Intel Says New Laptop Chips Will Extend Computer Battery Life (yahoo.com) 29

Intel, which has been fending off mounting competition in notebook processors, says a new range of chips will help enable the longest battery life available in laptops. From a report: New computers based on the latest version of its Core Ultra processors will go on sale starting this month, the company said Monday at CES, an annual consumer electronics show.

Intel was for decades the world's largest chipmaker thanks to its dominance of the computer processor market. Production technology stumbles and slow product introductions have opened the door to both long-time rivals and firms just entering the space. The company's board last month ousted its chief executive officer, citing the need to improve its offerings.

The new chips, intended for corporate PCs and high-end consumer devices, are aimed at boosting performance in two areas the company considers key selling points: battery life and the ability to run artificial intelligence functions. According to Intel, an HP laptop that uses one of the new processors can run Microsoft's Teams software for as long as 10.5 hours on a single charge. It can go 20.3 hours between charges when the user is running Microsoft's cloud-based 365 suite, Intel added. By comparison, Intel says a Dell device using a Qualcomm Snapdragon processor can last as long as 9.2 hours and 18.5 hours, respectively, under those conditions.

Disney To Merge Hulu + Live TV With Fubo (hollywoodreporter.com) 38

The Walt Disney Co. will merge its streaming multichannel video service Hulu with Live TV with its competitor Fubo in a surprise deal that will shake up the streaming TV business, the companies said Monday. From a report: The new company will continue to be traded publicly under the Fubo name, however Disney will control 70% and appoint a majority of the board. Fubo management, including co-founder and CEO David Gandler, will run the combined venture.

The deal will do a couple of big things if and when it is completed: For starters, it will create a much bigger player in the virtual multichannel video provider (vMVPD) space, one that can more aggressively take on the market leader YouTube TV. YouTube TV said a year ago that it had 8 million subscribers, while Hulu + Live TV had 4.6 million subscribers and Fubo had 1.6 million subscribers, giving a combined offering 6.2 million subs.

Jimmy Carter Remembered Fondly by Bill Gates, Environmentalists (gatesnotes.com) 75

As America begins a six-day state funeral for former president Jimmy Carter, Microsoft co-founder/philanthropist Bill Gates shared "my fondest memory" this week. "He and Rosalynn were among my first and most inspiring role models in global health." They played a pretty profound role in the early days of the Gates Foundation. I'm especially grateful that they introduced us to Dr. Bill Foege, who once helped eradicate smallpox and was a key advisor for our global health work.

Jimmy and Rosalynn were also good friends to my dad. One of my favorite photographs of all time shows Jimmy Carter, Nelson Mandela, and my dad in South Africa holding babies at a medical clinic. I remember my dad coming back from that trip with a whole new appreciation for Jimmy's passion for helping people with HIV. At the time, then-President Thabo Mbeki was refusing to let people with HIV get treatment, and my dad watched Jimmy almost get into a fist fight with Mbeki over the issue. As Jimmy said in a 2012 conversation at the Gates Foundation hosted by my dad, "He was claiming there was no relationship between HIV and AIDS and that the medicines that we were sending in, the antiretroviral medicines, were a white person's plot to help kill black babies." At a time when a quarter of all people in South Africa were HIV positive, Jimmy just couldn't accept Mbeki's obstructionism.

Ars Technica reported it was also Jimmy Carter who saved America's space shuttle program.

And Carter installed solar panels on the roof of the White House (which "were later removed by his successor, Ronald Reagan," according to Boiling Point, an environmental newsletter from the Los Angeles Times): He tried and largely failed to block construction of more than a dozen expensive, environmentally destructive water infrastructure projects such as dams, canals and reservoirs. He also tried to reduce U.S. dependence on foreign oil, implementing the first vehicle fuel-efficiency standards and tasking researchers with bringing down the cost of solar panels — an effort he predicted could be "a small part of one of the greatest and most exciting adventures ever undertaken by the American people...." And although he was largely thinking about how to free Americans from geopolitical crises that could wreak havoc on oil supplies and gasoline prices, he also had heat-trapping greenhouse gases in mind... The final report from the White House Council on Environmental Quality warned that fossil fuel combustion could cause "widespread and pervasive changes in global climatic, economic, social, and agricultural patterns." It advised that to avoid such risks, we should limit global temperature increases to 2 degrees Celsius above preindustrial levels — the goal eventually agreed to by nearly 200 nations, 35 years later.

Even if Carter's actions were targeted more at reducing oil imports than at cutting planet-warming pollution — he was willing to increase domestic coal production if it meant less dependence on foreign crude — the political battles he fought, particularly those he lost, have lessons for those of us who care about the climate today. The historian Kai Bird, for instance, notes that after struggling to pass a tax on gas-guzzling cars, Carter wrote in his diary, "The influence of the oil and gas industry is unbelievable, and it's impossible to arouse the public to protect themselves." Indeed, oil and gas companies still wield huge influence. SUVs are more popular than ever.

The newsletter argues the story of Carter's life can be an inspiration, since Carter saw a lot of changes in his 100 years.

"We need to see more changes to survive. May we all be as lucky as Carter was."

New York Times Recognizes Open-Source Maintainers With 2024 'Good Tech' Award (thestar.com.my) 7

This week New York Times technology columnist Kevin Roose published his annual "Good Tech" awards to "shine the spotlight on a few tech projects that I think contributed positively to humanity."

And high on the list is "Andres Freund, and every open-source software maintainer saving us from doom." The most fun column I wrote this past year was about a Microsoft database engineer, Andres Freund, who got some odd errors while doing routine maintenance on an obscure open-source software package called xz Utils. While investigating, Freund inadvertently discovered a huge security vulnerability in the Linux operating system, which could have allowed a hacker to take control of hundreds of millions of computers and bring the world to its knees.

It turns out that much of our digital infrastructure rests on similar acts of nerdy heroism. After writing about Freund's discovery, I received tips about other near disasters involving open-source software projects, many of which were averted by sharp-eyed volunteers catching bugs and fixing critical code just in time to foil the bad guys. I could not write about them all, but this award is to say: I see you, open-source maintainers, and I thank you for your service.

Roose also acknowledges the NASA engineers who kept Voyager 1 transmitting back to earth from interstellar space — and Bluesky, "for making my social media feeds interesting again."

Roose also notes it was a big year for AI. There's a shout-out to Epoch AI, a small nonprofit research group in Spain, "for giving us reliable data on the AI boom." ("The firm maintains public databases of AI models and AI hardware, and publishes research on AI trends, including an influential report last year about whether AI models can continue to grow at their current pace. Epoch AI concluded they most likely could until 2030.") And there's also a shout-out to groups "pushing AI forward" and positive uses "to improve health care, identify new drugs and treatments for debilitating diseases and accelerate important scientific research."
  • The nonprofit Arc Institute released Evo, an AI model that "can predict and generate genomic sequences, using technology similar to the kind that allows systems like ChatGPT to predict the next words in a sequence."
  • A Harvard University lab led by Dr. Jeffrey Lichtman teamed with researchers from Google for "the most detailed map of a human brain sample ever created. The team used AI to map more than 150 million synapses in a tiny sample of brain tissue at nanometer-level resolution..."
  • Researchers at Stanford and McMaster universities developed SyntheMol, "a generative AI model that can design new antibiotics from scratch."

Elon Musk: 'We're Going Straight to Mars. The Moon is a Distraction.' (arstechnica.com) 278

"We're going straight to Mars. The Moon is a distraction," Elon Musk posted Thursday on X.com.

Ars Technica's senior space editor points out that "These are definitive statements that directly contradict NASA's plans to send a series of human missions to the lunar south pole later this decade and establish a sustainable base of operations there with the Artemis Program." And "It would be one thing if Musk was just expressing his opinion as a private citizen..." but Musk "has assumed an important advisory role for the incoming administration. He was also partly responsible for the expected nomination of private astronaut [and former SpaceX flight commander] Jared Isaacman to become the next administrator of NASA. Although Musk is not directing US space policy, he certainly has a meaningful say in what happens." So what does this mean for Artemis? The fate of Artemis is an important question not just for NASA but for the US commercial space industry, the European Space Agency, and other international partners who have aligned with the return of humans to the Moon. With Artemis, the United States is in competition with China to establish a meaningful presence on the surface of the Moon. Based upon conversations with people involved in developing space policy for the Trump administration, I can make some educated guesses about how to interpret Musk's comments. None of these people, for example, would disagree with Musk's assertion that "the Artemis architecture is extremely inefficient" and that some changes are warranted.

With that said, the Artemis Program is probably not going away. After all, it was the first Trump administration that created the program about five years ago. However, it may be less well-remembered that the first Trump White House pushed for more significant changes, including a "major course correction" at NASA... To a large extent, NASA resisted this change during the remainder of the Trump administration, keeping its core group of major contractors, such as Boeing and Lockheed Martin, in place. It had help from key US Senators, including Richard Shelby, the now-retired Republican from Alabama. But this time, the push for change is likely to be more concerted, especially with key elements of NASA's architecture, including the Space Launch System rocket, being bypassed by privately developed rockets such as SpaceX's Starship vehicle and Blue Origin's New Glenn rocket.

In all likelihood, NASA will adopt a new "Artemis" plan that involves initiatives to both the Moon and Mars. When Musk said "we're going straight to Mars," he may have meant that this will be the thrust of SpaceX, with support from NASA. That does not preclude a separate initiative, possibly led by Blue Origin with help from NASA, to develop lunar return plans.

One month ago in a post on X.com, incoming NASA administrator Isaacman described himself as "passionate about America leading the most incredible adventure in human history..."

And he also added that Americans "will walk on the Moon and Mars and in doing so, we will make life better here on Earth."

Billionaires and Tech Barons Vying To Build a Private Space Station (telegraph.co.uk) 61

"Private space stations have been raising billions of dollars in an effort to build future hubs — and even one day cities — in orbit," according to a recent report from the U.K. newspaper, the Telegraph: Axiom Space, a US business aiming to build its own station, has raised more than $500m (£400m). Vast, a space business backed by crypto billionaire Jed McCaleb, is plotting two stations before the end of the decade. Gravitics, meanwhile, has raised tens of millions of dollars for its modular space "real estate". Nasa itself, along with other space agencies, is planning a further station, Lunar Gateway, which will orbit the Moon. Jeff Bezos's Blue Origin has also announced plans to build a space station by 2027, called Orbital Reef, which it has described as an orbital "mixed-use business park". Working with US aerospace business Sierra Space, Orbital Reef will be made up of inflatable pods, which can be launched on a regular rocket before being "blown up" in space. Sierra Space says these modules could house in-space manufacturing or pharmaceutical technology...

Since 2021, Nasa has also offered to pay hundreds of millions of dollars to private companies to develop commercial space stations that could succeed the ISS. So far, it has handed $400m to companies including Axiom, Blue Origin (which is working with Sierra Space), and Northrop Grumman... Vast hopes to launch its first space station, Haven-1, as soon as 2025. This simple module will be the first privately-run space station and will be occupied by a crew of four over four two week expeditions... While Vast was not one of the businesses to secure funding from Nasa, it hopes by launching the first proof-of-concept space station as soon as next year it can leapfrog rival efforts and claim the agency as an anchor customer. From there, it can target other space agencies or companies looking to conduct research.

Some interesting perspectives from the article:
  • Chris Quilty, an analyst at Quilty Space: "If China were not building its own space station it is arguable whether Nasa would have felt enjoined to maintain a human presence in low Earth orbit."
  • Tim Farrar, founder of TMF Associates, which advises some of the world's top space companies: "Unless they either secure government funding or focus on space tourism, they will inevitably have to rely on the largess of either billionaires or gullible investors who are space enthusiasts."

'Starlink Mini': High-Speed Internet, Fits in a Backpack, Now Available in the US (cnet.com) 74

It's weighs less than 15 pounds. It's 17 inches wide. And in June Elon Musk said it was "easily carried in a backpack. This product will change the world."

And now, CNET reports: Calling all digital nomads and van-lifers: SpaceX's Starlink Mini is now available everywhere in the US. The small antenna costs $599 and requires a monthly subscription of either $50 or $165, depending on which plan you choose. Thanks to thousands of low Earth orbit satellites, Starlink has the unique ability to send high-speed internet just about anywhere. Standard service is great for home internet in rural areas, while the provider's Roam service and new portable dish are ideal for staying connected on the go...

The Mini is a satellite dish and Wi-Fi router all in one that's about the size of a laptop. According to Starlink's website, it uses approximately half the power of Starlink's standard dish. It can be powered with a portable USB battery and can "melt snow and withstand sleet, heavy rain and harsh winds."

The article adds that users "can connect up to 128 devices, and it promises low latency... According to Starlink's broadband labels, your download speeds typically range from 30 to 100Mbps and 5 to 25Mbps in upload."

Apple Intelligence Now Requires Nearly Double the iPhone Storage 44

Apple Intelligence now requires 7GB of free storage per device, nearly doubling the original 4GB requirement from iOS 18.1. This is a result of new AI features like Genmoji, ChatGPT in Siri, and Image Playground. With further updates expected, storage demands could rise to 10GB per device. 9to5Mac reports: Per Apple's website, Apple Intelligence now requires 7GB of free storage. The same 7GB number applies whether you're using an iPhone, iPad, or Mac. But it also, since each product does its own on-device processing, adds up for multi-device use. If you want to use AI features across all three devices (which I'd assume most of us do), that's a grand total of 21GB of free space being used by Apple Intelligence. And unfortunately, if you're tight on storage, there's no way to reduce the requirement by disabling certain features.

New 'All-Optical' Nanoscale Sensors of Force Access Previously Unreachable Environments (phys.org) 8

ZipNada shares a report from Phys.org: In a paper published today in Nature, a team led by Columbia Engineering researchers and collaborators report that they have invented new nanoscale sensors of force. They are luminescent nanocrystals that can change intensity and/or color when you push or pull on them. These "all-optical" nanosensors are probed with light only and therefore allow for fully remote read-outs -- no wires or connections are needed. They have 100 times better force sensitivity than the existing nanoparticles that utilize rare-earth ions for their optical response, and an operational range that spans more than four orders of magnitude in force, a much larger range -- 10-100 times larger -- than any previous optical nanosensor. "We expect our discovery will revolutionize the sensitivities and dynamic range achievable with optical force sensors, and will immediately disrupt technologies in areas from robotics to cellular biophysics and medicine to space travel," said Jim Schuck, associate professor of mechanical engineering.

"The importance of developing new force sensors was recently underscored by Ardem Patapoutian, the 2021 Nobel Laureate who emphasized the difficulty in probing environmentally sensitive processes within multiscale systems -- that is to say, in most physical and biological processes," Schuck notes. "We are excited to be part of these discoveries that transform the paradigm of sensing, allowing one to sensitively and dynamically map critical changes in forces and pressures in real-world environments that are currently unreachable with today's technologies."

Scientists Pin Down the Origins of a Fast Radio Burst 17

MIT scientists have pinpointed the origin of a fast radio burst (FRB) to within 10,000 kilometers of a neutron star, settling a long-standing debate about these cosmic phenomena. Using a novel technique analyzing signal scintillation, researchers determined that FRB 20221022A, detected in 2022 from a galaxy 200 million light-years away, emerged from the star's turbulent magnetosphere rather than from a distant shockwave.

The findings, published in Nature, provide the first conclusive evidence that FRBs can originate in the extreme magnetic environment immediately surrounding these ultra-compact objects.

NATO Plans To Build Satellite Links As Backups To Undersea Cables (tomshardware.com) 65

Tom's Hardware reports that NATO is developing an advanced system to address the growing number of undersea cable disruptions observed in recent years. Known as HEIST (Hybrid Space-Submarine Architecture Ensuring Infosec of Telecommunications), the project is designed to significantly enhance the resilience of undersea communication networks. HEIST will enable damage detection with an accuracy of one meter, facilitate rapid data rerouting through satellite networks when disruptions occur, and establish open-source protocols to foster global collaboration. From the report: Satellites are the primary backups to undersea cables, but their bandwidth is far behind physical connections. For example, Google's latest fiber-optic lines can hit 340 terabits per second. In contrast, the frequency used by most satellites -- 12 to 18GHz -- can only handle about 5 gigabits per second or about 0.0015% of the maximum throughput of Google's fiber connection.

Work is underway to upgrade satellites from radio transmissions to lasers, increasing the speed by about 40 times to 200 Gbps. Starlink already uses this technology to communicate between its satellites, while Amazon is also developing it for its own Project Kuiper. However, it still faces challenges, like poor visibility and targeting precision between the satellite and ground station.

Because this is a major NATO project, the alliance plans to open-source part of the process. Making it public would allow anyone interested to find holes and make many iterations. Gregory Falco, the NATO Country Director for HEIST, believes that this is the fastest way for the project to achieve its goals and help prevent any catastrophic loss of data transmission in case of deliberate attacks against these underwater infrastructures in international waters.

Astronomers Discover an Ultra-Massive Grand-Design Spiral Galaxy (phys.org) 23

Astronomers using the James Webb Space Telescope have discovered Zhulong, the most distant grand-design spiral galaxy identified so far, located at a redshift of approximately 5.2. Phys.Org reports: The galaxy was named Zhulong, after a giant red solar dragon and god in Chinese mythology. [...] Its mass was found to be comparable to that of the Milky Way, which is relatively high for a galaxy that formed within one billion years after the Big Bang, as the redshift indicates. The study found that Zhulong has a classical bulge and a large face-on stellar disk with spiral arms extending across 62,000 light years. The spectral energy distribution (SED) analysis points to a quiescent-like core and a star-forming stellar disk. Furthermore, it turned out that compared to the stellar disk, the center core of Zhulong is red and has the highest stellar mass surface densities measured among quiescent galaxies. The core is quiescent, which is consistent with the expectations of inside-out galaxy growth and quenching.

The study also found that although the disk is still forming stars, Zhulong has a relatively low overall star-formation rate -- at a level of 66 solar masses per year. The baryons-to-stars conversion efficiency was calculated to be approximately 0.3, which is about 1.5 times higher than even the most efficient galaxies at later epochs. These results suggest that Zhulong must have been forming stars very efficiently and is in the transformation phase from star-forming to quiescence. In concluding remarks, the authors of the paper note that Zhulong appears to be the most distant spiral galaxy discovered to date. The properties of this galaxy seem to suggest that mature galaxies emerged much earlier than expected in the first billion years after the Big Bang.
The findings have been published on the pre-print server arXiv.

How Microsoft Made 2024 the Year of Windows on Arm (theverge.com) 58

"I still can't quite believe that I'm using an Arm-powered Windows laptop every day," writes a senior editor at the Verge: After more than a decade of trying to make Windows on Arm a reality, Microsoft and Qualcomm finally nailed it this year with Copilot Plus PCs. These new laptops have excellent battery life and great performance — and the app compatibility issues that have plagued Windows on Arm are mostly a thing of the past (as long as you're not a gamer). Microsoft wanted 2024 to be "the year of the AI PC," but I think it was very much the year of Windows on Arm...

The key to Windows on Arm's revival this year was Qualcomm's Snapdragon X Elite processors, which were announced in April. They've provided the type of performance and power efficiency only previously available with Apple's MacBooks and challenged Intel and AMD to do better in the x86 space. After much debate over Microsoft's MacBook Air-beating benchmarks, the reviews rolled in and showed that Windows on Arm was indeed capable of matching and beating Apple's MacBook Air. Qualcomm even hired the "I'm a Mac" guy to promote Windows on Arm PCs, showing how confident it was in challenging Apple's laptop dominance.

Microsoft and Qualcomm also worked closely with developers to make key apps compatible, and it's now very rare to run into an app compatibility issue that can't be solved by a native Arm64 version or Microsoft's improved emulator. Even Google, which previously shunned Windows Phone, has created Arm64 versions of Chrome and Google Drive to support Microsoft's efforts. With developers continually providing native versions of their apps, it makes it a lot easier to switch to a Windows on Arm laptop. The only big exception is gaming, where x86 still reigns supreme for compatibility and performance...

It's hard not to see 2025 as the year that Windows on Arm continues to eat into the laptop space. A Dell leak revealed Qualcomm is preparing new chips for 2025, and the chip maker has also been rolling out cheaper Arm-based chips to bring laptop prices down.

The article acknowledges that both AMD and Intel "have the key advantage of game compatibility that Windows on Arm is definitely not ready for..." But "Given the Windows on Arm gaming situation, a new generation of Nvidia's GPUs could help generate fresh excitement around x86 laptops throughout 2025." And "Nvidia might also be planning to help the Windows on Arm effort. The chip maker has long been rumored to be planning to launch Arm PC chips as soon as 2025... Whatever happens to laptops in 2025, you can guarantee that there's going to be fierce competition between Intel, AMD, and Qualcomm."

But the author still complains about the dedicated Copilot key on his new WIndows-on-Arm laptop. "While the Copilot experience on Windows has gone through several confusing revisions, it's still a key I accidentally press and then get frustrated when a Copilot window appears."

Can Money Buy You a Longer Life? (msn.com) 98

An anonymous reader shared this report from the Wall Street Journal: The rich get richer — and older. People with high salaries and net worth tend to live longer lives, research shows. Once Americans make it to their late 50s, the wealthiest 10% live to a median age of around 86 years, roughly 14 years longer than the least wealthy 10%, according to a study published earlier this year in JAMA Internal Medicine. People with more money can afford healthier food, more healthcare and homes in safer, less-polluted neighborhoods, says Kathryn Himmelstein, a co-author of the study and a medical director at the Boston Public Health Commission.

Though you can't add more months or years to your online shopping cart yet, health and aging researchers say there are ways to spend money to improve your chances of living longer. They suggest favoring purchases that help you track your health, stay active and reduce stress. "We know the things that help us age better, and everyone's always disappointed when you tell them," says Andrew Scott, director of economics at the Ellison Institute of Technology in Oxford, England. "Eat less and eat better, sleep more, exercise more and spend time with friends...." But certain gadgets and luxuries can be worth the cost, some researchers say. Devices such as the Apple Watch and Oura Ring can instill healthy habits and catch worrying patterns that might emerge between annual checkups, says Joe Coughlin, the director of the MIT AgeLab... Coughlin says he once went to the emergency room because his Apple Watch detected a spike in his heart rate that he hadn't noticed himself.

"For the superwealthy, suddenly living longer and living better has become the new prestige," Coughlin says. Higher incomes correlate with longer lives, but there are diminishing returns. Each successive jump in pay is linked to smaller boosts in longevity, a 2016 study from the research group Opportunity Insights found... A key to the relationship between income and longevity is that money doesn't just buy stuff that helps you live longer. It also buys time and reduces stress. "If you've got a nice place to live and you don't have to worry about food on the table, you have the mental head space and resources to prioritize your health," says Steven Woolf, a professor at Virginia Commonwealth University School of Medicine... Moreover, many lower-income jobs are more physically taxing and more prone to workplace accidents and exposure to harmful substances.

The article also includes examples of spending that promotes health, including things like home gym equipment and even swing-dancing lessons.

But it also adds that "plenty of things that are good for you don't come with a bill, such as going on a walk or minimizing screen time before bedtime."

Electric Air Taxis are Taking Flight. Can They Succeed as a Business? (msn.com) 43

An anonymous reader shared this report from the Washington Post: Archer is aiming to launch its first commercially operated [and electrically-powered] flights with a pilot and passengers within a year in Abu Dhabi. A competitor, Joby Aviation, says it is aiming to launch passenger service in Dubai as soon as late 2025. Advancements in batteries and other technologies required for the futuristic tilt-rotor craft are moving so fast that they could soon move beyond the novelty stage and into broader commercial use in a matter of years. Both companies are laying plans to operate at the 2028 Olympics in Los Angeles...

Scaling the industry from a novelty ride for the wealthy to a broadly available commuter option will take billions more in start-up money, executives said, including building out a network of takeoff and landing areas (called vertiports) and charging stations. Some high-profile ventures have already faltered. A plan for air taxis to transport spectators around the Paris Olympics fizzled... Still, investors, including big names like Stellantis and Toyota, have poured money into Silicon Valley companies like Archer and Joby. Boeing and Airbus are developing their own versions. All are betting that quieter, greener and battery-powered aircraft can revolutionize the way people travel. Major U.S. airlines including American, Delta, Southwest and United also are building relationships and planting seeds for deals with air taxi companies.

Two interesting quotes from the article:
  • "It feels like the modern-day American Dream, where you can invent a technology and actually bring it to market even [if it's] as crazy as what some people call flying cars."

    — Adam Goldstein, CEO of Archer Aviation.
  • "They have created these amazing new aircraft that really 10 or 15 years ago would've been unimaginable. I think there's something innately attractive about being able to leapfrog all of your terrestrial obstacles. Who hasn't wished that if you live in the suburbs that, you know, something could drop into your cul-de-sac and 15 minutes later you're at the office."

    — Roger Connor, curator of the vertical flight collection at the Smithsonian's National Air and Space Museum.

Will AI Transform Online Dating? (cnn.com) 158

"Dating apps are on the cusp of a major transformation," argues CNN, suggesting AI-powered possibilities like "personalized chatbots dating other chatbots on your behalf," as well as "AI concierges fielding questions about potential matches," and "advanced algorithms predicting compatibility better than ever before." At its investor day last week, executives from Match Group — the parent company of Match.com, Tinder, Hinge, OkCupid, Our Time and more — teased plans to use AI to improve user experiences and help make better connections. Justin McLeod, CEO of Hinge, outlined how the company intends to fully embrace AI next year: more personalized matching, smarter algorithms that adapt to users and better understand them over time and AI coaching for struggling daters. "While AI is not going to be a panacea when it comes to the very deeply and personal problem of love, I can tell you that it is going to transform the dating app experience, taking it from a do-it-yourself platform to an expertly guided journey that leads to far better outcomes and much better value to our daters," he told investors....

It's already starting to play a bigger role. Tinder, for example, uses AI to help users select their best profile photos. Meanwhile, Bumble's recently enhanced "For You" roundup uses advanced AI when delivering its daily set of four curated profiles based on a user's preferences and past matches. Bumble also uses AI in safety features like its Private Detector — an AI-powered tool that blurs explicit images — and Deception Detector, which identifies spam, scams and fake profiles. Similarly, Match Group offers tools like buttons that say "Are You Sure?" to detect harmful language and "Does This Bother You?" to prompt users to report inappropriate behavior....

According to Liesel Sharabi, an associate professor at Arizona State University's Hugh Downs School of Human Communication, the dating industry is still "very much in the early stages" of embracing AI. "The platforms are still figuring out its role in the online dating experience, but it really does have the potential to transform this space...." Bumble founder Whitney Wolfe Herd previously said she envisions AI functioning as a dating concierge, helping users navigate matches, set up dates and respond to messages. Startups such as Volar and Rizz have already experimented with chatbots that help respond to messages. On Rizz, users upload screenshots of conversations they're having on other dating apps, and the platform helps create flirty replies. (Volar, a standalone dating app that trains on users' preferences and automatically responds to other chatbots, shut down in September due to lack of funding.) While the concept of chatbots dating on your behalf may seem strange, it could reduce the tedious early-stage communication by focusing more on highly compatible matches, Sharabi said...

During Match Group's investor day, Hinge's McLeod announced plans to build the "world's most knowledgeable dating coach" using years of insights from the dating process... McLeod said Hinge has already seen a higher number of matches and subscription renewals with its improved AI algorithm among early test groups. It plans to roll this out globally in March.

And of course, some users are already using ChatGPT to write online dating profiles or respond to messages, the article points out...

LEAP 71 Hot-Fires Advanced Aerospike Rocket Engine Designed by AI (newatlas.com) 26

Long-time Slashdot reader schwit1 writes: The Dubai-based startup LEAP71, focused on using AI software to quickly develop rocket engine designs it can then 3D print, has successfully test fired a prototype aerospike engine on December 18, 2024 during a static fire test campaign conducted in the United Kingdom.
Along the way they tackled a problem with bell-shaped rocket nozzles, writes New Atlas. "A rocket that works very well on liftoff will work less well as it rises in the atmosphere and the air pressure decreases. This is why second- and third-stage rocket engines are different from those of the first stage." Ideally, engineers want an engine that can adjust itself automatically to changes in air pressure. An aerospike does this by shaping the engine into a spike or plug with a curve like that of the inside of a rocket bell. As the combustion gases flow from the engine over the spike, the curve acts as one side of the bell and the surrounding air as the outside curve. As the air pressure changes, so does the shape of the virtual bell. There have been a number of aerospike engines developed since the 1950s and one has actually gone airborne, but there's still a long way to go when it comes to turning a promising idea into a practical space engine.

LEAP 71's contribution to the effort is to apply its Noyron Large Computational Engineering Model to the problem. It's an AI programmed and trained by aerospace experts to take a given set of input parameters and use them to create a design that meets those parameters by inferring physical interactions of various factors, including thermal behaviors and projected performance. The results of this are then fed back into the AI model to fine tune it as it presents computed performance parameters, the geometry of the engine, the parameters of the manufacturing process, and other details.

"Despite their clear advantages, Aerospikes are not used in space access today," LEAP 71's co-founder said in a statement. "We want to change that. Noyron allows us to radically cut the time we need to re-engineer and iterate after a test and enables us to converge rapidly on an optimal design."

Aerospikes "are more compact and significantly more efficient across various atmospheric pressures, including the vacuum of space," the company said this week — announcing the successful hot-firing of their Aerospike engine, and calling it "one of the most advanced and elusive rocket engines ever created..." By leveraging the power of Noyron's computational AI, the thruster was developed in a matter of weeks, manufactured as a monolithic piece of copper through industrial 3D printing, and put on the test stand, where it worked successfully on the first attempt...

The Aerospike was fired on December 18th, 2024, as part of a four-engines-in-four-days campaign conducted by LEAPâ71 at Airborne Engineering in Westcott, UK. The company will process the collected data to fine-tune Noyron for the next iteration of engines and continue testing in 2025, with the goal of making Aerospikes a viable option for modern spacecraft.

'Universal Basic Income' Isn't a Silver Bullet, Says Lead Researcher on Sam Altman's Study (yahoo.com) 231

Business Insider reports: The lead researcher for Sam Altman's basic-income study says guaranteed no-strings payments are not a silver bullet for issues facing lower-income Americans. Elizabeth Rhodes, the research director for the Basic Income Project at Open Research, told Business Insider that while basic-income payments are "beneficial in many ways," the programs also have "clear limitations...."

Rhodes headed up one of the largest studies in the space, which focused specifically on those on low incomes rather than making universal payments to adults across all economic demographics. The three-year experiment, backed by OpenAI boss Altman, provided 1,000 low-income participants with $1,000 a month without any stipulations for how they could spend it.... The initial findings, released in July, found that recipients put the bulk of their extra spending toward basic needs such as rent, transportation, and food. They also worked less on average but remained engaged in the workforce and were more deliberate in their job searches compared with a control group. But Rhodes says the research reinforced how difficult it is to solve complex issues such as poverty or economic insecurity, and that there is "a lot more work to do."

The Altman-backed study is still reporting results. New findings released in December showed recipients valued work more after receiving the recurring monthly payments — a result that may challenge one of the main arguments against basic income payments. Participants also reported significant reductions in stress, mental distress, and food insecurity during the first year, though those effects faded by the second and third years of the program. "Poverty and economic insecurity are incredibly difficult problems to solve," Rhodes said. "The findings that we've had thus far are quite nuanced."

She added: "There's not a clear through line in terms of, this helps everyone, or this does that. It reinforced to me the idea that these are really difficult problems that, maybe, there isn't a singular solution."

In an earlier article coauthor David Broockman told Business Insider that the study's results might offer insights into how future programs could be successful — but said that the study's results didn't necessarily confirm the fears or hopes expressed by skeptics or supporters of a basic income.

NASA's Parker Solar Probe Completes Historic Christmas Eve Flyby of the Sun (livescience.com) 21

NASA's Parker Solar Probe made a historic approach on Christmas Eve, flying within 3.8 million miles of the Sun at a record-breaking speed of 430,000 mph. It marks humanity's closest encounter with a star. Live Science reports: Mission control cannot communicate with the probe during this rendezvous due to its vicinity to the sun, and will only know how the spacecraft fared in the early hours of Dec. 27 after a beacon signal confirms both the flyby's success and the overall state of the spacecraft. Images gathered during the flyby will beam home in early January, followed by scientific data later in the month when the probe swoops further away from the sun, Nour Rawafi, who is the project scientist for the mission, told reporters at the Annual Meeting of the American Geophysical Union (AGU) earlier this month.

Parker launched in 2018 to help decode some of the biggest mysteries about our sun, such as why its outermost layer, the corona, heats up as it moves further from the sun's surface, and what processes accelerate charged particles to near-light speeds. In addition to revolutionizing our understanding about the sun, the probe also caught rare closeups of passing comets and studied the surface of Venus. On Christmas Eve, scientists expect the probe to have flown through plumes of plasma still attached to the sun, and hope it observed solar flares occurring simultaneously due to ramped-up turbulence on the sun's surface, which spark breathtaking auroras on Earth but also disrupt communication systems and other technology.
"Right now, Parker Solar Probe has achieved what we designed the mission for," Nicola Fox, the associate administrator for NASA Science Mission Directorate at NASA Headquarters in Washington, D.C., said in a NASA video released on Dec. 24. "It's just a total 'Yay! We did it' moment."
