energy systems, water availability, and consumer behavior all shape the risks people face.” For policymakers, he adds, “This means they need to consider specific combinations of factors that create vulnerability in each region.”

The paper, “Identifying Key Uncertainties and Drivers of Future Resource Security Outcomes Through a Multisector Scenario Ensemble,” appears in the journal Earth’s Future.

In addition to Morris and Kim, the authors include Brian O’Neill, an earth scientist at the Pacific Northwest National Laboratory; Marshall Wise, a system engineer at the Pacific Northwest National Laboratory; John Weyant, a professor of management science and engineering at Stanford University; and Jonathan Lamontagne, an associate professor of civil and environmental engineering at Tufts University. 

Filling a gap

The current study fills a gap in modeling among scientists studying issues such as long-term resource security. Given the complications of long-term analyses, many studies have used what scientists term “shared socioeconomic pathway” circumstances, a small set of senarios spanning broad global narratives about the future, rather than exploring specific outcomes such as how long-term resource access may shift in linked fashion across income groups in different regions of the world. Two years ago, the same group of authors wrote a paper calling for more socioeconomically specific scenario analysis focused on outcomes for human well-being; the current study is their effort to develop that kind of modeling. 

“For this type of study, where we’re focused on human well-being outcomes, the income piece is really important,” Morris says. 

To conduct the study, the researchers adopted an existing framework in the field, the Global Change Analysis Model (GCAM) version 7.1, which represents interactions between energy, economies, water, land, and climate while dividing the world into 32 regions, 235 water basins, and 384 land-use regions and making adjustments for things like estimated commodity prices over time.

The research group used 12 main variables connected to resource availability, including population, GDP, income distribution, carbon intensity, land use, agricultural trade, multiple energy consumption scenarios, multiple water-use projections, and more. They ran simulations for 3,735 different scenarios involving these factors, to better understand the range of possible resource outcomes by 2050. 

Broadly, the modeling does uncover some significant regional variations. In 2050 food security may be most acute in parts of sub-Saharan Africa, while energy security could be most acute for low-income residents in some parts of Asia, Eastern Europe, and the Middle East. 

But within any region, there may still be substantial variation in resource security. In southern Africa, the modeling suggests that the poorest 10 percent of the population by income could be spending 49.6 percent of its income on food, compared to just 5.5 percent for the wealthiest 10 percent of the population. In West and East Africa the projected food burden for the bottom 10 percent of the population in terms of income is projected to be 48.4 percent and 42.5 percent, respectively. 

To understand the potential change this represents over time, the researchers compared the results to data from the year 2015 in the GCAM model. For the lowest-income group across western Africa in 2015, the average food burden was about 25 percent of people’s income, compared to estimates for 2050 that range from about 20 percent to 75 percent of income. In southern Africa, the lowest-income group spent about 20 percent of their income on food in 2015, but the scholars’ modeling projects an increase in food burden ranging from 25 percent to 65 percent of income. The wide variation in projected burden reflects the wide range in possible future scenarios.

When it comes to energy, variation by income is also apparent. In some parts of the Middle East, for instance, the residential energy burden in 2050 is estimated to be just 1.7 percent for the highest income bracket but 18.9 for the lowest income bracket; in Eastern Europe, the energy burden reaches 11.3 percent of income for the lowest-income bracket, while resting at under 5 percent for the highest-income bracket. 

“Regional averages can make future resource-security risks appear more manageable than they actually are,” Kim says. “This means analyses that stop at the average may miss exactly the populations most vulnerable to future change.”

Understanding the dynamics

To be sure, as the scholars emphasize, there are many uncertainties when it comes to resource access, and uncertainty is always part of modeling the global economy and resources. Still, they believe these kinds of projections can provide a more detailed outlook about social conditions in 2050 than has previously been available.

“At the very least, it’s highlighting areas of concern and showing that they differ in different parts of the world,” Morris says. “One of the outputs of this type of study is to map that out and provide that kind of insight. That can also inform the focus of further studies into specific regions and concerns.”

The researchers also believe the results will provide a new roadmap for policymakers who may be concerned about long-term resource provision across the entirety of their societies. While having new projections is valuable, modeling also helps analysts and policymakers see which factors most clearly influence future resource outcomes, as well.

“Our method was designed to identify the conditions that produce different resource security outcomes, rather than to predict one most likely future,” Kim says. 

“It’s a different approach to scenarios than we typically see,” Morris adds. “The approach and method have been appealing to people because they have a broad range of uses and applications.”

The research was supported, in part, by the U.S. Department of Energy; Stanford University; and the National Research Foundation of Korea. 

Beneath the Arctic Ocean is an orchestra featuring natural and human composers, from cracking sea ice and whistling beluga whales to humming shipping-vessel engines. Researchers from MIT Lincoln Laboratory heard some of this cacophony when analyzing data from commercial off-the-shelf sensors that they integrated and deployed in 2024 during the U.S. Navy's Operation Ice Camp (OIC). This past March, during OIC 2026, the researchers returned to the Arctic with a higher-fidelity version of one of the sensors, a geophone, which detects vibrations in the sea ice.

"We're interested in things that make sound underneath the ice," says Ben Evans, a researcher in the laboratory's Advanced Undersea Systems and Technology Group. "For example, our OIC 2024 data contained marine-mammal songs. We need a better understanding of how such signals propagate through ice, and how to distinguish these signals from other sources."

This underwater soundscape is shifting as sheets of Arctic sea ice rapidly break and melt, opening previously impassable maritime routes for military and commercial activity. Determining the unique sound profiles, or acoustic signatures, produced by fracturing ice will enable researchers to develop predictive capabilities for building coastal community resilience, informing geopolitical strategy, and surveilling adversary Arctic activity. The Fiscal Year 2027 Administration R&D Budget Priorities and Cross-Cutting Actions calls for agencies to "prioritize research and associated research infrastructure investments that enhance America's ability to observe, understand, and predict the physical, biological, geologic, and socioeconomic processes and interacting systems of the Arctic to protect and advance American interests and ensure prosperity of America's Arctic residents," and to "invest in R&D that assures America's uncontested navigation and strategic utilization of the Arctic."

Weather woes

Evans and David Whelihan have been trekking to OIC since 2022, advancing their vision to distribute a set of low-cost sensors across the Arctic for continuous monitoring. Hosted by the Navy's Arctic Submarine Laboratory (ASL) every two years, OIC is a three-week event during which U.S. and allied military forces conduct operational readiness exercises. The temporary infrastructure ASL sets up for OIC — a drifting sheet of Arctic sea ice, atop which sits a runway and insulated tents for lodging and command and control — simultaneously enables researchers to test prototype equipment and conduct experiments in an environment otherwise inhospitable to humans. This opportunity is particularly valuable as Arctic monitoring systems are developed in support of U.S. Department of War priorities.

This year proved especially challenging, with back-to-back blizzards creating whiteout conditions. Temperatures persistently plunged to minus 25 degrees Fahrenheit, and winds blew at 25 to 30 miles per hour with 40 mph gusts. Although the team, which also included Ella Wawrzynek and Ryan Saenger, had intended on completing two stints on the ice — one to deploy the sensors and the other to retrieve them after a few weeks — the weather had other plans. Their initial trip to camp was delayed by a week as windblown snow halted all inbound and outbound flights.

While they waited in Prudhoe Bay, Alaska, for the weather to clear, Whelihan was readying another technology they planned to test at OIC: a modem from industry partner Havguard, a Norwegian defense technology startup, that can communicate through ice using magnetic fields (instead of radio-frequency signals, which are rapidly diminished by seawater). However, harsh conditions inside and outside in Prudhoe Bay led to some system failures, and he flew back to the laboratory to fix them. "De-risking and operationalizing critical technology for the warfighter is an important part of what we do," Whelihan says.

After Evans, Wawrzynek, and Saenger arrived at camp on March 7, not a single flight came or left for the next five days. During a "normal" mobilization at OIC, six to nine flights per day are typical. "At times, we couldn't see participating countries' flags on poles roughly 100 feet away from the command tent," Evans says. "We had to put on hats and sometimes goggles just to go between tents, whereas at previous OIC events we walked around with long johns and pants."

The day after their arrival, they loaded their sensors onto a sled, and a field party leader (an expert in Arctic survival) driving a 4x4 vehicle with tracks towed them outside the main camp area. After deploying a quarter of the sensors they had planned, their leader received a call from camp command instructing them to return. The windblown snow was picking up, and they soon wouldn't be able to retrace their tracks back to camp.

A week later, the team had a clear day to retrieve their sensors and fly out of camp. "We laughed, because we could very easily see camp from where we had deployed the sensors," Evans adds.

Magnetic communication

As Whelihan returned to Prudhoe Bay with the fixed communications modem, another blizzard hit. Because the laboratory team had already been to camp once and other research teams needed an opportunity to go onto the ice during the next clear-weather window, the laboratory contracted with UIC Science to conduct the modem experiment. A business unit of the Ukpeaġvik Iñupiat Corp., UIC Science provides logistical and technical support for Arctic research based in Utqiaġvik (Barrow), Alaska, the northernmost U.S. city. Unlike the drifting ice in the open ocean, the ice in Utqiaġvik is primarily landfast, meaning it's fastened, or anchored, to the shoreline or seafloor.

Through UIC Science, Whelihan and Wawrzynek learned how to ride snowmobiles and then drove onto a big lagoon, where they drilled a 2x3-foot hole through 3.6 feet of ice to deploy a remotely operated vehicle (ROV) carrying the Havguard communications modem. The modem is based on a magneto-inductive transmitter (positioned below the ice) and receiver (sitting atop the ice), which are housed within polycarbonate domes to protect the sensitive electronics. The duo had met with Havguard in Norway in fall 2025 to discuss plans for testing the modem in the Arctic, and Havguard in turn built a version to testing specifications. Prior to OIC, Havguard and the laboratory team deployed the modem on a large reservoir in Vermont. While not representative of Arctic sea ice over salt water, this environment allowed them to test their procedures and capabilities.

"Under the Arctic lagoon ice, we placed the ROV, which was also equipped with a Doppler velocity logger, a four-beam sonar system that measures the vehicle's speed and direction," Whelihan says. "We used those measurements as the ROV drove under the ice, plus aerial drone images, to superimpose a picture of the ROV on the site so we could track it and calculate the modem's rate of test-data transfer. We achieved through-ice communication at about 1.2 kilobytes per second on an alpha prototype system that had traveled from Boston to Alaska three times. This result is very encouraging, and the system warrants further development."

In future iterations of this setup, the data could then be relayed out of the Arctic through drones or satellites.

Community connections

While in Utqiaġvik for a week in mid-April, they participated over the weekend in the Piuraaġiaqta annual spring festival, watching a harpoon-throwing contest and proctoring a kids' snowmobile race. And with eighth graders at the local middle school, they discussed their Arctic R&D and engaged them in a game teaching sonar concepts.

"When you embrace this culture of community, you meet lots of interesting people and doors open up," Whelihan says.  

"Connecting with the Arctic community is an important aspect of our work," Evans adds. "Every time we come here, we cross paths with someone we don't expect to, learn about their work, and think about how we may be able to collaborate." For example, at OIC 2024, the laboratory team had met a professor from the University of Maryland at College Park with extensive experience collecting and analyzing cryoseismological data; they now hope to work with him to apply machine learning to discriminate between icequakes and marine mammal vocalizations.

In the lead-up to OIC 2028, the team plans to design, prototype, and test air-droppable versions of some of their sensors while continuing to partner with Havguard on the through-ice communications modem. Their next step is to optimize the modem's packaging to facilitate deployability in the Arctic and integration with the laboratory's sensor suite.

"The through-line in all this work is minimizing boots on the ice," Whelihan says. "Especially this year, we learned that the weather is in charge of our access to the Arctic. We need ways to easily get sensors where we want them and to retrieve the data they collect, even in these extremely challenging conditions."

This work is funded through the laboratory's internally administered R&D portfolio in mission-critical technology (integrated systems area) and the laboratory's Advanced Concept Committee, which funds high-risk, high-reward early-stage research addressing critical gaps in national security technology.

Massachusetts Governor Maura Healey and MIT President Sally Kornbluth will kick off MIT Future Fest, a new annual festival exploring the future of science, technology, art, and design, with “The Future Begins Here” panel, a celebration of Massachusetts innovation, talent and the bold questions shaping what comes next. The event will take place on Wednesday, September 30 at 3:30 PM at MIT’s Kresge Auditorium.

Curated and produced by the MIT Museum, the inaugural MIT Future Fest will take place across MIT’s campus from September 30–October 4, 2026. Governor Healy and President Kornbluth will be joined on the opening panel by Moderna co-founder and Flagship Pioneering founder and CEO Noubar Afeyan, MIT professor and entrepreneur Sangeeta Bhatia, and Bob Mumgaard, CEO and Co-Founder of Commonwealth Fusion Systems. Economic Development Secretary Eric Paley will moderate the discussion, which will explore how public, private, and educational institutions can work together to sustain talent pipelines, turn discovery into impact, and build the future

“Massachusetts is where the future is being invented, and MIT Future Fest is a chance to showcase our leadership in technology and design to the world,” said Governor Maura Healey. “From AI and robotics to clean energy and life sciences, the breakthroughs happening here are changing how we live and work. As Governor, I want Massachusetts to be the place where the best minds from around the world come to study, conduct research, start companies and scale their ideas. Our administration is investing in the talent, research and partnerships that make that possible, and we’re proud to launch MIT Future Fest with MIT.”

The following press release was issued Sept. 1 by the Broad Institute of MIT and Harvard.

In recent years, scientists have built methods to measure a cell’s transcriptome, or all the RNA produced by a cell, to study the cell’s identity and genetic activity. However, these methods rely on killing the cell to access the bits of RNA within, and offer only a one-time snapshot. 

Now, researchers at the Broad Institute and at MIT have invented a “cellular self-reporting” approach to make living cells share their own transcriptomes, so that scientists can analyze them without killing the cells. Described in Cell, the live cell transcriptomic method relies on virus-like particles, which the cells use to package and deliver RNA to the culture medium they’re bathed in. Scientists can simply sample the medium to isolate the RNA, and do this repeatedly to reveal how gene activity in the same cell population changes as the cells mature or respond to perturbations. The researchers applied their method to a variety of cellular model systems, demonstrating its potential to help reveal how cells go awry over time in disease and how drugs affect cells. 

“Our lab focuses our time and resources on developing tools that will actually get used and make real impact on the broader field,” says study senior author Paul Blainey, who is a core member of the Broad and a professor of biological engineering at MIT. “It’s so gratifying to see a real coming to fruition of this concept, which was complete science fiction when we started. It’s a great example of the innovative impact long-term high-risk, high-reward research can have.”

A cellular special delivery

The effort to build the new method began more than a decade ago, when the Blainey lab set out to find a new way to do RNA sequencing without killing cells. “The existing methods were a bit medieval and involved stabbing cells or cutting pieces off of them,” recalls Blainey. Inspired by the performance of molecular technologies such as CRISPR-based technology and their ease of adoption, Blainey and study first author Jacob Borrajo committed to developing a molecular method, which they knew would be challenging and take time, but would also make the approach scalable and easy for other labs to perform. 

The team found inspiration in retroviruses, which over millions of years evolved the ability to package their RNA genomes in protein shells to spread from one infected cell to another. To build their method, the team engineered mammalian cells to express a retroviral structural protein that can encapsulate not only viral RNA but also a cell’s RNA. Integrated into the cell’s membrane, the viral protein is able to recruit cellular RNA, form a shell around it to create a virus-like particle, and bud off from the membrane to enter the liquid medium around the cell. The scientists then take a sample of the medium, isolate the RNA, and sequence it to get a view of the transcriptome from that cell population — all without destroying or damaging the cells.

“Compared to methods using robotics or mechanical biopsies of cells, our molecularly encoded solution could be much more broadly enabling for the average life science or biomedical lab, particularly the time dynamic questions that we hope to elucidate with this technology,” says co-first author Mohamad Najia, research fellow in the Blainey lab and the lab of George Daley at Boston Children’s Hospital. Najia and Borrajo led the work along with co-first author Anna Le, a postdoc in the Blainey lab. 

Message in a bottle

To test the method’s broad applicability, the researchers showed that it worked in immortalized human cells, in cancer cell lines, in stem cells and neuronal cells made from them, and in primary cells from human donors. They also tested a culture of two human cell types growing together, using tags on the virus-like particles so that the signals from the two cell types could be distinguished during analysis. 

In addition, cellular self-reporting is useful for studying systems with crucial three-dimensional structures that researchers would rather not disturb. The team demonstrated their method on spheroids of human endothelial cells, capturing short-term transcriptional changes after biochemically stimulating the cells. 

They also collaborated with Linda Griffith, a professor of biological and mechanical engineering at MIT, to apply their method to her lab’s organ-on-a-chip devices. These models mimic the physiology of organs and can help minimize preclinical or animal model testing, but their complexity makes retrieving cells from the devices for analysis difficult. With cellular self-reporting, the researchers monitored gene expression dynamics in endothelial cells within the devices over time, revealing changes in genes related to how tissues form vascular networks that depended upon the source of supporting fibroblasts, such as from either uterus or lung. 

The Broad team is continuing to look for new applications and biological questions to ask with their system, and are working to make the approach feasible for studying single cells. For now, they hope that scientists interested in following how cells and tissues change over time will give their method a try.

For generations, the steel mills of Southeast Chicago offered work and a way of life, experienced by tens of thousands of families. Open around the clock, three shifts per day, the vast works of U.S. Steel, Republic Steel, Inland Steel, and many others provided demanding but steady jobs, while making materials to build the country. 

Professor Christine Walley, head of the MIT Anthropology program, grew up in the area, where her father worked for Wisconsin Steel. Over time, U.S. manufacturing downsized — her father’s plant closed in 1980 — and the mills left Chicago. Walley’s 2013 book, “Exit Zero: Family and Class in Postindustrial Chicago,” chronicles the economic and psychological toll plant closures took on the area’s workers and families. The book was followed by a documentary, “Exit Zero,” directed by Chris Boebel, media development director at MIT Open Learning (and Walley’s husband).

Then Walley turned to a new effort — the Southeast Chicago Archive and Storytelling Project, an online repository of objects and images, as well as new video features about the industry, labor history, and the local community. The project was  developed in collaboration with a team from the Southeast Chicago Historical Society, which in 1985 opened a museum about the steelworking life. This award-winning newer online project has been supported, in part, by MIT, the National Endowment for the Humanities, and others.

The idea is to use objects to tell stories about the area’s history. To mark Labor Day, MIT News offers this photo essay based on materials from the Southeast Chicago Archive and Storytelling Project, recognizing America’s workers — and reflecting on the jobs, work, and life produced by industry and innovation. 

It’s hard to depict the vastness of Southeast Chicago’s steel manufacturing area, which stretched for miles into Northwest Indiana and included mills that employed 120,000 workers at their peak. This vintage postcard shows the industry along the Calumet River. 

MIT’s 12th president, Howard Johnson, grew up in the area during the Great Depression, where family members toiled in the mills. Johnson’s father worked for U.S. Steel for 50 years, becoming a bookkeeper and accountant, and Johnson attended Bowen High School, which is still open today.

“Families — ours and thousands like it — were the essential centers of life in the community,” Johnson writes in his memoir, published by the MIT Press.

Families have also been essential to the Southeast Chicago Archive and Storytelling Project, which displays more than 1,100 items from the local historical museum’s collection: clothing, photos, scrapbooks, news clippings, recreational objects, oral history materials, and more. Walley says that anyone could take this approach, and use objects to tell stories about their own local history, work, and community life.

“People tend to experience history in their day-to-day lives not through books written by experts, but by telling stories around family objects and photos,” Walley says. “What is meaningful to us about the things we save from the past? Might these items be ‘clues’ that take us on a deeper historical journey?”

Kitty Kalwasinski Markovich (above, left) didn’t set out to become a welder — but as one, she nearly appeared the movies. Born Kazmira Kalwasinski, she immigrated with her family to Chicago from Poland in 1913, at age 10. During World War II, the steel mills sought replacements for men serving in the military, and she started welding at the South Works of U.S. Steel in Chicago. 

Warner Brothers depicted her in this photo shoot (with Florence Josephs, right), as a worker in the “Rosie the Riveter” mode, and considered making a film featuring her. Five of her brothers served in the military, and their names are seen on Markovich’s welding helmet. One of them, Frank Kalwasinski, was killed in World War II, and his sacrifice is represented by the solid star.

Although many American women returned to their former lives as homemakers at the conclusion of the war, Markovich kept working in the mills, welding for 23 years in the South Works before she retired in 1967. It’s also where she met her husband, Michael Markovich. Kitty Kalwasinski Markovich’s family donated many materials to the Southeast Chicago Archive and Storytelling Project. 

This hard hat, made around 1986, was donated to the Southeast Chicago Historical Museum along with a cutting from the last beam ever produced at U.S. Steel’s once-mighty South Works, which closed in 1992, having produced steel since the 1800s. 

At its peak, South Works employed about 20,000 people. The Chicago steel mill closures, the 1970s through the 1990s, devastated employees and their families who, as Walley details in the “Exit Zero” book, identified strongly with steelworking. Her own father was a third-generation steelworker.

The online storytelling project deploys MIT scholar Sherry Turkle’s notion of “evocative objects,” those that hold great resonance and get our minds in motion. As Turkle writes, “we love the objects we think with.” 

Donated to the museum by James Stapay, this hard hat evokes the end of a long industrial era in Chicago, and is featured in “The Closing of the Mills,” one of the project’s four documentary videos created from donated objects.

Working in steel mills was not just physically demanding, but dangerous. Worker injuries and deaths were a recognized problem, especially in the early years. This is prototype safety gear from around 1911-12, from a series of photo albums donated to the Southeast Chicago Historical Society by U.S. Steel itself in the 1980s. 

U.S. Steel set up a Committee of Safety early in the 1900s, which recommended 3,000 changes to operations. However, in oral history interviews, workers often recount continuing dangers and terrible accidents in the steel mills. 

Some first-person accounts state that as late as the 1960s, workers were still not regularly wearing hard hats. Basic safety practices seemed to improve, though, after the introduction of the U.S. Occupational Safety and Health Administration in 1970. Worker safety was a long-term work in progress. 

Many of the close-knit communities formed around the mills have donated materials to the project that range far beyond the factory. For instance, family recreation was important in steelworks neighborhoods. Pictured here, in a photo donated by the Cordero family, is the “Mayas” softball team, made up of members of Southeast Chicago’s Mexican-American community, which won a 1937 community league championship.

Justino Cordero immigrated to Chicago in 1923, became a steelworker, then eventually did electrical work in the mills while opening a radio shop. Cordero, a father of three (two of his children are pictured), organized and coached youth sports teams to keep kids “out of trouble”; wrote a column for The Daily Calumet, a local newspaper; and was involved with his church, Our Lady of Guadalupe. After retirement, Cordero earned undergraduate and master’s degrees, to work with children with disabilities.

Another documentary video from the Southeast Chicago Archive and Storytelling Project, “Mexican-American Journeys,” explores the long history of Mexican-American steelworkers in Chicago, in many dimensions. At least a dozen parishoners of Our Lady of Guadalupe members who had been in the U.S. military in the 1960s were killed in the Vietnam War, serving their country. 

In 1937, steelworkers went on strike in Chicago. On Memorial Day, during a peaceful protest at Republic Steel, 10 workers were killed by law enforcement officials — an event that provoked congressional hearings in Washington. The image at left is a poster made up for Local 1033, the union branch for the Republic Steel plant; at right, Local 1033 workers take a vote in later years. 

While the so-called “Memorial Day Massacre” was a landmark event in national labor history, it is remembered in more intimate ways in the local area, with many families later donating photos, news clippings, scrapbooks, and interviews about it to the Southeast Chicago Historical Society. 

And though the Southeast Chicago Archive and Storytelling Project project focuses heavily on working-class employment and daily life, there are many other possibilities for U.S. community-based history, involving almost any topic. Whatever the places, objects, and stories, but the goal is the same: to keep the past alive. 

It started with a vision: Move MIT’s School of Architecture and Planning (SA+P) into the Metropolitan Storage Warehouse, an unoccupied, fortress-like brick building on MIT’s campus in Cambridge, Massachusetts.

After all, SA+P needed more space and new facilities. And here, visible from its old offices across the street, was an unused building the size of an airplane hangar. It could offer bigger studios, more work areas, an auditorium, and galleries for events, and become a campus-wide hub for teaching, research, and public engagement. 

“MIT thrives on this idea that we’re all connected,” says Hashim Sarkis, dean of SA+P and a key proponent of the project.

But that vision required hundreds of design decisions: how to bring light into the building, create workspaces and circulation, encourage communication among the school’s populations, and more.

“The conception of the project was not like an automatic flash,” says Elizabeth Diller, founding partner at Diller Scofido + Renfro (DS+R), the architecture firm that was selected to revamp the Met Warehouse, as it’s now called.

“It was a very challenging building to work with,” says Benjamin Gilmartin, another DS+R partner. “There was a lot of innovation needed.”

Innovation is welcome at MIT, however. 

“They transformed the Met Warehouse toward the things we want, which is to do more collaborative work, and to combine instruction and research,” Sarkis says. 

Here’s how DS+R, working with MIT over several years, created the new Met Warehouse — which has a ceremonial moving-in procession on Sept. 8. 

Five buildings in one 

The Met Warehouse was built in several phases starting in 1894; by 1923 it was a five-story building with 2-foot-thick brick walls and 1,500 storage units inside. It was a fortress used for private storage, with the words “Metropolitan Storage Warehouse Fire Proof” painted on the side, visible from across the river in Boston. 

The structure was built in five segments, over time. That became crucial to its transformation. Diller and Gilmartin created a large design studio inside each of the segments. 

“When you start a project like this, there are some big moves that seem very clear and obvious,” Diller says. “There are five buildings that were built basically in succession, making for a 500-foot long building. That is just too big, so how do we break it up into neighborhoods? We decided each building itself would have a stack of floating studios in it.” 

That was essential for SA+P and the components of it that will use the building, such as the MIT Morningside Academy for Design, which was established through a $100 million gift from the Morningside Foundation, the philanthropic arm of the T.H. Chan family. This founding gift from family members Gerald and Beryl Chan and Ronnie and Barbara Chan included support for the Met Warehouse transformation. 

Each building segment features double-height, column-free studios which, thanks to virtuoso engineering, are suspended from roof trusses that bring the weight back down to the existing structure. 

Those spaces will benefit the interdisciplinary work taking place at MIT. 

“In those five spaces, we’re putting the making and the research together,” Sarkis says. “The studio and the lab will become one and the same.”

Bringing in light

For about a century, the Met Warehouse featured tiny window slits as its only apertures. That raised a question: How could natural light be brought inside? 

DS+R produced a dramatic answer, drawn from recent architectural history. Along the long north side of the Met Warehouse, adjacent to a set of railroad tracks, they carved large voids for the studios. Aligned with the studios, large segments of the brick exterior were replaced with glass facades.

This way, natural light pours into the studios and beyond, while occupants look out to a lively Cambridge cityscape.

“The process was like an extraction of the dense mass of the building to create open and light-filled space connecting all,” Diller says. 

Her aesthetic inspiration included the artist Gordon Matta-Clark, known for making bold cuts into New York City buildings in the 1970s. 

“Right from the beginning there was a nod to Gordon Matta-Clark,” Diller says, though she notes that Matta-Clark’s work consisted of building-scale interventions motivated by political and social critique. Whereas, “In our case, we use subtraction to build — to make space for new uses and to expose the anatomy of the building.” 

The living lab

To ensure the huge cuts and windows would work, MIT collaborated with DS+R, as well as Leers Weinzapfel Associates, the project’s associate architects, and Shawmut Design and Construction, to test slab cuts and window arrangements directly in the Met Warehouse itself.

“This hands-on approach allowed us to prove the design concepts through actual construction methodologies and logistics,” says Nicole Bernabei, a senior project manager for campus construction at MIT, who has worked on the Met Warehouse effort since 2018. 

Those slices into the building, needed to create the studios, revealed the Met Warehouse’s original structural features as cross-sections now appearing in walls. The designers envisioned those cuts as features to remain visible, something students can still learn from.

“For a school of architecture and planning, this approach feels especially fitting,” Bernabei says. “The building itself has become a teaching tool — a living laboratory where students, faculty, staff, and visitors experience how rigorous design thinking translates into a built reality. Every detail, from the celebrated slab edges to the transformative light, tells the story of collaboration and precision.”

And while those issues were being addressed, the architects had to grapple with, well, everything else. 

Asymmetry inside

There is another reason the architects placed the huge glass walls on the north side of the Met Warehouse. The Cambridge Historical Commission (CHC) asked MIT to keep the building’s south and east sides essentially intact. The long south facade, the one historically visible from Boston, was particularly significant.

“Changing the building’s surface there [on the north side], bringing in the large glass, wouldn’t impact the character of the building as it would on the south side,” Diller says. For that reason, in the interior, “the big spaces drift to the north.” 

The architects placed smaller spaces, like offices, on the south side. 

“The fabric of the existing Met Warehouse building, with its column grids, offered a lot of opportunities for more serialized smaller spaces where you can have seminars, faculty offices, teaching spaces, research areas, next to and in dialogue with the larger multistory spaces that we introduced,” Gilmartin says. 

So, the Met Warehouse is asymmetric inside: big studios extending from the north side, across much of the building; and smaller rooms on the south side.

It was not obvious how to bring more light into the south-side rooms, however. But an extended dialogue between DS+R, MIT, and the CHC produced an “intersect window” strategy — box frame windows sometimes intersecting with the small apertures already on the south side. The steel frames of the new windows, now at a proper height for looking out, distribute the weight of the brick and stone sills once carried by the solid brick that was removed. 

“This meeting of the old and new satisfied the Cambridge Historical Commission’s desire for a minimal touch, but also created an unexpected and delightfully playful effect on the south facade,” says Morgan Pinney MArch ’10, a senior campus planner at MIT. The project, she adds, “allowed us to step into an exceptionally collaborative working relationship with CHC staff — one MIT is very proud of and will certainly continue to build upon for years to come.”

The unusual layout grants a centrality to the studio areas while ensuring that a full range of other spaces are wrapped around them. 

“The logic of the building is that making things is in the middle,” says Sarkis, referring to the studio spaces. “This is MIT. There is making and research in the studios, with seminar rooms and offices all around.” Referring to the school motto, “mens et manus,” he adds, “That’s our culture. MIT is about mind and hand.” 

Still, Sarkis and the architects wanted another element inside, too: interior passages connecting it all.   

Extending the Infinite Corridor

MIT’s main group of buildings features the Infinite Corridor, a busy walkway spanning one-sixth of a mile indoors, linking many other spaces. MIT leaders thought the Met Warehouse could extend the concept. 

“We conceived of it as having an ‘Infinite Corridor,’” says Sarkis, who hoped the corridor would be “visible and accessible all the way through.”

Diller, the architect behind New York City’s High Line, which turned elevated railroad tracks into a wildly popular urban park, knows about getting people walking. She wanted Met Warehouse occupants to “share a circulation system.”

And so every floor of the Met Warehouse has its own “infinite” corridor. Some overlook studio space one floor down, with the cityscape beyond, echoing High Line atmospherics. The off-center circulation spine connects the large studios on the north side and the offices at the south edge of the building. Being flexible about that placement allowed the whole Met Warehouse plan to work. 

“That helps create the space for the large studios,” says John Ochsendorf, director of the MIT Morningside Academy for Design. Besides, he offers, “There’s a happy alignment between historical protection of the south facade, and where the sun is in the sky most of the year. You don’t want direct sunlight on the south side” — where glass walls would create a greenhouse effect — “and the city wanted to protect that view. The architects found this balance.”

A vertical vision

Meanwhile, the architects designed large stairs that pierce through the corridors, helping people access all floors of the building. 

“We didn’t want a layering of the building with horizontal stratification,” Gilmartin says. The stairs will provide “moments of serendipity and exchange with other people.”

The first time Gilmartin drafted stairs for the building, they were “more blade-like and expressive formally” than the final version. But MIT asked for a stripped-down sensibility, so Gilmartin made the design “almost as simple as it could be.”

The stairs still have expansive scope and meeting-place potential.

“That central spine stair is sort of a ceremonial stair,” Diller says. “To see and be seen. I think it will be lively.”

Culture change

The Met Warehouse is very different from the previous quarters of SA+P, a warren of rooms in MIT’s buildings 7 and 9. Many peer institutions have design studios that place all students in a large common space. Not MIT, which has had a different culture, with smaller, specialized design spaces.

Now, the Met Warehouse does feature larger and more visible design areas. 

“We’re trying to give the school the ability to adapt it and change it, and balance the past culture of MIT and a new culture with kinds of spaces where ideas can cross-pollinate and there’s a lot of room for large-scale experimentation,” Gilmartin says. 

Design practice is becoming bigger across MIT, and as more people connect with it, the Met Warehouse will let MIT evolve. 

Gilmartin again: “There’s just a lot of opportunity for smaller groupings of people to be organized in ways that are visible and connected to the larger spaces, but also offer the prospect of a retreat and focused work. I think it is hopefully attuned very well to MIT.” 

The shock of the rebuilt 

It’s unusual to move a major architecture school into an old building. Some of the best-known U.S. universities house their architecture schools in buildings with high-modernist stylings or postwar brutalist aesthetics, heavy on concrete, light on graceful curves. 

“Those buildings come out of the modernist tradition predicated on the shock of the new,” Gilmartin says. “There was something confrontational about those buildings in their material expression and image, and spatial ideas of openness and flexibility, which was quite different from most historic buildings. In their time, they were pretty thrilling.” 

But as the saying goes, that was then, and this is now. 

“The reality of our future is that we can’t tear everything down and build new for every generation,” Gilmartin says. The Met Warehouse “makes a claim about the future of design and what the orientation of that needs to be, in our work,” he adds. 

MIT agrees. 

“I think it sends a very good message that this vanguard school of architecture, at the Massachusetts Institute of Technology, is moving into a historic building and adapting it for the future,” Sarkis has said. 

Along with the Morningside Foundation, another key project donor was Sidara (formerly the Dar Group), a global collaborative of specialist design, engineering, and consulting firms, owned by Maha and Talal Shair; they have supported the creation of the building’s Sidara Auditorium and Sidara Gallery space.

Adaptive re-use 

Ultimately, DS+R was ideal for the Met Warehouse project because of their experience transforming structures. Besides the High Line, they transformed a London media center built for the 2012 Olympics into the Victoria and Albert Museum’s new open storage facility, the V&A East Storehouse.

Diller suggests the key is being pragmatic.

“When you have a building that is that thick, that heavy, that present, sometimes it’s more expensive to demolish it than to invent a way of reusing it,” she says.

Besides, she adds, “Because it’s an architecture school, it’s important that the students understand adaptive reuse firsthand, as we share a planet with limited resources. It’s a good thing to repurpose buildings, to change their program, to update their innards where possible, rather than just preserving them in formaldehyde — or destroying them and taking away the character of a city.”

The Met Warehouse was old, is new again, and is ready for the MIT community to make it their own.

“Very often contemporary buildings are so sanitized and clinical, you don’t feel like you can touch anything,” Diller says. “It doesn’t feel like home. Here, we wanted students to feel uninhibited — a place that would feel like home.”

The MIT School of Architecture and Planning recognized 11 faculty members with promotions for their significant contributions to the school, effective July 1, 2026. Four faculty promotions are in the Department of Architecture, three are in the Department of Urban Studies and Planning (DUSP), and four are in the program in Media Arts and Sciences.

“These individuals offer the MIT community creativity, knowledge, and scholarship that is exhilarating,” says Hashim Sarkis, dean of the School of Architecture and Planning. “Collectively, they add considerable strength to our faculty and research capacity.”

Vice Provost for International Activities Duane Boning oversees MIT’s international policies and engagements. Here he discusses why international engagement remains vital to MIT’s mission of advancing knowledge, educating students, and innovating to serve the nation and the world.

Q: Why does MIT consider international engagement important to its institutional mission?

A: International engagement is an integral part of what makes MIT strong. It allows us to collaborate with excellent partners, access facilities and research environments unavailable at home, monitor and learn from worldwide progress, and remain closely connected to the world of ideas and innovation.

MIT’s mission is to advance knowledge, educate students, and develop innovations that serve the nation and the world. To do those things well, we have to understand — and help shape — the global landscape of science and technology.

Today’s breakthroughs don’t emerge in isolation. Scientific talent, research facilities, and technological advances are distributed across the world. To ensure that we remain at the forefront of discovery and innovation, we need to know what is happening beyond our borders, collaborate where it serves our mission, and prepare our students to compete in a changing world.

That does not mean engagement without limits. We are open to international collaboration and global talent paired with sensible, risk-based safeguards. We welcome international collaboration where it advances our educational and research mission, while applying rigorous safeguards to protect sensitive research, intellectual property, and national security.

The world is already deeply interconnected, and we believe that thoughtful engagement makes us stronger.

Q: How does engaging this way benefit MIT and the nation?

A: International collaboration is central to keeping MIT and our graduates at the forefront of knowledge and innovation in the 21st century. 

Collaboration is vital to attracting, retaining, and educating the leaders of tomorrow — students, faculty, and researchers from both the United States and around the world — and to feeding MIT's innovative and entrepreneurial spirit. 

Frankly, throughout its history, MIT has flourished in part because of its capacity to attract the world’s very best students, faculty, and researchers — many of whom remain permanent contributors in the United States. These individuals have gone on to teach, deliver breakthroughs, and create American startups.

International partnerships also give MIT researchers access to things that aren’t readily accessible in the United States. For example, MIT researchers working in Singapore were able to test autonomous vehicle technologies years before suitable facilities were widely available domestically. Off the coast of Portugal, MIT researchers are now partnering to develop the next generation of deep-ocean monitoring systems in offshore environments that don’t exist here. The knowledge and insights gained in such settings benefit everything we do.

Q: How is MIT adapting to a changing and more uncertain world?

A: Our mission to serve the nation and the world remains steadfast, but we acknowledge that the world has changed. MIT has rigorous processes for evaluating and mitigating potential risk associated with international engagements in a thoughtful and thorough way, allowing the Institute to engage appropriately in new opportunities when and where possible.

Global collaboration still plays an essential role in advancing research, education, and innovation. But we recognize the challenges of operating within a rapidly shifting environment marked by geopolitical uncertainty, evolving federal funding priorities, regulatory complexity, policy shifts limiting international mobility, and competition for global talent and collaborations.

On the research front, we seek to cultivate relationships across industry, government, and the global alumni community. On education and student experience, we recognize that the United States benefits when American students understand the world around them. It expands opportunities for both undergraduate and graduate students to gain international experience while strengthening relationships with trusted partners and maintaining the flexibility to adapt as global conditions change.

While MIT’s global engagement is partly built on long-standing relationships that have delivered meaningful outcomes for students and researchers, today’s volatile landscape calls for forward-thinking cultivation of new relationships around the world. By investing in new regions, MIT will be better positioned to adapt to changing global circumstances. 

International engagement enables MIT to deepen its impact, strengthen innovation, and enable students and researchers to take part in tackling the world’s most pressing challenges.
