Led by Associate Professor of Physics Omar S. Magaña-Loaiza, the work establishes a general design principle for engineering an entirely new class of quantum materials, opening new possibilities for quantum computing, secure communications, sensing technologies and advanced energy systems. alternative_right 2026-07-15T16:31:57+00:00 https://slashdot.org/submission/17349002/how-microsofts-little-workaround-created-a-major-pentagon-threat?utm_source=rss1.0&utm_medium=feed ProPublica Reporter Renee Dudley heard Microsoft was running tech support for the U.S. Defense Department through China, the country’s biggest cybersecurity adversary.The arrangement was called “digital escorting.” She thought it sounded like a conspiracy theory — until she started looking into it. This is the story of what she found and how her investigation changed government policy.Microsoft is using engineers in China to help maintain the Defense Department’s computer systems — with minimal supervision by U.S. personnel — leaving some of the nation’s most sensitive data vulnerable to hacking from its leading cyber adversary, a ProPublica investigation has found.The arrangement, which was critical to Microsoft winning the federal government’s cloud computing business a decade ago, relies on U.S. citizens with security clearances to oversee the work and serve as a barrier against espionage and sabotage.National security and cybersecurity experts in the Trump administration contacted by ProPublica were also surprised to learn that such an arrangement was in place, especially at a time when the U.S. intelligence community and leading members of Congress and the Trump administration view China’s digital prowess as a top threat to the country.Microsoft uses the escort system to handle the government’s most sensitive information that falls below “classified.” According to the government, this “high impact level” category includes “data that involves the protection of life and financial ruin.” The “loss of confidentiality, integrity, or availability” of this information “could be expected to have a severe or catastrophic adverse effect” on operations, assets and individuals, the government has said. In the Defense Department, the data is categorized as “Impact Level” 4 and 5 and includes materials that directly support military operations.“If someone ran a script called ‘fix_servers.sh’ but it actually did something malicious then [escorts] would have no idea,” a former Microsoft engineer who worked on the escort system, told ProPublica in an email. That said, he maintained that the “scope of systems they could disrupt” is limited.In an emailed statement, the Defense Information Systems Agency said that cloud service providers “are required to establish and maintain controls for vetting and using qualified specialists,” but the agency did not respond to ProPublica’s questions regarding the digital escorts’ qualifications.It’s unclear whether other cloud providers to the federal government use digital escorts as part of their tech support. Amazon Web Services and Google Cloud declined to comment on the record for this article. Oracle did not respond to requests for comment.A spokesperson for the inspector general — whose office is supposed to operate independently in order to investigate potential waste, fraud and abuse — told ProPublica they were not authorized to speak about the issue and directed questions to DISA public affairs. joshuark 2026-07-14T21:18:31+00:00 https://slashdot.org/submission/17348936/californians-sign-up-to-have-data-brokers-delete-their-personal-information?utm_source=rss1.0&utm_medium=feed More than 300,000 Californians have demanded that hundreds of data brokers erase information about their locations, finances, health and personal lives as the state’s first-in-the-nation Delete Act requires brokers to start the mandatory process of removing data on Aug. 1.Brokers must start accessing deletion requests within 45 days after Aug. 1, then once they have collected those requests, they have another 45 days to report what data they have purged to the agency — known as CalPrivacy — and people who have signed up. ...The information Californians are asking brokers to erase can be extraordinarily sensitive. Of the nearly 600 data brokers in CalPrivacy’s registry, 110 sell people’s precise locations, the registry shows. More than 40 sell identity data that can include Social Security numbers. Almost 70 sell information on people’s gender identity. Seven sell data related to reproductive health, and six sell information on union membership. Eighteen sell minors’ data — and Kemp said children can sign up for deletion using DROP, or parents can do it for them.Many of the brokers build — and sell to advertisers and marketers — dossiers that are increasingly processed using artificial intelligence to draw conclusions about a person’s interests, family, politics, lifestyle, finances, sexual orientation and health.

The company says the curves could help cloud providers, data centers, AI labs, and other heavy compute users plan spending and manage the risk of future price changes.The curves are not tradable assets, but they can serve as reference prices for private agreements, swaps, and block trades. Kalshi claims compute could eventually become a commodity market larger than oil futures, although that will depend on whether its GPU markets attract enough liquidity to produce reliable pricing.

But with fixes for 622 unique CVEs, Microsoft’s July 2026 Patch Tuesday update is the largest by far in the program's history and offers a preview of the growing prioritization challenges organizations face as AI dramatically increases the volume of flaws requiring attention. July's update contains fixes for three zero-day vulnerabilities, two of which attackers are already exploiting and one that's publicly known but remains unexploited. The patch update also includes fixes for more than five dozen critical vulnerabilities, many of which Microsoft identified as flaws that attackers are more likely to exploit. The total includes 416 vulnerabilities in Windows, 82 each in Office and Office 2016, 46 in Edge, 27 in Microsoft Developer Tools, and 17 in SharePoint Server. "If people want a severity hook, July has 26 vulnerabilities with a CVSS base score above 9.0, and 13 of those sit at 9.8," said Josh Taylor, lead cybersecurity analyst at Fortra, in an emailed comment. "That matters, but CVSS is still only one part of the risk story. The real triage problem this month is the mix of exploited issues, a publicly disclosed BitLocker flaw, and a massive concentration of vulnerabilities in Windows and Office," he said. And rather than focusing on volume, patching teams need to prioritize the exploited vulnerabilities and their exposed infrastructure first, Taylor added. "Today, July 14, 2026, marks a pivotal moment in our industry," researchers from Nightwing said in a statement. "We are officially moving past the traditional 'Patch Tuesday' approach and entering an era of continuous, high-volume security updates" and continuous patching. schwit1 2026-07-15T00:56:05+00:00 https://slashdot.org/submission/17348912/stormwall-scientists-propose-space-based-shield-against-dangerous-solar-storms?utm_source=rss1.0&utm_medium=feed Walsh and his colleagues explored a different approach: modifying near-Earth space to reduce the impact of incoming solar storms. The idea draws inspiration from a natural process in which particles from Earth’s upper atmosphere drift outward and help reinforce parts of the planet’s magnetosphere. This magnetic bubble shields Earth from charged particles.Under the proposed StormWall architecture, six spacecraft would operate in geosynchronous orbit. Each vehicle would carry stores of material such as barium or lithium. When a major solar storm is forecast, the spacecraft would release this material into space. Sunlight would ionise the particles, creating a cloud of plasma that spreads toward the outer regions of Earth’s magnetosphere.According to the team’s computer simulations, the added plasma could alter how solar storm energy enters the magnetosphere. In some scenarios, it reduced the intensity of a major geomagnetic storm by roughly 50% and redirected a significant fraction of the incoming energy away from Earth. fjo3 2026-07-11T01:30:03+00:00 https://slashdot.org/submission/17349058/ai-executives-add-personal-security-as-backlash-turns-violent?utm_source=rss1.0&utm_medium=feed In April, someone threw a Molotov cocktail at Sam Altman's San Francisco home, and within days a second attack put gunfire into the property. The Wall Street Journal reports that AI executives are hardening personal security as opposition to the industry moves from online posts into the physical world.Prosecutors say Daniel Moreno-Gama, the 20-year-old accused in the first attack, traveled from Texas to San Francisco intending to kill Altman, and had writings on him about AI's purported risk to humanity. He faces two counts of attempted murder and attempted arson in California state court. Two more suspects were later arrested in connection with the second incident. Around the same time, The Information described Silicon Valley leaning into a new breed of bodyguards for AI leadership.The pressure isn't only on the people at the top. According to the Data Center Watch Q1 2026 report, organized opposition groups roughly doubled from 396 at the end of last year to 833 by the end of March, spanning 49 states, and opponents blocked or delayed at least 75 projects worth about $130 billion in a single quarter.

Doubao informed users in a Friday night notice that its agent feature would go offline on July 15 because of “product function adjustments”. After October 15, Doubao’s related data would be handled in accordance with the company’s privacy policy and no longer be viewable or recoverable inside the app. Qwen also issued a similar notice on Saturday morning, saying that its “humanlike interactive agents and user-created agent functions” would be disabled on July 10, while broader “Qwen agent functions and services” would be taken offline on July 15. Users would no longer be able to access related agent settings or previous conversations after the shutdown. Both apps had offered a pool of agents, created by both the companies and users, that could be customised for specific tasks, skills and speaking styles. Users could also create their own agents, turning a general-purpose chatbot into a named assistant, tutor, role-playing character or companion with a fixed persona and tone. The timing coincides with the implementation of the Interim Measures for the Administration of Artificial Intelligence Anthropomorphic Interaction Services, effective July 15. Issued in April, the rules cover AI services that “simulate human personality traits, thinking patterns and communication styles to provide sustained emotional interaction”. The rules exclude customer service bots, knowledge Q&A, workplace assistants, education and scientific research tools, as long as they do not involve sustained emotional interaction. schwit1 2026-07-15T21:08:30+00:00 https://slashdot.org/submission/17349054/ai-data-centers-being-built-faster-than-they-can-be-secured?utm_source=rss1.0&utm_medium=feed AI is reshaping data centers and introducing security risks traditional architectures weren't designed to handle.

The most cutthroat banks and consulting firms brag about hiring rates of 1%. Citadel and Citadel Securities took 0.36% of the quants who applied for internships this summer. NASA lets in 0.1% of those who want to be astronauts. But 0.04%? It means that getting a job at Bending Spoons is 100 times harder than getting into Harvard.The company is run by executives in their 30s and early 40s. The employees are mostly in their 20s and 30s and have never worked anywhere else. Many are younger than the brands they take over.“Being able to spot people who are unusually talented and motivated very early in their careers, then giving them unusually high levels of responsibility and coaching, has been an absolutely key advantage for us,” said Ferrari, who is 41.It’s a key part of the business model, too. When Bending Spoons buys a company, it begins each radical transformation by slashing most of the acquired employees—and replacing them with the much leaner team of Spooners.There are now about 700 people who made it through the notorious hiring process and now work in technical, product and growth roles across the organization. They move from one Bending Spoons acquisition to the next, making what Ferrari calls “very deep changes”—rewriting the code, rebuilding the infrastructure, redesigning the user interface. And they are “held to particularly demanding performance standards,” the company promises.In fact, an entire team of Spooners does nothing but evaluate other Spooners and potential Spooners. schwit1 2026-07-11T19:01:08+00:00 https://slashdot.org/submission/17348916/cloudflare-netlify-and-vercel-with-new-toys-for-phishers-and-threat-actors?utm_source=rss1.0&utm_medium=feed Web Bros’ Latest Genius Move: Drop a Zip, Ship Malware Cloudflare, Vercel, and Netlify have all launched their own “Drop” services: upload a zip, get a live site instantly on their edge networks.

I dug into several outages, the extreme weather behind them, and what we can do to help keep the lights on. [...] The claim that hundreds of thousands of Americans were without power over extended periods at least once per month, every month of 2026 surprised be in two ways. First, because I had no idea if it was true – and, second, because it felt true. We try to do better than writing about things that feel true around here, however, so I did a bit of research (translation: I Googled power outages by month) and came up with the following examples in about sixty seconds January: More than 296,000 customers still without power as winter storm freezes much of the US February: More than 380,000 customers without power as winter storm hits US Northeast March: Storms Cut Power to Over 1 Million Customers in US Midwest, Mid-Atlantic; Ohio Hardest Hit April: At least 29 tornadoes touched down in Central Illinois on April 17th May: Energy Secretary Issues Emergency Order to Deploy Backup Generation in the Mid-Atlantic Amid Heatwave June: More than 373,000 US customers without power due to extreme weather ... and that list is far from comprehensive, and how you feel about it might depend on what you consider a “major” outage, of course – but consider that there are tens of thousands of Americans without power right now, and that’s not making the news. [...] The lesson here is that weather-related grid outages – whether they’re caused by wildfires, mudslides, derechos, tornadoes, ice storms, hurricanes, heat waves, or some other disaster I’m lucky enough to have forgotten about – read like statistics when they’re happening over there, but get personal real quick when they’re happening to you.

The settlement between Google and Epic that aimed to put to rest the companies’ long-running antitrust battle is being withdrawn, and that means third-party app stores are coming to the Play Store. Google has confirmed that it will begin distributing rival app stores next week, setting the stage for competing platforms to take a bite out of Google’s Android revenue stream. [...] Google and Epic were set to return to court on July 16 to argue in favor of the settlement. However, the writing may have been on the wall. In a recent expert analysis provided to the court, MIT economics professor Nancy Rose noted that the settlement was “unlikely to enable Google Play’s potential competitors to overcome their long-standing network-effect disadvantage in a timely manner.” With settlement approval looking increasingly unlikely, Epic and Google agreed this week to call the whole thing off. Here’s how Google Trust and Reputation Communications Lead Dan Jackson explains the company’s decision: “We’ve agreed with Epic to withdraw our motion to modify the US Court’s injunction rather than prolonging this process which creates uncertainty for the ecosystem. This allows us to focus on executing our recently announced global business model evolution to deliver greater app store choice, lower prices, and more opportunities for developers and users. We remain committed to maintaining Android’s industry-leading security and fostering a competitive ecosystem where every app store and developer has the freedom to compete. In parallel, we continue to comply with the US Court’s injunction.” In a brief filing (PDF), Google’s legal team informs the court that Google is prepared to begin distributing third-party app stores in Google Play on July 22. Under the terms of Judge Donato’s original injunction, these stores will have access to the full catalog of Google Play apps by default. Developers will have the option to opt out of distribution in these stores, and Google has a support page explaining how to do so. Google also has documentation on how app stores can get access to the Google Play catalog. It won’t be mirroring those apps in any shady storefront that asks. The court has allowed Google to charge reasonable fees to cover its security and compliance review of third-party stores, which will be $5,000 per year. Google will also require approved stores to block malware, respect intellectual property, and include mechanisms to update and uninstall apps. App stores can be removed from the program if more than 1 percent of attempted app installs appear to be malware or unwanted software. It’s unclear if there will be separate, possibly more stringent requirements for storefront distribution in the Play Store. However, Google is prohibited from unreasonably blocking third-party store clients uploaded to Google Play. The changes Google has announced under the Epic agreement will proceed for now. That means Registered App Stores will happen globally, but they will probably only appear in the Play Store for US users. Google hasn’t specified if there will be any differences in the features available to the stores downloaded from Play versus registered stores.

The basic idea is so simple, even a freshman physics student could describe it: use an electric motor to raise a weight up against gravity, and then when you need energy, lower the weight back down, and use the energy to run a generator. The difficulty, however, is in scale. Their proof of concept unit, a 40-ton block of steel falling the height of a 30-story building, stores an amount of energy equal to about eight hours of an average American home’s electricity. Their solution was to go big: there are literally millions of abandoned mine shafts around the world, many of them kilometer and more deep. They proposed a full GraviStore system would hang up to 24 separate weights of 500 metric tons each from cabled winches inside a single shaft. Twelve thousand metric tons of suspended steel, going up and down forever. But turning their concept into a reality ended up spending money faster than it could be invested, and, so quietly it took investors three months to even notice, the company went bankrupt.But the basic concept may not be dead. Several other companies are still working at turning the concept into reality. And hundreds of thousands of abandoned mines are scattered across the United States, most of them a liability, a few of them with a kilometer of free vertical drop and a hoist house and a grid connection already sitting on site.

The innovation constructs a coplanar drain-channel-source unified structure called Guiyi, enabling clear observation of single-electron charge storage behavior at 27 degrees Celsius for the first time. The breakthrough builds on the team previous Nature publication from April 2025, where they demonstrated the PoX flash device achieving 400-picosecond non-volatile storage, the fastest semiconductor charge storage technology ever reported. Quantum Flash addresses the fundamental storage density limit by achieving one electron per bit, the smallest physically possible data unit as electrons are indivisible elementary particles. Traditional memory hierarchy separates high-speed cache from slow bulk storage. Quantum Flash technology, combined with the team PoX speed breakthrough and Changying prototype chip that has already demonstrated CMOS-compatible integration, points toward unified memory that is simultaneously fast, dense, and non-volatile. This would fundamentally change AI chip architecture by eliminating the data migration bottleneck between compute and storage. If commercialization, planned within 1 to 3 years, is successful, the technology could enable mobile devices and servers to run larger (e.g. the 2.8T-parameter Kimi K3 unveiled on the same day) local AI models with longer context memory while consuming significantly less power. hackingbear 2026-07-17T21:36:05+00:00
