Retraction Watch reports: A trial date has been set in a $1 billion defamation case against Elsevier that alleges the company published what plaintiffs say was a manipulated study about an air purifying technology over objections from peer reviewers. The case has already cost Elsevier a $10,000 sanction from a judge.

Global Plasma Solutions (GPS), which makes air quality products, sued Elsevier in 2022 after the publisher declined to retract a 2021 paper in Building and Environment about GPS' needlepoint bipolar ionization technology, which it heavily marketed during the COVID-19 pandemic as an air purifier. The complaint claims Elsevier is responsible for the authors' alleged omission of data and misleading conclusions in the paper that fueled "massive" financial losses for the company, its lawyers claim. Elsevier knew the paper "failed peer review" under its "own standards," but moved forward with the article despite this knowledge, according to GPS, which now goes by GPS Air.

The complaint has survived a bid by Elsevier to dismiss the case, and a trial has been set for Dec. 7. In allowing the case to proceed, U.S. Magistrate Judge David Keesler said in a May 2024 opinion that GPS has "plausibly alleged actual malice" by Elsevier defined as "knowledge of falsity or reckless disregard for the truth." Chief Judge Martin Reidinger of the U.S. District Court for the Western District of North Carolina upheld Keesler's recommendation in July 2025...

Citing internal and discovery documents, GPS alleges an assessment of 19 journals revealed Elsevier has published more than 1,200 articles either without any peer review, or against the recommendations of the reviewers.

"AI went from being very terrible to seemingly genuinely quite good at a professional level in a very short space of time..." says the Verge's AI reporter. But AI systems "are still truly, truly terrible at some areas of math... even the days of the week." If you look at academic math papers, a lot of the time you won't see numbers... So they're still terrible, but they're now also very good at this other part. As to why, at some point you reach a critical mass of what these systems can do. We saw it with writing, we've seen it with programming. They're very good at forging connections between different areas, applying old methods in new ways, those kinds of things. It appears that the newer models they're training have apparently reached that level where it clicks, and now it can do math...

There are areas now where it seems to be producing work that is on par with good mathematicians, alongside other parts where yeah, it can't count. All caught up in that is whether it's going to rewrite employment structures or funding structures... One would hope [math researchers] would branch out into all of these new exciting areas or pose new questions. But AI won't do that, and that's the concern. And then that would leave the field quite sterile, and it will have all of these things that have been done, and maybe nothing left to pursue... [A] lot are scared that it's closing off the field. So by definition, those breakthroughs that lead to something surprising and new that you can say, "Oh, this works here," may not be happening anymore...

There were some bleak responses from graduate students I saw in essays posted online. Where's their place in this as future researchers? Do they have a place in this? Is it as glorified AI proof checkers? That will be quite an unsatisfying career, I imagine. Or maybe not, I don't know. We will see. I think anything used properly will be a net boon.
They also had an interesting response when asked if AI democratizes access to high-level mathematical proofs: A lot of the mathematicians I spoke to were almost quite weary of this, actually. They love the idea, in theory, of democratizing access. They're also quite fed up with AI-generated or -assisted papers that are flooding every publication imaginable, as well as the pre-print servers that they use in these fields. Some of those I spoke to said things like, "Oh, I got three emails this week alone with people being like, 'Hey, is this legit?'" Because they thought they'd solved something with ChatGPT or with Claude, and they also don't have the mathematical skills to check whether they've actually solved something.

On the flip side, there are parts where they said, "Well, we've got a talented undergrad who's done something that a talented undergrad would probably have never managed, and here they are doing grad-level work and they've produced a paper that is legit." And in the bigger scheme of things, a few I spoke to said, "Well yeah, a lot of these are in the ivory tower. Having access to this kind of thing globally could really boost access to the kind of things here." On the flip side, the cost. These things cost a lot to run.

Remember that rush rescue mission for NASA's $500M space telescope? It failed, reports CNN, and the LINK satellite won't be able to boost the telescope's orbit. NASA says its decades-old Swift telescope will now continue losing altitude, until it reaches Earth's atmosphere later this year and burns up.

CNN reports: Just weeks after LINK lifted off on July 3, it started to spin out of control. [Satellite designer] Katalyst was able to regain control of the satellite, but the company acknowledged that the issue cost it time, which would delay LINK's rendezvous with Swift by about a month. However, that postponement — at least initially — did not seem to be a deterrent to the mission. Now, NASA and Katalyst have announced that LINK's mission will not capture and boost Swift to a higher orbit "due to ongoing attitude control issues," according to statements Wednesday.

"NASA should be willing to move quickly and take smart risks when the potential return is worth it, and that is exactly what we did with this mission," NASA Administrator Jared Isaacman said in a statement. "This is not the outcome we were working toward, but it does not change why this mission was worth attempting. The team moved with extraordinary speed to give Swift a chance to carry out more science while advancing capabilities America will need for satellite servicing in the future...."

The mission team is forging ahead with its plan for LINK to rendezvous with Swift — but as a demonstration rather than a rescue. "We are going to learn everything we can from LINK's rendezvous attempt and put those lessons to work on the missions that follow," Isaacman said... Swift wasn't designed to be serviced in space, which means that insights from the demonstration could be used for future missions... "We have already learned a tremendous amount," [said Ghonhee Lee, CEO of Katalyst Space Technologies], "and now our job is to turn those lessons into something durable — building a repeatable playbook to inform future rendezvous and proximity operations and satellite servicing."

Long-time Slashdot reader AmiMoJo shared this report from the Guardian: Children's lungs grew bigger and stronger after the most polluting vehicles were restricted from entering London, a study has found. Examinations of London schoolchildren before and after the introduction of the city's ultra-low emission zone found a restoration of lung capacity that had been stunted by exposure to pollution... "Traffic pollution in cities damages children's health and development," said Chris Griffiths, a professor of primary care at the University of Oxford and Queen Mary University of London, and the study's joint senior author. "We provide the strongest evidence yet on how these harms can be prevented. Ambitious clean-air zones should be considered a priority for cities globally with traffic-related air pollution."

Air pollution from traffic has stunted the development of children's lungs in London for decades. Previous research found that by the age of eight or nine, children from the most polluted areas had 5-10% less lung capacity than their peers elsewhere. That impairment, which scientists said was the result of exposure to nitrogen dioxide, put them at increased risk as adults of developing respiratory diseases, such as asthma and chronic obstructive pulmonary disease, cardiovascular and metabolic disease, and premature death.

Reuters reports "a major success in a new field of cancer treatment this week, as Moderna and Merck announced a personalized mRNA cancer vaccine "reduced the risk of recurrence and spread of melanoma in a late-stage trial". The vaccine was tested with Merck's widely used immunotherapy drug Keytruda: Thousands of patients who have undergone surgery to remove high-risk melanoma tumors could benefit as soon as next year if regulators approve the vaccine, Moderna President Stephen Hoge said in an interview. This is the first positive late-stage trial result for an mRNA cancer vaccine, which trains a patient's immune system to fight tumors by targeting specific mutations in those cells, and the first such study to show that adding a treatment to Keytruda worked better than that therapy alone... Interim results of the ongoing study, released on Wednesday, found the treatment, Intismeran, met both its primary target of reducing cancer recurrence and its secondary goal of preventing tumors from spreading to other parts of the body, compared with Keytruda alone. When the vaccine is injected into a patient, the patient's cells produce copies of mutations for the immune system to recognize and destroy... Merck said the companies are already in talks with regulators about the treatment.
"Merck, Moderna and other companies are testing similar approaches against lung, breast and pancreatic cancers," the article points out. It adds that Karen Knudsen, CEO of the Parker Institute for Cancer Immunotherapy, "said the Moderna results could signal a new era for treating solid-tumor cancers."

More from CNN: The trial result is "a monumental leap forward," validating mRNA technology as a cancer treatment, said Dr. Julie Gralow, chief medical officer of the American Society of Clinical Oncology...

Roche and BioNTech, whose mRNA technology was used in the Pfizer COVID vaccines, are testing a similar treatment called autogene cevumeran in mid-stage studies in colon and pancreatic cancer patients who have undergone surgery. Results of the colon cancer trial are expected in 2027, with pancreatic trial results to follow in 2031. "We should be hearing results from multiple studies over the next few years and there's every reason to hope now, with this news, that many of them will be positive," said Dr. Robert Vonderheide, director of Penn Medicine's Abramson Cancer Center and president-elect of the American Association for Cancer Research.

China's Chang'e 7 mission is set to launch for the moon's south pole, where it will attempt the first-ever landing directly at the pole and search the region's dark craters for water ice. "It's an amazing mission," says Norbert Schorghofer, a Hawaii-based senior scientist at the Planetary Science Institute. "There has never been a landed mission to find water [on the moon]." If successful, China "will be the leader in lunar science," Schorghofer adds. Scientific American reports: Chang'e 7, China's seventh moon mission, is scheduled to launch on a Long March 5 rocket from the coastal Wenchang Space Launch Site on the island of Hainan, with the launch window opening on the morning of August 24 local time (the evening of August 23 EDT). The mission includes an orbiter, as well as a lander, which totes a rover and a novel "hopping" robot. The spacecraft will take up to six days to reach lunar orbit, where it will then spend two months preparing for a November landing meant to be a near bull's-eye on the lunar south pole. The mission also includes equipment from several international partners, highlighting China's growing global influence -- both on and off Earth.

The mission's lunar target is Shackleton Crater, a 21-kilometer-wide (13-mile-wide) pit with a rim that grazes the moon's south pole. No other spacecraft has ever landed so close. That proximity should allow Chang'e 7 to prospect for water ice trapped in smaller depressions near Shackleton that, because of the moon's tilt, never see sunlight and have temperatures just a few dozen degrees above absolute zero. "There are big reservoirs of ice water at the poles," says Simone Dell'Agnello, a physicist at Italy's National Institute for Nuclear Physics.

No one knows, however, just how big those reservoirs are or what their actual distribution is across the lunar south pole's crater-pocked desolation. And because that ice might be used as for manufacturing rocket fuel or to make potable water for thirsty astronauts, answering those questions is key for the U.S.'s and China's competing plans to construct crewed lunar outposts.

An anonymous reader quotes a report from The Guardian: A math professor at the University of California, Berkeley, criticizing a "severe" math deficiency among students in an op-ed for the San Francisco Standard, admitted to using artificial intelligence to help edit the piece. The Standard published a 2,000-word piece by Zvezdelina Stankova last week, in which the professor said some of her math students were "five to eight years" behind and lacked a "middle school" education on fractions and basic algebra. Stankova said the UC system's test-blind admissions were to blame, suggesting that students who weren't sufficiently prepared for the rigor of Berkeley's mathematics program were admitted because a longstanding benchmark like the SAT had disappeared.

Over the weekend, journalists at Berkeley's student newspaper, the Daily Californian, noticed the op-ed's language sounded like AI. According to Berkeley sophomore Francis Luo, they ran it through AI-detection software Pangram, which claimed 33% of the op-ed had been generated or assisted by AI. In response, Stankova admitted she had used AI software to "help edit the piece" but that the article was "the result of several hundred person-hours of intensive human work, of which about 80 hours are my own."

Stankova said by email she had used AI to locate "numerous documents and articles related to the initiative" but that "all analysis is the result of the team members." When asked about their AI usage policy, the Standard -- which published the op-ed -- shared this statement by email: "While AI may assist, our expectation is that humans are behind every article we publish and take responsibility for every word. Our understanding in working with the author of this op ed was -- and continues to be -- that this piece reflects her and her colleagues' extensive original analysis, research and expertise." Should the op-ed have been entirely written without artificial assistance or is the use of AI a distraction from the argument at hand? That's the question at the heart of the debate playing out online.

According to the op-ed, Stankova and her peers found that the number of students with a "severe deficit" in their readiness for a calculus I class had tripled after the University of California adopted test-blind admissions. Some students were allegedly five to eight years behind and struggling with basic algebra and fractions, among other concepts.

Much of that decline, Stankova argues, is from the removal of standardized tests like the SAT and ACT, which served as important benchmarks for identifying whether applicants were prepared for Berkeley-level coursework.

NASA has called off a $30 million mission to rescue its aging Swift space telescope after Katalyst Space's Link spacecraft developed persistent control and positioning problems. The Associated Press reports: Katalyst said Link will not attempt to capture Swift and boost it to a higher orbit because of problems with controlling the spacecraft. NASA said this means the telescope will plunge through the atmosphere after more than 20 years of tracking some of the biggest explosions in the universe like gamma ray bursts and exploding stars. Its demise is not expected before October.

NASA paid $30 million to Katalyst in an attempt to raise the telescope to a safer, longer-lasting orbit. Intense solar activity caused it to lose altitude faster than expected. The rescue spacecraft went into an uncontrollable spin a few weeks after its liftoff in early July. While flight controllers managed to slow Link's tumble, issues continued to plague its pointing and positioning in orbit.

"This is not the outcome we were working toward, but it does not change why this mission was worth attempting," NASA Administrator Jared Isaacman said in a statement. As a consolation prize, Katalyst will continue to operate Link in proximity with the telescope to demonstrate capabilities for future rescue operations. Katalyst CEO Ghonhee Lee said it was an ambitious mission on an aggressive timeline that was thrown together in under a year. "We took on this high-risk, high-reward challenge and are proud of the milestones we reached along the way," Lee said in a statement. "We have already learned a tremendous amount."

Moderna and Merck say their personalized mRNA melanoma vaccine significantly reduced both cancer recurrence and spread in a late-stage trial. The treatment could reach patients as soon as next year if regulators approve it. Reuters reports: Moderna developed the vaccine with Merck and tested it together with immunotherapy drug Keytruda, a widely used treatment for melanoma. [...] This is the first positive late-stage trial result for an mRNA cancer vaccine, which trains a patient's immune system to fight tumors by targeting specific mutations in those cells and the first such study to show that adding a treatment to Keytruda worked better than that therapy alone. Similar approaches are being tested against lung, breast and pancreatic cancers.

[...] The cancer treatment combines Merck's Keytruda with a made-to-order mRNA vaccine from Moderna that is based on an analysis of mutations found in the patients' own tumors. The trial enrolled 1,137 high-risk patients with stage IIB-IV melanoma that had been surgically removed. Volunteers were randomized to receive up to nine doses of Keytruda plus the personalized vaccine or Keytruda alone for about one year. The companies said no new safety signals have emerged in the trial. In January, the companies announced results of a mid-stage trial of the treatment showing that it reduced the risk of recurrence or death by 49% after five years. Karen Knudsen, CEO of the Parker Institute for Cancer Immunotherapy, said the Moderna results could signal a new era for treating solid-tumor cancers. "The positive hit here leads us into truly this next phase in immunotherapy," Knudsen said. "This is an auspicious start -- this is where things begin."

Moderna shares more than doubled on the news, adding about $30 billion to its market value.

A study of more than 64,000 people born around the end of Britain's postwar sugar rationing found that those exposed to less sugar during their first 1,000 days had lower rates of five cancers decades later, including roughly 69% lower liver cancer risk and 36% lower breast cancer risk. They also "showed signs of slower biological aging" and "continued to consume less sugar and had healthier diets overall," according to the authors of a new study published in The Conversation. From the report: After the second world war, sugar remained rationed in Britain for several years. But in September 1953, rationing ended and people started eating a lot more sugar. Consumption nearly doubled. This meant that children born just a few months apart had very different levels of sugar exposure both in the womb and during early childhood. For our study, we used data from over 64,000 people born in Britain between 1951 and 1956. Those born earlier spent a larger share of their first 1,000 days under sugar rationing, while those born later experienced progressively less of it.

[...] What is most surprising, however, is not the cancer results or the biological markers of ageing. It's how early-life sugar exposure continued to affect people's diets even 50 years later. We found that people who experienced sugar rationing early in life still consumed less sugar in adulthood, around age 50. They also ate less overall, and their diets were healthier and more diverse. This suggests that the level of sweetness people are exposed to very early in life may shape their taste preferences for a long time.

"We are in a 21st century space race," U.S. Senator Ted Cruz has said. And this week CNN noted a competition that for decades loomed in the background of geopolitics "is now roaring to the forefront," with China "demonstrating rapid advances in space technology" while the U.S. is "ratcheting up rhetoric about a looming battle for control of the cosmos." It's the fact that China plans to build a permanent settlement on the moon by 2040 that has prompted an urgent response from [U.S.] lawmakers... They've declared a new space race, and NASA is pledging to build a lunar outpost of America's own.... Both the United States and China plan to send robotic explorers to the south pole later this year, paving the way for human explorers to follow close behind.

The US is relying on the private sector to develop and build low-cost, exploratory robotic landers... Meanwhile, China is aiming to launch its robotic Chang'e-7 mission as soon as this month. The complex endeavor will seek to use four different robotic vehicles — an orbiter, lander, rover and mobile "hopper" — working in tandem to attempt to gather unprecedented data. The effort will include tools to drill for and directly analyze water ice, a feat that the US will only attempt with robotic missions slated for next year at the earliest. "If lunar water ice is successfully located, it could significantly reduce the cost and time required to transport water from Earth, facilitating the establishment of a human base for long-term activities on the moon and enabling further exploration of Mars or deep space," Tang Yuhua, the deputy chief designer of the Chang'e-7 mission, said in a 2025 interview with state media.

The oncoming flurry of south-pole-centric activity, with few established international laws to govern the outcomes, is heightening the drama of this rivalry... But with a much more ambitious goal — a future in which people attempt to flourish within permanent settlements rather than just visit the moon — the stakes of this new space race are even higher, according to Clayton Swope, the deputy director of the Aerospace Security Project at the Center for Strategic and International Studies, a bipartisan nonprofit. "The long-term vision will take generations to execute on," Swope said. "But in my mind, it's a scenario where there are people being born, people dying, their families, children growing up in a place that is not Earth — so that looks a lot like a city, more than it looks like an expedition to the south pole." If such a future comes to fruition, Swope added, his hope is that such extraterrestrial colonies would be governed by rules reminiscent of Western ideals and democratic principles. Whether China would be on the same page is an open question.
China is already fine-tuning its plans for a lunar settlement, CNN writes: The country envisions the International Lunar Research Station, or ILRS, as a sprawling science-focused facility on the moon's surface that can be operated robotically, "with the prospect of subsequent human presence," according to a government's ILRS website. China could partner with Russia to build a massive nuclear reactor to power the base, though questions remain regarding how the war in Ukraine may impact Russia's ability to deliver... China and Russia were mapping these plans long before the US announced its own intention to build a nuclear reactor on the moon last year and detailed its plans for a lunar settlement spanning hundreds of square miles... Who will write the rules? And how, exactly, will the use of lunar resources be policed on the international stage?
Meanwhile, NASA "still does not have a vehicle capable of getting astronauts down to the lunar surface," the article points out: Returning to the moon is not as simple as repeating Apollo. The space agency cannot — and does not wish to — replicate its 20th century lunar-landing success. The supply chains, skilled machinists and factories that built Apollo's rockets, landers and command modules no longer exist. And while the Apollo landings stuck close to the lunar equator, landing near the south pole is substantially more complex and requires more powerful vehicles.... China, meanwhile, has been laser focused on its lunar exploration program since 2004, using its top-down, central planning system to keep resources flowing toward specific goals.

An anonymous reader shares this report from Space.com: On Saturday evening (Aug. 15), SpaceX set another mark, for the shortest time between orbital flights: It launched two Falcon 9 rockets just 38 minutes apart, besting its old mark — set on Aug. 31, 2024 with two Starlink missions — by 27 minutes.

The first liftoff, from Florida's Cape Canaveral Space Force Station, occurred Saturday at 9:12 p.m. EDT (0112 GMT on Aug. 16) and carried eight satellites to low Earth orbit (LEO) for Louisiana-based telecom company Globalstar. All eight spacecraft were deployed successfully, separating over a six-minute span beginning 56.5 minutes after liftoff, SpaceX announced via social media. While that Falcon 9 was powering its way to low Earth orbit, another one launched from Vandenberg Space Force Base, on California's central coast. That liftoff, at 9:50 p.m. EDT (6:50 p.m. local time; 0150 GMT on Aug. 16), kicked off a mission for the U.S. Space Force called USSF-366...

Both of Saturday's missions featured successful rocket landings. The Falcon 9 first stage that launched the Globalstar mission came back for a touchdown at Cape Canaveral about eight minutes after launch. It was the 14th flight for that particular booster. The USSF-366 Falcon 9 first stage, meanwhile, came back to Earth about 8.5 minutes after its launch, touching down in the Pacific Ocean on the SpaceX droneship "Of Course I Still Love You." That booster now has 18 missions under its belt.

Saturday's doubleheader brought the tally of Falcon 9 launches in 2026 to 96. The vast majority of those — about 75% — have been Starlink missions.

Phys.org reports: Future fusion power plants aim to recreate the heart of a star here on Earth to power our future energy needs. While the core fusion plasma will burn at hundreds of millions of degrees, the surrounding structural components must handle sudden, punishing heat loads that rival the extreme temperatures faced by spacecraft upon reentry into Earth's atmosphere. Copper and its alloys are primary candidates for handling these intense heat fluctuations, making it vital to understand exactly how the metal behaves when pushed to its melting point.

Now, researchers at the Department of Energy's SLAC National Accelerator Laboratory and collaborators have captured a detailed, step-by-step look at copper atoms as they underwent extreme heating. Published in Nature Communications, the results revealed a key parameter that allowed copper's crystal lattice to melt steadily rather than collapse instantaneously, as earlier simulations predicted. "These results greatly improve the simulations we use to predict which materials have the best shot at surviving the extreme conditions of future fusion reaction chambers," said Mianzhen Mo, a SLAC staff scientist who led the research. "They also demonstrate the incredible, atomic-scale resolution imaging we can achieve at SLAC's electron camera...."

Researchers use computer simulations, aided by AI and machine learning, to sift through innumerable combinations of elements and identify promising candidate materials for real-world testing.
"Whether the copper melts slowly or suddenly collapses, by the time the researchers look, the sample resembles nothing more than a metallic brown puddle," the article points out. But SLAC's powerful electron camera captures atomic and molecular movements down to the femtosecond — a millionth of a billionth of a second — and revealed that at around 1,424 degreesC (2,595 degreesF) there was still gradual melting as the temperature rose beyond the superheating limit, with real-world conditions showing the atoms shifted and retained some order.

"It's a straightforward solution," said Mianzhen Mo, a SLAC staff scientist who led the research. "But molecular dynamics simulations had been overlooking it for years. When you have complex simulations attempting to capture every aspect of reality, down to individual atoms, it takes real-world data to show you what's missing from the calculations."

Astronomers using the James Webb Space Telescope say they may have found a new class of object: a "black hole star," in which a black hole is wrapped in dense gas and radiates in ways that resemble an enormous star. The Guardian reports: The international team made the breakthrough after focusing their attention on a mysterious red spot in images of the early universe captured by Nasa's James Webb space telescope. The object was lurking in the constellation of Cetus, the Whale, billions of light years from Earth. It is thought to have formed 660m years after the big bang, astronomers' leading theory as to how the universe began. Measurements of the exotic body found that while it resembles an immense star, it releases 100bn times more energy than any known star can produce. The energy output is far closer to that observed from black holes than stars. The findings have been published in the journal Nature.

Astronomers using JWST have found three actively feeding supermassive black holes in the distant galaxy J0148-4214, seen as it existed about 1.2 billion years after the Big Bang. Two sit just 620 light-years apart near the galaxy's center and are expected to merge within a few hundred million years. Phys.org reports: Theories of galaxy evolution -- based on observations -- suggest that, early in the history of the universe, galaxies came very close to one another and merged. In the process, black holes at their centers also merged, giving rise to even more massive black holes at the centers of the merged galaxies. The analysis yields black hole masses of approximately 80 million, 0.6 million and 2 million solar masses. The most massive black hole is accreting at a lower rate than the nearby black hole with a mass of 0.6 million solar masses, which is actively feeding and even exceeding the maximum accretion rate predicted by basic theories of black hole growth (the Eddington limit).

"The JWST data allowed us not only to identify the three black holes, but also to estimate their masses, accretion rates and the stellar mass of the galaxy," says Dr. Giovanni Mazzolari, second author of the study and researcher at MPE. "We find a total stellar mass of about 1.3 billion solar masses, and the black holes represent a significant fraction of that."

The central black hole pair is expected to merge within the next few hundred million years. "These results are extremely exciting," adds Roberto Maiolino, professor at the University of Cambridge and co-author of the study. "They suggest that black hole merging may be an additional, fast route for their rapid growth in the early universe." The third black hole, located off-nucleus, may be the remnant of a previous merger, be displaced from the center by a gravitational recoil kick, or be currently migrating inward. The findings have been published in the journal Astronomy & Astrophysics.
