schwit1 quotes a report from MSN: Cancer doctors fear superbugs which can't be treated with antibiotics will soon remove chemotherapy as a treatment option for their patients, a survey has revealed. Cancer patients are more vulnerable to infections because the disease and its treatments can stop the immune system from working correctly. Of the 100 oncologists in the U.K. surveyed between December 20, 2019 and February 3, 2020 by the Longitude Prize -- which was established to tackle antimicrobial resistance in cancer care -- 95 percent said they were worried about the effect superbugs could have on their patients.

An estimated one in five cancer patients need antibiotics during their treatment, according to existing research cited by the authors of the report, and cancers including multiple myeloma and acute leukemia can't be treated without them. The survey revealed that 46 percent of doctors believe drug-resistant bugs will make chemotherapy unviable. Some cancer treatments, which the report didn't name, will be obsolete in five years, 28 percent of the cancer doctors predicted. A further 39 percent forecast this would happen within the next decade, and 15 percent in two decades. Four in 10 (41 percent) said they had seen a rise in patients developing drug-resistant infections in the last year, with 23 percent of their cancer patients developing an infection during treatment on average.

As many as 65,000 cancer patients are at risk of catching a superbug infection after having surgery in the U.K. in this decade, the data suggested. Among the doctors surveyed, 5 percent of their patients who had surgery developed an infection which didn't respond to antibiotics. A total of 86 percent of the doctors said the bugs Staphylococcus, E. coli and pseudomona put cancer patients at the most risk of serious harm. The research also highlighted frustrations clinicians have with the way infections are diagnosed, with 60 percent saying laboratories take too long to identify them in their patients.

An anonymous reader shares a problem that Amazon asks in its interviews: A cable of 80 meters is hanging from the top of two poles that are both 50 meters off the ground. What is the distance between the two poles (to one decimal point) if the center cable is (a) 20 meters off the ground and (b) 10 meters off the ground?

A team of physicists at the University of Sussex has successfully developed the first nonlinear camera capable of capturing high-resolution images of the interior of solid objects using terahertz (THz) radiation. Phys.Org reports: Led by Professor Marco Peccianti of the Emergent Photonics (EPic) Lab, Luana Olivieri, Dr. Juan S. Totero Gongora and a team of research students built a new type of THz camera capable of detecting THz electromagnetic waves with unprecedented accuracy. Images produced using THz radiation are called 'hyperspectral' because the image consists of pixels, each one containing the electromagnetic signature of the object in that point.

The EPic Lab team used a single-pixel camera to image sample objects with patterns of THz light. The prototype they built can detect how the object alters different patterns of THz light. By combining this information with the shape of each original pattern, the camera reveals the image of an object as well as its chemical composition. Sources of THz radiation are very faint and hyperspectral imaging had, until now, limited fidelity. To overcome this, The Sussex team shone a standard laser onto a unique non-linear material capable of converting visible light to THz. The prototype camera creates THz electromagnetic waves very close to the sample, similar to how a microscope works. As THz waves can travel right through an object without affecting it, the resulting images reveal the shape and composition of objects in three dimensions.

Gizmodo's Ed Cara explains why HIV drugs are being used to treat the new coronavirus. An anonymous reader shares the report: On Tuesday, the Japanese government announced it will begin clinical trials to test treatments for the deadly new coronavirus that's engulfed China and spread to over two dozen countries. Rather than new drugs, they'll be studying existing medications already used to treat HIV and other viral diseases. But why exactly are researchers hopeful that these drugs can be repurposed for the new coronavirus, and how likely are they to work? The new coronavirus, recently named SARS-CoV-2 due to its close genetic ties to the SARS coronavirus, is made out of RNA. Other RNA viruses include the ones that cause Ebola, hepatitis C, and yes, HIV/AIDS.

RNA viruses come in all shapes and sizes, and those that infect humans can do so in different ways. But many of the drugs that go after HIV and the hepatitis C virus broadly target weaknesses found in all sorts of viruses. The approved hepatitis C drug ribavirin, for instance, interferes with something called the RNA-dependent RNA polymerase, an enzyme essential for many viruses -- including coronaviruses -- to produce more of themselves inside a cell. HIV drugs like lopinavir inhibit other enzymes that allow viruses to break down certain proteins, which cripples their ability to infect cells and replicate. Broad antiviral drugs like lopinavir should be able to work against SARS-CoV-2, scientists theorize. And there's already some circumstantial evidence they do. Some of these drugs have been successfully tested out for SARS and MERS, for instance, two other nasty coronaviruses that have emerged in recent years.

Slashdot readers fahrbot-bot and operator_error share a report from Phys.Org: Scientists at the University of Massachusetts Amherst have developed a device that uses a natural protein to create electricity from moisture in the air, a new technology they say could have significant implications for the future of renewable energy, climate change and in the future of medicine. As reported today in Nature, the laboratories of electrical engineer Jun Yao and microbiologist Derek Lovley at UMass Amherst have created a device they call an "Air-gen," or air-powered generator, with electrically conductive protein nanowires produced by the microbe Geobacter. The Air-gen connects electrodes to the protein nanowires in such a way that electrical current is generated from the water vapor naturally present in the atmosphere.

The new technology developed in Yao's lab is non-polluting, renewable and low-cost. It can generate power even in areas with extremely low humidity such as the Sahara Desert. It has significant advantages over other forms of renewable energy including solar and wind, Lovley says, because unlike these other renewable energy sources, the Air-gen does not require sunlight or wind, and "it even works indoors." The Air-gen device requires only a thin film of protein nanowires less than 10 microns thick, the researchers explain. The bottom of the film rests on an electrode, while a smaller electrode that covers only part of the nanowire film sits on top. The film adsorbs water vapor from the atmosphere. A combination of the electrical conductivity and surface chemistry of the protein nanowires, coupled with the fine pores between the nanowires within the film, establishes the conditions that generate an electrical current between the two electrodes. "We are literally making electricity out of thin air," says Yao. "The Air-gen generates clean energy 24/7." Lovely adds, "It's the most amazing and exciting application of protein nanowires yet."

The current generation of Air-gen devices can power small electronics, and they are expected to be brought to commercial scale soon.

SpaceX is working with Space Adventures to launch up to four tourists into a super high orbit, possible by the end of next year. "Ticket prices are not being divulged but expected to be in the millions," reports NBC Los Angeles. From the report: For this trip, paying customers will skip the space station and instead orbit two to three times higher, or roughly 500 miles to 750 miles above Earth. It's a lofty goal that would approach the record 850-mile-high orbit achieved by Gemini 11's Pete Conrad and Dick Gordon in 1966. The tourist flight "will forge a path to making spaceflight possible for all people who dream of it," SpaceX President Gwynne Shotwell said in a statement.

SpaceX will use the same kind of Dragon capsule that will launch NASA astronauts to the space station, possibly in another few months. The capsule has flown only once in space so far, making its debut last year in a successful test flight without a crew. Space Adventures spokeswoman Stacey Tearne said the tourist flight could occur in the last quarter of 2021. The company is in discussions with "several potential clients." No professional pilot or astronaut will be required, Tearne said, because the Dragon is fully autonomous. But passengers will be able to control the spacecraft if required, she said in an email.

An anonymous reader quotes a report from ZDNet: Connected medical devices are twice as likely to be vulnerable to the BlueKeep exploit than other devices on hospital networks, putting patients and staff at additional risk from cyber attacks. This is especially concerning when healthcare is already such a popular target for hacking campaigns. BlueKeep is a vulnerability in Microsoft's Remote Desktop Protocol (RDP) service which was discovered last year, and impacts Windows 7, Windows Server 2008 R2 and Windows Server 2008.

According to figures in a new report from researchers at healthcare cybersecurity company CyberMDX, 22% of all Windows devices in a typical hospital are exposed to BlueKeep because they haven't received the relevant patches. And when it comes to connected medical devices running on Windows, the figure rises to 45% -- meaning almost half are vulnerable. Connected devices on hospital networks can include radiology equipment, monitors, x-ray and ultrasound devices, anesthesia machines and more. If these devices aren't patched, it's possible that destructive cyber attacks searching for machines vulnerable to BlueKeep could put hospital networks -- and patients -- at risk. "One of the key problems for hospitals is that many devices are classed as obsolete: Windows 7, for example, is vulnerable to BlueKeep and no longer supported by Microsoft, but remains common across hospital networks," adds ZDNet. "Any further vulnerabilities uncovered in Windows 7 -- and other out-of-support operating systems -- aren't guaranteed security patches, leaving networks potentially at further risk going forward."

Many of us have an overflowing kitchen cupboard of plastic containers to store our leftovers. But as awareness grows over the health and environmental pitfalls of plastic, some consumers may be wondering: Is it time to ditch that stash of old deli containers? From a report: Only 9% of all the plastic waste ever created has been recycled. From its contributions to global heating and pollution, to the chemicals and microplastics that migrate into our bodies, the food chain and the environment, the true cost of this cheap material is becoming more apparent. There are thousands of compounds found in plastic products across the food chain, and relatively little is known about most of them. But what we do know of some chemicals contained in plastic is concerning. Phthalates, for example, which are used to make plastic more flexible and are found in food packaging and plastic wrap, have been found by the Centers for Disease Control and Prevention (CDC) in measurable levels across the US population (including in the body of Guardian journalist Emily Holden). They have been linked to reproductive dysfunction in animal studies and some researchers have suggested [PDF] links to decreased fertility, neurodevelopmental issues and asthma in humans.

BPA, another chemical widely added to food plastics and can linings, has been subject to increasing regulations after studies linked the chemical to neonatal and infant brain and reproductive harm. But BPS and BPF, two common replacements used in products marketed as "BPA-free," may have similar effects to their predecessor: studies out of both the University of Texas and Washington State University found that even at a dose of one part per trillion, BPS could disrupt cell functioning. A 2019 study from New York University linked childhood obesity with BPS and BPF. There are many other chemicals added to plastic during production, and researchers concede that many gaps remain in our understanding of how they affect health and development. But research that is adding to concerns about the "miracle material" is growing.

An anonymous reader quotes a report from The Guardian: A vending machine for powerful opioids has opened in Canada as part of a project to help fight the Canadian city's overdose crisis. The MySafe project, which resembles a cash machine, gives addicts access to a prescribed amount of medical quality hydromorphone, a drug about twice as powerful as heroin. Don Durban, a social worker from Vancouver, is one of 14 opioid addicts using the MySafe vending machine. After being prescribed opioid-based painkillers in the early 2000s, the father of two developed an addiction and now feels unable to cope without a daily dose of hydromorphone.

Unlike most addicts, Durban, 66, does not have to break the law by sourcing his fix through drug dealers. Instead he is prescribed Dilaudid -- the brand name for hydromorphone -- and, for the past couple of weeks, has been able to collect his pills from a vending machine near his home in Eastside, a rundown neighborhood with a large homeless community. "This is a godsend," he told the Guardian during one of his visits to the machine. After verifying his identity with a biometric fingerprint scan, the machine dispensed Durban with three pills for each of his four daily visits, in line with his prescription. "It means I don't have to go and buy iffy dope," he said. "I have a clean supply. I don't have to deal with other people so much. You're treated like an adult, not some kind of demonic dope fiend. We're just people with mental health issues."

Magnetic resonance imaging is no longer confined to radiology departments. The U.S. Food and Drug Administration announced this month that it has provided clearance to the "world's first" bedside MRI system, according to an announcement. From a report: Hyperfine said it will begin shipping its portable, low-field modalities this summer. It's 510(k) clearance falls on the same day that Yale researchers reported the device can accurately and safely image patient's brains for stroke. Those preliminary results are set to be presented next week at the American Stroke Association's International conference in Los Angeles, the group announced. "We've flipped the concept from having to get patients to the MRI to bringing the MRI to the patients," said Kevin Sheth, MD, senior author and a chief physician at Yale School of Medicine. "This early work suggests our approach is safe and viable in a complex clinical care environment."

The study included 85 stroke patients who underwent bedside MRI within seven days of experiencing symptoms. A majority of individuals completed the exam, which took an average of 30 minutes. Six experienced claustrophobia and a few couldn't fit into the machine, but there were no adverse events. According to Connecticut-based Hyperfine, their machine will cost $50,000, which is 20-times cheaper than traditional systems, runs on 35-times less power and weights 10 times less than normal 1.5T MRI machines.

SpaceX on Monday successfully sent another batch of Starlink satellites into orbit but didn't quite stick the landing of its Falcon 9 rocket. From a report: Elon Musk's space company did achieve its primary objective of sending 60 more flying nodes for its nascent global broadband service into space, bringing the total number of Starlink satellites in low-Earth orbit to nearly 300. A secondary goal for the fifth Starlink mission, as with most SpaceX launches, was to recover the first stage of the Falcon 9 by landing it on a droneship stationed in the Atlantic Ocean. But this time the rocket missed the mark by a smidge. At the time it was expected to land, the live webcast from the droneship showed smoke or steam just off camera as the Falcon 9 made a "soft water landing." SpaceX reported during the webcast that the rocket appears to be intact and floating on the ocean, but it remains unclear whether it can be recovered. The booster had a useful life, having already launched three earlier SpaceX missions in 2019 before Monday's Starlink mission. Had it landed successfully, it would have been the 50th successful booster landing for the company. Now we may have to wait until the next planned Falcon 9 launch on March 2 to see that milestone.

"With a renewed interest in sending humans back to the Moon and then eventually to Mars, NASA needs all the able-bodied space explorers it can get..." writes BGR.

"The requirements are, well, pretty strict, but what else would you expect from a group that sends humans into space?"

Quoting NASA.gov: Since the 1960s, NASA has selected 350 people to train as astronaut candidates for its increasingly challenging missions to explore space. With 48 astronauts in the active astronaut corps, more will be needed to crew spacecraft bound for multiple destinations and propel exploration forward as part of Artemis missions and beyond...

The basic requirements to apply include United States citizenship and a master's degree in a STEM field, including engineering, biological science, physical science, computer science, or mathematics, from an accredited institution... Candidates also must have at least two years of related, progressively responsible professional experience, or at least 1,000 hours of pilot-in-command time in jet aircraft. Astronaut candidates must pass the NASA long-duration spaceflight physical... As part of the application process, applicants will, for the first time, be required to take an online assessment that will require up to two hours to complete...

After completing training, the new astronauts could launch on American rockets and spacecraft developed for NASA's Commercial Crew Program to live and work aboard the International Space Station, 250 miles above Earth, where they will take part in experiments that benefit life at home and prepare us for more distant exploration. They may also launch on NASA's powerful new Space Launch System rocket and Orion spacecraft, docking the spacecraft at the Gateway in lunar orbit before taking a new human landing system to the Moon's surface. After returning humans to the Moon in 2024, NASA plans to establish sustainable lunar exploration by 2028. Gaining new experiences on and around the Moon will prepare NASA to send the first humans to Mars in the mid-2030s.

NASA expects to select the new class of astronaut candidates in mid-2021 to begin training as the next class of Artemis Generation astronauts.
"We're celebrating our 20th year of continuous presence aboard the International Space Station in low-Earth orbit this year..." NASA said in its statement.

Applications will be accepted from March 2nd through March 31st.

Today China announced it was taking unusual new steps to help stop the spread of the coronavirus. It's blocking the transfer of old bank notes between provinces and cities affected by the outbreak, according to the deputy governor of the People's Bank of China — and that's just the beginning.

Bloomberg reports: The central bank also ramped up measures to sanitize old money to reduce contagion risks and added 600 billion yuan ($85.9 billion) of new cash for Hubei, the epicenter of the coronavirus, he said.

"Money from key virus-hit areas will be sanitized with ultraviolet rays or heated and locked up for at least 14 days, before it is distributed again," Fan said at a press conference on Saturday. Money circulated in less riskier areas is subject to a week of quarantine and commercial lenders have been asked to separate cash from hospitals and food markets, he said.

The share of cash in broad money supply has dropped steadily in recent years in China, with the rise of mobile payments largely replacing bank notes in daily life.
"It's an extreme move that makes sense," argues Quartz: Whether it's dollars, pounds, euros, shekels, or in this case yuan, currency is notoriously dirty. A 2017 study [PDF] of $1 bills in New York found some 397 bacterial species living on the surface. And when someone with the flu handles it, that virus has been shown to survive for up to 12 days.

The World Health Organization has said that it is still not known how long the the coronavirus can survive on surfaces and objects, including money. Preliminary information has shown it can survive a few hours or more, but can be killed with basic disinfectants.

Space.com has footage of Northrop Grumman's successful launch of a spacecraft that's bringing 7,500 pounds of supplies (as well as scientific equipment for experiments) to the astronauts on the International Space Station: Those experiments include studies into bone loss from prolonged exposure to weightlessness, bacteria-targeting viruses that could lead to new medications, as well as some cowpeas to be grown as part of a space food experiment. Heidi Parris, NASA's assistant program scientist for the International Space Station program's science office, said those experiments aim to use the weightless environment on the station to learn more about how to live off Earth, including on the moon and Mars.

One novel experiment is Mochii, a small scanning electron microscope about the size of a breadbox that can help astronauts quickly identify the composition of small particles, such as debris or contamination in spacesuits. "Currently the ISS has a blind spot, in that we can't perform this kind of analysis on orbit," James Martinez, a materials scientist at NASA's Johnson Space Center participating in the experiment... Another key experiment on Cygnus is the Spacecraft Fire Experiment IV, or Saffire-IV. As its name suggests, Saffire-IV is the fourth experiment to study how fire behaves in space
Northrop Grumman's Cygnus is one of two private spacecraft (SpaceX's Dragon capsules are the other) that currently haul cargo to the International Space Station for NASA. NG-13 is the 13th Cygnus mission to reach space for NASA by Northrop Grumman as part of the agency's Commercial Resupply Services...

Northrop Grumman's Cygnus NG-13 spacecraft will arrive at the International Space Station and be captured by a robotic arm on Tuesday, Feb. 18, at 4 a.m. EST (0900 GMT). NASA's live webcast of the rendezvous will begin at 2:30 a.m. EST (0730 GMT) and run through spacecraft capture.
The spacecraft will also be bringing the astronauts candy, fresh fruit, and three different kinds of cheese wedge -- cheddar, Parmesan and Fontina.

schwit1 shared this report from Ars Technica: This is a consequential hire for SpaceX — it is difficult to overstate the influence Gerstenmaier has over human spaceflight both in the United States and abroad. He led NASA's space shuttle, International Space Station, commercial crew, and exploration programs for more than a decade. He immediately brings credibility to the company's safety culture. Former Space Shuttle Program Manager Wayne Hale, who now chairs the human spaceflight committee of NASA's Advisory Council, told Ars last summer, "Bill was recognized by everybody as being technically well-grounded and very astute. He was known to listen carefully and to make his judgments based on good technical reasons...."

Although the role is officially a consultancy, it is expected to become a full-time position. SpaceX is poised to launch the first crewed mission of its Dragon spacecraft by June of this year. [Or possibly even in early May.] Gerstenmaier will play a key role in ensuring the safety of those missions and helping SpaceX secure certification for the Crew Dragon vehicle. The hiring could have longer-term implications as well. Few people in the global aerospace community have as much gravitas as Gerstenmaier or as much understanding of how to build coalitions to explore space...

In December 2008, Gerstenmaier saved a cash-strapped SpaceX with a Commercial Resupply Service contract for operational cargo missions to the International Space Station. Gerstenmaier's decision to maintain two competitors as part of the commercial crew program in 2014 (SpaceX and Boeing) was also essential, although it was not a company-saving move. Boeing was lobbying hard for all of the funds and very nearly got them. Gerstenmaier was the deciding official who kept two providers in the competition. It has proven to be a smart decision, as SpaceX is poised to beat Boeing into space by months, if not years, at 50 percent less cost.

An anonymous reader quotes a report from Ars Technica: A 3D model is sliced up into hundreds of 2D horizontal layers and slowly built up, one layer at a time. This layer-by-layer process can take hours or even days, but what if we could print the entire model at once? A new technique demonstrated by researchers from Switzerland's Ecole polytechnique federale de Lausanne (EPFL) -- and further detailed in this Nature article -- does just that and can print an entire model in seconds. The new technique builds a model by hardening a photosensitive resin with a laser, not unlike existing stereolithography (SLA) printers. The big difference here is the application of tomographic techniques, the same used in x-rays and ultrasounds, that allows for rotational printing. Laser light is modulated with a DLP chip (just like in old rear-projection HDTVs) and is blasted into a container full of resin. The laser covers the entire build volume, and the container of resin actually rotates while it's being exposed to the light. The laser projects the model at different rotational perspectives, which is synced up with the spinning resin, and a whole 3D model can be produced in seconds.

The EPFL writes, "The system is currently capable of making two-centimeter structures with a precision of 80 micrometers, about the same as the diameter of a strand of hair. But as the team develops new devices, they should be able to build much bigger objects, potentially up to 15 centimeters." In this first public demonstration, the build volume is 16mm x 16mm x 20mm, making it one of the smallest 3D printers on earth. An 80 um resolution is also nothing to write home about and can be bested by ~$500 consumer SLA printers. It is very fast, though, and the technique is just getting started. The researchers have set up a spin-off company called "Readily 3D" to develop and market the technology.

cusco shares a report: For the 30th anniversary of one of the most iconic views from the Voyager mission, NASA's Jet Propulsion Laboratory in Pasadena, California, is publishing a new version of the image known as the "Pale Blue Dot." The updated image uses modern image-processing software and techniques while respecting the intent of those who planned the image. Like the original, the new color view shows Planet Earth as a single, bright blue pixel in the vastness of space. Rays of sunlight scattered within the camera optics stretch across the scene, one of which happens to have intersected dramatically with Earth.

The view was obtained on Feb. 14, 1990, just minutes before Voyager 1's cameras were intentionally powered off to conserve power and because the probe -- along with its sibling, Voyager 2 -- would not make close flybys of any other objects during their lifetimes. Shutting down instruments and other systems on the two Voyager spacecraft has been a gradual and ongoing process that has helped enable their longevity. This celebrated Voyager 1 view was part of a series of 60 images designed to produce what the mission called the "Family Portrait of the Solar System." This sequence of camera-pointing commands returned images of six of the solar system's planets, as well as the Sun. The Pale Blue Dot view was created using the color images Voyager took of Earth. Planetary scientist Carolyn Porco shared the story behind the idea of Pale Blue Dot picture on Neil deGrasse Tyson's video podcast "Star Talk" last year. It's fascinating -- watch from 51:05 seconds and hang around for 13 minutes. Also the famous video where Carl Sagan describes the Pale Blue Dot. An interview he did on the subject later.

The rise of preprint repositories has helped scientists worldwide to share results and get feedback quickly. But several platforms that serve researchers in emerging economies are struggling to raise money to stay afloat. One, which hosts research from Indonesia, has decided to close because of this funding shortfall. From a report: INA-Rxiv, which was set up in 2017, was one of the first repositories to host studies from a particular region. Previous platforms served specific disciplines: for example, arXiv, the original preprint repository, hosts physical-sciences research, and bioRxiv is a popular repository for biology studies. Other region or language-specific repositories followed, including ArabiXiv, which hosts Arabic-language research; AfricArxiv and IndiaRxiv. Managers of these repositories say they increase exposure for research from the regions, and facilitate collaborations. INA-Rxiv, ArabiXiv, AfricArxiv and IndiaRxiv are run by volunteers around the world, but the servers are hosted online by the non-profit Center for Open Science (COS), based in Charlottesville, Virginia. The centre's platform hosts 26 repositories, including more than a dozen that are discipline-specific. In December 2018, the COS informed repository managers that from 2020, it would be introducing fees, charged to repository managers, to cover maintenance costs. The charges, which were finalized last December, start at about US$1,000 a year, and increase as repositories' annual submissions grow. The costs can be significant, particularly for repositories run by volunteers in emerging economies.

Meghan Bartels writes via Space.com: One of Earth's premier instruments for studying nearby asteroids is back to work after being rattled by earthquakes, and its first new observations show that a newly discovered space rock is actually two separate asteroids. The instrument is the planetary radar system at the Arecibo Observatory in Puerto Rico. The observatory was closed for most of January, after a series of earthquakes hit the island beginning on Dec. 28, 2019. The observatory reopened on Jan. 29. Meanwhile, on Jan. 27, scientists using a telescope on Mauna Loa in Hawaii spotted an asteroid that astronomers hadn't seen before. The team dubbed the newfound space rock 2020 BX12 based on a formula recognizing its discovery date.

Because of the size of 2020 BX12 and the way its orbit approaches that of Earth, it is designated a potentially hazardous asteroid. However, the space rock has already come as close to Earth as it will during this pass (2.7 million miles or 4.3 million kilometers); astronomers have calculated the asteroid's close approaches with Earth for the next century, and all will be at a greater distance than this one was. [...] Based on the observations, the scientists discovered that 2020 BX12 is a binary asteroid, with a smaller rock orbiting the larger rock. About 15% of larger asteroids turn out, on closer inspection, to be binary, according to NASA. The larger rock is likely at least 540 feet (165 meters) across, and the smaller one is about 230 feet (70 m) wide, according to the observations gathered by Arecibo. When the instrument observed the two space rocks on Feb. 5, they appeared to be separated by about 1,200 feet (360 m).

An anonymous reader quotes a report from The Guardian: Two scientific studies of the number of insects splattered by cars have revealed a huge decline in abundance at European sites in two decades. The survey of insects hitting car windscreens in rural Denmark used data collected every summer from 1997 to 2017 and found an 80% decline in abundance. It also found a parallel decline in the number of swallows and martins, birds that live on insects.

The second survey, in the UK county of Kent in 2019, examined splats in a grid placed over car registration plates, known as a "splatometer." This revealed 50% fewer impacts than in 2004. The research included vintage cars up to 70 years old to see if their less aerodynamic shape meant they killed more bugs, but it found that modern cars actually hit slightly more insects. [...] The stream research, published in the journal Conservation Biology, analyzed weekly data from 1969 to 2010 on a stream in a German nature reserve, where the only major human impact is climate change. "Overall, water temperature increased by 1.88C and discharge patterns changed significantly. These changes were accompanied by an 81.6% decline in insect abundance," the scientists reported. "Our results indicate that climate change has already altered [wildlife] communities severely, even in protected areas."
