For people at high risk of developing breast cancer, yearly mammograms may not be enough to detect tumors early. To make earlier diagnosis easier, an MIT team has developed portable detectors based on ultrasound, which could be used much more frequently.

In a new paper, the team reports that they have improved the resolution of the images produced by their system, making it easier to spot potential tumors, as well as cysts and microcalcifications. The researchers also created a user interface that makes it simple to use the ultrasound probe, even for people with no expertise in ultrasonography.

This system, they believe, could not only enable earlier detection, but also allow for long-term monitoring following breast cancer treatment — either in a doctor’s office or at home.

“At each time interval, the computer interface guides you to position the device in exactly the same location, which is important for the longitudinal monitoring of a given tissue. It’s very intuitive and quite easy to use,” says Canan Dagdeviren, an associate professor of media arts and sciences at MIT and the senior author of the study.

Former MIT postdoc Md Osman Goni Nayeem and MIT graduate students Shrihari Viswanath and Hyeokjun Yoon are the lead authors of the paper, which appears today in Nature Communications.

Higher-quality imaging

While many people receive annual mammograms to check for breast cancer, it is possible for cancer to develop in between these annual screenings. These cancers, known as interval cancers, tend to be more aggressive, and they account for 20 to 30 percent of all breast cancer cases.

After losing an aunt to an interval breast cancer in 2015, Dagdeviren was motivated to develop a screening technique that would be more effective on women with dense breast tissue and could be performed more often than mammography. She decided on ultrasound, which uses sound waves to create images of tissue. Ultrasounds are often used to follow up on abnormal mammograms, but current ultrasound technology requires large equipment and a trained operator.

Earlier this year, Dagdeviren’s lab published a study in which they demonstrated a small ultrasound probe attached to an acquisition and processing module that is a little larger than a smartphone. This compact system can create a 3D image of the entire breast by scanning just two or three locations.

In the new Nature Communications study, the researchers reported several advances that allow for higher resolution imaging and greater ease of use.

One key advance is the addition of a “backing layer” to the ultrasound transducer. This layer helps to contain and focus the ultrasound waves, improving the resolution and quality of the resulting images. It also increases the range of soundwave frequencies that can be absorbed, and reduces both acoustical noise and electrical noise, further enhancing the images.

“With the backing layer, the device produces more accurate and sharper images, with a wider operating range of frequencies,” Nayeem says.

To further improve the quality of the images, the researchers designed an algorithm that adaptively performs a process called beamforming. This algorithm allows the system to compensate for differences in the speed at which sound waves travel through different types of tissue, such as skin and fat. 

“What we are trying to do is predict the speed of sound properties of the tissue you’re imaging, and then use that to reconstruct the image more accurately. We see up to a 10 percent improvement in the resolution just by applying this technique,” Viswanath says. 

The researchers asked 10 volunteers, who were not experts in ultrasound technology, to use the system to try to identify small micro targets embedded in a “tissue phantom” — a gel-like material engineered to mimic human tissue. Participants had a much higher success rate locating the spheres when they used the new system than when they used a traditional ultrasound probe.

A user-friendly system

For the new version of this system, the researchers also created a user interface, displayed on a computer screen, that guides the user to place the probe in the correct location. This could be especially important for tracking progression of treatments such as neoadjuvent therapy, or long-term monitoring of known abnormalities such as fibroadenomas or microcalcifications.

In a trial with seven people, the researchers found that the users were able to accurately place the probe in the correct location each time they did a scan. 

“Conventionally, you need an operator to move the probe around the breast, but we made a computer-vision interface for users to do it by themselves. This is very user-friendly and it shows live images on the screen,” Yoon says.

For future versions of this technology, the researchers hope to create an interface that could be used with a cellphone or tablet, making the system easier to carry. In addition to enabling earlier diagnosis, this type of system could make ultrasound more accessible to patients in areas where there aren’t enough trained ultrasound technicians, the researchers say.

Dagdeviren and some of her students now hope to form a company to work toward making the technology commercially available. While breast cancer diagnosis is their first target application, they hope to expand it to many others.

“The technology is so versatile that it can be used for any soft tissue imaging, from ovarian cancer to measuring endometriosis progression, or fetal monitoring,” Dagdeviren says.

The research was funded by the National Science Foundation, the 3M Non-Tenured Faculty Award, the Lyda Hill Foundation, the MIT Media Lab Consortium, and a Tata Center Technology and Design Fellowship.

A new big-data analysis of the U.S. pinpoints how urban design aids the health of city residents — especially when cities provide walking opportunities, greenery, and mixed-use streets with a blend of commercial and residential activity. 

The study examines tens of thousands of urban census-bureau tracts in the U.S., seeing how city features correlate with population health measures, while accounting for socioeconomic considerations as well. 

“We found that on a very large scale, urban planning and design, such as the availability of different amenities and their spatial arrangement, plays a critical role in population health outomes,” says Winston Yap, a visiting scholar at the MIT Senseable City Lab, a postdoc at Cornell University, and co-author of a new paper outlining the study’s findings. 

While there is not one design template for all locations, short and well-connected blocks with a variety of amenities, as well as the strategic placement of parks, all help well-being — physiologically and psychologically. 

“We usually think about physical health first, but we also found a high correlation between good design and mental health,” says Fabio Duarte, an MIT researcher and co-author of the paper. “If you are walking more, it is not only a matter of physical fitness, but gives people a chance to avoid isolation, have serendipitous meetings with people, and at least see there are others around.”

The paper, “Urban motifs associated with population health,” appears today in Nature Health. The authors are Yap; Duarte, who is associate director and a principal research scientist at MIT Senseable City Lab; postdocs Yu Zheng, Kee Moon Zhang, and Peng Luo, who is also an incoming assistant professor at the University of Iowa; Paolo Vineis, a professor at Imperial College, London; Carlo Ratti, director of the MIT Senseable City Lab; and Filip Biljecki, an associate professor at the National University of Singapore.

Only connect

The researchers say they conducted the analysis not just due to an interest in cities, but out of recognition that health care systems are often swamped, and preventative health measures are ever-more important. 

“We wanted to do this study because health care systems around the world are overloaded,” Yan says. “There’s a lot of burden on health care systems, and there is a need not just for treatment but for prevention as well, for obesity, high cholesterol, depression and other mental health issues, and more.” 

To conduct the study, the researchers analyzed 28,323 census tracts, using data from the U.S. Census Bureau along with health data from the U.S. Center for Disease Control and Prevention (CDC). They then used geospatial data, including more than 8 million street view images, to see how urban form related to the health status of residents in those areas. The study accounts for socioeconomic factors and other variables in building an assessment of the relationship between design and health. The study confimed that by themselves, socioeconomic factors are associated with urban health disparities; it then examined the relative impact of differences in urban design in those different settings. 

“By bringing together open demographic, health, and environmental data, the study highlights the importance of open data accessibility for planning healthy cities,” says Ratti.

The scholars also applied a graph deep-learning model to the data, an emerging machine-learning technique they used to help understand which key factors in urban design are most connected to health outcomes. 

The research reveals that in some cases, rectangularity in city blocks, and “building spread,” meaning structures that cover the full size of their lots, can enhance wellness. Examples of this include Manhattan or Boston’s Back Bay neighborhood, where mixed-use buildings on relatively short blocks create many amenities and a variety of walking routes. That said, circular and curving street forms can also work, as long as they feature a lot of interconnectedness as well. 

Urban greenery is almost always a significant factor in urban wellness, with parks scoring high as a facet of city design that helps resident health. Beyond that, expanding the tree canopy can also help urban health outcomes. 

The presence of cultural institutions and restaurants are also linked to general health, while access to health care amenities are understandably connected to physical health improvements. In general, access to points of interest, broadly defined, whether cultural or commercial, is a significant factor in abetting better health, in cities across the country. 

“One of the major contributions of the study is that we look at not only one or two cities, but the entire United States,” Yap says. “In a large-scale study, we were trying to find patterns that were consistent across different urban contexts, as well as populations with different characteristics. Just using this data, we can predict very confidently the population health outcomes for a neighborhood.”

Knowing where to intervene

The research also provides a kind of road map for urban planners and city officials when it comes to policy decisions and local improvements. Among other things, the study suggests where cities might see the greatest return on investment in urban improvements, in health terms. Improvements in lower-income neighborhoods, on aggregate, may generate about four times the added health benefits than the same level of investment in better-off areas that already realize the benefits of good urban amenities. 

“It’s important to know where to intervene,” Yan says. 

“I think for me it shows how intertwined different policies are,” Duarte adds. “Some funding for urban development could have a direct influence on health, and could be more inexpensive than [direct spending on health].”

The researchers regard the study as just one empirical step in this domain. As they note, additional studies could observe changes over time, to further enhance our picture of the connection between urban design and health. Still, as the authors write in the paper, “we believe that our broad picture provides an overarching scaffolding for the understanding of the social and material determinants of health and can guide [further] analytical studies.”

Publisher Correction: Multi-centennial response of marine carbon pumps to global warming

For decades, neuroscientists have known that specific regions in the brain’s left hemisphere are responsible for processing language. However, a new study by MIT researchers shows that language processing also occurs in many other parts of the brain.

Using functional magnetic resonance imaging (fMRI) data from more than 700 people, the researchers identified 17 additional regions of the brain that appear to play a role in language. These regions are scattered across the brain, including parts of the cerebellum, hippocampus, and cerebral cortex, and they make up about 5 percent of the total volume of the adult brain — about the size of a large strawberry.

“Even though there are all these distant components, it’s pretty restricted in terms of volume. You don’t need that much of the brain to do language,” says Evelina Fedorenko, an MIT associate professor of brain and cognitive sciences, a member of MIT’s McGovern Institute for Brain Research,and the senior author of the study.

Exactly how these regions contribute to language processing is still to be discovered, although the researchers have made some progress toward determining the functions of the cerebellar regions that they identified.

MIT postdoc Agata Wolna is the lead author of the paper, which appears in the Journal of Neuroscience. Other authors include Aaron Wright, a K. Lisa Yang Post-Baccalaureate Research Scholar at MIT; Colton Casto, a graduate student at Harvard University; Samuel Hutchinson, a graduate student at MIT; and Benjamin Lipkin PhD ’26.

Tracking language

The brain’s language processing centers include Broca’s area, first discovered in the 1800s, plus additional regions in the left frontal and temporal lobes of the brain. Scientists have found that some of the corresponding areas of the right hemisphere also contribute to processing language, especially the social-emotional components of language.

There have also been hints that other parts of the brain might be involved in language processing. Early in her career, Fedorenko’s language studies often showed active brain regions outside of the canonical language centers, but she says she was discouraged from including them in her papers.

“When we initially started looking at language, in the first couple of papers, I tried to be comprehensive and include anything that seemed consistent across participants, and there was a huge amount of resistance,” she says. “People would say things like, ‘Well, we know those are not language areas, so please focus on the language areas.’”

In the new study, she and Wolna wanted to revisit those brain scans and see if they could systematically identify language regions outside of the standard language-processing areas.

To do that, they analyzed data from 772 people who had been scanned in Fedorenko’s lab since 2013. Each of these participants underwent a task known as a language localizer, which is used to determine the location of language processing areas for each subject. 

During the test, participants read or listen to sentences as well as sequences of nonwords. For each person, the researchers measure the difference in strength of response when reading real sentences or nonsense sequences. The brain areas that work harder during the sentence condition are considered to be doing something relevant to language, especially if they respond while both reading and listening to sentences.

“It’s a very simple paradigm that lets you identify this core language system in individual brains,” Wolna says.

When searching for language areas, the researchers usually use a relatively strict statistical threshold. In this study, they relaxed the threshold and also used some targeted searches in subcortical areas, in hopes of finding all areas that may contribute to language processing.“We always see this frontal temporal network, but there’s quite a lot of evidence that there are other regions that are also critical for language processing,” Wolna says. “By using a laxer threshold and zooming in on areas with weak MRI signal, we tried to maximize the chances of finding small and weakly responsive regions outside of this left frontal temporal system.”

A widespread network

For about 490 of the participants, the researchers also had data on how their brain responded during a spatial working memory task — remembering the locations of flashing squares on a grid. This task engages a brain network called the multiple demand system, which does not overlap with the core language areas.

This task allowed the researchers to ask whether any of the newly identified language-sensitive regions specifically respond to language and not more general cognitive processes.

Of the 17 new language sites that were revealed by this study, five are located in the cerebellum, which is mainly involved in coordinating the body’s movement. In a study published earlier this year, researchers led by Casto found that three of those cerebellar regions also became engaged during some nonlinguistic cognitive tasks, which was also seen in the new study.

“Those areas that respond to both language and some other tasks could be really interesting and important because they may be doing something like integrating information from different cortical systems,” Fedorenko says.

They also found language-selective regions in the medial frontal cortex, the bottom surface of the left temporal lobe, the hippocampus, and the amygdala. The researchers now plan to further study how these brain regions might contribute to language processing.

“We can now test some ideas from past work, and also more rigorously characterize these regions across different kinds of language manipulations, and different kinds of nonlinguistic tasks, to try to understand what it is that they’re doing,” Fedorenko says.

The research was funded by the Simons Center for the Social Brain at MIT, the McGovern Institute, MIT’s Department of Brain and Cognitive Sciences, and the MIT Siegel Family Quest for Intelligence.

As a new academic year dawns, the MIT-Kalaniyot program is welcoming its second cohort of scholars to campus, expanding an innovative effort to build new connections between MIT and researchers from Israel. 

In fall 2026, MIT-Kalaniyot has 11 new scholars arriving at MIT to pursue research, collaborating with Institute faculty across a wide variety of disciplines. They consist of seven new Kalaniyot Postdoctoral Fellows and four new Kalaniyot Sabbatical Scholars, who are faculty on leave from institutions in Israel. 

It is another step forward for a program which, less than two years ago was still an idea on a drawing board. The project aims to enhance research and create stronger community ties — not only among those connected to the program, but across the MIT campus.

“The goals of the program are to build academic ties between MIT and Israel, alongside a strong, supportive community,” says Or Hen, an MIT nuclear physicist and a co-founder of MIT-Kalaniyot. “MIT has a mission that revolves around research, education, and entrepreneurship, and MIT-Kalaniyot strengthens MIT, to help meet that mission for the world.”

The scholars will be working on a wide range of topics, including mathematics, materials science, behavioral economics, architecture, modern history, chemistry, quantum computing, and computational methods for examining cellular activity.

“We designed Kalaniyot to strengthen MIT’s research and its community at the same time,” says Ernest Fraenkel, a professor of biological engineering and a co-founder of  MIT-Kalaniyot. “We now have scholars in the program working in each of MIT’s five schools. The academic breadth shows our model is working.” MIT-Kalaniyot will also feature its first teaching fellow at the Institute, hosted by MIT’s History program. 

MIT-Kalaniyot was founded by Hen and Fraenkel as a constructive response to discord over conflict in the Middle East. Hen is the Class of 1956 Associate Professor of Physics and associate director of the Laboratory for Nuclear Science; Fraenkel is the Grover M. Hermann Professor in Health Sciences and Technology.

Fraenkel and Hen credit multiple members of MIT’s community and upper administration for backing the MIT-Kalaniyot idea from the start, making it feasible for the program to launch. 

“When we first shared the idea, we were very encouraged by the response from MIT’s senior leadership,” Fraenkel says. “They understood the value of a faculty-led effort, and their constructive response gave us confidence that our approach could be successful.”

“This would be impossible to do the way we’re doing it without the administration’s support,” Hen says. “The program is faculty-led and institution-backed. That’s what you want.”

Hen adds: “I think MIT today is home to one of the most, if not the most, accepting and welcoming communities for Israelis, and I can stand by that statement very strongly. The way our community grew these past years is remarkable.”

Embedded at MIT

MIT-Kalaniyot, named for a well-known flower that grows in Israel and other parts of the region, welcomed its first cohort of scholars to the MIT campus for the 2025-26 academic year. Hen and Fraenkel also give Tal Cohen, an associate professor in MIT’s Department of Civil and Environmental Engineering, substantial credit for developing the concept. 

Scholars at Israel’s nine state-recognized universities are eligible to seek the MIT-Kalaniyot fellowships, which enable research, collaboration, and training at the Institute. The scholars come from a range of academic and personal backgrounds, including both Arab and Jewish citizens of Israel. 

The program is highly competitive, with many more applicants than positions currently available. Applicants are encouraged to identify in advance MIT faculty they would like to work with; accepted applicants then already have a “faculty host” lined up. Many of the new fellows will be working with researchers in established MIT labs, for instance. 

“When they’re here, they are treated exactly like anybody else in an academic unit at MIT and that’s really important,” Fraenkel says. “They’re embedded in these places.”

The program is also intended to generate the kinds of community connections that help scholars flourish, both professionally and personally. MIT-Kalaniyot features weekly lunches, attended by people from the larger community, where scholars can forge connections and friendship. 

The program also features informal academic talks and discussions, with the talks given by MIT researchers both within and outside of MIT-Kalaniyot. Hen, for one, has already seen the benefits of such events; one paper he has recently co-authored directly stemmed from discussions he had at a program event. 

“The range of MIT faculty who stepped forward as hosts has been one of the most gratifying parts of the program,” Fraenkel says. “It shows that this is not confined to one field or one corner of the Institute. It is becoming part of MIT’s broader academic life.”

Adds Hen: “I think it sends a very strong and important message. We’re able to move forward at MIT and build collaborative partnerships with strong ties.”

An additional facet of the program is the potential impact of MIT-based research in practical, tangible ways. One of the 2025 fellows, a leading physician, focused her MIT work on new methods of breast cancer detection, and now, back in Israel, is working to apply those findings in active medical settings. 

Plans for future growth

Having first taken root at MIT, the MIT-Kalaniyot concept is now spreading to other places. In the last two years, Columbia University, Cornell University, Dartmouth College, Harvard University, the University of Pennsylvania, and the University of Southern California have implemented the concept, with other universities in the process of adopting it as well. 

“This national movement all started by replicating the MIT model,” Hen says. “Each university then innovated in their own way. They start from the MIT approach, and then they adapt to what’s happening on their campus. They learn from us, we learn from them, and together we support a broad academic network.”

The progress at MIT and elsewhere has led Hen and Fraenkel to feel optimistic about the ongoing evolution of MIT-Kalaniyot. 

“We started at a tense time on our campus, not really knowing what the future would hold, and it’s exceeded our hopes,” Fraenkel says. “Now we want Kalaniyot to become a recognized center at MIT, funding seed grants for research that wouldn’t happen any other way.”  

While Fraenkel and Hen do not yet have a firm timetable for those developments, they regard them as being realistic. 

“Now we see Kalaniyot as a program that helps MIT well beyond our community,” Hen says. After all, he observes, simply as a vehicle for research, the program has the potential to provide added capacity for MIT, as well as the further connections to top scholars being generated by the effort. 

Indeed, Hen reflects, he is motivated the question: “How do we best support MIT in realizing its mission for the world?” Overall, he says, “I think that’s the ultimate goal of Kalaniyot. We do it in one way, other people can do it in other ways, and as long as you do net good, and support the MIT mission, we value and treasure that, and just want to be part of it.”

“I really believe this is the DNA of MIT,” Fraenkel says. “We’re all about finding practical solutions to society’s biggest problems. Kalaniyot brings extraordinary people here to do exactly that, and the whole Institute is stronger for it.”
