Long-time Slashdot reader schwit1 shared this report from the blog Interesting Engineering: A team of students made history this month by performing Europe's first rocket hop test.

Those who have followed SpaceX's trajectory will know hop tests are a vital stepping stone for a reusable rocket program, as they allow engineers to test their rocket's landing capabilities.

Impressively, no private company or space agency in Europe had ever performed a rocket hop test before. Essentially, a group of students performed one of the most important rocket tests in the history of European rocketry.

However, the remarkable nature of this story doesn't end there. Amazingly, the whole thing was almost derailed by a piece of cheese. A slice of Gruyère the team strapped to their rocket's landing legs almost caused the rocket to spin out of control.

Thankfully, disaster was averted, and the historic hopper didn't end up as rocket de-Brie.

Slashdot reader samleecole shared this report from 404 Media: Northwell Health, New York State's largest healthcare provider, recently launched a large language model tool that it is encouraging doctors and clinicians to use for translation, sensitive patient data, and has suggested it can be used for diagnostic purposes, 404 Media has learned. Northwell Health has more than 85,000 employees.

An internal presentation and employee chats obtained by 404 Media shows how healthcare professionals are using LLMs and chatbots to edit writing, make hiring decisions, do administrative tasks, and handle patient data. In the presentation given in August, Rebecca Kaul, senior vice president and chief of digital innovation and transformation at Northwell, along with a senior engineer, discussed the launch of the tool, called AI Hub, and gave a demonstration of how clinicians and researchers—or anyone with a Northwell email address—can use it... AI Hub can be used for "clinical or clinical adjacent" tasks, as well as answering questions about hospital policies and billing, writing job descriptions and editing writing, and summarizing electronic medical record excerpts and inputting patients' personally identifying and protected health information.

The demonstration also showed potential capabilities that included "detect pancreas cancer," and "parse HL7," a health data standard used to share electronic health records.

The leaked presentation shows that hospitals are increasingly using AI and LLMs to streamlining administrative tasks, and shows that some are experimenting with or at least considering how LLMs would be used in clinical settings or in interactions with patients.

Somewhere off in interstellar space, 15.4 billion miles away from Earth, NASA's 47-year-old Voyager "recently went quiet," reports Mashable.

The probe "shut off its main radio transmitter for communicating with mission control..." Voyager's problem began on October 16, when flight controllers sent the robotic explorer a somewhat routine command to turn on a heater. Two days later, when NASA expected to receive a response from the spacecraft, the team learned something tripped Voyager's fault protection system, which turned off its X-band transmitter. By October 19, communication had altogether stopped.

The flight team was not optimistic. However, Voyager 1 was equipped with a backup that relies on a different, albeit significantly fainter, frequency. No one knew if the second radio transmitter could still work, given the aging spacecraft's extreme distance.

Days later, engineers with the Deep Space Network, a system of three enormous radio dish arrays on Earth, found the signal whispering back over the S-band transmitter. The device hadn't been used since 1981, according to NASA.

"The team is now working to gather information that will help them figure out what happened and return Voyager 1 to normal operations," NASA said in a recent mission update.
It's been more than 12 years since Voyager entered interstellar space, the article points out. And interstellar space "is a high-radiation environment that nothing human-made has ever flown in before.

"That means the only thing the teams running the old probes can count on are surprises."

Long-time Slashdot reader yet-another-lobbyist writes: Phys.org has an article on the recent discovery of super stretchy nanofibers in natural spider silk! The thinnest natural spider silk nanofibrils ever seen are only a few molecular layers thin, about 5 nm. They are too thin to be seen even with a very powerful optical microscope. Researchers used atomic force microscopy (AFM) not only to visualize them, but also to probe their stretchiness and strength.

Even the original article is available without a paywall. Mechanical tests of molecularly thin materials — pretty cool!
The doctoral candidate's advisor thought it would be impossible to perform the measurements, according to the article, which quotes him as saying "It's actually kind of crazy to think that it's even possible.... We humans think we're so great and we can invent things, but if you just take a step outside, you find so many things that are more exciting."

That advisor — long term spider-silk researcher of Hannes Schniepp (also a co-author on the paper) — adds that the tip of the needle was so sharp, its end was only a few atoms thick. "You would not see the end of it in the best optical microscope. It will just disappear because it's so small that you can't even see it. It's probably one of the highest developed technologies on the planet." If humans find a way to replicate the structure of spider silk, it could be manufactured for use in practical applications. "You could make a super bungee cord from it," said Schniepp. "Or a shield around a structure where you have something incoming at high velocity and you need to absorb a lot of energy. Things like that."

An anonymous reader quotes a report from The Guardian: More than 50 US lawmakers are calling on the Environmental Protection Agency (EPA) to join dozens of other countries in banning a widely used weedkiller linked to Parkinson's disease and other health dangers. In a October 31 letter (PDF) to the agency, seven US senators said that paraquat, a weedkiller commonly applied on US farms, was a "highly toxic pesticide whose continued use cannot be justified given its harms to farmworkers and rural communities". The call for a ban from the senators came after 47 members of the US House of Representatives sent a similar letter (PDF) to the EPA calling for a ban earlier in October.

The lawmakers cite scientific links between paraquat use and development of Parkinson's and other "life threatening diseases" as well as "grave impacts on the environment". "Health risks include a higher risk of Parkinson's disease, with some studies finding a 64% increase in the likelihood of developing Parkinson's, non-Hodgkin's Lymphoma, thyroid cancer, and other thyroid issues," they wrote. The New Jersey senator Cory Booker, organizer of the Senate letter, said the risks of paraquat exposure were "well documented" and that it was "irresponsible" for the EPA to continue to allow its use. "I hope the EPA will follow the science and ban paraquat," Booker said. The EPA has long maintained that there is no "clear link" between paraquat exposure and Parkinson's disease, though the agency does have a number of restrictions on use of the chemical due to its acute toxicity. The agency issued a draft report earlier this year affirming its position. Still, the agency said at that time that it would be reviewing more scientific studies and would issue a final report by January 17, 2025.

An anonymous reader quotes a report from The Guardian: A new global inventory has catalogued air pollution from space activities from 2020 to 2022. The inventory includes time, position and pollution from 446 launchers as they ascended and the tracks of re-entries as objects are heated to extreme temperatures and break up or burn up in the upper atmosphere. It catalogues the pollution from 63,000 tons of rocket propellants used in 2022 and from 3,622 objects, including rocket parts and satellites, that re-entered the atmosphere between 2020 and 2023, amounting to about 12,000 tons. [...]

Types of launch pollutants depend on the propellent but can include particles of soot and aluminum oxides as well as nitrogen oxides, chlorine and water vapour and carbon dioxide. Extreme heat on re-entry causes atmospheric oxygen and nitrogen to combine to form more nitrogen oxides and also produces tiny metal-oxide particles as the objects break and burn up. Soot emitted high in the atmosphere can persist for several years, with a resulting climate warming impact that is up to 500 times greater than the same amount of soot from aviation or ground-level sources. Aluminum oxide particles, nitrogen oxides and chloride can consume the ozone in the stratosphere that protects us from the sun's ultraviolet radiation. These can remain in the atmosphere for decades. Dr Connor Barker, of the UCL team, said: "Many rocket manufacturers and space agencies keep this information tightly controlled. We had to be creative about the different sources we consulted, from launch live streams on YouTube to online databases maintained by space enthusiasts in their spare time."

Australian mathematicians have proven the famous "infinite monkey theorem" impossible within the universe's lifespan. The theorem suggests monkeys typing randomly would eventually produce Shakespeare's complete works. Scientists Stephen Woodcock and Jay Falletta calculated that even 200,000 chimpanzees typing one character per second until the universe's heat death would fail to reproduce Shakespeare's writings.

A single chimp has only a 5% chance of typing "bananas" in its lifetime, with more complex phrases facing astronomically lower odds. "This finding places the theorem among other probability puzzles and paradoxes... where using the idea of infinite resources gives results that don't match up with what we get when we consider the constraints of our universe," Associate Prof Woodcock was quoted as saying by BBC.

A new study suggests Uranus' moon Miranda may harbor a vast subsurface ocean, challenging previous assumptions about its frozen state and positioning it as a potential ocean world alongside other icy moons. Phys.Org reports: Among the moons in the solar system, Miranda stands out. The few images Voyager 2 captured in 1986 show Miranda's southern hemisphere (the only part we've seen) is a Frankenstein-like hodgepodge of grooved terrain quartered off by rough scarps and cratered areas, like squares on a quilt. Most researchers suspect these bizarre structures are the result of tidal forces and heating within the moon. Caleb Strom, a graduate student at the University of North Dakota who worked with Nordheim and Alex Patthoff of the Planetary Science Institute in Arizona, revisited the Voyager 2 images. The team set out to explain Miranda's enigmatic geology by reverse engineering the surface features, working backward to uncover what the moon's interior structure must have been to shape the moon's geology in response to tidal forcing.

After first mapping the various surface features like cracks, ridges and Miranda's unique trapezoidal coronae, the team developed a computer model to test several possible structures of the moon's interior, matching the predicted stress patterns to the actual surface geology. The setup that produced the best match between predicted stress patterns and observed surface features required the existence of vast ocean beneath Miranda's icy surface some 100-500 million years ago. This subsurface ocean was at least 62 miles (100 kilometers) deep, according to the study, and hidden beneath an icy crust no more than 19 miles (30 kilometers) thick. Given Miranda has a radius of just 146 miles (235 kilometers), the ocean would have filled almost half of the moon's body. "That result was a big surprise to the team," Strom said.

Key to creating that ocean, the researchers believe, were tidal forces between Miranda and nearby moons. These regular gravitational tugs can be amplified by orbital resonances -- a configuration where each moon's period around a planet is an exact integer of the others' periods. Jupiter's moons Io and Europa, for example, have a 2:1 resonance: For every two orbits Io makes around Jupiter, Europa makes exactly one, leading to tidal forces that are known to sustain an ocean beneath Europa's surface. These orbital configurations and the resulting tidal forces deform the moons like rubber balls, leading to friction and heat that keeps interiors warm. This also creates stresses that crack the surface, creating a rich tapestry of geologic features. Numerical simulations have suggested that Miranda and its neighboring moons likely had such a resonance in the past, offering a potential mechanism that could have warmed Miranda's interior to produce and maintain a subsurface ocean.

At some point, the moons' orbital ballet desynchronized, slowing the heating process so that the moon's insides started to cool and solidify. But the team doesn't think Miranda's interior has fully frozen yet. If the ocean had completely frozen, Nordheim explained, it would have expanded and caused certain telltale cracks on the surface, which aren't there. This suggests that Miranda is still cooling -- and may have an ocean beneath its surface even now. Miranda's modern-day ocean is probably relatively thin, Strom noted. "But the suggestion of an ocean inside one of the most distant moons in the solar system is remarkable," he said. Miranda wasn't predicted to have an ocean. With its small size and old age, scientists thought it would likely be a frozen ball of ice. Any leftover heat from its formation was assumed to have dissipated long ago. But as Patthoff pointed out, predictions about ice moons can be wrong, as evidenced by Saturn's moon Enceladus. The study has been published in The Planetary Science Journal.

A new study examining a large sample of privately insured patients with obesity found that use of drugs such as Ozempic and Wegovy as anti-obesity medications more than doubled from 2022 to 2023. During that same period, there was a 25.6% decrease in patients undergoing metabolic bariatric surgery to treat obesity. From a report: The study, by researchers at Brigham and Women's Hospital, in collaboration with researchers at Harvard T.H. Chan School of Public Health and the Brown School of Public Health, is published in JAMA Network Open. "Our study provides one of the first national estimates of the decline in utilization of bariatric metabolic surgery among privately insured patients corresponding to the rising use of blockbuster GLP-1 RA drugs," said senior author Thomas C. Tsai, a metabolic bariatric surgeon at Brigham and Women's Hospital.

Using a national sample of medical insurance claims data from more than 17 million privately insured adults, the researchers identified patients with a diagnosis of obesity without diabetes in 2022-2023. The study found a sharp increase in the share of patients who received glucagon-like peptide-1 receptor agonists, or GLP-1 RAs, during the study period, with GLP-1 RA use increasing 132.6% from the last six months of 2022 to the last six months of 2023 (from 1.89 to 4.41 patients per 1,000 patients).

Meanwhile, there was a 25.6% decrease in use of bariatric metabolic surgery during the same period (from 0.22 to 0.16 patients per 1,000 patients). Among the sample of patients with obesity, 94.7% received neither form of treatment during the study period (while 5% received GLP-1 RAs and 0.3% received surgery). Compared to patients who were prescribed GLP-1 RAs, patients who underwent surgery tended to be more medically complex.

An anonymous reader quotes a report from the European Space Agency: White dots arranged in five clusters against a black background (PNG). This is the simulated extraterrestrial signal transmitted from Mars and deciphered by a father and a daughter on Earth after a year-long decoding effort. On June 7, 2024, media artist Daniela de Paulis received this simple, retro-looking image depicting five amino acids in her inbox. It was the solution to a cosmic puzzle beamed from ESA's ExoMars Trace Gas Orbiter (TGO) in May 2023, when the European spacecraft played alien as part of the multidisciplinary art project 'A Sign in Space.' After three radio astronomy observatories on Earth intercepted the signal, the challenge was first to extract the message from the raw data of the radio signal, and secondly to decode it. In just 10 days, a community of 5000 citizen scientists gathered online and managed to extract the signal. The second task took longer and required some visionary minds.

US citizens Ken and Keli Chaffin cracked the code following their intuition and running simulations for hours and days on end. The father and daughter team discovered that the message contained movement, suggesting some sort of cellular formation and life forms. Amino acids and proteins are the building blocks of life. Now that the cryptic signal has been deciphered, the quest for meaning begins. The interpretation of the message, like any art piece, remains open. Daniela crafted the message with a small group of astronomers and computer scientists, with support from ESA, the SETI Institute and the Green Bank Observatory. The artist and collaborators behind the project are now taking a step back and witnessing how citizen scientists are shaping the challenge on their own.

Longtime Slashdot reader AmiMoJo shares a report from the Associated Press: Tech behemoth OpenAI has touted its artificial intelligence-powered transcription tool Whisper as having near "human level robustness and accuracy." But Whisper has a major flaw: It is prone to making up chunks of text or even entire sentences, according to interviews with more than a dozen software engineers, developers and academic researchers. Those experts said some of the invented text -- known in the industry as hallucinations -- can include racial commentary, violent rhetoric and even imagined medical treatments. Experts said that such fabrications are problematic because Whisper is being used in a slew of industries worldwide to translate and transcribe interviews, generate text in popular consumer technologies and create subtitles for videos.

The full extent of the problem is difficult to discern, but researchers and engineers said they frequently have come across Whisper's hallucinations in their work. A University of Michigan researcher conducting a study of public meetings, for example, said he found hallucinations in eight out of every 10 audio transcriptions he inspected, before he started trying to improve the model. A machine learning engineer said he initially discovered hallucinations in about half of the over 100 hours of Whisper transcriptions he analyzed. A third developer said he found hallucinations in nearly every one of the 26,000 transcripts he created with Whisper. The problems persist even in well-recorded, short audio samples. A recent study by computer scientists uncovered 187 hallucinations in more than 13,000 clear audio snippets they examined. That trend would lead to tens of thousands of faulty transcriptions over millions of recordings, researchers said.

NASA's economic impact report highlights that in fiscal year 2023, the agency's initiatives contributed $75.6 billion to the U.S. economy, created over 300,000 jobs, and drove advancements in areas like space exploration, climate research, and technology innovation. The agency's budget for that year was $25.4 billion. Space.com reports: The Moon to Mars program alone created $23.8 billion in economic output and 96,479 jobs, while investments in climate research and technology contributed $7.9 billion and 32,900 jobs. The report also drills down into impacts in each state, with 45 states seeing over $10 million in impact and eight states surpassing the $1 billion mark. [...]

NASA's missions supported 304,803 jobs across America, according to the report -- the third agency-wide study of its kind -- generating an estimated total of $9.5 billion in federal, state, and local taxes. Additionally, NASA's technological innovations and transfers in 2023 led to 40 new patent applications, 69 patents issued, and thousands of software usage agreements. A number of NASA technology spinoffs have become everyday household items. The full NASA economic impact report can be found here.

Ars Technica's Stephen Clark reports: For those who follow NASA's human spaceflight program, a burning question for the last year-and-a-half has been what caused the Orion spacecraft's heat shield to crack and chip away during atmospheric reentry on the unpiloted Artemis I test flight in late 2022. Multiple NASA officials said Monday they now know the answer, but they're not telling. Instead, agency officials want to wait until more reviews are done to determine what this means for Artemis II, the Orion spacecraft's first crew mission around the Moon, officially scheduled for launch in September 2025.

"We have gotten to a root cause," said Lakiesha Hawkins, assistant deputy associate administrator for NASA's Moon to Mars program office, in response to a question from Ars on Monday at the Wernher von Braun Space Exploration Symposium. "We are having conversations within the agency to make sure that we have a good understanding of not only what's going on with the heat shield, but also next steps and how that actually applies to the course that we take for Artemis II," she said. "And we'll be in a position to be able to share where we are with that hopefully before the end of the year."

While the space program is far down the list of most voters' priorities, this means a decision and announcement on what will happen with Artemis II won't come until the post-election lame duck period in the waning weeks of the Biden administration, and likely Bill Nelson's tenure as NASA administrator. This is several months later than NASA officials expected to make a decision. The question here is whether NASA managers decide it is safe enough to fly the Orion heat shield as-is on Artemis II, or if it is too risky with people onboard. Artemis II will be a 10-day mission taking its four-person crew on a path around the far side of the Moon, then back to Earth. This will be the first time people travel to such distances since the Apollo program ended more than 50 years ago.

When SpaceX developed reusable boosters for its Falcon rockets, it helped cut costs of launches.

Now the Wall Street Journal reports that last week's first-time catch of "its huge Starship booster" could "extend SpaceX's cost advantages, especially in launches to low-Earth orbit, where SpaceX and others operate satellites." A fully and rapidly reusable Starship would push down SpaceX's costs by limiting the need to crank out new hardware and cutting downtime between flights, space industry executives say. Bain, the consulting firm, has estimated that Starship would reduce the cost of getting each kilogram to low-Earth orbit by 50 to 80 times... SpaceX's rocket peers are moving toward reusability, but they are behind the progress Musk's company has made.

- The huge booster that will power New Glenn, the orbital rocket Jeff Bezos' Blue Origin is developing, is designed to be reusable. That rocket is slated to launch for the first time next month.

- ULA, the rocket operator owned by Boeing and Lockheed Martin, is looking to recover the two engines that help power the first part of its new rocket, Vulcan Centaur. The parent company for Arianespace, whose new vehicle is powered by an expendable booster, has also invested in a startup developing a reusable booster.

- Last year, Rocket Lab USA used an engine that had flown before on a flight of its Electron rocket, and is working on a new vehicle, called Neutron, with a booster it could use again.

- Jason Kim, chief executive of Firefly Aerospace, said the reusable vehicle the Texas-based company is developing with Northrop Grumman would give launch customers more flexibility and better pricing. "It really comes down to the affordability and the schedule," Kim said in a recent interview.
"We need reusability for rockets, just like we have reusability for cars, for airplanes, for bicycles, for horses," Musk said in a video SpaceX posted earlier this year...

Communications of the ACM checks in on the quest for room-temperature superconductivity. "Time and time again, physicists have announced breakthroughs that were later found to be irreproducible, in error, or even fraudulent."

But "The issue is once again simmering..." In January 2024, a group of researchers from Europe and South America announced they had achieved a milestone in room-temperature ambient-pressure superconductivity. Using Scotch-taped cleaved pyrolytic graphite with surface wrinkles, which formed line defects, they observed a room-temperature superconducting state. Their paper, published in the journal Advanced Quantum Technologies, has gained considerable attention in the scientific world... Although many in the scientific community remain incredulous, if valid, this development could help solve a key piece of the puzzle: how defects and wrinkles in a material such as scotch-taped cleaved pyrolytic graphite (HOPG) affect electrical properties and behavior within superconductive systems...

"We haven't reached a point where there is a clear path to room temperature superconductivity because researchers are either overly enthusiastic or deceptive," said Elie Track, chief technology officer at HYPRES, Inc., an Elmsford, NY, company that develops and commercializes superconductor integrated circuits (ICs) and systems. "People fail to check measurements and others can't reproduce their results. There is a lot of carelessness and sloppy science surrounding the space because people are so eager to achieve success." The team conducting research into scotch-taped cleaved pyrolytic graphite believe their discovery could tilt the search for practically useful room-temperature superconductivity in a favorable direction. They reported they were able to achieve one-dimensional superconductivity in pyrolytic graphite at temperatures as great as 300 degrees Kelvin (26.85 degrees Celsius), and at ambient pressure. Vinokur and physicist Maria Cristina Diamantini described the development as the first "unambiguous experimental evidence" for a global room temperature zero-resistance state. If true, the team's research could illuminate a path to new superconducting materials....

Others remain skeptical, however. For example Alan Kadin [a technical consultant in the field and a former professor of electrical engineering at the University of Rochester] pointed out that one of the key researchers for the project, Yakov Kopelevich, has been working in the field for two decades and, so far, "The results are not reproducible in other labs...Until someone else independently reproduces these results, I think we can safely ignore them," he argued...

Yet as scientists continue to bang away at the superconducting challenge — including the possibility of using generative AI to explore materials and techniques — optimism is growing that a major breakthrough could occur.

SpaceNews reports: SpaceX's Super Heavy booster came within a second of aborting a "catch" landing attempt on the latest Starship test flight, according to audio posted online, apparently inadvertently, by Elon Musk... In the audio, one person, not identified, described an issue with the Super Heavy landing burn where a "misconfigured" parameter meant that spin pressure, presuming in the Raptor engines in the booster, did not increase as expected. "We were one second away from that tripping and telling the rocket to abort and try to crash into the ground next to the tower," that person said. That scenario would "erroneously tell a healthy rocket to not try that catch...."

The people on the audio note that there had been discussions of delaying the Flight 5 launch to provide additional time to check those parameters. "We were scared about the fact that we had 100 aborts that were not super-trivial," one person said... Another issue discussed in the audio... was a cover on a chine, a vertical structure on the booster, that came off as the vehicle went transonic during its descent. A SpaceX official said in the audio that having chine cover come off was something that they were worried about before launch... The person also started to discuss an issue with the engine plume during the landing burn, but the video stops at that point.

The discussions appeared to involve planning for the next Starship test flight, Flight 6. SpaceX is moving ahead with preparations for the flight, moving the next Super Heavy booster to the launch site for testing. "Flight 6 is coming up soon!" Musk posted early Oct. 25.

"We passed Berkeley air — just outdoor air — into the material to see how it would perform," says U.C. Berkeley chemistry professor Omar Yaghi, "and it was beautiful.

"It cleaned the air entirely of CO2," Yaghi says in an announcement from the university. "Everything."

SFGate calls it "a discovery that could help potentially mitigate the effects of climate change..." Yaghi's lab has worked on carbon capture since the 1990s and began work on these crystalline structures in 2005. The innovative substance has lots of tiny holes, making it "great for storing gases or liquids, much like a sponge holds water," Yaghi said... While it could take one to two years for the powder to be usable in large-scale applications, Yaghi co-founded Atoco, an Irvine company, to commercialize his research and expand it beyond just carbon capture and storage.
"Capturing carbon from the air just got easier," says the headline on the anouncement from the university, which explains why this technology is crucial: [T]oday's carbon capture technologies work well only for concentrated sources of carbon, such as power plant exhaust. The same methods cannot efficiently capture carbon dioxide from ambient air, where concentrations are hundreds of times lower than in flue gases. Yet direct air capture, or DAC, is being counted on to reverse the rise of CO2 levels, which have reached 426 parts per million, 50% higher than levels before the Industrial Revolution. Without it, according to the Intergovernmental Panel on Climate Change, we won't reach humanity's goal of limiting warming to 1.5 degreesC (2.7 degreesF) above preexisting global averages.

A new type of absorbing material developed by chemists at the University of California, Berkeley, could help get the world to negative emissions... According to Yaghi, the new material could be substituted easily into carbon capture systems already deployed or being piloted to remove CO2 from refinery emissions and capture atmospheric CO2 for storage underground. UC Berkeley graduate student Zihui Zhou, the paper's first author, said that a mere 200 grams of the material, a bit less than half a pound, can take up as much CO2 in a year — 20 kilograms (44 pounds) — as a tree.
Their research was published this week in the journal Nature.

And it's also interesting that they're using AI, according to the university's announcement: Yaghi is optimistic that artificial intelligence can help speed up the design of even better COFs and MOFs for carbon capture or other purposes, specifically by identifying the chemical conditions required to synthesize their crystalline structures. He is scientific director of a research center at UC Berkeley, the Bakar Institute of Digital Materials for the Planet (BIDMaP), which employs AI to develop cost-efficient, easily deployable versions of MOFs and COFs to help limit and address the impacts of climate change. "We're very, very excited about blending AI with the chemistry that we've been doing," he said.
Another potential use could be for harvesting water from desert air for drinking water, Yaghi told SFGate. But he seems very focused specifically on carbon capture.

"Another thing is that we need a strong determination among officials and industries to make carbon capture a high priority. Things have to change, but I believe that direct carbon capture from air is very doable."

"After safely splashing down on Earth as part of NASA's SpaceX Crew-8 mission Friday, a NASA astronaut experienced a medical issue," NASA reported Friday.

But today there's an update: After an overnight stay at Ascension Sacred Heart Pensacola in Florida, the NASA astronaut was released and returned to NASA's Johnson Space Center in Houston Saturday. The crew member is in good health and will resume normal post-flight reconditioning with other crew members.

As part of NASA's SpaceX Crew-8 mission [SpaceX's eighth crew-rotation mission to the ISS], the astronaut was one of four crewmates who safely splashed down aboard their SpaceX Dragon spacecraft near Pensacola on October 25. The crew members completed a 235-day mission, 232 days of which were spent aboard the International Space Station conducting scientific research.

To protect the crew member's medical privacy, specific details on the individual's condition and identity will not be shared.

Longtime Slashdot reader MattSparkes writes: NASA is working on plans to send another, much larger helicopter to Mars than Ingenuity. The "Chopper" craft would land itself after "screaming into" the planet's atmosphere at speed, before covering several kilometers a day while carrying scientific equipment. It would probably be the most graceful arrival on the red planet of any lander yet.

According to the Wall Street Journal, Boeing is weighing the sale of its space division. "The plans, which are reportedly at an early stage, could involve Boeing offloading the Starliner spacecraft and its projects supporting the International Space Station," reports The Verge. From the report: Boeing is facing a series of predicaments, including a fraud charge over 737 Max plane crashes and Starliner issues that left two astronauts at the ISS for months. Just this week, a Boeing-made satellite for Intelsat stopped working and fell apart suddenly after suffering an "anomaly."

"We're better off doing less and doing it better than doing more and not doing it well," Boeing CEO Kelly Ortberg said during an earnings call this week. "Clearly, our core of commercial airplanes and defense systems are going to stay with the Boeing Company for the long run. But there's probably some things on the fringe there that we can be more efficient with or that distract us from our main goal here."

However, sources tell the WSJ that Boeing will likely continue to oversee the Space Launch System, which will eventually help bring NASA astronauts back to the Moon. It's also reportedly expected to hang onto its commercial and military satellite businesses.
