Live Science spoke with physicist David Gross, who today received the $3 million "Special Breakthrough Prize in Fundamental Physics". He was part of a trio that won the 2004 physics Nobel prize for research that helped complete the Standard Model of particle physics. But when asked if physics will reach a unified theory of the fundamental forces of nature within 50 years, Gross has a surprising answer. "Currently, I spend part of my time trying to tell people... that the chances of you living 50 [more] years are very small."

Cold War estimates for a 1% chance of nuclear war each year seem low, Gross says. "The chances are more likely 2%. So that's a 1-in-50 chance every year." David Gross: The expected lifetime, in the case of 2% [per year], is about 35 years. [The expected lifetime is the average time it would take to have had a nuclear war by then. It is calculated using similar equations as those used to determine the "half-life" of a radioactive material.]

Live Science: So what do you suggest as remedies to lower that risk?

Gross: We had something called the Nobel Laureate Assembly for reducing the risk of nuclear war in Chicago last year. There are steps, which are easy to take — for nations, I mean. For example, talk to each other. In the last 10 years, there are no treaties anymore. We're entering an incredible arms race.

We have three super nuclear powers. People are talking about using nuclear weapons; there's a major war going on in the middle of Europe; we're bombing Iran; India and Pakistan almost went to war. OK, so that's increased the chance [of nuclear war]. I would really like to have a solid estimate — it might be more, and I think I'm being conservative — but a 2% estimate [of nuclear war] in today's crazy world.

Live Science: Do you think we'll ever get to a place where we get rid of nuclear weapons?

Gross: We're not recommending that. That's idealistic, but yes, I hope so. Because if you don't, there's always some risk an AI 100 years from now [could launch nuclear weapons], but chances of [humanity] living, with this estimate, 100 years, is very small, and living 200 years is infinitesimal. So [the answer to] Fermi's question of "Where are the civilizations, all the intelligent organisms around the galaxy, and why don't they talk to us?" is that they've killed themselves...

There are now nine nuclear powers. Even three is infinitely more complicated than two. The agreements, the norms between countries, are all falling apart. Weapons are getting crazier. Automation, and perhaps even AI, will be in control of those instruments pretty soon... It's going to be very hard to resist making AI make decisions because it acts so fast.
He points out that with the threat of climate change, "people have done something," even though "It's a much harder argument to make than about nuclear weapons.

"We made them; we can stop them."

In October and through November, America's EV sales reached their lowest point since 2022 after government subsidies expired, remembers Time. "But first-quarter data for 2026 shows that used EV sales were 12% higher than the same time last year and 17% higher than the previous quarter.

"One factor likely helping push buyers toward these cars is high gas prices, which recently topped $4.00 a gallon for the first time in four years," they write — but it's not just in the U.S. Instead, they argue the U.S.-Iran conflict "is driving a global surge of interest in electric vehicles..." In the U.K., electric car sales reached a record high, with 86,120 vehicles sold in March... The French online used-car retailer Aramisauto reported its share of EV sales nearly doubled from February 16 to March 9, rising to 12.7% from 6.5%, while sales of fueled models dropped to 28% of sales from 34%, and sales of diesel models dropped to 10% from 14%. Germany's largest online car market, mobile.de, told Reuters that the share of EV searches on its website has tripled since the start of March — from 12% to 36%, with car dealers receiving 66% more enquiries for used EVs than in February.

South Korea reported that registrations for electric vehicles more than doubled in March compared to the prior year, due in part to rising fuel prices and government subsidies... In New Zealand, more than 1,000 EVs were registered in the week that ended on March 22, close to double the week before, making it the country's biggest week for electric vehicle registrations since the end of 2023, according to the country's Transport Minister, Chris Bishop.
In America, Bloomberg also reports 605 high-speed EV charging stations switched on in just the first three months of 2025, "a 34% increase over the year-earlier period," according to their analysis of federal data. A data platform focused on EV infrastructure tells Bloomberg that speedier and more reliable chargers are convincing more drivers to go electric and use public plugs.

"Motorola has filed a lawsuit in India against social media platforms and content creators," reports TechCrunch, "over posts it alleges are defamatory..." The lawsuit, filed in a Bengaluru court and obtained by TechCrunch, names platforms such as X, YouTube, and Instagram along with dozens of content creators, and seeks takedown of the content as well as broader restraint on what it describes as false or defamatory material related to the company's devices. In its over 60-page filing, Motorola has sought a permanent injunction restraining the defendants from publishing or sharing what it describes as false or defamatory content about its products, including reviews, videos, comments, and boycott campaigns.

The complaint cites hundreds of posts across platforms, including videos alleging device issues and phones catching fire. But it is also targeting unfavorable product reviews and user commentary that the company alleges are false or defamatory. In a statement after publication, a Motorola spokesperson said it had initiated legal action "in the interest of public safety" against what it described as demonstrably false claims that its devices had exploded or caught fire.
One online creator told TechCrunch "they expect more such legal action in the future, as evolving rules around online content increase liability for creators and platforms — a trend reflected in recently proposed changes to India's IT rules aimed at tightening oversight of online content."

A Motorola spokesperson "said the company did not seek to suppress legitimate reviews or criticism and was reviewing the scope of the proceedings, adding that it apologized to creators affected inadvertently."

Slashdot reader Bismillah shared this report from ITNews: Research and development engineer Romain Marchand of Paris headquartered Quarkslab obtained a telematic control unit (TCU) from a salvage yard in Poland... Marchand tore down the TCU, which is based on a Qualcomm system on a chip, and extracted the Linux-based file system from the Micron multi-chip package (MCP) which contained NAND-based non-volatile storage memory. The non-volatile storage contained sensitive information, including system configuration data and more importantly, logs that revealed the vehicle's GPS positions over time.

None of that information was encrypted, Marchand told iTnews, which made it possible to collect and retrieve sensitive data of interest. What's more, the global navigation satellite system (GNSS) logs with GPS positions covered the BYD's full journey from the factory in China to its operational life in the United Kingdom, and to its final wrecking in Poland, Marchand explained in an analysis... The issue is not restricted to BYD, and Marchand added that the hardware architecture of the Chinese car maker's TCU is broadly similar to what can be found in other brands.

BrianFagioli writes: Mozilla's email subsidiary MZLA Technologies just introduced Thunderbolt, an open-source AI client aimed at organizations that want to run AI on their own infrastructure instead of relying entirely on cloud services. The idea is to give companies full control over their data, models, and workflows while still offering things like chat, research tools, automation, and integration with enterprise systems through the Haystack AI framework. Native apps are planned for Windows, macOS, Linux, iOS, and Android. Thunderbolt allows organizations to do the following:
- Run AI with their choice of models, from leading commercial providers to open-source and local models
- Connect to systems and data: Integrate with pipelines and open protocols, including: deepset's Haystack platform, Model Context Protocol (MCP) servers, and agents with the Agent Client Protocol (ACP)
- Automate workflows and recurring tasks: Generate daily briefings, monitor topics, compile reports, or trigger actions based on events and schedules
- Work seamlessly across devices with native applications for Windows, macOS, Linux, iOS, and Android
- Maintain security with self-hosted deployment, optional end-to-end encryption, and device-level access controls

Longtime Slashdot reader AmiMoJo writes: Windows has limited FAT32 partitions to a maximum of 32GB for decades now. When memory cards and USB drives exceeded 32GB in size, the only options were exFAT or NTFS. Neither option was well supported on other platforms at first, although exFAT support is fairly widespread now. In their latest blog post, Microsoft announced that the limit for FAT32 partitions is being increased to 2TB. Of course, that doesn't mean that every device that supports FAT32 will work flawlessly with a 2TB partition size, but at least there is a decent chance that older devices with don't support exFAT will now be usable with memory cards over 32GB.

An anonymous reader quotes a report from Ars Technica: Two years ago, Microsoft launched its first wave of "Copilot+" Windows PCs with a handful of exclusive features that could take advantage of the neural processing unit (NPU) hardware being built into newer laptop processors. These NPUs could enable AI and machine learning features that could run locally rather than in someone's cloud, theoretically enhancing security and privacy. One of the first Copilot+ features was Recall, a feature that promised to track all your PC usage via screenshot to help you remember your past activity. But as originally implemented, Recall was neither private nor secure; the feature stored its screenshots plus a giant database of all user activity in totally unencrypted files on the user's disk, making it trivial for anyone with remote or local access to grab days, weeks, or even months of sensitive data, depending on the age of the user's Recall database.

After journalists and security researchers discovered and detailed these flaws, Microsoft delayed the Recall rollout by almost a year and substantially overhauled its security. All locally stored data would now be encrypted and viewable only with Windows Hello authentication; the feature now did a better job detecting and excluding sensitive information, including financial information, from its database; and Recall would be turned off by default, rather than enabled on every PC that supported it. The reconstituted Recall was a big improvement, but having a feature that records the vast majority of your PC usage is still a security and privacy risk. Security researcher Alexander Hagenah was the author of the original "TotalRecall" tool that made it trivially simple to grab the Recall information on any Windows PC, and an updated "TotalRecall Reloaded" version exposes what Hagenah believes are additional vulnerabilities.

The problem, as detailed by Hagenah on the TotalRecall GitHub page, isn't with the security around the Recall database, which he calls "rock solid." The problem is that, once the user has authenticated, the system passes Recall data to another system process called AIXHost.exe, and that process doesn't benefit from the same security protections as the rest of Recall. "The vault is solid," Hagenah writes. "The delivery truck is not." The TotalRecall Reloaded tool uses an executable file to inject a DLL file into AIXHost.exe, something that can be done without administrator privileges. It then waits in the background for the user to open Recall and authenticate using Windows Hello. Once this is done, the tool can intercept screenshots, OCR'd text, and other metadata that Recall sends to the AIXHost.exe process, which can continue even after the user closes their Recall session.

"The VBS enclave won't decrypt anything without Windows Hello," Hagenah writes. "The tool doesn't bypass that. It makes the user do it, silently rides along when the user does it, or waits for the user to do it." A handful of tasks, including grabbing the most recent Recall screenshot, capturing select metadata about the Recall database, and deleting the user's entire Recall database, can be done with no Windows Hello authentication. Once authenticated, Hagenah says the TotalRecall Reloaded tool can access both new information recorded to the Recall database as well as data Recall has previously recorded. "We appreciate Alexander Hagenah for identifying and responsibly reporting this issue. After careful investigation, we determined that the access patterns demonstrated are consistent with intended protections and existing controls, and do not represent a bypass of a security boundary or unauthorized access to data," a Microsoft spokesperson told Ars. "The authorization period has a timeout and anti-hammering protection that limit the impact of malicious queries."

BrianFagioli writes: The developers behind Linux Mint say the project is rethinking its release strategy and moving toward a longer development cycle, with the next version now expected around Christmas 2026. In a monthly update, project lead Clement Lefebvre said the team reached a "crossroads" and needs more flexibility to fix bugs, improve the desktop, and adapt to rapid changes across the Linux ecosystem. The upcoming development build, temporarily called Mint 23 "Alfa," is currently based on Ubuntu 26.04 LTS and includes Linux kernel 7.0, an unstable build of Cinnamon 6.7, and early Wayland related work.

Mint is also replacing the long used Ubiquity installer with "live-installer," the same tool used by Linux Mint Debian Edition, allowing the project to unify installation infrastructure across its Ubuntu based and Debian based variants. While the team frames the changes as an opportunity to improve quality and reduce maintenance overhead, the shift has raised questions about the project's long term direction and whether Linux Mint may eventually lean more heavily on its Debian roots rather than its traditional Ubuntu base.

An anonymous reader quotes a report from Reuters: Alphabet's Google is negotiating an agreement with the Department of Defense that would allow the Pentagon to deploy its Gemini AI models in classified settings, the Information reported on Thursday, citing two people with direct knowledge of the discussions. The two parties are discussing an agreement that would allow the Pentagon to use Google's AI for all lawful uses, according to the report.

During the negotiations, Google has proposed additional language in its contract with the department to prevent its AI from being used for domestic mass surveillance or autonomous weapons without appropriate human control, the Information reported. The Pentagon will continue to deploy frontier AI capabilities through strong industry partnerships across all classification levels, a Pentagon official said, without confirming any talks with Google.

IPv6 usage briefly reached 50% across Google services for the first time, marking a major milestone for a protocol created in 1998 to solve IPv4's address shortage. Tom's Hardware reports: [...] IPv6 was dismissed early on as a headache-inducing, hard-to-implement complication that would hardly ever gain any traction -- despite offering 2^128 possible numbers, solving all network number assignments in one fell swoop. That changed over time by force of necessity, and Google's tracking graph shows that for a brief moment in time on March 28, 50% of worldwide users accessed the service over an IPv6 connection, marking a historic first. APNIC's stats show that the protocol is in use by 43% of the world, with Asia and the Americas inching ever close to those 50%. Cloudflare, meanwhile, shows that 40% of traffic is done in IPv6, an actually impressive figure if you consider it's measuring actual transferred packets rather than just counting addresses.

The tried-and-true IPv4 and its well-known 123.456.789.123 format from 1980 offers ~4.3 billion addresses in theory, and around 3.7 billion in practice. That always sounded like a lot, but nobody could have predicted just how rapid the explosion of the Internet would be. IANA, the entity controlling the North-American IPv4 space, ran out of IPv4 addresses around 2011, while its European equivalent RIPE NCC could spare no more four-octet addresses nearly seven years ago in 2019. Asian, African, and Latin-American IP registries equally ran out during that timeframe.

An anonymous reader quotes a report from UploadVR: A group of independent researchers built a device that can artificially induce smell using ultrasound, with no consumable cartridges required. [...] The team of four are Lev Chizhov, Albert Yan-Huang, Thomas Ribeiro, Aayush Gupta. Chizhov is a neurotech entrepreneur with a background in math and physics, Yan-Huang is a researcher at Caltech with a background in computation and neural systems, and Ribeiro and Gupta are co-researchers on the project with software engineering and AI expertise.

Instead of targeting your nose at all, the device directly targets the olfactory bulb in your brain with "focused ultrasound through the skull." The researchers say that as far as they're aware, no one has ever done this before, even in animals. A challenge in targeting the olfactory bulb is that it's buried behind the top of your nose, and your nose doesn't provide a flat surface for an emitter. Ultrasound also doesn't travel well through air. The solution the researchers came up with was to place the emitter on your forehead instead, with a "solid, jello-like pad for stability and general comfort," and the ultrasound directed downward towards the olfactory bulb.

To determine the best placement, they say they used an MRI of one of their skulls to "roughly determine where the transducer would point and how the focal region (where ultrasound waves actually concentrate) aligned with the olfactory bulb (the target for stimulation)". [...] According to the researchers, they were able to induce the sensation of fresh air "with a lot of oxygen", the smell of garbage "like few-day-old fruit peels," an ozone-like sensation "like you're next to an air ionizer," and a campfire smell of burning wood. While technically head-mounted, the current device does require being held up with two hands. But as with all such prototypes, it likely could be significantly miniaturized.

Some Japanese bullet trains will soon support premium private suites this October, featuring windows with embedded 5G antennas for steadier onboard Wi-Fi and NTT noise-cancelling cabin tech to reduce train noise. The 5G window antennas are designed to maintain line-of-sight connections as trains race past base stations at up to 285 km/h. The Register reports: Rail operator JR Central announced the new tech late last month and will initially deploy a couple of the suites on six trains. The carrier explained that the antennas come from a Japanese company called AGC that weaves microscopic wires through glass to form an antenna. JR Central will connect the windows to an on-train Wi-Fi router.

AGC says rival tech relies on 5G signals reaching a train and then bouncing around inside before reaching the Wi-Fi unit. The company says antennas woven into train windows maintain line of sight to nearby 5G base stations. That matters because JR Central's Shinkansen can achieve speeds of up to 285 km/h, which means they speed past cellular network base stations so quickly that it's frequently necessary to reconnect to another radio. AGC says keeping a line of sight connection means its antennas allow increased 5G signal strength, so Wi-Fi service on board trains should be more stable and speedy.

The sound-deadening kit JR Central will deploy is called Personalized Sound Zone (PSZ) and comes from Japan's tech giant NTT. The tech uses the same principles applied to noise-cancelling headphones -- determine the waveform of sound and project an inversion of that waveform that cancels out ambient noise.

In an interview with Fox News, Ford CEO Jim Farley warned that allowing Chinese vehicle imports could put nearly a million U.S. jobs at risk. He said China's heavily subsidized auto industry has enough excess capacity to supply the entire U.S. market, while also raising serious cybersecurity concerns given how much data modern connected cars collect. Ars Technica reports: "First of all, the Chinese have huge direct support for their auto companies," Farley said, while noting that China has the ability to build an additional 21 million vehicles a year on top of the 29 million that are expected to roll off Chinese production lines in 2026. "They have enough capacity in China to cover all the manufacturing, all the vehicle sales in the United States," Farley said.

"Manufacturing is the heart and soul of our country, and for us to lose those exports would be devastating for our country," he continued, before pointing out the cybersecurity worries about Chinese cars. "All the vehicles have 10 cameras. They can collect a lot of data," he said.

Farley has praised Chinese EVs like the Xiaomi SU7, even going on podcasts to sing its praises. But he believes Ford's forthcoming affordable Kentucky-built EVs, due to start hitting dealerships next year, have what it takes to be competitive. When asked about new car prices rising an average of 2 percent last year, Farley repeatedly said that Ford had "worked with the administration" so that there's "essentially no big impact" of the Trump tariffs. The CEO justified the rising costs by pointing to the F-150's sales as proof of its value.

Cal is moving its flagship scheduling software from open source to a proprietary license, arguing that AI coding tools now make it much easier for attackers to scan public codebases for vulnerabilities. "Open source security always relied on people to find and fix any problems," said Peer Richelsen, co-founder of Cal. "Now AI attackers are flaunting that transparency." CEO Bailey Pumfleet added: "Open-source code is basically like handing out the blueprint to a bank vault. And now there are 100x more hackers studying the blueprint." The company says it still supports open source and is releasing a separate Cal.diy version for hobbyists, but doesn't want to risk customer booking data in its commercial product. ZDNet reports: When Cal was founded in 2022, Bailey Pumfleet, the CEO and co-founder, wrote, "Cal.com would be an open-source project [because] limitations of existing scheduling products could only be solved by open source." Since Cal was successful and now claims to be the largest Next.js project, he was on to something. Today, however, Pumfleet tells me that AI programs such as "Claude Opus can scour the code to find vulnerabilities," so the company is moving the project from the GNU Affero General Public License (AGPL) to a proprietary license to defend the program's security.

[...] Cal also quoted Huzaifa Ahmad, CEO of Hex Security, "Open-source applications are 5-10x easier to exploit than closed-source ones. The result, where Cal sits, is a fundamental shift in the software economy. Companies with open code will be forced to risk customer data or close public access to their code." "We are committed to protecting sensitive data," Pumfleet said. "We want to be a scheduling company, not a cybersecurity company." He added, "Cal.com handles sensitive booking data for our users. We won't risk that for our love of open source."

While its commercial program is no longer open source, Cal has released Cal.diy. This is a fully open-source version of its platform for hobbyists. The open project will enable experimentation outside the closed application that handles high-stakes data. Pumfleet concluded, "This decision is entirely around the vulnerability that open source introduces. We still firmly love open source, and if the situation were to change, we'd open source again. It's just that right now, we can't risk the customer data."

Amazon is buying satellite communications company Globalstar for $10.8 billion to expand its Leo satellite-internet network and compete more directly with SpaceX's Starlink. The deal also includes a partnership with Apple to support satellite connectivity for iPhones and Apple Watches, with Amazon planning voice, data, and messaging services starting in 2028. The New York Times reports: Leo was Amazon's move to enter the market for beaming high-speed internet to the ground from orbit. That is an arena dominated by Elon Musk's SpaceX, which operates the Starlink satellite-internet service. Starlink, which has thousands of satellites in orbit, already serves several million customers around the world. This month, SpaceX filed to go public in what is shaping up to be one of the largest-ever initial public offerings. Mr. Musk has valued SpaceX -- which has landed contracts with federal agencies such as NASA and the Department of Defense -- at more than $1 trillion. Other companies are racing to catch up to what Mr. Musk has built for space.

Globalstar, founded in 1991, is a Louisiana-based global telecommunications company. It operates networks of low-Earth orbiting satellites to provide internet connectivity to customers. Paul Jacobs, Globalstar's chief executive, said in a statement that together, the two companies "will advance innovations in digital connectivity."

alternative_right shares a report from 404 Media: An independent privacy audit of Microsoft, Meta, and Google web traffic in California found that the companies may be violating state regulations and racking up billions in fines. According to the audit from privacy search engine webXray, 55 percent of the sites it checked set ad cookies in a user's browser even if they opted out of tracking. Each company disputed or took issue with the research, with Google saying it was based on a "fundamental misunderstanding" of how its product works.

The webXray California Privacy Audit viewed web traffic on more than 7,000 popular websites in California in the month of March and found that most tech companies ignore when a user asks to opt-out of cookie tracking. California has stringent and well defined privacy legislation thanks to its California Consumer Privacy Act (CCPA) which allows users to, among other things, opt out of the sale of their personal information. There's a system called Global Privacy Control (GPC), which includes a browser extension that indicates to a website when a user wants to opt out of tracking.

According to the webXray audit, Google failed to let users opt out 87 percent of the time. "Google's failure to honor the GPC opt-out signal is easy to find in network traffic. When a browser using GPC connects to Google's servers it encodes the opt-out signal by sending the code 'sec-gpc: 1.' This means Google should not return cookies," the audit said. "However, when Google's server responds to the network request with the opt-out it explicitly responds with a command to create an advertising cookie named IDE using the 'set-cookie' command. This non-compliance is easy to spot, hiding in plain sight."

The audit said that Microsoft fails to opt out users in the same way and has a failure rate of 50 percent in the web traffic webXray viewed. Meta's failure rate was 69 percent and a bit more comprehensive. "Meta instructs publishers to install the following tracking code on their websites. The code contains no check for globally standard opt-out signals -- it loads unconditionally, fires a tracking event, and sets a cookie regardless of the consumer's privacy preferences," the audit said. It showed a copy of Meta's tracking data which contains no GPC check at all.

UK Prime Minister Keir Starmer said social media platforms should remove addictive infinite-scroll features for young users as Britain considers new child-safety measures. "We're consulting on whether there should be a ban for under 16s," Starmer told BBC Radio. "But I think equally important, the addictive scrolling mechanisms are really problematic to my mind. They need to go." Reuters reports: Britain, like other countries, is considering restricting access to social media for children and it is testing bans, curfews and app time limits to see how they impact sleep, family life and schoolwork. Social media companies had designed algorithms that were intended to encourage addictive behavior, and parents were asking the government to intervene, Starmer said.

[...] More than 45,000 people had already responded to its consultation on children's online safety, the UK government said, adding that there was still time to contribute before a deadline of May 26. "We want to hear from mums and dads who are worried about the amount of time their children spend online and what they are viewing," Technology Secretary Liz Kendall said on Monday. "We want to hear from teenagers who know better than anyone what it is like to grow up in the age of social media. And we want to hear from families about their views on curfews, AI chatbots and addictive features."

An anonymous reader quotes a report from Bloomberg: Alphabet's Google is facing billions of dollars in potential damage claims as part of mass arbitration tied to the company's online search and advertising technology businesses, which courts have ruled were illegal monopolies. Advertisers are banding together to seek payouts through mass arbitration proceedings. While many companies that displayed ads purchased through Google -- including USA Today Co. and Advance Publications -- have sued for damages since the rulings in 2024, advertiser contracts with the search giant require mandatory arbitration over legal disputes.

In arbitration, legal disputes are handled by a mediator, a process that tends to favor companies in individual claims. Mass arbitration -- where 25 or more claims against the same company are pooled together -- have become more common and provide a greater likelihood of settlement awards for claimants. Ashley Keller, a Chicago lawyer whose firm has handled mass arbitrations against DoorDash, Postmates and TurboTax-maker Intuit, said he's already signed up a "significant number" of advertisers to participate in claims against Google. The first of those are expected to be filed this week.

"Two federal judges have already adjudicated Google to be a monopolist," Keller said in an interview with Bloomberg. "It seems sensible to seek redress." Keller, who is also representing Texas and other states in a lawsuit against Google for monopolization of advertising technology, estimates potential claims for online search and display ads could reach $218 billion or more, based on calculations from an economist his firm has hired. Similar mass arbitrations have lasted 12 to 24 months between the filing of claims and resolution, he said. "Given the nature of these matters, we cannot estimate a possible loss," Google said in a recent corporate filing. "We believe we have strong arguments against these open claims and will defend ourselves vigorously."

Researchers at the University of Southern California say they've developed a memristor memory device that continued operating at 700 degrees Celsius. "And crucially, 700 degrees was not the limit, it was simply as hot as their testing equipment could go," adds ScienceAlert. "The device showed no signs of failing." From the report: The device is called a memristor and it's a nanoscale component that can both store information and perform computing operations. Think of it as a tiny sandwich with two electrode layers on the outside and a thin ceramic filling in the middle. The team built theirs from tungsten, the metal with the highest melting point of any element, combined with a ceramic called hafnium oxide, and with a layer of graphene at the bottom. Each material can withstand enormous heat. Together, they turned out to be extraordinary.

What makes graphene the key ingredient is the way it interacts with tungsten at the atomic level. In a conventional device, heat causes metal atoms to drift slowly through the ceramic layer until they bridge the two electrodes, short circuiting everything and leaving the device permanently broken. Graphene stops that process dead. Its surface chemistry with tungsten is ... almost like oil and water. Tungsten atoms that drift toward the graphene find they simply cannot take hold, no anchor, no short circuit, no failure. The team used advanced electron microscopy and quantum level computer simulations to understand exactly why, turning a single lucky result into a repeatable principle. The findings have been published in the journal Science.

"The new Linux kernel was released and it's kind of a big deal," writes longtime Slashdot reader rexx mainframe. "Here is what you can expect." Linuxiac reports: A key update in Linux 7.0 is the removal of the experimental label from Rust support. That (of course) does not make Rust a dominant language in kernel development, but it is still an important step in its gradual integration into the project. Another notable security-related change is the addition of ML-DSA post-quantum signatures for kernel module authentication, while support for SHA-1-based module-signing schemes has been removed.

The kernel now includes BPF-based filtering for io_uring operations, providing administrators with improved control in restricted environments. Additionally, BTF type lookups are now faster due to binary search. At the same time, this release continues ongoing cleanup in the kernel's lower layers. The removal of linuxrc initrd code advances the transition to initramfs as the sole early-userspace boot mechanism.

Linux 7.0 also introduces NULLFS, an immutable and empty root filesystem designed for systems that mount the real root later. Plus, preemption handling is now simpler on most architectures, with further improvements to restartable sequences, workqueues, RCU internals, slab allocation, and type-based hardening. Filesystems and storage receive several updates as well. Non-blocking timestamp updates now function correctly, and filesystems must explicitly opt in to leases rather than receiving them by default. Phoronix has compiled a list of the many exciting changes.

Linus Torvalds himself announced the release, which can be downloaded directly from his git tree or from the kernel.org website.

Linux 7.0 has a major new version number but it's "largely a numbering reset [...], not a sign of some unusually disruptive release," notes Linuxiac.
