20 miles west of Portland, engineers at an Intel lab are dunking expensive racks of servers "in a clear bath" made of motor oil-like petrochemicals, reports the Oregonian, where the servers "give off a greenish glow as they silently labor away on ordinary computing tasks." Intel's submerged computers operate just as they would on a dry server rack because they're not bathing in water, even though it looks just like it. They're soaking in a synthetic oil that doesn't conduct electricity. So the computers don't short out. They thrive, in fact, because the fluid absorbs the heat from the hardworking computers much better than air does. It's the same reason a hot pan cools off a lot more quickly if you soak it in water than if you leave it on the stove. As data centers grow increasingly powerful, the computers are generating so much heat that cooling them uses exorbitant amounts of energy. The cooling systems can use as much electricity as the computers themselves. So Intel and other big tech companies are designing liquid cooling systems that could use far less electricity, hoping to lower data centers' energy costs by as much as a third — and reducing the facilities' climate impact. It's a wholesale change in thinking for data centers, which already account for 2% of all the electricity consumption in the U.S... Skeptics caution that it may be difficult or prohibitively expensive to overhaul existing data centers to adapt to liquid cooling. Advocates of the shift, including Intel, say a transition is imperative to accommodate data centers' growing thirst for power. "It's really starting to come to a head as we're hitting the energy crisis and the need for climate action globally," said Jen Huffstetler, Intel's chief product sustainability officer... Cooler computers can be packed more tightly together in data centers, since they don't need space for airflow. Computer manufacturers can pack chips together more tightly on the motherboard, enabling more computing power in the same space. And liquid cooling could significantly reduce data centers' environmental and economic costs. Conventional data centers' evaporative cooling systems require tremendous volumes of water and huge amounts of electricity... Many other tech companies are backing immersion cooling, too. Google, Facebook and Microsoft are all helping fund immersion cooling research at Oregon State... [T]he timing may finally be right for data centers operators to make the shift away from air cooling to something far more efficient. Intel's Huffstetler said she expects to see liquid cooling become widespread in the next three to five years. The article notes other challenges: liquid adds more weight than some buildings' upper floors can support Some metals degrade faster in liquid than they do in air. And the engineers had to modify the servers by removing their fans — "because they serve no purpose while immersed."

Long-time Slashdot reader destinyland writes: CBS News interviewed 71-year-old Mark Hamill, who remembers that in his first audition for Star Wars, they didn't give him the whole script. So "I couldn't figure out, is this like a send-up of Flash Gordon or whatever? You couldn't tell. Because nobody talks like this!" Hamill also does impressions of the other actors he worked with. "I was asking Harrison, because he had been in American Graffiti. I said, 'You know George. Is this like a joke, or — should we send it up, make fun of it?'" And then he mimics Harrison Ford as saying "Yeah, Whatever. Get it done." ("So he was no help.") Later Hamill also describes meeting Alec Guinness, who eventually had to remind Hamill to stop calling him "Sir Alec." ("I want to be known by my name, not my accolade...") And after playing Mozart in the Broadway production of Amadeus, Hamill remembers the reaction when he'd suggested appearing in the movie adaptation. Director Milos Forman said, "Oh ho ho ho. No, no, no. The Luke Skywalker is not to be being the Mozart." (Hamill's reaction? "At least he's honest.") There's a clip of Hamill doing voice-over work for the animated Batman series, and (about three minutes in) a quick clip from Mark Hamill's 1976 screen test with Harrison Ford. There's even a photo of Hamill's appearance in a 1971 episode of The Partridge Family. At the end of the interview, Hamill doesn't say whether or not he'll ever reappear in the role of Luke Skywalker again. "You never say never. I just don't see any reason to, let me put it that way. They have so many stories to tell, they don't need Luke any more." But the interviewer points out that "if you find yourself in Ukraine during an air strike, you might hear Luke Skywalker's voice talking you down" -- since he also provides the voice for a warning app linked to Ukraine's air defense system.

UBS Group completed the deal to acquire former rival Credit Suisse Group, sealing the biggest merger in banking since the 2008 financial crisis and creating a global wealth-management titan. From a report: The Swiss bank announced the closing of the deal in an open letter in local and international newspapers on Monday. The takeover of Credit Suisse ends the lender's 167-year independent existence. The announcement caps more than two months of uncertainty for employees after UBS finalized negotiations with the Swiss government over a 9 billion Swiss franc ($10 billion) guarantee against potential losses on Credit Suisse assets. The deal sets UBS up for a windfall gain in the tens of billions of dollars and begins a period of complex integration likely to involve thousands of job cuts.

"Kairan Quazi will probably need someone to drive him to work at SpaceX," writes the Los Angeles Times — because "He's only 14." The teen is scheduled to graduate this month from the Santa Clara University School of Engineering before starting a job as a software engineer at the satellite communications and spacecraft manufacturer... The soft-spoken teen said working with Starlink — the satellite internet team at SpaceX — will allow him to be part of something bigger than himself. That is no small feat for someone who has accomplished so much at such a young age... The youngster jumped from third grade to a community college, with a workload that he felt made sense. "I felt like I was learning at the level that I was meant to learn," said Kairan, who later transferred to Santa Clara University... Kairan's family told BrainGain Magazine that when he was 9, IQ tests showed that his intelligence was in the 99.9th percentile of the general population. Asked if he's a genius, he recalled his parents telling him, "Genius is an action â it requires solving big problems that have a human impact." Once accepted to the engineering school at Santa Clara University as a transfer student, Kairan felt that he had found his freedom to pursue a career path that allowed him to solve those big problems. While in college, Kairan and his mother made a list of places where he could apply for an internship. Only one company responded. Lama Nachman, director of the Intelligent Systems Research Lab at Intel, took a meeting with 10-year-old Kairan, who expected it to be brief and thought she would give him the customary "try again in a few years," he said. She accepted him. "In a sea of so many 'no's' by Silicon Valley's most vaunted companies, that ONE leader saying yes ... one door opening ... changed everything," Kairan wrote on his LinkedIn page... Asked what he plans to wear on his first day, Kairan joked in an email that he plans "to show up in head to toe SpaceX merch. I'll be a walking commercial! Joking aside, I'll probably wear jeans and a t-shirt so I can be taken seriously as an engineer."

A New York Times columnist considers alternate reasons for the upcoming House hearings with a whistleblower former intelligence official, David Grusch, who claims the US government possesses "intact and partially intact" alien vehicles: This whistle-blower's mere existence is evidence of a fascinating shift in public U.F.O. discourse. There may not be alien spacecraft, but there is clearly now a faction within the national security complex that wants Americans to think there might be alien spacecraft, to give these stories credence rather than dismissal. The evidence for this shift includes the military's newfound willingness to disclose weird atmospheric encounters. It includes the establishment of the task force that Grusch was assigned to... It also includes other examples of credentialed figures, like the Stanford pathology professor Garry Nolan, who claim they're being handed evidence of extraterrestrial contact. And it includes the range of strange stories being fed to writers willing to operate in the weird-science zone... I have no definite theory of why this push is happening. Maybe it's because there really is something Out There and we're being prepared for the big reveal... [M]aybe it's a cynical effort to use unexplained phenomena as an excuse to goose military funding. Or maybe it's a psy-op to discredit critics of the national security state...

Next year Intel introduces a new transistor — RibbonFET — and a new way of powering it called "PowerVia." This so-called "backside power" approach "aims to separate power and I/O wiring, shifting power lines to the back of the wafer," reports Tom's Hardware, which "eliminates any possible interference between the data and power wires and increases logic transistor density." IEEE Spectrum explains this approach "leaves more room for the data interconnects above the silicon," while "the power interconnects can be made larger and therefore less resistive." And Intel has already done some successful powering tests using it on Intel's current transistors: The resulting cores saw more than a 6 percent frequency boost as well as more compact designs and 30 percent less power loss. Just as important, the tests proved that including backside power doesn't make the chips more costly, less reliable, or more difficult to test for defects. Intel is presenting the details of these tests in Tokyo next week at the IEEE Symposium on VLSI Technology and Circuits... [C]ores can be made more compact, decreasing the length of interconnects between logic cells, which speeds things up. When the standard logic cells that make up the processor core are laid out on the chip, interconnect congestion keeps them from packing together perfectly, leaving loads of blank space between the cells. With less congestion among the data interconnects, the cells fit together more tightly, with some portions up to 95 percent filled... What's more, the lack of congestion allowed some of the smallest interconnects to spread out a bit, reducing parasitic capacitance that hinders performance... With the process for PowerVia worked out, the only change Intel will have to make in order to complete its move from Intel 4 to the next node, called 20A, is to the transistor... Success would put Intel ahead of TSMC and Samsung, in offering both nanosheet transistors and backside power.

An anonymous reader shared this report from Insider: The recent tsunami of tech layoffs could leave a wave of union organizing in its wake. That's according to Skylar Hinnant, a senior QA tester at Microsoft's ZeniMax, who supported a successful union campaign at the gaming unit of the software giant... Within tech companies, roles such as quality assurance testers and contractors are less revered, so those workers are more likely to unionize, Hinnant explained. "In these roles, people will be treated differently, it's sort of derogatory," he added. Layoffs, cuts in perks, and other benefits, and a slowing of pay increases have marred the tech industry's reputation as a great place to work. That has kicked off a power struggle between employees and management. "When an employer lays off 16,000 employees in a day, that's a power play making employees realize how powerless they are," Rahul Dhaundiyal, a director of engineering at Indeed, told Insider... Dhaundiyal agreed with Hinnant that for lower-level tech workers the call to unionize rings louder. "In certain lower paid jobs where decision-making is top-down, where you are seen as a resource and not a human being to invest in, those kinds of roles end up maximizing disbalance and would unionize first," Dhaundiyal said.

The international space station is equpped with four 39-foot blankets (11.8-meters), reports CBS News. The first one was delivered in December of 2000 — and now it's time for some changes: Two astronauts ventured outside the International Space Station Friday and installed the fifth of six roll-out solar array blankets — iROSAs — needed to offset age-related degradation and micrometeoroid damage to the lab's original solar wings. Floating in the Quest airlock, veteran Stephen Bowen, making his ninth spacewalk, and crewmate Woody Hoburg, making his first, switched their spacesuits to battery power at 9:25 a.m. EDT, officially kicking off the 264th spacewalk devoted to ISS assembly and maintenance and the seventh so far this year. NASA is in the process of upgrading the ISS's solar power system by adding six iROSAs to the lab's eight existing U.S. arrays. The first four roll-out blankets were installed during spacewalks in 2021 and 2022. Bowen and Hoburg installed the fifth during Friday's spacewalk and plan to deploy the sixth during another excursion next Thursday. The two new iROSAs were delivered to the space station earlier this week in the unpressurized trunk section of a SpaceX cargo Dragon. The lab's robot arm pulled them out Wednesday and mounted them on the right side of the station's power truss just inboard the starboard wings... As the station sailed 260 miles above the Great Lakes, the 63-foot-long solar array slowly unwound like a window shade to its full length. Well ahead of schedule by that point, the spacewalkers carried out a variety of get-ahead tasks to save time next week when they float back outside to install the second new iROSA. They returned to the airlock and began re-pressurization procedures at 3:28 p.m., bringing the 6-hour three-minute spacewalk to a close. With nine spacewalks totaling 60 hours and 22 minutes under his belt, Bowen now ranks fifth on the list of the world's most experienced spacewalkers. "Combined with the 95-kilowatt output of the original eight panels, the station's upgraded system will provide about 215,000 kilowatts of power."

InfoWorld explores how the new Mojo program language "resembles Python, how it's different, and what it has to offer." The newly unveiled Mojo language is being promoted as the best of multiple worlds: the ease of use and clear syntax of Python, with the speed and memory safety of Rust. Those are bold claims, and since Mojo is still in the very early stages of development, it will be some time before users can see for themselves how the language lives up to them. But Mojo's originator — a company named Modular — has provided early access [through a limited-enrollment preview program] to an online playground: a Jupyter Notebook environment where users can run Mojo code and learn about the language's features and behavior... Mojo can be described as a "superset" of Python. Programs written in Python are valid Mojo programs, although some Python behaviors haven't yet been implemented... It's also possible to use the actual Python runtime for working with existing Python modules, although there is a performance cost. When Mojo introduces new syntax, it's for system-level programming features, chiefly manual memory handling. In other words, you can write Python code (or something almost exactly like it) for casual use cases, then use Mojo for more advanced, performance-intensive programming scenarios... Mojo's other big difference from Python is that Mojo's not interpreted through a runtime, as Python is. Mojo is compiled ahead-of-time to machine-native code, using the LLVM toolchain. To that end, the best performance comes from using features specific to Mojo. Python features are likely to come at the cost of emulating Python's dynamic behaviors, which are inherently slow — or again, by just using the Python runtime. Many of Mojo's native language features do one of two things. They're either entirely new features not found in Python at all, or expansions of a Python feature that make it more performant, although with less of Python's dynamism. For example, Mojo has its own fn keyword which defines a function with explicitly-typed and immutable-by-default arguments, and its own struct keyword which is less like a Python class and more like its C/C++ and Rust counterpart "with fixed layouts determined at compile time but optimized for machine-native speed." But "At a glance, the code closely resembles Python. Even the new Mojo-specific keywords integrate well with existing Python syntax, so you can run your eye down the code and get a general idea of what's happening." And then there's the speed... The notebook demos also give examples of how Mojo code can be accelerated via parallelism, vectorizing, and "tiling" (increasing cache locality for operations). One of the demos, a 128x128 matrix multiplication demo, yielded a claimed 17-times speedup over Python (using the Python runtime in the Mojo playground) by simply running as-is with no special modification. Mojo added 1866x speedup by adding type annotations, 8500x speedup by adding vectorized operations, and 15000x speedup by adding parallelization.

Researchers at a London-based public research university had already discovered that for 5-10% of people with hypertension, the cause is a gene mutation in their adrenal glands. (The mutation results in excessive production of a hormone called aldosterone.) But that was only the beginning, according to a new announcement from the university shared by SciTechDaily: Clinicians at Queen Mary University of London and Barts Hospital have identified a gene variant that causes a common type of hypertension (high blood pressure) and a way to cure it, new research published in the journal Nature Genetics shows. The cause is a tiny benign nodule, present in one-in-twenty people with hypertension. The nodule produces a hormone, aldosterone, that controls how much salt is in the body. The new discovery is a gene variant in some of these nodules which leads to a vast, but intermittent, over-production of the hormone. The gene variant discovered today causes several problems which makes it hard for doctors to diagnose some patients with hypertension. Firstly, the variant affects a protein called CADM1 and stops cells in the body from 'talking' to each other and saying that it is time to stop making aldosterone. The fluctuating release of aldosterone throughout the day is also an issue for doctors, which at its peak causes salt overload and hypertension. This fluctuation explains why patients with the gene variant can elude diagnosis unless they happen to have blood tests at different times of day. The researchers also discovered that this form of hypertension could be cured by unilateral adrenalectomy — removing one of the two adrenal glands. Following removal, previously severe hypertension despite treatment with multiple drugs disappeared, with no treatment required through many subsequent years of observation. Fewer than 1% of people with hypertension caused by aldosterone are identified because aldosterone is not routinely measured as a possible cause. The researchers are recommending that aldosterone is measured through a 24-hour urine test rather than one-off blood measurements, which will discover more people living with hypertension but going undiagnosed.

In less than two years, NASA plans to have astronauts walking on the moon again — the first time in over half a century. "And one potential surprise could be detecting life on the moon," reports Space.com: New research suggests that future visitors to the lunar south pole region should be on the lookout for evidence of life in super-cold permanently shadowed craters — organisms that could have made the trek from Earth. Microbial life could potentially survive in the harsh conditions near the lunar south pole, suggested Prabal Saxena, a planetary researcher at NASA's Goddard Space Flight Center in Greenbelt, Maryland. "One of the most striking things our team has found is that, given recent research on the ranges in which certain microbial life can survive, there may be potentially habitable niches for such life in relatively protected areas on some airless bodies," Saxena told Space.com. Indeed, the lunar south pole may possess the properties that can enable survival and potentially even episodic growth of certain microbial life, Saxena said. "We're currently working on understanding which specific organisms may be most suited for surviving in such regions and what areas of the lunar polar regions, including places of interest relevant to exploration, may be most amenable to supporting life," he said. In work presented at a recent science workshop on the potential Artemis 3 landing sites, Saxena and study members reported that the lunar south pole may contain substantial surface niches that could be potentially habitable for a number of microorganisms. While it's possible organic molecules from earth might have been hurled to the moon after a meteor impact, there's a much more likely possibility. A NASA organic geochemist on the study views humans as "the most likely vector, given the extensive data that we have about our history of exploration..." Especially if humans start visiting these temperate radiation-protected sites...

ZDNet asks the million-dollar question. "Despite the potential for vast productivity gains from generative AI tools such as ChatGPT or GitHub Copilot, will technology professionals' jobs actually grow more complicated? " People can now pump out code on demand in an abundance of languages, from Java to Python, along with helpful recommendations. Already, 95% of developers in a recent survey from Sourcegraph report they use Copilot, ChatGPT, and other gen AI tools this way. But auto-generating new code only addresses part of the problem in enterprises that already maintain unwieldy codebases, and require high levels of cohesion, accountability, and security. For starters, security and quality assurance tasks associated with software jobs aren't going to go away anytime soon. "For programmers and software engineers, ChatGPT and other large language models help create code in almost any language," says Andy Thurai, analyst with Constellation Research, before talking about security concerns. "However, most of the code that is generated is security-vulnerable and might not pass enterprise-grade code. So, while AI can help accelerate coding, care should be taken to analyze the code, find vulnerabilities, and fix it, which would take away some of the productivity increase that AI vendors tout about." Then there's code sprawl. An analogy to the rollout of generative AI in coding is the introduction of cloud computing, which seemed to simplify application acquisition when first rolled out, and now means a tangle of services to be managed. The relative ease of generating code via AI will contribute to an ever-expanding codebase — what the Sourcegraph survey authors refer to as "Big Code". A majority of the 500 developers in the survey are concerned about managing all this new code, along with code sprawl, and its contribution to technical debt. Even before generative AI, close to eight in 10 say their codebase grew five times over the last three years, and a similar number struggle with understanding existing code generated by others. So, the productivity prospects for generative AI in programming are a mixed bag.

The Associated Press reports: Tracking someone through apps and devices like the popular Apple AirTag without their consent could soon be deemed a criminal offense in Ohio, after the state's Republican-led Senate advanced the measure Wednesday with a unanimous bipartisan vote... [V]iolators could be charged with a new first-degree misdemeanor offense of the "illegal use of a device or application," resulting in up to 180 days in jail. If the individual holds a prior conviction of menacing by stalking, the charge could escalate to a fourth-degree felony, resulting in six to 18 months in jail... There is no known opposition to the measure. Exceptions to the proposal include some law enforcement activity; parents or guardians tracking their children; caregivers tracking an elderly or disabled person they are entrusted with; a non-private investigator acting on behalf of a "legitimate business purpose;" and private investigators on certain cases. The bill now heads to Ohio's House of Representatives for further consideration.

This week venture capitalist Marc Andreessen published "his views on AI, the risks it poses and the regulation he believes it requires," reports CNBC. But they add that "In trying to counteract all the recent talk of 'AI doomerism,' he presents what could be seen as an overly idealistic perspective of the implications..." Though he starts off reminding readers that AI "doesn't want to kill you, because it's not alive... AI is a machine — it's not going to come alive any more than your toaster will." Andreessen writes that there's a "wall of fear-mongering and doomerism" in the AI world right now. Without naming names, he's likely referring to claims from high-profile tech leaders that the technology poses an existential threat to humanity... Tech CEOs are motivated to promote such doomsday views because they "stand to make more money if regulatory barriers are erected that form a cartel of government-blessed AI vendors protected from new startup and open source competition," Andreessen wrote... Andreessen claims AI could be "a way to make everything we care about better." He argues that AI has huge potential for productivity, scientific breakthroughs, creative arts and reducing wartime death rates. "Anything that people do with their natural intelligence today can be done much better with AI," he wrote. "And we will be able to take on new challenges that have been impossible to tackle without AI, from curing all diseases to achieving interstellar travel...." He also promotes reverting to the tech industry's "move fast and break things" approach of yesteryear, writing that both big AI companies and startups "should be allowed to build AI as fast and aggressively as they can" and that the tech "will accelerate very quickly from here — if we let it...." Andreessen says there's work to be done. He encourages the controversial use of AI itself to protect people against AI bias and harms... In Andreessen's own idealist future, "every child will have an AI tutor that is infinitely patient, infinitely compassionate, infinitely knowledgeable, infinitely helpful." He expresses similar visions for AI's role as a partner and collaborator for every person, scientist, teacher, CEO, government leader and even military commander. Near the end of his post, Andreessen points out what he calls "the actual risk of not pursuing AI with maximum force and speed." That risk, he says, is China, which is developing AI quickly and with highly concerning authoritarian applications... To head off the spread of China's AI influence, Andreessen writes, "We should drive AI into our economy and society as fast and hard as we possibly can." CNBC also points out that Andreessen himself "wants to make money on the AI revolution, and is investing in startups with that goal in mind." But Andreessen's sentiments are clear. "Rather than allowing ungrounded panics around killer AI, 'harmful' AI, job-destroying AI, and inequality-generating AI to put us on our back feet, we in the United States and the West should lean into AI as hard as we possibly can."
