U.S. authorities consider DJI a security threat. Congress is weighing legislation to ban it [non-paywalled link], prompting a lobbying campaign from the company, which dominates the commercial and consumer drone markets. The New York Times: DJI is on a Defense Department list of Chinese military companies whose products the U.S. armed forces will be prohibited from purchasing in the future. As part of the defense budget that Congress passed for this year, other federal agencies and programs are likely to be prohibited from purchasing DJI drones as well. The drones -- though not designed or authorized for combat use -- have also become ubiquitous in Russia's war against Ukraine.

The Treasury and Commerce Departments have penalized DJI over the use of its drones for spying on Uyghur Muslims who are held in camps by Chinese officials in the Xinjiang region. Researchers have found that Beijing could potentially exploit vulnerabilities in an app that controls the drone to gain access to large amounts of personal information, although a U.S. official said there are currently no known vulnerabilities that have not been patched. Now Congress is weighing legislation that could kill much of DJI's commercial business in the United States by putting it on a Federal Communications Commission roster blocking it from running on the country's communications infrastructure.

The bill, which has bipartisan support, has been met with a muscular lobbying campaign by DJI. The company is hoping that Americans like Mr. Nordfors who use its products will help persuade lawmakers that the United States has nothing to fear -- and much to gain -- by keeping DJI drones flying. "DJI presents an unacceptable national security risk, and it is past time that drones made by Communist China are removed from America," Representative Elise Stefanik, Republican of New York and one of the bill's primary sponsors, said in an emailed statement this month.

Europe is less hard-working, less ambitious, more regulated and more risk-averse than the US, according to the boss of Norway's giant oil fund, with the gap between the two continents only getting wider. FT: Nicolai Tangen, chief executive of the $1.6tn fund, told the Financial Times it was "worrisome" that American companies were outpacing their European rivals [non paywalled link] on innovation and technology, leading to vast outperformance of US shares in the past decade. "There's a mindset issue in terms of acceptance of mistakes and risks. You go bust in America, you get another chance. In Europe, you're dead," he said, adding that there was also a difference in "the general level of ambition. We are not very ambitious. I should be careful about talking about work-life balance, but the Americans just work harder."

His views are significant as the oil fund is one of the largest single investors in the world, owning on average 1.5 per cent of every listed company globally and 2.5 per cent of every European equity. Its US holdings have increased in the past decade while its European ones have declined. US shares account for almost half of all its equities compared with 32 per cent in 2013. The leading European country -- the UK -- represented 15 per cent of its equity portfolio a decade ago but just 6 per cent last year.

Microsoft releases one of the most popular versions of MS-DOS as open source today. stikves shares a post:Ten years ago, Microsoft released the source for MS-DOS 1.25 and 2.0 to the Computer History Museum, and then later republished them for reference purposes. This code holds an important place in history and is a fascinating read of an operating system that was written entirely in 8086 assembly code nearly 45 years ago.

Today, in partnership with IBM and in the spirit of open innovation, we're releasing the source code to MS-DOS 4.00 under the MIT license. There's a somewhat complex and fascinating history behind the 4.0 versions of DOS, as Microsoft partnered with IBM for portions of the code but also created a branch of DOS called Multitasking DOS that did not see a wide release.

Thomas Claburn reports via The Register: Baltimore police have arrested Dazhon Leslie Darien, the former athletic director of Pikesville High School (PHS), for allegedly impersonating the school's principal using AI software to make it seem as if he made racist and antisemitic remarks. Darien, of Baltimore, Maryland, was subsequently charged with witness retaliation, stalking, theft, and disrupting school operations. He was detained late at night trying to board a flight at BWI Thurgood Marshall Airport. Security personnel stopped him because the declared firearm he had with him was improperly packed and an ensuing background check revealed an open warrant for his arrest.

"On January 17, 2024, the Baltimore County Police Department became aware of a voice recording being circulated on social media," said Robert McCullough, Chief of Baltimore County Police, at a streamed press conference today. "It was alleged the voice captured on the audio file belong to Mr Eric Eiswert, the Principal at the Pikesville High School. We now have conclusive evidence that the recording was not authentic. "The Baltimore County Police Department reached that determination after conducting an extensive investigation, which included bringing in a forensic analyst contracted with the FBI to review the recording. The results of the analysis indicated the recording contained traces of AI-generated content." McCullough said a second opinion from a forensic analyst at the University of California, Berkeley, also determined the recording was not authentic. "Based off of those findings and further investigation, it's been determined the recording was generated through the use of artificial intelligence technology," he said.

According to the warrant issued for Darien's arrest, the audio file was shared through social media on January 17 after being sent via email to school teachers. The recording sounded as if Principal Eric Eiswert had made remarks inflammatory enough to prompt a police visit to advise on protective security measures for staff. [...] The clip, according to the warrant, led to the temporary removal of Eiswert from his position and "a wave of hate-filled messages on social media and numerous calls to the school," and significantly disrupted school operations. Police say it led to threats against Eiswert and concerns about his safety. Eiswert told investigators that he believes the audio clip was fake as "he never had the conversations in the recording." And he said he believed Darien was responsible due to his technical familiarity with AI and had a possible motive: Eiswert said there "had been conversations with Darien about his contract not being renewed next semester due to frequent work performance challenges." "It is clear that we are also entering a new deeply concerning frontier as we continue to embrace emerging technology and its potential for innovation and social good," said John Olszewski, Baltimore County Executive, during a press conference. "We must also remain vigilant against those who would have used it for malicious intent. That will require us to be more aware and more discerning about the audio we hear and the images we see. We will need to be careful in our judgment."

An anonymous reader quotes a report from TorrentFreak: Late January, the U.S. Department of Commerce published a notice of proposed rulemaking for establishing new requirements for Infrastructure as a Service providers (IaaS) . The proposal boils down to a 'Know Your Customer' regime for companies operating cloud services, with the goal of countering the activities of "foreign malicious actors." Yet, despite an overseas focus, Americans won't be able to avoid the proposal's requirements, which covers CDNs, virtual private servers, proxies, and domain name resolution services, among others. [...] Under the proposed rule, Customer Identification Programs (CIPs) operated by IaaS providers must collect information from both existing and prospective customers, i.e. those at the application stage of opening an account. The bare minimum includes the following data: a customer's name, address, the means and source of payment for each customer's account, email addresses and telephone numbers, and IP addresses used for access or administration of the account.

What qualifies as an IaaS is surprisingly broad: "Any product or service offered to a consumer, including complimentary or "trial" offerings, that provides processing, storage, networks, or other fundamental computing resources, and with which the consumer is able to deploy and run software that is not predefined, including operating systems and applications. The consumer typically does not manage or control most of the underlying hardware but has control over the operating systems, storage, and any deployed applications. The term is inclusive of "managed" products or services, in which the provider is responsible for some aspects of system configuration or maintenance, and "unmanaged" products or services, in which the provider is only responsible for ensuring that the product is available to the consumer."

And it doesn't stop there. The term IaaS includes all 'virtualized' products and services where the computing resources of a physical machine are shared, such as Virtual Private Servers (VPS). It even covers 'baremetal' servers allocated to a single person. The definition also extends to any service where the consumer does not manage or control the underlying hardware but contracts with a third party for access. "This definition would capture services such as content delivery networks, proxy services, and domain name resolution services," the proposal reads. The proposed rule, National Emergency with Respect to Significant Malicious Cyber-Enabled Activities, will stop accepting comments from interested parties on April 30, 2024.

Jeff Lawson, the cofounder of cloud computing company Twilio, appears to have purchased the satirical news website The Onion from G/O Media. Business Insider reports: A trust linked to Lawson is behind a San Francisco-based company called Global Tetrahedron, which shares the name of a fictional evil megacorporation in a long-running Onion gag, business records show. G/O Media CEO Jim Spanfeller confirmed the sale of The Onion to Global Tetrahedron in an email Thursday to staff, first reported by New York Times journalist Katie Robertson.

"This company is made up of four digital media veterans with a profound love for The Onion and comedy based content," Spanfeller wrote. "The site's new owners have agreed to keep The Onion's entire staff intact and in Chicago, something we insisted be part of the deal." When asked about the purchase, Lawson replied: "What's The Onion?" Then, "What's a Tetrahedron?"

Fintech giant Stripe announced on Thursday that it would let customers accept cryptocurrency payments, starting with USDC stablecoins, initially only on Solana, Ethereum and Polygon. TechCrunch reports: This will be the first time that Stripe has taken crypto payments since 2018, when it dropped support for Bitcoin due to it being too unstable. Stripe in 2022 tried its first reentry into the crypto market when it announced payouts (but not payments) in USDC, with Twitter as its marquee customer for the service. Thursday's news has no customer names attached to it.

On Wednesday the company unveiled a long list of other launches, the most significant update being that Stripe, for the very first time, would let customers integrate competing payment providers with Stripe's other financial services tooling. Thursday's nod to expanding crypto support is also part of that bigger strategy to open up its walled garden. A brief timeline of Stripe's dance with crypto underscores the tricky line that Stripe has walked over the years when it comes to cryptocurrency. True to its disruptive roots as a fintech, the company has wanted to be in the middle of the conversation around how blockchain-based technologies will affect financial services. But it runs the risk of subverting its bigger business and positioning as a stable and sensible financial powerhouse if it dabbles too deeply or for too long in periods of instability. The company processed $1 trillion in transactions last year, and it's still growing; it is currently worth $65 billion on paper.

Coal-fired power plants would be forced to capture smokestack emissions or shut down under a rule issued on Thursday by the Environmental Protection Agency (EPA). From a report: New limits on greenhouse gas emissions from fossil fuel-fired electric plants are the Biden administration's most ambitious effort yet to roll back planet-warming pollution from the power sector, the nation's second-largest contributor to the climate crisis. The rules are a key part of Joe Biden's pledge to eliminate carbon pollution from the electricity sector by 2035 and economy-wide by 2050.

The rule was among four separate measures targeting coal and natural gas plants that the EPA said would provide "regular certainty" to the power industry and encourage them to make investments to transition "to a clean energy economy." They also include requirements to reduce toxic wastewater pollutants from coal-fired plants and to safely manage so-called coal ash in unlined storage ponds. The new rules "reduce pollution from fossil fuel-fired power plants, protect communities from pollution and improve public health -- all while supporting the long-term, reliable supply of the electricity needed to power America forward," the EPA administrator, Michael Regan, told reporters at a White House briefing.

An anonymous reader quotes a report from CNN: The fertility rate in the United States has been trending down for decades, and a new report shows that another drop in births in 2023 brought the rate down to the lowest it's been in more than century. There were about 3.6 million babies born in 2023, or 54.4 live births for every 1,000 females ages 15 to 44, according to provisional data from the US Centers for Disease Control and Prevention's National Center for Health Statistics. After a steep plunge in the first year of the Covid-19 pandemic, the fertility rate has fluctuated. But the 3% drop between 2022 and 2023 brought the rate just below the previous low from 2020, which was 56 births for every 1,000 women of reproductive age.

The birth rate fell among most age groups between 2022 and 2023, the new report shows. The teen birth rate reached another record low of 13.2 births per 1,000 females ages 15 to 19, which is 79% lower than it was at the most recent peak from 1991. However, the rate of decline was slower than it's been for the past decade and a half. Meanwhile, births continued to shift to older mothers. Older age groups saw smaller decreases in birth rates, and the birth rate was highest among women ages 30 to 34 -- with about 95 births for every 1,000 women in this group in 2023. Women 40 and older were the only group to see an increase in birth rate, although -- at less than 13 births for every 1,000 women -- it remained lower than any other age group.

An international team of scientists used 1.8 billion letters of genetic code from more than 9,500 species covering almost 8,000 known flowering plant genera to create the most up-to-date understanding of the flowering plant tree of life. The research has been published in the journal Nature. Phys.Org reports: The major milestone for plant science, led by [Royal Botanic Gardens, Kew] and involving 138 organizations internationally, was built on 15 times more data than any comparable studies of the flowering plant tree of life. Among the species sequenced for this study, more than 800 have never had their DNA sequenced before. The sheer amount of data unlocked by this research, which would take a single computer 18 years to process, is a huge stride towards building a tree of life for all 330,000 known species of flowering plants -- a massive undertaking by Kew's Tree of Life Initiative.

The flowering plant tree of life, much like our own family tree, enables us to understand how different species are related to each other. The tree of life is uncovered by comparing DNA sequences between different species to identify changes (mutations) that accumulate over time like a molecular fossil record. Our understanding of the tree of life is improving rapidly in tandem with advances in DNA sequencing technology. For this study, new genomic techniques were developed to magnetically capture hundreds of genes and hundreds of thousands of letters of genetic code from every sample, orders of magnitude more than earlier methods. A key advantage of the team's approach is that it enables a wide diversity of plant material, old and new, to be sequenced, even when the DNA is badly damaged. The vast treasure troves of dried plant material in the world's herbarium collections, which comprise nearly 400 million scientific specimens of plants, can now be studied genetically.

[...] Across all 9,506 species sequenced, more than 3,400 came from material sourced from 163 herbaria in 48 countries. Additional material from plant collections around the world (e.g., DNA banks, seeds, living collections) have been vital for filling key knowledge gaps to shed new light on the history of flowering plant evolution. The team also benefited from publicly available data for more than 1,900 species, highlighting value of the open science approach to future genomic research. Flowering plants alone account for about 90% of all known plant life on land and are found virtually everywhere on the planet -- from the steamiest tropics to the rocky outcrops of the Antarctic Peninsula. [...] Utilizing 200 fossils, the authors scaled their tree of life to time, revealing how flowering plants evolved across geological time. They found that early flowering plants did indeed explode in diversity, giving rise to more than 80% of the major lineages that exist today shortly after their origin. However, this trend then declined to a steadier rate for the next 100 million years until another surge in diversification about 40 million years ago, coinciding with a global decline in temperatures. These new insights would have fascinated Darwin and will surely help today's scientists grappling with the challenges of understanding how and why species diversify. A list of "remarkable species" included in the flowering plant tree of life is embedded below the article.

Looking ahead, the study's authors believe this data will aid future attempts to identify new species, refine plant classification, uncover new medicinal compounds, and conserve plants in the face of climate change and biodiversity loss.

Department of Transportation Secretary Pete Buttigieg announced new rules for the airline industry that will require airlines to automatically give cash refunds to passengers for canceled and significantly delayed flights. They will also require airlines to give cash refunds if your bags are lost and not delivered within 12 hours.

"This is a big day for America's flying public," said Buttigieg at a Wednesday morning news conference. According to Buttigieg, the new rules are the biggest expansion of passenger rights in the department's history. ABC News reports: Airlines can no longer decide how long a delay must be before a refund is issued. Under the new DOT rules, the delays covered would be more than three hours for domestic flights and more than six hours for international flights, the agency said. This includes tickets purchased directly from airlines, travel agents and third-party sites such as Expedia and Travelocity.

The refunds must be issued within seven days, according to the new DOT rules, and must be in cash unless the passenger chooses another form of compensation. Airlines can no longer issue refunds in forms of vouchers or credits when consumers are entitled to receive cash. Airlines will have six months to comply with the new rules.

The DOT said it is also working on rules related to family seating fees, enhancing rights for wheelchair-traveling passengers for safe and dignified travel and mandating compensation and amenities if flights are delayed or canceled by airlines. Buttigieg said the DOT is also protecting airline passengers from being surprised by hidden fees -- a move he estimates will have Americans billions of dollars every year. The DOT rules include that passengers will receive refunds for extra services paid for and not provided, such as Wi-Fi, seat selection or inflight entertainment.

Samantha Cole reports via 404 Media: A Japan-based online art platform is banning kink content for users based in the US and UK, as laws in these countries continue to tighten around sites that allow erotic content. Pixiv is an image gallery site where artists primarily share illustrations, manga, and novels. The site announced on April 22 that starting April 25, users whose account region is set to the US or UK will be subject to Pixiv's new terms of use, "Restrictions for Healthy Expression in Specific Countries and Regions."

The restrictions include several kinds of content that are illegal in the US, including sexualized depictions of minors and bestiality, as well as non-consensual depictions and deepfakes. But it also includes "content that appeals to the prurient interest, is patently offensive in light of community standards where you are located or where such content may be accessed or distributed, lacks serious literary, artistic, political, or scientific value, or otherwise violates any applicable obscenity laws, rules or regulations." This is an invocation of the Miller test, which determines non-constitutionally protected obscenity. "I'd never say this a few years ago, but it's my personal fear that the next step is most major internet hosting services implementing these policies on an infrastructure level," said an artist who goes by kradeelav. "My colleagues are certainly planning for it by specifically looking for kink-friendly hosts, to actually making homebrew servers themselves in worst-case scenarios."

An anonymous reader quotes a report from Ars Technica: Two researchers at the University of California, Davis -- Yanning Li and Alan Jenn -- have determined that nearly two-thirds of [California's] feeder lines don't have the capacity that will likely be needed for car charging. Updating to handle the rising demand might set its utilities back as much as 40 percent of the existing grid's capital cost. Li and Jenn aren't the first to look at how well existing grids can handle growing electric vehicle sales; other research has found various ways that different grids fall short. However, they have access to uniquely detailed data relevant to California's ability to distribute electricity (they do not concern themselves with generation). They have information on every substation, feeder line, and transformer that delivers electrons to customers of the state's three largest utilities, which collectively cover nearly 90 percent of the state's population. In total, they know the capacity that can be delivered through over 1,600 substations and 5,000 feeders.[...]

By 2025, only about 7 percent of the feeders will experience periods of overload. By 2030, that figure will grow to 27 percent, and by 2035 -- only about a decade away -- about half of the feeders will be overloaded. Problems grow a bit more slowly after that, with two-thirds of the feeders overloaded by 2045, a decade after all cars sold in California will be EVs. At that point, total electrical demand will be close to twice the existing capacity. The problems aren't evenly distributed, though. They appear first in high-population areas like the Bay Area. And throughout this period, most of the problems are in feeders that serve residential and mixed-use neighborhoods. The feeders that serve neighborhoods that are primarily business-focused don't see the same coordinated surge in demand that occurs as people get home from work and plug in; they're better able to serve the more erratic use of charging stations at office complexes and shopping centers. In terms of the grid, residential services will need to see their capacity expand by about 16 gigawatts by 2045. Public chargers will need nine gigawatts worth of added capacity by the same point. The one wild card is direct current fast charging. Eliminating fast chargers entirely would reduce the number of feeders that need upgrades by 12 percent. Converting all public stations to DC fast charging, in contrast, would boost that number by 15 percent. So the details of the upgrades that will be needed will be very sensitive to the impatience of EV drivers.

Paying for the necessary upgrades will be pricey, but there's a lot of uncertainty here. Li and Jenn came up with a range of anywhere between $6 billion and $20 billion. They put this in context in two ways. The total capital invested in the existing grid is estimated to be $51 billion, so the cost of updating it could be well over a third of its total value. At the same time, the costs will be spread out over decades and only total up to (at most) three times the grid's annual operation and maintenance costs. So in any one year, the costs shouldn't be crippling. All that might be expected to drive the cost of electricity up. But Li and Jenn suggest that the greater volume of electricity consumption will exert a downward pressure on prices (people will pay more overall but pay somewhat less per unit of electricity). Based on a few economic assumptions, the researchers conclude that this would roughly offset the costs of the necessary grid expansion, so the price per unit of electricity would be largely static. The findings have been published in the journal Proceedings of the National Academy of Sciences (PNAS).

President Joe Biden signed a foreign aid package that includes a bill that would ban TikTok if China-based parent company ByteDance fails to divest the app within a year. The Verge: The divest-or-ban bill is now law, starting the clock for ByteDance to make its move. The company has an initial nine months to sort out a deal, though the president could extend that another three months if he sees progress. While just recently the legislation seemed like it would stall out in the Senate after being passed as a standalone bill in the House, political maneuvering helped usher it through to Biden's desk. The House packaged the TikTok bill -- which upped the timeline for divestment from the six months allowed in the earlier version -- with foreign aid to US allies, which effectively forced the Senate to consider the measures together. The longer divestment period also seemed to get some lawmakers who were on the fence on board.
