Deepfakes of Your Dead Loved Ones Are a Booming Chinese Business

Par : BeauHD
9 mai 2024 à 03:30
An anonymous reader quotes a report from MIT Technology Review: Once a week, Sun Kai has a video call with his mother. He opens up about work, the pressures he faces as a middle-aged man, and thoughts that he doesn't even discuss with his wife. His mother will occasionally make a comment, like telling him to take care of himself -- he's her only child. But mostly, she just listens. That's because Sun's mother died five years ago. And the person he's talking to isn't actually a person, but a digital replica he made of her -- a moving image that can conduct basic conversations. They've been talking for a few years now. After she died of a sudden illness in 2019, Sun wanted to find a way to keep their connection alive. So he turned to a team at Silicon Intelligence, an AI company based in Nanjing, China, that he cofounded in 2017. He provided them with a photo of her and some audio clips from their WeChat conversations. While the company was mostly focused on audio generation, the staff spent four months researching synthetic tools and generated an avatar with the data Sun provided. Then he was able to see and talk to a digital version of his mom via an app on his phone. "My mom didn't seem very natural, but I still heard the words that she often said: 'Have you eaten yet?'" Sun recalls of the first interaction. Because generative AI was a nascent technology at the time, the replica of his mom can say only a few pre-written lines. But Sun says that's what she was like anyway. "She would always repeat those questions over and over again, and it made me very emotional when I heard it," he says. There are plenty of people like Sun who want to use AI to preserve, animate, and interact with lost loved ones as they mourn and try to heal. The market is particularly strong in China, where at least half a dozen companies are now offering such technologies and thousands of people have already paid for them. In fact, the avatars are the newest manifestation of a cultural tradition: Chinese people have always taken solace from confiding in the dead. The technology isn't perfect -- avatars can still be stiff and robotic -- but it's maturing, and more tools are becoming available through more companies. In turn, the price of "resurrecting" someone -- also called creating "digital immortality" in the Chinese industry -- has dropped significantly. Now this technology is becoming accessible to the general public. Some people question whether interacting with AI replicas of the dead is actually a healthy way to process grief, and it's not entirely clear what the legal and ethical implications of this technology may be. For now, the idea still makes a lot of people uncomfortable. But as Silicon Intelligence's other cofounder, CEO Sima Huapeng, says, "Even if only 1% of Chinese people can accept [AI cloning of the dead], that's still a huge market."

Dell Makes Return-To-Office Push With VPN, Badge Tracking

Dell is making sure its employees follow the company's updated return-to-office policy through a series of new tracking techniques. According to The Register, Dell will track employees' badge swipes and VPN connections and include a color-coded attendance grading system that summarizes employee presence. "In the latest Jeff Clarke return-to-grade-school initiative, HR will be keeping an attendance report card on employees, grading them at four levels based on how well they meet the goal of being in the office 39 days a quarter," a source familiar with Dell told The Register, referring to the IT giant's chief operating officer. "Employees who do not meet the attendance requirement will have their status escalated up the ladder to Jeff Clarke, who apparently believes that being a hall monitor trumps growing revenue." From the report: Starting next Monday, May 13, the enterprise hardware slinger plans to make weekly site visit data from its badge tracking available to employees through the corporation's human capital management software and to give them color-coded ratings that summarize their status. Those ratings are: Blue flag indicates "consistent onsite presence"; Green flag indicates "regular onsite presence"; Yellow flag indicates "some onsite presence"; Red flag indicates "limited onsite presence". A second Dell source explained managers aren't on the same page about the consequences of the color tiers, with some bosses suggesting employees want to remain Blue at all times and others indicating there's more leeway and they could put up with a few red flags. "It's a shit show here," we're told. [...] "Dell is tracking badge-ins and VPN connections to ensure employees are onsite when they claim they are (to deter 'coffee badging' or scanning your badge then going immediately home)," a third source told us. "This is likely in response to the official numbers about how many of our staff members chose to remain remote after the RTO mandate." [...] We're told that the goal of the worker tracking appears to be workforce attrition. "The problem is the market is soft right now for tech," our second source, pointing to recent AWS job cuts. "Everyone is laying off." This person anticipates further Dell layoffs over the summer, though no dates have been set. Our third source indicated that the onsite tracking policy seems unusually aggressive for Dell. "Even pre-pandemic, they never pushed or pressured folks to be in the office," this person said. "A common phrase used to be 'Work happens where you make it,' with the office often being a ghost town multiple times a week, or after lunch, or pre-holidays." Dell in February reported fiscal year 2024 revenue of $88.4 billion, down 14 percent from 2023, and profits of $3.2 billion.

Google announced on Tuesday that it will be exiting One Market Plaza, a prominent office complex in San Francisco that it had been occupying since 2018. The company's lease for the 300,000-square-foot-office will expire next April. The San Francisco Chronicle reports: Many of Google's employees are already working outside of the giant waterfront office, in light of the company's flexible approach to office attendance. As one of the city's largest office properties and a prominent feature on its skyline, the 1.6-million-square-foot One Market Plaza complex features two high-rise towers and a 11-story office annex building known as the Landmark." Ryan Lamont, a spokesperson for Google, said the company will be moving out of One Market's Spear Tower, but will continue to occupy the smaller Landmark building. He declined to comment on how long Google plans to remain in the latter." As we've said before, we're focused on investing in real estate efficiently to meet the current and future needs of our hybrid workforce," Lamont said in an email to the Chronicle. "We remain committed to our long-term presence in San Francisco." Real estate market participants who spoke with the Chronicle indicated that Google plans to consolidate much of its operations from One Market to nearby 345 Spear St., where the company leases about 400,000 square feet. These individuals said that Google will likely renew its lease at that property once it expires next year.

81% of Young People Say a 4-Day Workweek Would Boost Productivity, Survey Finds

9 mai 2024 à 00:45
A new national survey (PDF) from CNBC/Generation Lab of 1,033 people aged 18 to 34 found that an overwhelming 81% of respondents believe a four-day workweek would boost their company's productivity, while 19% said productivity would decline. CNBC reports: Those results from the "Youth & Money in the USA" survey come amid discussions around the potential benefits of switching from the standard five-day U.S. workweek to a four-day cadence without a pay cut. Some companies have begun testing the arrangement, and say it has mitigated employee burnout and strengthened business performance. Exos, a U.S. coaching company that trains top athletes and leads corporate wellness programs, recently reported results from the first six months of an ongoing four-day workweek experiment. The company said the shortened workweek increased efficiency along with revenue and retention. Although respondents to the CNBC/Generation Lab survey largely agreed on workweek length, they were less unified when asked about work setting. A 60% majority said they do their best work in the office, while the other 40% said they do so at home. Further reading: 32-Hour Workweek for America Proposed by Senator Bernie Sanders

Ransomware Crooks Now SIM Swap Executives' Kids To Pressure Their Parents

Par : BeauHD
9 mai 2024 à 00:02
An anonymous reader quotes a report from The Register: Ransomware infections have morphed into "a psychological attack against the victim organization," as criminals use increasingly personal and aggressive tactics to force victims to pay up, according to Google-owned Mandiant. "We saw situations where threat actors essentially SIM swap the phones of children of executives, and start making phone calls to executives, from the phone numbers of their children," Charles Carmakal, Mandiant's CTO, recounted during a Google Security Threat Intelligence Panel at this year's RSA Conference in San Francisco on Monday. "Think about the psychological dilemma that the executive goes through – seeing a phone call from the children, picking up the phone and hearing that it's somebody else's voice? Sometimes, it's caller ID spoofing. Other times, we see demonstrated SIM swapping family members." Either way, it's horrifying. It's the next step in the evolution of ransomware tactics, which have now moved far beyond simply encrypting victims' files and even stealing their data. "There are a few threat actors that really have no rules of engagement in terms of how far [they] try to coerce victims," Carmakal noted, recalling ransomware incidents in which the criminals have directly contacted executives, their family members, and board members at their homes. The criminals have moved from just staging an attack against a company, its customers and their data, and becomes "more against the people," he added. It changes the calculation involved in deciding whether to pay the extortion demand, Carmakal said. "It's less about 'do I need to protect my customers?' But more about 'how do I better protect my employees and protect the families of employees?' That's a pretty scary shift."

US Libraries Are Battling High Prices For Better E-Book Access

Par : BeauHD
8 mai 2024 à 23:20
Librarians are fighting a nationwide battle against high e-book prices, which so far has yielded minimal results. Despite efforts and temporary legislative victories, strict renewal and loan policies imposed by publishers keep e-book costs high, limiting the number of popular titles libraries can offer and leading to frustration among patrons. Axios reports: Publishers typically require libraries to renew the license to each e-book every two years, or after 26 loans -- policies that libraries call prohibitively expensive. This restricts the number of e-books -- particularly popular bestsellers -- that they can lend out to patrons, who are angry and baffled by the limitations. Readers love the free (to them) apps that allow them to borrow countless e-books and audiobooks: Libby (the dominant one, run by OverDrive) and hoopla. But some libraries say that the cost of renewing their contracts with OverDrive and hoopla are prohibitive, so they're dropping the apps -- hoopla in particular. The Association of American Publishers argues that it must protect the rights of copyright owners -- that is, authors -- to be fairly compensated for their work. hoopla and Libby say they're just the middlemen. "It's really not up to us, to be honest," Ann Ford, a vice president at hoopla, tells Axios. "It's the publishers that make the rules." Libraries have a "unique and determinative public mission" that should entitle them to more favorable e-book purchasing terms when using public funds, says Kyle Courtney, a lawyer and Harvard librarian who drafted model e-book legislation for states. "These are nonnegotiable contracts, and the libraries have been trying to get a deal for years. We need the coercive power of the state sitting behind us at the table saying, 'We need a special slice of the pie.'"

FCC Explicitly Prohibits Fast Lanes, Closing Possible Net Neutrality Loophole

Par : BeauHD
8 mai 2024 à 22:00
An anonymous reader quotes a report from Ars Technica: The Federal Communications Commission clarified its net neutrality rules to prohibit more kinds of fast lanes. While the FCC voted to restore net neutrality rules on April 25, it didn't release the final text of the order until yesterday. The final text (PDF) has some changes compared to the draft version released a few weeks before the vote. Both the draft and final rules ban paid prioritization, or fast lanes that application providers have to pay Internet service providers for. But some net neutrality proponents raised concerns about the draft text because it would have let ISPs speed up certain types of applications as long as the application providers don't have to pay for special treatment. The advocates wanted the FCC to clarify its no-throttling rule to explicitly prohibit ISPs from speeding up applications instead of only forbidding the slowing of applications down. Without such a provision, they argued that ISPs could charge consumers more for plans that speed up specific types of content. [...] "We clarify that a BIAS [Broadband Internet Access Service] provider's decision to speed up 'on the basis of Internet content, applications, or services' would 'impair or degrade' other content, applications, or services which are not given the same treatment," the FCC's final order said. The "impair or degrade" clarification means that speeding up is banned because the no-throttling rule says that ISPs "shall not impair or degrade lawful Internet traffic on the basis of Internet content, application, or service." The updated language in the final order "clearly prohibits ISPs from limiting fast lanes to apps or categories of apps they select," leaving no question as to whether the practice is prohibited, said Stanford Law professor Barbara van Schewick. Under the original plan, "there was no way to predict which kinds of fast lanes the FCC might ultimately find to violate the no-throttling rule," she wrote. "This would have given ISPs cover to flood the market with various fast-lane offerings, arguing that their version does not violate the no-throttling rule and daring the FCC to enforce its rule. The final order prevents this from happening."

US Revokes Intel, Qualcomm Licenses To Sell Chips To Huawei

Par : BeauHD
8 mai 2024 à 13:00
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.

Heat Waves In North Pacific May Be Due To China Reducing Aerosols

Par : BeauHD
8 mai 2024 à 10:00
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 Passes 30% of World's Electricity Supply

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.

FTX Customers Poised to Recover All Funds Lost in Collapse

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.

Defense Think Tank MITRE To Build AI Supercomputer With Nvidia

8 mai 2024 à 03:30
An anonymous reader quotes a report from the Washington Post: A key supplier to the Pentagon and U.S. intelligence agencies is building a $20 million supercomputer with buzzy chipmaker Nvidia to speed deployment of artificial intelligence capabilities across the U.S. federal government, the MITRE think tank said Tuesday. MITRE, a federally funded, not-for-profit research organization that has supplied U.S. soldiers and spies with exotic technical products since the 1950s, says the project could improve everything from Medicare to taxes. "There's huge opportunities for AI to make government more efficient," said Charles Clancy, senior vice president of MITRE. "Government is inefficient, it's bureaucratic, it takes forever to get stuff done. ... That's the grand vision, is how do we do everything from making Medicare sustainable to filing your taxes easier?" [...] The MITRE supercomputer will be based in Ashburn, Va., and should be up and running late this year. [...] Clancy said the planned supercomputer will run 256 Nvidia graphics processing units, or GPUs, at a cost of $20 million. This counts as a small supercomputer: The world's fastest supercomputer, Frontier in Tennessee, boasts 37,888 GPUs, and Meta is seeking to build one with 350,000 GPUs. But MITRE's computer will still eclipse Stanford's Natural Language Processing Group's 68 GPUs, and will be large enough to train large language models to perform AI tasks tailored for government agencies. Clancy said all federal agencies funding MITRE will be able to use this AI "sandbox." "AI is the tool that is solving a wide range of problems," Clancy said. "The U.S. military needs to figure out how to do command and control. We need to understand how cryptocurrency markets impact the traditional banking sector. ... Those are the sorts of problems we want to solve."

Study Suggests Genetics as a Cause, Not Just a Risk, for Some Alzheimer's

Par : BeauHD
8 mai 2024 à 02:02
Pam Belluck reports via the New York Times: Scientists are proposing a new way of understanding the genetics of Alzheimer's that would mean that up to a fifth of patients would be considered to have a genetically caused form of the disease. Currently, the vast majority of Alzheimer's cases do not have a clearly identified cause. The new designation, proposed in a study published Monday, could broaden the scope of efforts to develop treatments, including gene therapy, and affect the design of clinical trials. It could also mean that hundreds of thousands of people in the United States alone could, if they chose, receive a diagnosis of Alzheimer's before developing any symptoms of cognitive decline, although there currently are no treatments for people at that stage. The new classification would make this type of Alzheimer's one of the most common genetic disorders in the world, medical experts said. "This reconceptualization that we're proposing affects not a small minority of people," said Dr. Juan Fortea, an author of the study and the director of the Sant Pau Memory Unit in Barcelona, Spain. "Sometimes we say that we don't know the cause of Alzheimer's disease," but, he said, this would mean that about 15 to 20 percent of cases "can be tracked back to a cause, and the cause is in the genes." The idea involves a gene variant called APOE4. Scientists have long known that inheriting one copy of the variant increases the risk of developing Alzheimer's, and that people with two copies, inherited from each parent, have vastly increased risk. The new study, published in the journal Nature Medicine, analyzed data from over 500 people with two copies of APOE4, a significantly larger pool than in previous studies. The researchers found that almost all of those patients developed the biological pathology of Alzheimer's, and the authors say that two copies of APOE4 should now be considered a cause of Alzheimer's -- not simply a risk factor. The patients also developed Alzheimer's pathology relatively young, the study found. By age 55, over 95 percent had biological markers associated with the disease. By 65, almost all had abnormal levels of a protein called amyloid that forms plaques in the brain, a hallmark of Alzheimer's. And many started developing symptoms of cognitive decline at age 65, younger than most people without the APOE4 variant.

OpenAI Exec Says Today's ChatGPT Will Be 'Laughably Bad' In 12 Months

At the 27th annual Milken Institute Global Conference on Monday, OpenAI COO Brad Lightcap said today's ChatGPT chatbot "will be laughably bad" compared to what it'll be capable of a year from now. "We think we're going to move toward a world where they're much more capable," he added. Business Insider reports: Lightcap says large language models, which people use to help do their jobs and meet their personal goals, will soon be able to take on "more complex work." He adds that AI will have more of a "system relationship" with users, meaning the technology will serve as a "great teammate" that can assist users on "any given problem." "That's going to be a different way of using software," the OpenAI exec said on the panel regarding AI's foreseeable capabilities. In light of his predictions, Lightcap acknowledges that it can be tough for people to "really understand" and "internalize" what a world with robot assistants would look like. But in the next decade, the COO believes talking to an AI like you would with a friend, teammate, or project collaborator will be the new norm. "I think that's a profound shift that we haven't quite grasped," he said, referring to his 10-year forecast. "We're just scratching the surface on the full kind of set of capabilities that these systems have," he said at the Milken Institute conference. "That's going to surprise us."

Minor Car Crashes Mean High Tech Repairs

Par : BeauHD
8 mai 2024 à 00:45
"With all the improvements in car safety over the decades, the recent addition of a plethora of high tech sensors and warnings comes with increased costs," writes longtime Slashdot reader smooth wombat. "And not just to have to have them on your car. Any time you get into an accident, even a minor one, it will most likely require a detailed examination of any sensors which may have been affected and their subsequent realignment, replacement, and calibration." CNN reports: Some vehicles require "dynamic calibration," which means, once the sensors and cameras are back in place, a driver needs to take the vehicle out on real roads for testing. With proper equipment attached the car can, essentially, recalibrate itself as it watches lane lines and other markers. It requires the car to be driven for a set distance at a certain speed but weather and traffic can create problems. "If you're in Chicago or L.A., good luck getting to that speed," said [Hami Ebrahimi, chief commercial officer at Caliber] "or if you're in Seattle or Chicago or New York, with snow, good luck picking up all the road markings." More commonly, vehicles need "static calibration," which can be done using machinery inside a closed workshop with a flat, level floor. Special targets are set up around the vehicle at set distances according to instructions from the vehicle manufacturer. "The car [views] those targets at those specific distances to recalibrate the world into the car's computer," Ebrahimi said. These kinds of repairs also demand buildings with open space that meet requirements including specific colors and lighting. And it requires special training for employees to perform these sorts of recalibrations, he said "The change that we've seen in the last five years is greater than we've seen, probably, in the last five decades," said Todd Dillender, chief operating officer of Caliber Collision, one of the biggest auto body repair companies in the United States with more than 1,700 locations across 41 states. [...] With a rapidly changing industry, qualified auto body repair technicians are in short supply, just as they are in the engine repair business. That's also led to upward pressure on pay in the industry as technicians have to be highly qualified and educated, Dillender said. That's good for people who work in the industry, of course, but tougher for those who pay, and for the insurance companies who, in turn, pay for the repairs. A new study from consumer automotive group AAA says the cost to fix sensors and cameras in new vehicles "now accounts for more than a third of the post-crash repair costs," reports CNN. However, "no one, including AAA, recommends not getting these features because of repair costs," since many of them can cut crash rates in half and improve a car's overall safety. "They're not going to prevent everything," said Greg Brannon, director of automotive engineering at AAA. "And when you are in a crash, there are additional costs so it's sort of the old 'there's no free ride' when it comes to these things."

Amazon's Delivery Drones Won't Fly In Arizona's Summer Heat

Par : BeauHD
8 mai 2024 à 00:02
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.
