The lawsuit represents the latest salvo in a battle with the Trump administration over the agency's Greenhouse Gas Reduction Fund.

The state will remain out of the regional carbon-trading program, pending appeal of a finding that the state's withdrawal was illegal.

Analysis shows the oil giant sharply increased its use of carbon credits to offset its emissions as the voluntary market faced criticism.

Twelve years ago, the states agreed to collectively promote electric vehicles. Supporters say their success shows the power of state-level rules and incentives.

A proposal to delay rules aimed at boosting electric truck sales is the latest sign of Democratic lawmakers’ growing discomfort over implementing a landmark climate law.

The council said Switzerland “had failed to comply with its duties” to combat climate change and meet emissions targets.

A member of the European Parliament argued that “the program provides insufficient financial control and accountability" for nongovernmental organizations.

“Butterflies have been declining the last 20 years,” a study co-author said. “And we don't see any sign that that’s going to end.”

Last month saw digital rights organizations and social justice groups head to Taiwan for this year's RightsCon conference on human rights in the digital age. During the conference, one prominent message was spoken loud and clear: Alaa Abd El-Fattah must be immediately released from illegal detention in Egypt.

"As Alaa’s mother, I thank you for your solidarity and ask you to not to give up until Alaa is out of prison."

During the RightsCon opening ceremony, Access Now’s Executive Director, Alejandro Mayoral Baños, affirmed the urgency of Alaa’s situation in detention and called for Alaa’s freedom. The RightsCon community was also addressed by Alaa’s mother, mathematician Laila Soueif, who has been on hunger strike in London for 158 days. In a video highlighting Alaa’s work with digital rights and his role in this community, she stated: “As Alaa’s mother, I thank you for your solidarity and ask you to not to give up until Alaa is out of prison.” Laila was admitted to hospital the next day with dangerously low blood sugar, blood pressure and sodium levels.

The calls to #FreeAlaa and save Laila were again reaffirmed during the closing ceremony in a keynote by Sara Alsherif, Migrant Digital Justice Programme Manager at Open Rights Group and close friend of Alaa. Referencing Alaa’s early work as a digital activist, Alsherif said: “He understood that the fight for digital rights is at the core of the struggle for human rights and democracy.” She closed by reminding the hundreds-strong audience that “Alaa could be any one of us … Please do for him what you would want us to do for you if you were in his position.”

During RightsCon, with Laila still in hospital, calls for UK Prime Minister Starmer to get on the phone with Egyptian President Sisi reached a fever pitch, and on 28 February, one day after the closing ceremony, the UK government issued a press release affirming that Alaa’s case had been discussed, with Starmer pressing for Alaa’s freedom. 

Alaa should have been released on September 29, after serving a five-year sentence for sharing a Facebook post about a death in police custody, but Egyptian authorities have continued his imprisonment in contravention of the country’s own Criminal Procedure Code. British consular officials are prevented from visiting him in prison because the Egyptian government refuses to recognise Alaa’s British citizenship.

Laila Soueif has been on hunger strike for more than five months while she and the rest of his family have worked in concert with various advocacy groups to engage the British government in securing Alaa’s release. On December 12, she also started protesting daily outside the Foreign Office and has since been joined by numerous MPs and public figures. Laila still remains in hospital, but following Starmer’s call with Sisi agreed to take glucose, she stated that she is ready to end her hunger strike if progress is made.

As of March 6, Laila has moved to a partial hunger strike of 300 calories per day citing “hope that Alaa’s case might move.” However, the family has learned that Alaa himself began a hunger strike on March 1 in prison after hearing that his mother had been hospitalized. Laila has said that without fast movement on Alaa’s case she will return to a total hunger strike. Alaa’s sister Sanaa, who was previously jailed by the regime on bogus charges, visited Alaa on March 8.

If you’re based in the UK, we encourage you to write to your MP to urgently advocate for Alaa’s release (external link): https://freealaa.net/message-mp 

Supporters everywhere can share Alaa’s plight and Laila’s story on social media using the hashtags #FreeAlaa and #SaveLaila. Additionally, the campaign’s website (external link) offers additional actions, including purchasing Alaa’s book, and participating in a one-day solidarity hunger strike. You can also sign up for campaign updates by e-mail.

Every second counts, and time is running out. Keir Starmer and the British government must do everything it can to ensure Alaa’s immediate and unconditional release.

Tuberculosis lives and thrives in the lungs. When the bacteria that cause the disease are coughed into the air, they are thrust into a comparatively hostile environment, with drastic changes to their surrounding pH and chemistry. How these bacteria survive their airborne journey is key to their persistence, but very little is known about how they protect themselves as they waft from one host to the next.

Now MIT researchers and their collaborators have discovered a family of genes that becomes essential for survival specifically when the pathogen is exposed to the air, likely protecting the bacterium during its flight.

Many of these genes were previously considered to be nonessential, as they didn’t seem to have any effect on the bacteria’s role in causing disease when injected into a host. The new work suggests that these genes are indeed essential, though for transmission rather than proliferation.

“There is a blind spot that we have toward airborne transmission, in terms of how a pathogen can survive these sudden changes as it circulates in the air,” says Lydia Bourouiba, who is the head of the Fluid Dynamics of Disease Transmission Laboratory, an associate professor of civil and environmental engineering and mechanical engineering, and a core faculty member in the Instiute for Medical Engineering and Science at MIT. “Now we have a sense, through these genes, of what tools tuberculosis uses to protect itself.”

The team’s results, appearing this week in the Proceedings of the National Academy of Sciences, could provide new targets for tuberculosis therapies that simultaneously treat infection and prevent transmission.

“If a drug were to target the product of these same genes, it could effectively treat an individual, and even before that person is cured, it could keep the infection from spreading to others,” says Carl Nathan, chair of the Department of Microbiology and Immunology and R.A. Rees Pritchett Professor of Microbiology at Weill Cornell Medicine.

Nathan and Bourouiba are co-senior authors of the study, which includes MIT co-authors and mentees of Bourouiba in the Fluids and Health Network: co-lead author postdoc Xiaoyi Hu, postdoc Eric Shen, and student mentees Robin Jahn and Luc Geurts. The study also includes collaborators from Weill Cornell Medicine, the University of California at San Diego, Rockefeller University, Hackensack Meridian Health, and the University of Washington.

Pathogen’s perspective

Tuberculosis is a respiratory disease caused by Mycobacterium tuberculosis, a bacterium that most commonly affects the lungs and is transmitted through droplets that an infected individual expels into the air, often through coughing or sneezing. Tuberculosis is the single leading cause of death from infection, except during the major global pandemics caused by viruses.

“In the last 100 years, we have had the 1918 influenza, the 1981 HIV AIDS epidemic, and the 2019 SARS Cov2 pandemic,” Nathan notes. “Each of those viruses has killed an enormous number of people. And as they have settled down, we are left with a ‘permanent pandemic’ of tuberculosis.”

Much of the research on tuberculosis centers on its pathophysiology — the mechanisms by which the bacteria take over and infect a host — as well as ways to diagnose and treat the disease. For their new study, Nathan and Bourouiba focused on transmission of tuberculosis, from the perspective of the bacterium itself, to investigate what defenses it might rely on to help it survive its airborne transmission.

“This is one of the first attempts to look at tuberculosis from the airborne perspective, in terms of what is happening to the organism, at the level of being protected from these sudden changes and very harsh biophysical conditions,” Bourouiba says.

Critical defense

At MIT, Bourouiba studies the physics of fluids and the ways in which droplet dynamics can spread particles and pathogens. She teamed up with Nathan, who studies tuberculosis, and the genes that the bacteria rely on throughout their life cycle.

To get a handle on how tuberculosis can survive in the air, the team aimed to mimic the conditions that the bacterium experiences during transmission. The researchers first looked to develop a fluid that is similar in viscosity and droplet sizes to what a patient would cough or sneeze out into the air. Bourouiba notes that much of the experimental work that has been done on tuberculosis in the past has been based on a liquid solution that scientists use to grow the bacteria. But the team found that this liquid has a chemical composition that is very different from the fluid that tuberculosis patients actually cough and sneeze into the air.

Additionally, Bourouiba notes that fluid commonly sampled from tuberculosis patients is based on sputum that a patient spits out, for instance for a diagnostic test. “The fluid is thick and gooey and it’s what most of the tuberculosis world considers to represent what is happening in the body,” she says. “But it’s extraordinarily inefficient in spreading to others because it’s too sticky to break into inhalable droplets.”

Through Bourouiba’s work with fluid and droplet physics, the team determined the more realistic viscosity and likely size distribution of tuberculosis-carrying microdroplets that would be transmitted through the air. The team also characterized the droplet compositions, based on analyses of patient samples of infected lung tissues. They then created a more realistic fluid, with a composition, viscosity, surface tension and droplet size that is similar to what would be released into the air from exhalations.

Then, the researchers deposited different fluid mixtures onto plates in tiny individual droplets and measured in detail how they evaporate and what internal structure they leave behind. They observed that the new fluid tended to shield the bacteria at the center of the droplet as the droplet evaporated, compared to conventional fluids where bacteria tended to be more exposed to the air. The more realistic fluid was also capable of retaining more water.

Additionally, the team infused each droplet with bacteria containing genes with various knockdowns, to see whether the absence of certain genes would affect the bacteria’s survival as the droplets evaporated.

In this way, the team assessed the activity of over 4,000 tuberculosis genes and discovered a family of several hundred genes that seemed to become important specifically as the bacteria adapted to airborne conditions. Many of these genes are involved in repairing damage to oxidized proteins, such as proteins that have been exposed to air. Other activated genes have to do with destroying damaged proteins that are beyond repair.

“What we turned up was a candidate list that’s very long,” Nathan says. “There are hundreds of genes, some more prominently implicated than others, that may be critically involved in helping tuberculosis survive its transmission phase.”

The team acknowledges the experiments are not a complete analog of the bacteria’s biophysical transmission. In reality, tuberculosis is carried in droplets that fly through the air, evaporating as they go. In order to carry out their genetic analyses, the team had to work with droplets sitting on a plate. Under these constraints, they mimicked the droplet transmission as best they could, by setting the plates in an extremely dry chamber to accelerate the droplets’ evaporation, analogous to what they would experience in flight.

Going forward, the researchers have started experimenting with platforms that allow them to study the droplets in flight, in a range of conditions. They plan to focus on the new family of genes in even more realistic experiments, to confirm whether the genes do indeed shield Mycobacterium tuberculosis as it is transmitted through the air, potentially opening the way to weakening its airborne defenses.

“The idea of waiting to find someone with tuberculosis, then treating and curing them, is a totally inefficient way to stop the pandemic,” Nathan says. “Most people who exhale tuberculosis do not yet have a diagnosis. So we have to interrupt its transmission. And how do you do that, if you don’t know anything about the process itself? We have some ideas now.”

I’m old enough to remember when age verification bills were pitched as a way to ‘save the kids from porn’ and shield them from other vague dangers lurking in the digital world (like…“the transgender”). We have long cautioned about the dangers of these laws, and pointed out why they are likely to fail. While they may be well-intentioned, the growing proliferation of age verification schemes poses serious risks to all of our digital freedoms.

Fast forward a few years, and these laws have morphed into something else entirely—unfortunately, something we expected. What started as a misguided attempt to protect minors from "explicit" content online has spiraled into a tangled mess of privacy-invasive surveillance schemes affecting skincare products, dating apps, and even diet pills, threatening everyone’s right to privacy.

Age Verification Laws: A Backdoor to Surveillance

Age verification laws do far more than ‘protect children online’—they require the  creation of a system that collects vast amounts of personal information from everyone. Instead of making the internet safer for children, these laws force all users—regardless of age—to verify their identity just to access basic content or products. This isn't a mistake; it's a deliberate strategy. As one sponsor of age verification bills in Alabama admitted, "I knew the tough nut to crack that social media would be, so I said, ‘Take first one bite at it through pornography, and the next session, once that got passed, then go and work on the social media issue.’” In other words, they recognized that targeting porn would be an easier way to introduce these age verification systems, knowing it would be more emotionally charged and easier to pass. This is just the beginning of a broader surveillance system disguised as a safety measure.

This alarming trend is already clear, with the growing creep of age verification bills filed in the first month of the 2025-2026 state legislative session. Consider these three bills: 

1. Skincare: AB-728 in California
   Age verification just hit the skincare aisle! California’s AB-728 mandates age verification for anyone purchasing skin care products or cosmetics that contain certain chemicals like Vitamin A or alpha hydroxy acids. On the surface, this may seem harmless—who doesn't want to ensure that minors are safe from harmful chemicals? But the real issue lies in the invasive surveillance it mandates. A person simply trying to buy face cream could be forced to submit sensitive personal data through “an age verification system,” creating a system of constant tracking and data collection for a product that should be innocuous.
2. Dating Apps: A3323 in New York
   Match made in heaven? Not without your government-issued ID. New York’s A3323 bill mandates that online dating services verify users’ age, identity, and location before allowing access to their platforms. The bill's sweeping requirements introduce serious privacy concerns for all users. By forcing users to provide sensitive personal information—such as government-issued IDs and location data—the bill creates significant risks that this data could be misused, sold, or exposed through data breaches. 
3. Dieting products: SB 5622 in Washington State
   Shed your privacy before you shed those pounds! Washington State’s SB 5622 takes aim at diet pills and dietary supplements by restricting their sale to anyone under 18. While the bill’s intention is to protect young people from potentially harmful dieting products, it misses the mark by overlooking the massive privacy risks associated with the age verification process for everyone else. To enforce this restriction, the bill requires intrusive personal data collection for purchasing diet pills in person or online, opening the door for sensitive information to be exploited.

The Problem with Age Verification: No Solution Is Safe

Let’s be clear: no method of age verification is both privacy-protective and entirely accurate. The methods also don’t fall on a neat spectrum of “more safe” to “less safe.” Instead, every form of age verification is better described as “dangerous in one way” or “dangerous in a different way.” These systems are inherently flawed, and none come without trade-offs. Additionally, they continue to burden adults who just want to browse the internet or buy everyday items without being subjected to mass data collection.

For example, when an age verification system requires users to submit government-issued identification or a scan of their face, it collects a staggering amount of sensitive, often immutable, biometric or other personal data—jeopardizing internet users’ privacy and security. Systems that rely on credit card information, phone numbers, or other third-party material  similarly amass troves of personal data. This data is just as susceptible to being misused as any other data, creating vulnerabilities for identity theft and data breaches. These issues are not just theoretical: age verification companies can be—and already have been—hacked. These are real, ongoing concerns for anyone who values their privacy. 

We must push back against age verification bills that create surveillance systems and undermine our civil liberties, and we must be clear-eyed about the dangers posed by these expanding age verification laws. While the intent to protect children makes sense, the unintended consequence is a massive erosion of privacy, security, and free expression online for everyone. Rather than focusing on restrictive age verification systems, lawmakers should explore better, less invasive ways to protect everyone online—methods that don’t place the entire burden of risk on individuals or threaten their fundamental rights. 

EFF will continue to advocate for digital privacy, security, and free expression. We urge legislators to prioritize solutions that uphold these essential values, ensuring that the internet remains a space for learning, connecting, and creating—without the constant threat of surveillance or censorship. Whether you’re buying a face cream, swiping on a dating app, or browsing for a bottle of diet pills, age verification laws undermine that vision, and we must do better.
