Submission + - China Flies World's First Megawatt-Class Hydrogen Turboprop Engine (fuelcellsworks.com)

walterbyrd writes: China says the AEP100, a megawatt-class hydrogen-fueled turboprop engine developed by the Aero Engine Corporation of China, has completed its maiden flight on a 7.5-tonne unmanned cargo aircraft in Zhuzhou, Hunan. The 16-minute test covered 36km at 220km/h and 300 meters altitude, with the aircraft returning safely after completing its planned maneuvers. State media described it as the world’s first test flight of a megawatt-class hydrogen-fueled turboprop engine.

Submission + - Test to tell the difference between an AI making a mistake and choosing to lie (x.com)

schwit1 writes: Researchers built a test that can tell the difference between an AI making a mistake and an AI choosing to lie.

The results are terrifying.

They tested 30 of the most popular AI models in the world. GPT-4o. Claude. Gemini. DeepSeek. Llama. Grok. They asked each model a question. Then they checked whether the AI actually knew the correct answer. Then they pressured the AI to say something false.

The AI knew the truth. And it lied anyway.

Not once in a while. Not in rare edge cases. Grok lied 63% of the time. DeepSeek lied 53.5% of the time. GPT-4o lied 44.5% of the time. Not a single model scored above 46% honesty when pressured. Every model failed.

This is not hallucination. Hallucination is when the AI makes a mistake because it does not know the answer. This is different. The researchers proved the AI knew the correct answer first. Then it chose to say something false when it had a reason to.

The researchers asked GPT-4o to play a role where lying was useful. It lied. Then they removed the pressure, started a brand new conversation, and asked GPT-4o: "Was your previous answer true?" GPT-4o admitted it had lied.

83.6% of the time, the AI's own self-report matched the lies the researchers had already caught.

The AI knew it was lying. It did it anyway. And when you asked it afterward, it told you it lied.

Submission + - Masturbate more to lower your risk of cancer (nypost.com) 1

fjo3 writes: Dr. Lorelei Mucci, a professor of epidemiology at the Harvard T.H. Chan School of Public Health and a co-author of emerging research on prostate cancer and ejaculation, told The Post that her team has come across some interesting patterns.

Data from a long-term health and lifestyle study assessing more than 50,000 men since 1986 suggests that those who ejaculate 21 or more times per month had a 19-22% lower risk of prostate cancer than those who came less, she said.

“The ’21 or more’ isn’t a strict biological magic number, but rather a finding that emerged from our robust statistical analysis,” Mucci explained, adding that her team has even observed small reductions in risk for men who ejaculated only eight times per month.

Submission + - Tech Companies Are Trying to Neuter Colorado's Landmark Right-to-Repair Law (wired.com)

An anonymous reader writes: Today at a hearing of the Colorado Senate Business, Labor, and Technology committee, lawmakers voted unanimously to move Colorado state bill SB26-090—titled Exempt Critical Infrastructure from Right to Repair—out of committee and into the state senate and house for a vote. The bill modifies Colorado’s Consumer Right to Repair Digital Electronic Equipment act, which was passed in 2024 and went into effect in January 2026. While the protections secured by that act are wide, the new SB26-090 bill aims to “exempt information technology equipment that is intended for use in critical infrastructure from Colorado's consumer right to repair laws.”

The bill is supported by tech manufacturers like Cisco and IBM, according to lobbying disclosures. These are companies that have vested interests in manufacturing things like routers, server equipment, and computers and stand to profit if they can control who fixes their products and the tools, components, and software used to make those upgrades and repairs. They also cite cybersecurity concerns, saying that giving people access to the tools and systems they would need to repair a device could also enable bad actors to use those methods for nefarious means. (This is a common argument manufacturers make when opposing right-to-repair laws.)

[...] During the hearing, more than a dozen repair advocates spoke from organizations like Pirg, the Repair Association, and iFixit opposing the bill. YouTuber and repair advocate Louis Rossmann was there. The main problem, repair advocates say, is that the bill deliberately uses vague language to make the case for controlling who can fix their products. “The ‘information technology’ and ‘critical infrastructure’ thing is as cynical as you can possibly be about it,” says Nathan Proctor, the leader of Pirg’s US right-to-repair campaign. “It sounds scary to lawmakers, but it just means the internet.” [...]

The Colorado Labor and Technology committee advanced the bill, but it still needs to go through votes on the Colorado Senate and House floors before going into effect. Those votes may take place as early as next week. Regardless of how the bill goes in the state, it’s likely that manufacturers will continue their push to alter or undo repair legislation in other states across the country. “This only hardens my resolve,” Proctor says. “We cannot stop until this problem is addressed. In practice everywhere, people need to be able to fix their stuff. This is proof that we have to keep going.”

Submission + - Python blood could hold the secret to healthy weight loss (colorado.edu)

fahrbot-bot writes: CU Boulder researchers are reporting that they have discovered an appetite-suppressing compound in python blood that helps the snakes consume enormous meals and go months without eating yet remain metabolically healthy. The findings were published in the journal Natural Metabolism on March 19, 2026.

Pythons can grow as big as a telephone pole, swallow an antelope whole, and go months or even years without eating—all while maintaining a healthy heart and plenty of muscle mass. In the hours after they eat, research has shown, their heart expands 25% and their metabolism speeds up 4,000-fold to help them digest their meal.

The team measured blood samples from ball pythons and Burmese pythons, fed once every 28 days, immediately after they ate a meal. In all, they found 208 metabolites that increased significantly after the pythons ate. One molecule, called para-tyramine-O-sulfate (pTOS) soared 1,000-fold.

Further studies, done with Baylor University researchers, showed that when they gave high doses of pTOS to obese or lean mice, it acted on the hypothalamus, the appetite center of the brain, prompting weight loss without causing gastrointestinal problems, muscle loss or declines in energy.

The study found that pTOS, which is produced by the snake’s gut bacteria, is not present in mice naturally. It is present in human urine at low levels and does increase somewhat after a meal. But because most research is done in mice or rats, pTOS has been overlooked.

Submission + - Judges given approval to use AI to write legal opinions (apnews.com)

Press2ToContinue writes: From the "What-Could-Possibly-Go-Wrong" department:

LONDON (AP) — England’s 1,000-year-old legal system — still steeped in traditions that include wearing wigs and robes — has taken a cautious step into the future by giving judges permission to use artificial intelligence to help produce rulings.

The Courts and Tribunals Judiciary last month said AI could help write opinions but stressed it shouldn’t be used for research or legal analyses because the technology can fabricate information and provide misleading, inaccurate and biased information.

“Judges do not need to shun the careful use of AI,” said Master of the Rolls Geoffrey Vos, the second-highest ranking judge in England and Wales. “But they must ensure that they protect confidence and take full personal responsibility for everything they produce.”

At a time when scholars and legal experts are pondering a future when AI could replace lawyers, help select jurors or even decide cases, the approach spelled out Dec. 11 by the judiciary is restrained. But for a profession slow to embrace technological change, it’s a proactive step as government and industry — and society in general — react to a rapidly advancing technology alternately portrayed as a panacea and a menace.

Selling Incandescent Light Bulbs As Heating Devices 557

Csiko writes "The European Union has banned by law trading of incandescent light bulbs due to their bad efficiency/ecology (most of the energy is transformed into heat). A company is now trying to bypass this restriction by offering their incandescent light bulb products as a heating device (article in German) instead of a light device. Still, their 'heat balls' give light as well as heating. So — every law can be bypassed if you have some creativity!"

Android and the Linux Kernel Community 354

An anonymous reader links to Greg Kroah-Hartman's explanation of a rift (hopefully mendable) in the development culture of Google's Linux-based Android OS and the Linux kernel itself. "As the Android kernel code is now gone from the Linux kernel, as of the 2.6.33 kernel release, I'm starting to get a lot of questions about what happened, and what to do next with regards to Android. So here's my opinion on the whole matter ..."

Exoplanet Has Showers of Pebbles 341

mmmscience writes "The newly-discovered exoplanet COROT-7b has an unusual form of precipitation: rocks. Because it orbits so close to its sun, the temperature on its sun-facing side is around 4220 degrees Fahrenheit. That's hot enough for rocks to vaporize — not unlike water evaporating on Earth. And, like Earth, when the vapor cools in the upper atmosphere, it forms clouds and begins to rain. But instead of water, COROT-7b gets a shower of pebbles."

Burglar Logs Into Facebook On Victim's Computer 337

yet-another-lobbyist writes to mention that Facebook addiction has finally caused real world consequences, at least for one would-be burglar. It seems that 19-year-old Jonathan Parker couldn't stay away from the popular social networking site, even long enough to rob a house. Parker not only stopped mid-robbery to check his Facebook status on the victim's computer, but left it logged in to his account when he left.

Supermarket Bans Jedi Knight 169

The employees at Tesco seem to be immune to mind tricks, and have kicked out the founder of the International Church of Jediism. Daniel Jones, 23, who founded the religion based on the Star Wars movies, was asked to leave because his robes were against store rules which forbid the wearing of 'hoodies' in their premises. "I told them it was a requirement of my religion but they just sniggered and ordered me to leave," he told The Daily Telegraph newspaper. "I walked past a Muslim lady in a veil. Surely the same rules should apply to everyone." It's exactly this kind of stuff that turns young Jedis to the dark side.

Birdsong Studies Lead To a Revolution In Biology 117

Smithsonian.com covers research that began with the study of birdsong and ended by overturning the common belief that adult animals can't produce new brain cells. "Deconstructing birdsong may seem an unlikely way to shake up biology. But [Fernando] Nottebohm's research has shattered the belief that a brain gets its quota of nerve cells shortly after birth and stands by helplessly as one by one they die — a 'fact' drummed into every schoolkid's skull. [Nottebohm] demonstrated two decades ago that the brain of a male songbird grows fresh nerve cells in the fall to replace those that die off in summer. The findings were shocking, and scientists voiced skepticism that the adult human brain had the same knack for regeneration. ... Yet, inspired by Nottebohm's work, researchers went on to find that other adult animals — including human beings — are indeed capable of producing new brain cells. And in February, scientists reported for the first time that brand-new nerves in adult mouse brains appeared to conduct impulses — a finding that addressed lingering concerns that newly formed adult neurons might not function."

Taking Showers Can Be Harmful To Your Health 431

TheClockworkSoul writes "According to both the BBC and NewScientist, showering may be bad for your health. Apparently, dirty shower heads can be an ideal breeding ground for Mycobacterium avium, a bug responsible for a type of pulmonary disease more prevalent than tuberculosis in developed countries, cases of which have risen in parallel with the rise in showering. Tests revealed nearly a third of devices harbor significant levels of the critter."
