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.
