The Biden administration is poised to open up a new front in its effort to safeguard U.S. AI from China with preliminary plans to place guardrails around the most advanced AI models, the core software of artificial intelligence systems like ChatGPT, Reuters reported Wednesday. From the report: The Commerce Department is considering a new regulatory push to restrict the export of proprietary or closed source AI models, whose software and the data it is trained on are kept under wraps, three people familiar with the matter said. Any action would complement a series of measures put in place over the last two years to block the export of sophisticated AI chips to China in an effort to slow Beijing's development of the cutting edge technology for military purposes. Even so, it will be hard for regulators to keep pace with the industry's fast-moving developments.

Currently, nothing is stopping U.S. AI giants like Microsoft-backed OpenAI, Alphabet's Google DeepMind and rival Anthropic, which have developed some of the most powerful closed source AI models, from selling them to almost anyone in the world without government oversight. Government and private sector researchers worry U.S. adversaries could use the models, which mine vast amounts of text and images to summarize information and generate content, to wage aggressive cyber attacks or even create potent biological weapons. To develop an export control on AI models, the sources said the U.S. may turn to a threshold contained in an AI executive order issued last October that is based on the amount of computing power it takes to train a model. When that level is reached, a developer must report its AI model development plans and provide test results to the Commerce Department.

An anonymous reader quotes a report from MSN: The US has revoked licenses allowing Huawei to buy semiconductors from Qualcomm and Intel, according to people familiar with the matter, further tightening export restrictions against the Chinese telecom equipment maker. Withdrawal of the licenses affects US sales of chips for use in Huawei phones and laptops, according to the people, who discussed the move on condition of anonymity. House Foreign Affairs Committee Chairman Michael McCaul confirmed the administration's decision in an interview Tuesday. He said the move is key to preventing China from developing advanced AI. "It's blocking any chips sold to Huawei," said McCaul, a Texas Republican who was briefed about the license decisions for Intel and Qualcomm. "Those are two companies we've always worried about being a little too close to China."

While the decision may not affect a significant volume of chips, it underscores the US government's determination to curtail China's access to a broad swathe of semiconductor technology. Officials are also considering sanctions against six Chinese firms that they suspect could supply chips to Huawei, which has been on a US trade restrictions list since 2019. [...] Qualcomm recently said that its business with Huawei is already limited and will soon shrink to nothing. It has been allowed to supply the Chinese company with chips that provide older 4G network connections. It's prohibited from selling ones that allow more advanced 5G access.

Computer models have found that recent heat waves in the north Pacific may be due to a large reduction in aerosols emitted by factories in China. The findings have been published in the Proceedings of the National Academy of Sciences. Phys.Org reports: In this new effort, the research team noted that the onset of the heat waves appeared to follow successful efforts by the Chinese government to reduce aerosol emissions from their country's factories. Beginning around 2010, factories and power generating plants in China began dramatically reducing emissions of aerosols such as sulfate, resulting in much cleaner air. Noting that aerosols can act like mirrors floating in the air, reflecting heat from the sun back into space, and also pointing out that earlier research efforts had suggested that massive reductions of aerosols in one place could lead to warming in other places -- they wondered if reductions of aerosols in China might be playing a role in the heat waves that began happening in the north Pacific.

To find out if that might be the case, the team began collecting data and then input it into 12 different computer climate models. They ran them under two conditions -- one where emissions from East Asia remained as they were over the past several decades and one where they dropped in the way they had in reality. They found that the models with no declines did not cause much change elsewhere, whereas those with aerosol drops showed heat waves occurring in the northeast parts of the Pacific Ocean.

The models also showed why -- as less heat was reflected back into space over China, warming of coastal regions in Asia began, resulting in the development of high-pressure systems. That in turn made low-pressure systems in the middle Pacific more intense. And that resulted in the Aleutian Low growing bigger and moving south which weakened the westerly winds that typically cool the sea surface. The result was hotter conditions.

Renewable energy accounted for more than 30% of the world's electricity for the first time last year, according to climate thinktank Ember. The Guardian reports: Clean electricity has already helped to slow the growth in fossil fuels by almost two-thirds in the past 10 years, according to the report by climate thinktank Ember. It found that renewables have grown from 19% of electricity in 2000 to more than 30% of global electricity last year. Solar was the main supplier of electricity growth, according to Ember, adding more than twice as much new electricity generation as coal in 2023. It was the fastest-growing source of electricity for the 19th consecutive year, and also became the largest source of new electricity for the second year running, after surpassing wind power.

The first comprehensive review of global electricity data covers 80 countries, which represent 92% of the world's electricity demand, as well as historic data for 215 countries. The surge in clean electricity is expected to power a 2% decrease in global fossil fuel generation in the year ahead, according to Ember. [...] World leaders are aiming to grow renewables to 60% of global electricity by 2030 under an agreement struck at the UN's Cop28 climate change conference in December. This would require countries to triple their current renewable electricity capacity in the next six years, which would almost halve power sector emissions.

Lawyers for the defunct cryptocurrency exchange FTX said customers would receive all the money they lost when the firm collapsed in 2022 and receive interest on top of it. "But the recoveries come with a caveat," reports the New York Times. "The amount owed to customers was calculated based on the value of their holdings at the time of FTX's bankruptcy in November 2022. That means customers won't reap the benefits of a recent surge in the crypto market that sent the price of Bitcoin to a record high." From the report: The announcement was a landmark in the attempt to recover the $8 billion in customer assets that disappeared when FTX imploded virtually overnight, setting off a crisis in the crypto industry. Under a plan filed in federal bankruptcy court in Delaware, virtually all FTX's creditors, including hundreds of thousands of ordinary investors who used the exchange to buy and sell cryptocurrencies, would receive cash payments equivalent to 118 percent of the assets they had stored on FTX, the lawyers said. Those payments would flow from a pool of assets that FTX's lawyers have pulled together in the 17 months since the exchange collapsed, the lawyers said. [...] It will take months for the payouts to begin. The plan must be approved by the federal judge overseeing FTX's bankruptcy, John T. Dorsey.

An anonymous reader quotes a report from Wired: Amazon plans to start flying delivery drones in Arizona this year -- but don't count on them to bring you a refreshing drink on a hot day. The hexacopter can't operate when temperatures top 104 degrees Fahrenheit, or 40 degrees Celsius, the company says, and average daily highs exceed that for three months of the year in Tolleson, the city outside Phoenix where Amazon is preparing to offer aerial deliveries from inside a 7.5-mile radius. The drones can't help with midnight snacks either, because they'll be grounded after sunset. Potentially being inoperable for a quarter of the year might make launching drone deliveries in Tolleson and neighboring desert communities seem like an odd choice. It's far from the first challenge faced by Amazon's much-delayed drone project. The unit is years behind its goals of flying items to customers in under an hour on a regular basis, and a one-time target of 500 million deliveries by 2030 seems distant. Amazon Prime Air has completed just thousands of deliveries, falling behind rivals; Alphabet subsidiary Wing has notched hundreds of thousands of delivery flights and Walmart more than 20,000.

In the California wine country town of Lockeford, where Amazon initially launched drone deliveries, some residents told WIRED last year that they ordered only because Amazon lured them with gift cards. In Arizona, it could be discouraging not being able to rely on drones during those hours when one might not want to venture too far from the comfort of air conditioning. [...] That temperature and other environmental conditions could ground or hamper the drone industry has been known for years. A team from University of Calgary's geography department estimated that on average across the world, drones with limitations similar to Amazon's, including from weather and daylight, would be limited to flying about 2 hours a day. In the world's 100 most populous cities, the average daily flight time would be 6 hours. "Weather is an important and poorly resolved factor that may affect ambitions to expand drone operations," they wrote in a study published in 2021. Heat, in particular, forces motors to work harder to keep drones aloft, and their batteries are only so powerful.

Wayve, a UK-based AI firm focused on developing self-driving car technology, has secured a record $1.05 billion in funding, with Microsoft and Nvidia participating in the round led by SoftBank. According to the BBC, this investment is the largest for an AI company in Europe. The BBC reports: Wayve says the funding will allow it to help build the autonomous cars of the future. [...] Wayve is developing technology intended to power future self-driving vehicles by using what it calls "embodied AI." Unlike AI models carrying out cognitive or generative tasks such as answering questions or creating pictures, this new technology interacts with and learns from real-world surroundings and environments. "[The investment] sends a crucial signal to the market of the strength of the UK's AI ecosystem, and we look forward to watching more AI companies here thrive and scale," said Wayve head Alex Kendall.

An anonymous reader shares a report: The Federal Aviation Administration is investigating whether Boeing failed to complete required inspections on 787 Dreamliner planes and whether Boeing employees falsified aircraft records, the agency said this week. The investigation was launched after an employee reported the problem to Boeing management, and Boeing informed the FAA. "The FAA has opened an investigation into Boeing after the company voluntarily informed us in April that it may not have completed required inspections to confirm adequate bonding and grounding where the wings join the fuselage on certain 787 Dreamliner airplanes," the FAA said in a statement provided to Ars today. The FAA said it "is investigating whether Boeing completed the inspections and whether company employees may have falsified aircraft records. At the same time, Boeing is reinspecting all 787 airplanes still within the production system and must also create a plan to address the in-service fleet." The agency added that it "will take any necessary action -- as always -- to ensure the safety of the flying public."

Boeing VP Scott Stocker, who leads the 787 Dreamliner program, described "misconduct" in an April 29 email to employees in South Carolina. Boeing provided a copy of the email to Ars. "After receiving the report, we quickly reviewed the matter and learned that several people had been violating Company policies by not performing a required test, but recording the work as having been completed," Stocker wrote. "As you all know, we have zero tolerance for not following processes designed to ensure quality and safety. We promptly informed our regulator about what we learned and are taking swift and serious corrective action with multiple teammates."

Less than two weeks after President Biden signed a bill that will force TikTok's Chinese owner, ByteDance, to sell the popular social media app or face a ban in the United States, TikTok said it sued the federal government on Tuesday, arguing the law was unconstitutional. From a report: TikTok said that the law violated the First Amendment by effectively removing an app that millions of Americans use to share their views and communicate freely. It also argued that a divestiture was "simply not possible," especially within the law's 270-day timeline, pointing to difficulties such as Beijing's refusal to sell a key feature that powers TikTok in the United States.

"For the first time in history, Congress has enacted a law that subjects a single, named speech platform to a permanent, nationwide ban, and bars every American from participating in a unique online community with more than one billion people worldwide," the company said in the 67-page petition it provided, which initiates the lawsuit. "There is no question: The act will force a shutdown of TikTok by Jan. 19, 2025." TikTok is battling for its survival in the United States, with the fight set to play out primarily in courts over the next few months. While lawmakers who passed the bill have said the app is a national security threat because of its ties to China, the courts must now weigh those concerns against TikTok's argument that a sale or ban would violate the First Amendment free-speech rights of its users and hurt small businesses that owe their livelihood to the platform.

The identity of the leader of one of the most infamous ransomware groups in history has finally been revealed. From a report: On Tuesday, a coalition of law enforcement led by the U.K.'s National Crime Agency announced that Russian national, Dmitry Yuryevich Khoroshev, 31, is the person behind the nickname LockBitSupp, the administrator and developer of the LockBit ransomware. The U.S. Department of Justice also announced the indictment of Khoroshev, accusing him of computer crimes, fraud and extortion.

"Today we are going a step further, charging the individual who we allege developed and administered this malicious cyber scheme, which has targeted over 2,000 victims and stolen more than $100 million in ransomware payments," Attorney General Merrick B. Garland was quoted as saying in the announcement. According to the DOJ, Khoroshev is from Voronezh, a city in Russia around 300 miles south of Moscow. "Dmitry Khoroshev conceived, developed, and administered Lockbit, the most prolific ransomware variant and group in the world, enabling himself and his affiliates to wreak havoc and cause billions of dollars in damage to thousands of victims around the globe," said U.S. Attorney Philip R. Sellinger for the District of New Jersey, where Khoroshev was indicted.

Swedish energy company Stockholm Exergi and Microsoft have announced a 10-year deal that will provide the tech giant with more than 3.3 million tons of carbon removal certificates through bioenergy with carbon capture and storage. While the value of the deal was not disclosed, it stands as the largest of its kind globally. Carbon Herald reports: Scheduled to commence in 2028 and span a decade, the agreement underscores a pivotal moment in combatting climate change. Anders Egelrud, CEO of Stockholm Exergi, lauded the deal as a "huge step" for the company and its BECCS project, emphasizing its profound implications for climate action. "I believe the agreement will inspire corporations with ambitious climate objectives, and we target to announce more deals with other pioneering companies over the coming months," he said. Recognizing the imperative of permanent carbon removals in limiting global warming to 1.5C or below, the deal aligns with Microsoft's ambitious goal of becoming carbon negative by 2030.

"Leveraging existing biomass power plants is a crucial first step to building worldwide carbon removal capacity," Brian Marrs, Microsoft's Senior Director of Energy & Carbon Removal, said, highlighting the importance of sustainable biomass sourcing for BECCS projects, as is the case with Stockholm Exergi. The partners will adhere to stringent quality standards, ensuring transparent reporting and adherence to sustainability criteria. The BECCS facility, once operational, will remove up to 800,000 tons of carbon dioxide (CO2) annually, contributing significantly to atmospheric carbon reduction. With environmental permits secured and construction set to commence in 2025, Stockholm Exergi plans to reach the final investment decision by the end of the year.

Shell sold millions of carbon credits tied to CO2 removal that never took place [non-paywalled link] to Canada's largest oil sands companies, raising new doubts about a technology seen as crucial to mitigating greenhouse gas emissions. FT: As part of a subsidy scheme to boost the industry, the Alberta provincial government allowed Shell to register and sell carbon credits equivalent to twice the volume of emissions avoided by its Quest carbon capture facility between 2015 and 2021, the province's registry shows. The subsidy was reduced and then ended in 2022.

As a result of the scheme, Shell was able to register 5.7mn credits that had no equivalent CO2 reductions, selling these to top oil sands producers and some of its own subsidiaries. Credits are typically equivalent to one tonne of CO2. Some of the largest buyers of the credits were Chevron, Canadian Natural Resources, ConocoPhillips, Imperial Oil and Suncor Energy. Keith Stewart, a senior energy strategist with Greenpeace Canada, criticised these "phantom credits." Stewart added: "Selling emissions credits for reductions that never happened ... literally makes climate change worse."

Shell said carbon capture played "an important role in helping to decarbonise industry and sectors where emissions cannot be avoided" and that realising its potential "requires creating market incentives now." Alberta's environment ministry said the crediting support scheme had not resulted in "additional emissions" by industrial polluters.

A council has provoked the wrath of residents and linguists alike after announcing it would ban apostrophes on street signs to avoid problems with computer systems. From a report: North Yorkshire council is ditching the punctuation point after careful consideration, saying it can affect geographical databases. The council said all new street signs would be produced without one, regardless of whether they were used in the past. Some residents expressed reservations about removing the apostrophes, and said it risked "everything going downhill." They urged the authority to retain them.

Sam, a postal worker in Harrogate, a spa town in North Yorkshire, told the BBC that signs missing an apostrophe -- such as the nearby St Mary's Walk sign that had been erected in the town without it -- infuriated her. "I walk past the sign every day and it riles my blood to see inappropriate grammar or punctuation," she said. Though the updated St Mary's sign had no apostrophe, someone had graffitied an apostrophe back on to the sign with a marker pen, which the former teacher said was "brilliant." She suggested the council was providing a bad example to children who spend a long time learning the basics of grammar only to see it not being used correctly on street signs.

Dr Ellie Rye, a lecturer in English language and linguistics at the University of York, said apostrophes were a relatively new invention in our writing and, often, context allows people to understand their meaning. "If I say I live on St Mary's Walk, we're expecting a street name or an address of some kind." She said the change would matter to people who spend a long time teaching how we write English but that it was "less important in [verbal] communication."

Poor countries must demonstrate clearer accounting and transparency to back up their calls for trillions of dollars of climate finance, the president of global climate negotiations has said. From a report: Mukhtar Babayev, the ecology minister of Azerbaijan, who will lead the Cop29 UN climate summit in November, urged governments in developing countries to draw up reports showing their progress on cutting greenhouse gas emissions, and their spending on the climate crisis. "It's very important to build this correct, good and honest trust between the parties," he said in an interview in Baku, the capital of Azerbaijan. "It's a very, very important step, the creation of a transparency mechanism between the countries."

At Cop29 in Baku, countries will be expected to come up with a new global goal on supplying climate finance to poorer countries, to help them cut their greenhouse gas emissions and adapt to the impacts of extreme weather. Some governments from the global south are calling for the sums to reach more than $1tn a year. These pledges are expected to be subject to bitter wrangling at Cop29, as rich countries are unlikely to agree to provide anything like such sums from their taxpayers but the role of other sources of finance -- such as the private sector -- is still in question.
