The research team found that the Big Bang’s rapid early expansion can emerge naturally from this simple, consistent theory of quantum gravity, without adding any extra ingredients. This early burst of expansion, often called inflation, is a central idea in modern cosmology because it explains why the universe looks the way it does today.

Their model also predicts a minimum amount of primordial gravitational waves, which are tiny ripples in spacetime geometry created in the first moments after the Big Bang. These signals may be detectable in upcoming experiments, offering a rare chance to test ideas about the universe’s quantum origins.

[…] The team plans to refine their predictions for upcoming experiments to explore how their framework connects to particle physics and other puzzles about the early universe. Their long-term goal is to strengthen the bridge between quantum gravity and observational cosmology.

Researchers found that these gloves can unintentionally transfer particles onto lab tools used to analyze air, water, and other environmental samples. The contamination comes from stearates, which are not plastics but can closely resemble them during testing. Because of this, scientists may be detecting particles that are not true microplastics. To reduce this issue, U-M researchers Madeline Clough and Anne McNeil recommend using cleanroom gloves, which release far fewer particles.

Stearates are salt-based, soap-like substances added to disposable gloves to help them separate easily from molds during manufacturing. However, their chemical similarity to certain plastics makes them difficult to distinguish in lab analyses, increasing the risk of false positives when studying microplastic pollution.

Andrea Marinoni at the University of Cambridge, UK, and his colleagues saw that the amount of energy needed to run a data centre had been steadily increasing of late and was likely to “explode” in the coming years, so wanted to quantify the impact. The researchers took satellite measurements of land surface temperatures over the past 20 years and cross-referenced them against the geographical coordinates of more than 8400 AI data centers. Recognizing that surface temperature could be affected by other factors, the researchers chose to focus their investigation on data centers located away from densely populated areas.

They discovered that land surface temperatures increased by an average of 2C (3.6F) in the months after an AI data center started operations. In the most extreme cases, the increase in temperature was 9.1C (16.4F). The effect wasn’t limited to the immediate surroundings of the data centers: the team found increased temperatures up to 10 kilometers away. Seven kilometers away, there was only a 30 percent reduction in the intensity. “The results we had were quite surprising,” says Marinoni. “This could become a huge problem.”

Using population data, the researchers estimate that more than 340 million people live within 10 kilometers of data centers, so live in a place that is warmer than it would be if the data centre hadn’t been built there. Marinoni says that areas including the Bajio region in Mexico and the Aragon province in Spain saw a 2C (3.6F) temperature increase in the 20 years between 2004 and 2024 that couldn’t otherwise be explained.

The description stands out at a time when many of Microsoft’s built-in tools, including Clipchamp and Copilot, rely on web technologies and Progressive Web App architectures. The company’s commitment to native performance suggests that some long-standing frustrations around responsiveness, memory use, and interface consistency could finally be addressed.

For Windows developers, Huyn’s comments hint at a change in direction. Microsoft’s recent development priorities have leaned heavily on web-based approaches, with Progressive Web Apps (PWAs) replacing or supplementing many native programs. […] Exactly which applications will be rebuilt, or how strictly “100% native” will be enforced, remains unclear. Some current Microsoft apps classified as native still depend on WebView for specific features. But the renewed emphasis already has developers paying attention.

Last year, just before the Fourth of July holiday, the US Space Force officially took ownership of a new operating system for the GPS navigation network, raising hopes that one of the military’s most troubled space programs might finally bear fruit. The GPS Next-Generation Operational Control System, or OCX, is designed for command and control of the military’s constellation of more than 30 GPS satellites. It consists of software to handle new signals and jam-resistant capabilities of the latest generation of GPS satellites, GPS III, which started launching in 2018. The ground segment also includes two master control stations and upgrades to ground monitoring stations around the world, among other hardware elements.

RTX Corporation, formerly known as Raytheon, won a Pentagon contract in 2010 to develop and deliver the control system. The program was supposed to be complete in 2016 at a cost of $3.7 billion. Today, the official cost for the ground system for the GPS III satellites stands at $7.6 billion. RTX is developing an OCX augmentation projected to cost more than $400 million to support a new series of GPS IIIF satellites set to begin launching next year, bringing the total effort to $8 billion.

Although RTX delivered OCX to the Space Force last July, the ground segment remains nonoperational. Nine months later, the Pentagon may soon call it quits on the program. Thomas Ainsworth, assistant secretary of the Air Force for space acquisition and integration, told Congress last week that OCX is still struggling.

As spotted by Reddit users (via Tarun Vats on X), a Quick Share app update is rolling out via the Galaxy Store on older Samsung devices that appears to add support for AirDrop file sharing with Apple devices. Users report seeing the same new “Share with Apple devices” section we first saw on Galaxy S26 devices in the Settings app after updating Quick Share.

The update is reportedly showing up on Galaxy models ranging from the Galaxy S22 to last year’s Galaxy S25 series. The catch, however, is that the feature doesn’t seem to be working yet. It’s appearing on devices running One UI 8 as well as the One UI 8.5 beta, but enabling the toggle doesn’t activate the functionality for now.

Users say that turning on the feature doesn’t make their device visible to Apple devices, and no Apple devices show up in Quick Share either. It’s possible Samsung or Google still needs to enable it server-side, but it does confirm that broader rollout to older Galaxy devices is coming. The feature could arrive fully with the One UI 8.5 update.

According to the FTC, OkCupid’s privacy policy at the time noted that the company wouldn’t share a user’s personal information with others, except for some cases including “service providers, business partners, other entities within its family of businesses.” However, the lawsuit accused OkCupid of sharing three million photos of its users to Clarifai, which the FTC claims is a “unrelated third party” that didn’t fall under the allowed entities. On top of that, the lawsuit alleged that OkCupid didn’t inform its users of this data sharing, nor give them a chance to opt out.

Moving forward, the settlement would “permanently prohibit” Match Group, which owns OkCupid, and Humor Rainbow, which operates OkCupid, from misrepresenting what kind of personal information it collects, the purpose for collecting the data and any consumer choices to prevent data collection. Even after the 2014 incident, OkCupid was found with security flaws that could’ve exposed user account info but, which were quickly patched in 2020.

Too many lines of code to analyze, armies of AI assistants to wrangle, and lengthy prompts to draft are among the laments by hard-core AI adopters. Consultants at Boston Consulting Group (BCG) have dubbed the phenomenon “AI brain fry,” a state of mental exhaustion stemming “from the excessive use or supervision of artificial intelligence tools, pushed beyond our cognitive limits.”

The rise of AI agents that tend to computer tasks on demand has put users in the position of managing smart, fast digital workers rather than having to grind through jobs themselves. “It’s a brand-new kind of cognitive load,” said Ben Wigler, co-founder of the start-up LoveMind AI. “You have to really babysit these models.” […] “There is a unique kind of reward hacking that can go on when you have productivity at the scale that encourages even later hours,” Wigler said.

[Adam Mackintosh, a programmer for a Canadian company] recalled spending 15 consecutive hours fine-tuning around 25,000 lines of code in an application. “At the end, I felt like I couldn’t code anymore,” he recalled. “I could tell my dopamine was shot because I was irritable and didn’t want to answer basic questions about my day.”

BCG recommends in a recently published study that company leaders establish clear limits regarding employee use and supervision of AI. However, “That self-care piece is not really an America workplace value,” Wigler said. “So, I am very skeptical as to whether or not its going to be healthy or even high quality in the long term.”

In an effort to gather material for its LLM training, Meta used BitTorrent to download pirated books from Anna’s Archive and other shadow libraries. According to several authors, Meta facilitated the infringement of others by "seeding” these torrents. This week, the court granted the authors permission to add these claims to their complaint, despite openly scolding their counsel for “lame excuses” and “Meta bashing.” […] The judge acknowledged that the contributory infringement claim could and should have been added back in November 2024, when the authors amended their complaint to include the distribution claim. After all, both claims arise from the same factual allegations about Meta’s torrenting activity.

“The lawyers for the named plaintiffs have no excuse for neglecting to add a contributory infringement claim based on these allegations back in November 2024,” Judge Chhabria wrote. The lawyers of the book authors claimed that the delay was the result of newly produced evidence that had “crystallized” their understanding of Meta’s uploading activity. However, that did not impress the judge. He called it a “lame excuse” and “a bunch of doubletalk,” noting that if the missing discovery truly prevented the contributory claim from being added in November 2024, the same logic would have prevented the distribution claim from being added at that time as well. “Rather than blaming Meta for producing discovery late, the plaintiffs’ lawyers should have been candid with the Court, explaining that they missed an issue in a case of first impression..,” the order reads.

Judge Chhabria went further, noting that the authors’ law firm, Boies Schiller, showed “an ongoing pattern” of distracting from its own mistakes by attacking Meta. He pointed specifically to the dispute over when Meta disclosed its fair use defense to the distribution claim, which we covered here recently, characterizing it as a false distraction. “The lawyers for the plaintiffs seem so intent on bashing Meta that they are unable to exercise proper judgment about how to represent the interests of their clients and the proposed class members,” the order reads. Despite the criticism, Chhabria granted the motion. […] For now, the case moves forward with a fourth amended complaint, three new loan-out companies added as named plaintiffs, and a growing list of BitTorrent-related claims for Judge Chhabria to resolve.

According to Melbourne-based software developer Zach Manson, a team member used the AI to fix a simple typo in a pull request. Copilot did the job, but it also took the liberty of editing the PR’s description to include this message: “Quickly spin up Copilot coding agent tasks from anywhere on your macOS or Windows machine with Raycast.” A quick search of that phrase on GitHub shows that the same promotional text appears in over 11,000 pull requests across thousands of repositories. Even merge requests on GitLab aren’t safe from the injection.

So what’s happening? Well, Raycast has a Copilot extension that can do things like create pull requests from a natural language command. The ad directly names Raycast, so you might think that Raycast is injecting the promo into the PRs to market its own app. But it is more likely that Microsoft is the one doing the injecting. If you look at the raw markdown of the affected pull requests, there is a hidden HTML comment, “START COPILOT CODING AGENT TIPS” placed right just before the ad tip. This suggests Microsoft is using the comment to insert a “tip” that points back to its own developer ecosystem or partner integrations.

The suspension includes all of Sony’s memory card lines, including CFexpress Type A, CFexpress Type B, and SD cards. The 240GB, 480GB, 960GB, and 1920GB capacity Type A cards have been suspended, as have the 480GB and 240GB Type B cards. The full gamut of Sony’s high-end SD cards has also been suspended, including the 256GB, 128GB, and 64GB TOUGH-branded cards and the lower-end 512GB, 256GB, 128GB, and 256GB plainly-branded Sony cards, which cap out at V60 speeds. Even Sony’s lower-end, V30 128GB and 64GB SD cards have been suspended, showcasing that the SSD shortage affects all types of solid state, not just the high-end ones.

It appears that only the 960GB CFexpress Type B card and the lowest-end SF-UZ series SD cards remain in production. However, those UHS-I SD cards are discontinued in the United States outside of a scant few retailers and resellers. “We sincerely apologize for any inconvenience this may cause our customers,” Sony concludes.

Sweeping job cuts at Big Tech companies have become an annual tradition. How executives explain those decisions, however, has changed. Out are buzzwords like efficiency, over-hiring, and too many management layers. Today, all explanations stem from artificial intelligence (AI). In recent weeks, giants including Google, Amazon, Meta, as well as smaller firms such as Pinterest and Atlassian, have all announced or warned of plans to shrink their workforce, pointing to developments in AI that they say are allowing their firms to do more with fewer people. […] But explaining cuts by pointing to advances in AI sounds better than citing cost pressures or a desire to please shareholders, says tech investor Terrence Rohan, who has had a seat on many company boards. “Pointing to AI makes a better blog post,” Rohan says. “Or it at least doesn’t make you seem as much the bad guy who just wants to cut people for cost-effectiveness.”

That does not mean there is no substance behind the words, Rohan added. Some of the companies he’s backing are using code that is 25% to 75% AI-generated. That is a sign of the real threat that AI tools for writing code represent to jobs such as software developer, computer engineer and programmer, posts once considered a near-guarantee of highly paid, stable careers. “Some of it is that the narrative is changing, some of it is that we really are starting to see step changes in productivity,” Anne Hoecker, a partner at Bain who leads the consultancy’s technology practice, says of the recent job cuts. “Leaders more recently are seeing these tools are good enough that you really can do the same amount of work with fundamentally less people.”

There is another way that AI is driving job cuts — and it has nothing to do with the technical abilities of coding tools and chatbots. Amazon, Meta, Google and Microsoft are collectively planning to pour $650 billion into AI in the coming year. As executives hunt for ways to try to ease investor shock at those costs, many are landing on payroll, typically tech firms’ single biggest expense. […] Although the expense of, for example, 30,000 corporate Amazon employees is dwarfed by that company’s AI spending plans, firms of this size will now take any opportunity to cut costs, Rohan says. “They’re playing a game of inches,” Rohan says of cuts at Big Tech firms. “If you can even slightly tune the machine, that is helpful.” Hoecker says cutting jobs also signals to stock market investors worried about the “real and huge” cost of AI development that executives are not blithely writing blank cheques. “It shows some discipline,” says Hoecker. “Maybe laying off people isn’t going to make much of a dent in that bill, but by creating a little bit of cashflow, it helps.”

[Using blockchain-based security, the e-cig cartridge] would use a camera to scan some form of ID and then also take a video of the user’s face. Once it verifies your identity and determines you’re old enough to vape, it translates that information into anonymized tokens. That info goes to an identity service like ID.me or Clear. If approved, it bounces back to the app, which then uses a Bluetooth signal to give the vape the OK to turn on.

“Everything is tokenized,” [says Ispire CEO Michael Wang]. “As a result of this process, we don’t communicate consumer personal private information.” He says the process takes about a minute and a half… After that onetime check, the Bluetooth connection on the phone will recognize when the vape cartridge is nearby and keep it unlocked. Move the vape too far away from the phone, and it shuts off again. Based on testing, the companies behind Ike Tech claim this process has a 100 percent success rate in age verification, more or less calling the tech infallible. “The FDA told us it’s the holy grail technology they were looking for,” Wang says. “That’s word-for-word what they said when we met with them....”

Wang says the goal is to implement additional features in the verification process, like geo-fencing, which would force the vape to shut off while near a school or on an airplane. In the future, the plan is to license this biometric verification tech to other e-cig companies. The tech may also grow to include fingerprint readers and expand to other product categories; Wang suggests guns, which have a long history of age-verification features not quite working.

Steve Wozniak, cofounder, Apple: I told my dad when I was in high school, “I’m going to own a computer someday.” My dad said, “It costs as much as a house.” And I sat there at the table — I remember right where we were sitting — and I said, “I’ll live in an apartment.” I was going to have a computer if it was ever possible. I didn’t need a house.

Bill Fernandez: The computer was very basic. It was working, and we were starting to talk about how we could hook a teletype up to it. Mrs. Wozniak called a reporter from the San Jose Mercury, and he came over with a photographer. We set up the computer on the floor of Steve Wozniak’s bedroom.

Well, the core integrated circuit that ran the power supply that I built was an old reject part. We turned on the computer, and the power supply smoked and burnt out the circuitry. So we didn’t get our photos in the paper with an article about the boy geniuses.

Steve Wozniak: I showed them what it would cost and how it would work and what it could do with my little demos. They had all the engineering people and the marketing people, and they turned me down. That was the first of five turndowns from Hewlett-Packard. Steve Jobs and I had to go into business on our own.

But this much is clear: The company has always been at its best when its original quirky humanity and willingness to be an outlier shine through.

Mark Johnson, Apple employee No. 13: I was in Cupertino just yesterday. It’s totally different. They own Cupertino now.

Jonathan Rotenberg, who cofounded the Boston Computer Society in 1977 at age 13: People want to hate Apple, because it is big and powerful. But Apple has an underlying moral purpose that is immensely deep and expansive…

Mike Markkula, the early retiree from Intel whose guidance and money turned the garage startup into a company: The culture mattered. People were there for the right reasons — to build something transformative — not just to make money. That alignment produced extraordinary results…

Steve Wozniak: Everything you do in life should have some element of joy in it. Even your work should have an element of joy… When you’re about to die, you have certain memories. And for me, it’s not going to be Apple going public or Apple being huge and all that. It’s really going to be stories from the period when humble people spotted something that was interesting and followed it

I’ll be thinking of that when I die, along with a lot of pranks I played. The important things.

After fighting to sell its vehicles directly to buyers, Rivian threatened to take its case to voters with a ballot measure to permit direct sales. The dealers blinked. The state’s dealer lobby not only dropped its opposition to a sales loophole for Rivian and rival EV-maker Lucid, but also encouraged lawmakers to approve one. The measure became law this month…

New auto entrants like Rivian, and Tesla before it, have spent years contending with long-established U.S. state laws that require new cars to be sold through independent franchised dealers. The auto startups — typically makers of EVs — argue that they can offer a better experience by selling directly to consumers, much as Apple sells iPhones through its own stores and online. Rivian CEO RJ Scaringe has said the company is committed to direct-only sales because it’s more profitable and gives the company control over how its vehicles are sold, marketed and maintained. The Washington compromise riled traditional automakers, including General Motors, Ford and Toyota, which lobbied against it, arguing it unfairly advantages startups. A trade group representing the automakers called it discriminatory and argued the exception could one day open the door to Chinese EV makers…

German automaker Volkswagen is currently facing several lawsuits from dealers over its plan to sell new Scout vehicles directly to consumers. Dealers say independent franchises are vital to the car-buying process, creating competition between dealerships that keeps prices affordable for consumers, while providing valuable services such as repairs, warranty work and financing… Yet for Washington’s dealers, the prospect of putting franchise laws up for a popular vote laid bare a tough reality: given the choice, many car buyers want the freedom to avoid dealerships. Rivian’s polling, which the company shared with lawmakers, showed nearly 70% of respondents favored allowing direct sales when asked whether they would support manufacturers selling cars directly to consumers…

The fight comes at a critical time for Rivian, which is launching a new, more affordable SUV in a bid to make consistent profits amid a downturn in U.S. EV sales… Rivian is able to directly sell cars in roughly half of U.S. states, but a number of them limit how many locations the company can operate. They can’t disclose the price, though. For that, customers must go online.
