SpaceX Launches 60 More Starlink Satellites and Achieves a Reusability Record For a Falcon 9 Booster (techcrunch.com) 63

SpaceX launched its second Falcon 9 rocket in the span of just four days on Wednesday at 9:25 PM EDT (6:25 PM PDT). This one was carrying 60 more satellites for its Starlink constellation, which will bring the total currently in operation on orbit to 480. From a report: The launch took off from Florida, where SpaceX's first astronaut launch took place on Saturday for the final demonstration mission of its Crew Dragon to fulfill the requirements of NASA's Commercial Crew human-rating process. Today's launch didn't include any human passengers, but it did fly that next big batch of Starlink broadband internet satellites, as mentioned. Those will join the other Starlink satellites in low Earth orbit, forming part of a network that will eventually serve to provide high-bandwidth, reliable internet connectivity, particularly in underserved areas where terrestrial networks either aren't present or don't offer high-speed connections. This launch included a test of a new system that SpaceX designed in order to hopefully improve an issue its satellites have had with nighttime visibility from Earth. The test Starlink satellite, one of the 60, has a visor system installed that it can deploy post-launch in order to block the sun from reflecting off its communication antenna surfaces. If it works as designed, it should greatly reduce sunlight reflected off the satellite back to Earth, and SpaceX will then look to make it a standard part of its Starlink satellite design going forward.

CES Will Be Held In-person in Las Vegas Next Year (theverge.com) 15

The group behind CES plans to hold the enormous tech convention in person in Las Vegas next January, despite concerns that the coronavirus pandemic may still be a threat. The Consumer Technology Association has announced that it intends to give exhibitors a way to showcase their products "both physically in Las Vegas and digitally." From a report: The stakes are high for CES. It's one of the largest conventions held each year in Las Vegas, responsible for bringing a huge number of visitors to the city, with around 175,000 attendees last year. The Las Vegas Convention Center, the primary venue where the event is held, is scheduled to complete a $980 million expansion just in time for next year's show. And while consumers may know CES as the event where new TVs, cars, and other gadgets are announced, it also remains an important venue for meetings between retailers, manufacturers, and all the companies in between.

Australian Researchers Set Record For Carbon Dioxide Capture (phys.org) 52

Researchers from Monash University and the CSIRO have set a record for carbon dioxide capture and storage (CCS) using technology that resembles a sponge filled with tiny magnets. Phys.Org reports: Using a Metal Organic Frameworks (MOFs) nanocomposite that can be regenerated with remarkable speed and low energy cost, researchers have developed sponge-like technology that can capture carbon dioxide from a number of sources, even directly from air. The magnetic sponge is used to remove carbon dioxide using the same techniques as induction cooktops using one-third of the energy than any other reported method.

In the study, published in Cell Reports Physical Science, researchers designed a unique adsorbent material called M-74 CPT@PTMSP that delivered a record low energy cost of just 1.29 MJ kg-1CO2 , 45 per cent below commercially deployed materials, and the best CCS efficiency recorded. MOFs are a class of compounds consisting of metal ions that form a crystalline material with the largest surface area of any material known. In fact, MOFs are so porous that they can fit the entire surface of a football field in a teaspoon. This technology makes it possible to store, separate, release or protect valuable commodities, enabling companies to develop high value products.

The stability of M-74 CPT@PTMSP was evaluated by estimating the amount of CO2 and H2O captured and released via the researchers' magnetic induction swing adsorption (MISA) process over 20 consecutive cycles. The regeneration energy calculated for M-74 CPT@PTMSP is the lowest reported for any solid porous adsorbent. At magnetic fields of 14 and 15 mT, the regeneration energy calculated for M-74 CPT was 1.29 and 1.44 MJ kg CO2-1.

Could Granite Solve the Hard Problem of Nuclear Waste Storage? (theguardian.com) 152

An anonymous reader quotes a report from The Guardian: A new study published in Scientific Reports reveals that crystalline rocks, such as granite, have a natural self-sealing mechanism, capable of keeping fluids locked away for millions of years. Careful analysis of the chemistry and structure of granites from Japan and the UK revealed that when fluid did enter the rock (via fractures), it travelled a few centimeters at most. The scientists believe that calcium in the rock reacted with carbonate in the fluid to create tiny crystals of calcite that plugged all the gaps and prevented further flow. "This amount of calcite would never be expected in a granite, and the distribution of it indicates it almost certainly formed from small quantities of fluid trying to move through the rock," says Roy Wogelius from the University of Manchester. Greater understanding is needed before we finalize our radioactive waste disposal strategies, but this is a promising step forward.

Governments and WHO Changed COVID-19 Policy Based On Suspect Data From Tiny US Company (theguardian.com) 140

AmiMoJo shares a report from The Guardian The World Health Organization and a number of national governments have changed their Covid-19 policies and treatments on the basis of flawed data from a little-known U.S. healthcare analytics company, also calling into question the integrity of key studies published in some of the world's most prestigious medical journals. Surgisphere, whose employees appear to include a sci-fi writer and adult content model, provided the database behind Lancet and New England Journal of Medicine hydroxychloroquine studies. Data it claims to have legitimately obtained from more than a thousand hospitals worldwide formed the basis of scientific articles that have led to changes in Covid-19 treatment policies in Latin American counties. It was also behind a decision by the WHO and research institutes around the world to halt trials of the controversial drug hydroxychloroquine. Late on Tuesday, the Lancet released an "expression of concern" about its published study. The New England Journal of Medicine has also issued a similar notice. According to an independent audit by authors not affiliated with Surgisphere, the article includes a list of "concerns that have been raised about the reliability of the database." Some of the main points include: Surgisphere's employees have little or no data or scientific background; While Surgisphere claims to run one of the largest and fastest growing hospital databases in the world, it has almost no online presence; and The firm's chief executive, Sapan Desai, has been named in three medical malpractice suits.

China Delayed Releasing Coronavirus Info, Frustrating WHO (apnews.com) 98

schwit1 shares a report: Throughout January, the World Health Organization publicly praised China for what it called a speedy response to the new coronavirus. It repeatedly thanked the Chinese government for sharing the genetic map of the virus "immediately," and said its work and commitment to transparency were "very impressive, and beyond words." But behind the scenes, it was a much different story, one of significant delays by China and considerable frustration among WHO officials over not getting the information they needed to fight the spread of the deadly virus, The Associated Press has found. Despite the plaudits, China in fact sat on releasing the genetic map, or genome, of the virus for more than a week after three different government labs had fully decoded the information. Tight controls on information and competition within the Chinese public health system were to blame, according to dozens of interviews and internal documents. Chinese government labs only released the genome after another lab published it ahead of authorities on a virologist website on Jan. 11. Even then, China stalled for at least two weeks more on providing WHO with detailed data on patients and cases, according to recordings of internal meetings held by the U.N. health agency through January -- all at a time when the outbreak arguably might have been dramatically slowed.

Coronavirus Patients Lose Senses of Taste, Smell -- and Haven't Gotten Them Back (wsj.com) 143

An anonymous reader quotes a report from The Wall Street Journal: Clinicians racing to understand the novel disease are starting to discern an unusual trend: one common symptom -- the loss of smell and taste -- can linger months after recovery. Doctors say it is possible some survivors may never taste or smell again. Out of 417 patients who suffered mild to moderate forms of Covid-19 in Europe, 88% and 86% reported taste and smell dysfunctions, respectively, according to a study published in April in the European Archives of Oto-Rhino-Laryngology. Most patients said they couldn't taste or smell even after other symptoms were gone. Preliminary data showed at least a quarter of people regained their ability to taste and smell within two weeks of other symptoms dissipating. The study said long-term data are needed to assess how long this can last in people who didn't report an improvement.

Anyone who has had the sniffles knows a stuffy nose impedes smell and taste; the novel coronavirus's ability to break down smell receptors is puzzling because it occurs without nasal congestion. One theory is that the "olfactory receptors that go to the brain -- that are essentially like a highway to the brain -- commit suicide so they can't carry the virus to the brain," said Danielle Reed, associate director of the Monell Chemical Senses Center. "It could be a healthy reaction to the virus. If that doesn't work, maybe people do get sicker," she said. "It might be a positive takeaway from what is obviously a devastating loss to people."

Class of Stellar Explosions Found To Be Galactic Producers of Lithium (phys.org) 13

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.

MIT Builds Robot Hand That Can 'See and Feel' Objects (independent.co.uk) 9

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.

New Ebola Outbreak Declared in Congo City That Last Saw the Virus in 2018 (washingtonpost.com) 56

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.

New Coronavirus 'Losing Potency', Top Italian Doctor Says (reuters.com) 224

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.

How 'Technoprogressive' Transhumanists Are Enhancing Their Bodies With Technology (cnn.com) 108

Rob Spence installed a wireless video camera in place of his right eye, reports CNN. And 29-year-old James Young's robotic arm "features a USB port, a screen displaying his Twitter feed and a retractable dock containing a remote-controlled drone..."

"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.

Watch NASA Astronauts on SpaceX Crew Dragon Docking with ISS (youtube.com) 55

"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 Opens 100 More US Stores -- With Mandatory Temperature Checks For Customers (appleinsider.com) 68

"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.

Tunguska Meteor That Blasted Millions of Trees in 1908 Might Have Returned To Space (space.com) 82

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.

Watch Live: SpaceX Launches NASA Astronauts to ISS (geekwire.com) 116

"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!"

As Coronavirus Hospitalizations Rise in the US, Many States Hide Their Data (politico.com) 167

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.

Many Scientists Warn CDC's New Death Rate Estimates Far Too Low (buzzfeednews.com) 151

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.

EU's Greenhouse Gas Emissions Continue To Fall As Coal Ditched (theguardian.com) 152

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.

Biotech Startup Aims to Make Use of Humanity's Genetic Outliers (bloomberg.com) 26

pacopico writes: A startup called Variant Bio has quietly been going around the world for the past couple of years, looking for genetic outliers. We're talking about people with super high metabolisms, amazing eyesight, the ability to hold their breaths for really long times. Variant wants to sequence their DNA and come up with a new class of drugs based off these traits found among isolated, indigenous people. The whole business is sort of the opposite of 23andMe or Ancestry where you sequence a ton of people and hope something interesting pops out. 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. Tons of ethical and moral questions but very sci-fi and at the frontier of bio-tech.
