Upstream data need to prove soil carbon as a climate solution
Nature Climate Change, Published online: 23 September 2025; doi:10.1038/s41558-025-02429-4
Causal approaches employed at the scale of commercial agriculture are required to build high-quality evidence that climate-smart agricultural interventions result in real emissions reductions and removals. Such project-scale empirical data are additionally required to demonstrate and advance the viability of process-based models and digital measurement, reporting and verification as tools to scale soil carbon accounting.Delayed formation of Arctic snow cover in response to wildland fires in a warming climate
Nature Climate Change, Published online: 23 September 2025; doi:10.1038/s41558-025-02443-6
Wildland fires are becoming more frequent in high-latitude regions. Here the authors show that these fires delay the formation of snow cover in the Arctic, which will be exacerbated under future warming due to increases in burned areas.EFF Statement on TikTok Ownership Deal
One of the reasons we opposed the TikTok "ban" is that the First Amendment is supposed to protect us from government using its power to manipulate speech. But as predicted, the TikTok "ban" has only resulted in turning over the platform to the allies of a president who seems to have no respect for the First Amendment.
TikTok was never proven to be a current national security problem, so it's hard to say the sale will alleviate those unproven concerns. And it remains to be seen if the deal places any limits on the new ownership sharing user data with foreign governments or anyone else—the security concern that purportedly justified the forced sale. As for the algorithm, if the concern had been that TikTok could be a conduit for Chinese government propaganda—a concern the Supreme Court declined to even consider—people can now be concerned that TikTok could be a conduit for U.S. government propaganda. An administration official reportedly has said the new TikTok algorithm will be "retrained" with U.S. data to make sure the system is "behaving properly."
Going Viral vs. Going Dark: Why Extremism Trends and Abortion Content Gets Censored
This is the fourth installment in a blog series documenting EFF's findings from the Stop Censoring Abortion campaign. You can read additional posts here.
One of the goals of our Stop Censoring Abortion campaign was to put names, stories, and numbers to the experiences we’d been hearing about: people and organizations having their abortion-related content – or entire accounts – removed or suppressed on social media. In reviewing survey submissions, we found that multiple users reported experiencing shadowbanning. Shadowbanning (or “deranking”) is widely experienced and reported by content creators across various social media platforms, and it’s a phenomenon that those who create content about abortion and sexual and reproductive health know all too well.
Shadowbanning is the often silent suppression of certain types of content or creators in your social media feeds. It’s not something that a U.S-based creator is notified about, but rather something they simply find out when their posts stop getting the same level of engagement that they’re used to, or when people are unable to easily find their account using the platform’s search function. Essentially, it is when a platform or its algorithm decides that other users should see less of a creator or specific topic. Many platforms deny that shadowbanning exists; they will often blame reduced reach of posts on ‘bugs’ in the algorithm. At the same time, companies like Meta have admitted that content is ranked, but much about how this ranking system works remains unknown. Meta says that there are five content categories that while allowed on its platforms, “may not be eligible for recommendation.” Content discussing abortion pills may fall under the umbrella of “Content that promotes the use of certain regulated products,” but posts that simply affirm abortion as a valid reproductive decision or are of storytellers sharing their experiences don’t match any of the criteria that would make it unable to be recommended by Meta.
Whether a creator relies on a platform for income or uses it to educate the public, shadowbanning can be devastating for the growth of an account. And this practice often seems to disproportionately affect people who are talking about ‘taboo’ topics like sex, abortion, and LGBTQ+ identities, such as Kim Adamski, a sexual health educator who shared her story with our Stop Censoring Abortion project. As you can see in the images below, Kim’s Instagram account does not show up as a suggestion when being searched, and can only be found after typing in the full username.
Earlier this year, the Center for Intimacy Justice shared their report, "The Digital Gag: Suppression of Sexual and Reproductive Health on Meta, TikTok, Amazon, and Google", which found that of the 159 nonprofits, content creators, sex educators, and businesses surveyed, 63% had content removed on Meta platforms and 55% had content removed on TikTok. This suppression is happening at the same time as platforms continue to allow and elevate videos of violence and gore and extremist hateful content. This pattern is troubling and is only becoming more prevalent as people turn to social media to find the information they need to make decisions about their health.
Reproductive rights and sex education have been under attack across the U.S. for decades. Since the Dobbs v. Jackson decision in 2022, 20 states have banned or limited access to abortion. Meanwhile, 16 states don’t require sex education in public schools to be medically accurate, 19 states have laws that stigmatize LGBTQ+ identities in their sex education curricula, and 17 states specifically stigmatize abortion in their sex education curricula.
In a world that is constantly finding ways to legislate away bodily autonomy and hide queer identities, social media platforms have an opportunity to stand as safe havens for access to community and knowledge.
Online platforms are critical lifelines for people seeking possibly life-saving information about their sexual and reproductive health. We know that when people are unable to find or access the information they need within their communities, they will turn to the internet and social media. This is especially important for abortion-seekers and trans youth living in states where healthcare is being criminalized.
In a world that is constantly finding ways to legislate away bodily autonomy and hide queer identities, social media platforms have an opportunity to stand as safe havens for access to community and knowledge. Limiting access to this information by suppressing the people and organizations who are providing it is an attack on free expression and a profound threat to freedom of information—principles that these platforms claim to uphold. Now more than ever, we must continue to push back against censorship of sexual and reproductive health information so that the internet can still be a place where all voices are heard and where all can learn.

MIT affiliates win AI for Math grants to accelerate mathematical discovery
MIT Department of Mathematics researchers David Roe ’06 and Andrew Sutherland ’90, PhD ’07 are among the inaugural recipients of the Renaissance Philanthropy and XTX Markets’ AI for Math grants.
Four additional MIT alumni — Anshula Gandhi ’19, Viktor Kunčak SM ’01, PhD ’07; Gireeja Ranade ’07; and Damiano Testa PhD ’05 — were also honored for separate projects.
The first 29 winning projects will support mathematicians and researchers at universities and organizations working to develop artificial intelligence systems that help advance mathematical discovery and research across several key tasks.
Roe and Sutherland, along with Chris Birkbeck of the University of East Anglia, will use their grant to boost automated theorem proving by building connections between the L-Functions and Modular Forms Database (LMFDB) and the Lean4 mathematics library (mathlib).
“Automated theorem provers are quite technically involved, but their development is under-resourced,” says Sutherland. With AI technologies such as large language models (LLMs), the barrier to entry for these formal tools is dropping rapidly, making formal verification frameworks accessible to working mathematicians.
Mathlib is a large, community-driven mathematical library for the Lean theorem prover, a formal system that verifies the correctness of every step in a proof. Mathlib currently contains on the order of 105 mathematical results (such as lemmas, propositions, and theorems). The LMFDB, a massive, collaborative online resource that serves as a kind of “encyclopedia” of modern number theory, contains more than 109 concrete statements. Sutherland and Roe are managing editors of the LMFDB.
Roe and Sutherland’s grant will be used for a project that aims to augment both systems, making the LMFDB’s results available within mathlib as assertions that have not yet been formally proved, and providing precise formal definitions of the numerical data stored within the LMFDB. This bridge will benefit both human mathematicians and AI agents, and provide a framework for connecting other mathematical databases to formal theorem-proving systems.
The main obstacles to automating mathematical discovery and proof are the limited amount of formalized math knowledge, the high cost of formalizing complex results, and the gap between what is computationally accessible and what is feasible to formalize.
To address these obstacles, the researchers will use the funding to build tools for accessing the LMFDB from mathlib, making a large database of unformalized mathematical knowledge accessible to a formal proof system. This approach enables proof assistants to identify specific targets for formalization without the need to formalize the entire LMFDB corpus in advance.
“Making a large database of unformalized number-theoretic facts available within mathlib will provide a powerful technique for mathematical discovery, because the set of facts an agent might wish to consider while searching for a theorem or proof is exponentially larger than the set of facts that eventually need to be formalized in actually proving the theorem,” says Roe.
The researchers note that proving new theorems at the frontier of mathematical knowledge often involves steps that rely on a nontrivial computation. For example, Andrew Wiles’ proof of Fermat’s Last Theorem uses what is known as the “3-5 trick” at a crucial point in the proof.
“This trick depends on the fact that the modular curve X_0(15) has only finitely many rational points, and none of those rational points correspond to a semi-stable elliptic curve,” according to Sutherland. “This fact was known well before Wiles’ work, and is easy to verify using computational tools available in modern computer algebra systems, but it is not something one can realistically prove using pencil and paper, nor is it necessarily easy to formalize.”
While formal theorem provers are being connected to computer algebra systems for more efficient verification, tapping into computational outputs in existing mathematical databases offers several other benefits.
Using stored results leverages the thousands of CPU-years of computation time already spent in creating the LMFDB, saving money that would be needed to redo these computations. Having precomputed information available also makes it feasible to search for examples or counterexamples without knowing ahead of time how broad the search can be. In addition, mathematical databases are curated repositories, not simply a random collection of facts.
“The fact that number theorists emphasized the role of the conductor in databases of elliptic curves has already proved to be crucial to one notable mathematical discovery made using machine learning tools: murmurations,” says Sutherland.
“Our next steps are to build a team, engage with both the LMFDB and mathlib communities, start to formalize the definitions that underpin the elliptic curve, number field, and modular form sections of the LMFDB, and make it possible to run LMFDB searches from within mathlib,” says Roe. “If you are an MIT student interested in getting involved, feel free to reach out!”
That Drone in the Sky Could Be Tracking Your Car
Police are using their drones as flying automated license plate readers (ALPRs), airborne police cameras that make it easier than ever for law enforcement to follow you.
"The Flock Safety drone, specifically, are flying LPR cameras as well,” Rahul Sidhu, Vice President of Aviation at Flock Safety, recently told a group of potential law enforcement customers interested in drone-as-first-responder (DFR) programs.
The integration of Flock Safety’s flagship ALPR technology with its Aerodome drone equipment is a police surveillance combo poised to elevate the privacy threats to civilians caused by both of these invasive technologies as drone adoption expands.

The use of DFR programs has grown exponentially. The biggest police technology companies, like Axon, Flock Safety, and Motorola Solutions, are broadening their drone offerings, anticipating that drones could become an important piece of their revenue stream.
Communities must demand restrictions on how local police use drones and ALPRs, let alone a dangerous hybrid of the two. Otherwise, we can soon expect that a drone will fly to any call for service and capture sensitive location information about every car in its flight path, capturing more ALPR data to add to the already too large databases of our movements.
ALPR systems typically rely on cameras that have been fixed along roadways or attached to police vehicles. These cameras capture the image of a vehicle, then use artificial intelligence technology to log the license plate, make, model, color, and other unique identifying information, like dents and bumper stickers. This information is usually stored on the manufacturer’s servers and often made available on nationwide sharing networks to police departments from other states and federal agencies, including Immigration and Customs Enforcement. ALPRs are already used by most of the largest police departments in the country, and Flock Safety also now offers the ability for an agency to turn almost any internet-enabled cameras into an ALPR camera.
ALPRs present a host of problems. ALPR systems vacuum up data—like the make, model, color, and location of vehicles—on people who will never be involved in a crime, used in gridding areas to systematically make a record of when and where vehicles have been. ALPRs routinely make mistakes, causing police to stop the wrong car and terrorize the driver. Officers have abused law enforcement databases in hundreds of cases. Police have used them to track across state lines people seeking legal health procedures. Even when there are laws against sharing data from these tools with other departments, some policing agencies still do.
Drones, meanwhile, give police a view of roofs, backyards, and other fenced areas where cops can’t casually patrol, and their adoption is becoming more common. Companies that sell drones have been helping law enforcement agencies to get certifications from the Federal Aviation Authority (FAA), and recently-implemented changes to the restrictions on flying drones beyond the visual line of sight will make it even easier for police to add this equipment. According to the FAA, since a new DFR waiver process was implemented in May 2025, the FAA has granted more than 410 such waivers, already accounting for almost a third of the approximately 1,400 DFR waivers that have been granted since such programs began in 2018.
Local officials should, of course, be informed that the drones they’re buying are equipped to do such granular surveillance from the sky, but it is not clear that this is happening. While the ALPR feature is available as part of Flock drone acquisitions, some government customers may not realize that to approve a drone from Flock Safety may also mean approving a flying ALPR. And though not every Flock safety drone is currently running the ALPR feature, some departments, like Redondo Beach Police Department, have plans to activate it in the near future.
ALPRs aren’t the only so-called payloads that can be added to a drone. In addition to the high resolution and thermal cameras with which drones can already be equipped, drone manufacturers and police departments have discussed adding cell-site simulators, weapons, microphones, and other equipment. Communities must mobilize now to keep this runaway surveillance technology under tight control.
When EFF posed questions to Flock Safety about the integration of ALPR and its drones, the company declined to comment.
Mapping, storing, and tracking as much personal information as possible—all without warrants—is where automated police surveillance is heading right now. Flock has previously described its desire to connect ALPR scans to additional information on the person who owns the car, meaning that we don’t live far from a time when police may see your vehicle drive by and quickly learn that it’s your car and a host of other details about you.

Details About Chinese Surveillance and Propaganda Companies
Details from leaked documents:
While people often look at China’s Great Firewall as a single, all-powerful government system unique to China, the actual process of developing and maintaining it works the same way as surveillance technology in the West. Geedge collaborates with academic institutions on research and development, adapts its business strategy to fit different clients’ needs, and even repurposes leftover infrastructure from its competitors.
[…]
The parallels with the West are hard to miss. A number of American surveillance and propaganda firms also started as academic projects before they were spun out into startups and grew by chasing government contracts. The difference is that in China, these companies operate with far less transparency. Their work comes to light only when a trove of documents slips onto the internet...
