Submission + - Using Sound Waves To Make Espresso Could Cut Coffee-Brewing Energy Use By 75% (theconversation.com)
An anonymous reader writes: We have developed what we call an ultrasonic espresso: a room-temperature brewing process that uses high-frequency sound waves to extract the flavour, oils, aroma and caffeine from coffee grounds. The result is an espresso-strength coffee made in under three minutes, but needing far less energy than the conventional method. Saving up to 75% of energy by not heating the water is a minor benefit for home users or small coffee shops. But for companies making ready-to-drink coffee products at industrial scale, it could be very significant indeed. A concentrated room-temperature coffee could be used directly in bottled drinks, milk-based beverages or cold coffee products. It can also be shipped as a concentrate and diluted later. This would reduce not only energy use, but potentially processing time as well.
The key to the new process is ultrasound. These are sound waves above the range of human hearing. In our system, a small metal device called a transducer presses against the side of a traditional espresso basket and makes it vibrate rapidly. Those vibrations move through the water and coffee grounds. This creates a phenomenon known as acoustic cavitation. Tiny bubbles form and collapse in the liquid. When these bubbles collapse near coffee particles, they produce microscopic jets and forces that act a little like scrubbing brushes. They pit and fracture the surface of the coffee grounds, helping flavor compounds, oils and caffeine move into the water much faster than they normally would at room temperature. In other words, ultrasound helps us replace heat with mechanical energy.
[...] In earlier work, we used ultrasound to speed up cold brew dramatically. But the challenge in this project was different: could we produce something with the strength, body and intensity of espresso, without heating the water? To do that, we adjusted several variables. Brew ratio was one of the most important: how much water we used for each gram of coffee. Too much water and the drink becomes diluted; too little and extraction becomes difficult. Grind size also mattered. Finer grounds allowed us to extract flavor more rapidly. Finally, we tested how long the ultrasound should be applied. We found the sweet spot was about two-and-a-half to three minutes. Of course, making a concentrated coffee in the laboratory is one thing. The real test is whether people want to drink it. [...] For the espresso samples, participants could not reliably tell the traditional and ultrasonic versions apart. There were no significant differences in aroma, flavor, bitterness or overall liking. For filter coffee, the ultrasound version was actually preferred overall, with participants rating its bitterness more pleasantly.

Submission + - OpenAI just exposed how bad AI still is at real science (nerds.xyz)
BrianFagioli writes: OpenAI introduced LifeSciBench, a new benchmark designed to evaluate AI systems on realistic life science research tasks rather than simple biology questions. While OpenAIâ(TM)s top-performing GPT-Rosalind model led the rankings, it achieved a pass rate of just 36.1 percent, failing nearly two-thirds of benchmark tasks. The company says the results highlight progress in scientific communication and evidence synthesis, but also reveal persistent weaknesses in artifact-heavy and design-oriented scientific work.
Submission + - Paint is already peeling in renovated Washington Reflecting Pool after 2 weeks. (cnn.com)
fahrbot-bot writes: CNN, Reuters and other sources are reporting that the paint on Washington's newly renovated Lincoln Memorial Reflecting Pool on Thursday was peeling away from the bottom and into the algae-tinted water, less than two weeks after announcement of the job's completion. The historic pool was drained and refinished in a $14.7 million no-bid contract.
Tim Auerhahn, a pool infrastructure expert and the chairman of the Aquatic Council, said it’s difficult to tell from the videos what was causing the “apparent delamination.”
“A coating system can fail for several reasons, including substrate preparation, surface contamination, application conditions, adhesion issues, product selection, mechanical damage, environmental exposure, or a combination of factors,” Auerhahn said.
The larger question, he added, is whether this represents a localized issue in that part of the pool or a larger, more systemic issue with the coating. “If the coating is losing adhesion in multiple locations, that could indicate a more significant concern,” he said.

She had remained hidden for decades, and the German police hadn't deployed facial recognition software to catch her. But according to the article a journalist did, to good effect.
Is the ban on the police using it a good thing? Is it good that a journalist was able to track her down using it?

Submission + - How to turn a 0day into a PR disaster: bully security researchers (heise.de)
Elektroschock writes: Microsoft bullied the publisher of BlueHammer (CVE-2026-33825), RedSun (CVE-2026-41091), UnDefend (CVE-2026-45498), YellowKey (CVE-2026-45585), and GreenPlasma/MiniPlasma (CVE-2020-17103 derivatives). A GitHub account was deleted, another account locked down, threats of international legal charges were made, and public law enforcement tipped off. That is a really unpleasant way to deal with a security nightmare of one’s own making. According to Microsoft, the courtesy of informing the Microsoft Security Response Center (MSRC) in advance was not extended. The researcher refutes that claim and speaks of layoffs of competent security staff, blocked accounts, and broken communication channels. There are also rumours of new formality requirements concerning video attachments.
Submission + - Researchers identify people through ordinary Wi-Fi with 99 percent-accuracy (tomshardware.com)
Baron_Yam writes: Security researchers at the Karlsruhe Institute of Technology (KIT) in Germany have published a paper demonstrating that unencrypted beamforming data broadcast by Wi-Fi devices during normal operation can be used to identify individuals walking through a room with 99.5% accuracy, regardless of whether the individuals are carrying Wi-Fi devices. The tactic leverages the router's beamforming tech to identify individuals with up to 99.5% accuracy, and it works with existing routers, too.
The system, called BFId, requires no specialized hardware, no access to the target Wi-Fi network, and works even if the person being tracked isn't carrying a wireless device. The team tested the attack on 197 participants, the largest dataset ever used in Wi-Fi-based identification works, and plans to present its findings at the ACM Conference on Computer and Communications Security (CCS) in Taipei.
See GitHub — https://github.com/ruvnet/RuVi... — for your own personal implementation requiring a couple of APs and a couple of ESP32 nodes. You can get full-home per-zone motion and occupancy detection fairly reliably, with the potential for pose detection and in optimal areas even respiration rate. With the right hardware and configuration, you can theoretically get heart rate too.

Submission + - Acer just announced a Debian Linux gaming handheld (nerds.xyz)
BrianFagioli writes: announced a new handheld gaming device called the Nitro Blaze Link, but unlike devices such as the Steam Deck or ASUS ROG Ally, this one is not trying to run games locally. Instead, Acer describes it as a “streaming-first” handheld designed to stream games from an existing gaming PC using Sunshine and Moonlight. The company says the device runs Debian Linux, includes a 7-inch WUXGA touchscreen, Wi-Fi 6, and weighs just 464 grams. Curiously, Acer never disclosed the processor powering the device, while the published specs list only 1GB RAM and 8GB eMMC storage.
The idea here seems pretty simple: instead of cramming increasingly power-hungry GPUs into portable gaming PCs, Acer is betting some gamers would rather have a lightweight Linux streaming terminal for couch gaming around the house. The Nitro Blaze Link is expected to launch in North America during Q4 2026, although Acer has not announced pricing yet.

Submission + - Pentagon says US military personnel targeted using commercial location data (msn.com) 1
JoeyRox writes: U.S. forces deployed to war zones have been targeted using commercially available location data, according to reports fielded by military officials, an illustration of how the global surveillance economy is shaping the battlefield.
In a letter shared with Reuters by U.S. Senator Ron Wyden, an Oregon Democrat, U.S. Central Command said it had "received multiple threat reports concerning adversary exploitation of commercial location data to target or surveil U.S. personnel in theater." The message, sent on April 14, offered no further specifics, but Centcom's area of responsibility includes the Gulf, where U.S. forces are facing off against the Iranian military over the Strait of Hormuz.

What [the National Design Studio] is doing is taking the parts of the federal government that touch you directly, your prescription, your voter registration, your passport, your federal login, out of the agencies that legally own them and rebuilding them on White House infrastructure. Vote.gov belongs to the Election Assistance Commission, and the studio built a copy. Passports belong to the State Department, and the studio is building a replacement this week. Login.gov belonged to GSA, and the studio’s guy runs it now.
Trump has said publicly that this infrastructure is for other presidents, and he is right about that. It is the one thing in this story I take him at his word on. The infrastructure outlasts him. Whoever wins in 2028 inherits the websites, the vendors, the data, and the hardware, sealed and waiting.

Submission + - Pope Leo Warns of Risks From AI In 42,300-Word Encyclical (nytimes.com)
An anonymous reader writes: Pope Leo XIV on Monday set out a sweeping vision for corporate executives, politicians and individuals who will shape and be shaped by the future of artificial intelligence, warning leaders to safeguard humanity from A.I.’s most disruptive effects. Leo’s declaration came in the form of a papal encyclical, an open letter to “all people of good will” that ran to roughly 42,300 words in its English version. It outlined his desire to protect human dignity and agency in an age in which technology threatens to replace humans in many professional and social roles. He presented it alongside Christopher Olah, a co-founder of Anthropic, a major A.I. developer, in a symbolic gesture of dialogue between leaders of the spiritual and technological worlds.
While emphasizing that “technology should not be considered, in itself, as a force antagonistic to humanity,” he wrote that “the pursuit of greater profits cannot justify choices that systematically sacrifice jobs.” Among other things, Leo called for:
— government regulation of the private companies that are driving the development of A.I.
— protection and retraining for workers whose jobs are threatened
— education to help students think critically about the technology
— action to protect children from violent, hypersexualized or fake information online that is often generated by A.I.
— safeguards to ensure that humans, not artificial intelligence, remain responsible for all decisions regarding the use of weapons.
Above all he emphasized the importance of retaining a fundamental social role for all human beings. “A society that guarantees employment to only a small fraction of the population, despite having a high level of technical development, risks exposing many to forced inactivity,” he wrote. “This creates a paradox of material progress and anthropological regression that undermines the foundations of a just and stable social peace,” he added.

Submission + - Friends rally to stop closure of historic solar observatory (cloudcroftreader.com)
D2inAlamo writes: NSF plans to plow under Sunspot Solar Observatory, at Sacramento Peak, NM, because of a mercury leak in the Dunn Solar Telescope. But, Friends of Sunspot are pushing back.
“Just because the telescope isn’t operational doesn’t mean the rest of the site’s still not viable,” Heidi Sanchez, president of the Sunspot Community Center, said in an article in the Cloudcroft Reader. “To spend all that money to demolish everything – our tax dollars could be used better than that.” Friends of Sunspot contend that the Dunn, built in 1969, could become a hands-on museum once the mercury is removed and the rest of the site renovated to provide an astronomy-oriented RV park and solar physics school.
Sunspot was started by the U.S. Air Force in 1947 as one of the first space weather forecasting stations. It quickly grew to support coronagraphic and patrol telescopes, and the Dunn, built in 1969. Although superseded by larger telescopes, even the NSF once acknowledged that the Dunn would be ideal for training future scientists who cannot access those facilities.
