It's one of America's best hospitals — a nonprofit "academic medical center" called the Cleveland Clinic. And this week it installed an IBM-managed quantum computer to accelerate healthcare research (according to an announcement from IBM). IBM is calling it "the first quantum computer in the world to be uniquely dedicated to healthcare research."

The clinic's CEO said the technology "holds tremendous promise in revolutionizing healthcare and expediting progress toward new cares, cures and solutions for patients." IBM's CEO added that "By combining the power of quantum computing, artificial intelligence and other next-generation technologies with Cleveland Clinic's world-renowned leadership in healthcare and life sciences, we hope to ignite a new era of accelerated discovery."

em>Inside HPC points out that "IBM Quantum System One" is part of a larger biomedical research program applying high-performance computing, AI, and quantum computing, with IBM and the Cleveland Clinic "collaborating closely on a robust portfolio of projects with these advanced technologies to generate and analyze massive amounts of data to enhance research." The Cleveland Clinic-IBM Discovery Accelerator has generated multiple projects that leverage the latest in quantum computing, AI and hybrid cloud to help expedite discoveries in biomedical research. These include:

- Development of quantum computing pipelines to screen and optimize drugs targeted to specific proteins;

- Improvement of a quantum-enhanced prediction model for cardiovascular risk following non-cardiac surgery;

- Application of artificial intelligence to search genome sequencing findings and large drug-target databases to find effective, existing drugs that could help patients with Alzheimer's and other diseases.


The Discovery Accelerator also serves as the technology foundation for Cleveland Clinic's Global Center for Pathogen & Human Health Research, part of the Cleveland Innovation District. The center, supported by a $500 million investment from the State of Ohio, Jobs Ohio and Cleveland Clinic, brings together a team focused on studying, preparing and protecting against emerging pathogens and virus-related diseases. Through the Discovery Accelerator, researchers are leveraging advanced computational technology to expedite critical research into treatments and vaccines.

IHTFISP shares a report from Phys.Org: A quartet of mathematicians from Yorkshire University, the University of Cambridge, the University of Waterloo and the University of Arkansas has discovered a 2D geometric shape that does not repeat itself when tiled. David Smith, Joseph Samuel Myers, Craig Kaplan and Chaim Goodman-Strauss have written a paper describing how they discovered the unique shape and possible uses for it. Their full paper is available on the arXiv preprint server. [...]

The shape has 13 sides and the team refers to it simply as "the hat." They found it by first paring down possibilities using a computer and then by studying the resulting smaller sets by hand. Once they had what they believed was a good possibility, they tested it using a combinatorial software program -- and followed that up by proving the shape was aperiodic using a geometric incommensurability argument. The researchers close by suggesting that the most likely application of the hat is in the arts.

An anonymous reader quotes a report from Science Magazine: In an unusual move, the U.S. Department of Energy (DOE) has quietly begun a new competition for the contract to run the United States's sole dedicated particle physics laboratory. Announced in January, the rebid comes 1 year after Fermi National Accelerator Laboratory (Fermilab), which is managed in part by the University of Chicago (UChicago), failed an annual DOE performance review and 9 months after it named a new director. DOE would not comment, but observers say its frustrations include cost increases and delays in a gargantuan new neutrino experiment.

"I don't think it's surprising at all given the department's evaluation of [Fermilab's] performance," says James Decker, a physicist and consultant with Decker, Garman, Sullivan & Associates, LLC, who served as principal deputy director of DOE's Office of Science from 1973 to 2007. Although Fermilab passed its 2022 performance evaluation, the one for fiscal year 2021 was "one of the most scathing I have seen," Decker says.

DOE has already solicited letters of interest and will issue a request for formal proposals this summer. It intends to award the new contract by the end of the next fiscal year, 30 September 2024, and transfer control of the lab, which employs 2100 staff and has an annual budget of $614 million, on January 1, 2025. UChicago hopes to win the contract again, says Paul Alivisatos, president of the university, who is also chair of FRA's board of directors and a former director of DOE's Lawrence Berkeley National Laboratory. "We absolutely will be bidding to continue." [...] How many parties will bid on the contract remains unclear. Managing the lab requires very specific technical expertise but pays $5 million per year, at most. "I don't think that there are too many organizations that could really compete for this contract," Decker says. If just UChicago or URA bid on the new contract, they'll need a new partner, multiple observers say, perhaps one with expertise in huge construction projects. DOE is sure to insist that something changes.

Dozens of the world's largest natural history museums revealed on Thursday a survey of everything in their collections. The global inventory is made up of 1.1 billion objects that range from dinosaur skulls to pollen grains to mosquitoes. The New York Times reports: The survey's organizers, who described the effort in the journal Science, said they hoped the survey would help museums join forces to answer pressing questions, such as how quickly species are becoming extinct and how climate change is altering the natural world. "It gives us intelligence now to start thinking about things that museums can do together that we wouldn't have conceived of before," said Kirk Johnson, the director of the Smithsonian National Museum of Natural History in Washington and one of the leaders of the project. "It's the argument for networking the global museum."

Scientists had created smaller inventory databases before. But the new effort, which included 73 museums in 28 countries, was unparalleled, experts said. The survey revealed important gaps in the world's collections. Relatively few objects come from the regions around the earth's poles, which are especially vulnerable to the impact of global warming, for example. Insects, the most diverse group of animal species, were also underrepresented.

"The analysis is at a global scale that no one else has managed," said Emily Meineke, an entomologist at the University of California, Davis, who was not involved in the survey. Dr. Meineke said that this survey of large institutions also laid the groundwork for surveys of smaller ones, which might hold even more surprises. "Once these methods are applied down the line to smaller collections, the results are likely to give us a truer picture of biodiversity globally," she said.

British satellite company OneWeb is gearing up for the launch of its final batch of internet satellites, completing a constellation in low Earth orbit despite some hiccups along the way. Gizmodo reports: India's heaviest launch vehicle LVM-3 will carry 36 OneWeb satellites, with liftoff slated for Sunday at 11:30 p.m. ET, according to OneWeb. The launch will take place at the Satish Dhawan Space Centre in Sriharikota, India, marking OneWeb's second deployment from India. You can watch the launch at the livestream [here].

OneWeb has been building an internet constellation in low Earth orbit since 2020, and it currently consists of 579 functioning satellites, according to statistics kept by Harvard-Smithsonian astrophysicist Jonathan McDowell. The addition of 36 new units will raise the population of the constellation to 615, completing the first orbital shell. The company had originally planned on building a 648-unit constellation, but it says this final launch will cap it off and allow for global coverage.

Pets could be subjected to gene editing under a new UK government act, the RSPCA has warned. From a report: The animal charity has said that the Genetic Technology (Precision Breeding) Act applies to all vertebrate animals, not only farmed animals, and that it could lead to cats and dogs being gene-edited to include extreme features. The law allows the creation and marketing of "precision-bred" or genome-edited plants and vertebrate animals in England. The government said it would allow farmers to grow crops that are drought- and disease-resistant, reduce the use of fertilisers and pesticides, and help breed animals that are protected from catching harmful diseases.

The UK environment secretary, Therese Coffey, described the act, which received royal assent on Thursday, as a "Brexit freedom," but the RSPCA said it could have dire consequences for animal welfare. David Bowles, the head of campaigns and public affairs at the RSPCA, criticised what he described as an "ill-judged policy." He said the charity had tried to get the government to include an exemption for pets, but was "sadly ignored." He added: "Gene editing could be a huge step backwards for animals. We do not believe this act should include animals, whether they are farm, pet or wildlife. Invasive procedures are needed to create each line of gene-edited mammals, there is no history of use for this powerful technology, and it can cause unintended changes to the genome, with unpredictable effects. The RSPCA has serious animal welfare and ethical concerns about this."

Scientists have come up with a simple explanation for the strange movements of our solar system's first known visitor from another star. NPR reports: Now, though, in the journal Nature, two researchers say the answer might be the release of hydrogen from trapped reserves inside water-rich ice. That was the notion of Jennifer Bergner, an astrochemist with the University of California, Berkeley, who recalls that she initially didn't spend much time thinking about 'Oumuamua when it was first discovered. "It's not that closely related to my field. So I was like, this is a really intriguing object, but sort of moved on with my life," she says. Then she happened to attend a seminar that featured Cornell University's Darryl Seligman, who described the object's weirdness and what might account for it. One possibility he'd considered was that it was composed entirely of hydrogen ice. Others have suggested it might instead be composed of nitrogen ice.

Bergner wondered if it could just be a water-rich comet that got exposed to a lot of cosmic radiation. That radiation would release the hydrogen from the water. Then, if that hydrogen got trapped inside the ice, it could be released when the object approached the sun and began to warm up. Astronomers who observed 'Oumuamua weren't looking for that kind of hydrogen outgassing and, even if they had been, the amounts involved could have been undetectable from Earth. She teamed up with Seligman to start investigating what happens when water ice gets hit with radiation. They also did calculations to see if the object was large enough to store enough trapped hydrogen to account for the observed acceleration. And they looked to see how the structure of water ice would react to getting warmed, to see if small shifts could allow trapped gas to escape.

It turns out, this actually could account for the observed acceleration, says Bergner, who notes that the kind of "amorphous" water ice found in space has a kind of "fluffy" structure that contains empty pockets where gas can collect. As this water ice warms up, its structure begins to rearrange, she says, and "you lose your pockets for hiding hydrogen. You can form channels or cracks within the water ice as parts of it are sort of compacting." As the pockets collapse and these cracks form, the trapped hydrogen would leak out into space, giving the object a push, she says.

Longtime Slashdot reader destinyland shares a report from Space.com: The Relativity Space rocket, called Terran 1, lifted off from Launch Complex 16 at Florida's Cape Canaveral Space Force Station at 8:25 p.m. EST (0025 GMT on March 23), kicking off a test flight called "Good Luck, Have Fun" (GLHF). Terran 1 performed well initially. For example, it survived Max-Q -- the part of flight during which the structural loads are highest on a rocket -- and its first and second stages separated successfully. But something went wrong shortly thereafter, at around three minutes into the flight, when the rocket failed to reach orbit.

"No one's ever attempted to launch a 3D-printed rocket into orbit, and, while we didn't make it all the way today, we gathered enough data to show that flying 3D-printed rockets is viable," Relativity Space's Arwa Tizani Kelly said during the company's launch webcast on Wednesday night. "We just completed a major step in proving to the world that 3D-printed rockets are structurally viable," she added.

An anonymous reader quotes a report from CBS News: The Food and Drug Administration on Monday cleared cultured "cultured chicken cell material" made by GOOD Meat as safe for use as human food. While the FDA said the lab-grown chicken was safe to eat, GOOD Meat still needs approval from the Agriculture Department before i can sell the product in the U.S. If approved, acclaimed chef Jose Andres plans to serve GOOD Meat's chicken to customers at his Washington, D.C. restaurant. He's on GOOD Meat's board of directors.

The FDA previously gave the green light to lab-grown chicken made by Upside Foods in November. Upside Foods and GOOD Meat both use cells from chickens to create the cultured chicken products. Once cells are extracted, GOOD Meat picks the cells most likely to produce healthy, sustainable and tasty meat, the company explained. The cells are immersed in nutrients inside a tank. They grow and divide, creating the cultured chicken, which can be harvested after four to six weeks. GOOD Meat's chicken is already sold in Singapore. "Today's news is more than just another regulatory decision -- it's food system transformation in action," says Bruce Friedrich, president and founder of the Good Food Institute, a non-profit think tank that focuses on alternatives to traditional meat production.

"Consumers and future generations deserve the foods they love made more sustainably and in ways that benefit the public good -- ways that preserve our land and water, ways that protect our climate and global health," Friedrich says.

Careful scrutiny of the debris from the impact of NASA's DART mission into Dimorphos has not found any evidence for water-ice on the asteroid, nor the residue of thruster fuel from the spacecraft, new results from the European Southern Observatory (ESO) show. Space.com reports: However, the data from the MUSE (Multi-Unit Spectroscopic Explorer) instrument on ESO's Very Large Telescope in Chile does indicate differences in the size of particles in the debris, and show how the polarization of the light from the asteroid changed. These could both reveal details about the nature of the ejecta excavated by the impact, the recoil from which gave Dimorphos the biggest push. [...] "Before the impact, we were not really sure what to expect," said Cyrielle Opitom of the University of Edinburgh in an interview with Space.com.

Opitom led a team who used MUSE to go in search of any water on Dimorphos. They observed the Didymos-Dimorphos system on 11 occasions, from just before the impact to about a month afterwards. MUSE is able to split the light from the double-asteroid into a spectrum, or rainbow, of colors, to look for emission at specific wavelengths that corresponds to specific molecules. In particular, Opitom's team searched the ejecta for water molecules and for oxygen that could have come from the break-up of water molecules by the impact. However, no evidence of water was detected. Dimorphos, at least, seems to be a dry asteroid.

There was also no evidence in the ejecta of traces of the hydrazine fuel that was on board DART, nor the xenon from its ion engine, although given their small quantities the non-detection is not a surprise. However, MUSE's observations were able to track the evolution of the cloud of ejecta (debris) thrown up by the impact, and in particular they helped determine the size distribution of the dust particles initially in the ejecta cloud and later in the tail streaming away from the asteroid. The research was published in the journal Astronomy & Astrophysics.

Researchers have analyzed samples of the asteroid Ryugu collected by the Japanese Space Agency's Hayabusa2 spacecraft and found uracil, one of the informational units that make up RNA, the molecules that contain the instructions for how to build and operate living organisms. Nicotinic acid, also known as Vitamin B3 or niacin, which is an important cofactor for metabolism in living organisms, was also detected in the same samples. Phys.Org reports: This discovery by an international team, led by Associate Professor Yasuhiro Oba at Hokkaido University, adds to the evidence that important building blocks for life are created in space and could have been delivered to Earth by meteorites. The findings were published in the journal Nature Communications. The researchers extracted these molecules by soaking the Ryugu particles in hot water, followed by analyses using liquid chromatography coupled with high-resolution mass spectrometry. This revealed the presence of uracil and nicotinic acid, as well as other nitrogen-containing organic compounds. "We found uracil in the samples in small amounts, in the range of 6-32 parts per billion (ppb), while vitamin B3 was more abundant, in the range of 49-99 ppb," Oba elaborated. "Other biological molecules were found in the sample as well, including a selection of amino acids, amines and carboxylic acids, which are found in proteins and metabolism, respectively." The compounds detected are similar but not identical to those previously discovered in carbon-rich meteorites.

The team hypothesizes that the difference in concentrations in the two samples, collected from different locations on Ryugu, is likely due to the exposure to the extreme environments of space. They also hypothesized that the nitrogen-containing compounds were, at least in part, formed from the simpler molecules such as ammonia, formaldehyde and hydrogen cyanide. While these were not detected in the Ryugu samples, they are known to be present in cometary ice -- and Ryugu could have originated as a comet or another parent body that had been present in low temperature environments.

An anonymous reader quotes a report from The Guardian: The brew is so potent that practitioners report not only powerful hallucinations, but near-death experiences, contact with higher-dimensional beings, and life-transforming voyages through alternative realities. Often before throwing up, or having trouble at the other end. Now, scientists have gleaned deep insights of their own by monitoring the brain on DMT, or dimethyltryptamine, the psychedelic compound found in Psychotria viridis, the flowering shrub that is mashed up and boiled in the Amazonian drink, ayahuasca. The recordings reveal a profound impact across the brain, particularly in areas that are highly evolved in humans and instrumental in planning, language, memory, complex decision-making and imagination. The regions from which we conjure reality become hyperconnected, with communication more chaotic, fluid and flexible.

"At the dose we use, it is incredibly potent," said Robin Carhart-Harris, a professor of neurology and psychiatry at the University of California, San Francisco. "People describe leaving this world and breaking through into another that is incredibly immersive and richly complex, sometimes being populated by other beings that they feel might hold special power over them, like gods." He added: "What we have seen is that DMT breaks down the basic networks of the brain, causing them to become less distinct from each other. We also see the major rhythms of the brain -- that serve a largely inhibitory, constraining function -- break down, and in concert, brain activity becomes more entropic or information-rich."

For the latest study, Chris Timmermann, head of the DMT research group at Imperial College London, recruited 20 healthy volunteers who received a 20mg injection of DMT and a placebo on separate visits to the lab. All were screened to ensure they were physically and mentally suitable for the study. Using electroencephalography (EEG) and functional magnetic resonance imaging (fMRI), the scientists recorded the participants' brain activity before, during and after the drug took hold. The volunteers gave updates throughout on how intense the experience felt. None vomited as the emetic is another ingredient in ayahuasca. The results, published in the journal Proceedings of the National Academy of Sciences, provide the most advanced picture yet of the human brain on psychedelics. The recordings show how the brain's normal hierarchical organization breaks down, electrical activity becomes anarchic, and connectivity between regions soars, particularly those handling "higher level" functions such as imagination, which evolved most recently in humans. "The stronger the intensity of the experience, the more hyperconnected were those brain areas," said Timmermann. "We suspect that while the newer, more evolved aspects of the brain dysregulate under DMT, older systems in the brain may be disinhibited," said Carhart-Harris. "A similar kind of thing happens in dreaming. This is just the beginning in cracking the question of how DMT works to alter consciousness so dramatically."

Crippled by war and sanctions, Russia now faces evidence that its already-struggling space program is falling apart. In the past three months alone, Roscosmos has scrambled to resolve two alarming incidents. First, one of its formerly dependable Soyuz spacecraft sprang a coolant leak. Then the same thing happened on one of its Progress cargo ships. The civil space program's Soviet predecessor launched the first person into orbit, but with the International Space Station (ISS) nearing the end of its life, Russia's space agency is staring into the abyss.

"What we're seeing is the continuing demise of the Russian civil space program," says Bruce McClintock, a former defense attache at the US embassy in Moscow and current head of the Space Enterprise Initiative of the Rand Corporation, a nonprofit research organization. Around 10 years ago, Russian leaders chose to prioritize the country's military space program -- which focuses on satellite and anti-satellite technologies -- over its civilian one, McClintock says, and it shows.

Russia's space fleet is largely designed to be expendable. The history of its series of Soyuz rockets and crew capsules (they both have the same name) dates back to the Soviet era, though they've gone through upgrades since. Its Progress cargo vessels also launch atop Soyuz rockets. The cargo ships, crewed ships, and rockets are all single-use spacecraft. Anatoly Zak, creator and publisher of the independent publication RussianSpaceWeb, estimates that Roscosmos launches about two Soyuz vehicles per year, takes about 1.5 to 2 years to build each one, and doesn't keep a substantial standing fleet.

While Roscosmos officials did not respond to interview requests, the agency has been public about its recent technical issues.

Plus this, which failed to make headlines here: "For crewed launches, Russia has long depended on its Baikonur spaceport in neighboring Kazakhstan. But the nation has charged costly annual fees, and in March Kazakhstan seized Russian spaceport assets, reportedly due to Roscosmos' debt."

Longtime Slashdot reader drwho writes: A new type of propulsion system which uses no propellant, but rather only electricity, will be tested in a satellite to be launched from June 10's Falcon 9 launch. The IVO Quantum Drive utilizes an alternative theory of inertia known as "Quantum Inertia' by its originator Prof. Mike McCullough of U. Plymouth, which seeks to reconcile General Relativity (GR) with Quantum Field Theory (QFT). If successful, this would herald in a new era not only in satellite technology but in space travel as a whole. See this article for more details.

"Mysterious streaks of light were seen in the sky in the Sacramento area Friday night," reports the Associated Press.

The lights lasted about 40 seconds, remembered one witness who filmed the lights while enjoying a local brewery. The brewery then asked on Instagram if anyone could solve the mystery, the report continues: Jonathan McDowell says he can. McDowell is an astronomer at the Harvard-Smithsonian Center for Astrophysics. McDowell said Saturday in an interview with The Associated Press that he's 99.9% confident the streaks of light were from burning space debris.

McDowell said that a Japanese communications package that relayed information from the International Space Station to a communications satellite and then back to Earth became obsolete in 2017 when the satellite was retired. The equipment, weighing 310 kilograms (683 pounds), was jettisoned from the space station in 2020 because it was taking up valuable space and would burn up completely upon reentry, McDowell added....

He estimated the debris was about 40 miles high, going thousands of miles per hour. The U.S. Space Force confirmed the re-entry path over California for the Inter-Orbit Communication System, and the timing is consistent with what people saw in the sky, he added.

With all the space junk cluttering our orbits, Popular Science writes, "Lowering costs while also shortening satellite lifespans is important if space exploration and utilization is to remain safe and viable.

"As luck would have it, a group of students and researchers at Brown University just made promising headway for both issues." Last year, the team successfully launched their breadloaf-sized cube satellite (or cubesat) aboard a SpaceX Falcon 9 rocket for the comparatively low production cost of $10,000, with a dramatically shortened lifespan estimated at just five years. What's more, much of the microsat was constructed using accessible, off-the-shelf components, such as a popular $20 microprocessor powered by 48 AA batteries. In total, SBUDNIC — a play on Sputnik as well as an acronym of the students' names — is likely the first of its kind to be made almost entirely from materials not specifically designed for space travel.

Additionally, the group attached a 3D-printed drag sail made from Kapton film that unfurled once the cubesat reached orbit roughly 520 kilometers above Earth. Since tracking began in late May 2022, the students' satellite has already lowered down to 470 kilometers — well below its fellow rocketmates aboard the Falcon 9, which remain around 500 kilometers high.

Long-time Slashdot reader turp182 shares two stories about the new state-of-the-art in very-high-speed imaging. "The techniques don't image captured photons, but instead 'touch' the target to perform imaging/read structures using either lasers or neutrons."

First, Science Daily reports that physicists from the University of Gothenburg (with colleagues from the U.S. and Germany) have developed an ultrafast laser camera that can create videos at 12.5 billion images per second, "which is at least a thousand times faster than today's best laser equipment." [R]esearchers use a laser camera that photographs the material in [an ultrathin, one-atom-thick] two-dimensional layer.... By observing the sample from the side, it is possible to see what reactions and emissions occur over time and space. Researchers have used single-shot laser sheet compressed ultrafast photography to study the combustion of various hydrocarbons.... This has enabled researchers to illustrate combustion with a time resolution that has never been achieved before. "The more pictures taken, the more precisely we can follow the course of events...." says Yogeshwar Nath Mishra, who was one of the researchers at the University of Gothenburg and who is now presenting the results in a scientific article in the journal Light: Science & Applications.... The new laser camera takes a unique picture with a single laser pulse.
Meanwhile, ScienceAlert reports on a camera with a trillionth-of-a-second shutter speed — that is, 250 million times faster than digital cameras — that's actually able to photograph atomic activity, including "dynamic disorder." Simply put, dynamic disorder is when clusters of atoms move and dance around in a material in specific ways over a certain period — triggered by a vibration or a temperature change, for example. It's not a phenomenon that we fully understand yet, but it's crucial to the properties and reactions of materials. The new super-speedy shutter speed system gives us much more insight into what's happening....

The researchers are referring to their invention as variable shutter atomic pair distribution function, or vsPDF for short.... To achieve its astonishingly quick snap, vsPDF uses neutrons to measure the position of atoms, rather than conventional photography techniques. The way that neutrons hit and pass through a material can be tracked to measure the surrounding atoms, with changes in energy levels the equivalent of shutter speed adjustments.

Long-time Slashdot reader SpzToid quotes an intriguing new article from the Economist: Imagine a habitable colony on Mars or the Moon and the kinds of structures that come to mind are probably gleaming domes or shiny metallic tubes snaking over the surface. But with no Earth-like atmosphere or magnetic field to repel solar radiation and micrometeorites, space colonists would probably need to pile metres-thick rocks and geological rubble onto the roofs of such off-world settlements. More like a hobbit hole than Moonbase Alpha.

There could be another solution, however, that would offer future colonists safer and far more expansive living space than any cramped base built on the surface. Writing in Acta Astronautica, Raymond Martin, an engineer at Blue Origin, a rocket company, and Haym Benaroya, an aerospace engineer at Rutgers University, explore the benefits of setting up a Moon base inside giant geological tunnels that lie just below the lunar surface.

First discovered during the Apollo programme, these lunar lava tubes are a legacy of when Earth's nearest celestial neighbour was geologically hyperactive, with streams of boiling basaltic magma bursting from the interior to flow across the Moon's surface as lava. Found on Earth (see picture), and identified on Mars, lava tubes form when the sluggish top layer of a lava stream slows and cools, forming a thick and rocky lid that is left behind when the rest of the lava underneath eventually drains away.

Lava tubes on Earth are usually up to 15 metres wide and can run for several kilometres. But the reduced gravity on the Moon makes them hundreds of times bigger, creating colossal cave systems that are up to a kilometre across and hundreds of kilometres long.

RockDoctor (Slashdot reader #15,477) writes: A recent paper on ArXiv reports new spectroscopic analyses of the surfaces of 42 asteroids. The main result for space enthusiasts is that there is not one "M" class asteroid (metal-rich) surface in the collection.

The imagery that (many) people grow up with from Hollywood and TV "science" "documentaries" is that the Solar system is full of asteroids which are made of metal ready for mining to produce solid ingots of precious metals. That's Hollywood, not reality. This result is about what you'd expect from the proportion of metallic asteroids — otherwise estimated at about 0.5% of the population.

The asteroid mining fraternity dream of taking apart an M-type asteroid like Psyche, which is fair enough as a dream. Even as a dream for "asteroid mining" metal market speculators. But they are relatively rare asteroids. A realistic "ISRU" (In-Situ Resource Utilisation) plan is going to have to expect to digest around 200 silicate mineral (and clay ("phyllosilicate"), and ice) asteroids for every metallic one they digest.
Here's the home page for the project.

"The World Health Organization on Friday called on China to release new data linking the Covid pandemic's origins to animal samples at Wuhan Market after the country recently took down the research," reports CNBC.

The existence of the new data was revealed by the Atlantic earlier this week, in an article reporting that the newly-discovered samples showed the virus was present in creatures for sale there near the very beginning of the pandemic: A new analysis of genetic sequences collected from the market shows that raccoon dogs being illegally sold at the venue could have been carrying and possibly shedding the virus at the end of 2019. It's some of the strongest support yet, experts told me, that the pandemic began when SARS-CoV-2 hopped from animals into humans, rather than in an accident among scientists experimenting with viruses....

The genetic sequences were pulled out of swabs taken in and near market stalls around the pandemic's start. They represent the first bits of raw data that researchers outside of China's academic institutions and their direct collaborators have had access to. A few weeks ago, the data appeared on an open-access genomic database called GISAID, after being quietly posted by researchers affiliated with the country's Center for Disease Control and Prevention. By almost pure happenstance, scientists in Europe, North America, and Australia spotted the sequences, downloaded them, and began an analysis.

The samples were already known to be positive for the coronavirus, and had been scrutinized before by the same group of Chinese researchers who uploaded the data to GISAID. But that prior analysis, released as a preprint publication in February 2022, asserted that "no animal host of SARS-CoV-2 can be deduced...." The new analysis, led by Kristian Andersen, Edward Holmes, and Michael Worobey — three prominent researchers who have been looking into the virus's roots — shows that that may not be the case. Within about half a day of downloading the data from GISAID, the trio and their collaborators discovered that several market samples that tested positive for SARS-CoV-2 were also coming back chock-full of animal genetic material — much of which was a match for the common raccoon dog. Because of how the samples were gathered, and because viruses can't persist by themselves in the environment, the scientists think that their findings could indicate the presence of a coronavirus-infected raccoon dog in the spots where the swabs were taken....

The new analysis builds on extensive previous research that points to the market as the source of the earliest major outbreak of SARS-CoV-2: Many of the earliest known COVID-19 cases of the pandemic were clustered roughly in the market's vicinity. And the virus's genetic material was found in many samples swabbed from carts and animal-processing equipment at the venue, as well as parts of nearby infrastructure, such as storehouses, sewage wells, and water drains. Raccoon dogs, creatures commonly bred for sale in China, are also already known to be one of many mammal species that can easily catch and spread the coronavirus. All of this left one main hole in the puzzle to fill: clear-cut evidence that raccoon dogs and the virus were in the exact same spot at the market, close enough that the creatures might have been infected and, possibly, infectious.

That's what the new analysis provides. Think of it as finding the DNA of an investigation's main suspect at the scene of the crime.
The article also notes that the genetic sequences "also vanished from the database shortly after the international team of researchers notified the Chinese researchers of their preliminary findings, without explanation." And it adds that all along China has "vehemently" fought the theory that Covid-19 originated from live animals being sold at Wuhan market. Although "in June 2021, a team of researchers published a study documenting tens of thousands of mammals for sale in wet markets in Wuhan between 2017 and late 2019, including at Huanan."

"The animals were kept in largely illegal, cramped, and unhygienic settings — conditions conducive to viral transmission — and among them were more than 1,000 raccoon dogs." And there's even photos of raccoon dogs for sale at the market in December of 2019.


More coverage of the newly-discovered data is now appearing in numerous news outlets, including the New York Times, NBC News, ABC News, the Guardian, PBS, and Science.
