Residents of Shenzhen saw truly driverless cars on the road today. From a report: AutoX, a four-year-old startup backed by Alibaba, MediaTek and Shanghai Motors, deployed a fleet of 25 unmanned vehicles in downtown Shenzhen, marking the first time any autonomous driving car in China tests on public roads without safety drivers or remote operators. The cars, meant as robotaxis, are not yet open to the public, an AutoX spokesperson told TechCrunch. The milestone came just five months after AutoX landed a permit from California to start driverless tests, following in the footsteps of Waymo and Nuro. It also indicates that China wants to bring its smart driving industry on par with the U.S. Cities from Shenzhen to Shanghai are competing to attract autonomous driving upstarts by clearing regulatory hurdles, touting subsidies and putting up 5G infrastructure. As a result, each city ends up with its own poster child in the space: AutoX and Deeproute.ai in Shenzhen, Pony.ai and WeRide in Guangzhou, Momenta in Suzhou and Baidu's Apollo fleet in Beijing, to name a few. The autonomous driving companies, in turn, work closely with traditional carmakers to make their vehicles smarter and more suitable for future transportation.

The Trump administration has sued Facebook, accusing the social-media company of illegally reserving high-paying jobs for immigrant workers it was sponsoring for permanent residence, rather than searching adequately for available U.S. workers who could fill the positions. From a report: In a 17-page complaint filed Thursday, the Justice Department's civil-rights division said Facebook inadequately advertised at least 2,600 positions between 2018 and 2019 that were filled by immigrants on H-1B high-skill visas when the company was applying to sponsor those workers for permanent residency, known as green cards. Companies sponsoring workers for employment-based green cards are required to show as part of the federal application process that they couldn't find any qualified American workers to fill the job. The suit said Facebook didn't advertise the reserved positions on its website and required candidates to mail in their applications rather than accepting them online. "And even when U.S. workers do apply, Facebook will not consider them for the advertised positions," the suit alleges. "Simply put, Facebook reserves these positions for temporary visa holders."

When Warner Bros. announced that "Wonder Woman 1984" would land on the streaming service HBO Max on Christmas, the same time it debuts in theaters, many expected it to be an isolated case in response to an unprecedented pandemic. From a report: Instead, the studio will deploy a similar release strategy for the next twelve months. In a surprising break from industry standards, Warner Bros.' entire 2021 slate -- a list of films that includes "The Matrix 4," Denis Villeneuve's "Dune" remake, Lin-Manuel Miranda's musical adaptation of "In the Heights," Sopranos prequel "The Many Saints of Newark," and "The Suicide Squad" -- will debut both on HBO Max and in theaters on their respective release dates. The shocking move to simultaneously release movies day-and-date underscores the crisis facing movie theaters and the rising importance of streaming services in the wake of a global health crisis that's decimated the film exhibition community.

PC maker powerhouse Dell announced today a flurry of new enterprise security solutions for the company's line of enterprise products. From a report: The new services can be grouped into two categories, with (1) new solutions meant to protect the supply chain of Dell products while in transit to their customers and (2) new features meant to improve the security of Dell products while in use. While Dell has previously invested in securing its customers' supply chains, the company has announced today three new services. The first is named SafeSupply Chain Tamper Evident Services and, as its name implies, involves Dell adding anti-tampering seals to its devices, transport boxes, and even entire pallets before they leave Dell factories. The anti-tampering seals will allow buyers of Dell equipment to determine if any intermediary agents or transporters have opened boxes or devices to alter physical components. The second supply chain security offering, named the Dell SafeSupply Chain Data Sanitization Services, is meant for tampering made at the storage level.

AstraZeneca and Oxford University have given conflicting accounts of how they came upon the most effective dosing pattern for their COVID-19 vaccine, a rare instance of public dissension between major institutions collaborating on a pivotal project. From a report: The discrepancy, reported for the first time by Reuters, centres on the regimen administered to a smaller group of volunteers in the late-stage trials, of half a dose followed by a full dose. This diverged from the original plan of two full doses, given to the majority of participants. The half-dose pattern was found to be 90% effective, versus the 62% success rate of the two-full-dose main study, based on interim data. AstraZeneca's research chief told Reuters 10 days ago, when interim trial data was released, the half-dose was given inadvertently as a first shot to some trial participants, and emerged as a stroke of fortune -- "serendipity" -- that scientists expertly harnessed. This narrative was refuted by a leading Oxford University scientist, however, who told Reuters on Monday that the half-dose shot was given deliberately after thorough consultations. Uncertainty over how the dosing regimen came about raises questions about the robustness of the data, according to some experts who said it risked slowing down the process of gaining regulatory approval for the shot and denting public confidence. "These differing accounts are worrying," Eleanor Riley, a professor of immunology and infectious disease at the University of Edinburgh, told Reuters. "Trust is at a premium when it comes to vaccines and we must not do anything that might in any way undermine it."

An anonymous reader shares a report: Dec. 2 was the 25th anniversary of the Solar and Heliospheric Observatory (SOHO), a joint project from NASA and the European Space Agency. To celebrate, the agencies released a dramatic, nearly 50-minute-long video showing the sun blasting out solar material from 1998 through 2020. The SOHO spacecraft constantly stares at the sun, recording its every whim. It's spectacular and mesmerizing. "What becomes clear as the sun turns and years pass and background stars whirl by, is how constant the stream of material is that is blasted in all directions -- the solar wind," ESA said in a statement on Wednesday. "This constant wind is interrupted only by huge explosions that fling bows of material at vast speeds, filling the solar system with ionized material and solar radiation."

The personal information of more than 243 million Brazilians, including alive and deceased, has been exposed online after web developers left the password for a crucial government database inside the source code of an official Brazilian Ministry of Health's website for at least six months. From a report: The security snafu was discovered by reporters from Brazilian newspaper Estadao, the same newspaper that last week discovered that a Sao Paolo hospital leaked personal and health information for more than 16 million Brazilian COVID-19 patients after an employee uploaded a spreadsheet with usernames, passwords, and access keys to sensitive government systems on GitHub. Estadao reporters said they were inspired by a report filed in June by Brazilian NGO Open Knowledge Brasil (OKBR), which, at the time, reported that a similar government website also left exposed login information for another government database in the site's source code. Since a website's source code can be accessed and reviewed by anyone pressing F12 inside their browser, Estadao reporters searched for similar issues in other government sites.

With vaccines against Covid-19 on the verge of being rolled out around the world, Facebook said it will start removing false claims about the immunizations that have been debunked by public health experts. From a report: The move announced Thursday adds to Facebook's policy of taking down misinformation about the deadly virus that could lead to imminent physical harm. The type of posts that could be removed on Facebook or Instagram include false claims about the safety, efficacy, ingredients or side effects of the vaccine, Facebook said. These could include claims that the vaccines contain microchips or anything else not on the official ingredient list. In October, Facebook said it would ban ads that discourage people from getting vaccines in general, not just for Covid.

IBM's cyber-security division says that hackers are targeting companies associated with the storage and transportation of COVID-19 vaccines using temperature-controlled environments -- also known as the COVID-19 vaccine cold chain. From a report: The attacks consisted of spear-phishing emails seeking to collect credentials for a target's internal email and applications. While IBM X-Force analysts weren't able to link the attacks to a particular threat actor, they said the phishing campaign showed the typical "hallmarks of nation-state tradecraft." Targets of the attacks included a wide variety of companies, sectors, and government organizations alike.

An Amazon Web Services (AWS) virtualization engineer has shown what Windows 10 on Arm could be like if Microsoft licensed its Arm-based OS to the public rather than just to Windows 10 manufacturers. From a report: With Apple's new M1 Arm-based system on chip, Mac users who need to use Windows 10 can't run Microsoft's Arm-based version of Windows using Apple's Bootcamp. The key obstacle is that Microsoft doesn't license Windows 10 on Arm to any entities other than its own Surface group and Windows 10 on Arm OEMs like HP, Asus and Lenovo. Technically, there's nothing stopping owners of the M1 MacBook Air, MacBook Pro 13-inch or Mac mini from running Windows 10 on Arm, as Apple's software engineering chief Craig Federighi recently pointed out. [...] But Microsoft's reluctance to create a license for Windows 10 on Arm for end users hasn't stopped creative engineers from putting together a working example of what things could be like if it did. AWS principal engineer Alexander Graf did just that, using the open-source QEMU virtualization software for Windows on Arm. QEMU emulates access to hardware such as the CPU and GPU. [...] "Who said Windows wouldn't run well on #AppleSilicon? It's pretty snappy here," Graf wrote in a tweet. Graf previously worked on the Kernel Virtual Machine (KVM) for Linux distribution SUSE for over a decade. Now he's a KVM developer at AWS, which this week announced new Mac instances for AWS Elastic Compute Cloud (EC2) based on Nitro System, an AWS hypervisor for EC2 instances. [...] A developer using the handle @imbushuo on Twitter has posted Geekbench versions 4 and 5 scores that compare Windows 10 on Arm on an M1 computer with the Microsoft-made Surface Pro X. Windows on an M1 got a single-core score of 1,288 and multi-core score of 5,685 whereas the Surface Pro X's scores were roughly 800 and 3,000 in those respective benchmarks.

An anonymous reader quotes a report from Reuters: A group of U.S. states led by New York is investigating Facebook for possible antitrust violations and plans to file a lawsuit against the social media giant next week, four sources familiar with the matter said on Wednesday. The complaint would be the second major lawsuit filed against a Big Tech company this year. The Justice Department sued Alphabet's Google in October. More than 40 states plan to sign on to the lawsuit, one source said, without naming them. It is not known what the states plan to include in their complaint. One allegation often made against Facebook is that it has strategically sought to buy small potential rivals, often at a big premium. These include Instagram in 2012 and WhatsApp in 2014. Facebook Chief Executive Mark Zuckerberg has argued in congressional testimony that the company has a range of competitors, including other tech giants. He has defended controversial acquisitions like Instagram and WhatsApp by saying the social media platform helped them expand from small, insignificant companies into powerhouses.

Natalie Wolchover writes via Quanta Magazine: As fundamental constants go, the speed of light, c, enjoys all the fame, yet c's numerical value says nothing about nature; it differs depending on whether it's measured in meters per second or miles per hour. The fine-structure constant, by contrast, has no dimensions or units. It's a pure number that shapes the universe to an astonishing degree -- "a magic number that comes to us with no understanding," as Richard Feynman described it. Paul Dirac considered the origin of the number "the most fundamental unsolved problem of physics." Numerically, the fine-structure constant, denoted by the Greek letter a (alpha), comes very close to the ratio 1/137. It commonly appears in formulas governing light and matter. [...] The constant is everywhere because it characterizes the strength of the electromagnetic force affecting charged particles such as electrons and protons. Because 1/137 is small, electromagnetism is weak; as a consequence, charged particles form airy atoms whose electrons orbit at a distance and easily hop away, enabling chemical bonds. On the other hand, the constant is also just big enough: Physicists have argued that if it were something like 1/138, stars would not be able to create carbon, and life as we know it wouldn't exist. Today, in a new paper in the journal Nature, a team of four physicists led by Saida Guellati-Khelifa at the Kastler Brossel Laboratory in Paris reported the most precise measurement yet of the fine-structure constant. The team measured the constant's value to the 11th decimal place, reporting that a = 1/137.03599920611. (The last two digits are uncertain.) With a margin of error of just 81 parts per trillion, the new measurement is nearly three times more precise than the previous best measurement in 2018 by Muller's group at Berkeley, the main competition. (Guellati-Khelifa made the most precise measurement before Muller's in 2011.) Muller said of his rival's new measurement of alpha, "A factor of three is a big deal. Let's not be shy about calling this a big accomplishment."

Singapore has granted San Francisco start-up Eat Just Inc. regulatory approval to sell its laboratory-grown chicken in the city-state -- the world's first government to allow the sale of cultured meat. CNN reports: The product, created from cultured chicken cells, has been approved as an ingredient in chicken bites following Singapore Food Agency (SFA) approval, Eat Just said Tuesday. Initially, the chicken bites will debut in a Singapore restaurant, with plans for wider expansion into dining and retail establishments in the country, Josh Tetrick, co-founder and CEO of Eat Just told CNN Business. The product will be priced at parity with premium chicken, he added. The cultured meat is created in a bioreactor -- an apparatus in which a biological reaction or change takes place -- Eat Just said. It has a high protein content and is a rich source of minerals, according to the company, which plans to sell the product under the GOOD Meat brand. For now, with manufacturing hubs in Singapore and Northern California, the company only has approval to sell the meat in Singapore, but it hopes to expand sales of cultured meat -- including cultured beef -- into the US and Western Europe, Tetrick said.

An anonymous reader quotes a report from Ars Technica: President Donald Trump has long been an outspoken foe of big technology companies. And in recent months, he has focused his ire on Section 230, a provision of the 1996 Communications Decency Act that shields online platforms from liability for content posted by their users. In May, Trump called on the Federal Communications Commission to reinterpret the law -- though it's not clear the agency has the power to do that. Since then, he has tweeted about the issue incessantly. On Tuesday evening, Trump ratcheted up his campaign against Section 230. In a tweet, he called the law "a serious threat to our National Security & Election Integrity." He warned that "if the very dangerous & unfair Section 230 is not completely terminated as part of the National Defense Authorization Act (NDAA), I will be forced to unequivocally VETO the Bill." The NDAA is a massive spending bill that Congress passes each year to authorize funding for the military. This year's version, now under active discussion on Capitol Hill, is expected to cost around $740 billion. The NDAA is seen as a "must pass" bill because no one wants to be blamed for holding up funding for the troops. So inserting language into it can be a way to pass proposals that might not stand on their own. But there's also a risk of a backlash -- especially if a measure is seen as unrelated to the military. This may be why Trump has started claiming that Section 230 is a "threat to our national security," since that would theoretically make it germane to a defense funding bill. Trump's campaign to repeal Section 230 appears to go beyond mere tweets. The White House is reportedly telling members of Congress the same thing in private that the president is telling his 88 million Twitter followers: that he will veto the NDAA if it doesn't repeal or at least overhaul Section 230.

sciencehabit writes: The U.K. government today invited communities around the country to volunteer a site for a prototype fusion reactor, which would be the first -- it is hoped -- to put electricity into the grid. The project, called Spherical Tokamak for Energy Production (STEP), began last year with an initial 222 million pounds over 5 years to develop a design. The U.K. Atomic Energy Authority, the government agency overseeing the effort, says construction could begin as soon as 2032, with operations by 2040. Still, spherical tokamaks also come with drawbacks. The hot dense plasma in a smaller device is more punishing on materials, so components may need to be replaced more often. And STEP is unlikely to be capable of breeding tritium, one of two hydrogen isotopes that fuels the reactor. Tritium is radioactive with a half-life of 12 years and global supplies are low. A working reactor will have to breed its own tritium by surrounding the vessel with patches of lithium that produce tritium when bombarded by neutrons from the fusion reaction.

AmiMoJo shares a report from the BBC: The winning numbers in South Africa's national lottery have caused a stir and sparked accusations of fraud over their unusual sequence. Tuesday's PowerBall lottery saw the numbers five, six, seven, eight and nine drawn, while the Powerball itself was, you've guessed it, 10. Some South Africans have alleged a scam and an investigation is under way. The organizers said 20 people purchased a winning ticket and won 5.7 million rand ($370,000; 278,000 pounds) each. Another 79 ticketholders won 6,283 rand each for guessing the sequence from five up to nine but missing the PowerBall. The chances of winning South Africa's PowerBall lottery are one in 42,375,200 -- the number of different combinations when selecting five balls from a set of 50, plus an additional bonus ball from a pool of 20. The odds of the draw resulting in the numbers seen in Tuesday's televised live event are the same as any other combination. Competitions resulting in multiple winners are rare, but this may have something to do with this particular sequence.

schwit1 shares a report from Autoblog, adding: "And CR decides to predict poor reliability on EVs it hasn't even evaluated yet." From the report: The latest auto survey from Consumer Reports shows several newer electric cars to be beset with problems, contradicting the conventional wisdom that EVs with their simpler powertrains should have fewer issues than gasoline- or diesel-powered cars. The CR reader survey harvested data on some 329,000 vehicles and specifically calls out the Audi E-Tron, the Kia Niro EV, and the Tesla Model Y. The E-Tron is dinged for "drive-system electrical failures along with other power-equipment issues." The Niro EV's problems reportedly included electric-motor bearing failure. The Tesla suffers a panoply of build-quality issues include misaligned body panels and poor paint quality. Both Audi and Kia claimed to be aware of the issues. For now, though, CR has removed the E-Tron and the Niro EV from its Recommended list (which is based on vehicle test results as well as reliability). The Model Y was not on the Recommended list. CR notes that some older, less-complicated EVs did well in the reliability survey, including the Chevrolet Bolt and the Nissan Leaf. More controversially, as a result of this latest survey's findings, Consumer Reports has decided to downgrade the predicted reliability of several new EVs that were not even included in the survey, including the Ford Mustang Mach-E, the Mercedes-Benz EQC, and the Porsche Taycan. "Often, it's not the EV tech that's problematic," says Anita Lam, CR's associate director of automotive data integration. "It's all the other new technology that could show up on any car -- new infotainment systems, more sophisticated power equipment and gadgets -- that often gets put on new EVs to feed a perception that they're supposed to be luxurious and high-tech."

An anonymous reader quotes a report from Music Business Worldwide: According to a document published last week, Daniel Ek's company is seeking a patent for its "Plagiarism Risk Detector And Interface" technology, which pertains to "Methods, systems and computer program products..for testing a lead sheet for plagiarism." As explained in the filing -- and as our songwriter/musician readers will already know -- a "lead sheet" is a type of music score or musical notation for songs denoting their melody, chords and sometimes lyrics or additional notes. Spotify's invention would allow for a lead sheet to be fed through the platform's "plagiarism detector," which would then, "having been trained on a plurality of preexisting encoded lead sheets," immediately compare the composition in question to all other songs stored in its database. A set of messages would then be displayed -- describing a detected level of plagiarism regarding "a plurality of elements" such as a chord sequence, melodic fragments, harmony, etc. of a song. The AI software would also potentially calculate "a similarity value" of the song in question vs. other songs in the Spotify lead sheet library. These technology could work the other way around, too, says Spotify's filing, reassuring a songwriter that "the melodic fragment [of your song] appears to be completely new." One particularly interesting element of this is that it would take place in near-real time, allowing a songwriter or composer to tweak elements of their work to avoid infringement before they (and/or their record label) spent the big bucks on recording a final version. Spotify's filing adds that "in some embodiments a link to the media content item that might be infringed (e.g., a track of an album) is provided so that a [songwriter] can quickly... listen to the potentially plagiarized work."

Google News Showcase visitors will soon be able to read select paywalled articles at no extra charge. TechCrunch reports: Google says it will be paying participating publishers to provide "limited access to paywalled content for News Showcase users." Those users will, however, still need to register directly with the publishers, which Google says will give them a way to build a relationship. The main News Showcase format is essentially story panel, and Google says it's introducing a new panel allowing publishers to curate a daily selection of their most important stories. Those panels will be shown to users who follow those publishers. Google is also bringing the News Showcase to new devices and channels. It started out on Google News on Android and is now available on iOS as well, with plans to expand to the news.google.com website and Discover soon. And it says it has doubled the number of partners since the launch in October -- the list of nearly 400 publishers participating in the program includes new names like Le Monde, Courrier International, L'Obs, Le Figaro, Liberation and L'Express in France, plus Pagina12, La Gaceta and El Dia in Argentina.
