More than two-thirds of babies under two use screens, a report has found, and some are exposed for up to eight hours a day. Nearly a third of newborns were found to be watching screens for more than three hours a day, while almost 20 percent of infants of four to 11 months used screens for more than an hour a day. The report comes after the government issued guidance that children under two do not use screens at all, apart from communal activities such as video-calling relatives.

In a review of the current research, researchers found evidence linking screen time to poorer outcomes for children, including an increased risk of obesity, short-sightedness, sleep and behavioural difficulties, and later challenges with friendships. […] The research also revealed why children and parents use screens, with families reporting children doing so for educational purposes, entertainment, play and to communicate and bond with others. Parents, meanwhile, used screens to occupy or distract children, which helped caregivers to complete domestic duties, paid employment and other caring responsibilities. Nearly a quarter of parents — 23.6 percent — either had no childcare or were not aware of the government’s early years offer.

Musk on Tuesday was the first witness called to testify in the trial. He spoke about his upbringing, his many companies, his role in founding OpenAI and his understanding of its structure. Musk said in his testimony that he was not opposed to the creation of a small for-profit subsidiary, “as long as the tail didn’t wag the dog.” Musk said he was motivated to start OpenAI to serve as a counterweight to Google. He got the idea after an argument he had with Google co-founder Larry Page, who called Musk a “speciesist for being pro-human,” he testified. “I could have started it as a for profit and I chose not to,” Musk said on the stand.

Earlier, attorneys for Musk and OpenAI presented their opening arguments to the jury. Musk’s lead trial lawyer, Steven Molo, delivered the opening statement for the Tesla and SpaceX CEO. OpenAI lawyer William Savitt gave the opening statement for the AI company, Altman and Brockman. OpenAI has characterized Musk’s lawsuit as a baseless “harassment campaign.” The company said Monday in a post on X that it “can’t wait to make our case in court where both the truth and the law are on our side.”

During his testimony on Tuesday, Musk repeatedly emphasized that he founded OpenAI to serve as a counterweight to Google. He said he got the idea after an argument about AI safety with Google co-founder Larry Page, who Musk said called him “a speciesist for being pro-human.” Musk said he was concerned Page was not taking AI safety seriously, so he wanted there to be an nonprofit, open source alternative to Google. “I could have started it as a for profit and I chose not to,” Musk said on the stand.

University of Oregon chemist Christopher Hendon loves his coffee — so much so that studying all the factors that go into creating the perfect cuppa constitutes a significant area of research for him. His latest project: discovering a novel means of measuring the flavor profile of coffee simply by sending an electrical current through a sample beverage. The results appear in a new paper published in the journal Nature Communications.

[…] The coffee industry typically uses a method for measuring the refractive index of coffee — i.e., how light bends as it travels through the liquid — to determine strength, but it doesn’t capture the contribution of roast color to the overall flavor profile. So for this latest study, Hendon decided to focus on roast color and beverage strength, the two variables most likely to affect the sensory profile of the final cuppa. His solution turned out to be quite simple. Hendon repurposed an electrochemical tool called a potentiostat, typically used to test battery and fuel cell performance. Hendon used the tool to measure how electricity interacted with the liquid. He found that this provided a better measurement of the flavor profile. He even tested it on four different samples of coffee beans and successfully identified the distinctive signature of a batch that had failed the roaster’s quality-control process.

Granted, one’s taste in coffee is fairly subjective, so Hendon’s goal was not to achieve a “perfect” cup but to give baristas a simple tool to consistently reproduce flavor profiles more tailored to a given customer’s taste. “It’s an objective way to make a statement about what people like in a cup of coffee,” said Hendon. “The reason you have an enjoyable cup of coffee is almost certainly that you have selected a coffee of a particular roast color and extracted it to a desired strength. Until now, we haven’t been able to separate those variables. Now we can diagnose what gives rise to that delicious cup.”

[New York opthalmologist] Dr. Eric Rosenberg of SightMD completed the initial procedure in October 2025 and has since performed hundreds of additional cases using ScopeXR, a surgical platform he co-developed for Apple’s mixed reality device. ScopeXR streams live feeds from 3D digital surgical microscopes directly into the Vision Pro, which lets the surgeon view the operative field in stereoscopic 3D while overlaying preoperative diagnostic data. The platform also supports real-time remote collaboration, allowing surgeons to virtually join procedures and see exactly what the operating surgeon sees.

In the info page of an affected game, you’d see a new validity period and a “remaining time” deadline. At first, this seemed like a software bug, but now PlayStation Support has confirmed its authenticity to multiple users. PlayStation owners are furious about the change.

From what we’ve seen, this DRM is intended for digital game copies. It works by instating a mandatory online check-in where you have to connect to the internet within a rolling 30-day window or risk losing access to the game. Afterward, you can still restore access, but you’ll need an internet connection to renew the game’s license first. So far, it seems like only games installed after the recent March firmware update are affected.

Affected customers report that setting your PS4 or PS5 as the primary console doesn’t alleviate this check-in policy either. No matter what, any game you download from now on will feature this new requirement, effectively eliminating the concept of offline play for even single-player titles.

Often, app developers will display the lower monthly price to highlight the discount the customer would receive if they purchase the annual subscription instead of the monthly option. If the user is on the fence about a longer-term commitment, the notion that they’re getting a better deal can help to push them toward the annual option.

Now, Apple is essentially formalizing what these developers were already doing, which allows it to also craft a set of policies around how these subscription offers are to be displayed so as not to mislead customers about the true cost of the deals.

However, the option will not be available to developers in the United States or Singapore at launch. While Apple didn’t offer an explanation for this, it’s still in App Store litigation in the U.S. around the specifics of the court’s ruling in its case with Epic Games around how Apple can charge for subscriptions. Apple likely doesn’t want to complicate the matter further until that matter is finalized. Singapore, meanwhile, also has a sophisticated payments market with strong consumer rules, which is why it may have been left out of the initial release.

For its famous intractability, the Bloomberg Terminal has long inspired devotion, bordering on obsession. Among traders, the ability to chart a path through the software’s dizzying scrolls of numbers and text to isolate far-flung information is the mark of a seasoned professional. But as a greater mass of data is fed into the Terminal — not only earnings and asset prices, but weather forecasts, shipping logs, factory locations, consumer spending patterns, private loans, and so on — valuable information is being lost. “It has become more and more untenable,” says Shawn Edwards, chief technology officer at Bloomberg. “You miss things, or it takes too long.”

To try to remedy the problem, Bloomberg is testing a chatbot-style interface for the Terminal, ASKB (pronounced ask-bee), built atop a basket of different language models. The broad idea is to help finance professionals to condense labor-intensive tasks, and make it possible to test abstract investment theses against the data through natural language prompts. As of publication, the ASKB beta is open to roughly a third of the software’s 375,000 users; Bloomberg has not specified a date for a full release.

The agreement was reported less than a day after Google employees demanded CEO Sundar Pichai block the Pentagon from using its AI amid concerns that it would be used in “inhumane or extremely harmful ways.” If the agreement is confirmed, it would place Google alongside OpenAI and xAI, which have also made classified AI deals with the US government. Anthropic was also among that list until it was blacklisted by the Pentagon for refusing the Department of Defense’s demands to remove weapon and surveillance-related guardrails from its AI models.

Citing a single anonymous source “with knowledge of the situation,” The Information reports that the deal states that both parties have agreed that the search giant’s AI systems shouldn’t be used for domestic mass surveillance or autonomous weapons “without appropriate human oversight and control.” But the contract also says it doesn’t give Google “any right to control or veto lawful government operational decision-making,” which would suggest the agreed restrictions are more of a pinky promise than legally binding obligations.

The United Arab Emirates announced Tuesday that it would exit the Organization of the Petroleum Exporting Countries (source paywalled; alternative source), or OPEC, along with the wider group of partners known as OPEC+, effective May 1, in what could be a blow to control over prices by the group, long led in practice by Saudi Arabia. The move “reflects the UAE’s long-term strategic and economic vision and evolving energy profile” read an official statement carried by a UAE state news agency, as disruptions “in the Strait of Hormuz continues to affect supply dynamics.”

[…] The UAE is the second Persian Gulf country to leave the group after Qatar terminated its membership in 2019. The UAE has been a member of OPEC since 1971. The latest departure leaves in place 11 core members: Algeria, Congo, Equatorial Guinea, Gabon, Iran, Iraq, Kuwait, Libya, Nigeria, Saudi Arabia and Venezuela.

Duncan is asking potential buyers to email him to discuss deal specifics, but he said it would be a private transaction that doesn’t require the buyer to sell their stock outright. On LinkedIn, he also said the homebuyer would “continue to retain 20% of the upside value of the shares exchanged for the duration of the lockup period.”

Duncan, who described himself as a longtime Bay Area resident who moved to Miami during the pandemic, bought the property in 2019 for $4.75 million. It’s currently occupied by “a high-profile VC,” he said, but he declined to identify the VC.

A divided U.S. Supreme Court on Monday heard a dispute over labels on the popular Roundup weed killer, which thousands of people blame for their cancers. How the Supreme Court rules could have implications for tens of thousands of lawsuits against Roundup maker Monsanto, which is now owned by Bayer. The case centers on who decides about warning labels on chemicals: the federal government — or states or juries. […] The justices will not be evaluating whether glyphosate causes cancer. Rather, they’ll consider who should decide what appears on warning labels and whether states have a role to play after the EPA weighs in.

The current U.S. solicitor general backed Monsanto. Sarah Harris, his principal deputy, said the Environmental Protection Agency is in the driver’s seat, not anyone in Missouri. “Missouri thus requires adding cancer warnings but federal law requires EPA to approve new warnings and tasks EPA with deciding what label changes would mitigate any health risks,” Harris argued. “State law must give way.” Several justices, including Brett Kavanaugh, appeared to agree with Monsanto’s argument about the need for a single, uniform standard across the country.

But others, like Chief Justice John Roberts, wondered what would happen if the federal government moved more slowly than states did, who wanted to act quickly on information about new dangers. “Well, it does undermine the uniformity,” Roberts said. “On the other hand, if it turns out they were right, it might have been good if they had an opportunity to do something, to call this danger to the attention of people while the federal government was going through its process,” he said about states.

Justice Ketanji Brown Jackson asked about the emergence of new science, and the EPA’s reviews. “There’s a 15-year window between when that product has to be re-registered again and lots of things can happen in science, in terms of development about the product,” she said. Bayer, which now owns Monsanto, only sells Roundup that contains glyphosate to farmers and businesses these days. Bayer has been pushing to resolve scores of the residential cases through a sweeping settlement, trying to put the costly claims behind it.

Infrasound sits below roughly 20 Hz, the lower limit of what the human ear can ordinarily detect. It’s generated by storms, by volcanic activity, by tectonic rumblings deep in the Earth’s crust, and (this is the part that matters) by the mundane mechanical heartbeat of cities: ageing pipes, HVAC systems, traffic, industrial machinery. “Infrasound is pervasive in everyday environments, appearing near ventilation systems, traffic, and industrial machinery,” says Schmaltz. Most of the time, we walk through it without a second thought. The question the team wanted to answer was whether walking through it was actually doing something to us, whether the frequency was registered somewhere below consciousness, somewhere we couldn’t readily name.

The experimental setup was deliberately ordinary. Thirty-six undergraduate students filed one at a time into isolated testing rooms and sat alone with a piece of music, either a calming instrumental or a horror-themed ambient track designed to provoke discomfort. Hidden subwoofers, including a 12-inch unit positioned in an adjacent hallway and a 16-inch speaker oriented toward the ceiling in a neighboring room, pumped infrasound at approximately 18 Hz into half those spaces. The participants had no idea. That last point turned out to be rather important. When the team ran the numbers, they found that participants couldn’t reliably identify whether infrasound had been present. Their guesses were, statistically speaking, no better than chance. And according to Schmaltz, participants’ beliefs about whether the infrasound was on had no detectable effect on their cortisol or mood. The physiological response didn’t care what the participants thought was happening. It just happened anyway.

What happened, specifically, was this: those exposed to infrasound reported higher irritability, lower interest in the music, and a tendency to rate the music as sadder, irrespective of whether it was the calming or the horror track. Cortisol levels, measured before and about 20 minutes after exposure, were also elevated. Kale Scatterty, the PhD student who led the work, notes that irritability and cortisol do tend to move together under ordinary stress, but adds that “infrasound exposure had effects on both outcomes that went beyond that natural relationship.” That distinction matters more than it might seem. Previous theories about infrasound and paranormal experience have often leaned on anxiety as the explanatory mechanism, the idea that low-frequency sound triggers a kind of free-floating dread that the mind then reaches for supernatural explanations to account for. The new data don’t really support that picture. Measures of anxiety didn’t budge significantly. What went up was irritability and disinterest, a kind of sour, low-grade aversion rather than fear. That’s perhaps a more honest description of how a lot of ghost stories actually feel in the telling: not screaming terror, but wrong atmosphere, a sense of unease that never quite crystallizes into something you can point at.

[…] The first new agreement affects Bluepoint Wind, a wind farm in the early stages of development off New York and New Jersey. The project was proposed by Global Infrastructure Partners, a part of asset manager BlackRock, and Ocean Winds, which is itself a joint venture between Engie and EDP Renewables, two European clean-energy firms. The second deal would cancel Golden State Wind, another early-stage venture off California’s central coast. Golden State Wind is a 50-50 partnership between the developers Ocean Winds and Reventus Power.

Both Bluepoint Wind and Golden State Wind agreed not to pursue any new offshore wind projects in the United States, although that pledge would not necessarily apply to the companies behind the ventures. Ocean Winds has also been developing another giant wind farm known as SouthCoast Wind, off Martha’s Vineyard, Mass., that is much further along in the planning and permitting process. That project is not affected by Monday’s announcement, although it has essentially been paused since Mr. Trump took office last year. […] It is also unclear how much the companies will actually invest in new fossil fuel infrastructure. In documents released this month, Interior revealed that it would count investments that TotalEnergies made before the deal toward its pledge, raising questions over whether the company had any obligations to make additional investments.

Technology tycoons Elon Musk and Sam Altman are poised to face off in a high-stakes trial revolving around the alleged betrayal, deceit and unbridled ambition that blurred the bickering billionaires’ once-shared vision for the development of artificial intelligence. The trial, which started Monday with jury selection, centers on the 2015 birth of ChatGPT maker OpenAI as a nonprofit startup primarily funded by Musk before evolving into a capitalistic venture now valued at $852 billion. The trial’s outcome could sway the balance of power in AI — breakthrough technology that is increasingly being feared as a potential job killer and an existential threat to humanity’s survival. Those perceived risks are among the reasons that Musk, the world’s richest person, cites for filing an August 2024 lawsuit that will now be decided by a jury and U.S. District Judge Yvonne Gonzalez Rogers in Oakland, California.

The civil lawsuit accuses Altman, OpenAI’s CEO, and his top lieutenant, Greg Brockman, of double-crossing Musk by straying from the San Francisco company’s founding mission to be an altruistic steward of a revolutionary technology. The lawsuit alleges they shifted into a moneymaking mode behind his back. OpenAI has brushed off Musk’s allegations as an unfounded case of sour grapes that’s aimed at undercutting its rapid growth and bolstering Musk’s own xAI, which he launched in 2023 as a competitor. Gonzalez Rogers questioned potential jurors Monday about their views on Musk, Altman and artificial intelligence. Some jurors said they had negative views of Musk, but most said they would still be able to treat him fairly and focus on the facts of the case. […] “Part of this is about whether a jury believes the people who will testify and whether they are credible,” Gonzalez Rogers said during a court hearing earlier this year while explaining why she believe the case merited a trial. The judge will make the final decision on the case, with the jury serving in an advisory role.

Researchers working with data from the Internet Archive have discovered that a third of websites created since 2022 are AI-generated. The team of researchers — which includes people from Stanford, the Imperial College London, and the Internet Archive — published their findings online in a paper titled "The Impact of AI-Generated Text on the Internet.” The research also found that all this AI-generated text is making the web more cheery and less verbose.
