An anonymous reader quotes a report from The Guardian, written by Caroline Haskins: On May 7th and 8th in Washington, D.C., the city's biggest convention hall welcomed America's military-industrial complex, its top technology companies and its most outspoken justifiers of war crimes. Of course, that's not how they would describe it. It was the inaugural "AI Expo for National Competitiveness," hosted by the Special Competitive Studies Project -- better known as the "techno-economic" thinktank created by the former Google CEO and current billionaire Eric Schmidt. The conference's lead sponsor was Palantir, a software company co-founded by Peter Thiel that's best known for inspiring 2019 protests against its work with Immigration and Customs Enforcement (Ice) at the height of Trump's family separation policy. Currently, Palantir is supplying some of its AI products to the Israel Defense Forces.

The conference hall was also filled with booths representing the U.S. military and dozens of its contractors, ranging from Booz Allen Hamilton to a random company that was described to me as Uber for airplane software. At industry conferences like these, powerful people tend to be more unfiltered – they assume they're in a safe space, among friends and peers. I was curious, what would they say about the AI-powered violence in Gaza, or what they think is the future of war?

Attendees were told the conference highlight would be a series of panels in a large room toward the back of the hall. In reality, that room hosted just one of note. Featuring Schmidt and the Palantir CEO, Alex Karp, the fire-breathing panel would set the tone for the rest of the conference. More specifically, it divided attendees into two groups: those who see war as a matter of money and strategy, and those who see it as a matter of death. The vast majority of people there fell into group one. I've written about relationships between tech companies and the military before, so I shouldn't have been surprised by anything I saw or heard at this conference. But when it ended, and I departed DC for home, it felt like my life force had been completely sucked out of my body. Some of the noteworthy quotes from the panel and convention, as highlighted in Haskins' reporting, include:

"It's always great when the CIA helps you out," Schmidt joked when CIA deputy director David Cohen lent him his microphone when his didn't work.

The U.S. has to "scare our adversaries to death" in war, said Karp. On university graduates protesting Israel's war in Gaza, Karp described their views as a "pagan religion infecting our universities" and "an infection inside of our society."

"The peace activists are war activists," Karp insisted. "We are the peace activists."

A huge aspect of war in a democracy, Karp went on to argue, is leaders successfully selling that war domestically. "If we lose the intellectual debate, you will not be able to deploy any armies in the west ever," Karp said.

A man in nuclear weapons research jokingly referred to himself as "the new Oppenheimer."

In what's marked as an EU first, the French government has blocked TikTok in its territory of New Caledonia amid widespread pro-independence protests. Politico reports: A French draft law, passed Monday, would let citizens vote in local elections after 10 years' residency in New Caledonia, prompting opposition from independence activists worried it will dilute the representation of indigenous people. The violent demonstrations that have ensued in the South Pacific island of 270,000 have killed at least five people and injured hundreds. In response to the protests, the government suspended the popular video-sharing app -- owned by Beijing-based ByteDance and favored by young people -- as part of state-of-emergency measures alongside the deployment of troops and an initial 12-day curfew.

French Prime Minister Gabriel Attal didn't detail the reasons for shutting down the platform. The local telecom regulator began blocking the app earlier on Wednesday. "It is regrettable that an administrative decision to suspend TikTok's service has been taken on the territory of New Caledonia, without any questions or requests to remove content from the New Caledonian authorities or the French government," a TikTok spokesperson said. "Our security teams are monitoring the situation very closely and ensuring that our platform remains safe for our users. We are ready to engage in discussions with the authorities."

Digital rights NGO Quadrature du Net on Friday contested the TikTok suspension with France's top administrative court over a "particularly serious blow to freedom of expression online." A growing number of authoritarian regimes worldwide have resorted to internet shutdowns to stifle dissent. This unexpected -- and drastic -- decision by France's center-right government comes amid a rise in far-right activism in Europe and a regression on media freedom. "France's overreach establishes a dangerous precedent across the globe. It could reinforce the abuse of internet shutdowns, which includes arbitrary blocking of online platforms by governments around the world," said Eliska Pirkova, global freedom of expression lead at Access Now.

An anonymous reader quotes a report from BleepingComputer: The Securities and Exchange Commission (SEC) has adopted amendments to Regulation S-P that require certain financial institutions to disclose data breach incidents to impacted individuals within 30 days of discovery. Regulation S-P was introduced in 2000 and controls how some financial entities must treat nonpublic personal information belonging to consumers. These rules include developing and implementing data protection policies, confidentiality and security assurances, and protecting against anticipated threats.

The new amendments (PDF) adopted earlier this week impact financial firms, such as broker-dealers (funding portals included), investment firms, registered investment advisers, and transfer agents. The modifications were initially proposed in March of last year to modernize and improve the protection of individual financial information from data breaches and exposure to non-affiliated parties. Below is a summary of the introduced changes:

- Notify affected individuals within 30 days if their sensitive information is, or is likely to be, accessed or used without authorization, detailing the incident, breached data, and protective measures taken. Exemption applies if the information isn't expected to cause substantial harm or inconvenience to the exposed individuals.
- Develop, implement, and maintain written policies and procedures for an incident response program to detect, respond to, and recover from unauthorized access or use of customer information. This should include procedures to assess and contain security incidents, enforce policies, and oversee service providers.
- Expand safeguards and disposal rules to cover all nonpublic personal information, including that received from other financial institutions.
- Require documentation of compliance with safeguards and disposal rules, excluding funding portals.
- Align annual privacy notice delivery with the FAST Act, exempting certain conditions.
- Extend safeguards and disposal rules to transfer agents registered with the SEC or other regulatory agencies.

The head of Canada's Security Intelligence Service warned Canadians against using video app TikTok, saying data gleaned from its users "is available to the government of China," CBC News reported on Friday. From a report: "My answer as director of the Canadian Security Intelligence Service (CSIS) is that there is a very clear strategy on the part of the government of China to be able to acquire personal information from anyone around the world," CSIS Director David Vigneault told CBC in an interview set to air on Saturday.

"These assertions are unsupported by evidence, and the fact is that TikTok has never shared Canadian user data with the Chinese government, nor would we if asked," a TikTok spokesperson said in response to a request for comment. Canada in September ordered a national security review of a proposal by TikTok to expand the short-video app's business in the country. Vigneault said he will take part in that review and offer advice, CBC reported.

Michael Larabel reports via Phoronix: Following Germany's Sovereign Tech Fund providing significant funding for GNOME, Rust Coreutils, PHP, a systemd bug bounty, and numerous other free software projects, the FFmpeg multimedia library is the latest beneficiary to this funding from the Germany government. The Sovereign Tech Fund notes that the FFmpeg project is receiving 157,580 euros for 2024 and 2025.

An announcement on the FFmpeg.org project site notes: "The FFmpeg community is excited to announce that Germany's Sovereign Tech Fund has become its first governmental sponsor. Their support will help sustain the [maintenance] of the FFmpeg project, a critical open-source software multimedia component essential to bringing audio and video to billions around the world everyday."

An anonymous reader quotes a report from Ars Technica: It's amazing, and a little sad, to think that something created in 1989 that changed how people used and viewed the then-nascent Internet had nearly vanished by 2024. Nearly, that is, because the dogged researchers and enthusiasts at The Serial Port channel on YouTube have found what is likely the last existing copy of Archie. Archie, first crafted by Alan Emtage while a student at McGill University in Montreal, Quebec, allowed for the searching of various "anonymous" FTP servers around what was then a very small web of universities, researchers, and government and military nodes. It was groundbreaking; it was the first echo of the "anything, anywhere" Internet to come. And when The Serial Port went looking, it very much did not exist.

While Archie would eventually be supplanted by Gopher, web portals, and search engines, it remains a useful way to index FTP sites and certainly should be preserved. The Serial Port did this, and the road to get there is remarkable and intriguing. You are best off watching the video of their rescue, along with its explanatory preamble. But I present here some notable bits of the tale, perhaps to tempt you into digging further.

An anonymous reader quotes a report from Techdirt, written by Mike Masnick: If you're a fan of chaos, well, the TikTok ban situation is providing plenty of chaos to follow. Ever since the US government made it clear it was seriously going to move forward with the obviously unconstitutional and counterproductive plan to force ByteDance to divest from TikTok or have the app effectively banned from the U.S., various rich people have been stepping up with promises to buy the app. There was former Trump Treasury Secretary Steven Mnuchin with plans to buy it. Then there was "mean TV investor, who wants you to forget his sketchy history" Kevin O'Leary with his own TikTok buyout plans. I'm sure there have been other rich dudes as well, though strikingly few stories of actual companies interested in purchasing TikTok.

But now there's another billionaire to add to the pile: billionaire real estate/property mogul Frank McCourt (who has had some scandals in his own history) has had an interesting second act over the last few years as a big believer in decentralized social media. He created and funded Project Liberty, which has become deeply involved in a number of efforts to create infrastructure for decentralized social media, including its own Decentralized Social Networking Protocol (DSTP).

Over the past few years, I've had a few conversations with people involved in Project Liberty and related projects. Their hearts are in the right place in wanting to rethink the internet in a manner that empowers users over big companies, even if I don't always agree with their approach (he also frequently seems to surround himself with all sorts of tech haters, who have somewhat unrealistic visions of the world). Either way, McCourt and Project Liberty have now announced a plan to bid on TikTok. They plan to merge it into his decentralization plans. "Frank McCourt, Founder of Project Liberty and Executive Chairman of McCourt Global, today announced that Project Liberty is organizing a bid to acquire the popular social media platform TikTok in the U.S., with the goal of placing people and data empowerment at the center of the platform's design and purpose," reads a press release from Project Liberty.

"Working in consultation with Guggenheim Securities, the investment banking and capital markets business of Guggenheim Partners, and Kirkland & Ellis, one of the world's largest law firms, as well as world-renowned technologists, academics, community leaders, parents and engaged citizens, this bid for TikTok offers an innovative, alternative vision for the platform's infrastructure -- one that allows people to reclaim agency over their digital identities and data by proposing to migrate the platform to a new digital open-source protocol. In launching the bid, McCourt and his partners are seizing this opportunity to return control and value back into the hands of individuals and provide Americans with a meaningful voice, choice, and stake in the future of the web."

Russia is increasingly seeking to encourage and direct hackers to attack British and other western targets, the director of GCHQ has said in her first keynote speech as head of the British intelligence agency. From a report: Anne Keast-Butler said her agency was "increasingly concerned about growing links" between the Russian intelligence services and proxy hacker groups who have long taken advantage of a permissive environment within the country. "Before, Russia simply created the right environments for these groups to operate but now they're nurturing and inspiring these non state cyber actors," she said in a speech to the Cyber UK conference, in what she described as a "globally pervasive" threat.

The spy chief, appointed last year to be the first woman to hold the role, referenced the threat from ransomware -- "the most acute and pervasive cyber threat" -- where cybercriminals, typically from Russia, take control of a company's data and systems and demand significant sums to regain access. GCHQ was "doing everything we can" to counter ransomware actors, Keast-Butler said, degrade their ability to attack systems across government and business and to "produce intelligence that means those involved in ransomware are held to account." There is "no hiding place" for cybercriminals she added.

With Amazon on its heels, the nation's biggest company by revenue is hunting for ways to continue growing. From a report: For a decade, Walmart has reigned as the nation's biggest company by revenue. Its sales last year added up to $648 billion -- more than $1.2 million a minute. That status comes with benefits. It gives Walmart power in negotiations with product manufacturers and in dealing with government officials over policy issues. It's also a point of pride: Job postings often tout working at the "Fortune 1" company as a perk. Its reign is looking shaky lately [non-paywalled link]. If current sales trends persist, Amazon is likely to overtake Walmart soon. Amazon reported $575 billion in total revenue last year, up 12% from the previous year, compared with Walmart's revenue growth of 6%.

Walmart's behemoth size means that to meet its own sales target of around 4% growth each year, the company has to find an additional $26 billion in sales this year. That's no easy task. About 90% of Americans already shop at the retailer. The pandemic and rising inflation boosted Walmart's revenue by $100 billion since 2019. It faces continued uncertainty in consumer confidence and while it's spending in some areas, it's pulling back in others. Earlier this week, Walmart told workers it would cut hundreds of corporate jobs and ask most remote workers to move to offices. While Amazon's and Walmart's businesses compete head on, there are big differences. Amazon earns much of its profit from non-retail operations such as cloud computing and advertising, while grabbing retail market share with fast shipping. Walmart gets the bulk of its sales and profits from U.S. stores, while growing side businesses like advertising and digital sales.

Walmart executives are most wary of Amazon's ability to keep increasing profits through its non-retail business, while eating more of the retail landscape with ever-faster shipping and a bigger product selection, people familiar with the company said. Internally some executives are highlighting Walmart's role as a good corporate citizen and emphasizing that it's important to be the best at serving customers and workers, not just the biggest, say some of those people. Its scale can also have downsides, say some, like outsize attention on every misstep.

In an op-ed for The Wall Street Journal, Representatives Cathy McMorris Rodgers (R-Wash.) and Frank Pallone Jr (D-N.J.) made their case for why Section 230 of the 1996 Communications Decency Act has "outlived its usefulness." Section 230 of the Communications Decency Act protects online platforms from liability for user-generated content, allowing them to moderate content without being treated as publishers.

"Unfortunately, Section 230 is now poisoning the healthy online ecosystem it once fostered. Big Tech companies are exploiting the law to shield them from any responsibility or accountability as their platforms inflict immense harm on Americans, especially children. Congress's failure to revisit this law is irresponsible and untenable," the lawmakers wrote. The Hill reports: Rodgers and Pallone argued that rolling back the protections on Big Tech companies would hold them accountable for the material posted on their platforms. "These blanket protections have resulted in tech firms operating without transparency or accountability for how they manage their platforms. This means that a social-media company, for example, can't easily be held responsible if it promotes, amplifies or makes money from posts selling drugs, illegal weapons or other illicit content," they wrote.

The lawmakers said they were unveiling legislation (PDF) to sunset Section 230. It would require Big Tech companies to work with Congress for 18 months to "evaluate and enact a new legal framework that will allow for free speech and innovation while also encouraging these companies to be good stewards of their platforms." "Our bill gives Big Tech a choice: Work with Congress to ensure the internet is a safe, healthy place for good, or lose Section 230 protections entirely," the lawmakers wrote.

The United States is heading to Geneva this week to start a series of diplomatic talks with the Chinese government about artificial intelligence safety and risk standards. From a report: The U.S. and China are in tight competition to dominate the AI market, both in the private sector and within their own governments. However, the two world powers have yet to agree on what it means to safely use the technologies they're developing.

The United States and China will meet in Switzerland on Tuesday, senior administration officials told reporters during a briefing Friday. Officials from the White House and State Department will lead the U.S. delegation in the talks, while China will bring a delegation co-led by its Ministry of Foreign Affairs and National Development and Reform Commission. The talks will primarily focus on AI risk and safety "with an emphasis on advanced systems," one official said. Officials from the U.S. and China also plan to discuss the work they're doing in their own countries domestically to address AI risks.

Slashdot reader sonlas shared this report from the BBC: Australia has announced it will ramp up its extraction and use of gas until "2050 and beyond", despite global calls to phase out fossil fuels. Prime Minister Anthony Albanese's government says the move is needed to shore up domestic energy supply while supporting a transition to net zero... Australia — one of the world's largest exporters of liquefied natural gas — has also said the policy is based on "its commitment to being a reliable trading partner". Released on Thursday, the strategy outlines the government's plans to work with industry and state leaders to increase both the production and exploration of the fossil fuel. The government will also continue to support the expansion of the country's existing gas projects, the largest of which are run by Chevron and Woodside Energy Group in Western Australia...

The policy has sparked fierce backlash from environmental groups and critics — who say it puts the interest of powerful fossil fuel companies before people. "Fossil gas is not a transition fuel. It's one of the main contributors to global warming and has been the largest source of increases of CO2 [emissions] over the last decade," Prof Bill Hare, chief executive of Climate Analytics and author of numerous UN climate change reports told the BBC... Successive Australian governments have touted gas as a key "bridging fuel", arguing that turning it off too soon could have "significant adverse impacts" on Australia's economy and energy needs. But Prof Hare and other scientists have warned that building a net zero policy around gas will "contribute to locking in 2.7-3C global warming, which will have catastrophic consequences".

Slashdot reader quonset writes: The last floppy disk was manufactured in 2011. Despite no new supplies being available for over a decade, there are still people, and organizations, who rely on floppy disks. Each has their own story as to why they rely on what is essentially 1970s technology.
From the BBC: Tom Persky, a US businessman, has been selling "new", as in, unopened, floppy disks for years and still finds the trade lucrative. He runs Floppydisk.com, which offers disks for about US$1 (£0.80) each, though some higher capacity versions cost up to US$10 (£8) per disk, he says. Persky has customers all over the world and you could split them roughly 50-50 into hobbyists and enthusiasts like Espen Kraft on one side, and industrial users on the other. This latter category encompasses people who use computers at work that require floppy disks to function. They are, essentially, locked in to a format that the rest of the world has largely forgotten.

"I sell thousands of floppy disks to the airline industry, still," says Persky. He declines to elaborate. "Companies are not happy about when I talk about them." But it is well-known that some Boeing 747s, for example, use floppy disks to load critical software updates into their navigation and avionics computers. While these older aircraft might not be so common in Europe or the US these days, you might find one in the developing world, for instance, Persky hints. There are also pieces of factory equipment, government systems — or even animatronic figures — that still rely on floppy disks.

And in San Francisco, the Muni Metro light railway, which launched in 1980, won't start up each morning unless the staff in charge pick up a floppy disk and slip it into the computer that controls the railway's Automatic Train Control System, or ATCS. "The computer has to be told what it's supposed to do every day," explains a spokesman for the San Francisco Municipal Transport Agency (SFMTA). "Without a hard drive, there is nowhere to install software on a permanent basis."

This computer has to be restarted in such a way repeatedly, he adds — it can't simply be left on, for fear of its memory degrading.
The article also includes this quote from a cybersecurity expert at Pen Test Partners. "If floppy was the only interface, the only way to get malware on to [the computer] would be via said floppy disk. That's quite a limiting factor for the attacker..."

Zitchas writes: The practice of having games require a connection to a publisher's server -- whether it is to check for a license or to access plug-ins and DLC -- is an increasingly common thing in computer software; and many people are concerned that at some point in the future the publisher will shut down their server, and effectively render the person who paid for the game left with something that no longer functions. This has already happened to some games and software

Concerned citizens in Canada are taking the issue to their Parliament in order to push for a law that will mandate that when the server-side support for software is discontinued, companies must leave it in a functional state and remove mandatory connections to servers -- services that no longer exist. Perhaps even more importantly, the petition also asks government to pass a law prohibiting EULA's from forcing users to agree to waiving their right to this. Unfortunately, the petition is only open to citizens of Canada, so the rest of us are out of luck. Considering the potential benefits to the rest of the world if they enact legislation that does this, though, it might be worth suggesting to any of your Canadian friends to go sign the petition.

An anonymous reader quotes a report from The Verge: The Maryland legislature passed two bills over the weekend limiting tech platforms' ability to collect and use consumers' data. Maryland Governor Wes Moore is expected to sign one of those bills, the Maryland Kids Code, on Thursday, MoCo360 reports. If signed into law, the other bill, the Maryland Online Privacy Act, will go into effect in October 2025. The legislation would limit platforms' ability to collect user data and let users opt out of having their data used for targeted advertising and other purposes. Together, the bills would significantly limit social media and other platforms' ability to track their users -- but tech companies, including Amazon, Google, and Meta, have opposed similar legislation. Lawmakers say the goal is to protect children, but tech companies say the bills are a threat to free speech.

Part of the Maryland Kids Code -- the Maryland Age-Appropriate Design Code Act -- will go into effect much sooner, on October 1st. It bans platforms from using "system design features to increase, sustain, or extend the use of the online product," including autoplaying media, rewarding users for spending more time on the platform, and spamming users with notifications. Another part of the legislation prohibits certain video game, social media, and other platforms from tracking users who are younger than 18. "It's meant to rein in some of the worst practices with sensible regulation that allows companies to do what's right and what is wonderful about the internet and tech innovation, while at the same time saying, 'You can't take advantage of our kids,'" Maryland state Delegate Jared Solomon, one of the bill's sponsors, said in a press conference Wednesday.

"We are technically the second state to pass a kids code," Solomon told The New York Times. "But we are hoping to be the first state to withstand the inevitable court challenge that we know is coming."

An anonymous reader quotes a report from TechCrunch: The federal government agency responsible for granting patents and trademarks is alerting thousands of filers whose private addresses were exposed following a second data spill in as many years. The U.S. Patent and Trademark Office (USPTO) said in an email to affected trademark applicants this week that their private domicile address -- which can include their home address -- appeared in public records between August 23, 2023 and April 19, 2024. U.S. trademark law requires that applicants include a private address when filing their paperwork with the agency to prevent fraudulent trademark filings.

USPTO said that while no addresses appeared in regular searches on the agency's website, about 14,000 applicants' private addresses were included in bulk datasets that USPTO publishes online to aid academic and economic research. The agency took blame for the incident, saying the addresses were "inadvertently exposed as we transitioned to a new IT system," according to the email to affected applicants, which TechCrunch obtained. "Importantly, this incident was not the result of malicious activity," the email said. Upon discovery of the security lapse, the agency said it "blocked access to the impacted bulk data set, removed files, implemented a patch to fix the exposure, tested our solution, and re-enabled access." Last June, the USPTO inadvertently exposed about 61,000 applicants' private addresses "in a years-long data spill in part through the release of its bulk datasets," reports TechCrunch. It told affected individuals that the issue was fixed.

Full repairs to three submarine internet cables damaged in the Red Sea in February are being held up by disputes over who controls access to infrastructure in Yemeni waters. From a report: The Yemeni government has granted permits for the repair of two out of three cables, but refused the third because of a dispute with one of the cable's consortium members. Repairs to the Seacom and EIG cables have been approved, but the consortium that runs AAE-1, which includes telecommunications company TeleYemen, was not granted a permit by Yemen's internationally recognized government, according to documents seen by Bloomberg.

Three out of more than a dozen cables that run through the Red Sea, a critical route for connecting Europe's internet infrastructure to Asia's, were knocked offline by the Houthi-sunk Rubymar vessel in late February. Although the telecommunications data that passes along the damaged cables was re-routed, the incident highlighted the vulnerability of critical subsea infrastructure and the challenges of making repairs in a conflict zone. The dispute over the third cable derives from the split political control of TeleYemen, the country's sole telecommunications provider, a reflection of the country's broader geopolitical divisions.

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.
