An anonymous reader quotes a report from Bloomberg: Italy is in advanced talks with Elon Musk's SpaceX for a deal to provide secure telecommunications for the nation's government -- the largest such project in Europe, people with knowledge of the matter said Sunday. Discussions are ongoing, and a final agreement on the five-year contract hasn't been reached, said the people, who asked not to be identified citing confidential discussions. The project has already been approved by Italy's Intelligence Services as well as Italy's Defense Ministry, they said. Italy on Monday confirmed discussions are ongoing, saying no deal had yet been reached. "The talks with SpaceX are part of normal government business," the government said.

The negotiations, which had stalled until recently, appeared to move forward after Italian Prime Minister Giorgia Meloni visited President-elect Donald Trump in Florida on Saturday. The Italian government said the two didn't discuss the issue during their meeting. Italian officials have been negotiating on a $1.6 billion deal aimed at supplying Italy with a full range of top-level encryption for telephone and Internet services used by the government, the people said. The plan also includes communications services for the Italian military in the Mediterranean area as well as the rollout of so-called direct-to-cell satellite services in Italy for use in emergencies like terror attacks or natural disasters, they said. The possible deal has been under review since mid-2023. It's been opposed by some Italian officials concerned about how the services may detract from local carriers.

NASA's Jet Propulsion Laboratory (JPL), located at the base of the San Gabriel Mountains just north of Los Angeles, has been temporarily shuttered due to the nearby Eaton fire. "JPL is closed except for emergency personnel. No fire damage so far (some wind damage) but it is very close to the lab. Hundreds of JPLers have been evacuated from their homes & many have lost homes. Special thx to our emergency crews. Pls keep us in your thoughts & stay safe," JPL Director Laurie Leshin announced via X today (Jan. 8). Space.com reports: JPL is federally funded but managed by the California Institute of Technology in Pasadena. The center runs many of NASA's high-profile robotic missions, such as the Perseverance and Curiosity Mars rovers and the $5 billion Europa Clipper, which recently launched to explore an intriguing ocean moon of Jupiter.

The Eaton fire sparked up on Tuesday evening (Jan. 7) near Altadena, which is just north of Pasadena. It has burned at least 1,000 acres (400 hectares) to date, according to CBS News, which cited the California Department of Forestry and Fire Protection (CalFire). The Eaton fire is one of several big blazes churning through the Los Angeles area, driven and spread by record-setting winds. The biggest and most destructive is the Palisades Fire, which is laying waste to the Pacific Palisades neighborhood on the west side of the city.

The Japanese government published an alert on Wednesday accusing a Chinese hacking group of targeting and breaching dozens of government organizations, companies, and individuals in the country since 2019. From a report: Japan's National Police Agency and the National Center of Incident Readiness and Strategy for Cybersecurity attributed the years-long hacking spree to a group called MirrorFace.

"The MirrorFace attack campaign is an organized cyber attack suspected to be linked to China, with the primary objective of stealing information related to Japan's national security and advanced technology," the authorities wrote in the alert, according to a machine translation. A longer version of the alert said the targets included Japan's Foreign and Defense ministries, the country's space agency, as well as politicians, journalists, private companies and tech think tanks, according to the Associated Press. In July 2024 Japan's Computer Emergency Response Team Coordination Center (JPCERT/CC) wrote in a blog post that MirrorFace's "targets were initially media, political organisations, think tanks and universities, but it has shifted to manufacturers and research institutions since 2023."

Scientists have discovered that quarks and gluons inside protons are quantum entangled, challenging traditional views of proton structure and revealing a more complex, dynamic system influenced by strong interactions. Space.com reports: Entanglement is the aspect of quantum physics that says two affected particles can instantaneously influence each other's "state" no matter how widely separated they are -- even if they are on opposite sides of the universe. Albert Einstein founded his theories of relativity on the notion that nothing can travel faster than the speed of light, however, something that should preclude the instantaneous nature of entanglement.

As a result, Einstein was so troubled by entanglement he famously described it as "spukhafte Fernwirkung" or "spooky action at a distance." Yet, despite Einstein's skepticism about entanglement, this "spooky" phenomenon has been verified over and over again. Many of those verifications have concerned testing increasing distances over which entanglement can be demonstrated. This new test took the opposite approach, investigating entanglement over a distance of just one quadrillionth of a meter, finding it actually occurs within individual protons.

The team found that the sharing of information that defines entanglement occurs across whole groups of fundamental particles called quarks and gluons within a proton. "Before we did this work, no one had looked at entanglement inside of a proton in experimental high-energy collision data," team member and Brookhaven Lab physicist Zhoudunming Tu said in a statement. "For decades, we've had a traditional view of the proton as a collection of quarks and gluons, and we've been focused on understanding so-called single-particle properties, including how quarks and gluons are distributed inside the proton. "Now, with evidence that quarks and gluons are entangled, this picture has changed. We have a much more complicated, dynamic system." The team's research, the culmination of six years of work, refines scientists' understanding of how entanglement influences the structure of protons. The team's research was published in the journal Reports on Progress in Physics.

An anonymous reader quotes a report from Wired: Laptop screens can feel cramped. But what if you could magically get more real estate without having to carry around a portable monitor? That's precisely the purpose of Lenovo's ThinkBook Plus Gen 6 Rollable AI PC -- yes, rollable. It has an OLED display that, with the push of a button, extends the 14-inch screen upward to make for an awkward aspect ratio, but roughly doubles the screen space to 16.7 inches. Two screens are better than one for productivity, but what if one screen could be two but still one? Yes.

It plays a fun animation and some music when it does its rolling thing. You can also activate the rolling action with a palm gesture; once it scans your palm, shift it up or down to raise or lower the screen. (Pressing the button on the keyboard is way faster.) You can take advantage of Windows 11 window snapping features to put apps one on top of the other. I stacked two browser windows, but you can put other apps below too. Considering I'm already that guy who brings a spare portable monitor everywhere, this just seems like a more elegant solution that takes up less space in my bag. And of course, anyone can take advantage of the long aspect ratio to get a better look at documents, PDFs, and web pages.

Lenovo says it has tested the rolling function 30,000 times, and it has performed without flaws, so you can rest a little easier about reliability, though repairing this machine sounds like it will be a task. The whole laptop doesn't feel significantly different from a normal machine, weighing just 3.7 pounds -- that's 1 pound less than the 16-inch MacBook Pro. However, walking with your laptop open in your hand might be weird, as it feels a little top heavy. When closed, it's 19.9 mm thin -- the 16-inch MacBook Pro is 15.4 mm, so Lenovo's machine is thicker, but not as thick as a gaming laptop. Lenovo published a concept video on YouTube.

Before NASA Administrator Bill Nelson retires in a couple of weeks, he has one final message for the next administration: Don't give up on the agency's Artemis Program to return humans to the Moon. In an interview with Ars Technica's Eric Berger, Nelson discussed his time in office, the major decisions he made, and his concerns for the space agency's future under the Trump administration. Here's an excerpt from the interview: Ars: I wanted to start with the state of Artemis. You all had an event a few weeks ago where you talked about Artemis II and Artemis III delays. And you know, both those missions have slipped a couple of years now since you've been administrator. So I'm just wondering, do you know how confident we should be in the current timeline?

Bill Nelson: Well, I am very confident because this most recent [delay] was occasioned by virtue of the heat shield, and it has been unanimous after all of the testing that they understand what happened to Orion's heat shield. The chunks came off in an irregular pattern from the Artemis I heat shield. With the change in the re-entry profile, they are unanimous in their recommendation that we can go with the Artemis II heat shield as it is. And I must say that of the major decisions that I've made, that was an easy one for me because it was unanimous. When I say it was unanimous, it was unanimous in the IRT, the independent review team, headed by Paul Hill. It wasn't to begin with, but after all the extensive testing, everybody was on board. It was unanimous in the deputy's committee. It was unanimous in the agency committee, and that brought it to me then in the Executive Council, and it was unanimous there. So I'm very confident that you're going to see Artemis II fly on or around April of 2026, and then if the SpaceX lander is ready, and that, of course, is a big if -- but they have met all of their milestones, and we'll see what happens on this next test... If they are ready, I think it is very probable that we will see the lunar landing in the summer of 2027.

Ars: Do you think it's appropriate for the next administration to review the Artemis Program?

Bill Nelson: Are you implying that Artemis should be canceled?

Ars: No. I don't think Artemis will be canceled in the main. But I do think they're going to take a look at the way the missions are done at the architecture. I know NASA just went through that process with Orion's heat shield.

Bill Nelson: Well, I think questioning what you're doing clearly is always an issue that ought to be on the table. But do I think that they are going to cancel, as some of the chatter out there suggests, and replace SLS with Starship? The answer is no.

Ars: Why?

Bill Nelson: Put yourself in the place of President Trump. Do you think President Trump would like to have a conversation with American astronauts on the surface of the Moon during his tenure?

Ars: Of course.

Bill Nelson: OK, let me ask you another question. Do you think that President Trump would rather have a conversation with American astronauts during his tenure rather than listening to the comments of Chinese astronauts on the Moon during his tenure? My case is closed, your Honor, I submit it to the jury. Further reading: Elon Musk: 'We're Going Straight to Mars. The Moon is a Distraction.'

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.

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.

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."

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."

"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."

"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."

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 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.

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."

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.

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 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.

In a press release today, Apple said their TV Plus subscription service will be free this weekend (January 3 through January 5). From the press release: Apple TV+ is ringing in the New Year by offering an all-access pass to customers all around the world. Enjoy Apple TV+ for free the first weekend of 2025 (January 3 through January 5), Apple TV+ will be free on any device where Apple TV+ is available. All you need is an Apple ID to see what all the buzz is about. "A full weekend may be enough to binge some of Apple's top shows, including Severance, which has its hotly anticipated season 2 launching on January 17th," notes The Verge's Umar Shakir. "The free days could also help potential subscribers get a taste of Apple's eclectic mix of sci-fi shows, such as the space race drama For All Mankind, postapocalyptic thriller Silo, and the Godzilla serial Monarch: Legacy of Monsters."

"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."
