World's First Bioprocessor Uses 16 Human Brain Organoids, Consumes Less Power (tomshardware.com) 2

"A Swiss biocomputing startup has launched an online platform that provides remote access to 16 human brain organoids," reports Tom's Hardware: FinalSpark claims its Neuroplatform is the world's first online platform delivering access to biological neurons in vitro. Moreover, bioprocessors like this "consume a million times less power than traditional digital processors," the company says. FinalSpark says its Neuroplatform is capable of learning and processing information, and due to its low power consumption, it could reduce the environmental impacts of computing. In a recent research paper about its developments, FinalSpakr claims that training a single LLM like GPT-3 required approximately 10GWh — about 6,000 times greater energy consumption than the average European citizen uses in a whole year. Such energy expenditure could be massively cut following the successful deployment of bioprocessors.

The operation of the Neuroplatform currently relies on an architecture that can be classified as wetware: the mixing of hardware, software, and biology. The main innovation delivered by the Neuroplatform is through the use of four Multi-Electrode Arrays (MEAs) housing the living tissue — organoids, which are 3D cell masses of brain tissue...interfaced by eight electrodes used for both stimulation and recording... FinalSpark has given access to its remote computing platform to nine institutions to help spur bioprocessing research and development. With such institutions' collaboration, it hopes to create the world's first living processor.

FinalSpark was founded in 2014, according to Wikipedia's page on wetware computing. "While a wetware computer is still largely conceptual, there has been limited success with construction and prototyping, which has acted as a proof of the concept's realistic application to computing in the future."

'Planetary Parade' Will See Six Planets Line Up In the Morning Sky (astronomy.com) 25

On June 3, a "planet parade" of six planets -- Jupiter, Mercury, Uranus, Mars, Neptune and Saturn -- will form a straight line through the pre-dawn sky. Astronomy.com reports: Some 20 minutes before sunrise, all six planets should be visible, though note that Uranus (magnitude 5.9) and Neptune (magnitude 7.8) will be too faint for naked-eye observing and, although they're present in the lineup, will need binoculars or a telescope to spot. But Jupiter (magnitude -2), Mercury (magnitude -1), Mars (magnitude 1), and Saturn (magnitude 1) will all stand out clearly to the naked eye in a line spanning some 73 degrees on the sky.

What's more, a delicate waning crescent Moon is crashing the party as well, standing just to the lower left of Mars. Note, however, that our Moon is not perfectly in line -- that's because Luna's orbit is tilted some 5 degrees with respect to the ecliptic. The next morning, June 4, the crescent Moon does a little better, falling more closely in line a bit farther from Mars. But now Mercury has stepped out of place and stands to Jupiter's lower right (south) as the two planets reach a close conjunction just 7 degrees apart -- not to be missed, especially in binoculars or telescopes!

By June 5, Mercury lies to Jupiter's lower left, replacing the gas giant as the easternmost point in the planetary lineup. And the nearly New Moon (just 2 percent lit) stands above the pair. As June progresses, Mercury quickly ducks out of view, passing close to the Sun before reappearing in the evening sky and leaving us with only five planets in the pre-dawn sky. But those planets continue to form a nice, clean line, stretching nearly 80 degrees from Jupiter to Saturn (with Uranus, Mars, and Neptune in between) by June 30. On this morning, the Moon as rejoined the line, once again a delicate waning crescent about 33 percent lit, hanging perfectly in place to Mars' upper right.

Scientists Find the Largest Known Genome Inside a Small Plant (nytimes.com) 21

An anonymous reader quotes a report from the New York Times: Last year, Jaume Pellicer led a team of fellow scientists into a forest on Grande Terre, an island east of Australia. They were in search of a fern called Tmesipteris oblanceolata. Standing just a few inches tall, it was not easy to find on the forest floor. "It doesn't catch the eye," said Dr. Pellicer, who works at the Botanical Institute of Barcelona in Spain. "You would probably step on it and not even realize it." The scientists eventually managed to spot the nondescript fern. When Dr. Pellicer and his colleagues studied it in the lab, they discovered it held an extraordinary secret. Tmesipteris oblanceolata has the largest known genome on Earth. As the researchers described in a study published on Friday, the fern's cells contain more than 50 times as much DNA as ours do. [The analysis revealed the species T. oblanceolata to have a record-breaking genome size of 160.45 Gbp, which is about 7% larger than that of P. japonica (148.89 Gbp). For comparison, the human genome contains about 3.1 Gbp distributed across 23 chromosomes and when stretched out like a ball of yarn, the length of DNA in each cell only measures about 2m.] "Surprisingly, having a larger genome is usually not an advantage," notes Phys.org in a report. "In the case of plants, species possessing large amounts of DNA are restricted to being slow growing perennials, are less efficient at photosynthesis (the process by which plants convert the sun's energy into sugars) and require more nutrients (especially nitrogen and phosphates) to grow and compete successfully with their smaller-genomed neighbors. In turn, such effects may influence the ability of a plant to adapt to climate change and their risk of extinction."

"In animals, some of the largest genomes include the marbled lungfish (Protopterus aethiopicus) at 129.90 Gbp and the Neuse River waterdog (Necturus lewisi) at 117.47 Gbp," reports Phys.org. "In stark contrast, six of the largest-known eukaryotic genomes are held by plants, including the European mistletoe (Viscum album) at 100.84 Gbp."

Biomedical Paper Retractions Have Quadrupled in 20 Years (nature.com) 24

The retraction rate for European biomedical-science papers increased fourfold between 2000 and 2021, a study of thousands of retractions has found. Nature: Two-thirds of these papers were withdrawn for reasons relating to research misconduct, such as data and image manipulation or authorship fraud. These factors accounted for an increasing proportion of retractions over the roughly 20-year period, the analysis suggests. "Our findings indicate that research misconduct has become more prevalent in Europe over the last two decades," write the authors, led by Alberto RuanoâRavina, a public-health researcher at the University of Santiago de Compostela in Spain.

Other research-integrity specialists point out that retractions could be on the rise because researchers and publishers are getting better at investigating and identifying potential misconduct. There are more people working to spot errors and new digital tools to screen publications for suspicious text or data. Scholarly publishers have faced increased pressure to clear up the literature in recent years as sleuths have exposed cases of research fraud, identified when peer review has been compromised and uncovered the buying and selling of research articles. Last year saw a record 10,000 papers retracted. Although misconduct is a leading cause of retractions, it is not always responsible: some papers are retracted when authors discover honest errors in their work.

Japan's Push To Make All Research Open Access is Taking Shape (nature.com) 6

The Japanese government is pushing ahead with a plan to make Japan's publicly funded research output free to read. From a report: In June, the science ministry will assign funding to universities to build the infrastructure needed to make research papers free to read on a national scale. The move follows the ministry's announcement in February that researchers who receive government funding will be required to make their papers freely available to read on the institutional repositories from January 2025. The Japanese plan "is expected to enhance the long-term traceability of research information, facilitate secondary research and promote collaboration," says Kazuki Ide, a health-sciences and public-policy scholar at Osaka University in Suita, Japan, who has written about open access in Japan.

The nation is one of the first Asian countries to make notable advances towards making more research open access (OA) and among the first countries in the world to forge a nationwide plan for OA. The plan follows in the footsteps of the influential Plan S, introduced six years ago by a group of research funders in the United States and Europe known as cOAlition S, to accelerate the move to OA publishing. The United States also implemented an OA mandate in 2022 that requires all research funded by US taxpayers to be freely available from 2026. When the Ministry of Education, Culture, Sports, Science and Technology (MEXT) announced Japan's pivot to OA in February, it also said that it would invest around $63 million to standardize institutional repositories -- websites dedicated to hosting scientific papers, their underlying data and other materials -- ensuring that there will be a mechanism for making research in Japan open.

Alzheimer's Takes a Financial Toll Long Before Diagnosis, Study Finds (nytimes.com) 43

Long before people develop dementia, they often begin falling behind on mortgage payments, credit card bills and other financial obligations, new research shows. The New York Times: A team of economists and medical experts at the Federal Reserve Bank of New York and Georgetown University combined Medicare records with data from Equifax, the credit bureau, to study how people's borrowing behavior changed [PDF] in the years before and after a diagnosis of Alzheimer's or a similar disorder. What they found was striking: Credit scores among people who later develop dementia begin falling sharply long before their disease is formally identified. A year before diagnosis, these people were 17.2 percent more likely to be delinquent on their mortgage payments than before the onset of the disease, and 34.3 percent more likely to be delinquent on their credit card bills. The issues start even earlier: The study finds evidence of people falling behind on their debts five years before diagnosis.

"The results are striking in both their clarity and their consistency," said Carole Roan Gresenz, a Georgetown University economist who was one of the study's authors. Credit scores and delinquencies, she said, "consistently worsen over time as diagnosis approaches, and so it literally mirrors the changes in cognitive decline that we're observing." The research adds to a growing body of work documenting what many Alzheimer's patients and their families already know: Decision-making, including on financial matters, can begin to deteriorate long before a diagnosis is made or even suspected. People who are starting to experience cognitive decline may miss payments, make impulsive purchases or put money into risky investments they would not have considered before the disease.

You Can Thank Private Equity for That Enormous Doctor's Bill 95

Private-equity investors have poured billions into healthcare but often game the system, hurting both doctors and patients. From a report: Consolidation is as American as apple pie. When a business gets bigger, it forces mom-and-pop players out of the market, but it can boost profits and bring down costs, too. Think about the pros and cons of Walmart and "Every Day Low Prices." In a complex, multitrillion-dollar system like America's healthcare market, though, that principle has turned into a harmful arms race that has helped drive prices increasingly higher without improving care. Years of dealmaking has led to sprawling hospital systems, vertically integrated health insurance companies, and highly concentrated private equity-owned practices resulting in diminished competition and even the closure of vital health facilities. As this three-part Heard on the Street series will show, the rich rewards and lax oversight ultimately create pain for both patients and the doctors who treat them. Belatedly, state and federal regulators and lawmakers are zeroing in on consolidation, creating uncertainty for the investors who have long profited from the healthcare merger boom.

Consider the impact of massive private-equity investment in medical practices. When a patient with employer-based insurance goes under for surgery, the anesthesiologist's fee is supposed to be determined by market forces. But what happens if one firm quietly buys out several anesthesiologists in the same city and then hikes the price of the procedure? Such a scheme was allegedly implemented by the private-equity firm Welsh, Carson, Anderson & Stowe and the company it created in 2012, U.S. Anesthesia Partners, according to a Federal Trade Commission lawsuit filed last year. It started by buying the largest practice in Houston and then making three further acquisitions, eventually expanding into other cities throughout the state of Texas. In each location, the lawsuit alleges, USAP pursued an aggressive strategy of eliminating competitors by either acquiring them or conspiring with them to weaken competition. As one insurance executive put it in the FTC lawsuit, USAP and Welsh Carson used acquisitions to "take the highest rate of all ... and then peanut butter spread that across the entire state of Texas." In May, U.S. District Judge Kenneth Hoyt dismissed the FTC's unusual step of charging the private-equity investor, Welsh Carson, but allowed the case against USAP to proceed.

NASA's James Webb Space Telescope Finds Most Distant Known Galaxy (nasa.gov) 40

With the help of NASA's James Webb Space Telescope (JWST), an international team of astronomers discovered a galaxy at a redshift of 14.32, indicating it existed just 290 million years post-Big Bang. In a NASA release today, Stefano Carniani from Scuola Normale Superiore in Pisa, Italy, and Kevin Hainline from the University of Arizona in Tucson, Arizona, described how this source was found and what its unique properties tell us about galaxy formation: "The instruments on Webb were designed to find and understand the earliest galaxies, and in the first year of observations as part of the JWST Advanced Deep Extragalactic Survey (JADES), we found many hundreds of candidate galaxies from the first 650 million years after the big bang. In early 2023, we discovered a galaxy in our data that had strong evidence of being above a redshift of 14, which was very exciting, but there were some properties of the source that made us wary. The source was surprisingly bright, which we wouldn't expect for such a distant galaxy, and it was very close to another galaxy such that the two appeared to be part of one larger object. When we observed the source again in October 2023 as part of the JADES Origins Field, new imaging data obtained with Webb's narrower NIRCam (Near-Infrared Camera) filters pointed even more toward the high-redshift hypothesis. We knew we needed a spectrum, as whatever we would learn would be of immense scientific importance, either as a new milestone in Webb's investigation of the early universe or as a confounding oddball of a middle-aged galaxy.

In January 2024, NIRSpec observed this galaxy, JADES-GS-z14-0, for almost ten hours, and when the spectrum was first processed, there was unambiguous evidence that the galaxy was indeed at a redshift of 14.32, shattering the previous most-distant galaxy record (z = 13.2 of JADES-GS-z13-0). Seeing this spectrum was incredibly exciting for the whole team, given the mystery surrounding the source. This discovery was not just a new distance record for our team; the most important aspect of JADES-GS-z14-0 was that at this distance, we know that this galaxy must be intrinsically very luminous. From the images, the source is found to be over 1,600-light years across, proving that the light we see is coming mostly from young stars and not from emission near a growing supermassive black hole. This much starlight implies that the galaxy is several hundreds of millions of times the mass of the Sun! This raises the question: How can nature make such a bright, massive, and large galaxy in less than 300 million years?

The data reveal other important aspects of this astonishing galaxy. We see that the color of the galaxy is not as blue as it could be, indicating that some of the light is reddened by dust, even at these very early times. JADES researcher Jake Helton of Steward Observatory and the University of Arizona also identified that JADES-GS-z14-0 was detected at longer wavelengths with Webb's MIRI (Mid-Infrared Instrument), a remarkable achievement considering its distance. The MIRI observation covers wavelengths of light that were emitted in the visible-light range, which are redshifted out of reach for Webb's near-infrared instruments. Jake's analysis indicates that the brightness of the source implied by the MIRI observation is above what would be extrapolated from the measurements by the other Webb instruments, indicating the presence of strong ionized gas emission in the galaxy in the form of bright emission lines from hydrogen and oxygen. The presence of oxygen so early in the life of this galaxy is a surprise and suggests that multiple generations of very massive stars had already lived their lives before we observed the galaxy.

All of these observations, together, tell us that JADES-GS-z14-0 is not like the types of galaxies that have been predicted by theoretical models and computer simulations to exist in the very early universe. Given the observed brightness of the source, we can forecast how it might grow over cosmic time, and so far we have not found any suitable analogs from the hundreds of other galaxies we've observed at high redshift in our survey. Given the relatively small region of the sky that we searched to find JADES-GS-z14-0, its discovery has profound implications for the predicted number of bright galaxies we see in the early universe, as discussed in another concurrent JADES study (Robertson et al., recently accepted). It is likely that astronomers will find many such luminous galaxies, possibly at even earlier times, over the next decade with Webb. We're thrilled to see the extraordinary diversity of galaxies that existed at Cosmic Dawn!

AST SpaceMobile Stock Surges 69% After Verizon Satellite Internet Deal (cnbc.com) 2

Satellite-to-phones service provider AST SpaceMobile announced a deal with Verizon to provide remote coverage across the United States. "Verizon's deal effectively includes a $100 million raise for AST, as well, in the form of $65 million in commercial service prepayments and $35 million in debt via convertible notes," reports CNBC. "The companies said that $45 million of the prepayments 'are subject to certain conditions' such as needed regulatory approvals and signing of a definitive commercial agreement." Shares of AST jumped 69% in trading to close at $9.02 a share -- the largest single day rise for the company's stock since it went public in 2021. From the report: AST SpaceMobile is building satellites to provide broadband service to unmodified smartphones, in the nascent "direct-to-device" communications market. [...] The Verizon partnership follows a similar pattern to AT&T's work with AST. Back in January, AT&T was a co-debt investor in the company alongside Google and Vodafone. The companies then established the commercial agreement earlier this month, which "lays out in much more detail how we will ultimately offer service together," AST's Chief Strategy Officer Scott Wisniewski said in a statement to CNBC. [...] AST expects to launch its first five commercial satellites later this year.

Earthcare Cloud Mission Launches To Resolve Climate Unknowns (bbc.com) 25

An anonymous reader quotes a report from the BBC: A sophisticated joint European-Japanese satellite has launched to measure how clouds influence the climate. Some low-level clouds are known to cool the planet, others at high altitude will act as a blanket. The Earthcare mission will use a laser and a radar to probe the atmosphere to see precisely where the balance lies. It's one of the great uncertainties in the computer models used to forecast how the climate will respond to increasing levels of greenhouse gases. "Many of our models suggest cloud cover will go down in the future and that means that clouds will reflect less sunlight back to space, more will be absorbed at the surface and that will act as an amplifier to the warming we would get from carbon dioxide," Dr Robin Hogan, from the European Centre for Medium-Range Weather Forecasts, told BBC News.

The 2.3-tonne satellite was sent up from California on a SpaceX rocket. The project is led by the European Space Agency (ESA), which has described it as the organization's most complex Earth observation venture to date. Certainly, the technical challenge in getting the instruments to work as intended has been immense. It's taken fully 20 years to go from mission approval to launch. Earthcare will circle the Earth at a height of about 400km (250 miles). It's actually got four instruments in total that will work in unison to get at the information sought by climate scientists.

The simplest is an imager -- a camera that will take pictures of the scene passing below the spacecraft to give context to the measurements made by the other three instruments. Earthcare's European ultraviolet laser will see the thin, high clouds and the tops of clouds lower down. It will also detect the small particles and droplets (aerosols) in the atmosphere that influence the formation and behavior of clouds. The Japanese radar will look into the clouds, to determine how much water they are carrying and how that's precipitating as rain, hail and snow. And a radiometer will sense how much of the energy falling on to Earth from the Sun is being reflected or radiated back into space.

Rivers of Lava on Venus Reveal a More Volcanically Active Planet (nytimes.com) 24

Witnessing the blood-red fires of a volcanic eruption on Earth is memorable. But to see molten rock bleed out of a volcano on a different planet would be extraordinary. That is close to what scientists have spotted on Venus: two vast, sinuous lava flows oozing from two different corners of Earth's planetary neighbor. From a report: "After you see something like this, the first reaction is 'wow,'" said Davide Sulcanese, a doctoral student at the Universita d'Annunzio in Pescara, Italy, and an author of a study reporting the discovery in the journal Nature Astronomy, published on Monday. Earth and Venus were forged at the same time. Both are made of the same primeval matter, and both are the same age and size. So why is Earth a paradise overflowing with water and life, while Venus is a scorched hellscape with acidic skies?

Volcanic eruptions tinker with planetary atmospheres. One theory holds that, eons ago, several apocalyptic eruptions set off a runaway greenhouse effect on Venus, turning it from a temperate, waterlogged world into an arid desert of burned glass. To better understand its volcanism, scientists hoped to catch a Venusian eruption in the act. But although the planet is known to be smothered in volcanoes, an opaque atmosphere has prevented anyone from seeing an eruption the way spacecraft have spotted them on Io, the hypervolcanic moon of Jupiter. In the 1990s, NASA's spacecraft Magellan used cloud-penetrating radar to survey most of the planet. But back then, the relatively low-resolution images made spotting fresh molten rock a troublesome task.

Ditch Brightly Colored Plastic, Anti-Waste Researchers Tell Firms 82

Retailers are being urged to stop making everyday products such as drinks bottles, outdoor furniture and toys out of brightly coloured plastic after researchers found it degrades into microplastics faster than plainer colours. From a report: Red, blue and green plastic became "very brittle and fragmented," while black, white and silver samples were "largely unaffected" over a three-year period, according to the findings of the University of Leicester-led project. The scale of environmental pollution caused by plastic waste means that microplastics, or tiny plastic particles, are everywhere. Indeed, they were recently found in human testicles, with scientists suggesting a possible link to declining sperm counts in men.

In this case, scientists from the UK and the University of Cape Town in South Africa used complementary studies to show that plastics of the same composition degrade at different rates depending on the colour. The UK researchers put bottle lids of various colours on the roof of a university building to be exposed to the sun and the elements for three years. The South African study used plastic items found on a remote beach. "It's amazing that samples left to weather on a rooftop in Leicester and those collected on a windswept beach at the southern tip of the African continent show similar results," said Dr Sarah Key, who led the project. "What the experiments showed is that even in a relatively cool and cloudy environment for only three years, huge differences can be seen in the formation of microplastics." This field study, published in the journal Environmental Pollution, is the first such proof of this effect. It suggests that retailers and manufacturers should give more consideration to the colour of short-lived plastics.

North Korea Says Its Attempt To Put Another Spy Satellite Into Orbit Has Failed (yahoo.com) 20

A North Korean rocket carrying its second spy satellite exploded midair on Monday, state media reported, after its neighbors strongly rebuked its planned launch. From a report: The North's official Korean Central News Agency said it launched a spy satellite aboard a new rocket at its main northwestern space center. But KCNA said the rocket blew up during a first-stage flight soon after liftoff due to a suspected engine problem. Earlier Monday, North Korea had notified Japan's coast guard about its plans to launch "a satellite rocket," with a warning to exercise caution in the waters between the Korean Peninsula and China and east of the main Philippine island of Luzon during a launch window from Monday through June 3.

South Korea's Joint Chiefs of Staff later said it detected a launch trajectory believed to be of a spy satellite fired from the North's main space center at 10:44 p.m. on Monday. Four minutes later, many fragments were spotted in the waters, it said. Japanese Prime Minister's Office earlier issued a missile alert for the island of Okinawa following North Korea's launch. The alert was lifted soon after. Japan's NHK public television earlier reported that an image captured by a camera in northeastern China showed an orange light in the sky and then an apparent explosion a moment later.

Food Industry Launches 'Ferocious' Campaign Against Regulations on Ultraprocessed Foods (arstechnica.com) 208

Studies show ultraprocessed food "encourages overeating but may leave the eater undernourished," writes Ars Technica.

But the food industry's response has been "a ferocious campaign against regulation." In part it has used the same lobbying playbook as its fight against labeling and taxation of "junk food" high in calories: big spending to influence policymakers. FT analysis of US lobbying data from non-profit Open Secrets found that food and soft drinks-related companies spent $106 million on lobbying in 2023, almost twice as much as the tobacco and alcohol industries combined. Last year's spend was 21 percent higher than in 2020, with the increase driven largely by lobbying relating to food processing as well as sugar.

In an echo of tactics employed by cigarette companies, the food industry has also attempted to stave off regulation by casting doubt on the research of scientists like [Brazilian nutritional scientist Carlos] Monteiro. "The strategy I see the food industry using is deny, denounce, and delay," says Barry Smith, director of the Institute of Philosophy at the University of London and a consultant for companies on the multisensory experience of food and drink.

So far the strategy has proved successful. Just a handful of countries, including Belgium, Israel, and Brazil, currently refer to UPFs in their dietary guidelines. But as the weight of evidence about UPFs grows, public health experts say the only question now is how, if at all, it is translated into regulation. "There's scientific agreement on the science," says Jean Adams, professor of dietary public health at the MRC Epidemiology Unit at the University of Cambridge. "It's how to interpret that to make a policy that people aren't sure of."

[...] As researchers have learned more about the link between UPFs and poor health outcomes, companies have remained largely silent about these risks, leaving trade bodies that advocate on their behalf to argue loudly against the validity of the research.

1 in 9 American Kids Were Diagnosed With ADHD, New Study Finds (npr.org) 175

"About 1 in 9 children in the U.S., between the ages of 3 and 17, have been diagnosed with ADHD," reports NPR: That's according to a new report from the Centers for Disease Control and Prevention that calls attention-deficit/hyperactivity disorder an "expanding public health concern."

Researchers found that in 2022, 7.1 million kids and adolescents in the U.S. had received an ADHD diagnosis — a million more children than in 2016. That jump in diagnoses was not surprising, given that the data was collected during the pandemic, says Melissa Danielson, a statistician with the CDC's National Center on Birth Defects and Developmental Disabilities and the study's lead author. She notes that other studies have found that many children experienced heightened stress, depression and anxiety during the pandemic. "A lot of those diagnoses... might have been the result of a child being assessed for a different diagnosis, something like anxiety or depression, and their clinician identifying that the child also had ADHD," Danielson says. The increase in diagnoses also comes amid growing awareness of ADHD — and the different ways that it can manifest in children...

The study, which appears in the Journal of Clinical Child & Adolescent Psychology, was based on data from the National Survey of Children's Health, which gathers detailed information from parents.
