NPR reports on "a monster black hole that's been lurking unseen in the galaxy next door." This appears to be the closest supermassive black hole outside our Milky Way galaxy, according to a report that's appearing in The Astrophysical Journal... "Now that there is strong evidence that it should be there, you can rest assured that we are very excitedly following up," says Jesse Han of the Center for Astrophysics, Harvard & Smithsonian, who led the study... Han and his colleagues realized that this black hole must exist when they were studying so-called hypervelocity stars... [T]hey started out as normal stars that were part of a binary system, or two stars orbiting each other. When that kind of pair ventures too close to a supermassive black hole, says Han, "what can happen is one of the stars can get captured by the black hole. It is basically ripped apart from its companion." The bereft companion star, meanwhile, gets flung away, going at ridiculously high speeds. It's as if the black hole basically hurled it out of the galaxy. And that explains some of what's happening in our own galaxy, writes Space.com: Tracing the trajectory of these super-speed stars using the European Space Agency's star-tracking Gaia satellite, the researchers discovered that around half of them were accelerated by the Milky Way's own supermassive black hole, Sagittarius A*. The other half, the team believes, likely fled to the outskirts of the Milky Way after a gravitational encounter with a supermassive black hole at the heart of the LMC separated these stars from their stellar binary partners. "It is astounding to realize that we have another supermassive black hole just down the block, cosmically speaking," team leader Jesse Han of the Center for Astrophysics | Harvard & Smithsonian (CfA) said in a statement. "Black holes are so stealthy that this one has been practically under our noses this whole time." "Their calculations suggest that the Large Magellanic Cloud must be harboring a black hole that's about 600,000 times the mass of our Sun," adds NPR. "That's smaller than the black hole at the center of the Milky Way, which is about 4 million times more massive than the Sun." Astronomers had previously thought the Large Magellanic Cloud should have a big black hole, but until now there's been no evidence of it, says Han... Now, though, astronomers have a better sense of where to hunt for any X-ray, radio, or visible-light signatures that are the telltale signs of an invisible black hole that's devouring everything nearby. "It is within the realm of possibilities that it is already detectable in radio and X-ray and optical," says Han. "We just haven't looked at the right place."

gdm (Slashdot reader #97,336) writes: A study published in Transportation Research Interdisciplinary Perspectives investigates how ants avoid traffic jams.... Quoting the abstract: "The results show that ants adopt specific traffic strategies (platoon formation, quasi-constant speed and no overtaking maneuvers) that help avoid jam phenomena, even at high density." "Researchers are now studying these insects' cooperative tactics to learn how to program self-driving cars that don't jam up," writes Scientific American: "We're maximizing the interests of individuals, [which] is why, at a given point, you start to have a traffic jam," says study co-author Nicola Pugno, who studies sustainable engineering at the University of Trento in Italy. But self-driving cars, if they one day become ubiquitous, could have more cooperative programming. In one vision of this future, autonomous vehicles would share information with nearby cars to optimize traffic flow — perhaps, the researchers suggest, by prioritizing constant speeds and headways or by not passing others on the road... Today's drivers can learn at least one thing from ants to avoid causing a traffic jam, says Katsuhiro Nishinari [a mathematical physicist at the University of Tokyo, who studies traffic]: don't tailgate. By leaving room between their car and the one ahead of them, drivers can absorb a wave of braking in dense traffic conditions that would otherwise be amplified into a full-blown "phantom" traffic jam with no obvious cause. "Just keeping away," he says, can help traffic flow smoothly. In the article the researchers admit there are differences between humans stuck in traffic and ants. "Unlike cars, ants don't crash; they can literally walk over one another." And if they're backed up in a tunnel, "they'll find a way to walk on the ceiling!"

Philosophy/ethics professor Troy Jollimore looks at the implications of a world where many students are submitting AI-generated essays. ("Sometimes they will provide quotations, giving page numbers that, as often as not, do not seem to correspond to anything in the actual world...") Ideally if the students write the essays themselves, "some of them start to feel it. They begin to grasp that thinking well, and in an informed manner, really is different from thinking poorly and from a position of ignorance. That moment, when you start to understand the power of clear thinking, is crucial. "The trouble with generative AI is that it short-circuits that process entirely." One begins to suspect that a great many students wanted this all along: to make it through college unaltered, unscathed. To be precisely the same person at graduation, and after, as they were on the first day they arrived on campus. As if the whole experience had never really happened at all. I once believed my students and I were in this together, engaged in a shared intellectual pursuit. That faith has been obliterated over the past few semesters. It's not just the sheer volume of assignments that appear to be entirely generated by AI — papers that show no sign the student has listened to a lecture, done any of the assigned reading, or even briefly entertained a single concept from the course... It's other things too... The students who beg you to reconsider the zero you gave them in order not to lose their scholarship. (I want to say to them: Shouldn't that scholarship be going to ChatGPT?â) It's also, and especially, the students who look at you mystified. The use of AI already seems so natural to so many of them, so much an inevitability and an accepted feature of the educational landscape, that any prohibition strikes them as nonsensical. Don't we instructors understand that today's students will be able, will indeed be expected, to use AI when they enter the workforce? Writing is no longer something people will have to do in order to get a job. Or so, at any rate, a number of them have told me. Which is why, they argue, forcing them to write in college makes no sense. That mystified look does not vanish — indeed, it sometimes intensifies — when I respond by saying: Look, even if that were true, you have to understand that I don't equate education with job training. What do you mean? they might then ask. And I say: I'm not really concerned with your future job. I want to prepare you for life... My students have been shaped by a culture that has long doubted the value of being able to think and write for oneself — and that is increasingly convinced of the power of a machine to do both for us. As a result, when it comes to writing their own papers, they simply disregard it. They look at instructors who levy such prohibitions as irritating anachronisms, relics of a bygone, pre-ChatGPT age.... As I go on, I find that more of the time, energy, and resources I have for teaching are dedicated to dealing with this issue. I am doing less and less actual teaching, more and more policing. Sometimes I try to remember the last time I actually looked forward to walking into a classroom. It's been a while.

Slashdot covered the Bulwer-Lytton Fiction Contest in 2008 and 2010 — though it's been running since 1983. Entrants competed to write the worst-possible first sentence for a novel, in a contest started by English professor Scott E. Rice at San Jose State University (which sponsored the contest). In its first year it drew over 10,000 entries! Over the years the bad first sentences were even collected into actual books (that were edited by Rice). But after 43 years, Rice delivered his own disappointing first sentence. "It is with deep regrets that I announce the conclusion of the Bulwer-Lytton Fiction Contest." Being a year and a half older than Joseph Biden, I find the BLFC becoming increasingly burdensome and would like to put myself out to pasture while I still have some vim and vigor! When I initiated the competition in 1983, inviting entrants to submit bad opening sentences to imaginary novels, I never dreamed that we would receive thousands of entrants from all over the U.S. and the globe, or that the contest would survive for over four decades. I am especially grateful to our entrants for keeping the contest alive and to our Panel of Undistinguished Judges who dutifully selected each year's "winners." And, of course, I would like to thank my daughter, EJ, who has been indispensable the last several years of the contest. It's been 42 good years but, alas, all good things must come to an end. Rest assured we're keeping the BLFC spirit alive by maintaining our archive for posterity so that generations and generations hence may witness your greatness! His daughter EJ added their own words of thanks: Lastly, any little bit you could spare towards helping us keep the archive going (a few bucks is great!) would be greatly appreciated (EJ's Venmo is @elizabeth-rice-12). Thank you so much for your joy and enthusiasm — the noble Bulweriers have made working on the contest a treasure!!

Damaged corneas were repaired at a Harvard teaching hospital in a unique clinical trial, reports New Atlas: Since it's on the frontline of potential hazards from the outside world, the cornea features a population of limbal epithelial stem cells, which repair minor damage to keep the surface smooth and functional... The new study, conducted by scientists at Massachusetts Eye and Ear, investigated a new treatment called cultivated autologous limbal epithelial cells (CALEC). This involves removing stem cells from a patient's uninjured eye, growing their population in the lab for a few weeks, then surgically transplanting them into the injured eye. The phase 1/2 trial recruited 14 patients to undergo the procedure, and followed them for 18 months afterwards... By the first checkup at three months, the corneas of seven (50%) of the participants had been completely restored. By the 12-month mark, that number had increased to 11 (79%) patients. Two other participants met the definition for partial success, so the team claims an overall success rate of 92% for CALEC.

Slashdot reader databasecowgirl writes: The Times is reporting an interesting study published in Science in which mice demonstrated doing first aid. In the replicated study, an anaesthetised mouse is exposed to another mouse who recognises the distress and clears airway to revive the unconscious mouse. The mice had never seen an unconscious animal before, so the behaviour is thought to be instinctive. From the Times: Large social mammals have previously been documented lending assistance to each other. Chimpanzees have been seen tending to wounded companions, dolphins are known to push distressed pod members to the surface to help them breathe, and elephants have been observed assisting their ailing relatives. Never before, however, has such a meticulous, paws-on approach to first aid been recorded in a creature as small as a mouse.

"McDonald's is giving its 43,000 restaurants a technology makeover," reports the Wall Street Journal, including AI-enabled drive-throughs and AI-powered tools for managers — as well as internet-connected kitchen equipment. "Technology solutions will alleviate the stress...." says McDonald's CIO Brian Rice. McDonald's tapped Google Cloud in late 2023 to bring more computing power to each of its restaurants — giving them the ability to process and analyze data on-site... a faster, cheaper option than sending data to the cloud, especially in more far-flung locations with less reliable cloud connections, said Rice... Edge computing will enable applications like predicting when kitchen equipment — such as fryers and its notorious McFlurry ice cream machines — is likely to break down, Rice said. The burger chain said its suppliers have begun installing sensors on kitchen equipment that will feed data to the edge computing system and give franchisees a "real-time" view into how their restaurants are operating. AI can then analyze that data for early signs of a maintenance problem. McDonald's is also exploring the use of computer vision, the form of AI behind facial recognition, in store-mounted cameras to determine whether orders are accurate before they're handed to customers, he said. "If we can proactively address those issues before they occur, that's going to mean smoother operations in the future," Rice added... Additionally, the ability to tap edge computing will power voice AI at the drive-through, a capability McDonald's is also working with Google's cloud-computing arm to explore, Rice said. The company has been experimenting with voice-activated drive-throughs and robotic deep fryers since 2019, and ended its partnership with International Business Machines to test automated order-taking at the drive-through in 2024. Edge computing will also help McDonald's restaurant managers oversee their in-store operations. The burger giant is looking to create a "generative AI virtual manager," Rice said, which handles administrative tasks such as shift scheduling on managers' behalf. Fast-food giant Yum Brands' Pizza Hut and Taco Bell have explored similar capabilities.

A blog post from the Stanford University School of Medicine attempts to answer the question: What's the deal with the gut-brain connection? It affects your mood, your sleep, even your motivation to exercise. There's convincing evidence that it's the starting point for Parkinson's disease and could be responsible for long COVID's cognitive effects. And it sits about 2 feet below your brain. The gut plays an obvious role in our health by digesting what we eat and extracting nutrients. But there's a growing appreciation among scientists that our digestive systems affect our general well-being in a much broader fashion. One fascinating aspect of the gut's widespread impact on health is its direct influence on and communication with the brain, a conduit known as the gut-brain axis. Through direct signals from the vagus nerve, [which] connects the brain and the gut, as well as through molecules secreted into the bloodstream from our gut microbes and immune cells that traffic from the gut to the rest of the body, our brains and our digestive tracts are in constant communication. And when that communication goes off the rails, diseases and disorders can result. The gut-brain connection is a key part of how the brain forms a picture of the rest of the body, a phenomenon known as interoception, explained Christoph Thaiss, PhD, an assistant professor of pathology at Stanford Medicine... The gut also contains the largest number of neurons outside the brain of any structure in the body — more than 100 million neurons line the human digestive tract, from the esophagus to the anus. These cells make up what is known as the enteric nervous system, which some scientists refer to as a "second brain." The enteric nervous system is more brain-like than other peripheral nerves because it consists of lots of different types of neurons that communicate with each other, while other peripheral nerves primarily serve to communicate between the brain and the body, said Julia Kaltschmidt, PhD, the Firmenich Next Generation Faculty Scholar and an associate professor of neurosurgery. In fact, the gut's nervous system can act alone. Scientists have found that if they remove an animal's gut and bathe it in a special fluid designed to keep neurons alive, the gut continues to contract, pushing its contents from top to bottom.

Last week Google urged the U.S. government not to break up the company — but apparently, it didn't work. In a new filing Friday, America's Justice Department "reiterated its November proposal that Google be forced to sell its Chrome web browser," reports the Washington Post, "to address a federal judge finding the company guilty of being an illegal monopoly in August." The government also kept a proposal that Google be banned from paying other companies to give its search engine preferential placement on their apps and phones. At the same time, the government dropped its demand that Google sell its stakes in AI start-ups after one of the start-ups, Anthropic AI, argued that it needed Google's money to compete in the fast-growing industry. The government's final proposal "reaffirms that Google must divest the Chrome browser — an important search access point — to provide an opportunity for a new rival to operate a significant gateway to search the internet, free of Google's monopoly control," Justice Department lawyers wrote in the filing... Judge Amit Mehta, of the U.S. District Court for the District of Columbia, who had ruled that Google held an illegal monopoly, will decide on the final remedies in April. The article quotes a Google spokesperson's response: that the Justice Department's "sweeping" proposals "continue to go miles beyond the court's decision, and would harm America's consumers, economy and national security."

U.S. president Donald Trump called Daylight Saving Time "very costly to our nation" and "inconvenient" in December. Today the Washington Post remembers he'd vowed his Republican party would use their "best efforts" to eliminate it. But it's still proving to be politically difficult... Polls have shown that most Americans oppose the time shifts but disagree on what should replace them... [U.S. political leaders] also say they are grappling with whether the nation should permanently move the clocks forward one hour, an idea championed by lawmakers on the coasts who say it would allow for more sunshine during the winter, or remain on year-round standard time, which is favored by neurologists who say it aligns with our circadian rhythms. That decision would rest with Congress, not the president. The split often reflects regional, not political, differences, based on where time zones fall; a year-round "spring forward" would mean winter sunrises that could creep past 9 a.m. in cities such as Indianapolis and Detroit, prompting many local lawmakers to oppose the idea... [A 2022 Senate vote to make Daylight Saving Time permanent] awoke a new lobbying effort from advocates such as the American Academy of Sleep Medicine, which warned that year-round daylight saving time would be unhealthy, citing risks such as higher rates of obesity or metabolic dysfunction. Some researchers warned of a condition dubbed "social jetlag," saying that internal body clocks and rhythms would be persistently misaligned if human clocks were permanently set forward an hour. The concerted resistance from the health groups — which some congressional aides jokingly referred to as "Big Sleep" — helped kill the measure in the House and has contributed to a stalemate over how to proceed... Today, roughly two-thirds of Americans want to end the clock changes, polls show. But even those Americans don't agree on what should come next. An October 2023 YouGov poll found that 33 percent of respondents wanted year-round daylight saving time, 23 percent wanted permanent standard time, and 9 percent had no preference. The remainder weren't sure or preferred to remain on the current system... The political fight is far from over, with Trump allies such as Sen. Tommy Tuberville (R-Alabama) pledging to keep pushing for year-round daylight saving time. Some congressional Republicans also have privately called for a hearing in front of the House Energy and Commerce Committee, with hopes of advancing the Sunshine Protection Act.

As Christie's auction house planned the first-ever auction dedicated to AI-generated art works, over 5,600 people signed an online letter urging them to cancel it. "Many of the artworks you plan to auction were created using AI models that are known to be trained on copyrighted work without a license," the letter complained. "These models, and the companies behind them, exploit human artists, using their work without permission or payment to build commercial AI products that compete with them. Your support of these models, and the people who use them, rewards and further incentivizes AI companies' mass theft of human artists' work." CNET reports that the signers "range from illustrators to authors to art therapists to cinematographers, from countries all across the globe." Christie's ignored them all and held the auction anyways. So what happened when it was over on Wednesday morning? More than 30 lots attracted hundreds of bids and brought in $728,784, Christie's reports. And there's a generational twist: The auction house says 37% of registrants were completely new to Christie's, and 48% of bidders were millennials or members of Gen Z... The highest price in the sale was $277,200 for a work by Refik Anadol titled Machine Hallucinations — ISS Dreams — A. It used a data set of more than 1.2 million images taken from the International Space Station and satellites. ARTnews reports that the auction actually brought in more than Christie's had expected: The sale, which made up of 34 lots, had an 82 percent sell through rate... While some digital artists, including Beeple, championed the sale, others decried it as emblematic of the ongoing struggle between human artistry and machine-driven innovation. The results, however, suggest that AI art — controversial as it may be — is carving a firm place in the market.

"The early web was fun," Reddit co-founder Alexis Ohanian posted Wednesday on X.com. "It was weird. It was community-driven. It's time to rebuild that. "Which is why Kevin Rose and I just bought back Digg." The amount of that purchase is "undisclosed," reports CNBC: The deal is backed by venture capital firms True Ventures, where Rose is a partner, and Ohanian's Seven Seven Six.... The company said in a release that it aims to differentiate itself in the social media market by "focusing on AI innovations designed to enhance the user experience and build a human-centered alternative...." Rose said in a post on X that he and Ohanian "dreamed up features that weren't even possible with yesterday's tech." "We're bringing more transparency and community partnership," according to Rose's post, "unlike anything you've seen, plus AI that unlocks creativity without sanitizing the human element. The timing is finally right to reimagine what's possible." "I really disliked you for a long time," Ohanian tells Rose in their joint announcement video. (To which a cheery Rose responds, "Rightfully so.") But in the video Ohanian also says that today "Our perspective on the world has shifted a lot. You don't want to live in the past, but now we actually have the technology to make better, healthier community experiences."

This week the Free Software Foundation "backed a lone developer's brave effort to overturn a pivotal court ruling that threatens to undermine the AGPLv3 — the foundation's GNU Affero General Public License, version 3," reports the Register. "At stake is the future of not just the AGPLv3, but the FSF's widely used GNU Public License it is largely based on, and the software covered by those agreements." A core tenet of the GPL series is that free software remains free forever, and this is woven into the licenses' fine print. This ongoing legal battle is a matter of whether people can alter those licenses and redistribute code as they see fit in a non-free way, or if they must stick to the terms of an agreement that says the terms cannot be changed... If the Ninth Circuit upholds the [original district court] ruling, it's likely to create a binding precedent that would limit one of the major freedoms that AGPLv3 and other GPL licenses aim to protect — the ability to remove restrictions added to GPL licensed code. "Neo4j appended an additional nonfree commercial restriction, the Commons Clause, to a verbatim version of the GNU AGPLv3 in a version of its software..." according to an FSF announcement this week. "The FSF's position on such confusing licensing practices has always been clear: the GNU licenses explicitly allow users to remove restrictions incompatible with the four freedoms." (You can read their amicus brief here.) Thanks to Slashdot reader jms00 for sharing the news.

Axiom Space and Red Hat will collaborate to launch Data Center Unit-1 (AxDCU-1) to the International Space Station this spring. It's a small data processing prototype (powered by lightweight, edge-optimized Red Hat Device Edge) that will demonstrate initial Orbital Data Center (ODC) capabilities. "It all sounds rather grand for something that resembles a glorified shoebox," reports the Register. Axiom Space said: "The prototype will test applications in cloud computing, artificial intelligence, and machine learning (AI/ML), data fusion and space cybersecurity." Space is an ideal environment for edge devices. Connectivity to datacenters on Earth is severely constrained, so the more processing that can be done before data is transmitted to a terrestrial receiving station, the better. Tony James, chief architect, Science and Space at Red Hat, said: "Off-planet data processing is the next frontier, and edge computing is a crucial component. With Red Hat Device Edge and in collaboration with Axiom Space, Earth-based mission partners will have the capabilities necessary to make real-time decisions in space with greater reliability and consistency...." The Red Hat Device Edge software used by Axiom's device combines Red Hat Enterprise Linux, the Red Hat Ansible Platform, and MicroShift, a lightweight Kubernetes container orchestration service derived from Red Hat OpenShift. The plan is for Axiom Space to host hybrid cloud applications and cloud-native workloads on-orbit. Jason Aspiotis, global director of in-space data and security, Axiom Space, told The Register that the hardware itself is a commercial off-the-shelf unit designed for operation in harsh environments... "AxDCU-1 will have the ability to be controlled and utilized either via ground-to-space or space-to-space communications links. Our current plans are to maintain this device on the ISS. We plan to utilize this asset for at least two years." The article notes that HPE has also "sent up a succession of Spaceborne computers — commercial, off-the-shelf supercomputers — over the years to test storage, recovery, and operational potential on long-duration missions." (They apparently use Red Hat Enterprise Linux.) "At the other end of the scale, the European Space Agency has run Raspberry Pi computers on the ISS for years as part of the AstroPi educational outreach program." Axiom Space says their Orbital Data Center is deigned to "reduce delays traditionally associated with orbital data processing and analysis." By utilizing Earth-independent cloud storage and edge processing infrastructure, Axiom Space ODCs will enable data to be processed closer to its source, spacecraft or satellites, bypassing the need for terrestrial-based data centers. This architecture alleviates reliance on costly, slow, intermittent or contested network connections, creating more secure and quicker decision-making in space. The goal is to allow Axiom Space and its partners to have access to real-time processing capabilities, laying the foundation for increased reliability and improved space cybersecurity with extensive applications. Use cases for ODCs include but are not limited to supporting Earth observation satellites with in-space and lower latency data storage and processing, AI/ML training on-orbit, multi-factor authentication and cyber intrusion detection and response, supervised autonomy, in-situ space weather analytics and off-planet backup & disaster recovery for critical infrastructure on Earth.

"PepsiCo is launching a new product, Simply Ruffles Hot & Spicy, which uses natural ingredients like tomato powder and red chile pepper instead of artificial dyes," reports Bloomberg. But it's part of a larger trend: In one of the final acts of President Joe Biden's administration, the U.S. Food and Drug Administration banned Red No. 3, effective in January 2027 for food, one of a handful of synthetic colors that have become something of a symbol of all that is wrong with the American food system and the ultraprocessed foods that dominate it. Putting Red No. 3 aside, the rest of the colors remain legal, and they're used in tens of thousands of supermarket and convenience-store products in the United States, according to NielsenIQ data. The recent campaign against them became one of the pillars of the "Make America Healthy Again" movement championed by Health and Human Services Secretary Robert F. Kennedy Jr. The criticism follows what health advocates have been saying for years: The synthetic colors add nothing to taste, nutritional value or shelf life but make unhealthy foods more visually appealing. Worst of all, there are concerns that the dyes may be carcinogenic or trigger hyperactivity in some kids. [Ian Puddephat, vice president of research and development for food ingredients at PepsiCo] says PepsiCo is "on a mission to get them out of the portfolio as much as we can"... PepsiCo has a dozen brands, including Simply, that don't have the artificial dyes, and the company is working to pull them out of an additional eight brands in the next year. Other companies are trying too, according to the article. Though Ironically, "the supply chain for colors like a radish's red or annatto's orange is not as robust as that for Red No. 40 or Yellow No. 6." But there's also been some success stories: In 2016, Kraft Heinz Foods Co. announced that it'd made good on an earlier promise to get artificial dyes out of its recipe — and apparently, nobody noticed. "We just haven't told that story," says Carlos Abrams-Rivera, Kraft Heinz's CEO. (The lack of artificial dyes is more prominent on the boxes now...) Thanks to long-time Slashdot schwit1 for haring the article.

"The ubiquitous ESP32 microchip made by Chinese manufacturer Espressif and used by over 1 billion units as of 2023 contains an undocumented 'backdoor' that could be leveraged for attacks," writes BleepingComputer. "The undocumented commands allow spoofing of trusted devices, unauthorized data access, pivoting to other devices on the network, and potentially establishing long-term persistence." This was discovered by Spanish researchers Miguel Tarascó Acuña and Antonio Vázquez Blanco of Tarlogic Security, who presented their findings yesterday at RootedCON in Madrid. "Tarlogic Security has detected a backdoor in the ESP32, a microcontroller that enables WiFi and Bluetooth connection and is present in millions of mass-market IoT devices," reads a Tarlogic announcement shared with BleepingComputer. "Exploitation of this backdoor would allow hostile actors to conduct impersonation attacks and permanently infect sensitive devices such as mobile phones, computers, smart locks or medical equipment by bypassing code audit controls...." Tarlogic developed a new C-based USB Bluetooth driver that is hardware-independent and cross-platform, allowing direct access to the hardware without relying on OS-specific APIs. Armed with this new tool, which enables raw access to Bluetooth traffic, Targolic discovered hidden vendor-specific commands (Opcode 0x3F) in the ESP32 Bluetooth firmware that allow low-level control over Bluetooth functions. In total, they found 29 undocumented commands, collectively characterized as a "backdoor," that could be used for memory manipulation (read/write RAM and Flash), MAC address spoofing (device impersonation), and LMP/LLCP packet injection. Espressif has not publicly documented these commands, so either they weren't meant to be accessible, or they were left in by mistake. Thanks to Slashdot reader ZipNada for sharing the news.

Butterflies "are vanishing from U.S. landscapes at an alarming rate," reports CBS News: A comprehensive study, published Thursday in the journal Science, found that 22% of butterflies in the United States disappeared between 2000 and 2020... The researchers behind the Science study used data from more than 12.6 million butterflies spanning 342 individual species, drawing from 76,000 surveys across 35 nationwide monitoring programs. Funded by the U.S. Geological Survey, the study was the first to integrate such a vast dataset, its authors said. The findings revealed that 33% of butterfly species have experienced significant population declines over the past two decades, with 107 out of the 342 species examined losing more than half of their population — including 22 species that declined by more than 90%. Meanwhile, only 3% of species showed population increases... Ultimately, the butterfly decline is part of a larger global trend of insect population loss, with insects declining by about 1-2% annually, the study's authors said. Butterflies play an essential role in ecosystems, pollinating flowers, crops, and other plants. Their decline could have far-reaching impacts on plant reproduction and the health of ecosystems. Just three months ago the U.S. Fish and Wildlife Service said America's western migratory populations of monarch butterflies had declined by more than 95% since the 1980s, putting them "at greater than 99% chance of extinction by 2080." (America's eastern migratory population were estimated to have declined by approximately 80%.) This latest study found that one factor is climate change, according to CBS News, which reduces food sources, disrupts breeding cycles and increases habitat stress. (Another factor is pesticide use, which fortunately can be adjusted with various policy interventions and farming practices.) And one of the study's co-authors tells CBS News that "the things we do in our own backyards actually make a difference." They recommend allowing backyard to "grow wild" with native plants (and reducing pesticide use) — even creating "habitat spaces" for insects like small piles of brush. "Even simple actions — like leaving a strip of wildflowers or planting species that support pollinators — can provide crucial resources for butterflies and other insects."

Sam Bankman-Fried — one of the largest donors to the Democratic Party — "was convicted of fraud, sentenced to 25 years in prison and mostly went silent," reports the Wall Street Journal. "Until recently..." Now, from behind bars at the Metropolitan Detention Center in Brooklyn, Bankman-Fried is orchestrating an extraordinary public-relations blitz that looks very much like a campaign to make the most audacious trade of his career: support for President Trump's agenda in return for a presidential pardon... There is little downside to Bankman-Fried's long-shot effort to secure a pardon. As the appeal that he filed last year works its way through the courts, Bankman-Fried, 33, is staring down a prison sentence that could extend until his 50s... The crowning touch of his campaign came on Thursday, when Bankman-Fried gave a jailhouse interview to "The Tucker Carlson Show," which was released on social-media channels including X and YouTube. Appearing on video in a brown jumpsuit, he criticized Washington bureaucrats and crypto regulators — and suggested that he went to prison out of political retribution... [Carlson's title for the interview? "Sam Bankman-Fried on Life in Prison With Diddy, and How Democrats Stole His Money and Betrayed Him."] The interview hadn't been approved by the Federal Bureau of Prisons, according to a person familiar with the matter. Bankman-Fried spoke with Carlson through a link that is typically used by inmates to communicate with their lawyers, the person said. After the interview, Bankman-Fried was placed in solitary confinement, but he was out by Friday afternoon, according to a person familiar with the matter... Bankman-Fried is trying to highlight in media appearances and in any interaction with Trump's team that FTX customers are set to be made whole with interest through the bankruptcy proceedings — at least in dollar terms. Many of those creditors remain furious that they missed out on bitcoin's rally since November 2022. Bankman-Fried "wants to set the record straight on his political beliefs, which he believes have been misconstrued," according to the article. "While he has given heavily to Democrats, he has also donated to Republican causes, including the contribution of millions to a group supporting Senator Mitch McConnell." But the New York Times, citing "people with knowledge" of his pardon-seeking efforts, reported that "So far, the push does not appear to have gained traction."

The Open Source Initiative's Board of Directors election "has become embroiled in controversy..." writes Steven J. Vaughan-Nichols at The New Stack. "The real issue is the community's opposition to the open source AI definition (OSAID), which the organization released last October," he adds — but "the election process has been criticized because the OSI has refused to accept the candidacy of Debian developer Luke Faraone, citing a missed application deadline." Faraone claims they submitted their application around 9 p.m. PST on Feb. 17, while the OSI maintains the deadline was 11:59 p.m. UTC (3:59 p.m. PST) on the same day. The dispute has raised a firestorm about the clarity of communication regarding deadlines and time zones. Critics argue that the deadline's time zone was not clearly specified on the OSI's public-facing website. Tracy Hinds, chair of OSI, acknowledged this oversight but stated that full members received multiple emails with the correct time zone information. "Everyone who is qualified to run for elections (full members of OSI) received emails with the time zone," wrote Hinds, in an email to The New Stack. "The public-facing web page did not have the time zone, and we've now updated it for clarity going forward. "Extending the deadline would be unfair to the other candidates...." On LinkedIn, Bruce Perens, one of the OSI's founders wrote, "Open Source Initiative invents rule at the last minute to deny opposition candidate's nomination for their board election." There are three board sets up for election in March, the article points out. "Two well-known figures in the open source world — Richard Fontana, Red Hat's principal commercial counsel and a former OSI board member, and [Bradley] Kuhn, policy fellow and hacker-in-residence at the Software Freedom Conservancy — are running on a joint platform of repealing the open source AI definition." In a blog post Faraone promised a similar platform (also supporting a repeal of the definition) — had their candidacy not been rejected.

Equuleus42 (Slashdot reader #723) brings word that the Electronic Frontier Foundation (EFF) is sharing a new tool for fighting back against cellphone surveillance by Stingray cell-site simulators. Android Authority reports: "Rayhunter" uses an open-source software package designed to look for evidence of IMSI catchers in action, running on an old Orbic Speed RC400L mobile hotspot. The great thing about that choice is that you can pick one up for practically nothing — we're seeing them listed for barely over $10 on Amazon, and you can find them even cheaper on eBay. There's an installation script for Macs and Linux to automate getting set up, but once the Orbic is flashed with the Rayhunter software, it should be ready go, collecting data about sketchy-looking "cell towers" it picks up. Right now, much of the use of IMSI catchers is still shrouded in mystery, with the groups who regularly employ them extremely hesitant to disclose their methods. As a result, a big focus of this EFF project is just getting more info on how and where these are actually used, giving protestors a better sense of the steps they'll need to take if they want to protect their privacy.
