A team of researchers, led by astrophysicist Sumner Starrfield of Arizona State University, has combined theory with both observations and laboratory studies and determined that a class of stellar explosions, called classical novae, are responsible for most of the lithium in our galaxy and solar system. The results of their study have been recently published in the Astrophysical Journal of the American Astronomical Society. Phys.Org reports: Several methods were used by the authors in this study to determine the amount of lithium produced in a nova explosion. They combined computer predictions of how lithium is created by the explosion, how the gas is ejected and what its total chemical composition should be, along with telescope observations of the ejected gas, to actually measure the composition. [Astrophysicist Sumner Starrfield of Arizona State University] used his computer codes to simulate the explosions and worked with co-author and American Astronomical Fellow Charles E. Woodward of the University of Minnesota and co-author Mark Wagner of the Large Binocular Telescope Observatory in Tucson and Ohio State to obtain data on nova explosions using ground-based telescopes, orbiting telescopes and the Boeing 747 NASA observatory called SOFIA.

Co-authors and nuclear astrophysicists Christian Iliadis of the University of North Carolina at Chapel Hill and W. Raphael Hix of the Oak Ridge National Laboratory and University of Tennessee, Knoxville provided insight into the nuclear reactions within stars that were essential to solving the differential equations needed for this study. "Our ability to model where stars get their energy depends on understanding nuclear fusion where light nuclei are fused to heavier nuclei and release energy," Starrfield said. "We needed to know under what stellar conditions we can expect the nuclei to interact and what the products of their interaction are."

Co-author and isotope cosmochemist Maitrayee Bose of ASU's School of Earth and Space Exploration analyzes meteorites and interplanetary dust particles that contain tiny rocks that formed in different kinds of stars. "Our past studies have indicated that a small fraction of stardust in meteorites formed in novae," Bose said. "So the valuable input from that work was that nova outbursts contributed to the molecular cloud that formed our solar system." Bose further states that their research is predicting very specific compositions of stardust grains that form in nova outbursts and have remained unchanged since they were formed.

Robotic hands capable of picking up objects as fragile as a crisp by "sensing" objects have been developed by researchers. The Independent reports: Two new tools built by MIT's Computer Science and Artificial Intelligence Laboratory (CSAIL) offer a breakthrough in the emerging field of soft robotics -- a new generation of robots that use squishy, flexible materials rather than traditional rigid equipment." These types of soft robots often draw inspiration from living organisms and offer numerous benefits in their versatile functionality. They are able to operate far more delicately than their rigid counterparts, but until now they have lacked the ability to perceive what items they are interacting with. To overcome this, the researchers equipped their robots with various sensors, cameras and software, allowing them to "see and classify" a range of objects.

The first robot built of research from MIT and Harvard University in 2019, where a team developed a robotic gripper in the shape of a cone. It worked by collapsing in on an object in a similar way to a Venus flytrap, allowing it to pick up a range of awkwardly shaped objects up to 100-times its weight. By adding tactile sensors, the robot was able to understand what it was picking up and adjust the amount of pressure exerted accordingly. Of the 10 objects used in the experiment, the sensors were able to identify them with an accuracy rate of more than 90 percent. The second robot made use of an innovative "GelFlex" finger, which uses a tendon-driven mechanism and an array of sensors to provide "more nuanced, human-like senses." The team now hopes to fine-tune the sensing algorithms and introduce more complex finger configurations, such as twisting.

Congo's health minister confirmed the discovery of a new Ebola case in the country's Equateur province, which last saw an outbreak of the highly deadly virus in 2018, ultimately killing 33 people there. From a report: The province's governor, Bobo Boloko Bolumbu, spoke on national radio earlier on Monday, saying there were five likely cases and that four of those infected had already died. He said the cases were found in Mbandaka, the provincial capital, which is home to more than 1 million people and is an important port city at the confluence of the Congo and Ruki rivers, which are heavily plied for trade and transport. The World Health Organization's director general, Tedros Adhanom Ghebreyesus, said later on Monday that six cases had been identified by Congo's Health Ministry. He said the WHO's response was already underway.

No cases of the novel coronavirus have been confirmed in Mbandaka, although more than 3,000 have been confirmed across Congo. The coronavirus and Ebola are unrelated. Ebola, which is endemic to Africa's tropical rainforests, is transmitted only through contact with an infected person's bodily fluids and manifests as a hemorrhagic fever accompanied in severe cases by vomiting and extensive internal bleeding. Congo has grappled for almost two years with a separate Ebola outbreak in its northeastern provinces that has killed 2,272 people so far. In April, the end of that outbreak, the country's worst, had been just days away from being declared over when new cases were found. The same region is also home to the world's largest ongoing measles outbreak. Further reading: WHO's statement. .

Reuters: The new coronavirus is losing its potency and has become much less lethal, a senior Italian doctor said on Sunday. "In reality, the virus clinically no longer exists in Italy," said Alberto Zangrillo, the head of the San Raffaele Hospital in Milan in the northern region of Lombardy, which has borne the brunt of Italy's coronavirus contagion. "The swabs that were performed over the last 10 days showed a viral load in quantitative terms that was absolutely infinitesimal compared to the ones carried out a month or two months ago," he told RAI television. Italy has the third highest death toll in the world from COVID-19, with 33,415 people dying since the outbreak came to light on Feb. 21. It has the sixth highest global tally of cases at 233,019.

However new infections and fatalities have fallen steadily in May and the country is unwinding some of the most rigid lockdown restrictions introduced anywhere on the continent. Zangrillo said some experts were too alarmist about the prospect of a second wave of infections and politicians needed to take into account the new reality. "We've got to get back to being a normal country," he said. "Someone has to take responsibility for terrorizing the country." The government urged caution, saying it was far too soon to claim victory.

"As biotechnology advances, so too may our ideas of what it means to be human." Today, we can alter our bodies in previously unimaginable ways, whether that's implanting microchips, fitting advanced prosthetic limbs or even designing entirely new senses. So-called transhumanists — people who seek to improve their biology by enhancing their bodies with technology — believe that our natural condition inhibits our experience of the world, and that we can transcend our current capabilities through science.

Ideas that are "technoprogressive" to some are controversial to others. But to photographer David Vintiner, they are something else altogether: beautiful. "Beauty is in the engineered products," said Vintiner, who has spent years photographing real-life cyborgs and body-modifiers for his upcoming book, "I Want to Believe — An Exploration of Transhumanism." Made in collaboration with art director and critic Gem Fletcher, the book features a variety of people who identify, to some degree, as "transhuman" — including a man with bionic ears that sense changes in atmospheric pressure, a woman who can "feel" earthquakes taking place around the world and technicians who have developed lab-made organs...

Though the photographer admitted that the transhumanists' claims can seem outlandish at first, he soon saw the appeal of technological self-enhancement. "If given the chance, how would you design your own body and what would you want it to say about you?" he asked.

"We're less than 10 meters away..."

"@AstroBehnken and @Astro_Doug are suited up, strapped in their seats and ready to be welcomed by the crew aboard the @Space_Station," NASA tweeted an hour ago.

They're now just 135 meters away from the space station, and you can watch the docking live on YouTube.

1,024,406 people are already watching...

"NASA astronauts Doug Hurley and Bob Behnken reported that the capsule was performing beautifully, as they closed in for the docking," reports the Associated Press. "The gleaming white capsule was easily visible from the station, its nose cone open exposing its docking hook, as the two spacecraft zoomed a few miles apart above the Atlantic, then Africa, then Asia." It's the first time a privately built and owned spacecraft is carrying crew to the orbiting lab. Hurley, the Dragon's commander, prepared to take manual control for a brief test, then shift the capsule into automatic for the linkup, 19 hours after liftoff. In case of a problem, the astronauts slipped back into their pressurized launch suits for the docking. The three space station residents trained cameras on the incoming capsule for flight controllers at SpaceX headquarters in Hawthorne, California, as well as NASA's Johnson Space Center in Houston.
UPDATE: At 7:16 PST, soft capture was successfully completed. We are now "moments away" from their boarding, with an official "welcoming ceremony" expected to happen soon.

"Apple is in the process of reopening 100 U.S. retail stores," reports Apple Insider, adding "as expected, those outlets look a lot different post-coronavirus." For example, the company is performing temperature-checks at the door and requiring facial coverings before entering the store. Apple has also indicated that it will provide facial coverings to customers if need be. As you approach the Apple Store, you should notice some changes right away. In the Lynnhaven Mall in Virginia Beach, Virginia, the Apple Store had multiple employees outside to guide customers into lines — one line for walk-ups, and another for reservations. While waiting in line, an employee asks you a series of four questions and takes your temperature:

- Do you currently have a fever?
- Do you currently have a cough?
- Are you currently experiencing any respiratory issues?
- Have you been in contact with any suspected or confirmed cases of COVID-19 in the last 14 days?

Answering "yes" to any question will prevent you from entering the store, even if wearing a mask. Answering "no" across the board will allow you to have your temperature checked. Apple assures customers that data isn't being recorded...

Apple retail is enforcing social distancing measures by mandating six feet of space between customers, reducing the number of products on display, and rearranging store features to allow for more space between them... If a device is handed from customer to employee, the employee will wipe it down on receipt, before beginning service or operation of the device. There are multiple stations with disinfecting wipes and hand sanitizer...

Customer occupancy and store hours have also been reduced, with Apple encouraging customers to purchase online or opt for curbside pickup when possible.

schwit1 quotes Space.com: A new explanation for a massive blast over a remote Siberian forest in 1908 is even stranger than the mysterious incident itself.

Known as the Tunguska event, the blast flattened more than 80 million trees in seconds, over an area spanning nearly 800 square miles (2,000 square kilometers) — but left no crater. A meteor that exploded before hitting the ground was thought by many to be the culprit. However, a comet or asteroid would likely have left behind rocky fragments after blowing up, and no "smoking gun" remnants of a cosmic visitor have ever been found.

Now, a team of researchers has proposed a solution to this long-standing puzzle: A large iron meteor hurtled toward Earth and came just close enough to generate a tremendous shock wave. But the meteor then curved away from our planet without breaking up, its mass and momentum carrying it onward in its journey through space.

"Crew Dragon's hatch is closed, securing @AstroBehnken and @Astro_Doug in the spacecraft ahead of liftoff," SpaceX tweeted an hour ago.

Livestreaming of the launch has already begun, with liftoff scheduled in about 41 minutes.

GeekWire reports: If liftoff from NASA's Kennedy Space Center in Florida occurs today at 3:22 p.m. ET (12:22 p.m. PT), it'll be a feat that America hasn't been able to perform since NASA retired its space shuttles, nearly nine years ago. "We are going to launch American astronauts on American rockets from American soil," NASA Administrator Jim Bridenstine declared during a launch-eve briefing at the space center's countdown clock.

But even Bridenstine acknowledged that's not a sure bet for today. "Weather challenges remain with a 50% chance of cancellation," he tweeted this morning. A drenching rainstorm swept over Florida's Space Coast overnight, but the skies cleared up this morning... The launch can be scrubbed at any time, all the way down to the last second, if the weather doesn't cooperate or if a technical glitch arises. If the gumdrop-shaped Crew Dragon doesn't lift off today, Sunday is an option. The chances of acceptable weather are expected to improve to 60%. The weather outlook is even better for a June 2 backup opportunity...

Hurley and Behnken, who are both experienced shuttle astronauts, are scheduled to rendezvous with the space station on Sunday and move in alongside its current occupants, NASA's Chris Cassidy and Russia's Anatoly Ivanishin. NASA hasn't yet decided how long the Dragon riders will spend in orbit. Their stay could be as short as six weeks, or as long as 16 weeks, depending on how the test mission proceeds. For the return trip, Hurley and Behnken will strap themselves back inside the Dragon and descend to an Atlantic splashdown.

This whole flight serves as an initial demonstration of the Crew Dragon's capabilities with an actual crew aboard. If the mission is successful, yet another Crew Dragon will carry four different astronauts to the space station weeks after Hurley and Behnken return.
Reuters reporter Joey Roulette also spotted NASA astronaut Garrett Reisman by the side of the road as his fellow astronauts drove by. He was holding a sign that said "Take me with you."

And GeekWire notes that NASA Administrator Jim Bridenstine sees this event as historic. "I really think, when we look into the future, we're going to see these models of doing business with public-private partnerships apply not just to low Earth orbit... but we're taking this model to the moon and even on to Mars."

UPDATE: SpaceX just tweeted that the re-usable Falcon 9 booster rocket "has landed on the Of Course I Still Love You droneship!"

In America, "Federal and state officials across the country have altered or hidden public health data crucial to tracking the coronavirus' spread, hindering the ability to detect a surge of infections as President Donald Trump pushes the nation to reopen rapidly," reports Politico: In at least a dozen states, health departments have inflated testing numbers or deflated death tallies by changing criteria for who counts as a coronavirus victim and what counts as a coronavirus test, according to reporting from POLITICO, other news outlets and the states' own admissions... About a third of the states aren't even reporting hospital admission data — a big red flag for the resurgence of the virus...

Nearly half the U.S., meanwhile, has registered rising caseloads as states press ahead with reopening the economy. While some of that reflects increased testing, an accompanying uptick in hospitalizations is worrying experts, including former FDA commissioner Scott Gottlieb... [He tweeted Sunday that "Daily covid hospitalizations showed sustained decline for two weeks but then over preceding week started to rise nationally."]

In addition to pulling back from its historic role as the central health authority during public health crises, the Centers for Disease Control and Prevention has established few firm standards for how states should monitor Covid-19 and made little overt effort to coordinate its messaging with state and local health departments. That's created a patchwork system where key health information is collected and communicated with little uniformity, and amid rising concern over whether Americans are receiving reliable reports about the pandemic fight. At least a half-dozen states have admitted to inflating their testing figures by mixing two different types of tests into its totals, a practice widely derided as scientifically unsound. In Georgia, where Gov. Brian Kemp has been among the strongest proponents of reopening, the inclusion of antibody tests inflated the state's overall testing count by nearly 78,000 — a disclosure that came a few weeks after officials posted a chart of new confirmed cases in Georgia with the dates jumbled out of order, showing a downward trajectory....

Florida has weathered a string of controversies over its evidence to support GOP Gov. Ron DeSantis' boasts that the state is faring better than most, including an attempt to block access to information on nursing home deaths and the firing of a health department official who now alleges she was pushed out for refusing to manipulate the state's data.

Slashdot reader DevNull127 quotes Buzzfeed News: Public health experts are accusing the CDC of bending under political pressure to say the coronavirus is less deadly. New CDC estimates of coronavirus death rates look suspiciously low and present almost no data to back them up, say public health experts who are concerned that the agency is buckling under political pressure to restart the economy...

While no one yet knows the coronavirus's actual death rate, the agency's range of possible rates seemed alarmingly low to many epidemiologists, compared to existing data in places both inside and outside the US. For instance, estimates of New York City's total death rate, 0.86% to 0.93%, are even higher than the CDC's worst-case scenario. Estimates from countries like Spain and Italy are also higher, ranging from 1.1% to 1.3%. Researchers also lambasted the CDC's lack of transparency about its data sources. The eight-page document disclosed almost nothing about its numbers, citing only internal data and a preprint — a study that has not been peer-reviewed — led by scientists in Iran. "This is terrible. This is way too optimistic," Andrew Noymer, an associate professor of population health at the University of California at Irvine, told BuzzFeed News, adding, "With this document, the CDC is determined to smash its credibility with the public health community of which it is supposedly a leader."

The CDC did not return multiple requests for comment...

A preliminary analysis of more than two dozen studies from Europe, China, the US, and elsewhere, conducted by Meyerowitz-Katz and colleague Lea Merone, suggests that the overall infection fatality rate is between 0.5% and 0.78%. Even the lower end of that range is higher than what the CDC says is its "best estimate" for the rate, which is about 0.26%. The CDC's proposed fatality rates "are more in line with a relatively mild seasonal flu season than with COVID-19," said Gerardo Chowell, a public health expert at Georgia State University. Those estimates are at least an order of magnitude lower than ones elsewhere in the world, he added, including South Korea, which has a case fatality rate around 0.7% and one of the highest testing rates for the coronavirus in the world....

The CDC document provided almost no sources for its projections, making it impossible for scientists to understand how it came up with them.

An anonymous reader quotes a report from The Guardian: Greenhouse gas emissions in the EU continued their fall in 2018, the latest year for which comprehensive data is available, according to a new report from Europe's environment watchdog. Emissions fell by 2.1% compared with 2017, to a level 23% lower than in 1990, the baseline for the bloc's emission cuts under the UN's climate agreements. If the UK is excluded, the decline since 1990 was smaller, standing at 20.7%.

The continuing fall, revealed in a report by the European Environment Agency, came as the result of EU-wide and country-specific policies, with energy generation showing the biggest decline in emissions as coal was phased out further and renewable power increased. Carbon dioxide emissions from transport flattened off in 2018, after rising for the previous four years, giving hope that this major source of emissions may be brought under control. However, emissions must be brought down much further and faster to satisfy the EU's obligations under the Paris agreement, campaigners said. Annual falls of about 7% are estimated to be needed to keep global heating within the Paris upper limit of 2C above pre-industrial levels.

We're talking about people with super high metabolisms, amazing eyesight, the ability to hold their breaths for really long times.

Instead, you're going to the obviously interesting spots and then trying to strike deals to get the DNA and turn the interesting genes into the basis of drugs.

SpaceX had just conducted yet another static fire test of the Raptor engine in its Starship SN4 prototype launch vehicle on Friday when the test vehicle exploded on the test stand in Boca Chica, Texas. TechCrunch reports: This was the fourth static fire test of this engine on this prototype, so it's unclear what went wrong vs. other static fire attempts. This was a test in the development of Starship, a new spacecraft that SpaceX has been developing in Boca Chica. Eventually, the company hopes to use it to replace its Falcon 9 and Falcon Heavy rocket, but Starship is still very early in its development phase, whereas those vehicles are flight-proven, multiple times over.

SpaceX had just secured FAA approval to fly its Starship prototype for short, suborbital test flights earlier this week. The goal was to fly this SN4 prototype for short distances following static fire testing, but that clearly won't be possible now, as the vehicle appears to have been completely destroyed in the explosion following Friday's test, as you can see in the stream from NASASpaceflight.com. The explosion occurred around 1:49 PM local time in Texas, roughly two minutes after it had completed its engine test fire.

A reader shares a report from Science Magazine: The end of the Devonian period, 359 million years ago, was an eventful time: Fish were inching out of the ocean, and fernlike forests were advancing on land. The world was recovering from a mass extinction 12 million years earlier, but the climate was still chaotic, swinging between hothouse conditions and freezes so deep that glaciers formed in the tropics. And then, just as the planet was warming from one of these ice ages, another extinction struck, seemingly without reason. Now, spores from fernlike plants, preserved in ancient lake sediments from eastern Greenland, suggest a culprit: The planet's protective ozone layer was suddenly stripped away, exposing surface life to a blast of mutation-causing ultraviolet (UV) radiation.

Just as the extinction set in, the spores became misshapen and dark, indicating DNA damage, John Marshall, a palynologist at the University of Southampton, and his co-authors say in a paper published in Science Advances. It's evidence, he says, that "all of the ozone protection is gone." Scientists have long believed -- at least before humanity became a force for extinction -- that there were just two ways to wipe out life on Earth: an asteroid strike or massive volcanic eruptions. But 2 years ago, researchers found evidence that in Earth's worst extinction -- the end-Permian, 252 million years ago -- volcanoes lofted Siberian salt deposits into the stratosphere, where they might have fed chemical reactions that obliterated the ozone layer and sterilized whole forests. Now, spores from the end-Devonian make a compelling case that, even without eruptions, a warming climate can deplete the ozone layer, says Lauren Sallan, a paleobiologist at the University of Pennsylvania. "Because the evidence is so strong, it will make people rethink other mass extinction events."

Chinese scientists in recent days said they had ruled out both a laboratory and an animal market in the city of Wuhan as possible origins of the coronavirus pandemic, in their most detailed pushback to date against allegations from U.S. officials and others over what might have sparked it. From a report: The director of the Wuhan Institute of Virology, at the center of allegations around a potential laboratory accident, Wang Yanyi, over the weekend told China Central Television that the coronavirus was significantly different from any live pathogen that has been studied at the institute and that there therefore was no chance it could have leaked from there. Separately, China's top epidemiologist said Tuesday that testing of samples from a Wuhan food market, initially suspected as a path for the virus's spread to humans, failed to show links between animals being sold there and the pathogen.

Gao Fu, director of the Chinese Center for Disease Control and Prevention, said in comments carried in Chinese state media, "It now turns out that the market is one of the victims." The comments, aimed at countering what Beijing perceives as efforts from top U.S. officials to focus solely on China, are unlikely to pacify critics. The Chinese officials didn't address fundamental issues, such as widespread evidence that China initially covered up the extent of the outbreak. In their calls for more global scientific collaboration to track the source of the virus, they also stopped short of endorsing widespread scientific belief that the coronavirus originated in China.

Jon Hamilton, reporting for NPR: Mounting evidence suggests the coronavirus is more common and less deadly than it first appeared. The evidence comes from tests that detect antibodies to the coronavirus in a person's blood rather than the virus itself. The tests are finding large numbers of people in the U.S. who were infected but never became seriously ill. And when these mild infections are included in coronavirus statistics, the virus appears less dangerous. "The current best estimates for the infection fatality risk are between 0.5% and 1%," says Caitlin Rivers, an epidemiologist at the Johns Hopkins Center for Health Security.

That's in contrast with death rates of 5% or more based on calculations that included only people who got sick enough to be diagnosed with tests that detect the presence of virus in a person's body. And the revised estimates support an early prediction by Dr. Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases and a leading member of the White House coronavirus task force. In an editorial published in late March in The New England Journal of Medicine, Fauci and colleagues wrote that the case fatality rate for COVID-19 "may be considerably less than 1%." But even a virus with a fatality rate less than 1% presents a formidable threat, Rivers says. "That is many times more deadly than seasonal influenza," she says. The new evidence is coming from places such as Indiana, which completed the first phase of a massive testing effort early in May.

A global natural experiment examines the time warp of life under quarantine. From a report: In April Jenny Rappaport sat down to inspect her calendar because she could not tell how many days had passed since New Jersey's stay-at-home order took effect. Before COVID-19, her life had structure and a pace, and she knew the day of the week without giving it a second thought. The pandemic has changed all of that. Several research groups have taken advantage of this unplanned natural experiment to gauge the psychological impacts of time distortions and, in turn, their effects on mental health. Psychologists know that time sense links to well-being. Its perceived slower passage can represent signs of depression or post-traumatic stress disorder (PTSD).

Rappaport's feelings jibe with the findings of preliminary studies. Overall, people seem to be experiencing time more slowly, according to data that are beginning to be compiled. In a not yet peer-reviewed preprint paper, Sylvie Droit-Volet, a time perception researcher at the University of Clermont Auvergne in France, and her colleagues show that people there report the clock moving more slowly during the lockdown. The researchers also document feelings of sadness and boredom and tie them to the overall feeling of deceleration. "Their findings directly support the emotional connection with time perception," says Philip Gable of the University of Alabama. He is also using survey data to examine how people across the U.S. experience time during the pandemic. "It's a societal event that's going to have a profound psychological influence on us," Gable says, adding that the temporal shift is an integral part of our feelings about what is happening. He plans to collect data over the next nine months, but so far has found evidence that the everyday tempo now lags. Nearly 50 percent of people experienced time dragging during March, whereas about 24 percent perceived it to be speeding up.

The hits came this week in rapid succession: A cyclone slammed into the Indian megacity of Kolkata, pounding rains breached two dams in the Midwestern United States, and on Thursday came warning that the Atlantic hurricane season could be severe. It all served as a reminder that the coronavirus pandemic, which has killed 325,000 people so far, is colliding with another global menace: a fast-heating planet that acutely threatens millions of people, especially the world's poor. From a report: Climate change makes extreme weather events more frequent and more intense. Now, because of the pandemic, they come at a time when national economies are crashing and ordinary people are stretched to their limits. Relief organizations working in eastern India and Bangladesh, for instance, say the lockdown had already forced people to rely on food aid by the time the storm, Cyclone Amphan, hit. Then, the high winds and heavy rains ruined newly sown crops that were meant to feed communities through next season. "People have nothing to fall back on," Pankaj Anand, a director at Oxfam India, said in a statement Thursday. The worst may be yet to come.

Several other climate hazards are looming, as the coronavirus unspools its long tail around the world. They include the prospect of heat waves in Europe and South Asia, wildfires from the western United States to Europe to Australia, and water scarcity in South America and Southern Africa, where a persistent drought is already deepening hunger. And then there's the locusts. Locusts. Abnormally heavy rains last year, which scientists say were made more likely by the long-term warming of the Indian Ocean, a hallmark of climate change, have exacerbated a locust infestation across eastern Africa. Higher temperatures make it more inviting for locusts to spread to places where the climate wasn't as suitable before -- and in turn, destroy vast swaths of farmland and pasture for some of the poorest people on the planet.

A third of Americans are showing signs of clinical anxiety or depression (alternative source), Census Bureau data shows, the most definitive and alarming sign yet of the psychological toll exacted by the coronavirus pandemic. The Washington Post reports: When asked questions normally used to screen patients for mental health problems, 24 percent showed clinically significant symptoms of major depressive disorder and 30 percent showed symptoms of generalized anxiety disorder. The findings suggest a huge jump from before the pandemic. For example, on one question about depressed mood, the percentage reporting such symptoms was double that found in a 2014 national survey.

How Americans responded to the question "How often have you been bothered by feeling down, depressed, or hopeless?" Someone who answered "several days" or "more than half the days" would need to show other symptoms to screen positive for clinical depression. The 2013-2014 study reflects symptoms over a two-week period, while the 2020 survey reflects symptoms over a one-week period. [...] Some groups have been hit harder than others. Rates of anxiety and depression were far higher among younger adults, women and the poor. The worse scores in young adults were especially notable, given that the virus has been more likely to kill the elderly or leave them critically ill.
