Copper's Surprising Melting Behavior Provides Insights for Future Fusion Power Plant Design

6:51
Phys.org reports: Future fusion power plants aim to recreate the heart of a star here on Earth to power our future energy needs. While the core fusion plasma will burn at hundreds of millions of degrees, the surrounding structural components must handle sudden, punishing heat loads that rival the extreme temperatures faced by spacecraft upon reentry into Earth's atmosphere. Copper and its alloys are primary candidates for handling these intense heat fluctuations, making it vital to understand e…

X Open Sources Its Ranking and Filtering Algorithms

4:42
An anonymous reader shared this report from TechCrunch: X is significantly expanding its open source codebase, which includes the app's "For You" algorithm and its core ranking engine, and adding a feature that will let users see if their account or posts have been impacted by any of its ranking systems, the social network said on Thursday. The company is making the source code for the "For You" timeline, the default feed you see when you open the app, available on GitHub under the Apache v2 li…

Why Europe Keeps Being Pummeled by Heat Waves

2:02
Europe is facing its fifth round of dangerously high temperatures this summer, the New York Times reports. Now climate scientists wonder if global warming is doing more than raise temperatures... The weather patterns that create heat domes aren't new, but today they arise on top of the warming caused by greenhouse gas emissions. That makes it more likely that heat waves reach record-shattering temperatures for long stretches. But other environmental changes — natural, human-influenced or both —…

How Swarming Jellyfish Overran Three French Nuclear Power Reactors

0:58
A "massive influx" of jellyfish forced Electricite de France SA to shut three units at its Gravelines nuclear power plant this week and reduce output at a fourth, reports Bloomberg. Just as summer temperatures surged, 3.2 gigawatts went offline — and the power utility was already facing cuts other nuclear sites as high temperatures reduced the river water available for cooling. More details from ScienceAlert: As Politico reports, the Gravelines nuclear power plant spent hundreds of thousands of…

How Larry Ellison Dropped From World's 2nd-Richest To No. 8 In Just 2 Months

22:51
Less than a year ago he was the #1 richest man in the world. 10 weeks ago he was #2. But yesterday Larry Ellison dropped to #8, Forbes reports, falling behind Nvidia CEO Jensen Huang. Ellison's net worth is now estimated at just $192.6 billion — after a $104 billion decline: Shares of Oracle plunged roughly 54% between hitting a high of just over $250 on June 1 to a low of $114.50 on July 28, though the stock rebounded slightly to $150.52 as of Friday. A decline followed Oracle telling investor…

AI Fails to Deliver a 4-Day Work Week - Especially at AI Companies

21:16
"An engineering director at Google said four years ago that AI would deliver a four-day work week by 2025," remembers the BBC. And earlier this year OpenAI "formally urged companies to start testing out a four-day work week (with no change in pay), claiming that AI will soon be able to speed up so much human labour that the corporate world should prepare itself." However, a former OpenAI technical employee who left the company last year told the BBC the firm never actually trialled the four-day…

It's Not Just RAM: Windows Licenses Are Also Pushing Up PC Prices

20:12
It's not just RAM prices that are going up, writes CNET. "Reports suggest the cost of Windows licenses for manufacturers is rising by up to 10%." Several sites that closely follow Microsoft news, including Windows Central and Windows Latest, have published articles citing a report from Taiwan's Economic Daily News that claims some PC manufacturers are seeing a 7% to 10% increase in the cost of Windows 11 licenses... Because they buy licenses in bulk, they get a sizeable discount over what a con…

Europe's Record Heatwave Kills 25,000, Dries Rivers, Shuts Nuclear Plant, Exposes Submerged Warships

19:09
"The European Union's Copernicus climate monitoring service confirmed Monday that June and July were the hottest on record in western Europe," .according to a report from the CBC. "The period saw an estimated 25,000 heat-related deaths." CNN has before-and-after photos of Europe's dried rivers, calling it "a crisis so dire it can be seen from space" River levels are so low that commercial ships have had to reduce their loads by as much as 80% to avoid running aground. It's disrupting supply cha…

Why Are Big Tech CEOs Writing Long Manifestos About AI?

18:05
This week Meta CEO Mark Zuckerberg published a 6,500 word open letter titled "The Future is for Everyone". But the BBC is more interested in why big tech executives keep writing manifestos about AI: [Zuckerberg's] vision echoes what AI leaders have expressed in various forms: the product they are building is among the "most important technologies in history." Marc Andreessen, co-founder of early web titan Netscape, perhaps started this trend in 2023 with a 5,000-word essay he called "The Techno…

Vulnerability Giving Attackers Full Control of Macs Is Under Active Exploitation

17:33
joshuark shares a report from Ars Technica: Dutch officials have warned that a high-severity macOS vulnerability that allows attackers to execute malicious code is under active exploitation. "The NCSC has received a notification indicating that active abuse of this vulnerability has been observed on multiple systems on which port 5900 was accessible from the Internet," the Netherlands National Cyber Security Centrum warned earlier this week. "In all these cases, root had been accessed on the af…

Astronomers Discover a New Kind of Cosmic Object: a Black Hole 'Star'

13:18
Astronomers using the James Webb Space Telescope say they may have found a new class of object: a "black hole star," in which a black hole is wrapped in dense gas and radiates in ways that resemble an enormous star. The Guardian reports: The international team made the breakthrough after focusing their attention on a mysterious red spot in images of the early universe captured by Nasa's James Webb space telescope. The object was lurking in the constellation of Cetus, the Whale, billions of ligh…

Meta Patents AI Glasses to Use Facial Recognition to Identify People, Make Highlight Reels of Your Dinner Party

9:34
Meta has patented a smart-glasses system that could use facial recognition to identify people and automatically create personalized highlight reels of events such as dinner parties. The patent doesn't guarantee the feature will ship, but it offers a detailed look at how Meta is exploring facial recognition and AI-powered memory capture for its wearable devices. 404 Media reports: "I've generated some highlights of tonight's dinner party. Would you like to see them?" a prompt from the system say…

Robots That Walk and Talk Are Coming To Car Factories

15.srpna
An anonymous reader quotes a report from The New York Times: At a BMW factory in South Carolina, a human-shaped robot with a screen for a face recently stepped from a charging station toward a stack of green plastic boxes. It grasped an auto part from one of the boxes, pivoted, placed the part in a trolley, then pulled the trolley across the floor. The robot's slow, stiff movements suggested a worker with a bad hangover rather than a technological revolution. "They're still slower than humans,"…

Flock Safety is tightening controls on its nationwide license plate reader network after mounting backlash over privacy and documented police misuse. By January 1, law enforcement customers will be required to use automated auditing, tie searches to specific case numbers, and accept a shorter seven-day default retention period. Critics, including the ACLU, argue the changes still leave too much surveillance power in police hands. The Associated Press reports: In an interview, Flock CEO Garrett …
