An anonymous reader shares a report: The predation of livestock by carnivores, and the retaliatory killing of carnivores as a result, is a major global conservation challenge. Such human-wildlife conflicts are a key driver of large carnivore declines and the costs of coexistence are often disproportionately borne by rural communities in the global south. While current approaches tend to focus on separating livestock from wild carnivores, for instance through fencing or lethal control, this is not always possible or desirable. Alternative and effective non-lethal tools that protect both large carnivores and livelihoods are urgently needed. In a new study we describe how painting eyes on the backsides of livestock can protect them from attack.

Many big cats -- including lions, leopards, and tigers -- are ambush predators. This means that they rely on stalking their prey and retaining the element of surprise. In some cases, being seen by their prey can lead them to abandon the hunt. We tested whether we could hack into this response to reduce livestock losses to lions and leopards in Botswana's Okavango delta region. This delta, in north-west Botswana, has permanent marshlands and seasonally flooded plains which host a wide variety of wildlife. It's a Unesco world heritage site and parts of the delta are protected. However, though livestock are excluded, the cordon fence is primarily intended to prevent contact and disease transmission between cattle and Cape buffalo. Large carnivores, and other wildlife including elephants, are able to move freely across it, and livestock losses to large carnivores are common in the area. In response, lethal control through shooting and poisoning can occur.

An anonymous reader quotes a report from the BBC: Apple has begun letting its iPhones carry out contact-tracing without the need for users to download an official Covid-19 app. As an alternative, owners are being invited to opt in to a scheme called Exposure Notifications Express (ENE). This keeps a 14-day log of other phones detected via Bluetooth and serves an alert if one or more of their users is later diagnosed to have the virus. The local public health authority will determine what the notification says. It might tell the user to download a more fully functional app for further guidance. However, it also gives officials the option of not developing an app of their own, in which case the user could be directed to go to a testing centre or to call a hotline for more information.

IPhone owners who become ill without having received a warning message can still cause a cascade of alerts to be sent to others. But since they will not have an app to start the process, this will be done by tapping on a text message sent by the public health authority to their smartphone after a positive diagnosis. The facility is being rolled out as part of the latest update to Apple's mobile operating system, iOS 13.7, which has just been released. Android is expected to have a similar scheme that will launch later this month. "It will go by the same name, but rather than go down the app-less route, Google has opted to automatically create a basic coronavirus tracing app for public health authorities based on the criteria they provide," reports the BBC.

"In France, a complaint is an appropriate and frequent conversation starter -- but the appropriateness of when, to whom and about what to complain is a delicate art," writes Emily Monaco via the BBC. Slashdot reader omfglearntoplay shares excerpts from the report: Many a conversation in France begins with a sigh and a lament. The French attitude towards complaining is uncomfortable for many Anglophones, many of whom argue that negativity breeds negativity. But according to some experts, the French attitude may in fact be better for your health. A 2013 study in Biological Psychiatry found that attempts to regulate negative emotions could be linked with increased risk of cardiovascular disease, while 2011 study from the University of Texas at Austin found that bottling up negative emotions can make people more aggressive. This isn't to say that complaining is always positive. Complaining too often can get you caught in a spiral, actually rewiring your brain to always focus on the negative. But French raleurs may well avoid this unfortunate side effect, in part because they rarely complain about their own lives but rather about external issues.

The latest prototype of Elon Musk's Starship prototype has only flown about 500 feet (150 meters) in the air, but the SpaceX CEO said Monday his rocket company may begin construction of a booster prototype to pair with Starship as soon as this week. CNET reports: Starship is SpaceX's platform for taking humans to the moon, Mars and beyond, but to reach those deep-space destinations, the plan is to pair Starship with a powerful first-stage booster called Super Heavy. So far we've only seen early prototypes of Starship make short test flights or "hops." Musk added that Super Heavy may have fewer engines than originally planned -- possibly 28 Raptor engines rather than 31. "That's still a lot of engines. We'll up cranking up the thrust on those engines." He mused that it might be possible for Raptor to eventually be able to lift 200 times its own weight.

As for when we might see a Starship prototype fly higher than just a hop, Musk said "probably next year" and aimed to reduce expectations a bit. "The first ones might not work," he said. "This is uncharted territory. Nobody's ever made a fully reusable orbital rocket ... and then having something twice the size of a Saturn V (the rocket that astronauts to the moon) that's also fully reusable... that's really something else, that's profound. That's the gateway to the galaxy or at least the solar system."

China continued its yearslong run of double-digit percentage increases in spending on R&D in 2019, but the nation is likely to fall short of a long-standing goal of increasing R&D expenditures to 2.5% of gross domestic product (GDP) by this year. From a report: But not hitting the target "should not be considered a failure, as China has been increasing its R&D expenditure over the past several decades at a rate higher than GDP growth," says Cao Cong, a science policy specialist at the University of Nottingham's Ningbo, China, campus. Total public and private science and technology expenditures in 2019 rose 12.5% over the previous year to 2.21 trillion Chinese yuan ($322 billion), the National Bureau of Statistics reported yesterday. Spending on basic research accounted for 6% of the total; applied research, 11.3%; and development, 82.7%. The spending amounted to 2.23% of GDP, an increase of 0.09 percentage points from the previous year. The 2.5% of GDP by 2020 goal was spelled out in China's most recent Five Year Plan and in a 15-year Medium- and Long-Term Program for Science and Technology Development. For comparison, the United States spent 2.83% of GDP on R&D in 2018, according to the 5 August Main Science and Technology Indicators of the Organisation for Economic Co-Operation and Development (OECD), which covers 37 of the world's largest national economies. OECD as a whole spent 2.38% of GDP on R&D in 2018. Israel and South Korea spent 4.9% and 4.5% of GDP, respectively, in 2018.

America's House of Representatives proposed a new structure for the U.S. Space Force in what's being called "the Starfleet amendment". Space News reports: Before the House passed the so-called "Starfleet" amendment, Space Force officials had been internally debating a new rank structure to set the space branch apart from its parent service the U.S. Air Force. The amendment in the House version of the 2021 National Defense Authorization Act requires the Space Force to use the Navy's rank structure. The proposal will be debated later this year in a House and Senate conference. The Senate would have to support the amendment for it to become law.
The amendment was introduced by a former Navy SEAL (now a Republican congressman from Texas), the article reports. But more importantly, the amendment "got a prominent endorsement from the Starfleet captain himself, William Shatner." In a special editorial in Military Times, Shatner wrote: It's been captains throughout entertainment history that have gone into space and been the heroes that saved the day, the planet, the galaxy and the universe. Where in any of this rich history of inspired heroes travelling into space was there a...colonel...?

"Star Trek" has borrowed so much of its iconic rank symbols from the U.S. military and NASA. When you unveiled the Space Force logo, many immediately saw it as an homage to "Star Trek" (even though our Delta was an homage to the previous military space insignias). Why not borrow back from "Star Trek" and adopt our ranks as well? We took them from the Navy for good reason, even though Gene Roddenberry was a veteran of the U.S. Army Air Corps. They made better sense when talking about a (space) ship.

So wrapping this up, I'm going to say that if you want the public to believe in heroes, that you should adopt the Navy ranks as they are the ones the public is most used to being heroes. So please reconsider and name the Space Force ranks after the U.S. Navy.
Space News reports that officials from Space Force "declined to comment on Shatner's article, or on whether his views might carry any weight with lawmakers." But the site's source said there's polarized feelings inside real-world Space Force about the Starfleet amendment.

"Some view the prospect of using naval ranks as an insult that would permanently turn the service into a Star Trek punchline."

The Guardian ran an article by the author of Pale Rider: The Spanish Flu of 1918 and How It Changed the World looking at problems with our own race for a vaccine in 2020: On 2 August, Steven Salzberg, a computational biologist at Johns Hopkins University in Baltimore, Maryland, suggested in Forbes magazine that a promising vaccine be rolled out to a wider pool of volunteers before clinical trials had been completed, triggering an outcry (and some sympathy) that prompted him to recant the next day. Meanwhile, a research group with links to Harvard University continues to defend its publication in July of a recipe for a do-it-yourself Covid-19 vaccine — one that only the group's 20-odd members had previously tested...

The accumulation of such incidents has left many scientists feeling deeply uneasy. "I'm more and more concerned that things are getting done in a rush," says Beate Kampmann, who directs the Vaccine Centre at the London School of Hygiene and Tropical Medicine (and whose work email account was subject to a failed hack in July). On 13 August, the editor-in-chief of the journal Science issued a call to order. "Short cuts in testing for vaccine safety and efficacy endanger millions of lives in the short term and will damage public confidence in vaccines and in science for a long time to come," wrote H Holden Thorp.

He went on to point out that the stakes are higher than with unproven therapies such as hydroxychloroquine, because a vaccine is given to healthy people. "Approval of a vaccine that is harmful or isn't effective could be leveraged by political forces that already propagate vaccine fears," he warned... Kampmann, meanwhile, feels it's important not to let the recent shenanigans in the vaccine community overshadow its huge achievements. If current forecasts are correct, a Covid-19 vaccine will be available in 2021 — smashing all records for vaccine development — and there will be many more reasons to trust it than not to. Still, those with their eye on that glittering prize should remember what is at stake. "We have to be careful," she says, "because what we do with Covid-19 could have repercussions for trust in all vaccine programs."

CNBC reports: A Texas A&M professor was charged with conspiracy, making false statements and wire fraud on allegations that he was secretly collaborating with the Chinese government while conducting research for NASA, the Department of Justice (DOJ) said Monday...

"Once again, we have witnessed the criminal consequences that can arise from undisclosed participation in the Chinese government's talent program," Assistant Attorney General for National Security John Demers said in a statement. "The Department of Justice will continue seeking to bring participation in these talent programs to light and to expose the exploitation of our nation and our prized research institutions," he added. The DOJ has previously described China's Thousand Talents Plan as a tool of the Chinese Communist Party to "attract, recruit, and cultivate high-level scientific talent in furtherance of China's scientific development, economic prosperity and national security." Through this program, the Chinese government would "often reward individuals for stealing proprietary information," the DOJ said.

"While 1.4 million foreign researchers and academics are here in the U.S. for the right reasons, the Chinese Talents Program exploits our open and free universities," said Ryan Patrick, U.S. Attorney for the Southern District of Texas, adding that ties to the Chinese government must be disclosed.
The criminal complaint accuses the professor of trying to "leverage NASA grant resources to further the research of Chinese institutions" and "gain access to the unique resources of the International Space Station."

CNET reports: Twice a year most of the U.S. stumbles around in confusion while missing appointments, resetting their clocks and grumbling about daylight saving time. The American Academy of Sleep Medicine thinks we should knock that nonsense off and just stick with standard time year-round. The AASM released a position statement this week as an accepted paper in the Journal of Clinical Sleep Medicine calling for an end to daylight saving time...

The professional organization represents sleep medicine professionals and accredits sleep medicine facilities. "Permanent, year-round standard time is the best choice to most closely match our circadian sleep-wake cycle," said lead author M. Adeel Rishi, a sleep specialist with the Mayo Clinic and vice chair of the AASM Public Safety Committee. "Daylight saving time results in more darkness in the morning and more light in the evening, disrupting the body's natural rhythm."

Studies have pointed to health risks connected to daylight saving time and the sleep disruptions it causes. The AASM called out stroke risks, stress reactions and an increase in motor vehicles crashes, particularly in relation to the springtime clock change. "Because the adoption of permanent standard time would be beneficial for public health and safety, the AASM will be advocating at the federal level for this legislative change," said AASM president Kannan Ramar in a release on Thursday.

gollum123 shared this article from MarketWatch: Do masks really work? Ask the dozens of Starbucks customers who tested positive for COVID-19 in Seoul this month after a woman with coronavirus sat under one of the cafe's air-conditioners. According to a local news report, at least 56 coronavirus cases have been linked to that one customer. The kicker: The four masked workers avoided infection...

"This speaks volumes about the role masks can play," Ma Sang Hyuk, a pediatric infectious diseases physician in South Korea, explained to Bloomberg News. "Masks may not provide 100% protection, but there's nothing out there that's as effective."

Local authorities made it mandatory this week for everybody to wear masks both indoors and outdoors, as the greater Seoul area has seen a surge in coronavirus cases.

Launching today is America's classified NROL-44 spy satellite, which German public broadcaster DW calls "a massive, open secret": NROL-44 is a huge signals intelligence, or SIGINT, satellite, says David Baker, a former NASA scientist who worked on Apollo and Shuttle missions, has written numerous books, including U.S. Spy Satellites and is editor of SpaceFlight magazine. "SIGINT satellites are the core of national government, military security satellites. They are massive things for which no private company has any purpose," says Baker... "It weighs more than five tons. It has a huge parabolic antenna which unfolds to a diameter of more than 100 meters in space, and it will go into an equatorial plane of Earth at a distance of about 36,000 kilometers (22,000 miles)," says Baker...

Spy satellites "hoover up" of hundreds of thousands of cell phone calls or scour the dark web for terrorist activity. "The move from wired communication to digital and wireless is a godsend to governments because you can't cut into wires from a satellite, but you can literally pick up cell phone towers which are radiating this stuff into the atmosphere. It takes a massive antenna, but you're able to sit over one spot and listen to all the communications traffic," says Baker...

Some people worry about congestion in space, or satellites bumping into each other, and the threat of a collision causing space debris that could damage other satellites or knock out communications networks. But that may have benefits, too — little bits of spy satellite can hide in all that mess and connect wirelessly to create a "virtual satellite," says Baker. "There are sleeper satellites which look like debris. You launch all the parts separately and disperse them into various orbits. So, you would have sensors on one bit, an amplifier on another bit, a processor on another, and they'll be orbiting relatively immersed in space debris."

"Space debris is very good for the space defense industry," says Baker, "because the more there is, the more you can hide in it."

A Nevada resident is thought to be the first person in the United States to be infected twice by the coronavirus, according to findings released this week. The New York Post reports: The 25-year-old man, of Reno, experienced a sore throat, cough, headache, nausea and diarrhea -- and first tested positive for the COVID-19 on April 18, according to a study published to the website SSRN Thursday, which has yet to be peer-reviewed. His symptoms had resolved by April 27, and he tested negative for the virus twice in May, the study says. Then on May 31, he sought treatment again for the same symptoms, in addition to a fever and dizziness, according to the study. The patient was hospitalized five days later as his symptoms worsened to include muscle aches, a cough and shortness of breath. He then tested positive for the coronavirus a second time. Another test revealed he had antibodies against the infection. A Hong Kong man was the first patient ever confirmed to be reinfected with the coronavirus. Two European cases of COVID-19 reinfection were reported one day later.

An anonymous reader quotes a report from Phys.Org: Solar cells can now be made so thin, light and flexible that they can rest on a soap bubble. The new cells, which efficiently capture energy from light, could offer an alternative way to power novel electronic devices, such as medical skin patches, where conventional energy sources are unsuitable. Until now, ultrathin organic solar cells were typically made by spin-coating or thermal evaporation, which are not scalable and which limit device geometry. This technique involved using a transparent and conductive, but brittle and inflexible, material called indium tin oxide (ITO) as an electrode. To overcome these limitations, the team applied inkjet printing. "We formulated functional inks for each the layer of the solar cell architecture," says Daniel Corzo, a Ph.D. student in Baran's team.

Instead of ITO, the team printed a transparent, flexible, conductive polymer called PEDOT:PSS, or poly(3,4-ethylenedioxythiophene) polystyrene sulfonate. The electrode layers sandwiched a light-capturing organic photovoltaic material. The whole device could be sealed within parylene, a flexible, waterproof, biocompatible protective coating. [...] After optimizing the ink composition for each layer of the device, the solar cells were printed onto glass to test their performance. They achieved a power conversion efficiency (PCE) of 4.73 percent, beating the previous record of 4.1 percent for a fully printed cell. For the first time, the team also showed that they could print a cell onto an ultrathin flexible substrate, reaching a PCE of 3.6 percent. The research has been published in the journal Advanced Materials Technologies.

Earlier today, Elon Musk demonstrated his startup Neuralink's brain link device working in a pig named Gertrude. While the science and the device itself were front-and-center at the presentation, the surgical robot the company debuted is equally as important because it's designed to handle the full surgical installation process. "That includes opening up the scalp, removing a portion of the skull, inserting the hundreds of 'thread' electrodes 6mm deep along with the accompanying chip, then closing the incision," reports CNET. TechCrunch takes a closer look at the robot: The rounded polycarbonate sci-fi design of the brain surgeon bot looks like something out of the Portal franchise, but it's actually the creation of Vancouver-based industrial design firm Woke Studio. To be clear, Musk's engineers and scientists have created the underlying technology, but Woke built the robot's look and user experience, as well as the behind-the-ear communication end piece that Neuralink has shown in prior presentations. Neuralink's bot features clean white (required for ensuring sterility, per Woke), arcing lines and smooth surfaces for a look that at once flags its advanced technical capabilities, but also contains some soothing and more approachable elements, which is wise considering what the machine is intended to do.

Woke says the Neuralink surgical robot can be separated into three main parts: The head, the body and base. The head of the robot is that helmet-like piece, which actually holds the head of the patient. It also includes a guide for the surgical needle, as well as embedded cameras and sensors to map the patent's brain. The intent of the design of this piece, which includes a mint-colored interior, is to give the robot "an anthroprmorphic characteristic" that helps distract from the invasive nature of the procedure. There are also single-use disposable bags that line the interior of the helmet for sterile operation. The Neuralink robot also has a "body," that humped rear assembly, which includes all the parts responsible for the motion of the robot as it sets up from the procedure. The third element is the base, which basically keeps the whole thing from tipping over, and apparently also contains the computing brains of the brain-bot itself.

NASA and Boeing have provided some updates around their Commercial Crew plans, which aim to get Boeing's CST-100 spacecraft certified for regular human flight. From a report: The CST-100 and Boeing's Commercial Crew aspirations hit a snag last year with a first attempt of an uncrewed orbital flight test, which did not go to plan thanks to a couple of software errors that led to an early mission ending, and a failure to reach the International Space Station as intended. In a blog post on Friday, NASA said that it and partner Boeing were aiming to fly the re-do of that uncrewed test no earlier than December 2020. This will involve flying the fully reusable Starliner CST-100 without anyone on board, in a live, fully automated simulation of how a launch with crew would go, including a rendezvous and docking with the ISS on orbit, and a return trip and controlled landing and capsule recovery. During the original OFT last December, the spacecraft took off from Cape Canaveral in Florida atop a United Launch Alliance (ULA) Atlas V as planned, but encountered an issue with its onboard mission timer shortly after disengaging from the launch vehicle. That caused it to misfire its thrusters and expend fuel, and a communication error meant that NASA was not able to correct the issue until it had used too much fuel to allow it to continue to the Space Station as planned. The capsule did safely return to Earth, however, and provided valuable test data on the way.

An anonymous reader shares a report: For every 1,000 people infected with the coronavirus who are under the age of 50, almost none will die. For people in their fifties and early sixties, about five will die -- more men than women. The risk then climbs steeply as the years accrue. For every 1,000 people in their mid-seventies or older who are infected, around 116 will die. These are the stark statistics obtained by some of the first detailed studies into the mortality risk for COVID-19. Trends in coronavirus deaths by age have been clear since early in the pandemic. Research teams looking at the presence of antibodies against SARS-CoV-2 in people in the general population -- in Spain, England, Italy and Geneva in Switzerland -- have now quantified that risk, says Marm Kilpatrick, an infectious-disease researcher at the University of California, Santa Cruz. "It gives us a much sharper tool when asking what the impact might be on a certain population that has a certain demographic," says Kilpatrick. The studies reveal that age is by far the strongest predictor of an infected person's risk of dying -- a metric known as the infection fatality ratio (IFR), which is the proportion of people infected with the virus, including those who didn't get tested or show symptoms, who will die as a result.

AmiMoJo shares a report from CNN: A type of bacteria that is highly resistant to radiation and other environmental hazards survived outside of the International Space Station for three years, according to a new study. The Japanese Tanpopo mission involved including pellets of dried Deinococcus bacteria within aluminum plates that were placed in exposure panels outside of the space station. Deinococcus bacteria is found on Earth and has been nicknamed Conan the Bacterium by scientists for its ability to survive cold, dehydration and acid. It's known as the most radiant-resistant life form in the "Guinness Book of World Records." It can resist 3,000 times the amount of radiation that would kill a human and was first isolated in cans of meat subjected to sterilizing radiation. This mission was designed to test the "panspermia" theory, which suggests that microbes can pass from one planet to another and actually distribute life. Tanpopo means dandelion in Japanese. The study has been published in the journal Frontiers in Microbiology.

nickwinlund77 shares a report from Phys.Org: A new study finds that Earth's water may have come from materials that were present in the inner solar system at the time the planet formed -- instead of far-reaching comets or asteroids delivering such water. The findings published Aug. 28 in Science suggest that Earth may have always been wet.

Researchers from the Centre de Recherches Petrographiques et Geochimiques (CRPG, CNRS/Universite de Lorraine) in Nancy, France, including one who is now a postdoctoral fellow at Washington University in St. Louis, determined that a type of meteorite called an enstatite chondrite contains sufficient hydrogen to deliver at least three times the amount of water contained in the Earth's oceans, and probably much more. Enstatite chondrites are entirely composed of material from the inner solar system -- essentially the same stuff that made up the Earth originally. "Our discovery shows that the Earth's building blocks might have significantly contributed to the Earth's water," said lead author Laurette Piani, a researcher at CPRG. "Hydrogen-bearing material was present in the inner solar system at the time of the rocky planet formation, even though the temperatures were too high for water to condense."

An anonymous reader quotes a report from NewAtlas: After an almost two-year shutdown for repairs and upgrades, CERN's Large Hadron Collider (LHC) is beginning to fire back up for its next phase of probing the mysteries of physics. Its newest particle accelerator, Linac 4, completed its first test run over the past few weeks, with the potential to provide much more energetic beams than ever before. The LHC paused operations in December 2018, beginning a massive overhaul called the High-Luminosity Large Hadron Collider (HL-LHC). When it's fully finished and finally fired up in 2026, the upgraded facility will be seven times more powerful and will collect around 10 times more data in the following decade than it did during the previous run.

And now, the first incremental stage of this upgrade is coming online. The new linear accelerator, called Linac 4, has been installed and tested over the last few weeks. This device is the starting point for accelerating protons, which are then injected into the Proton Synchrotron (PS) Booster and onto the rest of the accelerator complex. Linac 4 replaces Linac 2, which was in operation at CERN for 40 years. As you might expect the new model is significantly more powerful, injecting particles into the PS Booster at energies up to 160 MeV -- much higher than Linac 2's 50 MeV. By the time these beams are boosted, they'll reach energies of 2 GeV, compared to the 1.4 GeV that Linac 2 was capable of. This extra energy is thanks to the fact that scientists can tweak Linac 4's beams in much more detail than its predecessor.

In the three weeks up to mid-August, Linac 4 was tested with low-energy beams of negative hydrogen ions, running only through the first part of the accelerator. On August 20, it was finally cranked right up to maximum energy, with beams accelerated through the whole machine. These were then sent into a "beam dump" at the end, a device that catches and absorbs the particles.

An anonymous reader quotes a report from NewScientist: Google researchers have used a quantum computer to simulate a chemical reaction for the first time. The reaction is a simple one, but this marks a step towards finding a practical use for quantum computers. A team at Google has used the company's Sycamore device to perform the first accurate quantum simulation of a chemical reaction. Sycamore achieved quantum supremacy in 2019 when it carried out a calculation that would be impossible for a classical computer to perform in a practical amount of time. For the computer's latest feat, the researchers simulated a diazene molecule, which consists of two nitrogen atoms and two hydrogen atoms, undergoing a reaction in which the hydrogen atoms move into different configurations around the nitrogens. The quantum simulation agreed with simulations the researchers performed on classical computers to check their work. The researchers published their findings in the journal Science.
