In the future, autonomous drones could be used to shuttle inventory between large warehouses. A drone might fly into a semi-dark structure the size of several football fields, zipping along hundreds of identical aisles before docking at the precise spot where its shipment is needed.

Most of today’s drones would likely struggle to complete this task, since drones typically navigate outdoors using GPS, which doesn’t work in indoor environments. For indoor navigation, some drones employ computer vision or lidar, but both techniques are unreliable in dark environments or rooms with plain walls or repetitive features.

MIT researchers have introduced a new approach that enables a drone to self-localize, or determine its position, in indoor, dark, and low-visibility environments. Self-localization is a key step in autonomous navigation.

The researchers developed a system called MiFly, in which a drone uses radio frequency (RF) waves, reflected by a single tag placed in its environment, to autonomously self-localize.

Because MiFly enables self-localization with only one small tag, which could be affixed to a wall like a sticker, it would be cheaper and easier to implement than systems that require multiple tags. In addition, since the MiFly tag reflects signals sent by the drone, rather than generating its own signal, it can be operated with very low power.

Two off-the-shelf radars mounted on the drone enable it to localize in relation to the tag. Those measurements are fused with data from the drone’s onboard computer, which enables it to estimate its trajectory.

The researchers conducted hundreds of flight experiments with real drones in indoor environments, and found that MiFly consistently localized the drone to within fewer than 7 centimeters.

“As our understanding of perception and computing improves, we often forget about signals that are beyond the visible spectrum. Here, we’ve looked beyond GPS and computer vision to millimeter waves, and by doing so, we’ve opened up new capabilities for drones in indoor environments that were not possible before,” says Fadel Adib, associate professor in the Department of Electrical Engineering and Computer Science, director of the Signal Kinetics group in the MIT Media Lab, and senior author of a paper on MiFly.

Adib is joined on the paper by co-lead authors and research assistants Maisy Lam and Laura Dodds; Aline Eid, a former postdoc who is now an assistant professor at the University of Michigan; and Jimmy Hester, CTO and co-founder of Atheraxon, Inc. The research will be presented at the IEEE Conference on Computer Communications.

Backscattered signals

To enable drones to self-localize within dark, indoor environments, the researchers decided to utilize millimeter wave signals. Millimeter waves, which are commonly used in modern radars and 5G communication systems, work in the dark and can travel through everyday materials like cardboard, plastic, and interior walls.

They set out to create a system that could work with just one tag, so it would be cheaper and easier to implement in commercial environments. To ensure the device remained low power, they designed a backscatter tag that reflects millimeter wave signals sent by a drone’s onboard radar. The drone uses those reflections to self-localize.

But the drone’s radar would receive signals reflected from all over the environment, not just the tag. The researchers surmounted this challenge by employing a technique called modulation. They configured the tag to add a small frequency to the signal it scatters back to the drone.

“Now, the reflections from the surrounding environment come back at one frequency, but the reflections from the tag come back at a different frequency. This allows us to separate the responses and just look at the response from the tag,” Dodds says.

However, with just one tag and one radar, the researchers could only calculate distance measurements. They needed multiple signals to compute the drone’s location.

Rather than using more tags, they added a second radar to the drone, mounting one horizontally and one vertically. The horizontal radar has a horizontal polarization, which means it sends signals horizontally, while the vertical radar would have a vertical polarization.

They incorporated polarization into the tag’s antennas so it could isolate the separate signals sent by each radar.

“Polarized sunglasses receive a certain polarization of light and block out other polarizations. We applied the same concept to millimeter waves,” Lam explains.

In addition, they applied different modulation frequencies to the vertical and horizontal signals, further reducing interference.

Precise location estimation

This dual-polarization and dual-modulation architecture gives the drone’s spatial location. But drones also move at an angle and rotate, so to enable a drone to navigate, it must estimate its position in space with respect to six degrees of freedom — with trajectory data including pitch, yaw, and roll in addition to the usual forward/backward, left/right, and up/down.

“The drone rotation adds a lot of ambiguity to the millimeter wave estimates. This is a big problem because drones rotate quite a bit as they are flying,” Dodds says.

They overcame these challenges by utilizing the drone’s onboard inertial measurement unit, a sensor that measures acceleration as well as changes in altitude and attitude. By fusing this information with the millimeter wave measurements reflected by the tag, they enable MiFly to estimate the full six-degree-of-freedom pose of the drone in only a few milliseconds.

They tested a MiFly-equipped drone in several indoor environments, including their lab, the flight space at MIT, and the dim tunnels beneath the campus buildings. The system achieved high accuracy consistently across all environments, localizing the drone to within 7 centimeters in many experiments.

In addition, the system was nearly as accurate in situations where the tag was blocked from the drone’s view. They achieved reliable localization estimates up to 6 meters from the tag.

That distance could be extended in the future with the use of additional hardware, such as high-power amplifiers, or by improving the radar and antenna design. The researchers also plan to conduct further research by incorporating MiFly into an autonomous navigation system. This could enable a drone to decide where to fly and execute a flight path using millimeter wave technology.

“The infrastructure and localization algorithms we build up for this work are a strong foundation to go on and make them more robust to enable diverse commercial applications,” Lam says.

The core of a massive cluster of galaxies appears to be pumping out far more stars than it should. Now researchers at MIT and elsewhere have discovered a key ingredient within the cluster that explains the core’s prolific starburst.

In a new study published in Nature, the scientists report using NASA’s James Webb Space Telescope (JWST) to observe the Phoenix cluster — a sprawling collection of gravitationally bound galaxies that circle a central massive galaxy some 5.8 billion light years from Earth. The cluster is the largest of its kind that scientists have so far observed. For its size and estimated age, the Phoenix should be what astronomers call “red and dead” — long done with any star formation that is characteristic of younger galaxies.

But astronomers previously discovered that the core of the Phoenix cluster appeared surprisingly bright, and the central galaxy seemed to be churning out stars at an extremely vigorous rate. The observations raised a mystery: How was the Phoenix fueling such rapid star formation?

In younger galaxies, the “fuel” for forging stars is in the form of extremely cold and dense clouds of interstellar gas. For the much older Phoenix cluster, it was unclear whether the central galaxy could undergo the extreme cooling of gas that would be required to explain its stellar production, or whether cold gas migrated in from other, younger galaxies.

Now, the MIT team has gained a much clearer view of the cluster’s core, using JWST’s far-reaching, infrared-measuring capabilities. For the first time, they have been able to map regions within the core where there are pockets of “warm” gas. Astronomers have previously seen hints of both very hot gas, and very cold gas, but nothing in between.

The detection of warm gas confirms that the Phoenix cluster is actively cooling and able to generate a huge amount of stellar fuel on its own.

“For the first time we have a complete picture of the hot-to-warm-to-cold phase in star formation, which has really never been observed in any galaxy,” says study lead author Michael Reefe, a physics graduate student in MIT’s Kavli Institute for Astrophysics and Space Research. “There is a halo of this intermediate gas everywhere that we can see.”

“The question now is, why this system?” adds co-author Michael McDonald, associate professor of physics at MIT. “This huge starburst could be something every cluster goes through at some point, but we’re only seeing it happen currently in one cluster. The other possibility is that there’s something divergent about this system, and the Phoenix went down a path that other systems don’t go. That would be interesting to explore.”

Hot and cold

The Phoenix cluster was first spotted in 2010 by astronomers using the South Pole Telescope in Antarctica. The cluster comprises about 1,000 galaxies and lies in the constellation Phoenix, after which it is named. Two years later, McDonald led an effort to focus in on Phoenix using multiple telescopes, and discovered that the cluster’s central galaxy was extremely bright. The unexpected luminosity was due to a firehose of star formation. He and his colleagues estimated that this central galaxy was turning out stars at a staggering rate of about 1,000 per year.

“Previous to the Phoenix, the most star-forming galaxy cluster in the universe had about 100 stars per year, and even that was an outlier. The typical number is one-ish,” McDonald says. “The Phoenix is really offset from the rest of the population.”

Since that discovery, scientists have checked in on the cluster from time to time for clues to explain the abnormally high stellar production. They have observed pockets of both ultrahot gas, of about 1 million degrees Fahrenheit, and regions of extremely cold gas, of 10 kelvins, or 10 degrees above absolute zero.

The presence of very hot gas is no surprise: Most massive galaxies, young and old, host black holes at their cores that emit jets of extremely energetic particles that can continually heat up the galaxy’s gas and dust throughout a galaxy’s lifetime. Only in a galaxy’s early stages does some of this million-degree gas cool dramatically to ultracold temperatures that can then form stars. For the Phoenix cluster’s central galaxy, which should be well past the stage of extreme cooling, the presence of ultracold gas presented a puzzle.

“The question has been: Where did this cold gas come from?” McDonald says. “It’s not a given that hot gas will ever cool, because there could be black hole or supernova feedback. So, there are a few viable options, the simplest being that this cold gas was flung into the center from other nearby galaxies. The other is that this gas somehow is directly cooling from the hot gas in the core.”

Neon signs

For their new study, the researchers worked under a key assumption: If the Phoenix cluster’s cold, star-forming gas is coming from within the central galaxy, rather than from the surrounding galaxies, the central galaxy should have not only pockets of hot and cold gas, but also gas that’s in a “warm” in-between phase. Detecting such intermediate gas would be like catching the gas in the midst of extreme cooling, serving as proof that the core of the cluster was indeed the source of the cold stellar fuel.

Following this reasoning, the team sought to detect any warm gas within the Phoenix core. They looked for gas that was somewhere between 10 kelvins and 1 million kelvins. To search for this Goldilocks gas in a system that is 5.8 billion light years away, the researchers looked to JWST, which is capable of observing farther and more clearly than any observatory to date.

The team used the Medium-Resolution Spectrometer on JWST’s Mid-Infrared Instrument (MIRI), which enables scientists to map light in the infrared spectrum. In July of 2023, the team focused the instrument on the Phoenix core and collected 12 hours’ worth of infrared images. They looked for a specific wavelength that is emitted when gas — specifically neon gas — undergoes a certain loss of ions. This transition occurs at around 300,000 kelvins, or 540,000 degrees Fahrenheit — a temperature that happens to be within the “warm” range that the researchers looked to detect and map. The team analyzed the images and mapped the locations where warm gas was observed within the central galaxy.

“This 300,000-degree gas is like a neon sign that’s glowing in a specific wavelength of light, and we could see clumps and filaments of it throughout our entire field of view,” Reefe says. “You could see it everywhere.”

Based on the extent of warm gas in the core, the team estimates that the central galaxy is undergoing a huge degree of extreme cooling and is generating an amount of ultracold gas each year that is equal to the mass of about 20,000 suns. With that kind of stellar fuel supply, the team says it’s very likely that the central galaxy is indeed generating its own starburst, rather than using fuel from surrounding galaxies.

“I think we understand pretty completely what is going on, in terms of what is generating all these stars,” McDonald says. “We don’t understand why. But this new work has opened a new way to observe these systems and understand them better.”

The Haber-Bosch process, which converts atmospheric nitrogen to make ammonia fertilizer, revolutionized agriculture and helped feed the world’s growing population, but it also created huge environmental problems. It is one of the most energy-intensive chemical processes in the world, responsible for 1-2 percent of global energy consumption. It also releases nitrous oxide, a potent greenhouse gas that harms the ozone layer. Excess nitrogen also routinely runs off farms into waterways, harming marine life and polluting groundwater.

In place of synthetic fertilizer, Pivot Bio has engineered nitrogen-producing microbes to make farming more sustainable. The company, which was co-founded by Professor Chris Voigt, Karsten Temme, and Alvin Tamsir, has engineered its microbes to grow on plant roots, where they feed on the root’s sugars and precisely deliver nitrogen in return.

Pivot’s microbial colonies grow with the plant and produce more nitrogen at exactly the time the plant needs it, minimizing nitrogen runoff.

“The way we have delivered nutrients to support plant growth historically is fertilizer, but that’s an inefficient way to get all the nutrients you need,” says Temme, Pivot’s chief innovation officer. “We have the ability now to help farmers be more efficient and productive with microbes.”

Farmers can replace up to 40 pounds per acre of traditional nitrogen with Pivot’s product, which amounts to about a quarter of the total nitrogen needed for a crop like corn.

Pivot’s products are already being used to grow corn, wheat, barley, oats, and other grains across millions of acres of American farmland, eliminating hundreds of thousands of tons of CO2 equivalent in the process. The company’s impact is even more striking given its unlikely origins, which trace back to one of the most challenging times of Voigt’s career.

A Pivot from despair

The beginning of every faculty member’s career can be a sink-or-swim moment, and by Voigt’s own account, he was drowning. As a freshly minted assistant professor at the University of California at San Francisco, Voigt was struggling to stand up his lab, attract funding, and get experiments started.

Around 2008, Voigt joined a research group out of the University of California at Berkeley that was writing a grant proposal focused on photovoltaic materials. His initial role was minor, but a senior researcher pulled out of the group a week before the proposal had to be submitted, so Voigt stepped up.

“I said ‘I’ll finish this section in a week,’” Voigt recalls. “It was my big chance.”

For the proposal, Voigt detailed an ambitious plan to rearrange the genetics of biologic photosynthetic systems to make them more efficient. He barely submitted it in time.

A few months went by, then the proposal reviews finally came back. Voigt hurried to the meeting with some of the most senior researchers at UC Berkeley to discuss the responses.

“My part of the proposal got completely slammed,” Voigt says. “There were something like 15 reviews on it — they were longer than the actual grant — and it’s just one after another tearing into my proposal. All the most famous people are in this meeting, future energy secretaries, future leaders of the university, and it was totally embarrassing. After that meeting, I was considering leaving academia.”

A few discouraging months later, Voigt got a call from Paul Ludden, the dean of the School of Science at UC Berkeley. He wanted to talk.

“As I walk into Paul’s office, he’s reading my proposal,” Voigt recalls. “He sits me down and says, ‘Everybody’s telling me how terrible this is.’ I’m thinking, ‘Oh my God.’ But then he says, ‘I think there’s something here. Your idea is good, you just picked the wrong system.’”

Ludden went on to explain to Voigt that he should apply his gene-swapping idea to nitrogen fixation. He even offered to send Voigt a postdoc from his lab, Dehua Zhao, to help. Voigt paired Zhao with Temme, and sure enough, the resulting 2011 paper of their work was well-received by the nitrogen fixation community.

“Nitrogen fixation has been a holy grail for scientists, agronomists, and farmers for almost a century, ever since somebody discovered the first microbe that can fix nitrogen for legumes like soybeans,” Temme says. “Everybody always said that someday we'll be able to do this for the cereal crops. The excitement with Pivot was this is the first time that technology became accessible.”

Voigt had moved to MIT in 2010. When the paper came out, he founded Pivot Bio with Temme and another Berkeley researcher, Alvin Tamsir. Since then, Voigt, who is the Daniel I.C. Wang Professor at MIT and the head of the Department of Biological Engineering, has continued collaborating with Pivot on things like increasing nitrogen production, making strains more stable, and making them inducible to different signals from the plant. Pivot has licensed technology from MIT, and the research has also received support from MIT’s Abdul Latif Jameel Water and Food Systems Lab (J-WAFS).

Pivot’s first goals were to gain regulatory approval and prove themselves in the marketplace. To gain approval in the U.S., Pivot’s team focused on using DNA from within the same organism rather than bringing in totally new DNA, which simplified the approval process. It also partnered with independent corn seed dealers to get its product to farms. Early deployments occurred in 2019.

Farmers apply Pivot’s product at planting, either as a liquid that gets sprayed on the soil or as a dry powder that is rehydrated and applied to the seeds as a coating. The microbes live on the surface of the growing root system, eating plant sugars and releasing nitrogen throughout the plant’s life cycle.

“Today, our microbes colonize just a fraction of the total sugars provided by the plant,” Temme explains. “They’re also sharing ammonia with the plant, and all of those things are just a portion of what’s possible technically. Our team is always trying to figure out how to make those microbes more efficient at getting the energy they need to grow or at fixing nitrogen and sharing it with the crop.”

In 2023, Pivot started the N-Ovator program to connect companies with growers who practice sustainable farming using Pivot’s microbial nitrogen. Through the program, companies buy nitrogen credits and farmers can get paid by verifying their practices. The program was named one of the Inventions of the Year by Time Magazine last year and has paid out millions of dollars to farmers to date.

Microbial nitrogen and beyond

Pivot is currently selling to farmers across the U.S. and working with smallholder farmers in Kenya. It’s also hoping to gain approval for its microbial solution in Brazil and Canada, which it hopes will be its next markets.

"How do we get the economics to make sense for everybody — the farmers, our partners, and the company?” Temme says of Pivot’s mission. “Because this truly can be a deflationary technology that upends the very expensive traditional way of making fertilizer.”

Pivot’s team is also extending the product to cotton, and Temme says microbes can be a nitrogen source for any type of plant on the planet. Further down the line, the company believes it can help farmers with other nutrients essential to help their crops grow.

“Now that we’ve established our technology, how can Pivot help farmers overcome all the other limitations they face with crop nutrients to maximize yields?” Temme asks. “That really starts to change the way a farmer thinks about managing the entire acre from a price, productivity, and sustainability perspective.”

Satellite observations suggest a slowdown in the decay of sea surface temperature anomalies over the past four decades, coinciding with an increase in the duration of marine heatwaves. This change is probably linked to factors such as stronger upper-ocean stratification, a deepening mixed layer and weakening oceanic forcing.

This study uses available models to show intensified Atlantic multidecadal variability under global warming. Warmer and fresher waters, along with slowed overturning circulation, reduce the mixed layer, intensifying sea surface temperature variability, suggesting increased global climate extremes.

“Intelligent, caring, inspiring, and full-of-wisdom,” one student described Kenneth Oye. Another lauded that “We are beyond lucky to have such a caring, supportive, empathetic and compassionate leader” in Maria Yang.

Professors Maria Yang and Kenneth Oye are two of the 2023-25 Committed to Caring cohort, acknowledged for encouraging their students; advocating for meaningful, interesting research; and participating in their research journey from the beginning to end. For MIT graduate students, the Committed to Caring program recognizes those who go above and beyond.

Maria Yang: Inclusion and continual fostering

Professor Maria Yang is the deputy dean of engineering, Kendall Rohsenow Professor, and professor of mechanical engineering. She works in the area of design theory, with a focus on the early stages of the process of design. Her current research interests include the hybrid ways in which humans and AI can collaborate during the design process and also ways in which we can design products to encourage users to behave more sustainably.

Yang has been selected as a recipient of the Committed to Caring award for 2023-25. She is known for her inclusive, interdisciplinary work as well as her continuous fostering of students.

Yang founded and leads the Ideation Laboratory at MIT, which is characterized by interdisciplinary work in design, including product design, engineering design, and system design. Students may not feel like they “fit” in their traditional department, but find a home in the Ideation Laboratory. In Yang’s words, her students “collaborate and connect from their shared experiences.”

Yang is one of the mentors of a student-led research project that works toward understanding how users, and other stakeholders who are traditionally not considered, are embedded in design education and practice, and how to support deeper engagement with such users and stakeholders. Yang supported her students on this project in multiple ways, providing mentorship and feedback as well as supporting her students to apply for grants to continue growing the project.

The students and Yang held a first-ever summit as a part of this project. The summit brought together faculty and students from MIT as well as other universities and companies. All the summit stakeholders are working to support instructors in thoughtfully considering users and stakeholders in their courses, and are striving to create a community for students and instructors engaged in this space.

“Maria will never take credit for the outcomes of the project, giving all the credit to other members of the project team,” the nominator wrote, “but she has been instrumental in supporting us and encouraging us to continue.”

Yang continued to be a supportive and caring mentor, championing and supporting students’ work. When one nominator was still a prospective student, Yang met with them in support of their application. When the student was eventually admitted into the Media Lab rather than mechanical engineering, Yang welcomed the student into her research group.

As the student’s career evolved, Yang became a member of their thesis committee and provided letters of recommendation for their academic job search. The nominator turned to Maria for advice on how to strategize what applications they would submit and which departments were the best fit for them.

Yang took time to sit with the student, practiced their presentation with them, and gave support where the student was lacking confidence. All in all, Yang helped them have the strength to continue to achieve their goals, ultimately enabling them to earn their PhD.

The nominator was grateful for the crucial role Maria played in fostering their growth: “My MIT experience would have been very different without Maria.”

Kenneth Oye: Inspiring advisor and caring mentor

Oye is a professor of political science and data systems and society as well as the director of the Program on Emerging Technologies (PoET). His work revolves around international relations, political economy, and technology policy. His current work in technology policy centers on adaptive management of risks associated with synthetic biology and pharmaceuticals and on equity in health policy.

Oye has been selected as a recipient of the Committed to Caring award for 2023-25. He is a highly effective instructor, influential advisor, and considerate mentor.

Oye teaches with clear and easy-to-follow language filled with personal stories and rich experiences. His lectures are interactive and engaging so that learners can truly internalize the material. His students gain understanding with curiosity and intent.

A nominator wrote that Oye encourages his students to investigate broadly. Oye offers frequent advice on improvements in research design and shared analysis techniques. “He acknowledged my effort and ideas,” the nominator shared, “but also always encouraged me to explore further.”

The student added that parts of their dissertation were challenging, but Oye transformed it into an enjoyable intellectual quest.

Oye emphasized that he cares about the work that is produced; however, he equally attends to his students as individuals. He consistently starts weekly meetings with check-ins and concerns himself with each of his student’s well-being and personal development.

Students feel comfortable coming to Oye when they need to share their strife and seek counsel. Their mentoring relationship had built such trust, one nominator remarked, that when the student faced some personal challenges, “Ken was the first person I thought of that I could share my struggles with safely and ask for advice.”

As an instructor, an advisor, and as a mentor, Oye has helped his students learn and grow beyond the classroom.

One of his students wrote, “Oye’s truly a gem to learn from and work with, and I believe he has been a great asset to MIT’s generations of students.”

Across the United States, Immigration and Customs Enforcement (ICE) has already begun increasing enforcement operations, including highly publicized raids. As immigrant communities, families, allies, and activists think about what can be done to shift policy and protect people, one thing is certain: similar to filming the police as they operate, you have the right to film ICE, as long as you are not obstructing official duties.

Filming ICE agents making an arrest or amassing in your town helps promote transparency and accountability for a system that often relies on intimidation and secrecy and obscures abuse and law-breaking. 

While it is crucial for people to help aid in transparency and accountability, there are considerations and precautions you should take. For an in-depth guide by organizations on the frontlines of informing people who wish to record ICE’s interactions with the public, review these handy resources from the hard-working folks at WITNESS and NYCLU. 

At EFF, here are our general guidelines when it comes to filming law enforcement, including ICE: 

What to Know When Recording Law Enforcement

• You have the right to record law enforcement officers exercising their official duties in public.
• Stay calm and courteous.
• Do not interfere with law enforcement. If you are a bystander, stand at a safe distance from the scene that you are recording.
• You may take photos or record video and/or audio.
• Law enforcement cannot order you to move because you are recording, but they may order you to move for public safety reasons even if you are recording.
• Law enforcement may not search your cell phone or other device without a warrant based on probable cause from a judge, even if you are under arrest. Thus, you may refuse a request from an officer to review or delete what you recorded. You also may refuse to unlock your phone or provide your passcode.
• Despite reasonably exercising your First Amendment rights, law enforcement officers may illegally retaliate against you in a number of ways including with arrest, destruction of your device, and bodily harm. They may also try to retaliate by harming the person being arrested. We urge you to remain alert and mindful about this possibility.
• Consider the sensitive nature of recording in the context of an ICE arrest. The person being arrested or their loved ones may be concerned about exposing their immigration status, so think about obtaining consent or blurring out faces in any version you publish to focus on ICE’s conduct (while still retaining the original video).

Your First Amendment Right to Record Law Enforcement Officers Exercising Their Official Duties in Public

You have a First Amendment right to record law enforcement, which federal courts and the Justice Department have recognized and affirmed. Although the Supreme Court has not squarely ruled on the issue, there is a long line of First Amendment case law from the high court that supports the right to record law enforcement. And federal appellate courts in the First, Third, Fourth, Fifth, Seventh, Eighth, Ninth, Tenth, and Eleventh Circuits have directly upheld this right. EFF has advocated for this right in many amicus briefs.

Federal appellate courts typically frame the right to record law enforcement as the right to record officers exercising their official duties in public. This right extends to private places, too, where the recorder has a legal right to be, such as in their own home. However, if the law enforcement officer is off-duty or is in a private space that you don’t have a right to be in, your right to record the officer may be limited. 

Special Considerations for Recording Audio

The right to record law enforcement unequivocally includes the right to take pictures and record video. There is an added legal wrinkle when recording audio—whether with or without video. Some law enforcement officers have argued that recording audio without their consent violates wiretap laws. Courts have generally rejected this argument. The Seventh Circuit, for example, held that the Illinois wiretap statute violated the First Amendment as applied to audio recording on-duty police.

There are two kinds of wiretaps laws: those that require “all parties” to a conversation to consent to audio recording (12 states), and those that only require “one party” to consent (38 states, the District of Columbia, and the federal statute). Thus, if you’re in a one-party consent state, and you’re involved in an incident with law enforcement (that is, you’re a party to the conversation) and you want to record audio of that interaction, you are the one party consenting to the recording and you don’t also need the law enforcement officer’s consent. If you’re in an all-party consent state, and your cell phone or recording device is in plain view, your open audio recording puts the officer on notice and thus their consent might be implied.

Additionally, wiretap laws in both all-party consent states and one-party consent states typically only prohibit audio recording of private conversations—that is, when the parties to the conversation have a reasonable expectation of privacy. Law enforcement officers exercising their official duties, particularly in public, do not have a reasonable expectation of privacy. Neither do civilians in public places who speak to law enforcement in a manner audible to passersby. Thus, if you’re a bystander, you may legally audio record an officer’s interaction with another person, regardless of whether you’re in a state with an all-party or one-party consent wiretap statute. However, you should take into consideration that ICE arrests may expose the immigration status of the person being arrested or their loved ones. As WITNESS puts it: “[I]t’s important to keep in mind the privacy and dignity of the person being targeted by law enforcement. They may not want to be recorded or have the video shared publicly. When possible, make eye contact or communicate with the person being detained to let them know that you are there to observe and document the cops’ behavior. Always respect their wishes if they ask you to stop filming.” You may also want to consider blurring faces to focus on ICE’s conduct if you publish the video online (while still retaining the original version)

Moreover, whether you may secretly record law enforcement (whether with photos, video or audio) is important to understand, given that officers may retaliate against individuals who openly record them. At least one federal appellate court, the First Circuit, has affirmed the First Amendment right to secretly audio record law enforcement performing their official duties in public. On the other hand, the Ninth Circuit recently upheld Oregon’s law that generally bans secret recordings of in-person conversations without all participants’ consent, and only allows recordings of conversations where police officers are participants if “[t]he recording is made openly and in plain view of the participants in the conversation.” Unless you are within the jurisdiction of the First Circuit (Maine, Massachusetts, New Hampshire, Puerto Rico and Rhode Island), it’s probably best to have your recording device in plain view of police officers.

Do Not Interfere With Law Enforcement

While the weight of legal authority provides that individuals have a First Amendment right to record law enforcement, courts have also stated one important caveat: you may not interfere with officers doing their jobs.

The Seventh Circuit, for example, said, “Nothing we have said here immunizes behavior that obstructs or interferes with effective law enforcement or the protection of public safety.” The court further stated, “While an officer surely cannot issue a ‘move on’ order to a person because he is recording, the police may order bystanders to disperse for reasons related to public safety and order and other legitimate law enforcement needs.”

Transparency is Vital

While a large number of deportations is a constant in the U.S. regardless of who is president or which party is in power, the current administration appears to be intentionally making ICE visible in cities and carrying out flashy raids to sow fear within immigrant communities. Specifically, there are concerns that this administration is targeting people already under government supervision while awaiting their day in court. Bearing witness and documenting the presence and actions of ICE in your communities and neighborhoods is important. You have rights, and one of them is your First Amendment-protected right to film law enforcement officers, including ICE agents.

Just because you have the right, however, does not mean law enforcement will always acknowledge and uphold your right in that moment. Be safe and be alert. If you have reason to think your devices might be seized or you may run the risk of putting yourself under surveillance, make sure to check out our Surveillance Self-Defense guides and our field guide to identifying and understanding the surveillance tools law enforcement may employ.

For years now, there has been some concern about the coziness between technology companies and the government. Whether a company complies with casual government requests for data, requires a warrant, or even fights overly-broad warrants has been a canary in the digital coal mine during an era where companies may know more about you than your best friends and families. For example, in 2022, law enforcement served a warrant to Facebook for the messages of a 17-year-old girl—messages that were later used as evidence in a criminal trial that the teenager had received an abortion. In 2023, after a four year wait since announcing its plans, Facebook encrypted its messaging system so that the company no longer had access to the content of those communications.

The privacy of messages and the relationship between companies and the government have real-world consequences. That is why a new era of symbiosis between big tech companies and the U.S. government bodes poorly for both, our hopes that companies will be critical of requests for data, and any chance of tech regulations and consumer privacy legislation. But, this chumminess should also come with a heightened awareness for users: as companies and the government become more entwined through CEO friendships, bureaucratic entanglements, and ideological harmony, we should all be asking what online data is private and what is sitting on a company's servers and accessible to corporate leadership at the drop of hat.

Over many years, EFF has been pushing for users to switch to platforms that understand the value of encrypting data. We have also been pushing platforms to make end-to-end encryption for online communications and for your stored sensitive data the norm. This type of encryption helps ensure that a conversation is private between you and the recipient, and not accessible to the platform that runs it or any other third-parties. Thanks to the combined efforts of our organization and dozens of other concerned groups, tech users, and public officials, we now have a lot of options for applications and platforms that take our privacy more seriously than in previous generations. But, in light of recent political developments it’s time for a refresher course: which platforms and applications have encrypted DMs, and which have access to your sensitive personal communications.

The existence of what a platform calls “end-to-end encryption” is not foolproof. It may be poorly implemented, lack widespread adoption to attract the attention of security researchers, lack the funding to pay for security audits, or use a less well-established encryption protocol that doesn’t have much public scrutiny. It also can’t protect against other sorts of threats, like someone gaining access to your device or screenshotting a conversation. Being caught using certain apps can itself be dangerous in some cases. And it takes more than just a basic implementation to resist a targeted active attack, as opposed to later collection. But it’s still the best way we currently have to ensure our digital conversations are as private as possible. And more than anything, it needs to be something you and the people you speak with will actually use, so features can be an important consideration.

No platform provides a perfect mix of security features for everyone, but understanding the options can help you start figuring out the right choices. When it comes to popular social media platforms, Facebook Messenger uses end-to-end encryption on private chats by default (this feature is optional in group chats on Messenger, and on some of the company’s other offerings, like Instagram). Other companies, like X, offer optional end-to-end encryption, with caveats, such as only being available to users who pay for verification. Then there’s platforms like Snapchat, which have given talks about their end-to-end encryption in the past, but don’t provide further details about its current implementations. Other platforms, like Bluesky, Mastodon, and TikTok, do not offer end-to-end encryption in direct messages, which means those conversations could be accessible to the companies that run the platforms or made available to law enforcement upon request.

As for apps more specifically designed around chat, there are more examples. Signal offers end-to-end encryption for text messages and voice calls by default with no extra setup on your part, and collects less metadata than other options. Metadata can reveal information such as who you are talking with and when, or your location, which in some cases may be all law enforcement needs. WhatsApp is also end-to-end encrypted. Apple’s Messages app is end-to-end encrypted, but only if everyone in the chat has an iPhone (blue bubbles). The same goes for Google Messages, which is end-to-end encrypted as long as everyone has set it up properly, which sometimes happens automatically.

Of course, we have a number of other communication tools at our disposal, like Zoom, Slack, Discord, Telegram, and more. Here, things continue to get complicated, with end-to-end encryption being an optional feature sometimes, like on Zoom or Telegram; available only for specific types of communication, like video and voice calls on Discord but not text conversations; or not being available at all, like with Slack. Many other options exist with varying feature-sets, so it’s always worth doing some research if you find something new. This does not mean you need to avoid these tools entirely, but knowing that your chats may be available to the platform, law enforcement, or an administrator is an important thing to consider when choosing what to say and when to say it. 

And for high-risk users, the story becomes even more complicated. Even on an encrypted platform, users can be subject to targeted machine-in-the middle attacks (also known as man-in-the middle attacks) unless everyone verifies each others’ keys. Most encrypted apps will let you do this manually, but some have started to implement automatic key verification, which is a security win. And encryption doesn’t matter if message backups are uploaded to the company’s servers unencrypted, so it’s important to either choose to not backup messages, or carefully set up encrypted backups on platforms that allow it. This is all before getting into the intricacies of how apps handle deleted and disappearing messages, or whether there’s a risk of being found with an encrypted app in the first place.

CEOs are not the beginning and the end of a company’s culture and concerns—but we should take their commitments and signaled priorities seriously. At a time when some companies may be cozying up to the parts of government with the power to surveil and marginalize, it might be an important choice to move our data and sensitive communications to different platforms. After all, even if you are not at specific risk of being targeted by the government, your removed participation on a platform sends a clear political message about what you value in a company. 

Here’s a supply-chain attack just waiting to happen. A group of researchers searched for, and then registered, abandoned Amazon S3 buckets for about $400. These buckets contained software libraries that are still used. Presumably the projects don’t realize that they have been abandoned, and still ping them for patches, updates, and etc.

The TL;DR is that this time, we ended up discovering ~150 Amazon S3 buckets that had previously been used across commercial and open source software products, governments, and infrastructure deployment/update pipelines—and then abandoned...
