Flashy exotic birds can actually glow in the dark

Biology, bioluminescence, birds, feathers, Fluorescence, Science / Mike M. / February 24, 2025

Found in the forests of Papua New Guinea, Indonesia, and Eastern Australia, birds of paradise are famous for flashy feathers and unusually shaped ornaments, which set the standard for haute couture among birds. Many use these feathers for flamboyant mating displays in which they shape-shift into otherworldly forms.

As if this didn’t attract enough attention, we’ve now learned that they also glow in the dark.

Biofluorescent organisms are everywhere, from mushrooms to fish to reptiles and amphibians, but few birds have been identified as having glowing feathers. This is why biologist Rene Martin of the University of Nebraska-Lincoln wanted to investigate. She and her team studied a treasure trove of specimens at the American Museum of Natural History, which have been collected since the 1800s, and found that 37 of the 45 known species of birds of paradise have feathers that fluoresce.

The glow factor of birds of paradise is apparently important for mating displays. Despite biofluorescence being especially prominent in males, attracting a mate might not be all it is useful for, as these birds might also use it to signal to each other in other ways and sometimes even for camouflage among the light and shadows.

“The current very limited number of studies reporting fluorescence in birds suggests this phenomenon has not been thoroughly investigated,” the researchers said in a study that was recently published in Royal Society Open Science.

How do they get that glow? Biofluorescence is a phenomenon that happens when shorter, high-energy wavelengths of light, meaning UV, violet, and blue, are absorbed by an organism. The energy then gets re-emitted at longer, lower-energy wavelengths—greens, yellows, oranges, and reds. The feathers of birds of paradise contain fluorophores, molecules that undergo biofluorescence. Specialized filters in the light-sensitive cells of their eyes make their visual system more sensitive to biofluorescence.

RFK Jr. promptly cancels vaccine advisory meeting, pulls flu shot campaign

Indefinite changes

Stat asked the HHS specifically about the Wild to Mild campaign as well as promotional campaigns for other vaccines, but an HHS spokesperson puzzlingly responded with a statement saying: “No, the CDC was not told to take down the flu vaccination campaign webpage,” which wasn’t what the outlet had asked about.

The statement went on to say: “Unfortunately, officials inside the CDC who are averse to Secretary Kennedy and President Trump’s agenda seem to be intentionally falsifying and misrepresenting guidance they receive.” NPR received the same statement.

Meanwhile on Thursday, The Washington Post reported that the HHS told the CDC to indefinitely postpone a meeting of its vaccine advisory committee (the Advisory Committee on Immunization Practices, or ACIP), which Kennedy has criticized. ACIP, comprised of independent experts, meets regularly to review and discuss vaccine safety and efficacy data and vote on recommendations.

ACIP was previously scheduled to meet February 26 to 28 to discuss a large number of vaccines, including those against meningitis, influenza, RSV, chikungunya, HPV, mpox, pneumococcal infections, Lyme disease, COVID-19, and CMV. An HHS spokesperson told the Post that the meeting was “postponed to accommodate public comment in advance of the meeting,” but there is no rescheduled date.

Leading medical experts and organizations, such as the American Medical Association, quickly sent a joint letter urging Kennedy to preserve the meeting. “Each ACIP meeting holds tremendous weight and relevance,” the letter states. ‘Infectious diseases are constantly evolving opponents; vaccines are among the best tools for constantly adapting and responding to the latest public health threats. … Making America healthy requires healthy discussion and timely, evidence-based decisions. This meeting should be no different.”

But, also on Thursday, Politico reported that Kennedy is preparing to remove ACIP members. And, the AP noted earlier that during a speech to HHS employees on Tuesday, Kennedy vowed to investigate the CDC’s childhood vaccine schedule, despite assuring senators prior to his confirmation that he would not make changes to it.

“We are gravely disappointed that the protections provided by ADP will not be available to our customers in the UK given the continuing rise of data breaches and other threats to customer privacy,” Apple said. “Enhancing the security of cloud storage with end-to-end encryption is more urgent than ever before.”

For UK Apple users, some data can still be encrypted. iCloud Keychain and Health, iMessage, and FaceTime will remain end-to-end encrypted by default. But other iCloud services will not be encrypted, effective immediately, including iCloud Backup, iCloud Drive, Photos, Notes, Reminders, Safari Bookmarks, Siri Shortcuts, Voice memos, Wallet passes, and Freeform.

In the future, Apple hopes to restore data protections in the UK, but the company refuses to ever build a backdoor for government officials.

“Apple remains committed to offering our users the highest level of security for their personal data and are hopeful that we will be able to do so in the future in the United Kingdom,” Apple said. “As we have said many times before, we have never built a backdoor or master key to any of our products or services, and we never will.”

Nissan’s latest desperate gamble—see if Tesla will buy the company

Cars, Nissan, Tesla / Mike M. / February 22, 2025

Senior politicians in Japan are not going to let Nissan die easily. The automaker has been struggling for some time now, with an outdated product portfolio, ongoing quarterly losses, and soon, the closure of factories and thousands of layoffs. The Japanese government has been trying to find a suitor and had hoped that Honda would do its patriotic duty and save its rival from extinction.

That deal—one branded “a desperate move” by former Nissan CEO and fugitive from Japanese justice Carlos Ghosn—fell apart last week after Renault demanded a price premium for its shares in Nissan, and Nissan demanded a merger of equals with Honda. In reality, it was always going to be a takeover, with very little in it for Honda in the way of complimentary product lines or access to new technologies.

Today, we learned of yet another desperate move—the former Japanese Prime Minister Yoshihide Suga is among a group that is trying to get Tesla to invest in Nissan instead.

Such a merger seems exceedingly far from likely, even if Tesla CEO Elon Musk wasn’t completely distracted dismantling the federal government and its workforce. While the company still maintains a ludicrous market capitalization thanks to retail investors who believe it is poised to sell billions of humanoid robots to every human on earth, as an automaker, it may well be struggling almost as much as Nissan.

As experts told us last year, Tesla is not a well-run enterprise. Its product range suffers, like Nissan’s, from being outdated compared to the competition. It appears that consumers have turned against the brand in Europe and increasingly the US, and its quarterly financial results have been more than disappointing of late. Tesla’s free cash flow fell by 18 percent in 2024 to $3.6 billion, although such is the value of Tesla stock that, were a Tesla-Nissan deal to happen, the former could pay for the latter with equity, should it entertain the idea seriously.

Leaked chat logs expose inner workings of secretive ransomware group

Biz & IT, black basta, chats, leaks, ransomware, Security / Mike M. / February 21, 2025

Researchers who have read the Russian-language texts said they exposed internal rifts in the secretive organization that have escalated since one of its leaders was arrested because it increases the threat of other members being tracked down as well. The heightened tensions have contributed to growing rifts between the current leader, believed to be Oleg Nefedov, and his subordinates. One of the disagreements involved his decision to target a bank in Russia, which put Black Basta in the crosshairs of law enforcement in that country.

“It turns out that the personal financial interests of Oleg, the group’s boss, dictate the operations, disregarding the team’s interests,” a researcher at Prodraft wrote. “Under his administration, there was also a brute force attack on the infrastructure of some Russian banks. It seems that no measures have been taken by law enforcement, which could present a serious problem and provoke reactions from these authorities.”

The leaked trove also includes details about other members, including two administrators using the names Lapa and YY, and Cortes, a threat actor linked to the Qakbot ransomware group. Also exposed are more than 350 unique links taken from ZoomInfo, a cloud service that provides data about companies and business individuals. The leaked links provide insights into how Black Basta members used the service to research the companies they targeted.

Security firm Hudson Rock said it has already fed the chat transcripts into ChatGPT to create BlackBastaGPT, a resource to help researchers analyze Black Basta operations.

Researchers figure out how to get fresh lithium into batteries

batteries, chemistry, materials science, Science / Mike M. / February 21, 2025

In their testing, they use a couple of unusual electrode materials, such as a chromium oxide (Cr₈O₂₁) and an organic polymer (a sulfurized polyacrylonitrile). Both of these have significant weight advantages over the typical materials used in today’s batteries, although the resulting batteries typically lasted less than 500 cycles before dropping to 80 percent of their original capacity.

But the striking experiment came when they used LiSO₂CF₃ to rejuvenate a battery that had been manufactured as normal but had lost capacity due to heavy use. Treating a lithium-iron phosphate battery that had lost 15 percent of its original capacity restored almost all of what was lost, allowing it to hold over 99 percent of its original charge. They also ran a battery for repeated cycles with rejuvenation every few thousand cycles. At just short of 12,000 cycles, it still could be restored to 96 percent of its original capacity.

Before you get too excited, there are a couple of things worth noting about lithium-iron phosphate cells. The first is that, relative to their charge capacity, they’re a bit heavy, so they tend to be used in large, stationary batteries like the ones in grid-scale storage. They’re also long-lived on their own; with careful management, they can take over 8,000 cycles before they drop to 80 percent of their initial capacity. It’s not clear whether similar rejuvenation is possible in the battery chemistries typically used for the sorts of devices that most of us own.

The final caution is that the battery needs to be modified so that fresh electrolytes can be pumped in and the gases released by the breakdown of the LiSO₂CF₃ removed. It’s safest if this sort of access is built into the battery from the start, rather than provided by modifying it much later, as was done here. And the piping needed would put a small dent in the battery’s capacity per volume if so.

All that said, the treatment demonstrated here would replenish even a well-managed battery closer to its original capacity. And it would largely restore the capacity of something that hadn’t been carefully managed. And that would allow us to get far more out of the initial expense of battery manufacturing. Meaning it might make sense for batteries destined for a large storage facility, where lots of them could potentially be treated at the same time.

Elon Musk to “fix” Community Notes after they contradict Trump

community notes, disinformation, Donald Trump, elon musk, fact checking, misinformation, Policy, Twitter, X / Mike M. / February 21, 2025

Elon Musk apparently no longer believes that crowdsourcing fact-checking through Community Notes can never be manipulated and is, thus, the best way to correct bad posts on his social media platform X.

Community Notes are supposed to be added to posts to limit misinformation spread after a broad consensus is reached among X users with diverse viewpoints on what corrections are needed. But Musk now claims a “fix” is needed to prevent supposedly outside influencers from allegedly gaming the system.

“Unfortunately, @CommunityNotes is increasingly being gamed by governments & legacy media,” Musk wrote on X. “Working to fix this.”

Musk’s announcement came after Community Notes were added to X posts discussing a poll generating favorable ratings for Ukraine President Volodymyr Zelenskyy. That poll was conducted by a private Ukrainian company in partnership with a state university whose supervisory board was appointed by the Ukrainian government, creating what Musk seems to view as a conflict of interest.

Although other independent polling recently documented a similar increase in Zelenskyy’s approval rating, NBC News reported, the specific poll cited in X notes contradicted Donald Trump’s claim that Zelenskyy is unpopular, and Musk seemed to expect X notes should instead be providing context to defend Trump’s viewpoint. Musk even suggested that by pointing to the supposedly government-linked poll in Community Notes, X users were spreading misinformation.

“It should be utterly obvious that a Zelensky[y]-controlled poll about his OWN approval is not credible!!” Musk wrote on X.

Musk’s attack on Community Notes is somewhat surprising. Although he has always maintained that Community Notes aren’t “perfect,” he has defended Community Notes through multiple European Union probes challenging their effectiveness and declared that the goal of the crowdsourcing effort was to make X “by far the best source of truth on Earth.” At CES 2025, X CEO Linda Yaccarino bragged that Community Notes are “good for the world.”

Yaccarino invited audience members to “think about it as this global collective consciousness keeping each other accountable at global scale in real time,” but just one month later, Musk is suddenly casting doubts on that characterization while the European Union continues to probe X.

Perhaps most significantly, Musk previously insisted as recently as last year that Community Notes could not be manipulated, even by Musk. He strongly disputed a 2024 report from the Center for Countering Digital Hate that claimed that toxic X users were downranking accurate notes that they personally disagreed with, claiming any attempt at gaming Community Notes would stick out like a “neon sore thumb.”

Microsoft’s new AI agent can control software and robots

The Magma model introduces two technical components: Set-of-Mark, which identifies objects that can be manipulated in an environment by assigning numeric labels to interactive elements, such as clickable buttons in a UI or graspable objects in a robotic workspace, and Trace-of-Mark, which learns movement patterns from video data. Microsoft says those features allow the model to complete tasks like navigating user interfaces or directing robotic arms to grasp objects.

Microsoft Magma researcher Jianwei Yang wrote in a Hacker News comment that the name “Magma” stands for “M(ultimodal) Ag(entic) M(odel) at Microsoft (Rese)A(rch),” after some people noted that “Magma” already belongs to an existing matrix algebra library, which could create some confusion in technical discussions.

Reported improvements over previous models

In its Magma write-up, Microsoft claims Magma-8B performs competitively across benchmarks, showing strong results in UI navigation and robot manipulation tasks.

For example, it scored 80.0 on the VQAv2 visual question-answering benchmark—higher than GPT-4V’s 77.2 but lower than LLaVA-Next’s 81.8. Its POPE score of 87.4 leads all models in the comparison. In robot manipulation, Magma reportedly outperforms OpenVLA, an open source vision-language-action model, in multiple robot manipulation tasks.

As always, we take AI benchmarks with a grain of salt since many have not been scientifically validated as being able to measure useful properties of AI models. External verification of Microsoft’s benchmark results will become possible once other researchers can access the public code release.

Like all AI models, Magma is not perfect. It still faces technical limitations in complex step-by-step decision-making that requires multiple steps over time, according to Microsoft’s documentation. The company says it continues to work on improving these capabilities through ongoing research.

Yang says Microsoft will release Magma’s training and inference code on GitHub next week, allowing external researchers to build on the work. If Magma delivers on its promise, it could push Microsoft’s AI assistants beyond limited text interactions, enabling them to operate software autonomously and execute real-world tasks through robotics.

Magma is also a sign of how quickly the culture around AI can change. Just a few years ago, this kind of agentic talk scared many people who feared it might lead to AI taking over the world. While some people still fear that outcome, in 2025, AI agents are a common topic of mainstream AI research that regularly takes place without triggering calls to pause all of AI development.

See a garbage truck’s CNG cylinders explode after lithium-ion battery fire

Cars, CNG, fire, garbage truck fire, Lithium batteries / Mike M. / February 20, 2025

When firefighters arrived on scene, they asked the driver to dump his load in the street, which would reduce the risk of anything on the truck itself—gasoline, CNG, etc.—catching fire. Then the firefighters could put out the blaze easily, treating it like a normal trash fire, and have Groot haul away the debris afterward. But this didn’t work either. The flames had spread far enough by this point to put the truck’s dumping mechanism out of commission.

So, firefighters unrolled hoses and hooked up to a nearby fire hydrant. They recognized that the truck was CNG-powered, as were many Groot vehicles. CNG offers a lower maintenance cost, uses less fuel, and creates less pollution than diesel, but best practices currently suggest not spraying CNG cylinders directly with water. Firefighters instead tried to aim water right into the back of the garbage truck without wetting the CNG cylinders nearby on the roof.

They were waiting for the telltale hiss of the pressure relief system to trigger. These valves typically open within two to five minutes, depending on fire conditions, and they should be capable of venting all their natural gas some minutes before the CNG canisters would otherwise be in danger of exploding. But the hiss never came, and as Fire Chief Lance Harris and his crew worked to secure the scene and put water onto the burning load, the CNG canisters exploded catastrophically instead.

In a board of trustees meeting this week in Arlington Heights, Harris recounted the incident, noting that he felt lucky to be alive—and thankful that no township personnel or residents sustained serious injuries.

“We can’t prove it,” he said, but after two months of investigating the situation, his department had concluded with high probability that the fire had been caused by a lithium-ion battery discarded into a recycling container. This suspicion was based on the amount of fire and the heat and speed with which it burned; lithium-ion batteries that enter “thermal runaway” can burn hot, at around 750° Fahrenheit (399° C).

Harris’ takeaway was clear: recycle even small lithium-ion batteries responsibly, as they can cause real hazards if placed into the waste system, where they are often impacted or compressed.

FTC investigates “tech censorship,” says it’s un-American and may be illegal

ftc, Policy / Mike M. / February 20, 2025

The Federal Trade Commission today announced a public inquiry into alleged censorship online, saying it wants “to better understand how technology platforms deny or degrade users’ access to services based on the content of their speech or affiliations, and how this conduct may have violated the law.”

“Tech firms should not be bullying their users,” said FTC Chairman Andrew Ferguson, who was chosen by President Trump to lead the commission. “This inquiry will help the FTC better understand how these firms may have violated the law by silencing and intimidating Americans for speaking their minds.”

The FTC announcement said that “censorship by technology platforms is not just un-American, it is potentially illegal.” Tech platforms’ actions “may harm consumers, affect competition, may have resulted from a lack of competition, or may have been the product of anti-competitive conduct,” the FTC said.

The Chamber of Progress, a lobby group representing tech firms, issued a press release titled, “FTC Chair Rides MAGA ‘Tech Censorship’ Hobby Horse.”

“Republicans have spent nearly a decade campaigning against perceived social media ‘censorship’ by attempting to dismantle platforms’ ability to moderate content, despite well-established Supreme Court precedent,” the group said. “Accusations of ‘tech censorship’ also ignore the fact that conservative publishers and commentators receive broader engagement than liberal voices.”

Last year, the Supreme Court found that a Texas state law prohibiting large social media companies from moderating posts based on a user’s “viewpoint” is unlikely to withstand First Amendment scrutiny. The Supreme Court majority opinion said the court “has many times held, in many contexts, that it is no job for government to decide what counts as the right balance of private expression—to ‘un-bias’ what it thinks biased, rather than to leave such judgments to speakers and their audiences. That principle works for social-media platforms as it does for others.”

Scientists unlock vital clue to strange quirk of static electricity

electromagnetism, Physics, Science, static electricity, triboelectric effect / Mike M. / February 19, 2025

Scientists can now explain the prevailing unpredictability of contact electrification, unveiling order from what has long been considered chaos.

Static electricity—specifically the triboelectric effect, aka contact electrification—is ubiquitous in our daily lives, found in such things as a balloon rubbed against one’s hair or styrofoam packing peanuts sticking to a cat’s fur (as well as human skin, glass tabletops, and just about anywhere you don’t want packing peanuts to be). The most basic physics is well understood, but long-standing mysteries remain, most notably how different materials exchange positive and negative charges—sometimes ordering themselves into a predictable series, but sometimes appearing completely random.

Now scientists at the Institute of Science and Technology Austria (ISTA) have identified a critical factor explaining that inherent unpredictability: It’s the contact history of given materials that controls how they exchange charges in contact electrification. They described their findings in a new paper published in the journal Nature.

Johan Carl Wilcke published the first so-called “triboelectric series” in 1757 to describe the tendency of different materials to self-order based on how they develop a positive or negative charge. A material toward the bottom of the list, like hair, will acquire a more negative charge when it comes into contact with a material near the top of the list, like a rubber balloon.

The issue with all these lists is that they are inconsistent and unpredictable—sometimes the same scientists don’t get the same ordering results twice when repeating experiments—largely because there are so many confounding factors that can come into play. “Understanding how insulating materials exchanged charge seemed like a total mess for a very long time,” said co-author Scott Waitukaitis of ISTA. “The experiments are wildly unpredictable and can sometimes seem completely random.”

A cellulose material’s charge sign, for instance, can depend on whether its curvature is concave or convex. Two materials can exchange charge from positive (A) to negative (B), but that exchange can reverse over time, with B being positive and A being negative. And then there are “triangles”: Sometimes one material (A) gains a positive charge when rubbed up against another material (B), but B will gain a positive charge when rubbed against a third material (C), and C, in turn, will gain positive charge when in contact with A. Even identical materials can sometimes exchange charge upon contact.

By the end of today, NASA’s workforce will be about 10 percent smaller

cuts, NASA, Space, workforce / Mike M. / February 18, 2025

Spread across NASA’s headquarters and 10 field centers, which dot the United States from sea to sea, the space agency has had a workforce of nearly 18,000 civil servants.

However, by the end of today, that number will have shrunk by about 10 percent since the beginning of the second Trump administration four weeks ago. And the world’s preeminent space agency may still face significant additional cuts.

According to sources, about 750 employees at NASA accepted the “fork in the road” offer to take deferred resignation from the space agency later this year. This sounds like a lot of people, but generally about 1,000 people leave the agency every year, so effectively, many of these people might just be getting paid to leave jobs they were already planning to exit from.

The culling of “probationary” employees will be more impactful. As it has done at other federal agencies, the Trump administration is generally firing federal employees who are in the “probationary” period of their employment, which includes new hires within the last one or two years or long-time employees who have moved into or been promoted into a new position. About 1,000 or slightly more employees at NASA were impacted by these cuts.

Adding up the deferred resignations and probationary cuts, the Trump White House has now trimmed about 10 percent of the agency’s workforce.

However, the cuts may not stop there. Two sources told Ars that directors at the agency’s field centers have been told to prepare options for a “significant” reduction in force in the coming months. The scope of these cuts has not been defined, and it’s possible they may not even happen, given that the White House must negotiate budgets for NASA and other agencies with the US Congress. But this directive for further reductions in force casts more uncertainty on an already demoralized workforce and signals that the Trump administration would like to make further cuts.
