Slashdot reader alternative_right writes: Quantum computers need extreme cold to work, but the very systems that keep them cold also create noise that can destroy fragile quantum information. Scientists in Sweden have now flipped that problem on its head by building a tiny quantum refrigerator that actually uses noise to drive cooling instead of fighting it. By carefully steering heat at unimaginably small scales, the device can act as a refrigerator, heat engine, or energy amplifier inside quantum circuits.

Several security experts have "questioned the lack of technical detail" in that lawsuit alleging WhatsApp has no end-to-end encryption, reports the Washington Post: "It's pretty long on accusations and thin on any sort of evidence," Matthew Green, a cryptography professor at Johns Hopkins University, said over Signal. "WhatsApp has been very consistent about using end-to-end encryption. This lawsuit seems to be a nothingburger." Nicholas Weaver, a security researcher at the International Computer Science Institute, criticized the lawsuit in a post on Bluesky for lacking detail needed to back up its claims. "They don't even do a citation to the actual whistleblowers," he wrote, calling the suit "ludicrous." And Meta has done more than just deny the allegations: On Wednesday, WhatsApp sent a letter to [law firm] Quinn Emanuel threatening to seek sanctions against the firm's lawyers in court if they do not withdraw the suit, according to a copy reviewed by The Washington Post. "We're pursuing sanctions against Quinn Emanuel for filing a meritless lawsuit that was designed purely to grab headlines," Woog said by WhatsApp message. Woog also suggested the suit against WhatsApp was related to Quinn Emanuel's work on a separate case, between the social network giant and the spyware company NSO Group. The surveillance vendor is appealing a $167 million judgment entered against it in federal court last May, after a jury found that NSO's Pegasus tool exploited a weakness in the WhatsApp app to take over control of the phones of more than 1,000 users. An attorney from Quinn Emanuel joined NSO's legal team on that case on Jan. 22, according to legal filings, and different attorneys from that firm filed the case against WhatsApp on Jan. 23. "We believe a lawsuit like this is an attempt to launder false claims and divert attention from their dangerous spyware," Woog said. "It's very suspicious timing that this is happening as that appeal is happening," Maria Villegas Bravo, counsel at the Electronic Privacy Information Center, told the site Decrypt, "as NSO Group is trying to lobby to get delisted from sanctions in the U.S. government." EPIC's counsel also told the site that the complaint appears light on factual detail about WhatsApp's software: "I'm not seeing any factual allegations or any information about the actual software itself," Villegas Bravo said. "I have a lot of questions that I would want answered before I would want this lawsuit to proceed.... I don't think there's any merit in this lawsuit," Villegas Bravo said. Meta has forcefully rejected the allegations. In a statement shared with Decrypt, a company spokesperson called the claims "categorically false and absurd... WhatsApp has been end-to-end encrypted using the Signal protocol for a decade," the spokesperson said. "This lawsuit is a frivolous work of fiction, and we will pursue sanctions against plaintiffs' counsel."

The Daily Beast: "Salacious claims from Jeffrey Epstein that Bill Gates contracted an STD following 'sex with Russian girls,' and colluded with the disgraced financier on a plot to secretly slip his wife antibiotics, were revealed in the latest Epstein files release." The New York Times. (Alternate URL) "A representative of the Gates Foundation said, 'These claims — from a proven, disgruntled liar — are absolutely absurd and completely false. The only thing these documents demonstrate is Epstein's frustration that he did not have an ongoing relationship with Gates and the lengths he would go to entrap and defame.'" And Yahoo News points out the error of social media posts about the news: None paid attention to who actually wrote the email. The email was from Epstein — to Epstein... Both the "From" and "To" fields list Epstein's personal Gmail address. The message appears to be a draft, written during a period when Epstein's relationship with Gates had deteriorated. In it, Epstein alleges that Gates asked him to delete messages related to an STD. But the document does not show Gates making that request, nor does it provide independent confirmation that any of the claims are true. It reads like Epstein venting. It is not Gates confessing. "In a 2021 interview with CNN's Anderson Cooper, Gates called his relationship with the disgraced financier 'a huge mistake'," notes the New York Times. "He also sought to downplay his interactions with Epstein, saying he had several dinners with Epstein, with the hope of getting him to generate donations to the Gates Foundation."

They wear white coats and do many things a doctor would do — and their numbers are increasing rapidly.

An anonymous reader quotes a report from Wired: About a decade ago, many media outlets -- including WIRED -- zeroed in on a weird trend at the intersection of mental health, drug science, and Silicon Valley biohacking: microdosing, or the practice of taking a small amount of a psychedelic drug seeking not full-blown hallucinatory revels but gentler, more stable effects. Typically using psilocybin mushrooms or LSD, the archetypal microdoser sought less melting walls and open-eye kaleidoscopic visuals than boosts in mood and energy, like a gentle spring breeze blowing through the mind. Anecdotal reports pitched microdosing as a kind of psychedelic Swiss Army knife, providing everything from increased focus to a spiked libido and (perhaps most promisingly) lowered reported levels of depression. It was a miracle for many. Others remained wary. Could 5 percent of a dose of acid really do all that? A new, wide-ranging study by an Australian biopharma company suggests that microdosing's benefits may indeed be drastically overstated -- at least when it comes to addressing symptoms of clinical depression. A Phase 2B trial of 89 adult patients conducted by Melbourne-based MindBio Therapeutics, investigating the effects of microdosing LSD in the treatment of major depressive disorder, found that the psychedelic was actually outperformed by a placebo. Across an eight-week period, symptoms were gauged using the Montgomery-Asberg Depression Rating Scale (MADRS), a widely recognized tool for the clinical evaluation of depression. The study has not yet been published. But MindBio's CEO Justin Hanka recently released the top-line results on his LinkedIn, eager to show that his company was "in front of the curve in microdosing research." He called it "the most vigorous placebo controlled trial ever performed in microdosing." It found that patients dosed with a small amount of LSD (ranging from 4 to 20g, or micrograms, well below the threshold of a mind-blowing hallucinogenic dose) showed observable upticks in feelings of well-being, but worse MADRS scores, compared to patients given a placebo in the form of a caffeine pill. (Because patients in psychedelic trials typically expect some kind of mind-altering effect, studies are often blinded using so-called "active placebos," like caffeine or methylphenidate, which have their own observable psychoactive properties.) This means, essentially, that a medium-strength cup of coffee may prove more beneficial in treating major depressive disorder than a tiny dose of acid. Good news for habitual caffeine users, perhaps, but less so for researchers (and biopharma startups) counting on the efficacy of psychedelic microdosing. "It's probably a nail in the coffin of using microdosing to treat clinical depression," Hanka says. "It probably improves the way depressed people feel -- just not enough to be clinically significant or statistically meaningful."

Lennart Poettering has left Microsoft to co-found Amutable, a new Berlin-based company aiming to bring cryptographically verifiable integrity and deterministic trust guarantees to Linux systems. He said in a post on Mastodon that his "role in upstream maintenance for the Linux kernel will continue as it always has." Poettering will also continue to remain deeply involved in the systemd ecosystem. The Register reports: Linux celeb Lennart Poettering has left Microsoft and co-founded a new company, Amutable, with Chris Kuhl and Christian Brauner. Poettering is best known for systemd. After a lengthy stint at Red Hat, he joined Microsoft in 2022. Kuhl was a Microsoft employee until last year, and Brauner, who also joined Microsoft in 2022, left this month. [...] It is unclear why Poettering decided to leave Microsoft. We asked the company to comment but have not received a response. Other than the announcement of systemd 259 in December, Poettering's blog has been silent on the matter, aside from the announcement of Amutable this week. In its first post, the Amutable team wrote: "Over the coming months, we'll be pouring foundations for verification and building robust capabilities on top." It will be interesting to see what form this takes. In addition to Poettering, the lead developer of systemd, Amutable's team includes contributors and maintainers for projects such as Linux, Kubernetes, and containerd. Its members are also very familiar with the likes of Debian, Fedora, SUSE, and Ubuntu.

Researchers at the University of New South Wales are developing a "reverse solar panel" that generates small amounts of electricity at night by harvesting infrared heat radiated from Earth. "In the past, scientists have demonstrated that a 'thermoradiative diode' can convert infrared radiation directly into electricity; when used to convert heat from Earth, they exploit the temperature difference between Earth and the night sky, generating a current directly from heat," notes ExtremeTech. "This approach completely eliminates the need for heat to generate steam, though the resulting capacity is fairly low." From the report: The researchers estimate they could generate only about a watt per square meter, which isn't much. One reason for the low output is that the Earth's atmosphere lessens the heat differential that drives the generative process; in space, though, that's not an issue. Now, researchers believe that the ability to generate power in the moments between direct sunlight could help power satellites. That could be especially true in deep space, where periods without sunlight can be longer, and sunlight is often weaker; in these situations, losing electricity to heat loss is unacceptable. Many satellites already use heat to generate electricity, though with a much more rarified "thermoelectric generator" that uses rare, expensive materials like plutonium to create heat. With thermoradiative diodes, the heat source can be the Sun-warmed body of the satellite itself.

An anonymous reader quotes a report from the Guardian: The UK's first superfast-charging train running only on battery power will come into passenger service this weekend -- operating a five-mile return route in west London. Great Western Railway (GWR) will send the converted London Underground train out from 5.30am to cover the full Saturday timetable on the West Ealing to Greenford branch line, four stops and 12 minutes each way, and now carrying up to 273 passengers, should its celebrity stoke up the demand. The battery will recharge in just three and a half minutes back at West Ealing station between trips, using a 2,000kW charger connected to a few meters of rail that only becomes live when the train stops directly overhead. There are hopes within government and industry that this technology could one day replace diesel trains on routes that have proved difficult or expensive to electrify with overhead wires, as the decarbonization of rail continues. The train has proved itself capable of going more than 200 miles on a single charge -- last year setting a world record for the farthest travelled by a battery-electric train, smashing a German record set in 2021. The GWR train and the fast-charge technology has been trialled on the 2.5-mile line since early 2024, but has not yet carried paying passengers.
