An anonymous reader quotes a report from ScienceAlert: [A] team of surgeons has successfully completed the first human implantation in the US of an artificial heart device called the 'Aeson', developed by French company CARMAT. The artificial heart has two ventricular chambers and four biological valves, just like the real organ, and is powered by an external device. Made from "biocompatible materials" including bovine tissue, the artificial heart uses a combination of sensors and algorithms to maintain its pace and keep blood circulating through the body. "We are encouraged that our patient is doing so well after the procedure," says cardiologist Carmelo Milano from the Duke University School of Medicine. "As we evaluate this device, we are both excited and hopeful that patients who otherwise have few to no options could have a lifeline."

The patient in question is 39-year-old Matthew Moore, from Shallotte in North Carolina. Moore was initially due to have heart bypass surgery, but as his condition deteriorated the medical staff started to run out of options; he became so ill that even a regular heart transplant was too risky. Fortunately, he was in the right place: the Aeson device is being tested at Duke University, pending approval from the US Food and Drug Administration (FDA). It's already been given the green light for use by regulators in Europe, after several years of tests in European patients, not all of which have been successful. The artificial heart has been developed specifically to help those whose hearts can no longer pump enough blood through both chambers. It replaces the entire natural heart, although it's not intended to be permanent -- it's designed to be a bridge towards a full heart transplant within six months or so.

An anonymous reader quotes a report from Ars Technica: Just one week after Google's DeepMind AI group finally described its biology efforts in detail, the company is releasing a paper that explains how it analyzed nearly every protein encoded in the human genome and predicted its likely three-dimensional structure -- a structure that can be critical for understanding disease and designing treatments. In the very near future, all of these structures will be released under a Creative Commons license via the European Bioinformatics Institute, which already hosts a major database of protein structures. In a press conference associated with the paper's release, DeepMind's Demis Hassabis made clear that the company isn't stopping there. In addition to the work described in the paper, the company will release structural predictions for the genomes of 20 major research organisms, from yeast to fruit flies to mice. In total, the database launch will include roughly 350,000 protein structures.
[...]
At some point in the near future (possibly by the time you read this), all this data will be available on a dedicated website hosted by the European Bioinformatics Institute, a European Union-funded organization that describes itself in part as follows: "We make the world's public biological data freely available to the scientific community via a range of services and tools." The AlphaFold data will be no exception; once the above link is live, anyone can use it to download information on the human protein of their choice. Or, as mentioned above, the mouse, yeast, or fruit fly version. The 20 organisms that will see their data released are also just a start. DeepMind's Demis Hassabis said that over the next few months, the team will target every gene sequence available in DNA databases. By the time this work is done, over 100 million proteins should have predicted structures. Hassabis wrapped up his part of the announcement by saying, "We think this is the most significant contribution AI has made to science to date." It would be difficult to argue otherwise.

Last year the artificial intelligence group DeepMind cracked a mystery that has flummoxed scientists for decades: stripping bare the structure of proteins, the building blocks of life. Now, having amassed a database of nearly all human protein structures, the company is making the resource available online free for researchers to use. From a report: The key to understanding our basic biological machinery is its architecture. The chains of amino acids that comprise proteins twist and turn to make the most confounding of 3D shapes. It is this elaborate form that explains protein function; from enzymes that are crucial to metabolism to antibodies that fight infectious attacks. Despite years of onerous and expensive lab work that began in the 1950s, scientists have only decoded the structure of a fraction of human proteins.

DeepMind's AI program, AlphaFold, has predicted the structure of nearly all 20,000 proteins expressed by humans. In an independent benchmark test that compared predictions to known structures, the system was able to predict the shape of a protein to a good standard 95% of time. DeepMind, which has partnered with the European Molecular Biology Laboratory's European Bioinformatics Institute (EMBL-EBI), hopes the database will help researchers to analyse how life works at an atomic scale by unpacking the apparatus that drives some diseases, make strides in the field of personalised medicine, create more nutritious crops and develop "green enzymes" that can break down plastic.

UnknowingFool shares a report from CBS News: After being down for a month due to a computer issue, Hubble was brought back up last week. NASA released images captured by Hubble over the weekend including a rare observance of two galaxies that are colliding. The other interesting image is that of a spiral galaxy with three arms, as most spiral galaxies have an even number of arms. "I'm thrilled to see that Hubble has its eye back on the universe, once again capturing the kind of images that have intrigued and inspired us for decades," NASA administrator Bill Nelson said in a statement. "This is a moment to celebrate the success of a team truly dedicated to the mission. Through their efforts, Hubble will continue its 32nd year of discovery, and we will continue to learn from the observatory's transformational vision."

turp182 shares a report from USA Today: [T]he UAE is now testing a new method that has drones fly into clouds to give them an electric shock to trigger rain production [...]. The project is getting renewed interest after the UAE's National Center of Meteorology recently published a series of videos on Instagram of heavy rain in parts of the country. Water gushed past trees, and cars drove on rain-soaked roads. The videos were accompanied by radar images of clouds tagged "#cloudseeding." The Independent reports recent rain is part of the drone cloud seeding project.

The UAE oversaw more than 200 cloud seeding operations in the first half of 2020, successfully creating excess rainfall, the National News reported. There have been successes in the U.S., as well as China, India, and Thailand. Long-term cloud seeding in the mountains of Nevada have increased snowpack by 10% or more each year, according to research published by the American Meteorological Society. A 10-year cloud seeding experiment in Wyoming resulted in 5-10% increases in snowpack, according to the State of Wyoming. According to a researcher that worked on the drone initiative, "the aim of the UAE's project is to change the balance of electrical charge on the cloud droplets, causing water droplets to clump together and fall as rain when they are big enough."

The world's largest carbon capture and storage project has failed to meet a crucial target of capturing and burying an average of 80% of the carbon dioxide produced from gas wells in Western Australia over five years. From a report: The energy giant Chevron agreed to the target with the West Australian government when developing its $54 billion Gorgon project to extract and export gas from fields off the WA coast. The five year milestone passed on Sunday. In a statement the energy giant Chevron announced that since operations began in August 2019 it had injected five million tonnes of greenhouse gases underground. According to the independent analyst Peter Milne, that leaves a shortfall of around 4.6 million tonnes, which he estimates would cost about $100 million to offset via carbon credits.

The project has national and even international significance, with the oil and gas industry and the federal government declaring the success of carbon capture and storage to be crucial in tackling climate change while making use of fossil fuels. "It is essential we position Australia to succeed by investing now in the technologies that will support our industries into the future, with lower emissions energy that can support Australian jobs," Prime Minister Scott Morrison said in April while announcing $263.7 million in funding to develop carbon capture and storage technology.

An anonymous reader quotes a report from Ohio State News: Scientists who study glacier ice have found viruses nearly 15,000 years old in two ice samples taken from the Tibetan Plateau in China. Most of those viruses, which survived because they had remained frozen, are unlike any viruses that have been cataloged to date. The findings, published today in the journal Microbiome, could help scientists understand how viruses have evolved over centuries. For this study, the scientists also created a new, ultra-clean method of analyzing microbes and viruses in ice without contaminating it.

The researchers analyzed ice cores taken in 2015 from the Guliya ice cap in western China. The cores are collected at high altitudes -- the summit of Guliya, where this ice originated, is 22,000 feet above sea level. The ice cores contain layers of ice that accumulate year after year, trapping whatever was in the atmosphere around them at the time each layer froze. Those layers create a timeline of sorts, which scientists have used to understand more about climate change, microbes, viruses and gases throughout history. Researchers determined that the ice was nearly 15,000 years old using a combination of traditional and new, novel techniques to date this ice core. When they analyzed the ice, they found genetic codes for 33 viruses. Four of those viruses have already been identified by the scientific community. But at least 28 of them are novel. About half of them seemed to have survived at the time they were frozen not in spite of the ice, but because of it.

An anonymous reader quotes a report from CNBC: Jeff Bezos has heard the complaints about billionaires like himself funneling their money into private rocket companies instead of donating to causes on Earth, and he doesn't disagree. In an interview with CNN ahead of his planned Tuesday morning space voyage in a rocket built by his company Blue Origin, Bezos was asked for his thoughts on critics who call the extraterrestrial flights "joyrides for the wealthy, and [who say] you should be spending your time and your money and energy trying to solve problems here on Earth." "Well, I say they are largely right," said Bezos, who Bloomberg estimates is worth $206 billion. "We have to do both. We have lots of problems here on Earth and we have to work on those."

Bezos and fellow billionaires [...] have been characterized by critics as deaf to issues on the ground and too obsessed with making space more accessible when they could put their resources elsewhere. The 57-year-old Bezos, who earlier this month stepped down as CEO of Amazon, said it's important to "look to the future ... as a species and as a civilization." In his view, the work being done today will lay the foundation for future generations to work in space, which "will solve problems here on Earth." In an opinion piece for MSNBC, Talia Lavin views billionaires going to space through a more incendiary lens, writing: "What they seek to leave behind is a planet burning and flooding and full of the kind of small and ordinary suffering such fortunes could alleviate in an instant."

The space program of the 1960s, which resulted in the first crewed mission to land on the Moon, "may have been mired in the bitter and petty rivalries of the Cold War, and limned by prejudice about who could excel," writes Lavin, "but it was a project funded and created by our government, an achievement held in common by the masses. No such common pride can be held in the launch of the titans of capital."

"In this billionaire battle, there is no pretense at a sense of collective pride or communal achievement. Even the drumbeat of nationalism would be better than this obscene egotism, whose fumes are more putrid than rocket-jet emissions. It feels like a parody of hubris, and a colossal celebration of the social failure to moderate preposterous accumulations of wealth."

Thoughts?

Aerospace companies have launched about 2,000 Internet satellites into orbit around Earth over the past 2 years, nearly doubling the number of active satellites. This has sparked concerns among astronomers and other skygazers, who worry about interference with observations of the night sky. From a report: Now, in what would be the biggest international step yet towards addressing these concerns, diplomats at a United Nations forum next month might discuss whether humanity has a right to 'dark and quiet skies.' The debate could initiate a framework for how scientists and the public would deal with the flood of new satellites -- with many more expected.

Tens of thousands of satellites could be added to Earth orbit in the next few years to provide broadband Internet, if companies and governments build and launch all the networks, or 'megaconstellations,' they have publicly announced. The sheer number of these could mean that hundreds are visible all night long, affecting the sky like never before in human history. "These constellations are changing dramatically the way space has been used," says Piero Benvenuti, an astronomer at the University of Padua in Italy and a former general secretary of the International Astronomical Union (IAU). He and other astronomers have been working through the IAU to raise international awareness of how the megaconstellations are affecting scientists and members of the public. They say the goal is not to pit astronomers against satellite companies, but to develop a vision of how to fairly use the shared realm of outer space.

Another scorching summer heat wave was set to peak across portions of the western United States early this week, with air so dry that rain from thunderstorms evaporated before reaching the ground and smoke from wildfires delayed hundreds of flights at one of the region's largest airports. From a report: Temperatures reached the upper 90s and lower 100s in parts of the Northern Rockies on Monday, and forecasters warned of "dry thunderstorms," which bring lightning that can spark fires, but no rain to quench them. It was the fourth major heat wave to afflict parts of the West since early June, bringing dangerously hot temperatures and helping fuel the deepening drought and exploding wildfires across the region. An excessive heat warning was also in effect for parts of Montana and Wyoming through Thursday, the National Weather Service said.

Glasgow, a town in northern Montana, hit 110 degrees on Monday, the Weather Service said. By 2:45 p.m. local time, Billings, toward the southern portion of the state, was officially hotter than Death Valley, Calif., at 110.4 degrees. Weather officials in Billings took advantage of the toasty temperatures and baked a batch of cookies on the dashboard of a car. "It may have taken 5 hours but we have fully baked cookies," they shared on Twitter. Lander, in central Wyoming, reached a record 100 degrees on Monday, according to the Weather Service. In 130 years, it was only the 21st day in Lander to reach triple digits. Parts of Idaho, including Boise and Twin Falls, saw much needed rain showers.

NPR: Wearing a cowboy hat under the West Texas morning sun, Jeff Bezos crossed the bridge to enter the capsule made by his company Blue Origin. He was accompanied by three others -- his brother Mark Bezos, female aviation pioneer Wally Funk and 18-year-old Oliver Daemen. Then the shuttle hatch closed and just before 9:15 a.m. ET, the four blasted into space on the first human flight on Blue Origin's New Shepard launch vehicle. Bezos is the second billionaire this month to reach the edge of space: Richard Branson rocketed there last week aboard a vessel made by his company Virgin Galactic. The date of the New Shepard's maiden launch is no accident: July 20 was the day in 1969 that Neil Armstrong and Buzz Aldrin landed on the moon. Further reading: 'Mercury 13' pilot Wally Funk carried 60 years of history to space on Blue Origin flight.

An anonymous reader quotes a report from Interesting Engineering: [Researchers at the Indian Institute of Science Education and Research (IISER), Kolkata] along with those at the Indian Institute of Technology (IIT), Kharagpur decided to focus on developing something that is harder than conventional self-healing material, as reported by The Telegraph India. The researchers used a piezoelectric organic material, which converts mechanical energy to electrical energy and vice versa, to make needle-shaped crystals that aren't more than 2 mm long or 0.2 mm wide, according to the experimental results which were published in the journal Science. Due to their molecular arrangement in the specially designed crystals, a strong attractive force developed between two surfaces. Every time a fracture occurred, the attractive forces joined the pieces back again, without needing an external stimulus such as heat or others that most self-healing materials would need.

"Our self-healing material is 10 times harder than others, and it has a well-ordered internal crystalline structure, that is favored in most electronics and optical applications," lead researcher Professor Chilla Malla Reddy of IISER said. "I can imagine applications for an everyday device," said Bhanu Bhushan Khatua, a member of the team from IIT Kharagpur." Such materials could be used for mobile phone screens that will repair themselves if they fall and develop cracks."

fahrbot-bot shares a report from Live Science: Imagine a universe where you could point a spaceship in one direction and eventually return to where you started. If our universe were a finite donut, then such movements would be possible and physicists could potentially measure its size. "We could say: Now we know the size of the universe," astrophysicist Thomas Buchert, of the University of Lyon, Astrophysical Research Center in France, told Live Science in an email.

Examining light from the very early universe, Buchert and a team of astrophysicists have deduced that our cosmos may be multiply connected, meaning that space is closed in on itself in all three dimensions like a three-dimensional donut. Such a universe would be finite, and according to their results, our entire cosmos might only be about three to four times larger than the limits of the observable universe, about 45 billion light-years away.

18-year-old Oliver Daemon will become the youngest person ever to travel to space as the fourth passenger on Blue Origin's first crewed mission this week to the edge of outer space (flying with Jeff Bezos, his brother Mark, and 82-year-old aviator Wally Funk).

The Atlantic calls it "a rather unusual bunch": When they take off on Tuesday, they will each fulfill a personal dream, but as a crew, they're making history: No group like this one has ever gone to space together before. Even the participants of the most diverse missions to the International Space Station have had far more in common with one another than this quartet. They were all professional astronauts, with comparable ages, educational backgrounds, and even temperaments, given that potential astronauts must undergo psychological screenings before getting the job. The motley crew of Blue Origin's first passenger flight seems closer to a cast of offbeat characters gathered together for a zany adventure: If The Breakfast Club had the brain, the jock, the basket case, the princess, and the criminal, this Blue Origin flight has the boss, the tag-along, the real deal, and the kid...

Blue Origin has conducted 15 test flights of the New Shepard rocket, but has never before flown the vehicle with people on board.

Of the passengers on Bezos's debut flight, Daemen might be the most unexpected pick. In fact, Daemen wasn't supposed to be on this flight. Blue Origin had held an auction for one of the seats on the flight, culminating in a top bid of a whopping $28 million. But the company said today that the winner, whose name has not been disclosed, decided to skip this particular flight and go later, citing "scheduling conflicts," so the company slotted in Daemen, a soon-to-be physics student at Utrecht University, in the Netherlands. (Blue Origin said the teen was "a participant in the auction," but did not disclose how much the seat cost.)

Daemen and Funk, as Blue Origin pointed out in its announcement, "represent the youngest and oldest astronauts to travel to space." But describing them by age alone elides the very different journeys they have taken to reach this point. Funk is an aviation legend who underwent more difficult tests than John Glenn, the first American to orbit the Earth, had to, and has waited 60 years for this moment. Daemen is a teenager who took a gap year to get his pilot's license, and the son of a private-equity executive... Daemen represents a new class of spacefarers; in the coming years, as private companies such as Blue Origin, Richard Branson's Virgin Galactic, and Elon Musk's SpaceX make people into astronauts more readily than government agencies like NASA can, the distance between a childhood dream and reality is bound to shrink. Expect more smorgasbord space crews like the Blue Origin one, filled with an assortment of very wealthy individuals and the people they choose to go with them...

The rules about who can become an astronaut have changed, and the new "right stuff" is money and luck.

Slashdot reader sciencehabit shares news from Science magazine: When a giant space rock struck the waters near Mexico's Yucatán Peninsula 66 million years ago, it sent up a blanket of dust that blotted out the Sun for years, sending temperatures plummeting and killing off the dinosaurs. The impact also generated a tsunami in the Gulf of Mexico that some modelers believe sent an initial tidal wave up to 1500 meters (or nearly 1 mile) high crashing into North America, one that was followed by smaller pulses.

Now, for the first time, scientists have discovered fossilized megaripples from this tsunami buried in sediments in what is now central Louisiana.

"It's great to actually have evidence of something that has been theorized for a really long time," says Sean Gulick, a geophysicist at the University of Texas, Austin. Gulick was not involved in the work, but he co-led a campaign in 2016 to drill down to the remains of the impact crater, called Chicxulub... Cores from the 2016 drilling expedition helped explain how the impact crater was formed and charted the disappearance and recovery of Earth's life. In 2019, researchers reported the discovery of a fossil site in North Dakota, 3000 kilometers north of Chicxulub, that they say records the hours after the impact and includes debris swept inland from the tsunami.

"We have small pieces of the puzzle that keep getting added in," says Alfio Alessandro Chiarenza, a paleontologist at the University of Vigo who was not involved with the new study. "Now this research is another one, giving more evidence of a cataclysmic tsunami that probably inundated [everything] for thousands of miles."

"China conducted a clandestine first test flight of a reusable suborbital vehicle Friday as a part of development of a reusable space transportation system," reports Space News:

The vehicle launched from the Jiuquan Satellite Launch Center Friday and later landed at an airport just over 800 kilometers away at Alxa League in Inner Mongolia Autonomous Region, the China Aerospace Science and Technology Corp. (CASC) announced. No images nor footage nor further information, such as altitude, flight duration or propulsion systems, were provided. The CASC release stated however that the vehicle uses integrated aviation and space technologies and indicates a vertical takeoff and horizontal landing profile.

The test follows a September 2020 test flight of a "reusable experimental spacecraft". The spacecraft orbited for days, releasing a small transmitting payload and later deorbited and landed horizontally. The spacecraft is widely believed to be a reusable spaceplane concept, though no images have emerged. Giant space and defense contractor CASC also developed that vehicle and stated that the new vehicle tested Friday can be used as a first stage of a reusable space transportation system. The implication is that the two vehicles will be combined for a fully reusable space transportation system. The developments have not come out of the blue. China stated in 2017 that it aimed to test a reusable spaceplane in 2020...

Chen Hongbo, from CASC's China Academy of Launch Vehicle Technology (CALT), told Science and Technology Daily (Chinese) in 2017 that the reusable spacecraft would be capable of carrying both crew and payloads... Chen stated the aim was full reusability, moving beyond partial reusability of Falcon 9-like launchers. The spaceplane, the development and testing of which is to be completed by 2030, should be capable of being reused more than 20 times.

"The efficacy of a drug being promoted by rightwing figures worldwide for treating Covid-19 is in serious doubt," reports the Guardian, "after a major study suggesting the treatment is effective against the virus was withdrawn due to 'ethical concerns'." The preprint study on the efficacy and safety of ivermectin — a drug used against parasites such as worms and headlice — in treating Covid-19, led by Dr Ahmed Elgazzar from Benha University in Egypt, was published on the Research Square website in November. It claimed to be a randomised control trial, a type of study crucial in medicine because it is considered to provide the most reliable evidence on the effectiveness of interventions due to the minimal risk of confounding factors influencing the results...

A medical student in London, Jack Lawrence, was among the first to identify serious concerns about the paper, leading to the retraction... He found the introduction section of the paper appeared to have been almost entirely plagiarised. It appeared that the authors had run entire paragraphs from press releases and websites about ivermectin and Covid-19 through a thesaurus to change key words. "Humorously, this led to them changing 'severe acute respiratory syndrome' to 'extreme intense respiratory syndrome' on one occasion," Lawrence said.

The data also looked suspicious to Lawrence... "In their paper, the authors claim that four out of 100 patients died in their standard treatment group for mild and moderate Covid-19," Lawrence said. "According to the original data, the number was 0, the same as the ivermectin treatment group. In their ivermectin treatment group for severe Covid-19, the authors claim two patients died, but the number in their raw data is four..." Lawrence contacted an Australian chronic disease epidemiologist from the University of Wollongong, Gideon Meyerowitz-Katz, and a data analyst affiliated with Linnaeus University in Sweden who reviews scientific papers for errors, Nick Brown, for help analysing the data and study results more thoroughly... "The main error is that at least 79 of the patient records are obvious clones of other records," Brown told the Guardian. "It's certainly the hardest to explain away as innocent error, especially since the clones aren't even pure copies. There are signs that they have tried to change one or two fields to make them look more natural..."

Meyerowitz-Katz told the Guardian that "this is one of the biggest ivermectin studies out there", and it appeared to him the data was "just totally faked".
Meta-analyses incorporating the "just totally faked" data were then published in Oxford Academic's Open Forum Infectious Diseases and in the American Journal of Therapeutics.

Meanwhile, the Guardian also notes a new (and peer-reviewed) paper that was just published last month in the journal Clinical Infectious Diseases. Its finding? Iermectin is "not a viable option to treat COVID-19 patients".

"Since Joe Biden took office [in January], about two dozen U.S. intelligence officers, diplomats, and other government officials in Vienna have reported experiencing mysterious afflictions similar to the Havana Syndrome," reports the New Yorker: U.S. officials say the number of possible new cases in the Austrian capital — long a nexus of U.S. and Russian espionage — is now greater than the number reported by officials in any city except for Havana itself, where the first cases were reported...

The exact cause of the ailments in Vienna, which U.S. government agencies formally refer to as "anomalous health incidents" or "unexplained health incidents," remains unknown, but in response to the surge the C.I.A., the State Department, and other agencies are redoubling their efforts to determine the cause, and to identify the culprit or culprits...

The Havana Syndrome derives its name from the Cuban capital, where C.I.A. officers and State Department employees first reported experiencing strange sensations of sound and pressure in their heads in 2016 and 2017. Some of the patients said the sensations seemed to follow them around their homes, apartments, and hotel rooms in the Cuban capital. Some of the patients described feeling as though they were standing in an invisible beam of energy. Many of them suffered debilitating symptoms, from headaches and vertigo to vision problems. Specialists at the University of Pennsylvania's Center for Brain Injury and Repair used advanced MRIs to study the brains of forty of the original patients from Havana. They found no signs of physical impact to the patients' skulls — it was as if they had "a concussion without a concussion," one specialist told me — and the team detected signs of damage to their brains.

Senior officials in the Trump and Biden Administrations suspect that the Russians are responsible for the syndrome. Their working hypothesis is that operatives working for the G.R.U., the Russian military-intelligence service, have been aiming microwave-radiation devices at U.S. officials, possibly to steal data from their computers or smartphones, which inflicted serious harm on the people they targeted. But American intelligence analysts and operatives have so far been unable to find concrete evidence that would allow them to declare that either microwave radiation or the Russians were to blame.
The article also points out that the CIA's director has privately called the incidents "attacks" rather than incidents or illnesses.

Slashdot reader fahrbot-bot shared some fascinating photos and a report from Live Science.

"This rarely seen glass octopus bared all recently — even a view of its innards — when an underwater robot filmed it gracefully soaring through the deep waters of the Central Pacific Ocean." Like other "glass" creatures, such as glass frogs and certain comb jellies, glass octopuses are almost completely transparent, with only their cylindrical eyes, optic nerve and digestive tract appearing opaque. The expedition crew reported two encounters with the glass octopus — an impressive count given that previously there was such limited footage of these clear cephalopods, scientists had to learn about them by studying chunks of them in the gut contents of their predators...

During the expedition, which ended July 8, a crew of marine scientists discovered a handful of what are likely newfound marine animals on nine previously unexplored submarine mountains known as seamounts. The team also completed high-resolution seafloor mapping of more than 11,500 square miles (30,000 square km) around the archipelago and video recordings of five additional seamounts filmed by the underwater robot SuBastian, according to a statement. SuBastian also snagged footage of a whale shark (the largest living fish in the world) and a long-legged crab stealing a fish from another crab.

The expedition sent SuBastian on 21 dives, enabling the robot to record more than 182 hours on the seafloor.
The expedition was run by the Schmidt Ocean Institute, a nonprofit operating foundation co-founded by Wendy and Eric Schmidt, the former CEO of Google.

sciencehabit shares a report from Science Magazine: Over the past 2 decades, researchers have found hundreds of radioactive atoms, trapped in seafloor minerals, that came from an ancient supernova explosion marking the death of a nearby star. Erupting from hundreds of light-years away, the flash of x-rays and gamma rays probably did no harm on Earth. But the expanding fireball also accelerated cosmic rays -- mostly nuclei of hydrogen and helium -- to close to the speed of light. These projectiles arrived stealthily, decades later, ramping up into an invisible fusillade that could have lasted for thousands of years and might have affected the atmosphere -- and life. In a flurry of studies and speculation, astronomers have sketched out their potential effects, including a depleted ozone layer, cancer-causing particles, wildfires, and a cooling of the climate that could have helped initiate the ice ages 2.5 million years ago. Most paleontologists are yet to be convinced, but astronomers argue that such supernovae could explain some extinction events that lack customary triggers like volcanic outbursts or asteroid impacts.
