alternative_right shares a report from Phys.org: Monitoring changes in water temperature and pressure at the seafloor can improve understanding of ocean circulation, climate, and natural hazards such as tsunamis. In recent years, scientists have begun gathering submarine measurements via an existing infrastructure network that spans millions of kilometers around the planet: the undersea fiber-optic telecommunications cables that provide us with amenities like Internet and phone service. Without interfering with their original purpose, the cables can be used as sensors to measure small variations in the light signals that run through them so that scientists can learn more about the sea. Meichen Liu and colleagues recently developed a new instrument, consisting of a receiver and a microwave intensity modulator placed at a shore station, that facilitates the approach. Their work is published in Geophysical Research Letters. Transcontinental fiber-optic cables are divided into subsections by repeaters, instruments positioned every 50 to 100 kilometers that boost information-carrying light signals so that they remain strong on the journey to their destination. At each repeater, an instrument called a fiber Bragg grating reflects a small amount of light back to the previous repeater to monitor the integrity of the cable. By observing and timing these reflections, the new instrument measures the changes in the time it takes for the light to travel between repeaters. These changes convey information about how the surrounding water changes the shape of the cable, and the researchers used that information to infer properties such as daily and weekly water temperature and tide patterns.

An anonymous reader quotes a report from Ars Technica: For some years now, detractors of battery electric vehicles have held up hydrogen as a clean fuel panacea. That sometimes refers to hydrogen combustion engines, but more often, it's hydrogen fuel cell electric vehicles, or FCEVs. Both promise motoring with only water emitted from the vehicles' exhausts. It's just that hydrogen actually kinda sucks as a fuel, and automaker Stellantis announced today that it is ending the development of its light-, medium- and heavy-duty FCEVs, which were meant to go into production later this year. Hydrogen's main selling point is that it's faster to fill a tank with the stuff than it is to recharge a lithium-ion battery. So it's a seductive alternative that suggests a driver can keep all the convenience of their gasoline engine with none of the climate change-causing side effects. But in reality, that's pretty far from true. [...] Between the high development costs and the fact that FCEVs only sell with strong incentives, the decision was made to cancel the production of hydrogen vans in France and Poland. Stellantis says there will be no job losses at its factories and that R&D staff will be put to work on other projects. "In a context where the Company is mobilizing to respond to demanding CO2 regulations in Europe, Stellantis has decided to discontinue its hydrogen fuel cell technology development program," said Jean-Philippe Imparato, chief operating officer for Enlarged Europe. "The hydrogen market remains a niche segment, with no prospects of mid-term economic sustainability. We must make clear and responsible choices to ensure our competitiveness and meet the expectations of our customers with our electric and hybrid passenger and light commercial vehicles offensive."

Longtime Slashdot reader Qbertino writes: Heise, a German IT news publisher, reports (English version via Google Translate) that the German state of Brandenburg is getting the world's tallest wind turbine, with an overall height of 300 meters (approximately 365 meters including rotor blades), designed to capture so-called third-level winds at higher altitudes. The article also includes a short 3D animation illustrating the construction and its size relative to standard modern wind turbines. The wind turbine uses a dual-framework base instead of a traditional closed tower to access stronger high-altitude winds, aiming to match offshore energy output while keeping onshore operating costs. According to Heise, the prototype could lead to the installation of up to 1,000 units across Germany -- fitting seamlessly between existing wind farms without needing extra land.

Scale AI is laying off 14% of its workforce and 500 contractors as part of a major restructuring just weeks after Meta bought a 49% stake and absorbed its CEO into a new superintelligence lab. The Verge reports: Jason Droege, CEO of Scale AI, sent an email to all Scale employees today, which was viewed by The Verge. Droege said he plans to restructure several parts of Scale's generative AI business and organize it from 16 pods to "the five most impactful": code, languages, experts, experimental, and audio. The company will also reorganize its go-to-market team into a single "demand generation" team that will have four pods, each covering a specific set of customers. "The reasons for these changes are straightforward: we ramped up our GenAI capacity too quickly over the past year," Droege wrote. "While that felt like the right decision at the time, it's clear this approach created inefficiencies and redundancies. We created too many layers, excessive bureaucracy, and unhelpful confusion about the team's mission. Shifts in market demand also required us to re-examine our plans and refine our approach." Droege said that he believes the changes to the company will make it more able to adapt to market shifts, serve existing customers, and win back customers that have "slowed down" work with Scale. He also said that the company would deprioritize generative AI projects with less growth potential. "We remain a well-resourced, well-funded company," he wrote. Scale's generative AI business unit will have an all-hands meeting tomorrow, followed by a company-wide meeting on July 18th. Osborne said that Scale plans to increase investment and hire hundreds of new employees in areas like enterprise, public sector, and international public sector, in the second half of 2025 and that severance has been paid out to impacted roles. "We're streamlining our data business to help us move faster and deliver even better data solutions to our GenAI customers," he said.

Longtime Slashdot reader bobdevine shares a report from OSTechNix: For the first time, Linux has officially broken the 5% desktop market share barrier in the United States of America! It's a huge milestone for open-source and our fantastic Linux community. While many might think of Linux as a niche choice, this new data shows a significant shift is happening. According to the latest StatCounter Global Stats for June 2025, Linux now holds 5.03% of the desktop operating system market share in the United United States of America. This is fantastic news! [...] One truly satisfying detail for me? Linux has finally surpassed the "Unknown" category in the USA! It shows that our growth is clear and recognized. "It took eight years to go from 1% to 2% (by April 2021), then just 2.2 years to reach 3% (June 2023), and a mere 0.7 years to hit 4% (February 2024)," notes the report. "Now, here we are, at over 5% in the USA! This exponential growth suggests that we're on a promising upward trend."

An anonymous reader quotes a report from TechCrunch: Security researchers say Chinese authorities are using a new type of malware to extract data from seized phones, allowing them to obtain text messages -- including from chat apps such as Signal -- images, location histories, audio recordings, contacts, and more. In a report shared exclusively with TechCrunch, mobile cybersecurity company Lookout detailed the hacking tool called Massistant, which the company said was developed by Chinese tech giant Xiamen Meiya Pico. Massistant, according to Lookout, is Android software used for the forensic extraction of data from mobile phones, meaning the authorities using it need to have physical access to those devices. While Lookout doesn't know for sure which Chinese police agencies are using the tool, its use is assumed widespread, which means Chinese residents, as well as travelers to China, should be aware of the tool's existence and the risks it poses. [...] The good news ... is that Massistant leaves evidence of its compromise on the seized device, meaning users can potentially identify and delete the malware, either because the hacking tool appears as an app, or can be found and deleted using more sophisticated tools such as the Android Debug Bridge, a command line tool that lets a user connect to a device through their computer. The bad news is that at the time of installing Massistant, the damage is done, and authorities already have the person's data. "It's a big concern. I think anybody who's traveling in the region needs to be aware that the device that they bring into the country could very well be confiscated and anything that's on it could be collected," said Kristina Balaam, a researcher at Lookout who analyzed the malware. "I think it's something everybody should be aware of if they're traveling in the region."

Steam has begun banning games that violate the payment rules of banks and card networks, targeting adult content in particular -- especially titles with extreme or controversial themes. Engadget reports: The new clause states that "content that may violate the rules and standards set forth by Steam's payment processors and related card networks and banks, or internet network providers" is not allowed and could result in removal from the platform. In other words, if credit card companies get mad about something, they could actually have the power to ban a game. The clause goes on to say that this will affect "certain kinds of adult-only content." This has likely already resulted in many games being pulled off the platform. SteamDB doesn't give a reason for these removals, but the timing does match up.
