"Thousands of disabled and elderly people in more than a dozen states have had to fight against decisions made by an algorithm to get the support services they need to remain in their homes instead of being institutionalized," reports the U.S. edition of the Guardian: The cuts have hit low-income seniors and people with disabilities in Pennsylvania, Iowa, New York, Maryland, New Jersey, Arkansas and other states, after algorithms became the arbiters of how their home health care was allocated — replacing judgments that used to be primarily made by nurses and social workers.

In Washington D.C., "on the worst end, we've had clients who actually died, because their services were cut and they were not receiving the care that they needed" Tina Smith Nelson, supervising attorney with AARP Legal Counsel for the Elderly, said about the effects of a new algorithmic system introduced in 2018. Over 300 seniors have had to file administrative appeals after their home care was cut by a new algorithmic system. "I think as a society we move into unsettling territory when we rely solely upon algorithms and data to make determinations about health care needs," Nelson said. "We reduce a person's humanity to a number...."

The situation is reflective of a reality increasingly affecting all users of American healthcare: algorithms — ranging from crude if-then charts to sophisticated artificial intelligence systems — are being deployed to make all sorts of decisions about who gets care. Government officials have touted algorithmic decision-making systems as a way to make sure that benefits are allocated even-handedly, eliminate human bias and root out fraud. But advocates say having computer programs decide how much help vulnerable people can get is often arbitrary — and in some cases downright cruel. The underlying problem, experts say, is that neither states nor the federal government provide enough funding to allow people needing health assistance to remain safely in their homes — even though these programs usually end up being much less costly than putting people in institutions. The algorithms resort to divvying up what crumbs are available...

Kevin De Liban, an attorney with Legal Aid of Arkansas, began fighting the cuts after severely disabled patients started calling "en masse" in 2016.... De Liban's legal team revealed flaws with the algorithm in court. It turned out, De Liban said, that the calculations had failed to factor in things like whether a patient had cerebral palsy or diabetes. A single point in the scoring system — for instance a point added because the patient had had a fever in the last three days or had open pressure sores — could make a huge difference in how many hours they received for the entire year... "As the algorithm worked, it was, to our eyes, pretty wildly irrational," said De Liban...

After years of court battles, Arkansas' use of the algorithmic system was finally thrown out in 2018... But across the nation, the battle continues. In Washington D.C., Pennsylvania and Iowa, legal services attorneys are plagued with calls from seniors complaining they have lost their care because of the algorithms recently adopted in those states.
The Guardian ultimately tracked down the designer of the algorithm, University of Michigan Professor Emeritus Brant Fries, who acknowledged that the system isn't even designed to calculate how many hours of care people actually need, but to try to allocate whatever scarce resources are available in the most equitable way.

"We're not saying that the size of the pie is correct... But whatever the money is there, I'm dividing it more equally!"

Pioneering pilot Wally Funk, who was denied being an astronaut because of her gender, is joining Amazon founder Jeff Bezos on an upcoming space voyage by his rocket startup, Blue Origin. Fortune reports: The nation's first female Federal Aviation Administration inspector, whose formal name is Mary Wallace Funk, will be an "honored guest" for the July 20 launch of the New Shepard rocket, Blue Origin said Thursday. At 82, Funk would be the oldest person to ever reach space, the company said, shattering the current record held by John Glenn, the astronaut-turned-senator who went into orbit at 77. Other New Shepard crew members include Bezos's brother Mark Bezos and a yet-to-be revealed auction winner who is paying $28 million to be an astronaut. Funk, an airline pilot and instructor, was a member of the "Mercury 13," a team of 13 American women who went through formal astronaut training in the early 1960s. Despite the intense preparation, the women were barred from becoming astronauts because of a then-NASA requirement to only accept military fighter pilots, a position held exclusively by men.

An anonymous reader shares a report: As early as 1958, the oil industry was hiring scientists and engineers to research the role that burning fossil fuels plays in global warming. The goal at the time was to help the major oil conglomerates understand how changes in the earth's atmosphere may affect the industry -- and their bottom line. But what top executives gained was an early preview of the climate crisis, decades before the issue reached public consciousness. What those scientists discovered -- and what the oil companies did with that information -- is at the heart of two dozen lawsuits attempting to hold the fossil fuel industry responsible for their role in climate change.

Many of those cases hinge on the industry's own internal documents that show how, 40 years ago, researchers predicted the rising global temperatures with stunning accuracy. But looking back, many of those same scientists say they were hardly whistleblowers out to take down big oil. Some researchers later testified before Congress, using their insider knowledge to highlight the ways in which the oil industry misled the public. Others say they have few qualms with how the petroleum giants handled their research. Few, however, could have predicted the imprint their work would have on history in efforts to hold the fossil fuel industry accountable for our climate emergency. The Guardian tracked down three of those scientists to see how they view their role today.

Fifty years later, physicists at MIT and elsewhere have now confirmed Hawking's area theorem for the first time, using observations of gravitational waves. Their results appear today in Physical Review Letters. MIT reports: A central law for black holes predicts that the area of their event horizons -- the boundary beyond which nothing can ever escape -- should never shrink. This law is Hawking's area theorem, named after physicist Stephen Hawking, who derived the theorem in 1971. In the study, the researchers take a closer look at GW150914, the first gravitational wave signal detected by the Laser Interferometer Gravitational-wave Observatory (LIGO), in 2015. The signal was a product of two inspiraling black holes that generated a new black hole, along with a huge amount of energy that rippled across space-time as gravitational waves. If Hawking's area theorem holds, then the horizon area of the new black hole should not be smaller than the total horizon area of its parent black holes. In the new study, the physicists reanalyzed the signal from GW150914 before and after the cosmic collision and found that indeed, the total event horizon area did not decrease after the merger -- a result that they report with 95 percent confidence. Their findings mark the first direct observational confirmation of Hawking's area theorem, which has been proven mathematically but never observed in nature until now. The team plans to test future gravitational-wave signals to see if they might further confirm Hawking's theorem or be a sign of new, law-bending physics.

An anonymous reader quotes a report from Axios: Virgin Galactic announced Thursday plans to launch its billionaire founder Richard Branson into space on July 11. The date is nine days before Jeff Bezos, founder of Virgin Galactic competitor Blue Origin, is set to take off for space. Branson will journey to space in Virgin Galactic's VSS Unity spacecraft along with two pilots and three other mission specialists as part of the company's fourth crewed mission. "After more than 16 years of research, engineering, and testing, Virgin Galactic stands at the vanguard of a new commercial space industry, which is set to open space to humankind and change the world for good," Branson said in a press release Thursday. "It's one thing to have a dream of making space more accessible to all; it's another for an incredible team to collectively turn that dream into reality," he added.

The highly contagious Delta variant is on the rise, and countries that hoped they had seen the worst of Covid-19 are being battered again. From a report: The nightmare is returning. In Indonesia, grave diggers are working into the night, as oxygen and vaccines are in short supply. In Europe, countries are slamming their doors shut once again, with quarantines and travel bans. In Bangladesh, urban garment workers fleeing an impending lockdown are almost assuredly seeding another coronavirus surge in their impoverished home villages. And in countries like South Korea and Israel that seemed to have largely vanquished the virus, new clusters of disease have proliferated. Chinese health officials announced on Monday that they would build a giant quarantine center with up to 5,000 rooms to hold international travelers. Australia has ordered millions to stay at home.

A year and a half since it began racing across the globe with exponential efficiency, the pandemic is on the rise again in vast stretches of the world, driven largely by the new variants, particularly the highly contagious Delta variant first identified in India. From Africa to Asia, countries are suffering from record Covid-19 caseloads and deaths, even as wealthier nations with high vaccination rates have let their guard down, dispensing with mask mandates and reveling in life edging back toward normalcy. Scientists believe the Delta variant may be twice as transmissible as the original coronavirus, and its potential to infect some partially vaccinated people has alarmed public health officials.

A wireless pacemaker that can dissolve in the body has been created for patients who need only temporary help to regulate their heartbeat. The Guardian reports: While pacemakers can already be used for temporary periods, experts say there are problems, including that leads placed through the skin can pose an infection risk. The external power supply and control system can become accidentally dislodged, and heart tissue can be damaged when the device is removed. Now researchers say they have developed a battery-free pacemaker that can be implanted directly on to the surface of the heart and absorbed by the body when no longer needed. The device -- which Rogers said would cost about $100 -- is free of leads and can be controlled and programmed from outside the body.

Writing in the journal Nature Biotechnology, Rogers and colleagues report how they made the device -- which is thin, flexible and weighs less than half a gram -- from materials including magnesium, tungsten, silicon and a polymer known as PLGA, all of which are compatible with the body but which undergo chemical reactions that allow them to dissolve and be absorbed over time. The device, which resembles a tiny tennis racket in shape, is powered by wireless technology in which radio frequency power from an external device is sent to a receiver within the pacemaker where it is converted into an electrical current that is used to regulate the heart. Rogers said similar technology was used in applications such as wireless charging of smartphones and electric toothbrushes.

Earlier today at around 11:45 AM EDT, Virgin Orbit successfully launched its first commercial satellites from their LauncherOne rocket, which blasted off from beneath the wing of a Boeing 747. TechCrunch reports: On board, Virgin Orbit carried seven payloads, including the first-ever defense satellite for the Netherlands, as well as cubsats developed by the U.S. Department of Defense for its Rapid Agile Launch initiative. The initiative is seeking to test the viability of flying small spacecraft to space on relatively short notice on launch platforms with increased flexibility, which Virgin Orbit's provides thanks to its ability to take off horizontally from more or less conventional runways. Virgin Orbit also carried two Earth observation satellites for Polish startup SatRevolution, and it will be delivering more in future flights to help build out that company's planned 14-spacecraft constellation.

In January, Virgin Orbit completed its final demonstration mission, reaching orbit for the first time with LauncherOne. That paved the way for this mission, and the company plans to increase the pace and frequency of its commercial missions, with at least one more planned tentatively for later this year and many more in 2022. In terms of payload capacity, Virgin Orbit's Launcher One can carry around 1,100 pounds to low Earth orbit, which compares favorably with the capacity of Rocket Lab's Electron, which can carry around 661 pounds to the same destination.

A team of researchers from Spain, France and the U.S. has found evidence of a glauconitic-like clay on Mars that suggests the planet once had habitable conditions. Phys.Org reports: In their paper published in the journal Nature Astronomy, the group describes their study of clay minerals extracted from Gale Crater by Curiosity rover back in 2016 and what they found. Back in 2016, NASA's Curiosity rover drilled into the Martian surface inside of Gale Crater. The rover then extracted samples of the clay minerals and used its instruments to analyze the material. In this new effort, the researchers have taken a close look at the results of the analysis and found that it very closely resembles glauconitic clays here on Earth.

Glauconite is an iron potassium phyllosilicate mineral. It is almost always found as ovoid shapes in sediment beds, carbonates and sandstones -- formation requires stable conditions over a long period. This is what makes the discovery of a similar clay on Mars so exciting -- it suggests that it likely formed under stable conditions for a long time, perhaps millions of years. And that suggests that for at least one part of Mars, conditions were, to some extent, suitable for life over millions of years. [...] The researchers note that their findings are not evidence of life on Mars, but suggest that there was a time during which conditions on the surface were favorable for its presence.

The amount of water in the atmosphere of Venus is so low that even the most drought-tolerant of Earth's microbes wouldn't be able to survive there, a new study has found. However, the researchers looked at data from other planets too and found that the clouds of Jupiter do provide sufficient water activity to theoretically support life. Space.com reports: The new study looked at measurements from probes that flew through the atmosphere of Venus and acquired data about temperature, humidity and pressure in the thick sulphuric acid clouds surrounding the planet. From these values, the scientists were able to calculate the so-called water activity, the water vapor pressure inside the individual molecules in the clouds, which is one of the limiting factors for the existence of life on Earth. The findings are likely a disappointment for the Venus research community, which was invigorated last September by the discovery of phosphine, a compound made of atoms of phosphorus and hydrogen that on Earth can be associated with living organisms, in Venus' atmosphere. At that time, researchers suggested the phosphines may be produced by microorganisms residing in those clouds. On Earth [...] microorganisms can survive and proliferate in droplets of water in the atmosphere when temperatures allow. However, the findings of the new study, based on data from several Venus probes, leave zero chance of anything living in the clouds of Venus [...].

However, the researchers looked at data from other planets too and found that the clouds of Jupiter do provide sufficient water activity to theoretically support life. Data collected by the Galileo probe at altitudes between 26 and 42 miles (42 and 68 kilometers) above the surface of the gas giant suggest the water activity value to sit at 0.585, just above the survivable threshold. Temperatures in this region are also just about survivable, at around minus 40 degrees F. High levels of ultraviolet radiation or lack of nutrients could, however, prevent that potential life from thriving, the researchers said, and completely new measurements would be needed to find whether it actually could be there or not.

In January last year, astronomers definitively observed, for the first time, a black hole swallowing a dead star, like a raven devouring roadkill. Then 10 days later, they saw the same act of scavenging happen again in a different, distant sector of the cosmos. From a report: Those triumphs, reported in a paper published on Tuesday in Astrophysical Journal Letters, are the latest in the still nascent field of gravitational astronomy, which is detecting the literal stretching and scrunching of space-time caused by some of the most cataclysmic events in the universe. "It's the first time that we've actually been able to detect a neutron star and a black hole colliding with each other anywhere in the universe," said Patrick Brady, a professor of physics at the University of Wisconsin-Milwaukee who serves as the spokesman for the LIGO Scientific Collaboration. Further reading: For the first time, astronomers see a black hole eating a neutron star.

An anonymous reader quotes a report from Scientific American: Behold the highest-resolution image of atoms ever seen. Cornell University researchers captured a sample from a crystal in three dimensions and magnified it 100 million times, doubling the resolution that earned the same scientists a Guinness World Record in 2018. Their work could help develop materials for designing more powerful and efficient phones, computers and other electronics, as well as longer-lasting batteries. The researchers obtained the image using a technique called electron ptychography. It involves shooting a beam of electrons, about a billion of them per second, at a target material. The beam moves infinitesimally as the electrons are fired, so they hit the sample from slightly different angles each time -- sometimes they pass through cleanly, and other times they hit atoms and bounce around inside the sample on their way out. Cornell physicist David Muller, whose team conducted the recent study, likens the technique to playing dodgeball against opponents who are standing in the dark. The dodgeballs are electrons, and the targets are individual atoms. Though Muller cannot see the targets, he can see where the "dodgeballs" end up, thanks to advanced detectors. Based on the speckle pattern generated by billions of electrons, machine-learning algorithms can calculate where the atoms were in the sample and what their shapes might be.

Previously, electron ptychography had only been used to image extremely flat samples: those merely one to a few atoms thick. The new study, published in Science, now allows it to capture multiple layers tens to hundreds of atoms thick. That makes the technique much more relevant to materials scientists, who typically study the properties of samples with a thickness of about 30 to 50 nanometers. (That range is smaller than the length your fingernails grow in a minute but many times thicker than what electron ptychography could image in the past.) "They can actually look at stacks of atoms now, so it's amazing," says Andrew Maiden, an engineer at the University of Sheffield in England, who helped develop ptychography but was not involved with the new study. "The resolution is just staggering."

New findings from a team using the international Gemini Observatory and the WIYN 3.5-meter Telescope at Kitt Peak National Observatory suggest that Earth-sized worlds could be lurking undiscovered in binary star systems, hidden in the glare of their parent stars. As roughly half of all stars are in binary systems, this means that astronomers could be missing many Earth-sized worlds. Phys.Org reports: Earth-sized planets may be much more common than previously realized. Astronomers working at NASA Ames Research Center have used the twin telescopes of the international Gemini Observatory, a Program of NSF's NOIRLab, to determine that many planet-hosting stars identified by NASA's TESS exoplanet-hunting mission are actually pairs of starsâ"known as binary starsâ"where the planets orbit one of the stars in the pair. After examining these binary stars, the team has concluded that Earth-sized planets in many two-star systems might be going unnoticed by transit searches like TESS's, which look for changes in the light from a star when a planet passes in front of it. The light from the second star makes it more difficult to detect the changes in the host star's light when the planet transits.

Using the 'Alopeke and Zorro instruments on the Gemini North and South telescopes in Chile and Hawai'i, respectively, the team observed hundreds of nearby stars that TESS had identified as potential exoplanet hosts. They discovered that 73 of these stars are really binary star systems that had appeared as single points of light until observed at higher resolution with Gemini. "With the Gemini Observatory's 8.1-meter telescopes, we obtained extremely high-resolution images of exoplanet host stars and detected stellar companions at very small separations," said Katie Lester of NASA's Ames Research Center, who led this work. Lester's team also studied an additional 18 binary stars previously found among the TESS exoplanet hosts using the NN-EXPLORE Exoplanet and Stellar Speckle Imager (NESSI) on the WIYN 3.5-meter Telescope at Kitt Peak National Observatory, also a Program of NSF's NOIRLab.

After identifying the binary stars, the team compared the sizes of the detected planets in the binary star systems to those in single-star systems. They realized that the TESS spacecraft found both large and small exoplanets orbiting single stars, but only large planets in binary systems. These results imply that a population of Earth-sized planets could be lurking in binary systems and going undetected using the transit method employed by TESS and many other planet-hunting telescopes. Some scientists had suspected that transit searches might be missing small planets in binary systems, but the new study provides observational support to back it up and shows which sizes of exoplanets are affected. The researchers report their findings in a paper via arXiv.

Alcohol is terrible for the human body, yet we've developed a strong taste for it, suggesting that it may bring other kinds of benefits. From a report: Alcoholic intoxication is an abnormal mental state characterized by reduced self-control and various degrees of euphoria or depression, brought about by the temporary impairment of a pretty big chunk of the brain. As the term suggests, it involves the ingestion of a chemical toxin, ethanol, which in small doses makes us happy, more sociable and better at thinking creatively and defusing conflicts. In progressively higher doses, it can lead to degraded motor coordination, slurred speech, violent arguments, maudlin expressions of love, inappropriate touching, injuries, blackouts, property damage and even karaoke. Why do we do it? Historically, scientists have written off our affinity for intoxication as an evolutionary mistake, a method that we've developed for tricking our biological reward system into releasing little shots of pleasure for no good reason. But this is not a satisfying explanation. It should puzzle us more than it does that humans have devoted so much ingenuity and effort to getting drunk.

[...] If alcohol were merely hijacking pleasure centers in the brain, evolution should have figured it out by now and put a firm end to this nonsense. Other vices can plausibly be seen as necessary appetites gone wrong, such as our taste for pornography or junk food. But alcohol is mind-bogglingly dangerous, both physiologically and socially. The fact that our supposedly accidental taste for it has not been eradicated by genetic or cultural evolution means that the cost of indulging in alcohol must be offset by benefits. Evidence from archaeology, history, cognitive neuroscience, psychopharmacology, social psychology, literature and genetics suggests what some of these benefits might be. For instance, the ancient and cross-cultural view of alcohol as a muse is supported by modern psychology: Our ability to think outside the box is enhanced by one or two drinks. This is why artists, poets and writers have long turned to drink. The name of the Anglo-Saxon god of artistic inspiration, Kvasir, literally means "strong ale." This is also why some modern companies that rely upon innovation, like Google, judiciously mix work with alcohol -- by, for instance, providing whiskey rooms where frustrated coders can relax and expand their minds when struggling with a challenging problem.

A mix-and-match approach to Covid vaccines -- using different brands of jab for first and second doses -- gives good protection against the pandemic virus, a UK study has found. From a report: The Com-Cov trial looked at the efficacy of either two doses of Pfizer, two of AstraZeneca, or one of them followed by the other. All combinations worked well, priming the immune system. This knowledge could offer flexibility for vaccine rollout, say experts. The trial results also hint that people who have already received two doses of AstraZeneca vaccine could have a stronger immune response if they were given a different jab as a booster if recommended in the autumn. The UK's deputy chief medical officer, Prof Jonathan Van-Tam, said there was no reason to change the current successful same dose vaccine schedules in the UK, however, given vaccines were in good supply and saving lives. But he says it might be something to look at in the future: "Mixing doses could provide us with even greater flexibility for a booster programme, while also supporting countries who have further to go with their vaccine rollouts, and who may be experiencing supply difficulties."

The most severe heat wave in the history of the Pacific Northwest is nearing its climax. The National Weather Service had predicted it would be "historic, dangerous, prolonged and unprecedented," and it is living up to its billing as it rewrites the record books. From a report: On Sunday, Portland, Ore., soared to its highest temperature in more than 80 years of record-keeping: 112 degrees. This new mark occurred just one day after hitting 108, which had broken the previous all-time record of 107. Seattle surged to 104 degrees Sunday, surpassing the old record of 103. The extraordinary heat swelled north of the international border as Canada saw its highest temperature recorded Sunday afternoon, when Lytton in British Columbia surged to 116 degrees. For perspective, that is just 1 degree from the all-time record in Las Vegas. While temperatures may have peaked Sunday afternoon in a few places, many were expected to turn even hotter on Monday or Tuesday, breaking all-time records (a number of which were initially broken Saturday and/or Sunday).

"Virgin Galactic finally has the federal government's approval to start launching customers into space from New Mexico," reports ABC News: Richard Branson's rocketship company announced the Federal Aviation Administration's updated license on Friday. It's the final hurdle in Virgin Galactic's yearslong effort to send paying passengers on short space hops. The company is working toward three more space test flights this summer and early fall, before opening the rocketship's doors to paying customers. The original plans called for company engineers to launch next to evaluate equipment, followed by a flight with Branson and then a science mission by Italian Air Force officers.

In the meantime, Blue Origin's Jeff Bezos earlier this month announced plans to ride his own rocket into space July 20 from Texas. Virgin Galactic officials acknowledged the growing chatter over whether Branson will try to beat Bezos into space. "Clearly, Sir Richard Branson's flight date has been subject to speculation for some time. At this time we do not have any further details on the upcoming flight dates," company spokeswoman Aleanna Crane wrote in an email...

More than 600 people already have reserved a ride to space. Tickets initially cost $250,000, but the price is expected to go up once Virgin Galactic starts accepting reservations again.

"China has released landing process footage from its Zhurong rover as well as video and sounds of the vehicle roving on Mars," reports Space News: Footage of the entry, descent and landing shows deployment of a supersonic disk-gap-band parachute, separation of the backshell, followed by powered descent, a hazard-avoidance hover phase, and landing... Video of the descent of the Zhurong rover from its landing platform, including sounds made by the vehicle's egress, was included in the release. The sounds were created by the metal on metal interaction of a rack and pinion system and recorded by Zhurong's climate station, which intends to capture sounds of Martian winds... The 240-kilogram Zhurong rover successfully landed in Utopia Planitia on May 14.

The deployment took place late May 21 Eastern, following a week-long series of checks and analysis of the environment. The six-wheeled, solar-powered Zhurong has since covered 236 meters on the Martian surface. An undated panorama shows Zhurong and tracks leading back to the landing platform, along with surface and horizon features...

The rover is part of the Tianwen-1 mission, China's first independent interplanetary mission. Consisting of an orbiter, a lander, and a rover, Tianwen-1 launched in July 2020. It entered Mars orbit February 10. Zhurong is equipped with six science payloads, including a laser-induced breakdown spectroscopy instrument for analysing surface elements and minerals, panoramic and multispectral imagers, a climate station, magnetometer and a ground-penetrating radar. It aims to return data on potential water-ice deposits, weather, topography and geology, complementing science carried out by missions from other space agencies.

The Tianwen-1 orbiter is currently in an 8.2-hour orbit, allowing a pass over Utopia Planitia once per sol to perform a data relay role. Zhurong has a primary mission and design lifetime of 90 sols (92 Earth days). It is currently unknown if Zhurong's mission will be extended beyond this.
Engadget argues that this footage from Mars "is as much about bragging rights as anything. Zhurong is part of China's first truly independent mission to another planet, and the country no doubt wants to highlight its accomplishments in as much detail as possible."

Long-time Slashdot reader schwit1 shares an interesting report from Science Alert: Thunderstorms that roil across the Southern Great Plains of the US are amongst the strongest of such storms on Earth... Their intensity and frequency have been increasing, yet our best climate models still struggle to predict just how and when they'll arise.

To help refine climate models for the Southern Great Plains, paleoclimatologist Christopher Maupin from Texas A&M University and colleagues used oxygen and hydrogen isotopes to track the ferocity of past storms. Water molecules based on elements wielding an additional neutron or two tend to require a little more energy to vaporize, and release more energy as they condense. This leaves a clear signature in the ratios of isotopes separated by rainfall under various conditions. By comparing the results of analyses taken today with historic ratios of hydrogen and oxygen isotopes found trapped by stalactites in Texan caves, the researchers developed an accurate picture of weather events in the past...

Using another set of isotopes, this time measuring those of uranium and thorium, the team dated the stalactites and stalagmites to around the last Ice Age, 30-50 thousand years ago. Measuring the shifts in oxygen and hydrogen isotopes down their lengths allowed the researchers to see the storms cycled from weakly to strongly organized, roughly every thousand years. The more strongly organized the complex of storms becomes, the more intense and damaging they are. They discovered these changes in thunderstorm intensities coincided with well-known, abrupt shifts in global climate, known as Dansgaard-Oeschger events.

The researchers also found these intensity increases coincide with a reduction in rain in southwestern US and greater atmospheric upwelling in the Santa Barbara Basin area. They believe the observed pattern suggests an increased frequency or intensity of the giant global atmospheric waves that drive the weather, called Rossby waves, may be providing the extra lift needed to fuel these greater storms. "Modern anthropogenic climate forcing has increasingly favored an amplification of these synoptic factors," the team wrote in their paper.

"This work will help predict trends of storms in the future," explained geoscientist Courtney Schumacher.

I sometimes talk about "the family of geeks" — how our shared experiences can bring us together.

But if that's true, there's been a death in the family.... Manatee County Administrator Scott Hopes, who is also an epidemiologist, said six unvaccinated employees, including five in the IT department, tested positive for the virus within a two-week period.

The two IT employees who died last week were identified in local media and obituaries as Mary Knight, 58, and Alphonso Cox, 53.

Hopes said that the one IT employee, 23, exposed to the virus who was vaccinated did not get infected. "This particular outbreak demonstrates the effectiveness, I believe, with the vaccine," he said to reporters Monday. "All of the cases were non-vaccinated. They were unvaccinated." He added in a news release, "Individual employees in the IT Department who were known to be fully vaccinated and who were in close proximity of those who were infected did not contract COVID-19."

But even with the outbreak, masks will remain optional for staffers returning this week, with unvaccinated workers being "encouraged but not required, to follow covid-19 prevention measures...." Manatee County, located in southwest Florida, has fully vaccinated 43 percent of its eligible population. The Manatee Board of County Commissioners repealed coronavirus safety requirements last month and strongly recommended that people visiting the County Administration Building "use their best judgment" to protect themselves from a potential spread of the virus...

When the second employee died Thursday, the decision was made to shut down the building the next day so it could be disinfected. "When you have that many cases, and you have a 40 percent fatality rate, you have to worry," Hopes said to Florida Politics. "I would prefer not to have any more employee funerals." Yet the county announced over the weekend that "face masks will be optional for the public and employees inside the facility...."

Funerals and celebration-of-life events for Knight and Cox are scheduled to take place later this week.
Thanks to Slashdot reader luis_a_espinal (a Florida-based software engineer) for sharing the story. Country administrator Hopes is concerned, reports the Sarasota Herald-Tribune, because "Of the first five cases, all were sick enough to be hospitalized or died. That's not the normal COVID variant that we saw last year." And yet... As officials work to control the outbreak, questions have been raised about how far the county can go to keep employees safe — including whether it can inquire about employees' vaccination status, since the recent victims so far have not been fully vaccinated... "We are allowed to ask," Hopes said. "But they don't have to tell us, and whatever their response is, we are not to ask any further." Manatee County School District General Counsel Mitch Teitelbaum said the school district had the same understanding of privacy laws...

[The county-owned seaport] Port Manatee had reported three new cases of COVID-19 on Monday, spurring fears that the virus was continuing to spread among the county's workforce. On Tuesday, port spokeswoman Virginia Zimmerman said the three cases had been an "aberration" and that there are not any additional cases to report. Zimmerman said the port does not inquire about employees' vaccination status, and that the port "encourages, but does not require, staff to be vaccinated."

While the county scrambles to mitigate the spread of the virus, Hopes said many county employees are grieving the loss of their coworkers.

"These weren't just colleagues," Hopes said. "These people have basically lived at work together for 20 years, and this happened quickly."
