The ISS Is Getting a New Toilet This Year (space.com) 92

Later this year, the International Space Station will receive a new and improved toilet system designed to bridge the gap between current lavatorial space tech and what humans will need to make extended visits to, say, Mars, in comfort. Space.com reports: It has a fancier name, of course; officially, the commode is NASA's Universal Waste Management System (UWMS). The launch is targeted for no earlier than the fall, a NASA spokesperson confirmed to Space.com, although the agency is still determining what spacecraft will carry the new plumbing up. The toilet currently on offer on the U.S. side of the space station was designed in the 1990s and based on its shuttle counterpart, according to a detailed review of space toiletry. But the apparatus has its flaws. It can be clunky to use, particularly for women, and it is "sensitive to crew alignment on the seat," sometimes resulting in messes, according to that review.

So NASA has tried to keep the aspects that have gotten positive reviews while trimming mass and volume and making some design changes, like adjusting the shape of the seat and replacing the apparatus that compresses the waste. Another change mimics a feature of the toilet on the Russian side of the space station, where astronauts simply hook their feet into toe bars, rather than the thigh bars used on the American equivalent to anchor the astronaut in the microgravity environment. The UWMS will remain on the space station for the rest of the orbiting laboratory's lifetime, and a second toilet of the same model will fly on the Orion capsule that astronauts use to fly around the moon on the first crewed Artemis mission in NASA's ambitious lunar return plan, according to the agency.

FDA Ends Emergency Use Authorization For Hydroxychloroquine To Treat COVID-19 221

The Food and Drug Administration has ended its emergency use authorization for hydroxychloroquine and chloroquine, drugs the president touted in the fight against coronavirus. Mr. Trump took a 14-day regimen of hydroxychloroquine himself. CBS News reports: Based on the FDA's continued review of the available scientific evidence, it determined the drug is "unlikely to be effective in treating COVID-19 for the authorized uses," the FDA said. The agency added that "in light of ongoing serious cardiac adverse events and other serious side effects, the known benefits "no longer outweigh the known and potential risks."

A study published earlier this month concluded that the drug is not effective at preventing the disease. As CBS News chief medical correspondent Dr. Jon LaPook explains, controlled clinical trials are the only way to prove if a drug works better than a placebo or other treatment, or if its potential benefits outweigh the risks.

Why People Are More Honest When Writing on Their Smartphones (wsj.com) 12

The restaurant review that divulges distressing family dynamics. The Facebook post that rehashes an embarrassing encounter. The tweet that reveals a phobia few people know about. On our smartphones, we are quick to reveal private emotions and highly personal experiences to faceless strangers. From a report: Building on her earlier research that equated smartphones with adult pacifiers, Shiri Melumad, an assistant professor of marketing at the Wharton School of the University of Pennsylvania, set out to determine why we express ourselves in a more intimate, personal style on our smartphones than on our personal computers -- and how marketers can harness this behavior. In research published in March in the Journal of Marketing, Dr. Melumad conducted three field studies and two controlled experiments. One study looked at nearly 300,000 Twitter posts created in a 12-hour span. Tweets written on phones contained 47% more first-person pronouns and 52% more references to family than those written on PCs, she found.

"Consumers tend to convey feelings or thoughts that are more private or intimate on their smartphones, which is captured by the use of 'I' or 'we' and mentioning family and friends," says Dr. Melumad. A second study employed 1,380 judges as well as natural-language processing software to analyze a random sample of more than 10,000 TripAdvisor restaurant reviews. The software scan revealed that reviews written on smartphones again contained more first-person pronouns and more references to friends. And, crucially for marketers, they were judged to be more self-disclosing and, in turn, more persuasive. "Smartphone-generated content seems to be more diagnostic of how people truly feel," Dr. Melumad says. "Those reviews heightened readers' interest in visiting the restaurant." The final field study found that people were more likely to disclose personal information in response to an ad when targeted on their smartphone than on their PC.

The Pandemic Claims New Victims: Prestigious Medical Journals (nytimes.com) 76

One study promised that popular blood-pressure drugs were safe for people infected with the coronavirus. Another paper warned that anti-malaria drugs endorsed by President Trump actually were dangerous to these patients. The studies, published in the New England Journal of Medicine and The Lancet, were retracted shortly after publication, following an outcry from researchers who saw obvious flaws. From a report: The hasty retractions, on the same day this month, have alarmed scientists worldwide who fear that the rush for research on the coronavirus has overwhelmed the peer review process and opened the door to fraud, threatening the credibility of respected medical journals just when they are needed most. Peer review is supposed to safeguard the quality of scientific research. When a journal receives a manuscript, the editors ask three or more experts in the field for comments. The reviewers' written assessments may force revisions in a paper or prompt the journal to reject the work altogether. The system, widely adopted by medical journals in the middle of the 20th century, undergirds scientific discourse around the world. "The problem with trust is that it's too easy to lose and too hard to get back," said Dr. Jerome Kassirer, a former editor in chief of the New England Journal of Medicine, which published one of the retracted papers in early May. "These are big blunders." If outside scientists detected problems that weren't identified by the peer reviewers, then the journals failed, he said. Like hundreds of other researchers, Dr. Kassirer called on the editors to publish full explanations of what happened.

Two Hairstylists Who Had Coronavirus Saw 140 Clients. No New Infections Have Been Linked To the Salon, Officials Say (cnn.com) 180

No cases of coronavirus have been linked to two Missouri hairstylists who saw 140 clients last month while symptomatic, county health officials said. Both stylists worked at the same Great Clips location in Springfield. The clients and the stylists all wore face coverings, and the salon had set up other measures such as social distancing of chairs and staggered appointments, the Springfield-Greene County Health Department said last week. From a report: Of the 140 clients and seven co-workers potentially exposed, 46 took tests that came back negative. All the others were quarantined for the duration of the coronavirus incubation period. The 14-day incubation period has now passed with no coronavirus cases linked to the salon beyond the two stylists, county health officials said. During the quarantine, those who did not get tested got a call twice a day from health officials asking whether they had symptoms related to Covid-19, said Kathryn Wall, a spokeswoman for the Springfield-Green County Health Department. "This is exciting news about the value of masking to prevent Covid-19," said Clay Goddard, the county's director of health. "We are studying more closely the details of these exposures, including what types of face coverings were worn and what other precautions were taken to lead to this encouraging result."

The First Covid Vaccines May Not Prevent Covid Infection (bloomberg.com) 103

Desperation for a way to keep economies from collapsing under the weight of Covid-19 could mean settling for a vaccine that prevents people from getting really sick or dying but doesn't stop them from catching the coronavirus. From a report: Although a knock-out blow against the virus is the ultimate goal, early vaccines may come with limitations on what they can deliver, according to Robin Shattock, an Imperial College London professor leading development of an experimental shot. "Is that protection against infection?" Shattock said. "Is it protection against illness? Is it protection against severe disease? It's quite possible a vaccine that only protects against severe disease would be very useful."

As countries emerge warily from lockdowns, leaders are looking to a preventive shot as the route to return to pre-pandemic life. Fueled by billions of dollars in government investment, vaccines from little-known companies like China's CanSino Biologics and giants like Pfizer Inc. and AstraZeneca Plc are in development. At least one of the fastest-moving experimental shots has already advanced into human trials after showing an impact on severe disease -- but less so on infection -- in animals. Experts say such a product would probably be widely used if approved, even if that's as much as it contributes, until a more effective version comes to market. "Vaccines need to protect against disease, not necessarily infection," said Dennis Burton, an immunologist and vaccine researcher at Scripps Research in La Jolla, California.

'Looking at an Alien Sky': New Horizons Probe Sees Stars From a New View (space.com) 56

Long-time Slashdot reader JoeRobe writes: Space.com and other outlets are reporting on new pictures of Wolf 359 and Proxima Centauri sent back from New Horizons. The images show clear parallax between the view from Earth and from the spacecraft 6.9 billion km away. In effect, New Horizons is looking up at a visually different star field than we are... NASA has even created stereoscopic pairs to get a 3D view.
"It's fair to say that New Horizons is looking at an alien sky, unlike what we see from Earth," New Horizons principal investigator Alan Stern said in a statement, according to Space.com: New Horizons captured the imagery on April 22 and April 23, when the probe was more than 4.3 billion miles (6.9 billion kilometers) from its home planet. That's so far away that it took 6.5 hours for the data containing the photos, moving at the speed of light, to travel from New Horizons to mission scientists' inboxes... The parallax demonstration was not done for scientific purposes, Stern told Space.com (though he did note that the New Horizons imagery might find its way into textbooks that discuss the parallax effect). Rather, the main goal was public outreach and engagement, and a desire to provide us all with some cosmic poetry and perspective.

We could get more such demonstrations, and much more data, from New Horizons in the coming years. The probe remains in good health and has enough fuel to fly by yet another object in the 2020s, if a suitable target can be found and NASA approves another mission extension, Stern and other team members have said.

On Friday five New Horizons scientists answered questions on Reddit, including New Horizons contributing scientist and astrophysicist Brian May (also a guitarist for the rock group Queen).

The team pointed out they could hypothetically maintain communication with their interplanetary space probe until it's 200 times as far from the Sun as the Earth is. (It's currently just 47 times as far...) "But power will run out before we get that far...somewhere near 100 times."

A Spaceflight Engineer Recovers the Lost Software For Apollo 10's Lunar Module (youtube.com) 30

Long-time Slashdot reader destinyland writes: Vintage computing enthusiasts have recreated NASA's legendary "Apollo Guidance Computer," the 1960s-era assembly-language onboard guidance and navigation computer for the Apollo missions to the moon. Unfortunately, the software had been lost for the Apollo 10 mission (a manned "dress rehearsal" mission which flew to the moon eight weeks before Neil Armstrong's famous moonwalk mission).

But spaceflight engineer Mike Stewart found a clever way to recreate it, according to one science show on YouTube. Stewart found a print-out of an earlier version of the program, and "with the help of a small army of volunteers, Mike hand-transcribed the source listing and all of its programs..." — all 1,735 pages of it. (Though what used to take 25 minutes to compile together on a Honeywell mainframe now takes less than a second on his modern laptop.) There were also NASA memos which described the change, later versions of the program which had implemented the changes — and most importantly, a recently-discovered NASA document giving the checksum for every version of every program run on the Apollo Guidance Computer. So Stewart was able to cut-and-paste carefully-chosen code and variables from later versions of the program — based on the clues in NASA's memos — until he'd recreated a program with the exact same checksum.

There's also a separate video about the Apollo 10 code, highlighting "lighthearted comments in very serious code." (For example, to warn off people who'd change their crucial constants, they'd actually included a Latin phrase — a play on a biblical quote which translates roughly to "Don't touch these.") The ignition routine that actually lights the descent engine for the moon landing is named BURNBABY. The comment accompanying it? "OFF TO SEE THE WIZARD."

Scientists Trigger Hibernation In Mice, Could Astronauts Be Next? (upi.com) 51

"Scientists in Japan successfully triggered a hibernation-like state in mice by activating a specific group of brain cells," reports UPI, which points out that entering a hibernation-like state "could help astronauts conserve food and water, as well as avoid the ill-effects of microgravity, on long journeys through space." The research, published this week in the journal Nature, suggests even animals that don't naturally sleep through the winter are capable of hibernation...

Hibernation isn't simply prolonged sleep. When food gets scarce and winter approaches, hibernating animals begin to slow down their metabolism and drop their body temperature. During their prolonged slumber, hibernating animals quiet their brains and slow their heart rate and breathing. As a result, bears, snakes, turtles and other hibernating species are able to conserve energy. When spring arrives, the animals wake having lost a little weight, but are otherwise healthy.

Mice don't hibernate in the wild. But in the lab, researchers were able to coax mice into a hibernation-like state by activating a type of brain cell called Q neurons... During their approximately weeklong hibernation, the mice had slower heart rates, reduced oxygen consumption and slower respiration.

Study: 100% Face Mask Use Could Crush Second, Third COVID-19 Wave (sfgate.com) 340

"A new modeling study out of Cambridge and Greenwich universities suggests that face masks may be even more important than originally thought in preventing future outbreaks of the new coronavirus," reports SFGate: To ward off resurgences, the reproduction number for the virus (the average number of people who will contract it from one infected person) needs to drop below 1.0. Researchers don't believe that's achievable with lockdowns alone. However, a combination of lockdowns and widespread mask compliance might do the trick, they say. "We show that, when face masks are used by the public all the time (not just from when symptoms first appear), the effective reproduction number, Re, can be decreased below 1, leading to the mitigation of epidemic spread," the scientists wrote in the paper published Wednesday by the Proceedings of the Royal Society A.

The modeling indicated that when lockdown periods are combined with 100% face mask use, disease spread is vastly diminished, preventing resurgence for 18 months, the time frame that has frequently been cited for developing a vaccine. It also demonstrated that if people wear masks in public, it is twice as effective at reducing the R number than if face coverings are only worn after symptoms appear.

The masks don't have to be top-of-the-line surgical or respirator masks. Homemade coverings that catch only 50 percent of exhaled droplets would provide a "population-level benefit," they concluded.

Another review funded by the World Health Organization and published in the journal Lancet also concluded "that data from 172 observational studies indicate wearing face masks reduces the risk of coronavirus infection," according to the Washington Post.

A former director of America's Centers for Disease Control and Prevention said Thursday, "It's a lot less economically disruptive to wear a mask than to shut society, so I can't understand some of the resistance to mask wearing."

SpaceX vs. Space Shuttle: NASA's Falcon 9 Astronauts Compare the Differences (spaceflightnow.com) 61

NASA astronauts Doug Hurley and Bob Behnken flew to the International Space Station on SpaceX's Crew Dragon. But they're also uniquely qualified to describe what it felt like, since both had also flown twice on NASA's Space Shuttle. So how did its solid-fueled booster rockets during the first stage of lift-off compare to SpaceX's liquid-fueled booster rockets? A Slashdot reader shares their answer, in an article from Spaceflight Now: The Crew Dragon astronauts said the ride on the Falcon 9 rocket was smoother than the space shuttle for the first couple of minutes... "[O]ur expectation was, as we continued with the flight into second stage, that things would basically get a lot smoother than the space shuttle did. But Dragon was huffing and puffing all the way into orbit..." Behnken said. "A little bit less Gs, but a little bit more alive is probably the best way I would describe it." Hurley said, "it was very similar to what you saw in the Apollo 13 movie, where they staged from first to second stage... "That was the highlight of the ascent for me," Hurley said.

"So totally different than shuttle," Hurley said. "It was smooth. It got a little rougher."

The Dragon's automatic docking with the space station felt more gentle than expected, Hurley said. "The thing that really stood out to both us — and we mentioned it was soon as we docked — is we didn't feel the docking," he said. "It was just so smooth, and then we were docked. In shuttle, you felt a little bit of a jolt, nothing real heavy, but you felt it."

Hurley and Behnken also had positive reviews for their SpaceX-made pressure suits. The astronauts wore them during launch and docking, and will put them on again for their return to Earth — expected in late July or August. "They're custom designed and custom fitted, so they're very comfortable," Hurley said. The astronauts said taking off the suits and putting them on in space, without the effect of gravity, was much easier than on Earth. "We'd have to give the suits a five star rating," Behnken said....

"For us — as the test pilots, so to speak — we're there to evaluate how it does the mission, and so far it's done just absolutely spectacularly," Hurley said.

Chemical Engineers Turn Carbon Dioxide Into Useful Industrial Materials (phys.org) 52

"Chemical engineers from UNSW Sydney have developed new technology that helps convert harmful carbon dioxide emissions into chemical building blocks to make useful industrial products like fuel and plastics," reports Phys.org: The researchers, who carried out their work in the Particles and Catalysis Research Laboratory led by Scientia Professor Rose Amal, show that by making zinc oxide at very high temperatures using a technique called flame spray pyrolysis (FSP), they can create nanoparticles which act as the catalyst for turning carbon dioxide into 'syngas' — a mix of hydrogen and carbon monoxide used in the manufacture of industrial products. The researchers say this method is cheaper and more scalable to the requirements of heavy industry than what is available today...

"Syngas is often considered the chemical equivalent of Lego because the two building blocks — hydrogen and carbon monoxide — can be used in different ratios to make things like synthetic diesel, methanol, alcohol or plastics, which are very important industrial precursors," says Dr. Lovell, co-author of a paper published this week in Advanced Energy Materials. "So essentially what we're doing is converting CO2 into these precursors that can be used to make all these vital industrial chemicals..."

The researchers say in effect, they are closing the carbon loop in industrial processes that create harmful greenhouse gases... "The idea is that we can take a point source of CO2, such as a coal fired power plant, a gas power plant, or even a natural gas mine where you liberate a huge amount of pure CO2 and we can essentially retrofit this technology at the back end of these plants. Then you could capture that produced CO2 and convert it into something that is hugely valuable to industry," says Dr. Lovell.

Interview with the Science Writer Who Predicted the Pandemic 8 Years Ago (thebulletin.org) 99

In 1945, after atomic bomb detonations at Hiroshima and Nagasaki, several former Manhattan Project scientists founded the Bulletin of the Atomic Scientists. Publishing continuously since 1945, its current deputy editor, science writer DanDrollette, is also a Slashdot reader, and shared one of the nonprofit magazine's thought-provoking new interviews: In 2012, author David Quammen wrote a book, Spillover: Animal Infections and the Next Human Pandemic, that was the result of five years of research on scientists who were looking into the possibility of another Ebola-type disease emerging. The consensus: There would indeed be a new disease, likely from the coronavirus family, coming out of a bat, and it would likely emerge in or around a wet market in China.

But what was not predictable was how unprepared we would be.

Quammen: For 15 years, scientists have said: "Watch out for coronaviruses; they could be very dangerous." And for five years, Chinese scientist Zhengli Shi at Wuhan Institute of Virology has been warning us to watch out for the coronaviruses found in Chinese bats; SARS is a coronavirus, and it came out of Chinese bats in 2003. That was very dangerous to humans, but it didn't transmit as readily as this one does. But Shi and her group saw a virus very similar to it in bats in a cave in Yunnan Province and published a paper in 2017 saying, "Watch out for these particular coronaviruses in these horseshoe bats. They necessitate the highest preparedness." That was three years ago...

Everything about this outbreak was predictable, to me and to the scientists I was listening to, 10 years ago.

In America, Only Three States Use Google-Apple Contact Tracing App (nbcnews.com) 42

NBC News reports that in various parts of America, "States that had committed to using contact tracing apps or expressed interest are now backing away from those claims." The few states that have rolled them out have seen only tepid responses. And there are no indications of any momentum for the apps at a national level... A survey of state health officials from Business Insider this week showed that only three states — Alabama, North Dakota and South Carolina — said they were going to use the software provided by Apple and Google. The number hasn't grown since the same three states reported interest last month, and none has launched an app with the Google-Apple software...

Even the World Health Organization has piled on. "Digital tools do not replace the human capacity needed to do contact tracing," WHO Director-General Tedros Adhanom Ghebreyesus said at a briefing this week, adding that more evidence was needed and that the WHO would convene experts to share information...

A handful of states — North Dakota, South Dakota and Utah — launched apps without the support of Apple and Google, but none saw widespread adoption. More states, including Washington, have considered doing so or have launched test versions, and it's possible that apps will gain momentum closer to the fall, when they might be taken up by more employers, schools and universities and at related football games.

Two months ago Google and Apple announced a joint project to build a contact-tracing app -- which was supported by the governor of America's most populous state, California. But now a spokesperson for California's public health department tells NBC News that the state isn't currently using any apps or cellphone tracking technology.

"Most of the contact tracing work (notifying people who have been in close contact with an infected person to prevent the disease from spreading to others) can be done by phone, text, email and chat."

Trump Hasn't Followed Through On Plan To Withdraw US From WHO (arstechnica.com) 197

An anonymous reader quotes a report from Ars Technica: On May 29, President Trump said his administration would take immediate action to withdraw the U.S. from the World Health Organization. "Because they have failed to make the requested and greatly needed reforms, we will be today terminating our relationship with the World Health Organization, and redirecting those funds to other worldwide and deserving, urgent global public health needs," Trump said at the time, while criticizing the WHO's response to the coronavirus pandemic and claiming that "China has total control" over the United Nations agency.

But now, two weeks later, there's nothing to indicate that Trump has followed through on his plan. In an article yesterday titled "U.S. hasn't taken action to withdraw from WHO despite Trump pledge," The Hill wrote that "no steps toward a formal withdrawal have been taken," and that "a WHO spokesman told The Hill that the agency had received no formal notification that the United States would withdraw." Another article yesterday in Stat, a health news website, said that "none of the levers that would need to be pulled to follow through on [Trump's WHO] decision has been pulled." For example, the Trump administration has "not paid outstanding financial obligations to the WHO, a step that would be required before the United States could pull out under a joint resolution signed by Congress," the article said.
These reports follow a Vanity Fair article published Monday that describes "the secret plan to unwithdraw from the WHO after Trump's 'bizarre,' 'ruinous' exit." The article continued:

"Now, Vanity Fair has learned, secret negotiations aimed at reversing Trump's decision have begun between [U.S.] Ambassador [Andrew] Bremberg and the WHO's director general, Dr. Tedros Adhanom Ghebreyesus. A phone call Saturday between the two men resulted in a possible framework agreement to restore the relationship, which the U.S. diplomatic corps views as essential to the global fight against coronavirus and myriad other public health issues.

"The framework would allow for both increased scrutiny of China's conduct and an independent review of the WHO's performance in the first six months of the outbreak. And discussions continue over whether the WHO would exert pressure on China to turn over original samples of the live virus and allow its scientists to be interviewed regarding the virus's origins. 'It's fair to say the US is not out of WHO, and negotiations are ongoing to address concerns and hopefully walk back from this decision,' said an official who participated in a call with G7 partners, an alliance of countries with advanced economies, where this information was shared."

Young US Men Having a Lot Less Sex In the 21st Century, Study Shows (reuters.com) 307

Sexual activity among young American men has declined sharply since 2000, with nearly a third reporting no sex with a partner in the prior year, according to a survey study published on Friday that suggests social media and electronic gaming might be filling the void. Reuters reports: The survey found that from 2000 to 2018, nearly one in three U.S. men aged 18 to 24 reported no sexual activity in the past year. Lack of sexual activity, or sexual inactivity, was also on the rise among men and women aged 25 to 34 years during the survey period, the report in the journal JAMA Network Open found. Possible reasons for the decline in sexual frequency may also include stress of juggling work and intimate relationships, as well as the prevalence of other forms of solo entertainment.

"There are now many more choices of things to do in the late evening than there once were and fewer opportunities to initiate sexual activity if both partners are engrossed in social media, electronic gaming, or binge watching," Jean Twenge, from the department of psychology in San Diego State University said in an editorial accompanying the report.

Scientists Have Discovered Vast Unidentified Structures Deep Inside the Earth (vice.com) 84

Scientists combed through nearly 30 years of earthquake data to probe huge and mysterious objects near the Earth's core. From a report: Scientists have discovered a vast structure made of dense material occupying the boundary between Earth's liquid outer core and the lower mantle, a zone some 3,000 kilometers (1,864 miles) beneath our feet. The researchers used a machine learning algorithm that was originally developed to analyze distant galaxies to probe the mysterious phenomenon occurring deep within our own planet, according to a paper published on Thursday in Science. One of these enormous anomalies, located deep under the Marquesas Islands, had never been detected before, while another structure beneath Hawaii was found to be much larger than previously estimated.

Scientists led by Doyeon Kim, a seismologist and postdoctoral fellow at the University of Maryland, fed seismograms captured from hundreds of earthquakes that occurred between 1990 to 2018 into an algorithm called Sequencer. While seismological studies tend to focus on relatively small datasets of regional earthquake activity, Sequencer allowed Kim and his colleagues to analyze 7,000 measurements of earthquakes -- each with a magnitude of at least 6.5 -- that shook the subterranean world under the Pacific Ocean within the past three decades. "This study is very special because, for the first time, we get to systematically look at such a large dataset that actually covers more or less the entire Pacific basin," Kim said in a call. Though scientists have previously mapped out structures deep inside Earth, this study presents a rare opportunity to "bring everything in together and try to explain it in a global context," he noted.

NASA Selects Astrobotic To Fly Water-Hunting Rover to the Moon (nasa.gov) 16

NASA has awarded Astrobotic of Pittsburgh $199.5 million to deliver NASA's Volatiles Investigating Polar Exploration Rover (VIPER) to the Moon's South Pole in late 2023. From a report: The water-seeking mobile VIPER robot will help pave the way for astronaut missions to the lunar surface beginning in 2024 and will bring NASA a step closer to developing a sustainable, long-term presence on the Moon as part of the agency's Artemis program. "The VIPER rover and the commercial partnership that will deliver it to the Moon are a prime example of how the scientific community and U.S. industry are making NASA's lunar exploration vision a reality," said NASA Administrator Jim Bridenstine. "Commercial partners are changing the landscape of space exploration, and VIPER is going to be a big boost to our efforts to send the first woman and next man to the lunar surface in 2024 through the Artemis program."

VIPER's flight to the Moon is part of NASA's Commercial Lunar Payload Services (CLPS) initiative, which leverages the capabilities of industry partners to quickly deliver scientific instruments and technology demonstrations to the Moon. As part of its award, Astrobotic is responsible for end-to-end services for delivery of VIPER, including integration with its Griffin lander, launch from Earth, and landing on the Moon.

Plastic Rain In Protected Areas of the United States (wired.com) 81

Writing today in the journal Science, researchers report a startling discovery: After collecting rainwater and air samples for 14 months, they calculated that over 1,000 metric tons of microplastic particles fall into 11 protected areas in the western U.S. each year. That's the equivalent of over 120 million plastic water bottles. Wired: To quantify just how bad the problem has become across the American West, the researchers used collectors in 11 national parks and protected areas, sampling both rain and air. Each had a "wet" bucket to collect rainwater, and a "dry" bucket to collect air. A sensor would detect rainfall and open up the "wet" bucket while closing the dry one. And vice versa when it's sunny out, so the dry bucket would collect microplastic particles carried on the wind while the wet bucket stayed shut. The researchers also modeled where each particular storm they collected rain from had originated, looking at the size of the cities it traveled through before dumping water, and microplastics, into the wet bucket.

Overall, they found that a stunning 98 percent of samples collected over a year contained microplastic particles. On average, 4 percent of captured atmospheric particulates were actually synthetic polymers. The particles that fell in rain were larger than those deposited by wind -- lighter particles are more easily caught up in air currents. Microfibers, from sources like polyester clothing, made up 66 percent of the synthetic material in wet samples and 70 percent in dry samples. Plus, the team wasn't able to count clear or white particles and fibers with their equipment, so their tally is likely conservative.

MIT Ends Elsevier Negotiations (mit.edu) 40

New submitter gam shares an announcement from MIT: Standing by its commitment to provide equitable and open access to scholarship, MIT has ended negotiations with Elsevier for a new journals contract. Elsevier was not able to present a proposal that aligned with the principles of the MIT Framework for Publisher Contracts.

Developed by the MIT Libraries in collaboration with the Ad Hoc Task Force on Open Access to MIT's Research and the Committee on the Library System in October 2019, the MIT Framework is grounded in the conviction that openly sharing research and educational materials is key to the Institute's mission of advancing knowledge and bringing that knowledge to bear on the world's greatest challenges. It affirms the overarching principle that control of scholarship and its dissemination should reside with scholars and their institutions, and aims to ensure that scholarly research outputs are openly and equitably available to the broadest possible audience, while also providing valued services to the MIT community. More than 100 institutions, ranging from multi-institution consortia to large research universities to liberal arts colleges, decided to endorse the MIT Framework in recognition of its potential to advance open scholarship and the public good.
"We hope to be able to resume productive negotiations if and when Elsevier is able to provide a contract that reflects our community's needs and values and advances MIT's mission," said Chris Bourg, director of the MIT Libraries. "In the meantime, we will continue to use the framework to pursue new paths to achieving open access to knowledge..."
