sciencehabit shares a report from Science Magazine: This month, on the frozen plains of Saskatchewan in Canada, workers began to inject steam and air into the Superb field, a layer of sand 700 meters down that holds 200 million barrels of thick, viscous oil. Their goal was not to pump out the oil, but to set it on fire -- spurring underground chemical reactions that churn out hydrogen gas, along with carbon dioxide (CO2). Eventually, the company conducting the $3 million field test plans to plug its wells with membranes that would allow only the clean-burning hydrogen to reach the surface. The CO2, and all of its power to warm the climate, would remain sequestered deep in the earth. Markets are growing for hydrogen as a fuel for power, heat, and transport, because burning it only releases water. But most hydrogen is made from natural gas, through a process that spews carbon into the air, or by electrolyzing water, which is pricey. Proton Technologies says it can cut costs by relying on oil reservoirs shunned by drillers because they are water-logged or because their oil is too thick.

Thelasko shares a report from Bloomberg: Elon Musk's SpaceX plans to spin out and pursue a public offering of its budding space-internet business Starlink, giving investors a chance to buy into one of the most promising operations within the closely held company. Space Exploration Technologies Corp. has already launched more than 240 satellites to build out Starlink, which will start delivering internet services to customers from space this summer, President Gwynne Shotwell said Thursday at a private investor event hosted by JPMorgan Chase & Co. in Miami. "Right now, we are a private company, but Starlink is the right kind of business that we can go ahead and take public," said Shotwell, SpaceX's chief operating officer. "That particular piece is an element of the business that we are likely to spin out and go public."

Investors have to this point had limited ways to own a piece of SpaceX, which has become one of the most richly valued venture-backed companies in the U.S. by dominating the commercial rocket industry. It flies satellites into orbit for customers including the U.S. military, carries cargo to the International Space Station and aims to start flying NASA astronauts and high-paying tourists soon. But the rocket-launch business remains competitive and tough. Starlink and its ability to provide high-speed internet across the globe has helped private investors in SpaceX justify a roughly $33 billion valuation. Musk has long maintained that the parent is unlikely to go public until it is regularly ferrying people to Mars.

Early signs of cancer can appear years or even decades before diagnosis, according to the most comprehensive investigation to date of the genetic mutations that cause healthy cells to turn malignant. From a report: The findings, based on samples from more than 2,500 tumours and 38 cancer types, reveal a longer-than-expected window of opportunity in which patients could potentially be tested and treated at the earliest stages of the disease. The work was carried out as part of the Pan-Cancer Analysis of Whole Genomes project, the most comprehensive study of cancer genetics to date. "What's extraordinary is how some of the genetic changes appear to have occurred many years before diagnosis, long before any other signs that a cancer may develop, and perhaps even in apparently normal tissue," said Clemency Jolly, a co-author of the research based at the Francis Crick Institute in London. "Unlocking these patterns means it should now be possible to develop new diagnostic tests that pick up signs of cancer much earlier," said Peter Van Loo, co-lead author, also of the Crick Institute. "There is a window of opportunity."

An anonymous reader quotes a report from the BBC: More than a thousand scientists have built the most detailed picture of cancer ever in a landmark study. They said cancer was like a 100,000-piece jigsaw, and that until today, 99% of the pieces were missing. Their studies, published in the journal Nature, provide an almost complete picture of all cancers. They could allow treatment to be tailored to each patient's unique tumor, or develop ways of finding cancer earlier. The Pan-Cancer Analysis of Whole Genomes Consortium analyzed the whole genetic code of 2,658 cancers.

The project found people's cancers contain, on average, between four and five fundamental mutations that drive a cancer's growth. These are potential weak-spots that can be exploited with treatments that attack these "driver mutations." However, 5% of cancers appear to have no driver mutations at all, showing there is still more work to do. Scientists also developed a way of "carbon dating" mutations. They showed that more than a fifth of them occurred years or even decades before a cancer is found. "We've developed the first timelines of genetic mutations across the spectrum of cancer types," said Dr Peter Van Loo from the Francis Crick Institute. He added: "Unlocking these patterns means it should now be possible to develop new diagnostic tests, that pick up signs of cancer much earlier." Further reading: Science Magazine

With the new coronavirus coronavirus spreading from person to person (possibly including from people without symptoms), reaching four continents, and traveling faster than SARS, driving it out of existence is looking increasingly unlikely. From a report: It's still possible that quarantines and travel bans will first halt the outbreak and then eradicate the microbe, and the world will never see 2019-nCoV again, as epidemiologist Dr. Mike Ryan, head of health emergencies at the World Health Organization, told STAT on Saturday. That's what happened with SARS in 2003. Many experts, however, view that happy outcome as increasingly unlikely. "Independent self-sustaining outbreaks [of 2019-nCoV] in major cities globally could become inevitable because of substantial exportation of pre-symptomatic cases," scientists at the University of Hong Kong concluded in a paper published in The Lancet last week. Researchers are therefore asking what seems like a defeatist question but whose answer has huge implications for public policy: What will a world with endemic 2019-nCoV -- circulating permanently in the human population -- be like?

NASA's Parker Solar Probe is healthy and operating as designed following its fourth close approach to the Sun, called perihelion, on Jan. 29. From a report: Mission controllers at the Johns Hopkins Applied Physics Laboratory in Laurel, Maryland, received a "status A" beacon from the spacecraft at 5:20 a.m. EST on Feb. 1. Status A is the best of four possible status signals, and indicates that the spacecraft is operating nominally and the instrument suites are collecting science data. This status also indicates that any minor issues that may have occurred were identified and resolved by Parker Solar Probe's onboard autonomy and fault management systems.

During this perihelion, Parker Solar Probe broke its own records for speed and proximity to the Sun for a human-made object. The spacecraft reached a speed of 244,255 miles per hour (about 393,044 kilometers per hour) as it whipped around the Sun at a distance of 11.6 million miles (about 18.6 million kilometers). Parker Solar Probe's heat shield, called the Thermal Protection System, or TPS, reached new record temperatures as well. At this distance from the Sun, computer modeling estimates show that the Sun-facing side of the TPS experienced a blazing 1,134 degrees Fahrenheit (612 degrees C), about 300 degrees hotter than encountered on the spacecraft's previous three perihelia. The spacecraft and instruments behind this protective heat shield remained at a temperature of about 85 F (30 C). During the spacecraft's closest three perihelia in 2024-25, the TPS will see temperatures around 2,500 F (1,370 C).

By exploiting randomness, three mathematicians have proved an elegant law that underlies the chaotic motion of turbulent systems. From a report: Picture a calm river. Now picture a torrent of white water. What is the difference between the two? To mathematicians and physicists it's this: The smooth river flows in one direction, while the torrent flows in many different directions at once. Physical systems with this kind of haphazard motion are called turbulent. The fact that their motion unfolds in so many different ways at once makes them difficult to study mathematically. Generations of mathematicians will likely come and go before researchers are able to describe a roaring river in exact mathematical statements. But a new proof finds that while certain turbulent systems appear unruly, they actually conform to a simple universal law. The work is one of the most rigorous descriptions of turbulence ever to emerge from mathematics. And it arises from a novel set of methods that are themselves changing how researchers study this heretofore untamable phenomenon.

"It may well be the most promising approach to turbulence," said Vladimir Sverak, a mathematician at the University of Minnesota and an expert in the study of turbulence. The new work provides a way of describing patterns in moving liquids. These patterns are evident in the rapid temperature variations between nearby points in the ocean and the frenetic, stylized way that white and black paint mix together. In 1959, an Australian mathematician named George Batchelor predicted that these patterns follow an exact, regimented order. The new proof validates the truth of "Batchelor's law," as the prediction came to be known. "We see Batchelor's law all over the place," said Jacob Bedrossian, a mathematician at the University of Maryland, College Park and co-author of the proof with Alex Blumenthal and Samuel Punshon-Smith. "By proving this law, we get a better understanding of just how universal it is."

Claudia Dreifus, writing for Quanta magazine: When I first met the immunology researcher James P. Allison in 2014, he was just becoming an icon. Columbia University had brought him to its campus to present him with the Louisa Gross Horwitz Prize for the new type of cancer therapy he had developed. Instead of trying to burn, poison or surgically remove malignant cells from the body, his treatment mobilized a patient's immune system to destroy them. During his talk at the award ceremony, Allison explained that three years earlier, the Food and Drug Administration had approved the antibody drug he had developed, ipilimumab, for use against late-stage metastatic melanoma, which is among the deadliest of cancers. Some of the terminal patients who had participated in earlier trials, he reported, had gained a decade of life. As he described how his drug had changed the prognosis for some of these patients -- it was effective for about 20% of them -- tears came to his eyes.

In all my years on a science beat, I'd never seen a researcher cry. Allison, with his long gray hair and his loose-fitting clothes, struck me as among the most interesting figures in the scientific world. Speaking with him later, I sensed that he was someone deeply original, extremely confident of his intellectual powers and unafraid to go where they took him -- the exact qualities it takes to invent a paradigm-shifting cancer treatment. Allison's drug wasn't the first or only form of immunotherapy; scientists have worked on anticancer vaccines, for example, for decades. What made Allison's "immune checkpoint therapy" unique was that it used antibodies to unlock the immune system's potential to kill cancer cells. This approach is the culmination of Allison's highly accomplished immunology career.

In the early 1980s, he identified the receptor that allows the immune system's T cells to recognize the antigens of infected or abnormal cells. A decade later, he showed that T cells also need a signal from a "costimulatory" molecule to launch their attacks. Then Allison and his colleagues discovered that a molecule called cytotoxic T lymphocyte antigen-4 (CTLA-4) acts as a checkpoint, or built-in brake, on T cells. They could remove the brake and set T cells loose against cancer cells with an antibody -- ipilimumab -- that inhibited the CTLA-4 checkpoint.

An anonymous reader quotes a report from New Atlas: New research led by Wen-Sung Chung and Justin Marshall of the University of Queensland is shedding new light on the complexity of squid brains. Using MRI scanning to examine the brain of the of the reef squid Sepioteuthis lessoniana, the researchers have produced a new map of neural connections that improves our understanding of their behavior. The cephalopods are widely recognized as the most intelligent of mollusks, but how do they rate when they are competing against something other than clams? Cephalopods show all sorts of complex behavior, like being able to recognize patterns, solve problems, communicate through signals, and camouflage themselves in different textures and colors, despite being colorblind.

But just how complex are these neural circuits? The answer may lie in the maps made by the new MRI scans. "This the first time modern technology has been used to explore the brain of this amazing animal, and we proposed 145 new connections and pathways, more than 60 percent of which are linked to the vision and motor systems," says Chung. "The modern cephalopods, a group including octopus, cuttlefish, and squid, have famously complex brains, approaching that of a dog and surpassing mice and rats, at least in neuronal number. For example, some cephalopods have more than 500 million neurons, compared to 200 million for a rat and 20,000 for a normal mollusk." "Chung says that this complexity may be an example of convergent evolution, where very distantly related animals, like dogs and squids, evolve similar solutions," the report adds. "It's why the eye of the squid is remarkably similar to that of the human eye, even though the two parted ways in evolutionary terms about 560 million years ago."

The research was published in the journal iScience.

fahrbot-bot shares a report from Phys.Org: The University of Rochester research lab that recently used lasers to create unsinkable metallic structures has now demonstrated how the same technology could be used to create highly efficient solar power generators. In a paper published in Light: Science & Applications, the lab of Chunlei Guo, professor of optics also affiliated with Physics and the Material Sciences Program, describes using powerful femto-second laser pulses to etch metal surfaces with nanoscale structures that selectively absorb light only at the solar wavelengths, but not elsewhere.

A regular metal surface is shiny and highly reflective. Years ago, the Guo lab developed a black metal technology that turned shiny metals pitch black. "But to make a perfect solar absorber," Guo says, "We need more than a black metal and the result is this selective absorber." This surface not only enhances the energy absorption from sunlight, but also reduces heat dissipation at other wavelengths, in effect, "making a perfect metallic solar absorber for the first time," Guo says. "We also demonstrate solar energy harnessing with a thermal electric generator device." "This will be useful for any thermal solar energy absorber or harvesting device," particularly in places with abundant sunlight, he adds.

sciencehabit shares a report from Science Magazine: Supermassive black holes have a reputation for consuming everything in their path, from gas clouds to entire solar systems. So is there any way aliens could live on a world that actually orbited one of these cosmic beasts? Surprisingly, the answer is a tentative yes, researchers say, although there are plenty of reasons why life could never take hold in such a place. If it did, living on such a planet would be truly surreal, with the black hole filling nearly half the sky and concentrating leftover photons from the big bang into a pseudosun. It would certainly be no place like home. The deep blackness of the event horizon, looming over nearly half the sky, would be a forbidding presence. And because of the time dilation effects in Albert Einstein's theory of gravity, known as general relativity, 1 year passing on such a planet would see thousands of years go by around an ordinary star. Even if life could take hold on such a world, there's little chance of detecting it. A planet passing in front of a black hole isn't going to make it appear any dimmer when it's black already. An expert says a vast array of radio telescopes, like the one used last year to image a black hole for the first time, might be able to detect such a transit. "Technically it's not so easy, but in theory it's possible." If this idea sounds familiar, it's because it was first published in 2017. The researchers said that in order for a planet to receive strong enough cosmic microwave background (CMB) light, it would need to orbit very close to the black hole's event horizon. However, if it were too close it would get sucked in.

"As the researchers report in The Astrophysical Journal, for their planet to get close enough, the surface of the black hole would have to spin at less than a 100-millionth of a percent shy of the speed of light," reports Science Magazine. "The black hole would also need to be large, the team calculates, at least 163 million times the Sun's mass." It would also need to be "an old galaxy" with "almost empty space" surrounding the black hole. "That's because any other stray matter being sucked into the black hole would emit a blast of radiation during its death spiral powerful enough to kill any life on a nearby planet," the report says.

A group of online archivists have created an open-access directory of over 5,000 scientific studies about coronaviruses that anyone can browse and download without encountering a paywall . From a report: The directory is hosted on The-Eye, a massive online archiving project run by a Reddit user named "-Archivist." Last week, the World Health Organization (WHO) declared a global health emergency amid the spread of the novel coronavirus beyond China, where it originated, into roughly two dozen countries so far. The organizers of the archive see their project as a resource for scientists and non-scientists alike to study the virus. "These articles were always written to be shared with as many people as possible," Reddit user "shrine," an organizer of the archive, said in a call. "From every angle that you look at it, [paywalled research] is an immoral situation, and it's an ongoing tragedy."

In 2015, Liberian public health officials co-authored a New York Times op-ed that lamented the amount of critical Ebola research that was unknown or inaccessible to scientists and health workers at the center of the 2014 epidemic. "Even today, downloading one of the papers would cost a physician here $45, about half a week's salary," the authors wrote. Shrine, who is in his late 20s, said he was inspired to assemble the archive when, last week, he clicked on a new research article about the coronavirus and encountered a $39.95 paywall. He and a few friends started to brainstorm solutions around paywalls like the one he had run into. They came up with the idea of searching for coronavirus-related papers on Sci-Hub, a free scientific research repository sometimes called "the Pirate Bay of science." Sci-Hub's site says it provides free access to over 78 million research articles by downloading HTML and PDF pages off the web, in some cases bypassing paywalls. Because of this, major scientific publishing companies -- most prominently Elsevier -- have repeatedly sued Sci-Hub for copyright infringement. Similarly, by disseminating PDFs from Sci-Hub, the coronavirus archive is in questionable legal territory.

According to a new study published in the journal Nature Geoscience, rapidly-thawing permafrost in the Arctic is causing sinkholes in a process called thermokarst. "That's the land that gets ravaged whenever permafrost thaws rapidly," reports Wired. "As the ice that holds the soil together disappears, hillsides collapse and massive sinkholes open up." From the report: Today in the journal Nature Geoscience, researchers argue that without taking abrupt thaws into account, we're underestimating the impact of permafrost thaw by 50 percent. "The amount of carbon coming off that very narrow amount of abrupt thaw in the landscape, that small area, is still large enough to double the climate consequences and the permafrost carbon feedback," says study lead author Merritt Turetsky, of the University of Guelph and University of Colorado Boulder. Less than 20 percent of northern permafrost land is susceptible to this kind of rapid thaw. Some permafrost is simply frozen rock, or even sand. But the kind we're worried about here contains a whole lot of water. "Where permafrost tends to be lake sediment or organic soils, the type of earth material that can hold a lot of water, these are like sponges on the landscape," says Turetsky. "When you have thaw, we see really dynamic and rapid changes."

That's because frozen water takes up more space than liquid water. When permafrost thaws, it loses a good amount of its volume. Think of it like thawing ice cubes made of water and muck: If you defrost the tray, the greenery will sink to the bottom and settle. "That's exactly what happens in these ecosystems when the permafrost has a lot of ice in it and it thaws,â says Turetsky. "Whatever was at the surface just slumps right down to the bottom. So you get these pits on the land, sometimes meters deep. They're like sinkholes developing in the land." "Essentially, we're taking terra firma and making it terra soupy," Turetsky adds. [...] When these lands thaw, they play host to a number of processes. As ice turns to liquid water, trees flood and die off. Thus more light reaches the soil, further accelerating thawing. This is in contrast to gradual thaw, when the plant community largely stays the same as the ice thaws. Defrosted soil at the surface gets thicker and thicker, but it doesn't catastrophically collapse.

NASA is launching a new air quality measurement tool aboard a Maxar 1300-class satellite to help improve air quality forecasting. Called "TEMPO," which stands for Tropospheric Emissions: Monitoring of Pollution, the new tool will provide hourly measurements of the levels of gases in the atmosphere over North America, including ozone, nitrogen dioxide and aerosols. TechCrunch reports: The TEMPO tool won't launch until 2022, however, which is when the Maxar satellite, called Intelsat 40e, is set to be delivered to geostationary orbit. It's not uncommon for NASA to host its scientific payloads on commercial communications satellites, providing an opportunity for NASA to effectively hitch a ride on a large geostationary satellite that'll cover the territory it wants to cover, while offering significant cost savings versus putting up a dedicated spacecraft. Ball Aerospace developed the TEMPO instrument for NASA, and it'll be transported to Maxar's Palo Alto-based satellite manufacturing facility for incorporation into the Intelsat 40e vehicle ahead of its scheduled launch. The instrument will also be used alongside other tools, including one from the European Space Agency, and South Korea's Geostationary Environment Monitoring Spectrometer, which will all combine to provide a more comprehensive and detailed picture of air quality across the northern hemisphere.

The simulators used to forecast warming have suddenly started giving us less time. From a report: There are dozens of climate models, and for decades they've agreed on what it would take to heat the planet by about 3 Celsius. It's an outcome that would be disastrous -- flooded cities, agricultural failures, deadly heat -- but there's been a grim steadiness in the consensus among these complicated climate simulations. Then last year, unnoticed in plain view, some of the models started running very hot. The scientists who hone these systems used the same assumptions about greenhouse-gas emissions as before and came back with far worse outcomes. Some produced projections in excess of 5C, a nightmare scenario.

The scientists involved couldn't agree on why -- or if the results should be trusted. Climatologists began "talking to each other like, 'What'd you get?', 'What'd you get?'" said Andrew Gettelman, a senior scientist at the National Center for Atmospheric Research in Boulder, Colorado, which builds a high-profile climate model. "The question is whether they've overshot," said Mark Zelinka, staff scientist at Lawrence Livermore National Laboratory. Researchers are starting to put together answers, a task that will take months at best, and there's not yet agreement on how to interpret the hotter results. The reason for worry is that these same models have successfully projected global warming for a half century. Their output continues to frame all major scientific, policy and private-sector climate goals and debates, including the sixth encyclopedic assessment by the UN's Intergovernmental Panel on Climate Change due out next year. If the same amount of climate pollution will bring faster warming than previously thought, humanity would have less time to avoid the worst impacts.

Thanks to the coronavirus outbreak, working from home is no longer a privilege, it's a necessity. From a report: While factories, shops, hotels and restaurants are warning about plunging foot traffic that is transforming city centers into ghost towns, behind the closed doors of apartments and suburban homes, thousands of businesses are trying to figure out how to stay operational in a virtual world. "It's a good opportunity for us to test working from home at scale," said Alvin Foo, managing director of Reprise Digital, a Shanghai ad agency with 400 people that's part of Interpublic Group. "Obviously, not easy for a creative ad agency that brainstorms a lot in person." It's going to mean a lot of video chats and phone calls, he said. The cohorts working from home are about to grow into armies. At the moment, most people in China are still on vacation for the Lunar New Year. But as Chinese companies begin to restart operations, it's likely to usher in the world's largest work-from-home experiment.

That means a lot more people trying to organize client meetings and group discussions via videochat apps, or discussing plans on productivity software platforms like WeChat Work or Bytedance's Slack-like Lark. The vanguards for the new model of scattered employees are the Chinese financial centers of Hong Kong and Shanghai, cities with central business districts that rely on hundreds of thousands of office workers in finance, logistics, insurance, law and other white-collar jobs. One Hong Kong banker said he's going to extend an overseas vacation, as he can work from anywhere with a laptop and a phone. Others say they are using the time typically spent wining and dining clients to clear their backlog of travel expenses. One said he's shifted focus to deals in Southeast Asia.

"A Russian satellite has positioned itself uncomfortably close to an American spy satellite in orbit around Earth..." reports the Verge, adding that the Russian satellite "has been in constant view of its U.S. target for nearly two weeks now."

An anonymous reader quotes The Drive: Russia has a number of what it calls "space apparatus inspectors" in orbit, which the U.S. government and others warn the Kremlin could use to gather intelligence on other satellites or function as "killer satellites," using various means to damage, disable, or destroy those targets.

On Jan. 30, 2020, Michael Thompson, a graduate student at Purdue University focusing on astrodynamics, posted a detailed thread on Twitter... [H]ow Cosmos 2542 is orbiting now means that it now has a "consistent view" of USA 245. "As I'm typing this, that offset distance shifts between 150 and 300km depending on the location in the orbit," according to Thompson....

One possibility is that it could be using onboard systems, such as cameras or other sensors, to gather information about the [U.S. satellite] KH-11, the capabilities of which are highly classified... It may also be possible to gather electronic or signals intelligence data that could be of additional value. Beyond that, the ability of Cosmos 2542 to get into this position at all is notable and is exactly the kind of orbital maneuvering that the U.S. government had pointed to in the past as evidence of potential "killer satellites." A highly maneuverable, but small satellite could possibly get close enough to disrupt the operation of, disable, or destroy another object in space using a variety of means, ranging from electronic warfare jammers to directed energy weapons, such as a laser...

Russia is known to be interested in anti-satellite capacities and has developed or is developing a number of terrestrial anti-satellite weapons, including ground-based and air-launched interceptors, too. China is pursuing similar developments, as well.


The article points out that is all happening "as the U.S. military is very publicly working to address concerns about the increasing vulnerability of various space-based systems that it relies on heavily... The most obvious expression of this recent push is the creation of U.S. Space Force, an entirely new branch of the U.S. military to focus on American military activities in and related to space, as well as the procurement of satellites and other related systems and infrastructure."

And then late Saturday night, Thompson posted another update on Twitter: that the Russian satellite had made yet another manuever on Friday, "and is now drifting back towards USA 245."

"It's been almost a year since Instagram pledged to reduce the spread of vaccine-related misinformation on its platform. But today, it continues to do the exact opposite," reports the Huffington Post: When HuffPost created a new Instagram account and searched for the term "vaccines" on Saturday, almost all of the top results were anti-vax pages... At the very top was a profile with more than 74,000 followers and posts pushing blatant falsehoods about vaccines and the Wuhan coronavirus. As soon as HuffPost followed that account, Instagram recommended dozens more that, just like it, were promoting dangerous medical misinformation amid a global health emergency.

With its 1 billion users, the role that Facebook-owned Instagram plays in shaping public discourse is not easily understated.

schwit1 quotes Space.com:
The way the fabric of space and time swirls in a cosmic whirlpool around a dead star has confirmed yet another prediction from Einstein's theory of general relativity, a new study finds.

That prediction is a phenomenon known as frame dragging, or the Lense-Thirring effect. It states that space-time will churn around a massive, rotating body. For example, imagine Earth were submerged in honey. As the planet rotated, the honey around it would swirl — and the same holds true with space-time.

Satellite experiments have detected frame dragging in the gravitational field of rotating Earth, but the effect is extraordinarily small and, therefore, has been challenging to measure. Objects with greater masses and more powerful gravitational fields, such as white dwarfs and neutron stars, offer better chances to see this phenomenon...

The researchers noted that they used frame dragging to yield insight into the rotating star that caused it. In the future, they said, they can use a similar method to analyze binary neutron stars to learn more about their internal composition, "which, even after more than 50 years of observing them, we do not yet have a handle on," study lead author Vivek Venkatraman Krishnan said. "The density of matter inside a neutron star far exceeds what can be achieved in a lab, so there is a wealth of new physics to be learnt by using this technique to double neutron-star systems."

The scientists detailed their findings online Thursday in the journal Science.

An anonymous reader quotes Reuters: Thai doctors have seen success in treating severe cases of the new coronavirus with combination of medications for flu and HIV, with initial results showing vast improvement 48 hours after applying the treatment, they said on Sunday...

"This is not the cure, but the patientâ(TM)s condition has vastly improved. From testing positive for 10 days under our care, after applying this combination of medicine the test result became negative within 48 hours," Dr. Kriangska Atipornwanich, a lung specialist at Rajavithi, told reporters.
