Microsoft is announcing some fairly major changes for Windows and the Surface lineup as part of its Build developer conference this week, but there’s one thing that’s definitely not coming, at least not right now: a Windows 12 update.

Speculation about the “Windows 12” update began propagating at some point last year in reports that suggested that Microsoft was shifting back to a three-year release cycle like the ones used for Windows Vista, 7, 8, and 10 in the late 2000s and early 2010s.

And Microsoft may have intended to call this fall’s release “Windows 12” at some point, and it does come with substantial changes both above and under the hood to better support Arm systems and to emphasize Microsoft’s AI focus.

Microsoft is using its new Surface launch and this week’s Build developer conference as a platform to launch its new “Copilot+" PC initiative, which comes with specific hardware requirements that systems will need to meet to be eligible. Copilot+ PCs will be able to handle some AI-accelerated workloads like chatbots and image generation locally instead of relying on the cloud, but new hardware will generally be required to run these workloads quickly and power efficiently.

At a minimum, systems will need 16GB of RAM and 256GB of storage, to accommodate both the memory requirements and the on-disk storage requirements needed for things like large language models (LLMs; even so-called “small language models” like Microsoft’s Phi-3, still use several billion parameters). Microsoft says that all of the Snapdragon X Plus and Elite-powered PCs being announced today will come with the Copilot+ features pre-installed, and that they'll begin shipping on June 18th.

But the biggest new requirement, and the blocker for virtually every Windows PC in use today, will be for an integrated neural processing unit, or NPU. Microsoft requires an NPU with performance rated at 40 trillion operations per second (TOPS), a high-level performance figure that Microsoft, Qualcomm, Apple, and others use for NPU performance comparisons. Right now, that requirement can only be met by a single chip in the Windows PC ecosystem, one that isn't even quite available yet: Qualcomm's Snapdragon X Elite and X Plus, launching in the new Surface and a number of PCs from the likes of Dell, Lenovo, HP, Asus, Acer, and other major PC OEMs in the next couple of months. All of those chips have NPUs capable of 45 TOPS, just a shade more than Microsoft's minimum requirement.

Microsoft is going all-in on Arm-powered Windows PCs today with the introduction of a Snapdragon X Elite-powered Surface Pro convertible and Surface Laptop, and there are inevitable comparisons to draw with another big company that recently shifted from Intel’s processors to Arm-based designs: Apple.

A huge part of the Apple Silicon transition’s success was Rosetta 2, a translation layer that makes it relatively seamless to run most Intel Mac apps on an Apple Silicon Mac with no extra effort required from the user or the app’s developer. Windows 11 has similar translation capabilities, and with the Windows 11 24H2 update, that app translation technology is getting a name: Prism.

Microsoft says that Prism isn’t just a new name for the same old translation technology. Translated apps should run between 10 and 20 percent faster on the same Arm hardware after installing the Windows 11 24H2 update, offering some trickle-down benefits that users of the handful of Arm-based Windows 11 PCs should notice even if they don’t shell out for new hardware. The company says that Prism's performance should be similar to Rosetta's, though obviously this depends on the speed of the hardware you're running it on.

Only about 15 percent of the electrode-bearing threads implanted in the brain of Neuralink's first human brain-chip patient continue to work properly, according to a report from The Wall Street Journal. The remaining 85 percent of the threads became displaced, and many of the threads that were left receiving little to no signals have been shut off.

In a May 8 blog post, Neuralink had disclosed that "a number" of the chip's 64 thinner-than-hair threads had retracted. Each thread carries multiple electrodes, totaling 1,024 across the threads, which are surgically implanted near neurons of interest to record signals that can be decoded into intended actions.

Neuralink was quick to note that it was able to adjust the algorithm used for decoding those neuronal signals to compensate for the lost electrode data. The adjustments were effective enough to regain and then exceed performance on at least one metric—the bits-per-second (BPS) rate used to measure how quickly and accurately a patient with an implant can control a computer cursor.

The Bureau of Land Management announced Thursday that it would no longer make federally managed lands in Wyoming’s Powder River Basin available for new coal mining leases, drawing condemnation from the fossil fuel industry in the region that produces the most coal in the country, but delivering a boon to the nation’s clean energy transition.

The Powder River Basin, a geological formation that covers much of northeast Wyoming and a portion of southeast Montana, has been the nation’s largest source of coal for decades, with production there peaking in 2008. Since then, demand for coal has plummeted, largely due to the rise of natural gas and renewable energy. Taking federal coal off the table in the basin could all but put an expiration date on the nation’s thermal coal industry.

OpenAI has paused a voice mode option for ChatGPT-4o, Sky, after backlash accusing the AI company of intentionally ripping off Scarlett Johansson's critically acclaimed voice-acting performance in the 2013 sci-fi film Her.

In a blog defending their casting decision for Sky, OpenAI went into great detail explaining its process for choosing the individual voice options for its chatbot. But ultimately, the company seemed pressed to admit that Sky's voice was just too similar to Johansson's to keep using it, at least for now.

"We believe that AI voices should not deliberately mimic a celebrity's distinctive voice—Sky’s voice is not an imitation of Scarlett Johansson but belongs to a different professional actress using her own natural speaking voice," OpenAI's blog said.

More than 60 years after he was denied an opportunity to become America's first Black astronaut, Ed Dwight finally traveled into space Sunday with five other passengers on a 10-minute flight inside a Blue Origin capsule.

Dwight, a retired Air Force captain and test pilot, had a chance to become the first African American astronaut. He was one of 26 pilots the Air Force recommended to NASA for the third class of astronauts in 1963, but the agency didn't select him. It took another 20 years for America's first Black astronaut, Guion Bluford, to fly in space in 1983.

“Everything they did, I did, and I did it well," Dwight said in a video released by Blue Origin. "If politics had changed, I would have gone to space in some kind of capacity.”

Later this week, the US federal agency charged with weather forecasting will release its outlook for the 2024 Atlantic hurricane season at a news conference in Washington, DC. But we already know what the National Oceanic and Atmospheric Administration (NOAA) forecast will say: This year will likely be extremely active in the Atlantic Ocean, Gulf of Mexico, and Caribbean Sea.

The Atlantic season formally begins on June 1, and based on current trends, the first named storm may not develop until the middle of the month or later. But make no mistake—when the light switches on later this summer, the season is likely to be a blockbuster.

Why? Because the oceans are screaming at us.

One-quarter of the world’s population is currently water-stressed, using up almost their entire fresh water supply each year. The UN predicts that by 2030, this will climb to two-thirds of the population.

Freshwater is perhaps the world’s most essential resource, but climate change is enhancing its scarcity. An unexpected source may have the potential to provide some relief: offshore aquifers, giant undersea bodies of rock or sediment that hold and transport freshwater. But researchers don’t know how the water gets there, a question that needs to be resolved if we want to understand how to manage the water stored in them.

For decades, scientists have known about an aquifer off the US East Coast. It stretches from Martha’s Vineyard to New Jersey and holds almost as much water as two Lake Ontarios. Research presented at the American Geophysical Union conference in December attempted to explain where the water came from—a key step in finding out where other undersea aquifers lie hidden around the world.

There are games for which I have great admiration, pleasant memories, and an entirely dreadful set of skills and outcomes. Heroes of Might & Magic III (or HoMM 3) has long been one of those games.

I have played it on just about every PC I've owned, ever since it chipped away at my college GPA. I love being tasked with managing not only heroes, armies, resources, villages, and battlefield positioning but also time itself. If you run around the map clicking to discover every single power-up and resource pile, using up turn after turn, you will almost certainly let your enemy grow strong enough to conquer you. But I do this, without fail. I get halfway into a campaign and the (horse cart) wheels fall off, so I set the game aside until the click-to-move-the-horsey impulse comes back.

With the release of Songs of Conquest in 1.0 form on PC today (Steam, GOG, Epic), I feel freed from this loop of recurrent humbling. This title from Lavapotion and Coffee Stain Publishing very much hits the same pleasure points of discovery and choice as HoMM 3. But Songs of Conquest has much easier onboarding, modern resolutions, interfaces that aren't too taxing (to the point of being Verified on Steam Deck), and granular difficulty customization. More importantly for most, it has its own stories and ideas. If you love fiddling with stuff turn by turn, it's hard to imagine you won't find something in Songs of Conquest to hook you.

There are a couple of ways to read the announcement from the Federal Aviation Administration that it's kicking off a new environmental review of SpaceX's plan to launch the most powerful rocket in the world from Florida.

The FAA said on May 10 that it plans to develop an Environmental Impact Statement (EIS) for SpaceX's proposal to launch Starships from NASA's Kennedy Space Center in Florida. The FAA ordered this review after SpaceX updated the regulatory agency on the projected Starship launch rate and the design of the ground infrastructure needed at Launch Complex 39A (LC-39A), the historic launch pad once used for Apollo and Space Shuttle missions.

At the same time, the US Space Force is overseeing a similar EIS for SpaceX's proposal to take over a launch pad at Cape Canaveral Space Force Station, a few miles south of LC-39A. This launch pad, designated Space Launch Complex 37 (SLC-37), is available for use after United Launch Alliance's last Delta rocket lifted off there in April.

An asteroid that has been wandering through space for billions of years is going to have been bombarded by everything from rocks to radiation. Billions of years of traveling through interplanetary space increases the odds of colliding with something in the vast emptiness, and at least one of those impacts had enough force to leave the asteroid Ryugu forever changed.

When the Japanese Space Agency’s Hayabusa2 spacecraft touched down on Ryugu, it collected samples from the surface that revealed that particles of magnetite (which is usually magnetic) in the asteroid’s regolith are devoid of magnetism. A team of researchers from Hokkaido University and several other institutions in Japan are now offering an explanation for how this material lost most of its magnetic properties. Their analysis showed that it was caused by at least one high-velocity micrometeoroid collision that broke the magnetite’s chemical structure down so that it was no longer magnetic.

“We surmised that pseudo-magnetite was created [as] the result of space weathering by micrometeoroid impact,” the researchers, led by Hokkaido University professor Yuki Kimura, said in a study recently published in Nature Communications.

Ruth Ann Norton used to look forward to seeing the blue flame that danced on the burners of her gas stove. At one time, she says, she would have sworn that preparing meals with the appliance actually made her a better cook.

But then she started learning about the toxic gases, including carbon monoxide, formaldehyde, and other harmful pollutants that are emitted by stoves into the air, even when they’re turned off.

“I’m a person who grew up cooking, and love that blue flame,” said Norton, who leads the environmental advocacy group known as the Green & Healthy Homes Initiative. “But people fear what they don’t know. And what people need to understand really strongly is the subtle and profound impact that this is having—on neurological health, on respiratory health, on reproductive health.”

In July last year, OpenAI announced the formation of a new research team that would prepare for the advent of supersmart artificial intelligence capable of outwitting and overpowering its creators. Ilya Sutskever, OpenAI’s chief scientist and one of the company’s co-founders, was named as the co-lead of this new team. OpenAI said the team would receive 20 percent of its computing power.

Now OpenAI’s “superalignment team” is no more, the company confirms. That comes after the departures of several researchers involved, Tuesday’s news that Sutskever was leaving the company, and the resignation of the team’s other co-lead. The group’s work will be absorbed into OpenAI’s other research efforts.

Unraveling how consciousness arises out of particular configurations of organic matter is a quest that has absorbed scientists and philosophers for ages. Now, with AI systems behaving in strikingly conscious-looking ways, it is more important than ever to get a handle on who and what is capable of experiencing life on a conscious level. As Christof Koch writes in Then I Am Myself the World, "That you are intimately acquainted with the way life feels is a brute fact about the world that cries out for an explanation." His explanation—bounded by the limits of current research and framed through Koch’s preferred theory of consciousness—is what he eloquently attempts to deliver.

Koch, a physicist, neuroscientist, and former president of the Allen Institute for Brain Science, has spent his career hunting for the seat of consciousness, scouring the brain for physical footprints of subjective experience. It turns out that the posterior hot zone, a region in the back of the neocortex, is intricately connected to self-awareness and experiences of sound, sight, and touch. Dense networks of neocortical neurons in this area connect in a looped configuration; output signals feedback into input neurons, allowing the posterior hot zone to influence its own behavior. And herein, Koch claims, lies the key to consciousness.

According to integrated information theory (IIT)—which Koch strongly favors over a multitude of contending theories of consciousness—the Rosetta Stone of subjective experience is the ability of a system to influence itself: to use its past state to affect its present state and its present state to influence its future state.

With the debut of remarkably effective weight-loss drugs, America's high obesity rate and its uniquely astronomical prescription drug pricing appear to be set on a catastrophic collision course—one that threatens to "bankrupt our entire health care system," according to a new Senate report that modeled the economic impact of the drugs in different uptake scenarios.

If just half of the adults in the US with obesity start taking a new weight-loss drug, such as Wegovy, the collective cost would total an estimated $411 billion per year, the analysis found. That's more than the $406 billion Americans spent in 2022 on all prescription drugs combined.

While the bulk of the spending on weight-loss drugs will occur in the commercial market—which could easily lead to spikes in health insurance premiums—taxpayer-funded Medicare and Medicaid programs will also see an extraordinary financial burden. In the scenario that half of adults with obesity go on the drug, the cost to those federal programs would total $166 billion per year, rivaling the programs' total 2022 drug costs of $175 billion.

Apple’s initial pitch for the tvOS and the Apple TV as it currently exists was centered around apps. No longer a mere streaming box, the Apple TV would also be a destination for general-purpose software and games, piggybacking off of the iPhone's vibrant app and game library.

That never really panned out, and the Apple TV is still mostly a box for streaming TV shows and movies. But the same App Store rule change that recently allowed Delta, PPSSPP, and other retro console emulators onto the iPhone and iPad could also make the Apple TV appeal to people who want a small, efficient, no-fuss console emulator for their TVs.

So far, few of the emulators that have made it to the iPhone have been ported to the Apple TV. But earlier this week, the streaming box got an official port of RetroArch, the sprawling collection of emulators that runs on everything from the PlayStation Portable to the Raspberry Pi. RetroArch could be sideloaded onto iOS and tvOS before this, but only using awkward workarounds that took a lot more work and know-how than downloading an app from the App Store.

Stuff posted on Reddit is getting incorporated into ChatGPT, Reddit and OpenAI announced on Thursday. The new partnership grants OpenAI access to Reddit’s Data API, giving the generative AI firm real-time access to Reddit posts.

Reddit content will be incorporated into ChatGPT "and new products," Reddit's blog post said. The social media firm claims the partnership will "enable OpenAI’s AI tools to better understand and showcase Reddit content, especially on recent topics." OpenAI will also start advertising on Reddit.

The deal is similar to one that Reddit struck with Google in February that allows the tech giant to make "new ways to display Reddit content" and provide "more efficient ways to train models," Reddit said at the time. Neither Reddit nor OpenAI disclosed the financial terms of their partnership, but Reddit's partnership with Google was reportedly worth $60 million.

Cats and robots are a winning combination, as evidenced by all those videos of kitties riding on Roombas. And now we have Cat Royale, a "multispecies" live installation in which three cats regularly "played" with a robot over 12 days, carefully monitored by human operators. Created by computer scientists from the University of Nottingham in collaboration with artists from a group called Blast Theory, the installation debuted at the World Science Festival in Brisbane, Australia, last year and is now a touring exhibit. The accompanying YouTube video series recently won a Webby Award, and a paper outlining the insights gleaned from the experience was similarly voted best paper at the recent Computer-Human Conference (CHI’24).

"At first glance, the project is about designing a robot to enrich the lives of a family of cats by playing with them," said co-author Steve Benford of the University of Nottingham, who led the research. "Under the surface, however, it explores the question of what it takes to trust a robot to look after our loved ones and potentially ourselves." While cats might love Roombas, not all animal encounters with robots are positive: Guide dogs for the visually impaired can get confused by delivery robots, for example, while the rise of lawn mowing robots can have a negative impact on hedgehogs, per Benford et al.

Blast Theory and the scientists first held a series of exploratory workshops to ensure the installation and robotic design would take into account the welfare of the cats. "Creating a multispecies system—where cats, robots, and humans are all accounted for—takes more than just designing the robot," said co-author Eike Schneiders of Nottingham's Mixed Reality Lab about the primary takeaway from the project. "We had to ensure animal well-being at all times, while simultaneously ensuring that the interactive installation engaged the (human) audiences around the world. This involved consideration of many elements, including the design of the enclosure, the robot, and its underlying systems, the various roles of the humans-in-the-loop, and, of course, the selection of the cats.”

That's how notable Valve leaker "Gabe Follower" describes Deadlock, a Valve game that is seemingly in playtesting at the moment, for which a few screenshots have leaked out.

The game has been known as "Neon Prime" and "Citadel" at prior points. It's a "Competitive third-person hero-based shooter," with six-on-six battles across a map with four "lanes." That allows for some of the "Tower defense mechanics" mentioned by Gabe Follower, along with "fast travel using floating rails, similar to Bioshock Infinite." The maps reference a "modern steampunk European city (little bit like Half-Life)," after "bad feedback" about a sci-fi theme pushed the development team toward fantasy.
