Long-time Slashdot reader AmiMoJo quotes the Verge's warning about "deepfake geography: AI-generated images of cityscapes and countryside." Specifically, geographers are concerned about the spread of fake, AI-generated satellite imagery. Such pictures could mislead in a variety of ways. They could be used to create hoaxes about wildfires or floods, or to discredit stories based on real satellite imagery... Deepfake geography might even be a national security issue, as geopolitical adversaries use fake satellite imagery to mislead foes... The first step to tackling these issues is to make people aware there's a problem in the first place, says Bo Zhao, an assistant professor of geography at the University of Washington. Zhao and his colleagues recently published a paper on the subject of "deep fake geography," which includes their own experiments generating and detecting this imagery... As part of their study, Zhao and his colleagues created software to generate deepfake satellite images, using the same basic AI method (a technique known as generative adversarial networks, or GANs) used in well-known programs like ThisPersonDoesNotExist.com. They then created detection software that was able to spot the fakes based on characteristics like texture, contrast, and color. But as experts have warned for years regarding deepfakes of people, any detection tool needs constant updates to keep up with improvements in deepfake generation.

America's Justice Department proposed a new rule Friday to update the definition of "firearm" for the first time since 1968, in an effort to close the so-called "ghost gun" loophole. UPI reports: Attorney General Merrick Garland said the modernized definition would require retailers to perform background checks on customers before selling some ready-made kits that allow people to build their own guns. Such guns are known as "ghost guns" because they don't have serial numbers and can't be traced. "Criminals and others barred from owning a gun should not be able to exploit a loophole to evade background checks and to escape detection by law enforcement," Garland said... Under the proposed rule, manufacturers must include a serial number on the firearm frame or receiver in a kit. Firearm dealers also must add serial numbers to 3D-printed guns or other un-serialized firearms they take into their inventory.

The New York Times reports on surprising silver linings of the global chip shortage: Even as a chip shortage is causing trouble for all sorts of industries, the semiconductor field is entering a surprising new era of creativity, from industry giants to innovative start-ups seeing a spike in funding from venture capitalists that traditionally avoided chip makers. Taiwan Semiconductor Manufacturing Company and Samsung Electronics, for example, have managed the increasingly difficult feat of packing more transistors on each slice of silicon. IBM on Thursday announced another leap in miniaturization, a sign of continued U.S. prowess in the technology race. Perhaps most striking, what was a trickle of new chip companies is now approaching a flood. Equity investors for years viewed semiconductor companies as too costly to set up, but in 2020 plowed more than $12 billion into 407 chip-related companies, according to CB Insights. Though a tiny fraction of all venture capital investments, that was more than double what the industry received in 2019 and eight times the total for 2016. Synopsys, the biggest supplier of software that engineers use to design chip, is tracking more than 200 start-ups designing chips for artificial intelligence, the ultrahot technology powering everything from smart speakers to self-driving cars. Cerebras, a start-up that sells massive artificial-intelligence processors that span an entire silicon wafer, for example, has attracted more than $475 million. Groq, a start-up whose chief executive previously helped design an artificial-intelligence chip for Google, has raised $367 million. "It's a bloody miracle," said Jim Keller, a veteran chip designer whose resume includes stints at Apple, Tesla and Intel and who now works at the A.I. chip start-up Tenstorrent. "Ten years ago you couldn't do a hardware start-up...." More companies are concluding that software running on standard Intel-style microprocessors is not the best solution for all problems. For that reason, companies like Cisco Systems and Hewlett Packard Enterprise have long designed specialty chips for products such as networking gear. Giants like Apple, Amazon and Google more recently have gotten into the act. Google's YouTube unit recently disclosed its first internally developed chip to speed video encoding. And Volkswagen even said last week that it would develop its own processor to manage autonomous driving.

"Colonial Pipeline, which accounts for 45% of the East Coast's fuel, said it has shut down its operations due to a cyberattack," reports ZDNet. "The attack highlights how ransomware and other cyberattacks are increasingly a threat to real-world infrastructure. "The company delivers refined petroleum products such as gasoline, diesel, jet fuel, home heating oil, and fuel for the U.S. Military." The Associated Press reports: Colonial Pipeline said the attack took place Friday and also affected some of its information technology systems. The Alpharetta, Georgia-based company said it hired an outside cybersecurity firm to investigate the nature and scope of the attack and has also contacted law enforcement and federal agencies. "Colonial Pipeline is taking steps to understand and resolve this issue," the company said in a late Friday statement. "At this time, our primary focus is the safe and efficient restoration of our service and our efforts to return to normal operation. This process is already underway, and we are working diligently to address this matter and to minimize disruption to our customers and those who rely on Colonial Pipeline." Oil analyst Andy Lipow said the impact of the attack on fuel supplies and prices depends on how long the pipeline is down. An outage of one or two days would be minimal, he said, but an outage of five or six days could causes shortages and price hikes, particularly in an area stretching from central Alabama to the Washington, D.C., area. Lipow said a key concern about a lengthy delay would be the supply of jet fuel needed to keep major airports operating, like those in Atlanta and Charlotte, North Carolina. The precise nature of the attack was unclear, including who launched it and what the motives were. A Colonial Pipeline spokeswoman declined to say whether the company had received a ransom demand, as is common in attacks from cyber criminal syndicates... Mike Chapple, teaching professor of IT, analytics and operations at the University of Notre Dame's Mendoza College of Business and a former computer scientist with the National Security Agency, said systems that control pipelines should not be connected to the internet and vulnerable to cyber intrusions. "The attacks were extremely sophisticated and they were able to defeat some pretty sophisticated security controls, or the right degree of security controls weren't in place," Chapple said... The article also points out the U.S. government says it's "undertaking a new effort to help electric utilities, water districts and other critical industries protect against potentially damaging cyberattacks....to ensure that control systems serving 50,000 or more Americans have the core technology to detect and block malicious cyber activity. The White House has announced a 100-day initiative aimed at protecting the country's electricity system from cyberattacks by encouraging owners and operators of power plants and electric utilities to improve their capabilities for identifying cyber threats to their networks. It includes concrete milestones for them to put technologies into use so they can spot and respond to intrusions in real time. The Justice Department has also announced a new task force dedicated to countering ransomware attacks...

CNN recently reported on "a batch" of new studies published Wednesday — with one quantifying how much immunity improves after the second dose, and others showing how well coronavirus vaccines work against new variants of the virus: The first nationwide study of coronavirus vaccination, done in Israel, showed Pfizer/BioNtech's vaccine works far better after two doses. Two shots of the vaccine provided greater than 95% protection from infection, severe illness and death, Dr. Eric Haas of the Israel Ministry of Health and colleagues reported in the Lancet medical journal. "Two doses of BNT162b2 are highly effective across all age groups in preventing symptomatic and asymptomatic SARS-CoV-2 infections and COVID-19-related hospitalizations, severe disease, and death, including those caused by the B.1.1.7 SARS-CoV-2 variant," they wrote. The B.1.1.7 variant, first seen in Britain, has spread widely and is now the most common new variant seen in the US. It was also common in Israel when the study was done... "By 14 days after vaccination, protections conferred by a second dose [of the Pfizer vaccine] increased to 96.5% protection against infection, 98% against hospitalization, and 98.1% against death," the team wrote. But people who got only one dose of the vaccine were far less protected. One dose alone gave just 57.7% protection against infection, 75.7% against hospitalization, and 77% against death.... Separately, a team in the Gulf state of Qatar looked at the efficacy of Pfizer's vaccine in the population there when B.1.351 and B.1.1.7 were both circulating. They found reassuring results. "The estimated effectiveness of the vaccine against any documented infection with the B.1.1.7 variant was 89.5% at 14 or more days after the second dose. The effectiveness against any documented infection with the B.1.351 variant was 75%," the researchers wrote in a letter to the New England Journal of Medicine... Vaccine maker Moderna reported Wednesday that a booster shot delivering a half-dose of its current vaccine revs up the immune response against both B.1.351 and P.1. And a booster dose formulated specifically to match B.1.351 was even more effective, Moderna said in a statement... In another study, vaccine maker Novavax confirmed earlier findings that showed its vaccine protects against B.1.351.

"Getting to another extrasolar planet is never going to happen in my lifetime, or that of Western civilisation," says Alan Jackson, an astronomer and planetary scientist at Arizona State University. "But we can have nature deliver pieces of them to us that we can actually see up close." Slashdot reader boudie2 shares this article from BBC Future, which notes that astronomers spent decades looking for objects from outside our solar system — until two arrived at once. "'Oumuamua has not yet been definitively classified as a comet or an asteroid — it might be something else entirely," the article points out. For one thing, 'Oumuamua didn't have a comet-like tail: Two things in particular fixated scientists. The first was its mysterious acceleration away from the Sun, which was hard to reconcile with many ideas about what it might have been made of. The second was its peculiar shape — by some estimates, it was 10 times as long as it was wide. Before 'Oumuamua, the most elongated known space objects were three times longer than they were wide... [F]inally, earlier this year Jackson and his colleague Steven Desch came up with an explanation that seems to explain 'Oumuamua's quirky features, without the need for any alien technology... "We just realised that nitrogen ice could supply exactly the amount of push it needs — and it's observed on Pluto," he says. To corroborate the idea, they calculated how shiny the surface of 'Oumuamua was and compared it to the reflectivity of nitrogen ice — and found that the two were more or less exact matches. The team concluded that the object was likely to be a chunk of nitrogen ice, which was chipped off the surface of a Pluto-like exoplanet around a young star. Based on the evolution of our own solar system, which started out with thousands of similar planets in the icy neighbourhood of the Kuiper belt, they suggested that the fragment may have broken off around half a billion years ago... Though the object would have finally reached the very outermost edge of the Solar System many years ago, it would have taken a long time to travel to the balmy, central region where it was first discovered — and been gradually worn down into a pancake as it approached. This explains its unusual shape and its acceleration in one go, because the evaporating nitrogen would have left an invisible tail that propelled it forwards. "Our atmosphere is mostly nitrogen and you can see though it," says Jackson. "Nitrogen gas is difficult to detect." Again, not everyone is happy with this suggestion. Luckily, the second interstellar object, 2I/Borisov "has turned out to be emphatically less difficult to decipher than its cosmic companion. It's been recognised as the first interstellar comet ever found."

"A ghostly hum has been echoing across the plains of Mars' Jezero Crater," reports Business Insider. Slashdot reader quonset writes: NASA has released a short video of Ingenuity's fourth flight on Mars. However, a bountiful side effect is they were able to hear the hum of its rotors. Perseverance's microphone was turned on during the flight, and despite Ingenuity being over 260 feet away, it was able to capture both sight and sound of the historic event. While the majority of sound is Martian wind rustling against the microphone, NASA enhanced the sound to make the rotor sounds more audible. They are most apparent when Ingenuity returns to its takeoff spot and the rotor hum dies down when the blades come to a halt. "We had carried out tests and simulations that told us the microphone would barely pick up the sounds of the helicopter, as the Mars atmosphere damps the sound propagation strongly," said NASA's science lead for the Perseverance rover's microphone. "We have been lucky to register the helicopter at such a distance. This recording will be a gold mine for our understanding of the Martian atmosphere."

I'm working on the docs for Drummer's twitter verbs today, and came across a few examples from the early days of Twitter lists.

As a basketball fan this is how I look at where we are with Covid in the US. We have a 2 point lead going into the fourth quarter. Our two star players are out with injuries. Our fans are going home, they think the game is won. I know anything could happen at this point.

The reason Warren's campaign failed is that once she was the frontrunner and people got a good look at her, they didn’t like her. She’s kind of what you’d expect, a Harvard professor. They do well at the top of academia, but don’t have a popular touch, and I’m being generous. Certainly there was some sexism, people who wouldn't vote for a woman under any circumstances, but she became the frontrunner with everyone aware of her gender. A woman candidate could have won the nomination in my opinion, someone like Amy Klobuchar or Michigan governor Gretchen Whitmer. It's ridiculous to conclude that a woman couldn't get the nomination, esp since the Democratic nominee in 2016 was a woman. If Warren wants to be president she's going to have to listen to people outside her bubble. People who will, as they say, speak truth to power.

When you hear about new strains of Covid that are ripping into India, as an American do you feel as if it's far away and won't affect me? Does it make you want to get vaccinated? What if our vaccines don't protect against the new strains? Are you ready for a new lockdown?

"It never occurred to me that a Facebook-appointed panel could avoid a clear decision about Donald Trump's heinous online behavior," writes a New York Times technology reporter. "But that is what it's done..." They call the board's decision "kind of perfect, actually, since it forces everyone's hand — from the Facebook chief executive Mark Zuckerberg to our limp legislators in Congress..." The editor of the conservative National Review adds: If Facebook had set out to demonstrate that it has awesome power over speech in the United States, including speech at the core of the nation's political debate, and is wielding that power arbitrarily, indeed has no idea what its own rules truly are or should be, it wouldn't have handled the question any differently... The oversight board underlines the astonishing fact that in reaching its most momentous free-speech decision ever in this country, in determining whether a former president of the United States can use its platform or not, Facebook made it up on the fly. "In applying this penalty," the board writes of the suspension, "Facebook did not follow a clear, published procedure." This is like the U.S. Supreme Court handing down decisions in the absence of a written Constitution, or a home-plate umpire calling balls and strikes without an agreed-upon strike zone... John Samples, a member of the Oversight Board, has even said explicitly that their decision was not about former president Trump — but about Facebook itself. The Washington Post reports: Samples said the board found that Facebook enforced a rule that didn't exist at the time. Trump was suspended indefinitely, rather than permanently or for a specific period of time, as defined by the company's own rules. "In a sense we were being tough with them," Samples said. Other members said the board's call should reassure anyone concerned that Facebook wields too much control over online speech. "Anyone who's concerned about Mark Zuckerberg's power and his company's power over our speech online should actually praise this decision," Julie Owono, executive director of Internet Sans Frontières, said at a virtual event hosted by the Stanford Cyber Policy Center. "The board refused to support an arbitrary suspension..." The flurry of media appearances marked a critical moment in the board's existence, as it tries to prove its legitimacy, define its powers and establish its relationship with Facebook. NPR notes that Former Danish Prime Minister Helle Thorning-Schmidt, a board co-chair, even called Facebook "a bit lazy" for failing to set a specific penalty in the first place... "What we are telling Facebook is that they can't invent penalties as they go along. They have to stick to their own rules," Thorning-Schmidt said in an interview with Axios. The board's criticism didn't stop at Facebook's imposing what it called a "vague, standardless penalty." It slammed the company for trying to outsource its final verdict on Trump. "Facebook has a responsibility to its users and to its community and to the broader public to make its own decisions," Jamal Greene, another board co-chair and constitutional law professor at Columbia, said Thursday during an Aspen Institute event. "The board's job is to make sure that Facebook is doing its job," he said. Tensions between the board's view of the scope of its role and Facebook's were also evident in the board's revelation that the company wouldn't answer seven of the 46 questions it asked about the Trump case. The questions Facebook refused to answer included how its own design and algorithms might have amplified the reach of Trump's posts and contributed to the Capitol assault. "The ones that the company refused to answer to are precisely related to what happened before Jan. 6," Julie Owono, an oversight board member and executive director of the digital rights group Internet Sans Frontières, said at the Aspen Institute event. "Our decision says that you cannot make such an important decision, such a serious decision for freedom of expression, freedom of speech, without the adequate context."

schwit1 shares a report from UPI: The State Department announced it has reached a $13 million settlement with U.S. defense contractor Honeywell International over allegations it exported technical data concerning fighter jets and other military vehicles to foreign countries, including China. The settlement resolves 34 charges the State Department leveled against the company for disclosing dozens of engineering prints showing dimensions, geometries and layouts for manufacturing parts for aircraft, gas turbine engines and military electronics. Honeywell voluntarily informed the department in two disclosures that it had violated arms export control laws by sending the technical drawings to foreign countries, the State Department said in a statement. Honeywell had identified 71-controlled drawings that it had exported to Canada, Ireland, China and Taiwan between July 2011 and October 2015. "The U.S. government reviewed copies of the 71 drawings and determined that exports to and retransfers in the PRC of drawings for certain parts and components for the engine platforms for the F-35 Joint Strike Fighter, B-1B Lancer Long-Range Strategic Bomber and the F-22 Fighter Aircraft harmed U.S. national security," the document said. In a statement emailed to UPI, Honeywell explained it "inadvertently shared" the technology that was assessed as impacting national security during "normal business discussions" but remarked that the schematics were commercially available worldwide. "No detailed manufacturing or engineering expertise was shared," it said. The company has agreed to pay the fine and have an external compliance officer oversee the consent agreement for at least 18 months as well as conduct an external audit of its compliance program.

Bayer AG lost its fight to topple a European Union ban on controversial insecticides that regulators blame for killing honeybees. Bloomberg reports: The EU Court of Justice dismissed the appeal, finding there were no legal errors in the European Commission's decision to impose restrictions on the substances' use, based on concerns that the chemicals posed "high acute risks for bees" and "the survival and development of colonies in several crops." Bayer and Syngenta AG in 2018 already lost a first round in court after telling judges that the EU ban on three so-called neonicotinoids forced farmers to revert to potentially more harmful chemicals. Bayer appealed one more time. The EU's decision five years earlier imposed limits on the use of three neonics -- clothianidin, imidacloprid and thiametoxam -- saying they were "harmful" to Europe's honeybee population when used to treat flowering plants with nectar that attracts the insects. The court ruled on Thursday the commission "is entitled to consider that a risk to the colonies could not be ruled out" even if there is "scientific uncertainty at this stage as to the rate of mortality of individual bees." EU governments in 2018 voted in favor of widening the ban of neonicotinoids to apply everywhere, except for greenhouses. The commission has described the chemicals as "systemic," causing the entire plant to become toxic to bees.
