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.

In September 2024, Amandla Thomas-Johnson was a Ph.D. candidate studying in the U.S. on a student visa when he briefly attended a pro-Palestinian protest. In April 2025, Immigration and Customs Enforcement (ICE) sent Google an administrative subpoena requesting his data. The next month, Google gave Thomas-Johnson's information to ICE without giving him the chance to challenge the subpoena, breaking a nearly decade-long promise to notify users before handing their data to law enforcement. 

Today, the Electronic Frontier Foundation sent complaints to the California and New York Attorneys General asking them to investigate Google for deceptive trade practices for breaking that promise. You can read about the complaints here. Below is Thomas-Johnson's account of his ordeal. 

Out of touch but not out of reach 

I thought my ordeal with U.S. immigration authorities was over a year ago, when I left the country, crossing into Canada at Niagara Falls.  

By that point, the Trump administration had effectively turned federal power against international students like me. After I attended a pro-Palestine protest at Cornell University—for all of five minutes—the administration’s rhetoric about cracking down on students protesting what we saw as genocide forced me into hiding for three months. Federal agents came to my home looking for me. A friend was detained at an airport in Tampa and interrogated about my whereabouts. 

I’m currently a Ph.D. student. Before that, I was a reporter. I’m a dual British and Trinadad and Tobago citizen. I have not been accused of any crime. 

I believed that once I left U.S. territory, I had also left the reach of its authorities. I was wrong. 

The email

Weeks later, in Geneva, Switzerland, I received what looked like a routine email from Google. It informed me that the company had already handed over my account data to the Department of Homeland Security. 

At first, I wasn’t alarmed. I had seen something similar before. An associate of mine, Momodou Taal, had received advance notice from Google and Facebook that his data had been requested. He was given advanced notice of the subpoenas, and law enforcement eventually withdrew them before the companies turned over his data. 

Google had already disclosed my data without telling me.

I assumed I would be given the same opportunity. But the language in my email was different. It was final: “Google has received and responded to legal process from a law enforcement authority compelling the release of information related to your Google Account.” 

Google had already disclosed my data without telling me. There was no opportunity to contest it. 

Google’s broken promise

To be clear, this should not have happened this way. Google promises that it will notify users before their data is handed over in response to legal processes, including administrative subpoenas. That notice is meant to provide a chance to challenge the request. In my case, that safeguard was bypassed. My data was handed over without warning—at the request of an administration targeting students engaged in protected political speech. 

Months later, my lawyer at the Electronic Frontier Foundation obtained the subpoena itself. On paper, the request focused largely on subscriber information: IP addresses, physical address, other identifiers, and session times and durations. 

But taken together, these fragments form something far more powerful—a detailed surveillance profile. IP logs can be used to approximate location. Physical addresses show where you sleep. Session times would show when you were communicating with friends or family. Even without message content, the picture that emerges is intimate and invasive.  

State power meets private data

What this experience has made clear is that anyone can be targeted by law enforcement. And with their massive stores of data, technology companies can facilitate those arbitrary investigations. Together, they can combine state power, corporate data, and algorithmic inference in ways that are difficult to see—and even harder to challenge. 

The consequences of what happened to me are not abstract. I left the United States. But I do not feel that I have left its reach. Being investigated by the federal government is intimidating. Questions run through your head. Am I now a marked individual? Will I face heightened scrutiny if I continue my reporting? Can I travel safely to see family in the Caribbean? 

Who, exactly, can I hold accountable?

This is a current list of where and when I am scheduled to speak:

• I’m speaking at DemocracyXChange 2026 in Toronto, Ontario, Canada, on April 18, 2026.
• I’m speaking at the SANS AI Cybersecurity Summit 2026 in Arlington, Virginia, USA, at 9:40 AM ET on April 20, 2026.

Google's Failure to Warn Users About Law Enforcement Demands for Data Is Deceptive

SAN FRANCISCO – The Electronic Frontier Foundation sent complaints today to the attorneys general of California and New York urging them to investigate Google for deceptive trade practices, related to the company's broken promise to give users prior notice before disclosing their information to law enforcement. 

The letters were sent on behalf of Amandla Thomas-Johnson, whose information was disclosed to U.S. Immigration and Customs Enforcement (ICE) without prior notice from Google. 

For nearly a decade, Google has promised billions of users that it will notify them before disclosing their personal data to law enforcement. Many times, the company has done just that. But through a hidden and systematic practice, Google has likely violated that promise numerous times over the years. This was the case for Thomas-Johnson, a Ph.D. candidate who was targeted by ICE after briefly attending a protest, effectively preventing him from contesting an invalid subpoena for his data. 

"Google should answer the question: How many other times has it broken its promise to users?” said EFF Senior Staff Attorney F. Mario Trujillo. "Advance notice is especially important now, when agencies like ICE are unconstitutionally targeting users for First Amendment-protected activity. State attorneys general should investigate Google for this deception." 

On Google’s Privacy & Terms page, it promises its users that “When we receive a request from a government agency, we send an email to the user account before disclosing information.” This promise ensures that users can protect their own privacy and decide to challenge overbroad or illegal demands on their own behalf.   

But on May 8, 2025, Google complied with an administrative subpoena from ICE seeking Thomas-Johnson’s subscriber information, including his name, address, IP address, and other personal identifiers. Later that same day, the company sent Thomas-Johnson a message telling him it had already complied with the subpoena, which he would have successfully challenged had he been given advance notice. Google received the subpoena in April and had more than a month to alert Thomas-Johnson. 

Communication between EFF and Google later revealed that this is a systematic issue, not an isolated one. When Google does not fulfill a subpoena within a government-provided artificial deadline, the company's outside counsel explained, Google will sometimes comply with the request and provide notice to a user on the same day. The company calls this practice “simultaneous notice.” 

"What this experience has made clear is that anyone can be targeted by law enforcement," said Thomas-Johnson. "And with their massive stores of data, technology companies can facilitate those arbitrary investigations. Who, exactly, can I hold accountable?" 

Google must commit to ending this deception and pay for its past mistakes. The attorneys general of California and New York are empowered to stop deceptive business practices and seek financial restitution stemming from those practices. As EFF writes in its complaints, they should investigate, hold Google to its public promise to give users advanced notice of law enforcement demands, and take appropriate action if necessary.

Interesting paper: “What hackers talk about when they talk about AI: Early-stage diffusion of a cybercrime innovation.”

Abstract: The rapid expansion of artificial intelligence (AI) is raising concerns about its potential to transform cybercrime. Beyond empowering novice offenders, AI stands to intensify the scale and sophistication of attacks by seasoned cybercriminals. This paper examines the evolving relationship between cybercriminals and AI using a unique dataset from a cyber threat intelligence platform. Analyzing more than 160 cybercrime forum conversations collected over seven months, our research reveals how cybercriminals understand AI and discuss how they can exploit its capabilities. Their exchanges reflect growing curiosity about AI’s criminal applications through legal tools and dedicated criminal tools, but also doubts and anxieties about AI’s effectiveness and its effects on their business models and operational security. The study documents attempts to misuse legitimate AI tools and develop bespoke models tailored for illicit purposes. Combining the diffusion of innovation framework with thematic analysis, the paper provides an in-depth view of emerging AI-enabled cybercrime and offers practical insights for law enforcement and policymakers...

Oceans absorb roughly 25 to 30 percent of the carbon dioxide (CO2) that is released into the atmosphere. When this CO2 dissolves in seawater, it forms carbonic acid, making the water more acidic and altering its chemistry. Elevated levels of acidity are harmful to marine life like corals, oysters, and certain plankton that rely on calcium carbonate to build shells and skeletons.

“As the oceans absorb more CO2, the chemistry shifts — increasing bicarbonate while reducing carbonate ion availability — which means shellfish have less carbonate to form shells,” explains Kripa Varanasi, professor of mechanical engineering at MIT. “These changes can propagate through marine ecosystems, affecting organism health and, over time, broader food webs.”

Loss of shellfish can lead to water quality decline, coastal erosion, and other ecosystem disruptions, including significant economic consequences for coastal communities. “The U.S. has such an extensive coastline, and shellfish aquaculture is globally valued at roughly $60 billion,” says Varanasi. “With the right innovations, there is a substantial opportunity to expand domestic production.”

“One might think, ‘this [depletion] could happen in 100 years or something,’ but what we’re finding is that they are already affecting hatcheries and coastal systems today,” he adds. “Without intervention, these trends could significantly alter marine ecosystems and the coastal economies that rely on them over time.”

Varanasi and T. Alan Hatton, the Ralph Landau Professor of Chemical Engineering, Post-Tenure, at MIT, have been collaborating for years to develop methods for removing carbon dioxide from seawater and turn acidic water back to alkaline. In recent years, they’ve partnered with researchers at the University of Maine Darling Marine Center to deploy the method in hatcheries.

“The way we farm oysters, we spawn them in special tanks and rear them through about a two-week larval period … until they’re big enough so that they can be transferred out into the river as the water warms up,” explains Bill Mook, founder of Mook Sea Farm. Around 2009, he noticed problems with production of early-stage larvae. “It was a catastrophe. We lost several hundred thousand dollars’ worth of production,” he says.

Ultimately, the problem was identified as the low pH of the water that was being brought in: The water was too acidic. The farm’s initial strategy, a common practice in oyster farming, was to buffer the water by adding sodium bicarbonate. The new approach avoids the use of chemicals or minerals.

“A lot of researchers are studying direct air capture, but very few are working in the ocean-capture space,” explains Hatton. “Our approach is to use electricity, in an electrochemical manner, rather than add chemicals to manipulate the solution pH.”

The method uses reactive electrodes to release protons into seawater that is collected and fed into the cells, driving the release of the dissolved carbon dioxide from the water. The cyclic process acidifies the water to convert dissolved inorganic bicarbonates to molecular carbon dioxide, which is collected as a gas under vacuum. The water is then fed to a second set of cells with a reversed voltage to recover the protons and turn the acidic water back to alkaline before releasing it back to the sea.

Maine’s Damariscotta River Estuary, where Mook farms is located, provides about 70 percent of the state’s oyster crop. Damian Brady, a professor of oceanography based at the University of Maine and key collaborator on the project, says the Damariscotta community has “grown into an oyster-producing powerhouse … [that is] not only part of the economy, but part of the culture.” He adds, “there’s actually a huge amount that we could learn if we couple the engineering at MIT with the aquaculture science here at the University of Maine.”

“The scientific underpinning of our hypothesis was that these bivalve shellfish, including oysters, need calcium carbonate in order to form their shells,” says Simon Rufer PhD ’25, a former student in Varanasi’s lab and now CEO and co-founder of CoFlo Medical. “By alkalizing the water, we actually make it easier for the oysters to form and maintain their shells.”

In trials conducted by the team, results first showed that the approach is biocompatible and doesn't kill the larvae, and later showed that the oysters treated by MIT's buffer approach did better than mineral or chemical approaches. Importantly, Hatton also notes, the process creates no waste products. Ocean water goes in, CO2 comes out. This captured CO2 can potentially be used for other applications, including to grow algae to be used as food for shellfish.

Varanasi and Hatton first introduced their approach in 2023. Their most recent paper, “Thermodynamics of Electrochemical Marine Inorganic Carbon Removal,” which was published last year in journal Environmental Science & Technology, outlines the overall thermodynamics of the process and presents a design tool to compare different carbon removal processes. The team received a “plus-up award” from ARPA-E to collaborate with University of Maine and further develop and scale the technology for application in aquaculture environments.

Brady says the project represents another avenue for aquaculture to contribute to climate change mitigation and adaptation. “It pushes a new technology for removing carbon dioxide from ocean environments forward simultaneously,” says Brady. “If they can be coupled, aquaculture and carbon dioxide removal improve each other’s bottom line."

Through the collaboration, the team is improving the robustness of the cells and learning about their function in real ocean environments. The project aims to scale up the technology, and to have significant impact on climate and the environment, but it includes another big focus.

“It’s also about jobs,” says Varanasi. “It’s about supporting the local economy and coastal communities who rely on aquaculture for their livelihood. We could usher in a whole new resilient blue economy. We think that this is only the beginning. What we have developed can really be scaled.”

Mook says the work is very much an applied science, “[and] because it’s applied science, it means that we benefit hugely from being connected and plugged into academic institutions that are doing research very relevant to our livelihoods. Without science, we don’t have a prayer of continuing this industry.”

California’s bill, A.B. 2047, will not only mandate censorware — software which exists to bluntly block your speech as a user — on all 3D printers; it will also criminalize the use of open-source alternatives. Repeating the mistakes of Digital Rights Management (DRM) technologies won’t make anyone safer. What it will do is hurt innovation in the state and risk a slew of new consumer harms, ranging from surveillance to platform lock-in. California must stand with creators and reject this legislation before it’s too late.

3D printing might evoke images of props from blockbuster films, rapid prototyping, medical research, or even affordable repair parts. Yet for a growing number of legislators, the perceived threat of “ghost guns” is a reason to impose restrictions on all 3D printers. Despite 3D printing of guns already being rare and banned under existing law, California may outright criminalize any user having control over their own device. 

This bill is a gift for the biggest 3D printer manufacturers looking to adopt HP’s approach to 2D printing: criminalize altering your printer’s code, lock users into your own ecosystem, and let enshittification run its course. Even worse, algorithmic print blocking will never work for its intended purpose, but it will threaten consumer choice, free expression, and privacy.

A misstep here can have serious repercussions across the whole 3D printing industry, lead the way for more bad bills, and leave California with an expensive and ineffective bureaucratic mess.

What’s in the California Proposal?

Compared to the Washington and New York laws proposed this year, California’s is the most troubling. It criminalizes open source, reduces consumer choice, and creates a bureaucratic burden.

Criminalizing Open Source and User Control

A.B. 2047 goes further than any other legislation on algorithmic print-blocking by making it a misdemeanor for the owners of these devices to disable, deactivate, or otherwise circumvent these mandated algorithms. Not only does this effectively criminalize use of any third-party, open-source 3D printer firmware, but it also enables print-blocking algorithms to parallel anti-consumer behaviors seen with DRM.

Manufacturers will be able to lock users into first-party tools, parts, and “consumables” (analogous to how 2D printer ink works). They will also be able to mandate purchases through first-party stores, imposing a heavy platform tax. Additionally, manufacturers could force regular upgrade cycles through planned obsolescence by ceasing updates to a printer’s print-blocking system, thereby taking devices out of compliance and making them illegal for consumers to resell. In short, a wide range of anti-consumer practices can be enforced, potentially resulting in criminal charges.

Independent of these deliberate harms manufacturers may inflict, DRM has shown that criminalizing code leads to more barriers to repair, more consumer waste, and far more cybersecurity risks by criminalizing research.

Less Consumer Choice

The bill favors incumbent manufacturers over newer competitors and over the interests of consumers.

Less-established manufacturers will need to dedicate considerable time and resources to implementing the ineffective solutions discussed above, navigating state approval, and potentially paying licensing fees to third-party developers of sham print-blocking software. While these burdens may be absorbed by the biggest producers of this equipment, it considerably raises the barrier to entry on a technology that can otherwise be individually built from scratch with common equipment. The result is clear: fewer options for consumers and more leverage for the biggest producers. 

Retailers will feel this pinch, but the second-hand market will feel it most acutely. Resale is an important property right for people to recoup costs and serves as an important check on inflating prices. But under this bill, such resale risks misdemeanor penalties. 

The bill locks users into a walled garden; it demands manufacturers ensure 3D printers cannot be used with third-party software tools. By creating barriers to the use of popular and need-specific alternatives, this legislation will limit the utility and accessibility of these devices across a broad spectrum of lawful uses.

Bureaucratic Burden 

A.B. 2047’s title 21.1 §3723.633-637 creates a print-blocking bureaucracy, leaning heavily on the California Department of Justice (DOJ). Initially, the DOJ must outline the technical standards for detecting and blocking firearm parts, and later certify print-blocking algorithms and maintain lists of compliant 3D printers. If a printer or software doesn’t make it through this red tape, it will be illegal to sell in the state.

The bill also requires the department to establish a database of banned blueprints that must be blocked by these algorithms. This database and printer list must be continually maintained as new printer models are released and workarounds are discovered, requiring effort from both the DOJ and printer manufacturers. 

For all the cost and burden of creating and maintaining such a database, those efforts will inevitably be outpaced by rapid iterations and workarounds by people breaking existing firearms laws.

Not just California

Once implemented, this infrastructure will be difficult to rein in, causing unintended consequences. The database meant for firearm parts can easily expand to copyright or political speech. Scans meant to be ephemeral can be collected and surveilled. This is cause for concern for everyone, as these levers of control will extend beyond the borders of the Golden State.

While California is at the forefront of print blocking, the impacts will be felt far outside of its borders. Once printer companies have the legal cover to build out anti-competitive and privacy-invasive tools, they will likely be rolled out globally. After all, it is not cost-effective to maintain two forks of software, two inventories of printers, and two distribution channels. Once California has created the infrastructure to censor prints, what else will it be used for?

As we covered in “Print Blocking Won’t Work” these print-blocking efforts are not only doomed to fail, but will render all 3D printer users vulnerable to surveillance either by forcing them into a cloud scanning solution for “on-device” results, or by chaining them to first-party software which must connect to the cloud to regularly update its print blocking system.

This law demands an unfeasible technological solution for something that is already illegal. Not only is this bad legislation with few safeguards, it risks the worst outcomes for grassroots innovation and creativity—both within the state and across the global 3D printing community.

California should reject this legislation before it’s too late, and advocates everywhere should keep an eye out for similar legislation in their states. What happens in California won't just stay in California.

When people see Customs & Border Protection's giant, tethered surveillance blimp flying 20 miles outside of Marfa, Texas, lots of them confuse it with an art installation. Elsewhere along the U.S.-Mexico border, surveillance towers get mistaken for cell-phone towers. And that traffic barrel? It's actually a camera. That piece of rusted litter? That's a camera too.

Today we are publishing a major update to our zine, "Surveillance Technology at the U.S.-Mexico Border," the first since the second Trump administration began. To help people identify the machinery of homeland security, we've added more models of surveillance towers, newly deployed military tech, and a gallery of disguised trail cams and automated license plate readers.

You can get this 40-page, full-color guide through EFF's Shop or download a Creative-Commons licensed version here.

"The Battalion Search and Rescue always carries the Electronic Frontier Foundation’s zine in our desert rig," says James Holman, who founded the humanitarian group that looks for human remains in remote parts of New Mexico and Arizona. "We’re finding new surveillance all the time, and without a resource like that, we wouldn't know what the hell we're looking at.”

The original version of the zine was distributed nearly exclusively to our allies in the borderlands—journalists, humanitarian aid workers, immigrant advocates—to help them better identify and report on the technology they discover on the ground. We only made a handful available in our online shop, and they went fast.

This time, we've printed enough for our broader EFF membership. Even if you don't live near the border, you can support our work uncovering how the U.S. Department of Homeland Security's technology threatens human rights by picking up a copy.

The zine is the culmination of a dozen trips to the border, where we hunted surveillance towers and other tech installations. We attended multiple border security conventions to collect promotional and technical materials directly from vendors. We filed public records requests, reviewed thousands of pages of docs, and analyzed satellite imagery of the entire 2,000-mile border several times over. Some of the images came from local allies, like geographer Dugan Meyer and Borderlands Relief Collective, who continue to share valuable intelligence on the changing landscape of border surveillance.

The update is available in English, with an updated Spanish version expected later this year. In the meantime, we have reprinted the original Spanish edition.

If you want to know more, a collection of EFF's broader work on border technology is available here. And if you're curious exactly where these technologies are located, you can check our ongoing map.
