Slashdot reader sciencehabit writes: If you've ever seen a cow staring vacantly across a field, or a pig rolling around in its own filth, you might not think there's a lot going on in their head. You wouldn't be alone. People haven't given much credence to the intelligence of farm animals, and neither have scientists. But that's starting to change.

A growing field of research is showing that—when it comes to the minds of goats, cows, and other livestock—we may have been missing something big. Studies published over the past few years have shown that pigs show signs of empathy, goats rival dogs in some tests of social intelligence, and cows can be potty trained.

Much of this work is being carried out at the Research Institute for Farm Animal Biology (FBN) in Dummerstorf, Germany, one of the world's leading centers for investigating the minds of creatures that often end up on our dinner plate. From cows making friends to goats exhibiting signs of altruism, farm animals are upending popular—and scientific—conceptions of what's going on in their minds.

The work may not just rewrite our thinking about livestock, it might also change how we treat them. As Jan Langbein, an applied ethologist at FBN told says, 'If we don't understand how these animals think, then we won't understand what they need. And if we don't understand what they need, we can't design better environments for them.'

The New Yorker looks at 41-year-old Amabel Holland, an autistic board-game designer who "thinks about the world in terms of systems," and realized you could make a board game about almost anything, "and, when you did, its rules could both mirror and analyze the subject on which it was based."

They've since designed more than 60 games, and the article notes that Holland's work, "which is part of a larger turn toward complexity in the industry, often tackles historical and social subjects — death, religion, misinformation — using surprising 'mechanics,' or building blocks of game play, to immerse players in an experience." "With every game, you build a certain model of the world," Reiner Knizia, a former mathematician who's designed more than eight hundred games, told me. Several of his games illustrate market forces: in Modern Art, for instance, you play as auctioneers and buyers, hoping to buy low and sell high. Knizia is a traditional game designer inasmuch as he aims to "bring enjoyment to the people." But Amabel sometimes aims for the opposite of enjoyment... This Guilty Land, from 2018, is about the struggle to end slavery."
Holland says their games are "meant to evoke frustration" — specifically to communicate how difficult it can be to actually achieve political progress.

Scientists have developed a vibrating pill that, when swallowed before eating, can create a feeling of fullness. The Guardian reports: The research, which has yet to be carried out in humans, shows that after 30 minutes of activity by the Vibes pill, pigs ate on average almost 40% less food in the following half hour than they did without the device, and gained weight more slowly. The Vibes name is an acronym derived from the pill's full title -- Vibrating Ingestible BioElectronic Stimulator. The work in pigs suggests the vibrations activate stretch receptors in the stomach, simulating the presence of food. This results in signals being sent to the hypothalamus in the brain via the vagus nerve, increasing levels of various hormones that give rise to a feeling of fullness and decreasing those that result in feelings of hunger.

"We envision the Vibes pill being ingested on a relatively empty stomach 20 to 30 min before anticipated meals to trigger the desired sensation of satiety early in the meal,â the team write, adding that when produced at scale, the cost of the pills is expected to be in the cents to one dollar range. The vibrations, which are powered by a battery encased in the swallowed capsule, can be triggered when stomach acid dissolves a membrane around the pill, or by a timer. The researchers say the pills, which are about the size of a large vitamin tablet, offer a non-invasive, temporary therapy, without the need for weight-loss surgery, and exit the body with other solid waste -- meaning in humans they are flushed down the toilet. However they suggest it could be possible to develop pills that are implanted, or stay in the stomach, to reduce the need for people to repeatedly take them, should they require continuing therapy.

An anonymous reader quotes a report from The Guardian: From empty glasses of sherry on the mantelpiece to sooty footprints leading to the bedroom door, evidence of Santa's existence is clearly irrefutable. Yet most children will begin to question it at some point -- and many parents anticipate this moment with dread. Now psychologists have identified the average age when Santa skepticism creeps in, and which children are at greatest risk of harboring negative feelings when it does.

While most adults have fallen for the myth that Santa doesn't exist, many children still believe -- even if the idea of a single individual visiting the homes of billions of children in a single night is at odds with their wider reasoning skills. Dr Candice Mills, a psychologist at the University of Texas in Dallas, US, and a Santa sceptic, said: "Children typically begin to distinguish fantasy from reality during the preschool years, but their belief in the existence of a singular magical Santa Claus often continues into middle childhood." [...] To better understand this shift from belief to disbelief and children's experiences of it, Mills and her colleagues interviewed 48 six- to 15-year-olds who had stopped believing in Santa and 44 of their parents, plus a further 383 adults.

The research, which has not yet been peer reviewed, found that for most children, disbelief crept in gradually about the age of eight -- although some three- or four-year-olds had convinced themselves that Santa wasn't real, while other children believed in him until they were 15 or 16. In many cases, it was testimony from other disbelievers that finally crushed their faith. Mills said: "They may have had some skepticism based on logical reasoning -- like how can Santa Claus really get around the world in one night? -- but what pushes them over the edge is a classmate at school saying he's not real."

An anonymous reader shares a report: It may be the season of loving and giving, but doctors have warned against embracing this spirit too enthusiastically -- at least where sexual relations are concerned. They have discovered that the Christmas period is associated with a significantly increased risk of penile fractures -- a medical emergency in which the erection-producing regions of the penis snap, usually as a result of forceful bending during over-enthusiastic sexual intercourse. "This injury tends to occur during wild sex -- particularly in positions where you're not in direct eye contact [with your partner], such as the reverse cowgirl," said Dr Nikolaos Pyrgides, a urologist at the Ludwig Maximilian University of Munich, who led the research.

The fractures are often heralded by an audible crack, followed by severe pain, rapid loss of erection and severe swelling and bruising. "When [patients] present to their doctor their penis often looks like an eggplant," Pyrgides said. Suspecting that the intimacy and euphoria of the festive season might be a risk factor for this type of injury, Pyrgides and his colleagues examined hospital data for 3,421 men who sustained penile fractures in Germany between 2005 and 2021. The study -- the first to explore seasonal patterns for this type of injury -- found that such injuries were indeed more common over Christmas. In fact, "if every day was like Christmas, 43% more penile fractures would have occurred in Germany from 2005 on," Pyrgides said. The research, which was published in the British Journal of Urology International, also found the risk increased at weekends and over the summer holidays. However, New Year's Eve was not associated with an increased incidence of penis injuries.

In 2005, the reclassification of pseudoephedrine to behind-the-counter status led to widespread use of oral phenylephrine in OTC decongestants, despite evidence of its ineffectiveness. Randy Hatton, a clinical professor in the College of Pharmacy at the University of Florida, and his colleague worked to bring this issue to the FDA's attention, revealing loopholes in the regulatory process for older OTC drugs. Hatton writes in an opinion piece for Scientific American: Before the FDA required that drugs had to be proven effective, it determined whether OTC drugs were effective through expert panels that reviewed existing data. These OTC monographs establish what older OTC ingredients can be marketed without FDA approval. The oral decongestant monograph panel reviewed a few published studies and multiple unpublished studies for phenylephrine. Of the unpublished studies, only four studies showed oral phenylephrine was effective, while seven showed it was no better than placebo. We requested copies of all evidence used by the nasal decongestant review panel via a Freedom of Information Act request and performed a systematic review and meta-analysis ourselves. [...]

The FDA has multiple regulatory processes for different types of medicinal compounds. People are perhaps most familiar with the New Drug Application process, which leads to clinical trials for prescription drug approvals. However, many OTC or nonprescription drugs are regulated differently. In fact, a law passed in 1951, the Durham-Humphrey Amendment to the 1938 Food, Drug, and Cosmetic Act, created the categories of prescription and nonprescription drugs. In 1962, the act was amended again so that drugs had to be shown to be effective, hence the requirement for well-done clinical trials. But what about the drugs that were approved before 1962? This is the loophole that some OTC drugs fall through. For prescription drugs, FDA tried to address pre-1962 approvals through a review of over 3,000 prescription drugs. Most of those drugs have now been reviewed and addressed, but there are still unapproved prescription drugs on the market today, such as an extended-release form of oral nitroglycerin. For nonprescription drugs, FDA established the OTC monograph process 10 years after the 1962 amendment to the Food, Drug, and Cosmetic Act, which required products not proven effective to be reconsidered. FDA formed advisory panels grouping hundreds of ingredients into 26 categories based on the products' uses. After gathering all available information, both published and unpublished, from manufacturers, the advisory panels issued final reports to FDA about whether these ingredients were GRASE (generally recognized as safe and effective), not GRASE, or inconclusive. GRASE ingredients can be used in nonprescription drugs without FDA approval if the use matches the monograph. "The oral phenylephrine example shows that FDA needs more funding to look at these old drugs," concludes Hatton. "We need public funds to support independent researchers who want to examine these products objectively. The government should be able to spend millions to save consumers billions on ineffective products. Companies that market these products have no incentive to prove they don't work. Nonprescription drugs must be effective -- not just safe."

During a meeting of the National Space Council, Vice President Kamala Harris said an international astronaut will land on the Moon during one of NASA's Artemis missions. "Today, in recognition of the essential role that our allies and partners play in the Artemis program, I am proud to announce that alongside American astronauts, we intend to land an international astronaut on the surface of the Moon by the end of the decade," Harris said. Ars Technica reports: Although the National Space Council is useful in aggregating disparate interests across the US government to help form more cohesive space policies, public meetings like the one Wednesday can seem perfunctory. Harris departed the stage soon after her speech, and other government officials read from prepared remarks during the rest of the event. Nevertheless, Harris' announcement highlighted the role the space program plays in elevating the soft power of the United States. It was widely assumed an international astronaut would eventually land on the Moon with NASA. Harris put a deadline on achieving this goal.

NASA has long included astronauts from its international partners on human spaceflight missions, dating back to the ninth flight of the space shuttle in 1983, when West German astronaut Ulf Merbold joined five Americans on a flight to low-Earth orbit. This was seen by US government officials as a way to foster closer relations with like-minded countries. The inclusion of foreign astronauts on US missions also repays partner nations who make financial commitments to US-led space projects with a high-profile flight opportunity for one of their citizens.

Among the international partners contributing to Artemis, it seems most likely a European astronaut would get the first slot for a landing with NASA. ESA funded the development of the service modules used on NASA's Orion spacecraft, which will ferry astronauts from Earth to the Moon and back. These modules provide power and propulsion for Orion. ESA is also developing refueling and communications infrastructure for the Gateway mini-space station to be constructed in orbit around the Moon.

A Japanese astronaut might also have a shot at getting a seat on an Artemis landing. Japan's government has committed to providing the life-support system for the Gateway's international habitation module, along with resupply services to deliver cargo to Gateway. Japan is also interested in building a pressurized rover for astronauts to drive across the lunar surface. In recognition of Japan's contributions, NASA last year committed to flying a Japanese astronaut aboard Gateway. Canada is building a robotic arm for Gateway, but a Canadian astronaut already has a seat on NASA's first crewed Artemis mission, albeit without a trip to the lunar surface.

An anonymous reader quotes a report from the Los Angeles Times: It was the late 1980s when Gary Mund felt his pinky tremble. At first it seemed like a random occurrence, but pretty quickly he realized something was seriously wrong. Within two years, Mund -- a crew worker with the Eastern Municipal Water District in Riverside County -- was diagnosed with Parkinson's disease. The illness would eventually consume much of his life, clouding his speech, zapping most of his motor skills and taking away his ability to work and drive. "It sucks," said Mund, 69. He speaks tersely, because every word is a hard-won battle. "I was told the herbicide wouldn't hurt you."

The herbicide is paraquat, an extremely powerful weed killer that Mund sprayed on vegetation as part of his job from about 1980 to 1985. Mund contends the product is responsible for his disease, but the manufacturer denies there is a causal link between the chemical and Parkinson's. Paraquat is manufactured by Syngenta, a Swiss-based company owned by the Chinese government. The chemical is banned in at least 58 countries -- including China and Switzerland -- due to its toxicity, yet it continues to be a popular herbicide in California and other parts of the United States. But research suggests the chemical may cross the blood-brain barrier in a manner that triggers Parkinson's disease, a progressive, neurodegenerative disorder that affects movement. Now, Mund is among thousands of workers suing Syngenta seeking damages and hoping to see the chemical banned.

Since 2017, more than 3,600 lawsuits have been filed in state and federal courts seeking damages from exposure to paraquat products, according to Syngenta's 2022 financial report (PDF). [...] Paraquat is 28 times more toxic than another controversial herbicide, Roundup, according to a report from the Pesticide Action Network. (Roundup has been banned in several parts of California, including a 2019 moratorium by the Los Angeles County Board of Supervisors forbidding its use by county departments.) Paraquat also has other known health effects. It is listed as "highly toxic" on the U.S. Environmental Protection Agency's website, which says that "one small sip can be fatal and there is no antidote." The EPA is currently reviewing paraquat's approval status. However, both the EPA and Syngenta cited a 2020 U.S. government Agricultural Health Study that found there is no clear link between paraquat exposure and Parkinson's disease. A 2021 review of reviews similarly found that there is no causal relationship.

An anonymous reader quotes a report from Ars Technica: With redesigned engine components, Blue Origin's New Shepard rocket took off from West Texas and flew to the edge of space on Tuesday with a package of scientific research and technology demonstration experiments. This was the first flight of Blue Origin's 60-foot-tall (18-meter) New Shepard rocket since September 12, 2022, when an engine failure destroyed the booster and triggered an in-flight abort for the vehicle's pressurized capsule. There were no passengers aboard for that mission, and the capsule safely separated from the failed booster and parachuted to a controlled landing.

The flight on Tuesday also didn't carry people. Instead, Blue Origin, Jeff Bezos's space company, lofted 33 payloads from NASA, research institutions, and commercial companies. Some of these payloads were flown again on Tuesday's launch after failing to reach space on the failed New Shepard mission last year. Among these payloads were an experiment to demonstrate hydrogen fuel cell technology in microgravity and an investigation studying the strength of planetary soils under different gravity conditions. Blue Origin's capsule, mounted on top of the rocket, also flew 38,000 postcards submitted by students through Club for the Future, the company's nonprofit.

For Tuesday's return-to-flight mission, the New Shepard rocket ignited its BE-3PM engine and climbed away from Blue Origin's remote launch site near Van Horn, Texas, at 10:42 am CST (16:42 UTC). The hydrogen-fueled engine fired for more than two minutes, then shut down as scheduled as the rocket continued coasting upward, reaching an altitude of more than 347,000 feet (106 kilometers). The booster returned for a precision propulsive landing a short distance from the launch pad, and Blue Origin's capsule deployed three parachutes to settle onto the desert floor, completing a 10-minute up-and-down flight. Blue Origin has launched 24 missions with its reusable New Shepard rocket, including six flights carrying people just over the Karman line, the internationally recognized boundary of space 100 kilometers above Earth.

NASA has successfully beamed an ultra-high definition streaming video from a record-setting 19 million miles away. The Deep Space Optical Communications experiment, as it is called, is part of a NASA technology demonstration aimed at streaming HD video from deep space to enable future human missions beyond Earth orbit. From a NASA press release: The [15-second test] video signal took 101 seconds to reach Earth, sent at the system's maximum bit rate of 267 megabits per second (Mbps). Capable of sending and receiving near-infrared signals, the instrument beamed an encoded near-infrared laser to the Hale Telescope at Caltech's Palomar Observatory in San Diego County, California, where it was downloaded. Each frame from the looping video was then sent "live" to NASA's Jet Propulsion Laboratory in Southern California, where the video was played in real time.

The laser communications demo, which launched with NASA's Psyche mission on Oct. 13, is designed to transmit data from deep space at rates 10 to 100 times greater than the state-of-the-art radio frequency systems used by deep space missions today. As Psyche travels to the main asteroid belt between Mars and Jupiter, the technology demonstration will send high-data-rate signals as far out as the Red Planet's greatest distance from Earth. In doing so, it paves the way for higher-data-rate communications capable of sending complex scientific information, high-definition imagery, and video in support of humanity's next giant leap: sending humans to Mars.

Uploaded before launch, the short ultra-high definition video features an orange tabby cat named Taters, the pet of a JPL employee, chasing a laser pointer, with overlayed graphics. The graphics illustrate several features from the tech demo, such as Psyche's orbital path, Palomar's telescope dome, and technical information about the laser and its data bit rate. Tater's heart rate, color, and breed are also on display. There's also a historical link: Beginning in 1928, a small statue of the popular cartoon character Felix the Cat was featured in television test broadcast transmissions. Today, cat videos and memes are some of the most popular content online. "Despite transmitting from millions of miles away, it was able to send the video faster than most broadband internet connections," said Ryan Rogalin, the project's receiver electronics lead at JPL. "In fact, after receiving the video at Palomar, it was sent to JPL over the internet, and that connection was slower than the signal coming from deep space. JPL's DesignLab did an amazing job helping us showcase this technology -- everyone loves Taters."

Using a "recently refurbished" telescope array, SETI scientists performed 541 hours of additional observations — and found 35 new "Fast Radio Bursts" (or FRBs). SciTechDaily reports: All 35 FRBs were found in the lower part of the frequency spectrum, each with its unique energy signature. "This work is exciting because it provides both confirmation of known FRB properties and the discovery of some new ones," said the SETI Institute's Dr. Sofia Sheikh, NSF MPS-Ascend Postdoctoral Fellow and lead author. "We're narrowing down the source of FRBs, for example, to extreme objects such as magnetars, but no existing model can explain all of the properties that have been observed so far. It has been wonderful to be part of the first FRB study done with the Allen Telescope Array — this work proves that new telescopes with unique capabilities, like the Allen Telescope Array, can provide a new angle on outstanding mysteries in FRB science."

The detailed findings, recently published in the journal Monthly Notices of the Royal Astronomical Society (MNRAS), showcase the intriguing behaviors of FRBs. These mysterious signals exhibit downward frequency drifting, a connection between their bandwidth and center frequency, and changes in burst duration over time. The team also observed something that had never been reported before: there was a noticeable drop in the center frequency of bursts over the two months of observation, revealing an unexpected cosmic slide-whistle...

No clear pattern was found, highlighting the unpredictability of these celestial phenomena.
SETI says its Allen Telescope Array (or ATA) was custom-built for SETI searches, "thanks to the interest and benevolence of many donors, including technologists Paul Allen (co-founder of Microsoft) and Nathan Myhrvold (former Chief Technology Officer for Microsoft)." The Allen Telescope Array offers SETI scientists access to an instrument seven days a week, and permits the search of several different targets (usually nearby star systems) simultaneously. This can result in a speed-up of SETI searches by a factor of at least 100.

A system of lagoons has been discovered in Argentina hosting a rare range of microbial communities previously unknown to scientists. The microbial communities form giant mounds of rock as they grow — like corals building a reef millimeter by millimeter. And the University of Colorado points out that "the communities could also provide scientists with an unprecedented look at how life may have arisen on Mars, which resembled Earth billions of years ago."

"If life ever evolved on Mars to the level of fossils, it would have been like this," said geologist Brian Hynek, a professor in the department of geological sciences at the University of Colorado Boulder, who helped document the ecosystem. "Understanding these modern communities on Earth could inform us about what we should look for as we search for similar features in the Martian rocks."
more details from CNN: Stromatolites are layered rocks created by the growth of blue-green algae, or cyanobacteria, through photosynthesis. The structures are considered to be one of the oldest ecosystems on Earth, according to NASA, representing the earliest fossil evidence for life on our planet from at least 3.5 billion years ago. "These are certainly akin to some of the earliest macrofossils on our planet, and in really a rare type of environment on modern Earth," said Hynek...

While the stromatolites are in an environment containing oxygen, Hynek said he believes the layers farther down in the rock have little to no access to oxygen and are actively formed by microbes using anoxygenic photosynthesis. This would make the structures similar to the ones found on ancient Earth... "We've identified more than 600 ancient lakes on Mars; there may have even been an ocean. So, it was a lot more Earth-like early on," he said.

Of the 15,000 satellites humans have sent into space, "just over half are still functioning," reports CNN. "The rest, after running out of fuel and ending their serviceable life, have either burned up in the atmosphere or are still orbiting the planet as useless hunks of metal" — scattering "an aura of space junk around the planet."

"One way to start tackling the problem would be to stop producing more junk — by refueling satellites rather than decommissioning them once they run out of power." "Right now you can't refuel a satellite on orbit," says Daniel Faber, CEO of Orbit Fab. But his Colorado-based company wants to change that... "The lack of fuel creates a whole paradigm where people design their spacecraft missions around moving as little as possible. That means that we can't have tow trucks in orbit to get rid of any debris that happens to be left. We can't have repairs and maintenance, we can't upgrade anything. We can't inspect anything if it breaks. There are so many things we can't do and we operate in a very constrained way. That's the solution we're trying to deliver...."

Orbit Fab has no plans to address the existing fleet of satellites. Instead, it wants to focus on those that have yet to launch, and equip them with a standardized port — called RAFTI, for Rapid Attachable Fluid Transfer Interface — which would dramatically simplify the refueling operation, keeping the price tag down. "What we're looking at doing is creating a low-cost architecture," says Faber. "There's no commercially available fuel port for refueling a satellite in orbit yet. For all the big aspirations we have about a bustling space economy, really, what we're working on is the gas cap — we are a gas cap company." Orbit Fab, which advertises itself with the tagline "gas stations in space," is working on a system that includes the fuel port, refueling shuttles — which would deliver the fuel to a satellite in need — and refueling tankers, or orbital gas stations, which the shuttles could pick up the fuel from. It has advertised a price of $20 million for on-orbit delivery of hydrazine, the most common satellite propellant.

In 2018, the company launched two testbeds to the International Space Station to test the interfaces, the pumps and the plumbing. In 2021 it launched Tanker-001 Tenzing, a fuel depot demonstrator that informed the design of the current hardware. The next launch is now scheduled for 2024. "We are delivering fuel in geostationary orbit for a mission that is being undertaken by the Air Force Research Lab," says Faber. "At the moment, they're treating it as a demonstration, but it's getting a lot of interest from across the US government, from people that realize the value of refueling." Orbit Fab's first private customer will be Astroscale, a Japanese satellite servicing company that has developed the first satellite designed for refueling. Called LEXI, it will mount RAFTI ports and is currently scheduled to launch in 2026.

According to Simone D'Amico, an associate professor of astronautics at Stanford University, who's not affiliated with Orbit Fab, on-orbit servicing is one of the keys to ensuring a safe and sustainable development of space... "The development of space infrastructure and the proliferation of space assets is reaching a critical volume that is not sustainable anymore without a change of paradigm."
"In 10 or 15 years, we'd like to be building refineries in orbit," CEO Faber tells CNN, "processing material that is launched from the ground into a range of chemicals that people want to buy: air and water for commercial space stations, 3D printer feedstock minerals to grow plants. We want to be the industrial chemical supplier to the emerging commercial space industry."

The Washington Post reports that America's largest pharmacy chains have "handed over Americans' prescription records to police and government investigators without a warrant, a congressional investigation found, raising concerns about threats to medical privacy." Though some of the chains require their lawyers to review law enforcement requests, three of the largest — CVS Health, Kroger and Rite Aid, with a combined 60,000 locations nationwide — said they allow pharmacy staff members to hand over customers' medical records in the store... Pharmacies' records hold some of the most intimate details of their customers' personal lives, including years-old medical conditions and the prescriptions they take for mental health and birth control. Because the chains often share records across all locations, a pharmacy in one state can access a person's medical history from states with more-restrictive laws. Carly Zubrzycki, an associate professor at the University of Connecticut law school, wrote last year that this could link a person's out-of-state medical care via a "digital trail" back to their home state...

In briefings, officials with eight American pharmacy giants — Walgreens Boots Alliance, CVS, Walmart, Rite Aid, Kroger, Cigna, Optum Rx and Amazon Pharmacy — told congressional investigators that they required only a subpoena, not a warrant, to share the records.

A subpoena can be issued by a government agency and, unlike a court order or warrant, does not require a judge's approval. To obtain a warrant, law enforcement must convince a judge that the information is vital to investigate a crime. Officials with CVS, Kroger and Rite Aid said they instruct their pharmacy staff members to process law enforcement requests on the spot, saying the staff members face "extreme pressure to immediately respond," the lawmakers' letter said. The eight pharmacy giants told congressional investigators that they collectively received tens of thousands of legal demands every year, and that most were in connection with civil lawsuits. It's unclear how many were related to law enforcement demands, or how many requests were fulfilled.

Only one of the companies, Amazon, said it notified customers when law enforcement demanded its pharmacy records unless there was a legal prohibition, such as a "gag order," preventing it from doing so, the lawmakers said...

Most investigative requests come with a directive requiring the company to keep them confidential, a CVS spokeswoman said; for those that don't, the company considers "on a case-by-case basis whether it's appropriate to notify the individual."
The article points out that Americans "can request the companies tell them if they've ever disclosed their data...but very few people do.

"CVS, which has more than 40,000 pharmacists and 10,000 stores in the United States, said it received a 'single-digit number' of such consumer requests last year, the letter states."

An anonymous reader shared this report from CNN: Scientists have long viewed Saturn's moon Enceladus, which harbors an ocean beneath its thick, icy shell, as one of the best places to search for life beyond Earth. Now, a new analysis of data collected by NASA's Cassini mission, which orbited Saturn and its moons between 2004 and 2017, has uncovered intriguing evidence that further supports the idea of Enceladus as a habitable ocean world.

Enceladus initially captured the attention of scientists in 2005 because plumes of ice grains and water vapor were observed rising through cracks in the moon's ice shell and releasing into space. The spacecraft flew through the plumes and "sampled" them, with data suggesting the presence of organic compounds within the plumes, some of which are key for life. The latest data analysis of Cassini's flybys of Enceladus revealed the detection of a molecule called hydrogen cyanide that's toxic to humans but crucial to processes driving the origin of life. What's more, the team also found evidence to support that Enceladus' ocean has organic compounds that provide a source of chemical energy that could potentially be used as powerful fuel for any form of life...

The combination of these elements together suggested a process called methanogenesis, or the metabolic creation of methane, may be at play on Enceladus. Scientists suspect methanogenesis may have also played out on early Earth, contributing to the origin of life. But the new research indicates more varied and powerful chemical energy sources are occurring within Enceladus' ocean... Now, the study authors want to investigate how diluted the organic compounds are within the subsurface ocean because the dilution of these compounds could determine whether Enceladus could support life. In the future, astronomers hope to send a dedicated mission to investigate Enceladus, which could provide a definitive answer as to whether life exists in the ocean world.
"Our work provides further evidence that Enceladus is host to some of the most important molecules for both creating the building blocks of life and for sustaining that life through metabolic reactions," accoding to one of the study's lead authors.

"Not only does Enceladus seem to meet the basic requirements for habitability, we now have an idea about how complex biomolecules could form there, and what sort of chemical pathways might be involved."

An anonymous reader shared this report from CNN: The quest for new antibiotics is going back to the Stone Age. The urgency to identify possible candidates has never been greater as the global population faces nearly 5 million deaths every year that are associated with microbial resistance, according to the World Health Organization. A research team led by bioengineering pioneer César de la Fuente is using artificial intelligence-based computational methods to mine genetic information from extinct human relatives such as Neanderthals and long-gone ice age creatures such as the woolly mammoth and giant sloth. The scientists say some of these small protein, or peptide, molecules they have identified have bacteria-fighting powers that may inspire new drugs to fight infections in humans. The innovative work also opens up a completely new way to think about drug discovery.

"It has enabled us to uncover new sequences, new types of molecules that we have not previously found in living organisms, expanding the way we think about molecular diversity," said de la Fuente, Presidential Assistant Professor at the University of Pennsylvania, where he heads the machine biology group. "Bacteria from today have never faced those molecules so they may give us a better opportunity at targeting the pathogens that are problematic today...." The idea to look at extinct molecules came up during a lab brainstorm when the blockbuster movie "Jurassic Park" was mentioned. "The notion (in the film) was to bring back entire organisms, and obviously, they had a lot of issues," De la Fuente said. His team started thinking about a more feasible idea: "Why not bring back molecules from the past?" Advances in the recovery of ancient DNA from fossils mean that detailed libraries of genetic information about extinct human relatives and long-lost animals are now publicly available...

In research expected to publish next year, de la Fuente and his colleagues have developed a new deep-learning model to explore what he describes as the "extinctome" — the protein sequences of 208 extinct organisms for which detailed genetic information is available. The team found more than 11,000 previously unknown potential antimicrobial peptides unique to extinct organisms and synthesized promising candidates... He said that the peptides they discovered displayed "excellent anti-infective activity" in mice.

"Molecular de-extinction offers a unique opportunity to combat antibiotic resistance by resurrecting and tapping into the power of molecules from the past," he said.

In 2020 a NASA spacecraft visited the asteroid Bennu. In October it returned to earth with a sample. Monday scientists got their first data about it at a meeting of the American Geophysical Union — which is a truly big deal.

"Before Earth had biology, it had chemistry," writes the Washington Post. "How the one followed from the other — how a bunch of boring molecules transformed themselves into this special thing we call life — is arguably the greatest unknown in science." The mission's top scientist, Dante Lauretta... showed slides with a long list of intriguing molecules, including carbon-based organics, in the grains and pebbles retrieved from Bennu. They will shine light on the molecular building blocks of the solar system and "maybe — still early phase — maybe insights into the origin of life." This analysis has only just started. The team has not yet released a formal scientific paper. In his lecture, Lauretta cited one interesting triangular, light-colored stone, which he said contained something he'd never seen before in a meteorite. "It's a head-scratcher right now. What is this material?" he said.

In an interview after the lecture, Lauretta said almost 5 percent of the sample is carbon. "That is a very carbon-rich sample — the richest we have in all our extraterrestrial material. ... We're still unraveling the complex organic chemistry, but it looks promising to really understand: Did these carbon-rich asteroids deliver fundamental molecules that may have gone on to contribute to the origin of life...?"

This space dirt has astrobiological import, though. By looking at prebiotic chemistry on Bennu, scientists will have a better idea what they are looking at if and when they find suspicious molecules elsewhere in the solar system, such as on Mars, Jupiter's moon Europa or Saturn's moon Enceladus. "This is almost the perfect laboratory control from non-biological chemistry," Glavin said. "This better prepares us for our search for life on Mars, or Europa or Enceladus — places that might have had life at one point."
Space.com quotes Lauretta as saying "We definitely have hydrated, organic-rich remnants from the early solar system, which is exactly what we were hoping when we first conceived this mission almost 20 years ago."

Ten years ago, a Dutch scientist unveiled a $330,000 lab-grown hamburger made from cow cells grown in petri dishes. It took six weeks to culture the patty. A chef cooked it onstage as journalists watched. Reactions ranged from "unpleasant" to "beeflike." The scientist expected supermarket sales in a decade. His company and others have since raised over $2 billion but have little to show, only recently making one pound of chicken monthly. Despite bold promises of mass production, low emissions, and better nutrition, commercial viability remains elusive. Bloomberg Business: The company [Upside Foods], in a letter from its attorney to Bloomberg Businessweek, says plans for scaling up have been an evolution saddled with "realities and complexities of doing something that has never been done before. Innovation rarely happens in a straight and continuous line."

The dream is moist, meaty flesh self-multiplying ad infinitum in high-tech, stainless steel cell-growing chambers. But according to internal company documentation and eight former employees, most of whom requested anonymity because they don't have permission to discuss confidential information, Upside at the moment is actually growing just minuscule numbers of chicken skin-type cells in small plastic bottles, then scraping them out gram by gram to compress and mold them into a single forkful of flesh. This labor-intensive chicken has higher levels of cholesterol and lead than the real thing, publicly available company documentation shows. Even if that sounds remotely desirable, some scientists say the whole energy-intensive endeavor may actually be worse for the environment, especially with chicken, which has the smallest carbon footprint of anything at the local butcher. All of which points to this question: Why exactly are we chasing lab-grown chicken?[...]

In a cavernous theater lit up with the green shapes of camels and palms at COP28 in Dubai, ecologist Thomas Crowther, former chief scientific adviser for the United Nations' Trillion Trees Campaign, was doing something he never would have expected a few years ago: begging environmental ministers to stop planting so many trees. From a report: Mass plantations are not the environmental solution they're purported to be, Crowther argued when he took the floor on December 9 for one of the summit's "Nature Day" events. The potential of newly created forests to draw down carbon is often overstated. They can be harmful to biodiversity. Above all, they are really damaging when used, as they often are, as avoidance offsets-- "as an excuse to avoid cutting emissions," Crowther said.

The popularity of planting new trees is a problem -- at least partly -- of Crowther's own making. In 2019, his lab at ETH Zurich found that the Earth had room for an additional 1.2 trillion trees, which, the lab's research suggested, could suck down as much as two-thirds of the carbon that humans have historically emitted into the atmosphere. "This highlights global tree restoration as our most effective climate change solution to date," the study said. Crowther subsequently gave dozens of interviews to that effect. This seemingly easy climate solution sparked a tree-planting craze by companies and leaders eager to burnish their green credentials without actually cutting their emissions, from Shell to Donald Trump. It also provoked a squall of criticism from scientists, who argued that the Crowther study had vastly overestimated the land suitable for forest restoration and the amount of carbon it could draw down. (The study authors later corrected the paper to say tree restoration was only "one of the most effective" solutions, and could suck down at most one-third of the atmospheric carbon, with large uncertainties.)

Crowther, who says his message was misinterpreted, put out a more nuanced paper last month, which shows that preserving existing forests can have a greater climate impact than planting trees. He then brought the results to COP28 to "kill greenwashing" of the kind that his previous study seemed to encourage -- that is, using unreliable evidence on the benefits of planting trees as an excuse to keep on emitting carbon. "Killing greenwashing doesn't mean stop investing in nature," he says. "It means doing it right. It means distributing wealth to the Indigenous populations and farmers and communities who are living with biodiversity."

In an interview with Lex Fridman, Jeff Bezos candidly acknowledged Blue Origin's slow progress (compared to SpaceX). From a report: "Blue Origin needs to be much faster, and it's one of the reasons that I left my role as the CEO of Amazon a couple of years ago," he said. "I wanted to come in, and Blue Origin needs me right now. Adding some energy, some sense of urgency. We need to move much faster. And we're going to."

How is Blue Origin going to speed up?

"We're going to become the world's most decisive company across any industry," he said. "We're going to get really good at taking appropriate technology risks, making those decisions quickly. You know, being bold on those things. And having the right culture that supports that. You need people to be ambitious, technically ambitious. If there are five ways to do something, we'll study them, but let's go through them very quickly and make a decision. We can always change our mind."
