An anonymous reader shares a report: NASA's Spinoff magazine is one of the things I look forward to reading every year. The space agency's research trickles down to the rest of the world in surprising and interesting ways, which it tracks and collects in this annual publication. This year is no different, and NASA tech can be found in everything from hiking gadgets to heavy industry and, funnily enough, space. There are dozens of technologies that have made their way to everyday use in a variety of places highlighted in this year's issue, which you can browse here [PDF]. I talked with Daniel Lockney, the head of NASA's Tech Transfer Program overseeing the deployment of its tech and research among terrestrial companies looking to put it to good use. "Typically what happens is: NASA develops something, they report it to my office, and we look at it to figure out, first, does it work? And second, who else can use it? And if someone can, we figure out how to get it to them," Lockney explained. "I try to give as much away for free as I can. I've got no direction to generate revenue or bring something back to the U.S. treasury. The 1958 NASA act that created us says to disseminate our work -- nothing in there about making a dime."

The result is cheap or free licensing of interesting tech like compact, long-lasting water filters, unusual mechanical components, and other tech that was needed for space or launch purposes but might find a second use on the ground. Lockney highlighted a couple items in the latest batch that he thought were especially interesting. "There was a partnership with GM to develop the Robo-Glove, a functional glove that astronauts will wear to help reduce strain during repetitive tasks and increase grip strength," he said. "Squeezing something on a spacewalk, you can do it a couple times, but if you're gripping a tool for the whole afternoon... so we developed this glove to assist in that work, and now it's being used at factories around the world."

Mark Cuban's announcement over the weekend of an online pharmacy selling over a hundred generic drugs at near cost was totally unexpected but will likely be welcomed by millions who struggle to afford medication. The billionaire told TechCrunch that the business model is refreshingly simple: "Lower pricing reduces patient stress, and that will lead to more customers." From the report: The Cost Plus Drug Company aims very simply to provide as many common medications as possible in generic form at as low a price as possible. All cash, no IP deals, no insurance companies -- just buy pills for what they cost to make, plus 15 percent to cover overhead. Asked about ROI, Cuban admitted there isn't much to speak of, by design. "I want to be above break even while maximizing the number of people who can afford their medications," he said. "Shoot. I would be happy if we can make a little, but push pricing of generics sold elsewhere down significantly. Our challenge is to keep pushing prices lower," not compete with anyone, he continued. "Our KPI is how much we can reduce the stress of our patients who buy generic meds. When people save a lot of money on their medications, they often will tell others they know that have the same challenges. That word of mouth impacts our growth the most."

Friday the results of several large studies showed that getting a third Covid vaccine "booster shot" dramatically decreased infections from the Omicron variant.

And now the Times of Israel reports that the country's Health Ministry "said on Sunday that the fourth vaccine dose for those aged 60 and up offers a threefold protection against serious illness and twofold protection against infection in the current wave driven by the Omicron variant." The ministry said the figures are the result of initial analysis by experts from various leading academic and health institutions, and compares the fourth vaccine with those who received three doses at least four months ago.

The figures are based on 400,000 Israelis who received the fourth vaccine and 600,000 who received three doses, with the ministry stressing that the methodology is similar to previous papers the experts have published in the peer-reviewed New England Journal of Medicine.

CNET reports: Saturn has some famous moons, like Enceladus (a plume-spewing moon of mystery) and Titan (the intriguing target of NASA's future Dragonfly mission). But what about dainty Mimas, a moon that's mostly known for its resemblance to the Star Wars Death Star?

Turns out it might be hiding an ocean.

A study published in the journal Icarus lays out evidence that suggests Mimas has liquid deep under its icy surface. "If Mimas has an ocean, it represents a new class of small, 'stealth' ocean worlds with surfaces that do not betray the ocean's existence," said lead author Alyssa Rhoden in a Southwest Research Institute (SwRI) statement on Wednesday. Mimas might look quiet, but NASA's now-defunct Saturn-studying Cassini spacecraft "identified a curious libration, or oscillation, in the moon's rotation, which often points to a geologically active body able to support an internal ocean," SwRI said.

The libration spotted by Cassini suggests Mimas's interior is warm enough for a liquid ocean, but not so warm it compromises the moon's thick shell of ice.

The researchers calculate that ice shell could be up to 19 miles (31 kilometers) thick. There's a nifty acronym for interior water ocean worlds: IWOWs. Known IWOWs include Enceladus, Titan and Jupiter's fascinating moon Europa. These places are particularly interesting because they may be habitable for microbial life.

"If a rock falls on Mars, and no one is there to see it, does it leave a trace?" jokes the New York Times, answering "Yes, and it's a beautiful herringbone-like pattern, new research reveals." Scientists have now spotted thousands of tracks on the red planet created by tumbling boulders. Delicate chevron-shaped piles of Martian dust and sand frame the tracks, the team showed, and most fade over the course of a few years.

Rockfalls have been spotted elsewhere in the solar system, including on the moon and even a comet. But a big open question is the timing of these processes on other worlds — are they ongoing or did they predominantly occur in the past?A study of these ephemeral features on Mars, published last month in Geophysical Research Letters, says that such boulder tracks can be used to pinpoint recent seismic activity on the red planet. This new evidence that Mars is a dynamic world runs contrary to the notion that all of the planet's exciting geology happened much earlier, s aid Ingrid Daubar, a planetary scientist at Brown University who was not involved in the study...

To arrive at this finding, Vijayan, a planetary scientist at the Physical Research Laboratory in Ahmadabad, India, who uses a single name, and his colleagues pored over thousands of images of Mars' equatorial region. The imagery was captured from 2006 through 2020 by the High Resolution Imaging Science Experiment (HiRISE) camera onboard NASA's Mars Reconnaissance Orbiter and revealed details as small as 10 inches across. "We can discriminate individual boulders," Vijayan said. The team manually searched for chain-like features — a telltale signature of a rock careening down an incline — on the sloped walls of impact craters. Vijayan and his collaborators spotted more than 4,500 such boulder tracks, the longest of which stretched more than a mile and a half...

Roughly one-third of the tracks the researchers studied were absent in early images, meaning that they must have formed since 2006... The researchers suggest that winds continuously sweeping over the surface of Mars redistribute dust and sand and erase the ejecta. Because boulder fall ejecta fades so rapidly, seeing it implies that a boulder was dislodged recently, the team suggest. And a common cause of rockfalls, on Earth and elsewhere, is seismic activity.... Since 2019, hundreds of marsquakes have been detected by NASA's InSight lander, and two of the largest occurred last year in the Cerberus Fossae region.
Today the Mars lander InSight is back in operation after a two-week break to avoid dust storms, while dust storms also delayed the 19th flight of NASA's Ingenuity helicopter.

And elsewhere on Mars, the Perserverance rover successfully dislodged two pebbles stuck in its sample-collecting apparatus.

In 1992 John Conway raised a question about the patterns in his famous mathematical Game of Life: "Is there a Godlike still-life, one that can only have existed for all time (apart from things that don't interfere with it)?"

Conway closed his note by adding "Well, I'm going out to get a hot dog now..." And then, nearly 30 years later, a mathematical blog reports: Ilkka Törmä and Ville Salo, a pair of researchers at the University of Turku in Finland, have found a finite configuration in Conway's Game of Life such that, if it occurs within a universe at time T, it must have existed in that same position at time T-1 (and therefore, by induction, at time 0)...

The configuration was discovered by experimenting with finite patches of repeating 'agar' and using a SAT solver to check whether any of them possess this property.
The blogger also shares some other Game of Life-related news:

• David Raucci discovered the first oscillator of period 38. The remaining unsolved periods are 19, 34, and 41.
• Darren Li has connected Charity Engine to Catagolue, providing approximately 2000 CPU cores of continuous effort and searching slightly more than 10^12 random initial configurations per day.
• Nathaniel Johnston and Dave Greene have published a book on Conway's Game of Life, featuring both the theoretical aspects and engineering that's been accomplished in the half-century since its conception. Unfortunately it was released slightly too early to include the Törmä-Salo result or Raucci's period-38 oscillator.

"Scientists have estimated the number of 'small' black holes in the universe," reports Live Science. "And no surprise: It's a lot." Using a new method, outlined January 12 in The Astrophysical Journal, a team of astrophysicists has produced a fresh estimate for the number of stellar-mass black holes — those with masses 5 to 10 times that of the sun — in the universe.

And it's astonishing: 40,000,000,000,000,000,000, or 40 quintillion, stellar-mass black holes populate the observable universe, making up approximately 1% of all normal matter, according to the new estimate.

So how did the scientists arrive at that number? By tracking the evolution of stars in our universe they estimated how often the stars — either on their own, or paired into binary systems — would transform into black holes, said first author Alex Sicilia, an astrophysicist at the International School of Advanced Studies (SISSA) in Trieste, Italy. "This is one of the first, and one of the most robust, ab initio [ground up] computation[s] of the stellar black hole mass function across cosmic history," Sicilia said in a statement....

To arrive at their estimate, the astrophysicists modeled not just the lives, but the pre-lives of the universe's stars. Using known statistics of various galaxies, such as their sizes, the elements they contain, and the sizes of the gas clouds stars would form in, the team built a model of the universe that accurately reflected the different sizes of stars that would be made, and how often they would be created.... [T]he researchers designed a model that tracked the population and size distribution of stellar-mass black holes over time to give them their eye-watering number. Then, by comparing the estimate with data taken from gravitational waves, or ripples in space-time, formed by black hole and binary star mergers, the researchers confirmed that their model was in good agreement with the data.

Astrophysicists hope to use the new estimate to investigate some perplexing questions that arise from observations of the very early universe — for instance, how the early universe became so quickly populated by supermassive black holes — often with masses millions, or even billions, of times greater than the stellar-mass holes the researchers examined in this study — so soon after the Big Bang.

"Three studies released Friday offered more evidence that COVID-19 vaccines are standing up to the omicron variant, at least among people who received booster shots," reports the Associated Press: They are the first large U.S. studies to look at vaccine protection against omicron, health officials said. The papers echo previous research — including studies in Germany, South Africa and the U.K. — indicating available vaccines are less effective against omicron than earlier versions of the coronavirus, but also that boosters doses rev up virus-fighting antibodies to increase the chance of avoiding symptomatic infection.

The first study looked at hospitalizations and emergency room and urgent care center visits in 10 states, from August to this month. It found vaccine effectiveness was best after three doses of the Pfizer or Moderna vaccines in preventing COVID-19-associated emergency department and urgent care visits. Protection dropped from 94% during the delta wave to 82% during the omicron wave. Protection from just two doses was lower, especially if six months had passed since the second dose. Officials have stressed the goal of preventing not just infection but severe disease. On that count, some good news: A third dose was at least 90% effective at preventing hospitalizations for COVID-19, both during the delta and omicron periods, the study also found.

The second study focused on COVID-19 case and death rates in 25 states from the beginning of April through Christmas. People who were boosted had the highest protection against coronavirus infection, both during the time delta was dominant and also when omicron was taking over...

The Journal of the American Medical Association published the third study, also led by CDC researchers. It looked at people who tested positive for COVID-19 from Dec. 10 to Jan. 1 at more than 4,600 testing sites across the U.S. Three shots of the Pfizer and Moderna vaccines were about 67% effective against omicron-related symptomatic disease compared with unvaccinated people. Two doses, however, offered no significant protection against omicron when measured several months after completion of the original series, the researchers found.

MIT, Brigham, and Women's Hospital researchers are working to eliminate many of the headaches associated with treating diabetes. According to Engadget, "They're developing all-in-one devices that measure glucose, calculate the necessary insulin dose and inject you accordingly." From the report: The first device includes the blood-drawing lancet, glucose test strips and an insulin needle. Users would first take a photo of their meal using a smartphone app to estimate the food volume and carbohydrate levels. After that, they'd start the automated process of collecting blood, calculating glucose (again through the app) and delivering the appropriate amount of insulin. The second gadget would only need one needle jab -- it would build the glucose sensor into the insulin needle and inject the appropriate amount of insulin. You'd have to wait five to ten seconds, but you wouldn't have to stick yourself twice.

The technology is still some ways off. While the first device would use parts that were already FDA-approved, it hasn't been tested in humans. The second, meanwhile, uses a new sensor type that will likely require more work to be testable with humans. Scientists have filed patents for both devices and are hoping to work with companies on further development. There's a strong motivation to bring these devices to market, at least. People with diabetes would only need to use one device at meals, and with the hybrid sensor/needle might suffer less pain. That, in turn, could encourage consistent treatment that improves your overall wellbeing.

In 2021, there was an upsurge in peculiar sightings reported, thanks to people with smartphones or other video gear that captured these strange glimmers in the sky. In 2022, UAP will get more attention from both the scientific community and the federal government, experts told Space.com. From the report: One potential major development in 2022 will be UFO detection, according to Mark Rodeghier, scientific director of the Center for UFO Studies in Chicago. "The effort to detect, track and measure the UFO phenomenon in the field, in real time, has recently entered a new phase," Rodeghier told Space.com. "The technology has gotten better, software tools have improved and the current interest in UFOs has attracted new, qualified professionals. "While one can't predict how soon we will gain new, fundamental knowledge about UAP/UFOs, I believe that these efforts are very likely to succeed and set UFO research onto a new foundation of reliable, physical data," Rodeghier added. "And as a consequence, we will have even more evidence -- as if it was needed -- that the UFO phenomenon is real and can be studied scientifically."

One upcoming initiative, called the Galileo Project, will search for extraterrestrial equipment near Earth. It has two branches. The first aims to identify the nature of interstellar objects that do not resemble comets or asteroids -- like 'Oumuamua, the first known interstellar object to visit the solar system. The second branch targets UAP, similar to those of interest to the U.S. government. "The Galileo Project's data will be open to the public, and its scientific analysis will be transparent," said Harvard astronomer Avi Loeb, who is spearheading the project. "The related scientific findings would expand humanity's knowledge, with no attention to borders between nations." The Galileo research team includes more than 100 scientists who plan to assemble the project's first telescope system on the roof of the Harvard College Observatory in spring 2022. "The system will record continuous video and audio of the entire sky in the visible, infrared and radio bands, as well as track objects of interest," Loeb said. "Artificial intelligence algorithms will distinguish birds from drones, airplanes or something else. Once the first system will operate successfully, the Galileo Project will make copies of it and distribute them in many geographical locations."

Currently, there is a lack of coordination among organizations involved in UAP detection equipment, but that may change this year, said Robert Powell, an executive board member of the Scientific Coalition for UAP Studies (SCU) in Austin, Texas. "I believe that will improve as we go into 2022," he said. A number of SCU members are involved with the Galileo Project, and the organization has partnered with several groups, including UFODATA, the UFO Data Acquisition Project (UFODAP) and UAPx. "UFODAP already has a working model that has been sold into the marketplace and is reasonably priced in the $2,000 to $5,000 range, depending on the accessories desired," Powell told Space.com. "This system has already been used by a group known as UAPx to collect data. Our goal is to coordinate these activities in a way such that we use a system with standardized equipment set to collect data." But before that happens, Powell said, the groups need to plot out exactly what that equipment is trying to measure and verify that the system can achieve that goal.

A first-of-its-kind "green" Shell facility in Alberta is emitting more greenhouse gases than it's capturing, throwing into question whether taxpayers should be funding it, a new report has found. Motherboard reports: Shell's Quest carbon capture and storage facility in the Alberta tarsands captured 5 million tonnes of carbon dioxide at its hydrogen-producing plant in its Scotford complex between 2015 and 2019. But a new report from human rights organization Global Witness found the hydrogen plant emitted 7.5 million tons of greenhouse gases in the same timeframe -- including methane, which has 80 times the warming power of carbon during its first 20 years in the atmosphere, and accounts for about a quarter of man-made warming today. To put that in perspective, the "climate-forward" part of the Scotford plant alone has the same carbon footprint per year as 1.2 million fuel-powered cars, Global Witness said.

"We do think Shell is misleading the public in that sense and only giving us one side of the story," said Dominic Eagleton, who wrote the report. He said industry's been pushing for governments to subsidize the production of fossil hydrogen (hydrogen produced from natural gas) that's supplemented with carbon capture technology as a "climate-friendly" way forward, but the new report shows that's not the case. In an email, Shell said the facility was introduced to display the merits of carbon capture technology, but didn't directly respond to the allegation that its hydrogen component emitted 7.5 million tons of greenhouse gases.

After 17 years of relatively smooth sailing, NASA's Neil Gehrels Swift Observatory has entered safe mode after detecting a "possible failure" in one of the six reaction wheels used to change attitude. Engadget reports: While it's not clear exactly what (if anything) went wrong, NASA has halted direction-based scientific observations until it can either give the all-clear or continue operations with five wheels. This is the first potential reaction wheel problem since the Swift Observatory began operations in February 2005, NASA said. The rest of the vehicle is otherwise working properly.

The Swift Observatory has played an important role in astronomy over the past two decades. It was primarily built to detect gamma-ray bursts and detects roughly 70 per day. However, it has increasingly been used as a catch-all observer across multiple wavelengths, spotting solar flares and hard-to-find stars. NASA won't necessarily run into serious trouble if Swift has a lasting problem, but it would clearly benefit from keeping the spacecraft running as smoothly as possible.

nickwinlund77 shares a report from SciTechDaily: UNSW Sydney-led research paves the way for large silicon-based quantum processors for real-world manufacturing and application. Australian researchers have proven that near error-free quantum computing is possible, paving the way to build silicon-based quantum devices compatible with current semiconductor manufacturing technology. [...] [The researcher's] paper is one of three published today in Nature that independently confirm that robust, reliable quantum computing in silicon is now a reality. This breakthrough is featured on the front cover of the journal.

[Professor Andrea Morello of UNSW, who led the work] et al achieved 1-qubit operation fidelities up to 99.95 percent, and 2-qubit fidelity of 99.37 percent with a three-qubit system comprising an electron and two phosphorous atoms, introduced in silicon via ion implantation. A Delft team in the Netherlands led by Lieven Vandersypen achieved 99.87 percent 1-qubit and 99.65 percent 2-qubit fidelities using electron spins in quantum dots formed in a stack of silicon and silicon-germanium alloy (Si/SiGe). A RIKEN team in Japan led by Seigo Tarucha similarly achieved 99.84 percent 1-qubit and 99.51 percent 2-qubit fidelities in a two-electron system using Si/SiGe quantum dots.

The UNSW and Delft teams certified the performance of their quantum processors using a sophisticated method called gate set tomography, developed at Sandia National Laboratories in the U.S. and made openly available to the research community. Morello had previously demonstrated that he could preserve quantum information in silicon for 35 seconds, due to the extreme isolation of nuclear spins from their environment. But the trade-off was that isolating the qubits made it seemingly impossible for them to interact with each other, as necessary to perform actual computations. Today's paper describes how his team overcame this problem by using an electron encompassing two nuclei of phosphorus atoms. The three papers from the UNSW team, Delft team and RIKEN group in Tokyo can be found at their respective links.

An anonymous reader quotes a report from The Guardian: An initial CIA investigation into the mysterious set of symptoms known as Havana syndrome has found that it is unlikely to be the result of a worldwide campaign of attacks by a foreign power against US diplomats and spies. However, two dozen cases, including some of those originally afflicted in Havana in 2016, could not be explained and would be further studied for evidence of a possible attack, according to a senior CIA official who briefed the US press.

"While we have reached some significant interim findings, we are not done," the CIA director, Williams Burns, said in a statement. "We will continue the mission to investigate these incidents and provide access to world-class care for those who need it." Since the original outbreak of the symptoms, which include hearing strange sounds, dizziness, loss of balance, nausea and memory loss, more than 1,000 cases have been studied around the world. The interim findings of a CIA investigation have found that the majority of cases could probably be attributed to a pre-existing medical condition, or environmental factors, or stress, the senior official said. The defense department and an independent panel of experts are conducting their own investigations which have yet to publish reports. A Havana syndrome victims support group said in a statement: "The decision to release the report now and with this particular set of 'findings' seems a breach of faith, and an undermining of the intent of Congress and the president to stand with us and reach a government-wide consensus as to what is behind this," a Havana syndrome victims group said in a statement.

"This report was neither cleared nor coordinated through the interagency and must stand as the assessment of one agency [CIA] alone."

Elon Musk's brain implant company Neuralink is now hiring a clinical trial director, an indication that the company's longstanding goal of implanting chips in human brains is coming closer. Bloomberg: The trial director position would oversee the startup's long-promised human trials of its medical device, according to the listing. Neuralink's brain implant -- which Musk has said already allows monkeys to play video games with their thoughts alone -- is intended to help treat a variety of neurological disorders, such as paralysis. The job description for the position, based in Fremont, California, promises that the applicant will "work closely with some of the most innovative doctors and top engineers" as well as with "Neuralink's first Clinical Trial participants." It also indicates that the job will mean leading and building "the team responsible for enabling Neuralink's clinical research activities," as well as adhering to regulations. Last month, Musk told the Wall Street Journal that Neuralink hoped to implant its device in human brains sometime in 2022.
