An influential thinktank that has led the backlash against the government's net zero policy has received funding from groups with oil and gas interests, according to tax documents seen by the Guardian and OpenDemocracy. From a report: Though the Global Warming Policy Foundation (GWPF) has always said it is independent of the fossil fuel industry, the revelations about its funding will raise questions over its campaigning. The thinktank has always refused to disclose its donors, but tax documents filed with US authorities reveal that one of its donors has $30m of shares in 22 companies working in coal, oil and gas. Over four years the GWPF's US arm, the American Friends of the GWPF, received more than $1m from US donors. The vast majority of this, $864,884, was channelled to the UK group, with some being held back for expenses.

Of the $1.8m the GWPF has received in charitable donations since 2017, about 45% has come from the US. It received $210,525 in 2018 and 2020 from the Sarah Scaife Foundation -- set up by the billionaire libertarian heir to an oil and banking dynasty. The US-based foundation has $30m-worth of shares in 22 energy companies including $9m in Exxon and $5.7m in Chevron, according to its financial filings. Between 2016 and 2020, the American Friends of the GWPF received $620,259 from the Donors Trust, which is funded by the Koch brothers, who inherited their father's oil empire and have spent hundreds of millions of dollars funding the climate denial movement. "It is disturbing that the Global Warming Policy Foundation is acting as a channel through which American ideological groups are trying to interfere in British democracy," said Bob Ward, policy and communications director at the LSE Grantham Research Institute on Climate Change and the Environment.

NBC News is reporting that the United States has officially surpassed 1 million COVID-19 deaths -- "a once unthinkable scale of loss even for the country with the world's highest recorded toll from the virus." From the report: The number -- equivalent to the population of San Jose, California, the 10th largest city in the U.S. -- was reached at stunning speed: 27 months after the country confirmed its first case of the virus. While deaths from Covid have slowed in recent weeks, about 360 people have still been dying every day. The casualty count is far higher than what most people could have imagined in the early days of the pandemic [...].

Now, more than two years and 999,999 fatalities later, the U.S. death toll is the world's highest total by a significant margin, figures show. In a distant second is Brazil, which has recorded just over 660,000 confirmed Covid deaths.

Researchers at the Terasaki Institute have now shown that silk scaffolds loaded with stem cells can help tendons regenerate more effectively. New Atlas reports: For the new study, the Terasaki researchers developed their own scaffold that could support the tendon while it healed. This scaffold was made of silk fibroin paired with a hydrogel known as GelMA -- the former gave the scaffold strength and stretchability, while the latter is biocompatible and encourages cells to attach and grow. After experimenting to get the right ratios of ingredients, the team fabricated nanofiber sheets of their silk fibroin and GelMA (SG) material. Then the sheets are seeded with mesenchymal stem cells (MSCs), which can not only differentiate into several cell types, but also aid regeneration by producing signaling molecules that summon immune cells to the area and encourage new blood vessels to form.

The team tested these stem-cell-loaded SG sheets in rats with injuries to their Achilles tendons. Compared to other scaffolds loaded with stem cells, those made of SG healed the tendons the fastest, while also forming densely packed tendon fibers, reducing injury sites, and remodeling the muscle components. "The synergistic effects of GelMA's capacity for supporting regenerative tissue formation and the structural advantages of silk fibroin make our composite material well suited for tendon repair," said HanJun Kim, lead researcher on the study. The team hopes that with further work, the stem-cell-loaded scaffolds could eventually lead to new therapies for tendon injuries. The research has been published in the journal Small.

technology_dude shares a report from Ars Technica: As part of its Artemis program to return humans to the Moon this decade, NASA has a minimum requirement that its "human landing system" must be able to deliver 865 kg to the lunar surface. This is based on the mass of two crew members and their equipment needed for a short stay. However, in selecting SpaceX's Starship vehicle to serve as its human lander, NASA has chosen a system with a lot more capability. Starship will, in fact, be able to deliver 100 metric tons to the surface of the Moon -- more than 100 times NASA's baseline goal.

"Starship can land 100 tons on the lunar surface," said Aarti Matthews, Starship Human Landing System program manager for SpaceX. "And it's really hard to think about what that means in a tangible way. One hundred tons is four fire trucks. It's 100 Moon rovers. My favorite way to explain this to my kids is that it's the weight of more than 11 elephants." Matthews made her comments last week at the ASCENDxTexas space conference in Houston. She was responding to a question from an audience member, Jeff Michel, an engineer at Johnson Space Center. [...] "NASA specified a high-level need, but we, industry, are taking away one of your biggest constraints that you have in designing your payloads and your systems," she said. "It's significantly higher mass. It's essentially infinite volume for the purposes of this conversation. And the cost is an order of magnitude lower. I think that our NASA community, our payload community, should really think about this new capability that's coming online."

"We all need to be thinking bigger and better and really inspirationally about what we can do," Matthews said. "Anyone who has worked on hardware design for space application knows you're fighting for kilograms, and sometimes you're fighting for grams, and that takes up so much time and energy. It really limits ultimately what your system can do. That's gone away entirely." [...] "If you, as an engineer, are developing an in-situ resource utilization system, what does your system look like when you have no mass constraint?" she asked. "What about when you have no volume constraint? That would be the exciting thing that I would like to hear from NASA engineers, what they can do with this capability." "The engineer says NASA is not thinking big enough," adds Slashdot reader technology_dude. "I think it's pretty obvious what the payload should be, a nuclear powered boring machine. With flamethrower weapons just in case! Leave a comment for my resume. Maybe I'll call."

An anonymous reader quotes a report from Gizmodo: Helga and Zohar are headed for a trip around the Moon on an important mission, measuring radiation risks for female astronauts for the first time. The inanimate pair are manikins modeled after the body of an adult woman. For the Artemis 1 mission, in which an uncrewed Orion capsule will travel to the Moon and back, one of the manikins will be outfitted with a newly developed radiation protection vest. Helga and Zohar, as they're called, won't be alone, as they'll be joined by a third manikin that will collect data about flight accelerations and vibrations. Artemis 1 is scheduled to blast off later this year. The Artemis program aims to return humans to the Moon for the first time in over 50 years, but this time the space agency has vowed to land the first woman on the dusty lunar surface. [...]

The Helga and Zohar manikins are part of the MARE experiment, designed by the German Aerospace Center (DLR). The experiment will use two identical representations of the female body to investigate radiation exposure throughout the flight of the Artemis 1 mission, which may last up to six weeks. Artemis 1 will set the stage for Artemis 2, in which an Orion capsule carrying real humans will fly to the Moon and back (without landing), possibly as early as 2024. [...] Here's how it will work. The manikins are made from materials that mimic the bones, soft tissues, and organs of an adult woman, all of which will be tracked by more than 10,000 passive sensors and 34 active radiation detectors, according to DLR. One of the manikins, Helga, will fly to the Moon unprotected while the other one, Zohar, will wear a radiation protection vest called the AstroRad (which was developed by American aerospace company Lockheed Martin and Israeli startup StemRad).

As they travel aboard the Orion spacecraft to the Moon, Helga and Zohar will be affected by the harsh environment of space. The manikins, having traveled beyond the protective shielding of Earth's magnetosphere, will be exposed to various types of space radiation, like charged particles produced by the Sun or energy particles trapped within Earth's atmosphere. Space radiation is known to alter molecules of DNA, which is obviously not good for human health. Upon their arrival back at Earth, data collected from the two manikins will help researchers to better understand the level of protection provided by the newly developed AstroRad vest.

Efforts to tease apart the vast swarm of proteins in venom -- a field called venomics -- have burgeoned in recent years, leading to important drug discoveries. From a report: In a small room in a building at the Arizona-Sonora Desert Museum, the invertebrate keeper, Emma Califf, lifts up a rock in a plastic box. "This is one of our desert hairies," she said, exposing a three-inch-long scorpion, its tail arced over its back. "The largest scorpion in North America." This captive hairy, along with a swarm of inch-long bark scorpions in another box, and two dozen rattlesnakes of varying species and sub- species across the hall, are kept here for the coin of the realm: their venom. Efforts to tease apart the vast swarm of proteins in venom -- a field called venomics -- have burgeoned in recent years, and the growing catalog of compounds has led to a number of drug discoveries. As the components of these natural toxins continue to be assayed by evolving technologies, the number of promising molecules is also growing.

"A century ago we thought venom had three or four components, and now we know just one type of venom can have thousands," said Leslie V. Boyer, a professor emeritus of pathology at the University of Arizona. "Things are accelerating because a small number of very good laboratories have been pumping out information that everyone else can now use to make discoveries." She added, "There's a pharmacopoeia out there waiting to be explored." It is a striking case of modern-day scientific alchemy: The most highly evolved of natural poisons on the planet are creating a number of effective medicines with the potential for many more.

One of the most promising venom-derived drugs to date comes from the deadly Fraser Island funnel web spider of Australia, which halts cell death after a heart attack. Blood flow to the heart is reduced after a heart attack, which makes the cell environment more acidic and leads to cell death. The drug, a protein called Hi1A, is scheduled for clinical trials next year. In the lab, it was tested on the cells of beating human hearts. It was found to block their ability to sense acid, "so the death message is blocked, cell death is reduced, and we see improved heart cell survival," said Nathan Palpant, a researcher at the University of Queensland in Australia who helped make the discovery.

People who have been hospitalised with Covid may be left with difficulties in thinking comparable in magnitude to ageing 20 years, research suggests. From a report: As the pandemic swept the world it became apparent that coronavirus could not only cause immediate health problems but also leave some people with often debilitating symptoms -- a condition known as long Covid. According to one UK study, about a third of patients who experienced symptoms after being hospitalised felt fully recovered a year later, with little improvement for most patients in areas including physical function and cognitive impairment. Now experts have revealed that some patients were left with, on average, a lingering cognitive decline.

David Menon, a professor at Cambridge University and senior author of the study, said the degree of impairment was linked to the severity of illness. "[Covid] does cause problems with a variety of organs in the body, including the brain and our cognitive function and our psychological health," he said. "If you can have a vaccine, and all your doses, you will have less severe illness. So all of these problems are going to be less." Writing in the eClinicalMedicine journal, Menon and colleagues report how they examined the results of cognitive tests performed by 46 patients, on average six months after they were admitted to Addenbrooke's hospital in Cambridge between March and July 2020. Of this group, 16 received mechanical ventilation.

schwit1 shares a report from Space.com: We'll have to wait at least another month to see the results of the U.S Federal Aviation Administration's (FAA) environmental review of SpaceX's Starship program. The FAA has been working for months on that review -- officially known as a programmatic environmental assessment (PEA) -- which is assessing the environmental impacts of Starbase, the South Texas site where SpaceX has been building and testing its huge Starship vehicle. The agency published a draft PEA in September and estimated that the final version would be wrapped up by the end of the year. But the FAA has repeatedly delayed the final PEA, generally by a month at a time, citing the need to analyze the public comments submitted in response to the draft report and discuss next steps with other government agencies. "The FAA plans to release the Final PEA on May 31, 2022. The FAA is finalizing the review of the Final PEA, including responding to comments and ensuring consistency with SpaceX's licensing application," FAA officials wrote in an update. "The FAA is also completing consultation and confirming mitigations for the proposed SpaceX operations. All consultations must be complete before the FAA can issue the Final PEA."

Scientists working on NASA's James Webb Telescope have reached an important milestone, completely aligning the space observatory's massive mirrors. New Atlas reports: The achievement means the team can now move ahead with configuring the onboard instruments and prepare them to begin capturing sharp and in-focus images of the cosmos. Back in January, the James Webb Space Telescope (JWST) finished deploying its set of 18 mirrors, which it will use to direct light from cosmic objects onto its instruments to capture images. But to do so, the mirrors had to be precisely aligned over a three-month period in order to focus that light correctly. In March, the mirrors were brought into alignment with the telescope's primary imaging instrument, the Near-Infrared Camera, enabling it to focus and snap a crystal-clear image of a bright star. The team then continued aligning the mirrors with the JWST's remaining instruments, the Near-Infrared Spectrograph, Mid-Infrared Instrument, and Near Infrared Imager and Slitless Spectrograph -- a task that is now complete.

The team confirmed the mirrors were aligned and directing light onto the JWST's four instruments by capturing a set of test images covering the telescope's full-field of view [...]. The scientists say the optical performance of the telescope continues to exceed even their most optimistic expectations. With the mirrors now in position (save for some slight periodic adjustments here and there), the scientists are now turning their attention to commissioning of the science instruments. The unique lenses, masks, filters and other gear that make these highly sophisticated instruments tick will need to be precisely configured over the next two months, to ready the telescope for the start of its science operations in the middle of the year.

After nearly three years of preparation, small satellite launch company Rocket Lab has successfully caught one of its rockets in mid-air today, after launching the vehicle to space from New Zealand. The Verge reports: But by catching and reusing its rockets after flight, Rocket Lab hopes to cut down on the manufacturing cost associated with building an entirely new rocket for each of its missions. The goal is similar to that of SpaceX, which has become famous for landing and reusing its rockets post-flight. Rocket Lab also claims that recovering and reusing its rockets could also help speed up its flight cadence. "By bringing one back, it just saves a tremendous amount of time where you don't have to build a whole new rocket from scratch," Peter Beck, CEO of Rocket Lab, tells The Verge. "So we'll obviously see some good cost savings, but I think the most important thing for us right now is just getting the vehicles back into the production line."

When Electron launches to space, computers on board the vehicle guide the booster back through Earth's atmosphere, maneuvering it in just the right way so that it stays intact during the fall to the ground. Once the rocket reaches an altitude of about 8.3 miles up, it deploys a drogue parachute to slow its fall, followed by a main parachute. As the rocket leisurely floats down toward the ocean, that's when the helicopter will arrive and attempt to capture the line of the parachute with a dangling hook, avoiding a splashdown in salty seawater. UPDATE 4:08PM PST: Rocket Lab confirmed the helicopter catch. The summary and headline have been updated to reflect the successful mission.

Extreme weather due to the climate crisis is expected to increasingly make some Australian homes "uninsurable," with a new report suggesting up to one in 25 households will struggle to be covered by 2030. From a report: The analysis by the Climate Council, using data from consultants Climate Valuation, mapped the 10 electorates across the country considered most at risk of becoming uninsurable due to flood, fire and other extreme weather risk. The most at-risk areas were mostly found to be in flood and cyclone-prone areas of Queensland and in parts of Victoria built over flood plains near major rivers. "Uninsurable" is defined in the report as an area where the required type of insurance product was expected to be not available, or only available at such high cost that no one could afford it.

NASA and the German Aerospace Center are permanently shutting down the Stratospheric Observatory for Infrared Astronomy (SOFIA), a telescope on an aeroplane that has been scrutinized for years for its high cost and low scientific output. From a report: Since 2014, the observatory has made hundreds of flights above the water vapour in Earth's atmosphere to get an unobscured view of celestial objects and to gather data at infrared wavelengths. SOFIA has measured magnetic fields in galaxies1, spotted water on sunlit portions of the Moon2 and detected the first type of ion that formed in the Universe, helium hydride3. But it costs NASA around $85 million a year to operate, which is nearly as much as the operational expenses for the Hubble Space Telescope. On 28 April, NASA and the German Aerospace Center, the two partners in SOFIA, announced that they will close down the observatory by 30 September.

Less than two years after Google dismissed two researchers who criticized the biases built into artificial intelligence systems, the company has fired a researcher who questioned a paper it published on the abilities of a specialized type of artificial intelligence used in making computer chips. From a report: The researcher, Satrajit Chatterjee, led a team of scientists in challenging the celebrated research paper, which appeared last year in the scientific journal Nature and said computers were able to design certain parts of a computer chip faster and better than human beings. Dr. Chatterjee, 43, was fired in March, shortly after Google told his team that it would not publish a paper that rebutted some of the claims made in Nature, said four people familiar with the situation who were not permitted to speak openly on the matter. Google confirmed in a written statement that Dr. Chatterjee had been "terminated with cause." Google declined to elaborate about Dr. Chatterjee's dismissal, but it offered a full-throated defense of the research he criticized and of its unwillingness to publish his assessment.

In 1972 — half a century ago — Charles Moss Duke walked on the moon.

Now 86 years old, he's ready for America to get back to exploring the moon, reports the Associated Press: Duke said he does not begrudge NASA for ending the Apollo program to focus on space shuttles, the international space station and other missions in more remote parts of space. But he looks forward to future missions that build off of what he and others have learned from their time on the moon, which called "a great platform for science."

Duke also noted that he's encouraged by the commercial partnerships that have developed around space exploration, like Space X and Blue Origin [and the companies he describes in their video as "the others"]. Those options, he said, "make space available for more people and more science and engineering and unmanned stuff."

"That compliment is going to be really important in the future," Duke went on.
The article notes the first of NASA's huge Space Launch System rockets is scheduled to blast off later this year, "with crewed flights planned subsequently." In the video interview, Duke adds that "With Artemis, NASA is going to be focused on deep space, to the moon and beyond, and I'm excited about that..."

"The more people we get into space, and can see the beauty of the earth — and the incredible emotion that you [feel] when you see the earth hung in the blackness of space — it's going to affect a lot of people."

Long-time Slashdot reader schwit1 shares a report from Inverse: It only took 25 years of development, 17 years of construction, eight launch delays, and five months of alignments, but finally, the James Webb Space Telescope is almost ready for prime time. New photos released by the European Space Agency — and an accompanying video from NASA — show images of stars taken by a fully aligned space telescope, instruments and all.

The image shows snapshots from each of Webb's three imaging instruments, plus its spectrograph and guidance sensor. The images show a field of stars in the Large Magellanic Cloud (LMC), a galaxy near the Milky Way about 158,000 light-years away. If it orbits our galaxy, it would be, by far, the largest satellite galaxy. But there's a chance it's just passing through or slowly merging with our galaxy.

Saudi Arabia, the world's largest oil exporter, is turning to cloud-seeding to increase rainfall. Interesting Engineering reports: The country initiated the first phase of its cloud-seeding operation in areas above the capital Riyadh, al-Qassim, and Hail on Tuesday, according to Arab News. The weather modification technique is being executed as part of an effort to increase the country's yearly rainfall, which does not exceed 100 millimeters a year, by 10 to 20 percent. Cloud-seeding is a technique that involves introducing chemicals to clouds, like small particles of silver iodide, to induce more rain from a cloud. This causes water droplets to congregate around them, and the water particles clash with one another, growing larger and increasing the likelihood of rainfall.

Ayman Ghulam, head of the National Center of Meteorology and supervisor of the cloud-seeding program, said the program's operations room opened on Monday at the center's headquarters in Riyadh, and the first flights took place in the capital's vicinity, according to Gulf News. He stated that they met their objectives in terms of the results and timeliness of the seeding operations. The center will provide quarterly updates on developments. The program will track cloud formations across the country to find the optimal locations for seeding efforts, which would use "environmentally friendly" materials to increase precipitation in targeted areas. The cloud seeding initiative, according to Gluham, is one of the "promising ways" of preserving water balance in a safe, adaptable, and cost-effective manner.

New pictures from the Ingenuity helicopter offer a fresh perspective of the wreckage left behind when the Perseverance rover landed on Mars last year, NASA said on Wednesday. The Verge reports: Launched in 2020, the Perseverance rover successfully landed on the Red Planet in 2021, with the mission of finding ancient signs of life on Mars. The rover carried the Ingenuity helicopter onboard -- an experimental project that scientists on Earth hoped would be able to see sights that the rover couldn't. Perseverance went through a grueling process known as the seven minutes of terror to descend onto the Martian surface. As it entered the atmosphere, a heat shield helped protect the rover from the blistering heat of reentry and slowed it down dramatically. After that, the massive parachute deployed out of the backshell (a cone-shaped part of the descent vehicle), slowing it down even more. At that point, the backshell and parachute separated from Perseverance and let the descent stage take over, using rocket thrusters and a "sky crane" to gently lower the rover to a smooth landing.

On April 19th, Ingenuity took photographs that captured the remains of Perseverance's parachute and the rover's protective backshell, a cone-shaped part of the descent vehicle that carried the parachute and helped protect the rover on its way to the surface. Strewn around the site were debris from where the two crashed into the surface after separating from the rover. The backshell ended up hitting the ground at about 78 miles per hour, according to NASA. From the pictures, it appears that the parachute, the lines connecting the parachute to the spacecraft, and the coating on the outside of the backshell all survived the trip to the surface, NASA says, though more analysis of the pictures will happen in the coming weeks.

From sociable labradors to aggressive pitbulls, when it comes to canine behaviour there are no end of stereotypes. But research suggests such traits may have less to do with breed than previously thought. From a report: Modern dog breeds began to emerge in the Victorian era and are often physically distinct -- for example, great danes are huge and chihuahuas tiny. But it has often been thought breed can predict behaviour, too. Now researchers say there's little sign that's the case. Dr Elinor Karlsson of the University of Massachusetts Umass Chan medical school, a co-author of the study, said research revealed a huge diversity of behaviours within each breed.

"Even if the average is different, you've still got a really good chance of getting a dog that doesn't match what people say that breed is supposed to be," she said. Writing in the journal Science, the US researchers report how they analysed survey responses relating to the physical traits and behaviour of 18,385 pet dogs, almost half of which were purebred, with genetic data analysed for 2,155 of them. Analysis of the survey results for purebred dogs suggested about 9% of behavioural variation was explained by breed.

Atmospheric analog to ocean's acoustic channel could be used to monitor eruptions and bombs. From a report: About 1 kilometer under the sea lies a sound tunnel that carries the cries of whales and the clamor of submarines across great distances. Ever since scientists discovered this Sound Fixing and Ranging (SOFAR) channel in the 1940s, they've suspected a similar conduit exists in the atmosphere. But few have bothered to look for it, aside from one top-secret Cold War operation. Now, by listening to distant rocket launches with solar-powered balloons, researchers say they have finally detected hints of an aerial sound channel, although it does not seem to function as simply or reliably as the ocean SOFAR. If confirmed, the atmospheric SOFAR may pave the way for a network of aerial receivers that could help researchers detect remote explosions from volcanoes, bombs, and other sources that emit infrasound -- acoustic waves below the frequency of human hearing. "It would help enormously to have those [detectors] up there," says William Wilcock, a marine seismologist at the University of Washington, Seattle. Although seismic sensors in the ground pick up most of the planet's biggest bangs, "some areas of the Earth are covered very well and others aren't."

In the ocean, the SOFAR channel is bounded by layers of warmer, lighter water above and cooler, denser water below. Sound waves, which travel at their slowest at this depth, get trapped inside the channel, bouncing off the surrounding layers like a bowling ball guided by bumpers. Researchers rely on the SOFAR channel to monitor earthquakes and eruptions under the sea floor -- and even to measure ocean temperatures rising from global warming. After geophysicist Maurice Ewing discovered the SOFAR channel in 1944, he set out to find an analogous layer in the sky. At an altitude of between 10 and 20 kilometers is the tropopause, the boundary between the troposphere, the lowest layer of the atmosphere (where weather occurs), and the stratosphere. Like the marine SOFAR, the tropopause represents a cold region, where sound waves should travel slower and farther. An acoustic waveguide in the atmosphere, Ewing reasoned, would allow the U.S. Air Force to listen for nuclear weapon tests detonated by the Soviet Union. He instigated a top-secret experiment, code-named Project Mogul, that sent up hot air balloons equipped with infrasound microphones.

Space rocks that fell to Earth within the last century contain the five bases that store information in DNA and RNA, scientists report April 26 in Nature Communications. Science News reports: These "nucleobases" -- adenine, guanine, cytosine, thymine and uracil -- combine with sugars and phosphates to make up the genetic code of all life on Earth. Whether these basic ingredients for life first came from space or instead formed in a warm soup of earthly chemistry is still not known. But the discovery adds to evidence that suggests life's precursors originally came from space, the researchers say. Scientists have detected bits of adenine, guanine and other organic compounds in meteorites since the 1960s. Researchers have also seen hints of uracil, but cytosine and thymine remained elusive, until now.
