An anonymous reader shares an excerpt from a report via ProPublica: Private equity-backed medical staffing companies that have cut doctors' pay are continuing to spend millions on political ads, according to Federal Communications Commission disclosures. The ads amount to $2.2 million since Health and Human Services Secretary Alex Azar declared a public health emergency on Jan. 31. About $1.2 million has been spent since President Donald Trump's national emergency declaration on March 13, the disclosures show.

The companies behind the ads, TeamHealth and Envision Healthcare, are among the staffing firms that have cut pay and benefits for emergency room doctors and other medical workers. The companies say the cuts are needed to cope with falling income because non-coronavirus patients are avoiding hospitals. Executives at TeamHealth and Envision also took pay cuts. But Envision and TeamHealth have continued to pour money into a joint political ad campaign. Their TV and radio spots are aimed at pressuring lawmakers working to address "surprise billing," where patients get stuck with huge medical costs from out-of-network providers they had no say in choosing. The ads oppose capping out-of-network costs based on median prices in the area. The spending totals don't include digital ads, which aren't reported to the FCC.

An anonymous reader quotes a report from the BBC: The first human trial in Europe of a coronavirus vaccine has begun in Oxford. Two volunteers were injected, the first of more than 800 people recruited for the study. Half will receive the Covid-19 vaccine, and half a control vaccine which protects against meningitis but not coronavirus. The design of the trial means volunteers will not know which vaccine they are getting, though doctors will. The vaccine was developed in under three months by a team at Oxford University. Sarah Gilbert, professor of vaccinology at the Jenner Institute, led the pre-clinical research.

The vaccine is made from a weakened version of a common cold virus (known as an adenovirus) from chimpanzees that has been modified so it cannot grow in humans. The Oxford team has already developed a vaccine against Mers, another type of coronavirus, using the same approach -- and that had promising results in clinical trials. The only way the team will know if the Covid-19 vaccine works is by comparing the number of people who get infected with coronavirus in the months ahead from the two arms of the trial. That could be a problem if cases fall rapidly in the UK, because there may not be enough data. Researchers say they hope to have one million doses ready by September, and to dramatically scale up manufacturing after that, should the vaccine prove effective.

"A larger trial, of about 5,000 volunteers, will start in the coming months and will have no age limit," the report adds. There's also another team at Imperial College London that hopes to begin human trials of its coronavirus vaccine in June.

An anonymous reader quotes a report from IEEE Spectrum: Underwater quantum links are possible across 30 meters (100 feet) of turbulent water, scientists have shown. Such findings could help to one day secure quantum communications for submarines. [...] In the new study, researchers experimented with quantum communications in a "flume tank," a water tank in which scientists can generate waves to mimic the ocean. They also tried two different strategies for quantum communications -- one involving just the polarization of the light, and the other incorporating the polarization and the orbital angular momentum of the signals -- to analyze how quantum communication protocols might differ in maximum distances and data transfer rates.

The researchers achieved quantum communication at up to 72 kilobits per second across up to 30 meters of turbulent water, the longest distance yet reported for such links. Although turbulence did result in significant wandering and distortion of light signals, those error rates didn't prevent quantum links from successfully being established with either communication protocol. Unexpectedly, the researchers found they could keep quantum communication going even while the transmitter moved down the flume tank. "We had expected that this would not be possible without beam-tracking technology," says Felix Hufnagel, a lead author and quantum physicist at the University of Ottawa in Canada. After the scientists analyzed their data, they suggested the maximum distance for secure quantum communications might actually be 80 meters in turbulent water, although this would depend on factors such as the efficiency of the detectors used. Improving such factors might significantly boost the maximum communications distance, they say. The findings have been detailed in a preprint article on April 9.

A Spot robot carrying an iPad allows doctors to interview possibly infected patients at a safe distance. [Spot is also carrying a pouch near the robot's "tail," which allows it to deliver small items such as bottled water to infected patients, without the need to send in a nurse. The report adds that an upgraded model will add cameras that can measure a patient's respiration rate and body temperature, with no need to make physical contact.] An anonymous Slashdot reader also shares news that Boston Dynamics today open-sourced its health care robotics toolkit on GitHub. "The company hopes that existing Boston Dynamics customers and other mobile robot providers can use the toolkit, which includes documentation and CAD files of enclosures and mounts, to help health care workers and essential personnel and ultimately save lives," reports VentureBeat. "The mobile robot provider outlined four use cases for its toolkit: telemedicine (which it has already deployed), remote vitals inspection, disinfection, and delivery."

One of every five New York City residents tested positive for antibodies to the coronavirus, according to preliminary test results described by Gov. Andrew M. Cuomo on Thursday, suggesting the virus had spread far more widely than known. The New York Times reports: The results also provided the tantalizing prospect that many New Yorkers who never knew they had been infected -- possibly as many as 2.7 million, the governor said -- had already encountered the virus, and survived. Mr. Cuomo also suggested the death rate was far lower than believed. The reliability of some early antibody tests to hit the market has been widely questioned, with some -- made in China without Food and Drug Administration approval -- found by health officials to be deeply flawed. Researchers across New York have worked in recent weeks to develop and validate their own, with federal approval.

In New York City, about 21 percent, or one of every five residents, tested positive for coronavirus antibodies during the state survey. The rate was 16.7 percent in Long Island, 11.7 percent in Westchester and Rockland Counties, and 3.6 percent in the rest of the state. Almost 14 percent of those tested in New York were positive, according to preliminary results from the state survey, which sampled approximately 3,000 people over two days at grocery and big-box stores. The governor suggested on Thursday that, based on the survey, the death rate in New York from Covid-19 would likely be far lower than previously believed, possibly 0.5 percent of those infected. On Thursday, Mr. Cuomo did not talk about any potential for immunity among those previously infected.

The biggest assessment of global insect abundances to date shows a worrying drop of almost 25% in the last 30 years, with accelerating declines in Europe that shocked scientists. From a news report: The analysis combined 166 long-term surveys from almost 1,700 sites and found that some species were bucking the overall downward trend. In particular, freshwater insects have been increasing by 11% each decade following action to clean up polluted rivers and lakes. However, this group represent only about 10% of insect species and do not pollinate crops. Researchers said insects remained critically understudied in many regions, with little or no data from South America, south Asia and Africa. Rapid destruction of wild habitats in these places for farming and urbanization is likely to be significantly reducing insect populations, they said. Insects are by far the most varied and abundant animals, outweighing humanity by 17 times, and are essential to the ecosystems humanity depends upon. They pollinate plants, are food for other creatures and recycle nature's waste.

Daniel Oberhaus writes via Wired: Later this summer, physicists at the Argonne and Fermi national laboratories will exchange quantum information across 30 miles of optical fiber running beneath the suburbs of Chicago. One lab will generate a pair of entangled photons -- particles that have identical states and are linked in such a way that what happens to one happens to the other -- and send them to their colleagues at the other lab, who will extract the quantum information carried by these particles of light. By establishing this two-way link, the labs will become the first nodes in what the researchers hope will one day be a quantum internet linking quantum computers around the nation. [...] The problem is that quantum information hates long-distance travel. Send entangled photons out into the real world through optical fiber and, in less than 50 miles, environmental interference will destroy their quantum state. But if the photons were relayed through a satellite instead, they could be sent to destinations hundreds -- and potentially thousands -- of miles away. So in 2018, NASA partnered with MIT's Lincoln Laboratory to develop the technologies needed to make it happen.

The goal of the National Space Quantum Laboratory program, sometimes referred to as Quantum Technology in Space, is to use a laser system on the International Space Station to exchange quantum information between two devices on Earth without a physical link. The refrigerator-sized module would be attached to the outside of the space station and would generate the entangled photons that carry the quantum information to Earth. The demonstration would pave the way for a satellite that could take entangled particles generated in local quantum networks and send them to far-flung locations.

The first pets in the United States, two cats from New York State, have tested positive for the virus that is causing the worldwide pandemic, the Agriculture Department and the Centers for Disease Control announced Wednesday. The New York Times reports: The cats, from different parts of the state, are showing only mild symptoms and are expected to be fine. Testing positive does not mean the cats have the same illness that people have. Nor does it mean that the cats can pass on the illness to people. And tests for pets are not the same as those for people, so no humans missed out on testing because the cats were tested.

Veterinarians took samples from both cats that were tested at a private lab. The test results were then confirmed at a national veterinary lab. The owners brought both cats to veterinarians because they showed symptoms of a respiratory infection. One owner had tested positive for the virus. No human in the other cat's household tested positive. The Agriculture Department and the C.D.C. emphasized that "there is no evidence that pets play a role in spreading the virus in the United States." Other experts agree that people should not start looking at their cats with suspicion. If anything, it's the other way around. The CDC recommends keeping cats indoors. And for people who become sick with COVID-19, they recommend isolating from pets as much as possible, treating them as you would a human being.

"Dogs are less susceptible to infection with the virus," the report notes. "Although there is some evidence that they may have low-level infections, they haven't shown any symptoms. Nonetheless, the C.D.C. recommends that you put dogs on a six-foot leash when walking them, keep them away from other animals and avoid contact as much as possible with any pets if you are sick."

An anonymous reader quotes a report from CNN: Lockdowns restricting travel and industry imposed to halt the spread of coronavirus have resulted in unprecedented reductions in deadly air pollution around the world, new analysis shows. Major cities that suffer from the world's worst air pollution have seen reductions of deadly particulate matter by up to 60% from the previous year, during a three-week lockdowns period. Researchers from IQAir -- a global air quality information and tech company -- studied 10 major cities around the world which have relatively high numbers of coronavirus cases and Covid-19 lockdown measures.

The study compared levels of harmful microscopic particulate matter known as PM 2.5. The pollutant, which is smaller than 2.5 micrometers in diameter, is considered particularly dangerous as it can lodge deep into the lungs and pass into other organs and the bloodstream, causing serious health risks. Seven out of the 10 cities studied, including New Delhi, Seoul, Wuhan and Mumbai, saw significant improvements in air quality. Those with historically higher levels of PM2.5 pollution witnessed the most substantial drops in pollution. The report was released to coincide with the 50th anniversary of Earth Day, which this year is focused on climate action. The report's authors say that while they do expect air pollution to rise again when economies restart after coronavirus, "out of these extraordinary circumstances, we can see how changes in our society's activities can have a momentous impact on our environment and the air we breathe," said IQAir's marketing specialist Kelsey Duska.

Rei writes: A paper recently published by The American Society of Tropical Medicine and Hygiene adds further support to recent CDC guidelines for minimizing the use of invasive ventilators. As physicians had been voicing concern that doctors were being too eager to put patients on invasive ventilation and may be doing more harm than good, the investigators looked into outcomes of intubated patients vs. non-intubated patients experiencing hypoxia. Unlike with other forms of pneumonia, they found that COVID-19 patients were unusually damaged by invasive ventilation but also able to tolerate higher levels of anoxia -- to the point that one doctor recalls having to tell patients to get off their cellphones so that they could be intubated. The recommendation is that guidelines be adjusted to discourage invasive ventilation unless a patient is physically struggling to breathe, rather than relying strictly on oxygen levels; otherwise, the use of non-invasive ventilation, such as CPAP and BiPAP, should be encouraged. When invasive ventilation is used, oxygen levels should be minimized in order to reduce the risk of damaging healthy tissue.

The first American to die of COVID-19 took place in early and mid-February, according autopsies at the Santa Clara Medical Examiner-Coroner. "Until the new revelations, the first COVID-19 death had been identified as a man in his 50s in Washington state who died Feb. 29," reports The Hill. From the report: The two people died at home on Feb. 6 and Feb. 17, making them the earliest-known victims of the coronavirus in the United States, the Santa Clara County public health department confirmed in a statement on Tuesday. The county health department said both individuals "died at home during a time when very limited testing was available only through the CDC." "Testing criteria set by the CDC at the time restricted testing to only individuals with a known travel history and who sought medical care for specific symptoms," it added. "As the Medical Examiner-Coroner continues to carefully investigate deaths throughout the county, we anticipate additional deaths from COVID-19 will be identified."

Santa Clara County officials did not identify either of the two individuals who died, whether they had traveled to Wuhan or elsewhere, or whether they had contact with the few people who had been diagnosed with the disease before they died. But reclassifying their deaths as related to the coronavirus suggests the virus had been spreading through the United States for much longer than was initially thought -- potentially for weeks or even months longer.

SpaceX has launched another big batch of Starlink satellites, the low Earth orbit spacecraft that will provide connectivity for its globe-spanning high-bandwidth broadband internet network. This brings the total number of Starlink satellites on orbit to 422, though the company plans to de-orbit two of those (the first two prototypes launched) shortly. From a report: Already, SpaceX is the largest private satellite operator in existence -- by a wide and growing margin. It's also managed to keep up the frequent pace of its Starlink launches despite the global COVID-19 crisis, with its last launch taking place March 18. In total, it has flown four such missions since the start of the year, just four months into 2020. The company has good reason to want to keep up that aggressive pace: Each launch brings it closer to the eventual launch of the Starlink broadband service that the satellites will provide the network backbone for. SpaceX wants that network to be live with coverage available in Canada and the Northern U.S. by sometime later this year, and because of the way its approach works, with small satellites orbiting much closer to Earth than traditional geostationary internet satellites and handing off the connection to one another as they pass the coverage area, they need a whole lot of them to provide stable, reliable, low-latency connections for consumers and businesses.

To commemorate Earth Day, Intel -- in partnership with Accenture and Sulubaai Environmental Foundation, a Philippine-based nonprofit dedicated to protecting Palawan's natural resources -- detailed Project Corail, an AI-powered platform that monitors and analyzes the resiliency of coral reefs. From a report: Since its launch in May 2019, it's collected 40,000 images of the reef surrounding Pangatalan Island, which researchers have leveraged to gauge reef health in real time. If the pilot program in Palawan is successful, Project Corail could be used to monitor more of the world's at-risk reef population. (Stresses such as pollution, overfishing, and global climate change will kill an estimated 90% of reefs in the next century.) It's a worthwhile mission considering that reefs not only protect coastlines from tropical storms, but that they provide food and income for 1 billion people, generating $9.6 billion from tourism and recreation alone each year. Project Corail consists of a buoy equipped with marine-grade solar panels, batteries, and a transmitting device (either Wi-Fi or 4G), as well as a camera attached to the mooring line. An Intel Neural Compute Stick 2 plugged into a Raspberry Pi handles on-buoy computing, while an onshore PC processes images with an Intel Arria 10 FPGA.

Health officials have prioritised two clinical trials that will be supplied with blood from recovered Covid-19 patients in the hope that transfusions can help save the lives of people hospitalised with the infection. From a report: NHS Blood and Transplant (NHSBT) has started to collect blood from recovered patients with a view to using the antibody-rich serum to boost the immune systems of patients struggling to overcome the virus. The limited supply of convalescent plasma will be given to patients enrolled on sub-studies in the Recovery trial led by Peter Horby at the University of Oxford, and the Remap-Cap trial led by the Intensive Care National Audit and Research Centre (ICNARC) in London. The Recovery trial will assess whether the plasma helps patients to recover before they are admitted to intensive care, while the Remap-Cap trial will investigate whether similar transfusions help to save patients who are already in high-dependency or intensive care units. At least one trial that was designed to assess whether the plasma could protect healthy people who are in close contact with Covid-19 patients, such as NHS staff and family members, was rejected by NHSBT amid a shortage of the donated serum.

An anonymous reader quotes a report from MIT Technology Review: Facebook has released a map showing the proportion of people who say they have experienced coronavirus symptoms in each state in the US. The data was gathered from more than one million Facebook users who filled in a survey created by Carnegie Mellon University about whether they were experiencing symptoms like a cough or a fever. The map, which goes down to county level, will be updated every day. Facebook says it will create similar maps for other countries in the coming days and weeks, also based on survey responses.

Knowing who is experiencing symptoms and where could help health officials and governments to prepare for surges of hospital cases and decide where to allocate resources like ventilators, face masks, and personal protective equipment. Given the shortage of tests, and long delays for results, this map could be useful in helping to predict where COVID-19 hot spots are forming across the U.S. Obviously, the map is only as good as the data that's used to create it, and as you can see for yourself, vast swaths of the map don't have enough participants to yield reliable data. The map is part of Facebook's work with CMU and the CDC to predict the coronavirus's spread.

The sandbox video game Minecraft has teamed with the United Nations for a PSA campaign that aims to spread helpful information and health tips amid the coronavirus pandemic. From the Hollywood Reporter: In an official blog post on Tuesday, a spokesperson from the game's Swedish developer wrote, "At Mojang, we find that distributing factual information is incredibly important, as that information will help people make informed decisions, which in turn may save lives. One thing we're doing to help is teaming up with the United Nations Development Programme (UNDP) and their partner, Heart17. Together, we'll spread the word under the banner of #TomorrowTogether."

The blog post noted that over the next week or so, Minecraft's social media channels will be devoted to sharing crucial health advice derived from the World Health Organization's safety recommendations. There will be three videos in the campaign that replay guidelines about practices such as handwashing and social distancing. "So if you suddenly come across a Creeper asking you to wash your hands, don't worry: their agenda has not permanently changed," the blog post continued. "In the game, they still want nothing more than to get cozy with you and proceed to blow up. But in our social channels, and for the time being, they also want to help put an end to the pandemic."

An anonymous reader quotes a report from The New York Times: A study released Monday by the Centers for Disease Control and Prevention shows that calls to poison hotlines this year for cases involving cleaners and disinfectants rose significantly compared with the same period over the previous two years, and charts a dramatic spike in March for both categories. Some of the physicians who collaborated on the research with the C.D.C. had discussed their observations with one another last month. "I was like: 'Am I the only one seeing a big increase in exposures to these disinfectants?'" said Dr. Diane P. Calello, the medical director of the New Jersey Poison Information and Education System, and one of the authors of the report.

Others saw the same trend, and wondered if the accidental poisonings were an insidious, secondary result of the coronavirus's spread. The group initiated the study to determine if there was a possible link between the rise in exposures and the recommendations from public health agencies to clean and disinfect as much as possible. From January through March, poison centers received 45,550 exposure calls related to cleaners (28,158) and disinfectants (17,392), the report said, representing overall increases of 20.4 percent compared with the same period in 2019 and 16.4 percent more than 2018. The authors warned that the actual number of exposures was likely even higher because the data only came from reported calls for help, and some people who were exposed probably did not report their cases to the hotlines.

LabCorp's at-home COVID-19 test, which is called 'Pixel,' has received the first Emergency Use Authorization (EUA) for such a test missed by the U.S. Food and Drug Administration (FDA). From a report: The test is an at-home collection kit, which provides sample collection materials including a nasal swab to the user, who then uses the included shipping package to return the sample to a lab for testing. Until now, the FDA has not authorized any at-home testing or sample collection kits for use, and in fact clarified its guidelines to specifically note that their use was not authorized under its guidelines when a number of startup companies debuted similar products for at-home collection and round-trip testing with labs already certified to run molecular RT-PCR tests to detect the presence of COVID-19. The FDA notes that only LabCorp's COVID-19 RT-PCR test has received this authorization, and that it still requires any such test to have an EUA before they can being offering services, whether or not the test is administered at home with the help of guidance from an authorized medical professional via telemedicine. Some labs facilitating at home serology tests using an exception in the FDA guidelines, but these are not viewed by the agency as tests that can confirm a case of COVID-19.

Space.com calls it "the first commercial satellite servicing mission." But more specifically, it's being called "the first in-orbit rendezvous and docking of two commercial satellites" in a statement from Northrop Grumman Space Systems, which also notes their "subsequent repositioning of the two-spacecraft stack." And it was all done using robotics floating 36,000km (22,369 miles) above the Earth.

Space.com describes the historic servicing of Intelsat 901 communications satellite (also known IS-901): The satellite, which launched in 2001, had been running low on fuel needed to maintain its correct orbit. But rather than launch a replacement internet satellite, its owner, Intelsat, hired Northrop Grumman to conduct a first-of-its-kind mission. That project sent another satellite, called Mission Extension Vehicle 1 (MEV-1) to connect to IS-901 in February and take responsibility for keeping the internet satellite in the proper location to do its job...

MEV-1 will now spend five years attached to IS-901 to extend that satellite's tenure. After the contract ends, MEV-1 will steer the old satellite to a safe orbit, detach, and join up with a different satellite to provide the same services. MEV-1 should be able to partner with satellites for a total of 15 years, according to a previous Northrop Grumman statement.

Northrop Grumman is planning to launch a second mission-extension vehicle later this year, which will also aid an Intelsat satellite.
Long-time Slashdot reader mi tipped us off to the story, which included a number of firsts. "Prior to this, no two commercial spacecraft had ever docked in orbit before," Ars Technica writes.

CNBC notes it also resulted in "one-of-a-kind images", since a geosynchronous satellite had never even been photographed before by another spacecraft.

CNBC reports: Microsoft is working with a consortium of pharmaceutical companies to recruit people who have recovered from Covid-19 to donate their plasma, which could be used in treatments for the disease. To help get the word out, the company is launching a chatbot, which it refers to as its "plasmabot," to lead people through a series of questions to determine if they're a candidate to donate plasma. The plasmabot, which goes live this weekend, will also provide information about the procedure and direct them to a nearby site where they can safely make the donation...

In a blog post, Microsoft says there are two possible approaches with collected plasma: Make transfusions directly available to those who are battling the virus, or incorporate the antibodies to help develop a medicine. Microsoft's head of research Peter Lee said the company is supporting the efforts of a plasma alliance formed by companies like Octapharma, Takeda, CSL Behring and others. That project kicked off in late March, and counts the Bill & Melinda Gates Foundation among its advisors.

After conducting its own research into the approach, Lee said he believes it has the "potential to save lives." So the company is setting aside computing resources and other infrastructure, as well as engineering talent. It is also promoting the plasmabot through a website, and it's search, web and social channels.

Microsoft is getting behind the effort now because plasma of recovered patients is only useful for a limited time. "There's a window from onset of symptoms that lasts from 21 to about 56 days," said Lee.
Meanwhile, a Florida newspaper reports that the Mayo Clinic is also coordinating its own study with a network of hospitals across America to "gauge the effectiveness" of plasma treatments.
