Stingless bees from the Amazon have become the first insects to be granted legal rights anywhere in the world, in a breakthrough supporters hope will be a catalyst for similar moves to protect bees elsewhere. From a report: It means that across a broad swathe of the Peruvian Amazon, the rainforest's long-overlooked native bees -- which, unlike their cousins the European honeybees, have no sting -- now have the right to exist and to flourish. Cultivated by Indigenous peoples since pre-Columbian times, stingless bees are thought to be key rainforest pollinators, sustaining biodiversity and ecosystem health.

But they are faced with a deadly confluence of climate change, deforestation and pesticides, as well as competition from European bees, and scientists and campaigners have been racing against time to get stingless bees on international conservation red lists. Constanza Prieto, Latin American director at the Earth Law Center, who was part of the campaign, said: "This ordinance marks a turning point in our relationship with nature: it makes stingless bees visible, recognises them as rights-bearing subjects, and affirms their essential role in preserving ecosystems."

An anonymous reader shared this report from the BBC: There is growing controversy over recent evidence suggesting that a mysterious force known as dark energy might be changing in a way that challenges our current understanding of time and space. An analysis by a South Korean team has hinted that, rather than the Universe continuing to expand, galaxies could be pulled back together by gravity, ending in what astronomers call a "Big Crunch".

The scientists involved believe that they may be on the verge of one of the biggest discoveries in astronomy for a generation. Other astronomers have questioned these findings, but these critics have not been able to completely dismiss the South Korean team's assertions...

The controversy began in March with unexpected results from an instrument on a telescope in the Arizona desert called the Dark Energy Spectroscopic Instrument (Desi)... The data hinted that acceleration of the galaxies had changed over time, something not in line with the standard picture, according to Prof Ofer Lehav of University College London, who is involved with the Desi project. "Now with this changing dark energy going up and then down, again, we need a new mechanism. And this could be a shake up for the whole of physics," he says. Then in November the Royal Astronomical Society (RAS) published research from a South Korean team that seems to back the view that the weirdness of dark energy is weirder still.

Prof Young Wook Lee of Yonsei University in Seoul and his team went back to the kind of supernova data that first revealed dark energy 27 years ago. Instead of treating these stellar explosions as having one standard brightness, they adjusted for the ages of the galaxies they came from and worked out how bright the supernovas really were. This adjustment showed that not only had dark energy changed over time, but, shockingly, that the acceleration was slowing down... If, as Prof Lee's results suggest, the force that is pushing galaxies away from each other — dark energy — is weakening, then one possibility is that it becomes so weak that gravity begins to pull the galaxies back together.

An anonymous reader shared this report from the Associated Press: Two NATO-nation intelligence services suspect Russia is developing a new anti-satellite weapon to target Elon Musk's Starlink constellation with destructive orbiting clouds of shrapnel, with the aim of reining in Western space superiority that has helped Ukraine on the battlefield. Intelligence findings seen by The Associated Press say the so-called "zone-effect" weapon would seek to flood Starlink orbits with hundreds of thousands of high-density pellets, potentially disabling multiple satellites at once but also risking catastrophic collateral damage to other orbiting systems.

Analysts who haven't seen the findings say they doubt such a weapon could work without causing uncontrollable chaos in space for companies and countries, including Russia and its ally China, that rely on thousands of orbiting satellites for communications, defense and other vital needs. Such repercussions, including risks to its own space systems, could steer Moscow away from deploying or using such a weapon, analysts said. "I don't buy it. Like, I really don't," said Victoria Samson, a space-security specialist at the Secure World Foundation who leads the Colorado-based nongovernmental organization's annual study of anti-satellite systems. "I would be very surprised, frankly, if they were to do something like that." [Later they suggested the research might just be experimental.]

But the commander of the Canadian military's Space Division, Brig. Gen. Christopher Horner, said such Russian work cannot be ruled out in light of previous U.S. allegations that Russia also has been pursuing an indiscriminate nuclear, space-based weapon. "I can't say I've been briefed on that type of system. But it's not implausible," he said... The French military's Space Command said in a statement to the AP that it could not comment on the findings but said, "We can inform you that Russia has, in recent years, been multiplying irresponsible, dangerous, and even hostile actions in space."
The article also points out that this month Russia "said it has fielded a new ground-based missile system, the S-500, which is capable of hitting low-orbit targets..."

An astrophysicist at the University of Rochester writes that "many" of his colleagues in physics "have come to believe that a mystery is unfolding in every microbe, animal, and human." And it's a mystery that:

- "Challenges basic assumptions physicists have held for centuries"
- "May even help redefine the field for the next generation"
- "Could answer essential questions about AI."

In short, while physicists have favored a "reductionist" philosophy about the fundamental laws controlling the universe (energy, mattery, space, and time), "long-promised 'theories of everything' such as string theory, have not borne significant fruit: There are, however, ways other than reductionism to think about what's fundamental in the universe. Beginning in the 1980s, physicists (along with researchers in other fields) began developing new mathematical tools to study what's called "complexity" — systems in which the whole is far more than the sum of its parts. The end goal of reductionism was to explain everything in the universe as the result of particles and their interactions. Complexity, by contrast, recognizes that once lots of particles come together to produce macroscopic things — such as organisms — knowing everything about particles isn't enough to understand reality...

Physicists have always been good at capturing the essential aspects of a system and casting those essentials in the language of mathematics... Now those skills must be brought to bear on an age-old question that is only just getting its proper due: What is life? Using these skills, physicists — working together with representatives of all the other disciplines that make up complexity science — may crack open the question of how life formed on Earth billions of years ago and how it might have formed on the distant alien worlds we can now explore with cutting-edge telescopes. Just as important, understanding why life, as an organized system, is different at a fundamental level from all the other stuff in the universe may help astronomers design new strategies for finding it in places bearing little resemblance to Earth. Analyzing life — no matter how alien — as a self-organizing information-driven system may provide the key to detecting biosignatures on planets hundreds of light-years away.

Closer to home, studying the nature of life is likely essential to fully understanding intelligence — and building artificial versions. Throughout the current AI boom, researchers and philosophers have debated whether and when large language models might achieve general intelligence or even become conscious — or whether, in fact, some already have. The only way to properly assess such claims is to study, by any means possible, the sole agreed-upon source of general intelligence: life. Bringing the new physics of life to problems of AI may not only help researchers predict what software engineers can build; it may also reveal the limits of trying to capture life's essential character in silicon.

The first-ever commercial rocket launched at Brazil's Alcantara Space Center crashed soon after liftoff late earlier this week, dealing a blow to Brazilian aerospace ambitions and shares of South Korean satellite launch company Innospace. From a report: The rocket began its vertical trajectory as planned after liftoff [Monday] at 10:13 p.m. local time (0113 GMT) but fell to the ground after something went wrong 30 seconds into its flight, Innospace CEO Kim Soo-jong said in a letter to shareholders.

The craft crashed within a pre-designated safety zone and did not harm anyone, he said. Brazil's air force said firefighters were sent to analyze the wreckage and impact zone. "We are deeply sorry that we failed to meet the expectations of our shareholders who supported our first commercial launch," the CEO wrote in the letter, which was posted on the company's website on December 23. Innospace shares plunged nearly 29% in Seoul in its biggest daily drop and heaviest daily trading volume since its July 2024 listing.

NASA Administrator Jared Isaacman, who was confirmed by the Senate just last week after a turbulent nomination process that stretched across most of 2025, said Friday that the United States will return to the moon within President Donald Trump's second term. Isaacman made the comments during an interview on CNBC, calling Trump's recommitment to lunar exploration key to unlocking what he described as an "orbital economy." He said: "We want to have that opportunity to explore and realize the scientific, economic and national security potential on the moon," he said.

The potential opportunities include establishing space data centers and infrastructure on the moon, as well as mining Helium-3, a rare gas embedded in the lunar surface that could serve as fuel for fusion power. NASA is currently working on its Artemis campaign alongside SpaceX, Blue Origin, and Boeing. Trump's One Big Beautiful Bill Act allocated $9.9 billion to the agency earlier this year.

The Artemis II mission, NASA's first crewed test flight using the Space Launch System rocket and Orion spacecraft, is expected to launch in the near future. SpaceX is contracted to build the lunar landing system for the subsequent Artemis III mission. Isaacman was first nominated by Trump in December 2024 but had his nomination pulled in May over unspecified "prior associations." Trump renominated him in November.

With NASA's Mars Sample Return mission delayed into the 2030s, engineers are certifying the Perseverance rover to keep operating for many more years while it continues collecting and safeguarding Martian rock samples. Ars Technica reports: The good news is that the robot, about the size of a small SUV, is in excellent health, according to Steve Lee, Perseverance's deputy project manager at NASA's Jet Propulsion Laboratory (JPL). "Perseverance is approaching five years of exploration on Mars," Lee said in a press briefing Wednesday at the American Geophysical Union's annual fall meeting. "Perseverance is really in excellent shape. All the systems onboard are operational and performing very, very well. All the redundant systems onboard are available still, and the rover is capable of supporting this mission for many, many years to come."

The rover's operators at JPL are counting on sustaining Perseverance's good health. The rover's six wheels have carried it a distance of about 25 miles, or 40 kilometers, since landing inside the 28-mile-wide (45-kilometer) Jezero Crater in February 2021. That is double the original certification for the rover's mobility system and farther than any vehicle has traveled on the surface of another world. Now, engineers are asking Perseverance to perform well beyond expectations. An evaluation of the rover's health concluded it can operate until at least 2031. The rover uses a radioactive plutonium power source, so it's not in danger of running out of electricity or fuel any time soon. The Curiosity rover, which uses a similar design, has surpassed 13 years of operations on Mars.

There are two systems that are most likely to limit the rover's useful lifetime. One is the robotic arm, which is necessary to collect samples, and the other is the rover's six wheels and the drive train that powers them. "To make sure we can continue operations and continue driving for a long, long way, up to 100 kilometers (62 miles), we are doing some additional testing," Lee said. "We've successfully completed a rotary actuator life test that has now certified the rotary system to 100 kilometers for driving, and we have similar testing going on for the brakes. That is going well, and we should finish those early part of next year."

Russia plans to put a nuclear power plant on the moon in the next decade to supply its lunar space programme and a joint Russian-Chinese research station, as major powers rush to explore the earth's only natural satellite. Reuters: Ever since Soviet cosmonaut Yuri Gagarin became the first human to go into space in 1961, Russia has prided itself as a leading power in space exploration, but in recent decades it has fallen behind the United States and, increasingly, China. Russia's ambitions suffered a massive blow in August 2023 when its unmanned Luna-25 mission smashed into the surface of the moon while attempting to land, and Elon Musk has revolutionised the launch of space vehicles - once a Russian speciality.

Russia's state space corporation, Roscosmos, said in a statement that it planned to build a lunar power plant by 2036 and signed a contract with the Lavochkin Association aerospace company to do it. Roscosmos did not say explicitly that the plant would be nuclear but it said the participants included Russian state nuclear corporation Rosatom and the Kurchatov Institute, Russia's leading nuclear research institute. Roscosmos said the purpose of the plant was to power Russia's lunar programme, including rovers, an observatory and the infrastructure of the joint Russian-Chinese International Lunar Research Station.

Longtime Slashdot reader MrFreak shares a public radio interview from 2015 discussing artificial intelligence as inference over abstract inputs, along with scaling limits, automation, and governance models, where for-profit engines are constrained by nonprofit oversight: Recorded months before OpenAI was founded, the conversation treats intelligence as math plus incentives rather than something mystical, touching on architectural bottlenecks, why "reasoning" may not simply emerge from brute force, labor displacement, and institutional design for advanced AI systems. Many of the themes align closely with current debates around large language models and AI governance.

The recording was revisited following recent remarks by Sergey Brin at Stanford, where he acknowledged that despite Google's early work on Transformers, institutional hesitation and incentive structures limited how aggressively the technology was pursued. The interview provides an earlier, first-principles perspective on how abstraction, scaling, and organizational design might interact once AI systems begin to compound.

joshuark shares a report from Ars Technica: For the better part of two months last year, most of us had no idea how serious the problems were with Boeing's Starliner spacecraft docked at the International Space Station. A safety advisory panel found this uncertainty also filtered through NASA's workforce. [...] The Starliner capsule was beset by problems with its maneuvering thrusters and pernicious helium leaks on its 27-hour trip from the launch pad to the ISS. For a short time, Starliner commander Wilmore lost his ability to control the movements of his spacecraft as it moved in for docking at the station in June 2024. Engineers determined that some of the thrusters were overheating and eventually recovered most of their function, allowing Starliner to dock with the ISS. [...]

Throughout that summer, managers from NASA and Boeing repeatedly stated that the spacecraft was safe to bring Wilmore and Williams home if the station needed to be evacuated in an emergency. But officials on the ground ordered extensive testing to understand the root of the problems. Buried behind the headlines, there was a real chance NASA managers would decide -- as they ultimately did -- not to put astronauts on Boeing's crew capsule when it was time to depart the ISS. [...] It would have been better, [Charlie Precourt, a former space shuttle commander and now a member of NASA's Aerospace Safety Advisory Panel (ASAP)] and other panel members said Friday, if NASA made a formal declaration of an in-flight "mishap" or "high visibility close call" soon after the Starliner spacecraft's troubled rendezvous with the ISS. Such a declaration would have elevated responsibility for the investigation to NASA's safety office. [...]

After months of testing and analysis, NASA officials were unsure if the thruster problems would recur on Starliner's flight home. They decided in August 2024 to return the spacecraft to the ground without the astronauts, and the capsule safely landed in New Mexico the following month. The next Starliner flight will carry only cargo to the ISS. The safety panel recommended that NASA review its criteria and processes to ensure the language is "unambiguous" in requiring the agency to declare an in-flight mishap or a high-visibility close call for any event involving NASA personnel "that leads to an impact on crew or spacecraft safety."

Tony Isaac shares a report from NPR: The U.S. government calculates the country's official time using more than a dozen atomic clocks at a federal facility northwest of Denver. But when a destructive windstorm knocked out power to the National Institute of Standards and Technology (NIST) laboratory in Boulder on Wednesday and a backup generator subsequently failed, time ever so slightly slowed down. The lapse "resulted in NIST UTC [universal coordinated time] being 4.8 microseconds slower than it should have been," NIST spokesperson Rebecca Jacobson said in an email. [...]

Since 2007, the official time of the U.S. has been determined by the commerce secretary, who oversees NIST, along with the U.S. Navy. The national time standard is known as NIST UTC. (Somewhat confusingly, UTC itself is a separate, global time standard to which the U.S. and other countries contribute measurements.) NIST currently calculates the standard using a weighted average of the readings of 16 atomic clocks situated across the Boulder campus. Atomic clocks, including hydrogen masers and cesium beam clocks, rely on the natural resonant frequencies of atoms to tell time with extremely high accuracy.

All of the atomic clocks continued ticking through the power outage last week thanks to their battery backup systems, according to NIST supervisory research physicist Jeff Sherman. What failed was the connection between some of the clocks and NIST's measurement and distribution systems, he said. Some critical operations staff who were still on site following the severe weather were able to restore backup power by activating a diesel generator the team had kept in reserve, Sherman said.

An anonymous reader shared this report from the Washington Post. (Alternate URL here): The American patrol satellite had the targets in its sights: two recently launched Chinese spacecraft flying through one of the most sensitive neighborhoods in space. Like any good tactical fighter, the American spacecraft, known as USA 270, approached from behind, so that the sun would be at its back, illuminating the quarry.

But then one of the Chinese satellites countered by slowing down. As USA 270 zipped by, the Chinese satellite dropped in behind its American pursuer, like Maverick's signature "hit-the-brakes" move in the movie "Top Gun." The positions reversed, U.S. officials controlling their spacecraft from Earth were forced to plot their next move. The encounter some 22,000 miles above Earth in 2022 was never acknowledged publicly by the Pentagon or Beijing. Happening out of sight and little noticed except by space and defense specialists, this kind of orbital skirmishing has become so common that defense officials now refer to it as "dogfighting..."

Much of the "dogfighting" activity in space is simply for spying, defense analysts say, with specifics largely classified — snapping photos of each other's satellites to learn what kind of systems are on board and their capabilities. They monitor the signals and data emitted by satellites, listening to communications between space and the ground. Many can even jam those signals or interfere with orbiting craft that provide missile warnings, spy or relay critical information to troops... Traditionally, once a satellite was in orbit, it largely stayed on a fixed path, its operators reluctant to burn precious fuel. But now, the Pentagon and its adversaries, notably China and Russia, are launching satellites designed to fly in more dynamic ways that resemble aircraft — banking hard, slowing down, speeding up, even flying in tandem.

"Traditionally satellites weren't designed to fight, and they weren't designed to protect themselves in a fight," said Clinton Clark, the chief growth officer of ExoAnalytic Solutions, a company that monitors activity in space. "That is all changing now."
"Unlike dogfights between fighter jets, the jockeying-for-position encounters in orbit take place over several hours, even days," the article points out.

But it also notes that recently Germany's defense minister "complained about a Russian satellite that had been flying close to a commercial communications satellite used by the German military. 'They can jam, blind, manipulate or kinetically disrupt satellites,' he said."

Longtime Slashdot reader schwit1 shares a report from Space.com: Astronomers have made a truly mind-boggling discovery using the James Webb Space Telescope (JWST): a runaway black hole 10 million times larger than the sun, rocketing through space at a staggering 2.2 million miles per hour (1,000 kilometers per second). That not only makes this the first confirmed runaway supermassive black hole, but this object is also one of the fastest-moving bodies ever detected, rocketing through its home, a pair of galaxies named the "Cosmic Owl," at 3,000 times the speed of sound at sea level here on Earth. If that isn't astounding enough, the black hole is pushing forward a literal galaxy-sized "bow-shock" of matter in front of it, while simultaneously dragging a 200,000 light-year-long tail behind it, within which gas is accumulating and triggering star formation. "It boggles the mind!" discovery team leader Pieter van Dokkum of Yale University told Space.com. "The forces that are needed to dislodge such a massive black hole from its home are enormous. And yet, it was predicted that such escapes should occur!"

"This is the only black hole that has been found far away from its former home," van Dokkum said. "That made it the best candidate [for a] runaway supermassive black hole, but what was missing was confirmation. All we really had was a streak that was difficult to explain in any other way. With the JWST, we have now confirmed that there is indeed a black hole at the tip of the streak, and that it is speeding away from its former host."

The research is currently available as a pre-peer-reviewed paper on arXiv.

More carbon dioxide in the environment is making food more calorific but less nutritious -- and also potentially more toxic, a study has found. From a report: Sterre ter Haar, a lecturer at Leiden University in the Netherlands, and other researchers at the institution created a method to compare multiple studies on plants' responses to increased CO2 levels. The results, she said, were a shock: although crop yields increase, they become less nutrient-dense. While zinc levels in particular drop, lead levels increase.

"Seeing how dramatic some of the nutritional changes were, and how this differed across plants, was a big surprise," she told the Guardian. "We aren't seeing a simple dilution effect but rather a complete shift in the composition of our foods... This also raises the question of whether we should adjust our diets in some way, or how we grow or produce our food."

While scientists have been looking at the effects of more CO2 in the atmosphere on plants for a decade, their work has been difficult to compare. The new research established a baseline measurement derived from the observation that the gas appears to have a linear effect on growth, meaning that if the CO2 level doubles, so does the effect on nutrients. This made it possible to compare almost 60,000 measurements across 32 nutrients and 43 crops, including rice, potatoes, tomatoes and wheat.

alternative_right shares a report from ScienceAlert: A new study adds to the growing body of evidence that swearing can help us unleash our inner strength, improving physical performance, it seems, by helping people break through certain psychological barriers. [...] [Psychology researcher Richard Stephens of Keele University in the UK] and his colleagues at Keele and the University of Alabama wanted to test whether swearing could not only improve physical performance, as they had done in previous research, but also see whether it does so by changing a person's psychology in the moment, especially when it comes to letting go of inhibitions.

Eighty-eight participants, aged 18 to 65, all in good enough shape to exert themselves physically, were recruited at a university campus to participate in the first experiment. They each selected a pair of words based on the following prompts: a swear word you might utter after bumping your head, and a neutral word you might use to describe a table. Then, they undertook a chair push-up, which involves sitting in a chair and, holding each side of the seat, using your arms to lift your entire body weight (bottom off the chair, feet off the floor). [...]

Both experiments suggested that swearing offers an advantage in physical performance, with participants achieving longer chair push-up hold times as they repeated their foul-mouthed mantras. Scores for positive emotion, humor, distraction, and novelty were also elevated in the swearing tests, which suggests invoking their favorite four-letter word might enable people to transition into more action-oriented states, and perhaps actually enjoy their workout more. The research is published in American Psychologist.

Longtime Slashdot reader schwit1 shares a report from Ars Technica: Every other week, it seems, a new Chinese launch company pops up with a rocket design and a plan to reach orbit within a few years. For a long time, the majority of these companies revealed designs that looked a lot like SpaceX's Falcon 9 rocket. The first of these copy cats, the medium-lift Zhuque-3 rocket built by LandSpace, launched earlier this month. Its primary mission was nominal, but the Zhuque-3 rocket failed its landing attempt, which is understandable for a first flight. Doubtless there will be more Chinese Falcon 9-like rockets making their debut in the near future. However, over the last year, there has been a distinct change in announcements from China when it comes to new launch technology. Just as SpaceX is seeking to transition from its workhorse Falcon 9 rocket -- which has now been flying for a decade and a half -- to the fully reusable Starship design, so too are Chinese companies modifying their visions.

The trend began with the Chinese government. In November 2024 the government announced a significant shift in the design of its super-heavy lift rocket, the Long March 9. Instead of the previous design, a fully expendable rocket with three stages and solid rocket boosters strapped to the sides, the country's state-owned rocket maker revealed a vehicle that mimicked SpaceX's fully reusable Starship. Around the same time, a Chinese launch firm named Cosmoleap announced plans to develop a fully reusable "Leap" rocket within the next few years. An animated video that accompanied the funding announcement indicated that the company seeks to emulate the tower catch-with-chopsticks methodology that SpaceX has successfully employed.

But wait, there's more. In June a company called Astronstone said it too was developing a stainless steel, methane-fueled rocket that would also use a chopstick-style system for first stage recovery. Astronstone didn't even pretend to not copy SpaceX, saying it was "fully aligning its technical approach with Elon Musk's SpaceX." And then, on Friday, the state-aligned China.com reported that a company called "Beijing Leading Rocket Technology" took things a step further. It has named its vehicle "Starship-1," adding that the new rocket will have enhancements from AI and is billed as a "fully reusable AI rocket."

An anonymous reader quotes a report from the Guardian: The Massachusetts Institute of Technology (MIT) community is grieving after the "shocking" shooting death of the director of its plasma science and fusion center, according to officials. Nuno FG Loureiro, 47, had been shot multiple times at his home in the affluent Boston suburb of Brookline on Monday night when police said they received a call to investigate. Emergency responders brought Loureiro to a hospital, and the award-winning scientist was pronounced dead there Tuesday morning, the Norfolk county district attorney's office said in a statement.

The Boston Globe reported speaking with a neighbor of Loureiro who heard gunshots, found the academic lying on his back in the foyer of their building and then called for help alongside the victim's wife. The statement from the Norfolk district attorney's office said an investigation into Loureiro's slaying remained ongoing later Tuesday. But the agency did not immediately release any details about a possible suspect or motive in the killing, which gained widespread attention across academic circles, the US and in Loureiro's native Portugal.

Portugal's minster of foreign affairs announced Loureiro's death in a public hearing Tuesday, as CNN reported. Separately, MIT president Sally Kornbluth issued a university-wide letter expressing "great sadness" over the death of Loureiro, whose survivors include his wife. "This shocking loss for our community comes in a period of disturbing violence in many other places," said Kornbluth's letter, released after a weekend marred by deadly mass shootings at Brown University in Rhode Island -- about 50 miles away from MIT -- as well as on Australia's Bondi Beach. The letter concluded by providing a list of mental health resources, saying: "It's entirely natural to feel the need for comfort and support."

Longtime Slashdot reader schwit1 shares a report from Politico: The Senate on Wednesday approved Jared Isaacman for the top job at NASA -- an unprecedented comeback after President Donald Trump yanked his nomination this spring. Senators confirmed the billionaire private astronaut in a 67-30 vote. Trump renominated Isaacman for NASA administrator in November, after pulling his original nomination in May. He cited Isaacman's relationship with SpaceX CEO Elon Musk, with whom Trump had just had a falling out, as the rationale for his decision. Isaacman's surprise rebound followed months of political jockeying and help from high-profile figures in Trump's orbit. [...] Isaacman garnered backing from lawmakers during his hearing by confirming his support for NASA's Artemis moon-landing mission, a key prerogative for Capitol Hill. He also committed to instilling urgency at the space agency, citing China's space ambitions.

A comprehensive database built by scientists in Switzerland and Norway has catalogued 16,000 chemicals linked to plastic materials, and the findings paint a troubling picture of what Americans are actually eating when they prepare food in their kitchens. Of those 16,000 chemicals, more than 5,400 are considered hazardous to human health by government and industry standards, while just 161 are classified as not hazardous. The remaining 10,700-plus chemicals simply don't have enough data to determine their safety.

The chemicals enter food through multiple pathways. Black plastic utensils and trays often contain brominated flame retardants because they're made from recycled electronic waste. Nonstick pans and compostable plates frequently contain PFAS. One California study found phthalates in three-quarters of tested foods, and a Consumer Reports analysis last year detected BPA or similar chemicals in 79% of foods tested. According to CDC data, more than 90% of Americans have measurable levels of these chemicals in their bodies. A 10-fold increase in maternal levels of brominated flame retardants is associated with a 3.7-point IQ drop in children.

A new Arctic Report Card recap shows how the Arctic has transformed in just 20 years, warming about twice as fast as the global average and losing most of its oldest sea ice. It's also triggering cascading impacts from "Atlantification" to permafrost-driven "rusting rivers" and more destructive storms. Scientific American reports: The first Arctic Report Card was released by the National Oceanic and Atmospheric Administration in 2006. Since then the region has warmed twice as fast as the global average. About 95 percent of the oldest, thickest sea ice is gone -- "the sliver that remains is collected in an area north of Greenland. Even the central Arctic Ocean is becoming warmer and saltier, causing more ice melt and changing how much heat is released into the atmosphere in a way that affects weather patterns around the world. Those are just some of the stark changes 20 years have wrought. The findings were highlighted in the 2025 Arctic Report Card, released on Tuesday.

The Arctic Ocean is undergoing what scientists are calling "Atlantification" -- a process where warm, salty water from the Atlantic flows north, changing how waters of different temperatures and densities are layered in the Arctic, disrupting ecosystems and altering how heat moves from the water to the air. [...] The Arctic is simply becoming wetter, with more precipitation falling as rain instead of snow. June snow cover over the entire Arctic is half of what it was 60 years ago, the report found. Permafrost also continues to thaw, releasing once trapped carbon into the atmosphere and disgorging iron and other elements that have turned rivers and streams orange. These "rusting rivers," found in more than 200 watersheds, are more acidic than normal and have elevated levels of toxic metals that endanger local ecosystems. And as the permafrost thaws, the tundra of the Arctic biome is shrinking, and the boreal forest biome is creeping northward, disrupting ecosystems.

For decades, Parkinson's disease research has overwhelmingly focused on genetics -- more than half of all research dollars in the past two decades flowed toward genomic studies -- but a growing body of evidence now points to something far more mundane as a primary culprit: contaminated drinking water.

A landmark study by epidemiologist Sam Goldman compared Marines stationed at Camp Lejeune in North Carolina, where trichloroethylene (TCE) had contaminated the water supply for approximately 35 years, against those at Camp Pendleton in California, which has clean water. Marines exposed to TCE at Lejeune were 70% more likely to develop Parkinson's.

The latest research suggests only 10 to 15 percent of Parkinson's cases can be fully explained by genetics. Parkinson's rates in the US have doubled in the past 30 years -- a pattern inconsistent with an inherited genetic disease. The EPA moved to ban TCE in December 2024. The Trump administration moved to undo the ban in January.

"A SpaceX executive says a satellite deployed from a Chinese rocket risked colliding with a Starlink satellite," reports PC Magazine: On Friday, company VP for Starlink engineering, Michael Nicolls, tweeted about the incident and blamed a lack of coordination from the Chinese launch provider CAS Space. "When satellite operators do not share ephemeris for their satellites, dangerously close approaches can occur in space," he wrote, referring to the publication of predicted orbital positions for such satellites...

[I]t looks like one of the satellites veered relatively close to a Starlink sat that's been in service for over two years. "As far as we know, no coordination or deconfliction with existing satellites operating in space was performed, resulting in a 200 meter (656 feet) close approach between one of the deployed satellites and STARLINK-6079 (56120) at 560 km altitude," Nicolls wrote... "Most of the risk of operating in space comes from the lack of coordination between satellite operators — this needs to change," he added.
Chinese launch provider CAS Space told PCMag that "As a launch service provider, our responsibility ends once the satellites are deployed, meaning we do not have control over the satellites' maneuvers."

And the article also cites astronomer/satellite tracking expert Jonathan McDowell, who had tweeted that CAS Space's response "seems reasonable." (In an email to PC Magazine, he'd said "Two days after launch is beyond the window usually used for predicting launch related risks."

But "The coordination that Nicolls cited is becoming more and more important," notes Space.com, since "Earth orbit is getting more and more crowded." In 2020, for example, fewer than 3,400 functional satellites were whizzing around our planet. Just five years later, that number has soared to about 13,000, and more spacecraft are going up all the time. Most of them belong to SpaceX. The company currently operates nearly 9,300 Starlink satellites, more than 3,000 of which have launched this year alone.

Starlink satellites avoid potential collisions autonomously, maneuvering themselves away from conjunctions predicted by available tracking data. And this sort of evasive action is quite common: Starlink spacecraft performed about 145,000 avoidance maneuvers in the first six months of 2025, which works out to around four maneuvers per satellite per month. That's an impressive record. But many other spacecraft aren't quite so capable, and even Starlink satellites can be blindsided by spacecraft whose operators don't share their trajectory data, as Nicolls noted.

And even a single collision — between two satellites, or involving pieces of space junk, which are plentiful in Earth orbit as well — could spawn a huge cloud of debris, which could cause further collisions. Indeed, the nightmare scenario, known as the Kessler syndrome, is a debris cascade that makes it difficult or impossible to operate satellites in parts of the final frontier.

Cadmium zinc telluride (CZT), a hard-to-manufacture semiconductor produced by only a handful of companies, is enabling a quiet revolution in medical imaging, science, and security by delivering faster scans, lower radiation doses, and far more precise X-ray and gamma-ray detection. "You get beautiful pictures from this scanner," says Dr Kshama Wechalekar, head of nuclear medicine and PET. "It's an amazing feat of engineering and physics." The BBC reports: Kromek is one of just a few firms in the world that can make CZT. You may never have heard of the stuff but, in Dr Wechalekar's words, it is enabling a "revolution" in medical imaging. This wonder material has many other uses, such as in X-ray telescopes, radiation detectors and airport security scanners. And it is increasingly sought-after. Investigations of patients' lungs performed by Dr Wechalekar and her colleagues involve looking for the presence of many tiny blood clots in people with long Covid, or a larger clot known as a pulmonary embolism, for example.

The 1-million-pound scanner works by detecting gamma rays emitted by a radioactive substance that is injected into patients' bodies. But the scanner's sensitivity means less of this substance is needed than before: "We can reduce doses about 30%," says Dr Wechalekar. While CZT-based scanners are not new in general, large, whole-body scanners such as this one are a relatively recent innovation. CZT itself has been around for decades but it is notoriously difficult to manufacture. "It has taken a long time for it to develop into an industrial-scale production process," says Arnab Basu, founding chief executive of Kromek.

[...] The newly formed CZT, a semiconductor, can detect tiny photon particles in X-rays and gamma rays with incredible precision -- like a highly specialized version of the light-sensing, silicon-based image sensor in your smartphone camera. Whenever a high energy photon strikes the CZT, it mobilizes an electron and this electrical signal can be used to make an image. Earlier scanner technology used a two-step process, which was not as precise. "It's digital," says Dr Basu. "It's a single conversion step. It retains all the important information such as timing, the energy of the X-ray that is hitting the CZT detector -- you can create color, or spectroscopic images."

schwit1 shares a report from CBS News: perm from a donor who unknowingly carried a cancer-causing gene has been used to conceive nearly 200 babies across Europe, an investigation by 14 European public service broadcasters, including CBS News' partner network BBC News, has revealed. Some children conceived using the sperm have already died from cancer, and the vast majority of those who inherited the gene will develop cancer in their lifetimes, geneticists said. The man carrying the gene passed screening checks before he became a donor at the European Sperm Bank when he was a student in 2005. His sperm has been used by women trying to conceive for 17 years across multiple countries.

The cancer-causing mutation occurred in the donor's TP53 gene -- which prevents cells in the body from turning cancerous -- before his birth, according to the investigation. It causes Li Fraumeni syndrome, which gives affected people a 90% chance of developing cancers, particularly during childhood, as well as breast cancer in later life. Up to 20% of the donor's sperm contained the mutated TP53 gene. Any children conceived with affected sperm will have the dangerous mutation in every cell of their body. The affected donor sperm was discovered when doctors seeing children with cancers linked to sperm donation raised concerns at this year's European Society of Human Genetics.

At the time, 23 children with the genetic mutation had been discovered, out of 67 children linked to the donor. Ten of those children with the mutation had already been diagnosed with cancer. Freedom of Information requests submitted by journalists across multiple countries revealed at least 197 children were affected, though it is not known how many inherited the genetic mutation. More affected children could be discovered as more data becomes available.

NASA has lost contact with its MAVEN Mars orbiter after it passed behind Mars. When it remerged from behind the planet, the spacecraft never resumed communications. SpaceNews reports: MAVEN launched in November 2013 and entered orbit around Mars in September 2014. The spacecraft's primary science mission is to study the planet's upper atmosphere and interactions with the solar wind, including how the atmosphere escapes into space. That is intended to help scientists understand how the planet changes from early in its history, when it had a much thicker atmosphere and was warm enough to support liquid water on its surface.

MAVEN additionally serves as a communications relay, using a UHF antenna to link the Curiosity and Perseverance rovers on the Martian surface with the Deep Space Network. NASA's Mars Odyssey and Mars Reconnaissance Orbiter spacecraft also serve as communications relays for the rovers, but are both significantly older than MAVEN. The spacecraft has suffered some technical problems in the past, notably with its inertial measurement units (IMUs) used for navigation. In 2022, MAVEN switched to an "all-stellar" navigation system to minimize the use of the IMUs.

MAVEN has enough propellant to maintain its orbit through at least the end of the decade. NASA's fiscal year 2026 budget proposal, though, zeroed out funding for MAVEN, which cost $22.6 million to operate in 2024. MAVEN was one of several missions "operating well past the end of prime mission" the proposal would terminate, despite MAVEN's role as a communications relay.

alternative_right quotes a report from Phys.org: To teach robots how to become tomato pickers, Osaka Metropolitan University Assistant Professor Takuya Fujinaga, Graduate School of Engineering, programmed them to evaluate the ease of harvesting for each tomato before attempting to pick it. Fujinaga's new model uses image recognition paired with statistical analysis to evaluate the optimal approach direction for each fruit. The system involves image processing/vision of the fruit, its stems, and whether it is concealed behind another part of the plant. These factors inform robot control decisions and help it choose the best approach.

The model represents a shift in focus from the traditional 'detection/recognition' model to what Fujinaga calls a 'harvest-ease estimation.' "This moves beyond simply asking 'can a robot pick a tomato?' to thinking about 'how likely is a successful pick?', which is more meaningful for real-world farming," he explained. When tested, Fujinaga's new model demonstrated an 81% success rate, far above predictions. Notably, about a quarter of the successes were tomatoes that were successfully harvested from the right or left side that had previously failed to be harvested by a front approach. This suggested that the robot changed its approach direction when it initially struggled to pick the fruit. "This is expected to usher in a new form of agriculture where robots and humans collaborate," said Fujinaga. "Robots will automatically harvest tomatoes that are easy to pick, while humans will handle the more challenging fruits."

The findings are published in Smart Agricultural Technology.

A major scientific report published Tuesday argues that sending astronauts to Mars is justified by the quest to find life and conduct research that robots alone can't achieve. "We're searching for life on Mars," said Dava Newman, a professor in the Department of Aeronautics and Astronautics at Massachusetts Institute of Technology and co-chair of the committee that wrote the report. "The answer to the question 'are we alone' is always going to be 'maybe,' unless it becomes yes." Ars Technica reports: The report, two years in the making and encompassing more than 200 pages, was published by the National Academies of Sciences, Engineering, and Medicine. Essentially, the committee co-chaired by Newman and Linda T. Elkins-Tanton, director of the University of California, Berkeley Space Sciences Laboratory, was asked to identify the highest-priority science objectives for the first human missions to Mars. [...] "There's no turning back," Newman said. "Everyone is inspired by this because it's becoming real. We can get there. Decades ago, we didn't have the technologies. This would have been a study report."

The goal of the report is to help build a case for meaningful science to be done on Mars alongside human exploration. The report outlines 11 top-priority science objectives. [...] The committee also looked at different types of campaigns to determine which would be most effective for completing the science objectives noted above. The campaign most likely to be successful, they found, was an initial human landing that lasts 30 days, followed by an uncrewed cargo delivery to facilitate a longer 300-day crewed mission on the surface of Mars. All of these missions would take place in a single exploration zone, about 100 km in diameter, that featured ancient lava flows and dust storms.

Notably, the report also addresses the issue of planetary protection, a principle that aims to protect both celestial bodies (i.e., the surface of Mars) and visitors (i.e., astronauts) from biological contamination. [...] In recent years, NASA has been working with the International Committee on Space Research to design a plan in which human landings might occur in some areas of the planet, while other parts of Mars are left in "pristine" condition. The committee said this work should be prioritized to reach a resolution that will further the design of human missions to Mars. "NASA should continue to collaborate on the evolution of planetary protection guidelines, with the goal of enabling human explorers to perform research in regions that could possibly support, or even harbor, life," the report states.

In February, a six-month-old baby named KJ Muldoon became the first person ever to receive a CRISPR gene-editing treatment customized specifically for his unique genetic mutation, a milestone that researchers say marks a turning point in how medicine might approach the thousands of rare diseases that collectively affect 30 million Americans. Muldoon was born with a type of urea-cycle disorder that gives patients roughly a 50% chance of surviving infancy and typically requires a liver transplant; he is now a healthy 1-year-old who recently took his first steps.

The treatment's significance extends beyond one child. Scientists at UC Berkeley's Innovative Genomics Institute and the Children's Hospital of Philadelphia are now planning clinical trials that would use Muldoon's therapy as a template, tweaking the molecular "address" in the CRISPR system to target different mutations in other children with urea-cycle disorders. Last month, FDA officials Marty Makary and Vinay Prasad announced a new drug pathway designed to accelerate approvals for such personalized treatments -- a framework inspired in large part by Muldoon's case. Current gene-editing delivery mechanisms limit treatments to disorders in the blood and liver. Many families will still go without bespoke therapies.

An anonymous reader quotes a report from the Guardian: The journal Regulatory Toxicology and Pharmacology has formally retracted a sweeping scientific paper published in 2000 that became a key defense for Monsanto's claim that Roundup herbicide and its active ingredient glyphosate don't cause cancer. Martin van den Berg, the journal's editor in chief, said in a note accompanying the retraction that he had taken the step because of "serious ethical concerns regarding the independence and accountability of the authors of this article and the academic integrity of the carcinogenicity studies presented."

The paper, titled Safety Evaluation and Risk Assessment of the Herbicide Roundup and Its Active Ingredient, Glyphosate, for Humans, concluded that Monsanto's glyphosate-based weed killers posed no health risks to humans -- no cancer risks, no reproductive risks, no adverse effects on development of endocrine systems in people or animals. Regulators around the world have cited the paper as evidence of the safety of glyphosate herbicides, including the Environmental Protection Agency (EPA) in this assessment (PDF). [...]

In explaining the decision to retract the 25-year-old research paper, Van den Berg wrote: "Concerns were raised regarding the authorship of this paper, validity of the research findings in the context of misrepresentation of the contributions by the authors and the study sponsor and potential conflicts of interest of the authors." He noted that the paper's conclusions regarding the carcinogenicity of glyphosate were solely based on unpublished studies from Monsanto, ignoring other outside, published research. "The retraction of this study is a long time coming," said Brent Wisner, one of the lead lawyers in the Roundup litigation and a key player in getting the internal documents revealed to the public. Wisner said the study was the "quintessential example of how companies like Monsanto could fundamentally undermine the peer-review process through ghostwriting, cherrypicking unpublished studies, and biased interpretations."

"This garbage ghostwritten study finally got the fate it deserved,â Wisner added. "Hopefully, journals will now be more vigilant in protecting the impartiality of science on which so many people depend."

An anonymous reader quotes a report from the New York Times: Since online genealogy services began operating, millions of people have sent them saliva samples in hopes of learning about their family roots and discovering far-flung relatives. These services also appeal to law enforcement authorities, who have used them to solve cold case murders and to investigate crimes like the 2022 killing of four University of Idaho students. Crime-scene DNA submitted to genealogy sites has helped investigators identify suspects and human remains by first identifying relatives.

The use of public records and family-tree building is crucial to this technique, and its main tool has been the genealogy site Ancestry, which has vast amounts of individual DNA profiles and public records. More than 1,400 cases have been solved with the help of so-called genetic genealogy investigations, most of them with help from Ancestry. But a recent step taken by the site is now deterring many police agencies from employing this crime-solving technique.

In August, Ancestry revised the terms and conditions on its site to make it clear that its services were off-limits "for law enforcement purposes" without a legal order or warrant, which can be hard to get, because of privacy concerns. This followed the addition last year to the terms and conditions that the services could not be used for "judicial proceedings." Investigators say the implications are dire and will result in crucial criminal cases slowing or stalling entirely, denying answers to grieving families. "Everyone who does this work has depended on the records database that Ancestry controls," said David Gurney, who runs Ramapo College's Investigative Genetic Genealogy Center in New Jersey. "Without it, casework is going to be a lot slower, and there will be some cases that can't be resolved at all."

What triggered that Airbus emergency software recall? The BBC reports that Airbus's initial investigation into an aircraft's sudden drop in altitude linked it "to a malfunction in one of the aircraft's computers that controls moving parts on the aircraft's wings and tail." But that malfunction "seems to have been triggered by cosmic radiation bombarding the Earth on the day of the flight..."

The BBC believes radiation from space "could become a growing problem as ever more microchips run our lives." What Airbus says occurred on that JetBlue flight from Cancun to New Jersey was a phenomenon called a single-event upset, or bit flip. As the BBC has previously reported, these computer errors occur when high-speed subatomic particles from outer space, such as protons, smash into atoms in our planet's atmosphere. This can cause a cascade of particles to rain down through our atmosphere, like throwing marbles across a table. In rare cases, those fast-moving neutrons can strike computer electronics and disrupt tiny bits of data stored in the computer's memory, switching that bit — often represented as a 0 or 1 — from one state to another. "That can cause your electronics to behave in ways you weren't expecting," says Matthew Owens, professor of space physics at the University of Reading in the UK. Satellites are particularly affected by this phenomenon, he says. "For space hardware we see this quite frequently."

This is because the neutron flux — a measure of neutron radiation — rises the higher up in the atmosphere you go, increasing the chance of a strike hitting sensitive parts of the computer equipment on board. Aircraft are more vulnerable to this problem than computer equipment on the ground, although bit flips do occur at ground level, too. The increasing reliance of computers in fly-by-wire systems in aircraft, which use electronics rather than mechanical systems to control the plane in the air, also mean the risk posed by bit flips when they do occur is higher... Airbus told the BBC that it tested multiple scenarios when attempting to determine what happened to the 30 October 2025 JetBlue flight. In this case also, the company ruled out various possibilities except that of a bit flip. It is hard to attribute the incident to this for sure, however, because careering neutrons leave no trace of their activity behind, says Owens...

[Airbus's software update] works by inducing "rapid refreshing of the corrupted parameter so it has no time to have effect on the flight controls", Airbus says. This is, in essence, a way of continually sanitising computer data on these aircraft to try and ensure that any errors don't end up actually impacting a flight... As computer chips have become smaller, they have also become more vulnerable to bit flips because the energy required to corrupt tiny packets of data has got lower over time. Plus, more and more microchips are being loaded into products and vehicles, potentially increasing the chance that a bit flip could cause havoc. If nothing else, the JetBlue incident will focus minds across many industries on the risk posed to our modern, microchip-dependent lives from cosmic radiation that originates far beyond our planet.
Airbus said their analysis revealed "intense solar radiation" could corrupt data "critical to the functioning of flight control." But that explanation "has left some space weather scientists scratching their heads," adds the BBC.

Space.com explains: Solar radiation levels on Oct. 30 were unremarkable and nowhere near levels that could affect aircraft electronics, Clive Dyer, a space weather and radiation expert at University of Surrey in the U.K., told Space.com. Instead, Dyer, who has studied effects of solar radiation on aircraft electronics for decades, thinks the onboard computer of the affected jet could have been struck by a cosmic ray, a stream of high-energy particles from a distant star explosion that may have travelled millions of years before reaching Earth. "[Cosmic rays] can interact with modern microelectronics and change the state of a circuit," Dyer said. "They can cause a simple bit flip, like a 0 to 1 or 1 to 0. They can mess up information and make things go wrong. But they can cause hardware failures too, when they induce a current in an electronic device and burn it out."

Washington Post columnist Dana Milbank calls himself "a highly creative hypochondriac" — who just paid for an expensive MRI scan to locate abnormal spots as tiny as 2 millimeters.

He discusses the pros and cons of its "diffusion-weighted imaging" technology combined with the pattern recognition of AI, which theoretically "has the potential to save our lives by revealing budding cancers, silent aneurysms and other hidden would-be killers before they become deadly. " But the scans cost $2,500 a pop and insurance won't pay. Worse, for every cancer these MRIs find, they produce a slightly greater number of false positives that require a biopsy, with the potential for infection and bleeding and emotional distress. Even when the scans don't produce a false positive, they almost always come up with some vague and disconcerting abnormality.... Will we feel better after viewing our insides? Or will we become anxious about things we hadn't even thought to worry about?

Part of living has always been in the mystery, in not knowing what tomorrow will bring. Now, because of sophisticated imaging, genome sequencing and other revolutionary screening tools, we can have predictability, or at least the illusion of it. But do we want that? The American College of Radiology says we do not. Its still-current 2023 statement says there is not "sufficient evidence" to recommend full-body screening, cautioning that the scan could lead to needless testing and expense. But David Larson, chair of ACR's Commission on Quality and Safety, told me that could change as more data comes in. "When people ask me, 'Would you recommend it?' I would say it depends on your tolerance for ambiguity," he said, giving the example of somebody found to have a borderline aortic aneurysm who is advised to wait and monitor it. If "that won't keep you up at night, then I wouldn't necessarily recommend against it...."

About 1 in 20 gets that dreaded call. A study Prenuvo presented earlier this year of 1,011 participants found that 4.9 percent of scans required a follow-up biopsy. Of those, 2.2 percent were actually cancer, and the other 2.7 percent were false positives. Of the 22 cancers the scans caught, 86 percent of patients had no specific symptoms. But if finding something truly awful is rare, finding something abnormal is almost guaranteed. [Vikash Modi, Prenuvo's senior medical director of preventative medicine] said only 1 in 20 scans come back completely clean. The vast majority of patients wind up in the ambiguous realm where something may look suspicious but doesn't require urgent follow-up.
He opted for the cheaper $1,000 torso scan, which the senior medical director calls "our bread-and-butter area," since 17 of the 22 cancers detected in one Prenuvo study were in that area and is where they often find cancers that wouldn't be discovered until they were incurable like "that scary pancreatic stuff...."

Milbank's scan found 12 "abnormalities" included "a 2.5 mm pulmonary nodule in the right lower lobe" and "a 4.6 mm intraductal papillary mucinous neoplasm in the pancreatic tail" — but with 10 abnormalities labeled "minor" (and six being musculoskeletal wear-and-tear problems "I already knew about from the usual aches and pains".) Even the two "moderate" findings didn't sound that grim when I read on. The "indeterminant lesion" in my lung requires no follow-up, while the thing in my pancreas is "low-risk."... The "most interesting" finding was the pancreatic cyst, because, at this size and location, there's a 3 percent chance it will become cancerous in the next five years. But if annual follow-up scans of my pancreas (covered by insurance) show it's getting bigger, the cyst can be removed before it becomes cancer. For me, this made the MRI worthwhile. Sure, there was a 97 percent likelihood the cyst never would develop into a problem even if I hadn't learned about it. But now, with minimal inconvenience, I can eliminate that 3 percent risk of getting pancreatic cancer, the most lethal of major malignancies.

alternative_right shares a report from ScienceAlert: Engineers at Cornell University have created the blackest fabric on record, finding it absorbs 99.87 percent of all light that dares to illuminate its surface. [...] In this case, the Cornell researchers dyed a white merino wool knit fabric with a synthetic melanin polymer called polydopamine. Then, they placed the material in a plasma chamber, and etched structures called nanofibrils -- essentially, tiny fibers that trap light. "The light basically bounces back and forth between the fibrils, instead of reflecting back out -- that's what creates the ultrablack effect," says Hansadi Jayamaha, fiber scientist and designer at Cornell.

The structure was inspired by the magnificent riflebird (Ptiloris magnificus). Hailing from New Guinea and northern Australia, male riflebirds are known for their iridescent blue-green chests contrasted with ultrablack feathers elsewhere on their bodies. The Cornell material actually outperforms the bird's natural ultrablackness in some ways. The bird is blackest when viewed straight on, but becomes reflective from an angle. The material, on the other hand, retains its light absorption powers when viewed from up to 60 degrees either side. The findings have been published in the journal Nature Communications.

Despite predictions that AI would replace radiologists, healthcare systems worldwide are hiring more of them because AI tools enhance their work, create new oversight tasks, and increase imaging volumes rather than reducing workloads. "Put all that together with the context of an aging population and growing demand for imaging of all kinds, and you can see why Offiah and the Royal College of Radiologists are concerned about a shortage of radiologists, not their displacement," writes Financial Times authors John Burn-Murdoch and Sarah O'Connor. Amaka Offiah, who is a consultant pediatric radiologist and a professor in pediatric musculoskeletal imaging at the University of Sheffield in the UK, makes a prediction of her own: "AI will assist radiologists, but will not replace them. I could even dare to say: will never replace them." From the report: [A]lmost all of the AI tools in use by healthcare providers today are being used by radiologists, not instead of them. The tools keep getting better, and now match or outperform experienced radiologists even after factoring in false positives or negatives, but the fact that both human and AI remain fallible means it makes far more sense to pair them up than for one to replace the other. Two pairs of eyes can come to a quicker and more accurate judgment, one spotting or correcting something the other missed. And in high-stakes settings where the costs of a mistake can be astronomical, the downside risk from an error by a fully autonomous AI radiologist is huge. "I find this a fascinating demonstration of why even if AI really can do some of the most high-value parts of someone's job, it doesn't mean displacement (even of those few tasks let alone the job as a whole) is inevitable," concludes John. "Though I also can't help noticing a parallel to driverless cars, which were simply too risky to ever go fully autonomous until they weren't."

Sarah added: "I think the story of radiologists should be a reminder to technologists not to make sweeping assertions about the future of professions they don't intimately understand. If we had indeed stopped training radiologists in 2016, we'd be in a real mess today."

NASA's OSIRIS-REx samples from asteroid Bennu have revealed bio-essential sugars, a never-before-seen "space gum" polymer, and unusually high levels of supernova-origin dust. The findings bolster the RNA-world hypothesis, suggest complex organics formed early on Bennu's parent body, and show preserved presolar grains that escaped alteration for billions of years.

"All five nucleobases used to construct both DNA and RNA, along with phosphates, have already been found in the Bennu samples brought to Earth by OSIRIS-REx," said lead scientist Yoshihiro Furukawa of Tohoku University. "The new discovery of ribose means that all of the components to form the molecule RNA are present in Bennu."

The findings have been published in three new papers by the journals Nature Geosciences and Nature Astronomy. NASA also published a video on YouTube detailing the discovery.

An anonymous reader quotes a report from the Guardian: Almost three in 10 GPs in the UK are using AI tools such as ChatGPT in consultations with patients, even though it could lead to them making mistakes and being sued, a study reveals. The rapid adoption of AI to ease workloads is happening alongside a "wild west" lack of regulation of the technology, which is leaving GPs unaware which tools are safe to use. That is the conclusion of research by the Nuffield Trust thinktank, based on a survey of 2,108 family doctors by the Royal College of GPs about AI and on focus groups of GPs.

Ministers hope that AI can help reduce the delays patients face in seeing a GP. The study found that more and more GPs were using AI to produce summaries of appointments with patients, assisting their diagnosis of the patient's condition and routine administrative tasks. In all, 598 (28%) of the 2,108 survey respondents said they were already using AI. More male (33%) than female (25%) GPs have used it and far more use it in well-off than in poorer areas.

It is moving quickly into more widespread use. However, large majorities of GPs, whether they use it or not, worry that practices that adopt it could face "professional liability and medico-legal issues," and "risks of clinical errors" and problems of "patient privacy and data security" as a result, the Nuffield Trust's report says. [...] In a blow to ministerial hopes, the survey also found that GPs use the time it saves them to recover from the stresses of their busy days rather than to see more patients. "While policymakers hope that this saved time will be used to offer more appointments, GPs reported using it primarily for self-care and rest, including reducing overtime working hours to prevent burnout," the report adds.

Nature has retracted a headline-grabbing climate-economics study after critics found flawed data that massively inflated its predicted global economic collapse. The New York Times reports: The decision came after a team of economists noticed problems with the data for one country, Uzbekistan, that significantly skewed the results. If Uzbekistan were excluded, they found, the damages would look similar to earlier research (PDF). Instead of a 62 percent decline in economic output by 2100 in a world where carbon emissions continue unabated, global output would be reduced by 23 percent.

Of course, erasing more than 20 percent of the world's economic activity would still be a devastating blow to human welfare. The paper's detractors emphasize that climate change is a major threat, as recent meta analyses have found, and that more should be done to address it -- but, they say, unusual results should be treated skeptically. "Most people for the last decade have thought that a 20 percent reduction in 2100 was an insanely large number," said Solomon Hsiang, a professor of global environmental policy at Stanford University who co-wrote the critique published in August. "So the fact that this paper is coming out saying 60 percent is off the chart."

schwit1 shares a report from CNN: A private Chinese space firm successfully sent its Zhuque-3 rocket to orbit but failed in its historic attempt to re-land the rocket booster Wednesday -- the first such trial by a Chinese firm as the country's growing commercial space sector races to catch up with American rivals like SpaceX. The rocket entered orbit as planned, but its first stage did not successfully return to a landing site, instead crashing down, the company said in a statement.

"An anomaly occurred after the first-stage engine ignited during the landing phase, preventing a soft landing on the designated recovery pad," the statement said. "The debris landed at the edge of the recovery area, resulting in a failed recovery test." The team would "conduct a comprehensive review" and continue to "advance the verification and application of reusable rocket technology in future missions," the statement added. You can watch a video of the launch and subsequent crash here.

China's private launch firm LandSpace is preparing the debut flight of its Zhuque-3 rocket, aiming to become the country's first to land a reusable orbital-class booster using a Falcon-9-style return profile. Ars Technica reports: Liftoff could happen around 11 pm EST tonight (04:00 UTC Wednesday), or noon local time at the Jiuquan Satellite Launch Center in northwestern China. Airspace warning notices advising pilots to steer clear of the rocket's flight path suggest LandSpace has a launch window of about two hours. When it lifts off, the Zhuque-3 (Vermillion Bird-3) rocket will become the largest commercial launch vehicle ever flown in China. What's more, LandSpace will become the first Chinese launch provider to attempt a landing of its first stage booster, using the same tried-and-true return method pioneered by SpaceX and, more recently, Blue Origin in the United States.

Construction crews recently finished a landing pad in the remote Gobi Desert, some 240 miles (390 kilometers) southeast of the launch site at Jiuquan. Unlike US spaceports, the Jiuquan launch base is located in China's interior, with rockets flying over land as they climb into space. When the Zhuque-3 booster finishes its job of sending the rocket toward orbit, it will follow an arcing trajectory toward the recovery zone, firing its engines to slow for landing about eight-and-a-half minutes after liftoff. At least, that's what is supposed to happen. LandSpace officials have not made any public statements about the odds of a successful landing -- or, for that matter, a successful launch... UPDATE: Chinese Reusable Booster Explodes During First Orbital Test

Bruce66423 shares a report from the Los Angeles Times: Tattoo ink doesn't just sit inertly in the skin. New research shows it moves rapidly into the lymphatic system, where it can persist for months, kill immune cells, and even disrupt how the body responds to vaccines. Scientists in Switzerland used a mouse model to trace what happens after tattooing. Pigments drained into nearby lymph nodes within minutes and continued to accumulate for two months, triggering immune-cell death and sustained inflammation. The ink also weakened the antibody response to Pfizer Inc. and BioNTech SE's COVID vaccine when the shot was administered in tattooed skin. In contrast, the same inflammation appeared to boost responses to an inactivated flu vaccine. "This work represents the most extensive study to date regarding the effect of tattoo ink on the immune response and raises serious health concerns associated with the tattooing practice," the researchers said. "Our work underscores the need for further research to inform public health policies and regulatory frameworks regarding the safety of tattoo inks."

The findings have been published in the journal Proceedings of the National Academy of Sciences.

An anonymous reader quotes a report from the New York Times: The San Francisco city attorney filed on Tuesday the nation's first government lawsuit against food manufacturers over ultraprocessed fare (source may be paywalled; alternative source), arguing that cities and counties have been burdened with the costs of treating diseases that stem from the companies' products. David Chiu, the city attorney, sued 10 corporations that make some of the country's most popular food and drinks. Ultraprocessed products now comprise 70 percent of the American food supply and fill grocery store shelves with a kaleidoscope of colorful packages. Think Slim Jim meat sticks and Cool Ranch Doritos. But also aisles of breads, sauces and granola bars marketed as natural or healthy.

It is a rare issue on which the liberal leaders in San Francisco City Hall are fully aligned with the Trump administration, which has targeted ultraprocessed foods as part of its Make America Healthy Again mantra. Mr. Chiu's lawsuit, which was filed in San Francisco Superior Court on behalf of the State of California, seeks unspecified damages for the costs that local governments bear for treating residents whose health has been harmed by ultraprocessed food. The city accuses the companies of "unfair and deceptive acts" in how they market and sell their foods, arguing that such practices violate the state's Unfair Competition Law and public nuisance statute. The city also argues the companies knew that their food made people sick but sold it anyway.

According to the article, Ukraine is "exploring alternative European satellite providers in response, seeking more secure and controllable communications infrastructure for military operations." While switching to another satellite provider might allow Ukraine to shut Starlink down and prevent the Russians from using it within its territory, doing so would likely do more harm to Ukraine's military effort than Russia's. There isn't really any other service comparable at this time. And when Amazon's Leo system comes on line it will face the same black market issues. I doubt it will have any more success than SpaceX in preventing Russia from obtaining its terminals.

Overall this issue is probably not a serious one militarily, however. Russia is not likely capable of obtaining enough black market terminals to make any significant difference on the battlefield. This story however highlights a positive aspect of these new constellations. Just as Russia can't be prevented from obtaining black market terminals, neither can the oppressed citizens in totalitarian nations like Russia and China be blocked as well. These constellations as designed act to defeat the censorship and information control of such nations, a very good thing.

A Soyuz launch at Baikonur damaged Russia's only launchpad capable of sending astronauts and crucial propellant to the ISS. "The rocket itself headed to space without incident, taking three astronauts -- Sergey Kud-Sverchkov and Sergei Mikaev of Russia and Chris Williams of NASA -- to the space station," reports the New York Times. "But the force of the rocket's exhaust shoved a service platform used for prelaunch preparations out of its protective shelter. The platform fell into the flame trench below." From the report: Photos and videos of the launch site the next day showed the platform out of place and mangled. "It's heavily damaged," said Anatoly Zak, who publishes RussianSpaceWeb.com, a close tracker of Russia's space activities, "and so probably it will have to be rebuilt. Maybe some of the hardware can be reused. But it fell down, and it's destroyed."

This is the latest embarrassment for the once-proud Russian space program, which the United States relied on from 2011 to 2020 to get NASA astronauts to orbit. The incident also raises questions about the future of the International Space Station if the launchpad cannot be quickly repaired. In a statement issued on Friday, Roscosmos, the state corporation in charge of the Russian space program, confirmed unspecified "damage" at the launchpad. "All necessary parts needed for repairs are at our disposal, and the damage will be dealt with in the near future," it said.

After a successful November 27th launch to the International Space Station, Russia discovered an accident had occurred on their launch site's mobile maintenance cabin — when a drone spotted it lying upside down in a flame trench. "The main issue with the structure collapse is that it puts Site 31/6 — the only Russian launch site capable of launching crew and cargo to the International Space Station (ISS) — out of service until the structure is fixed," reports the space-news site NASA Spaceflight There are other Soyuz 2 rocket launch pads, but they are either located at an unsuitable latitude, like Plesetsk, or not certified for crewed flights, like Vostochny, or decommissioned and transferred to a museum, like Gagarin's Start at Baikonur. As a result, Russia is temporarily unable to launch Soyuz crewed spacecraft and Progress cargo ships to the ISS, whose nearest launch (Progress MS-33) was scheduled for December 21....

When the rocket launched, a pressure difference was created between the space under the rocket, where gases from running engines are discharged, and the nook where the [144-ton] maintenance cabin was located. The resulting pressure difference pulled the service cabin out of the nook and threw it into the flame trench, where it fell upside down from a height of 20 m. Photos of the accident showed significant damage to the maintenance cabin, which, according to experts, is too extensive to allow for repairs. The only way to resume launches from Site 31/6 is to install a spare maintenance cabin or construct a new one.

Despite the fact that the fallen structure was manufactured in the 1960s, two similar service cabins were manufactured recently at the Tyazhmash heavy-engineering plant in Syzran for other Soyuz launch complexes at the Guiana Space Center and Vostochny Cosmodrome. The production of each cabin took around two years to complete, however, it was not for an emergency situation.
"Various experts gave different possible estimates of the recovery time of the Site 31 launch complex: from several months to three years."

An anonymous reader shared this report from The Conversation: To make interplanetary travel faster, safer, and more efficient, scientists need breakthroughs in propulsion technology. Artificial intelligence is one type of technology that has begun to provide some of these necessary breakthroughs. We're a team of engineers and graduate students who are studying how AI in general, and a subset of AI called machine learning in particular, can transform spacecraft propulsion. From optimizing nuclear thermal engines to managing complex plasma confinement in fusion systems, AI is reshaping propulsion design and operations. It is quickly becoming an indispensable partner in humankind's journey to the stars...

Early nuclear thermal propulsion designs from the 1960s, such as those in NASA's NERVA program, used solid uranium fuel molded into prism-shaped blocks. Since then, engineers have explored alternative configurations — from beds of ceramic pebbles to grooved rings with intricate channels... [T]he more efficiently a reactor can transfer heat from the fuel to the hydrogen, the more thrust it generates. This area is where reinforcement learning has proved to be essential. Optimizing the geometry and heat flow between fuel and propellant is a complex problem, involving countless variables — from the material properties to the amount of hydrogen that flows across the reactor at any given moment. Reinforcement learning can analyze these design variations and identify configurations that maximize heat transfer.

Psychology Today reports: In a study conducted in Milan, Italy, and published in November 2025, the sight of a person dressed as Batman led to a nearly doubled rate of people giving up their seat to a pregnant woman. Over the course of 138 subway rides, researchers found that people who saw "Batman" standing near the pregnant woman were far more altruistic than those who did not.

Researchers are calling this the "Batman effect," suggesting a form of "involuntary" mindfulness may be at play. Noticing these subtle social cues appears to shift people's typical, automatic reactions. Most interestingly, 44 percent of the people questioned reported they did not even consciously register Batman's presence... The superhero costume serves as a visual nudge, pulling us out of our default, self-focused mode and into a more generous, attentive state.
More from Futurism: Batman showing up is just one — albeit striking — way of promoting what's called "prosocial behavior," or the act of helping others around you, via introducing an unexpected event, the researchers write. "Our findings are similar to those of previous research linking present-moment awareness (mindfulness) to greater prosociality," said study lead author Francesco Pagnini, a professor of clinical psychology at the Università Cattolica in Milan, in a statement about the work. "This may create a context in which individuals become more attuned to social cues."

A new study published in Communications Earth & Environment has reconstructed the climate conditions of the ancient Indus River Valley civilization between 3000 and 1000 B.C., finding that four intense droughts -- each lasting more than 85 years -- likely drove the gradual decline of one of the world's earliest advanced societies.

The research team, led by Hiren Solanki at the Indian Institute of Technology, Gandhinagar, combined paleoclimate data from cave formations and lake records with computer models to determine that the region shifted from wetter-than-present monsoon conditions to prolonged dry spells as the tropical Pacific Ocean warmed. The third drought, peaking around 1733 B.C., proved the most severe: it lasted 164 years, reduced annual rainfall by 13%, and affected nearly the entire region.

Overall temperatures rose by 0.5 degrees Celsius and rainfall dropped between 10 and 20%. These changes shrank lakes and rivers, dried soils, and made agriculture increasingly difficult in areas away from major waterways. Harappan settlements progressively relocated eastward toward the Indus River over roughly 2,000 years. The civilization's long survival under repeated climate stress -- through crop switching, trade diversification, and settlement relocation -- offers lessons for modern communities facing environmental pressures, the researchers said.

Twenty years after surgeons in France performed the world's first face transplant, the experimental field that procedure launched is now confronting a troubling record of patient deaths, buried negative data and a healthcare system that leaves recipients financially devastated and medically vulnerable.

About 50 face transplants have been performed globally since Isabelle Dinoire received her partial face graft at University Hospital CHU Amiens-Picardie in November 2005. A 2024 JAMA Surgery study reported five-year graft survival of 85% and 10-year survival of 74%, concluding that the procedure is "an effective reconstructive option for patients with severe facial defects." The study did not track psychological wellbeing, financial outcomes, employment status or quality of life. Roughly 20% of face transplant patients have died from rejection, kidney failure, or heart failure.

The anti-rejection medications that keep transplanted faces alive can destroy kidneys and weaken immune systems to the point where routine infections become life-threatening. In the United States, the Department of Defense has funded most operations, treating them as a frontier for wounded veterans, because private insurers refuse to cover the costs. Patients who survive the surgery often find themselves unable to afford medications, transportation to follow-up appointments or basic caregiving. The field's long-term grants cover surgical innovation but not the lifelong needs of the people who receive these transplants.

An anonymous reader shares a report: NASA has slashed the number of astronaut missions on Boeing's Starliner contract and said the spacecraft's next mission to the International Space Station will fly without a crew, reducing the scope of a program hobbled by engineering woes and outpaced by SpaceX. The most recent mishap occurred during Starliner's first crewed test flight in 2024, carrying NASA astronauts Butch Wilmore and Suni Williams. Several thrusters on Starliner's propulsion system shut down during its approach to the ISS.

China's new JUNO neutrino observatory has delivered world-leading measurements after just 59 days, offering the most precise readings yet of two key neutrino oscillation parameters. "The physics result is already world-leading in the areas that it touches," says particle physicist Juan Pedro Ochoa-Ricoux of the University of California, Irvine, who co-leads a team on JUNO. "In particular, we measured two neutrino oscillation parameters, and that measurement is already for both parameters the best in the world." The results were published in two separate preprints on arXiv.org. Scientific American reports: JUNO's spherical detector, which is akin to a 13-story-tall fishbowl, primarily measures so-called electron antineutrinos spewing from the nearby Yangjian and Taishan nuclear plants. When the particles strike a proton inside the detector, a reaction triggers two light flashes that ping photomultiplier tubes and get converted into electrical signals. The new measurements from these neutrino-proton collisions are now considered the most precise for two oscillation parameters, which act as proxies for differences in their mass, according to Ochoa-Ricoux.

"It is the first time we've turned on a scientific instrument like JUNO that we've been working on for over a decade. It's just tremendously exciting," Ochoa-Ricoux says. "And then to see that we're able to already do world-leading measurements with it, even with such a small amount of data, that's also really exciting." Still, the physicists will need years' worth of neutrino detections to answer the mass-ordering conundrum.
