In April, Paul Graham, the founder of the tech startup accelerator Y Combinator, sent a tweet in response to former YC president and current OpenAI CEO Sam Altman. Altman had just bid a public goodbye to GPT-4 on X, and Graham had a follow-up question.  “If you had [GPT-4’s model weights] etched on a piece of metal in the most compressed form,” Graham wrote, referring to the values that determine the model’s behavior, “how big would the piece of metal have to be? This is a mostly serious question. These models are history, and by default digital data evaporates.”  There is no question that OpenAI pulled off something historic with its release of ChatGPT 3.5 in 2022. It set in motion an AI arms race that has already changed the world in a number of ways and seems poised to have an even greater long-term effect than the short-term disruptions to things like education and employment that we are already beginning to see. How that turns out for humanity is something we are still reckoning with and may be for quite some time. But a pair of recent books both attempt to get their arms around it with accounts of what two leading technology journalists saw at the OpenAI revolution.  In Empire of AI: Dreams and Nightmares in Sam Altman’s OpenAI, Karen Hao tells the story of the company’s rise to power and its far-reaching impact all over the world. Meanwhile, The Optimist: Sam Altman, OpenAI, and the Race to Invent the Future, by the Wall Street Journal’s Keach Hagey, homes in more on Altman’s personal life, from his childhood through the present day, in order to tell the story of OpenAI. Both paint complex pictures and show Altman in particular as a brilliantly effective yet deeply flawed creature of Silicon Valley—someone capable of always getting what he wants, but often by manipulating others.  Hao, who was formerly a reporter with MIT Technology Review, began reporting on OpenAI while at this publication and remains an occasional contributor. One chapter of her book grew directly out of that reporting. And in fact, as Hao says in the acknowledgments of Empire of AI, some of her reporting for MIT Technology Review, a series on AI colonialism, “laid the groundwork for the thesis and, ultimately, the title of this book.” So you can take this as a kind of disclaimer that we are predisposed to look favorably on Hao’s work.  With that said, Empire of AI is a powerful work, bristling not only with great reporting but also with big ideas. This comes across in service to two main themes.  The first is simple: It is the story of ambition overriding ethics. The history of OpenAI as Hao tells it (and as Hagey does too) is very much a tale of a company that was founded on the idealistic desire to create a safety-focused artificial general intelligence but instead became more interested in winning. This is a story we’ve seen many times before in Big Tech. See Theranos, which was going to make diagnostics easier, or Uber, which was founded to break the cartel of “Big Taxi.” But the closest analogue might be Google, which went from “Don’t be evil” to (at least in the eyes of the courts) illegal monopolist. For that matter, consider how Google went from holding off on releasing its language model as a consumer product out of an abundance of caution to rushing a chatbot out the door to catch up with and beat OpenAI. In Silicon Valley, no matter what one’s original intent, it always comes back to winning.   The second theme is more complex and forms the book’s thesis about what Hao calls AI colonialism. The idea is that the large AI companies act like traditional empires, siphoning wealth from the bottom rungs of society in the forms of labor, creative works, raw materials, and the like to fuel their ambition and enrich those at the top of the ladder. “I’ve found only one metaphor that encapsulates the nature of what these AI power players are: empires,” she writes. “During the long era of European colonialism, empires seized and extracted resources that were not their own and exploited the labor of the people they subjugated to mine, cultivate, and refine those resources for the empires’ enrichment.” She goes on to chronicle her own growing disillusionment with the industry. “With increasing clarity,” she writes, “I realized that the very revolution promising to bring a better future was instead, for people on the margins of society, reviving the darkest remnants of the past.”  To document this, Hao steps away from her desk and goes out into the world to see the effects of this empire as it sprawls across the planet. She travels to Colombia to meet with data labelers tasked with teaching AI what various images show, one of whom she describes sprinting back to her apartment for the chance to make a few dollars. She documents how workers in Kenya who performed data-labeling content moderation for OpenAI came away traumatized by seeing so much disturbing material. In Chile she documents how the industry extracts precious resources—water, power, copper, lithium—to build out data centers.  She lands on the ways people are pushing back against the empire of AI across the world. Hao draws lessons from New Zealand, where Maori people are attempting to save their language using a small language model of their own making. Trained on volunteers’ voice recordings and running on just two graphics processing units, or GPUs, rather than the thousands employed by the likes of OpenAI, it’s meant to benefit the community, not exploit it.  Hao writes that she is not against AI. Rather: “What I reject is the dangerous notion that broad benefit from AI can only be derived from—indeed will ever emerge from—a vision of the technology that requires the complete capitulation of our privacy, our agency, and our worth, including the value of our labor and art, toward an ultimately imperial centralization project … [The New Zealand model] shows us another way. It imagines how AI could be exactly the opposite. Models can be small and task-specific, their training data contained and knowable, ridding the incentives for widespread exploitative and psychologically harmful labor practices and the all-consuming extractivism of producing and running massive supercomputers.”  Hagey’s book is more squarely focused on Altman’s ambition, which she traces back to his childhood. Yet interestingly, she also  zeroes in on the OpenAI CEO’s attempt to create an empire. Indeed, “Altman’s departure from YC had not slowed his civilization-building ambitions,” Hagey writes. She goes on to chronicle how Altman, who had previously mulled a run for governor of California, set up experiments with income distribution via Tools for Humanity, the parent company of Worldcoin. She quotes Altman saying of it, “I thought it would be interesting to see … just how far technology could accomplish some of the goals that used to be done by nation-states.”  Overall, The Optimist is the more straightforward business biography of the two. Hagey has packed it full with scoops and insights and behind-the-scenes intrigue. It is immensely readable as a result, especially in the second half, when OpenAI really takes over the story. Hagey also seems to have been given far more access to Altman and his inner circles, personal and professional, than Hao did, and that allows for a fuller telling of the CEO’s story in places. For example, both writers cover the tragic story of Altman’s sister Annie, her estrangement from the family, and her accusations in particular about suffering sexual abuse at the hands of Sam (something he and the rest of the Altman family vehemently deny). Hagey’s telling provides a more nuanced picture of the situation, with more insight into family dynamics.  Hagey concludes by describing Altman’s reckoning with his role in the long arc of human history and what it will mean to create a “superintelligence.” His place in that sweep is something that clearly has consumed the CEO’s thoughts. When Paul Graham asked about preserving GPT-4, for example, Altman had a response at the ready. He replied that the company had already considered this, and that the sheet of metal would need to be 100 meters square.

Warning: contains finale spoilers for Dept. Q See it? Blink and you won’t have, but it was there for a good half second: a smile on the face of DCI Carl Morck. It’s a rare enough occurrence across nine episodes of this Netflix crime drama to make it worthy of note. Matthew Goode’s irascible detective frowned, scowled and spitted out sarcasm through his new department’s search for missing prosecutor Merritt Lingard, until the show’s very last moment, when he smiled. He’d earned it. Three months earlier, Morck’s cold case unit had rescued Lingard and used dirt dug up during the investigation to blackmail the Lord Advocate (the most senior law officer in Scotland) into a funding hike, a new work car, and fast-tracked DI status for Syrian copper and calmly proficient muscle Akram Salim. And now, Morck’s partner Hardy, formerly thought to have permanently lost the use of his legs after they were both shot in the line of duty, was walking again. It was a happy ending, or at least as happy as things get in a dank Edinburgh basement filled with unsolved case files detailing terrible crimes. With major Dept. Q finale spoilers, let’s dig into the revelations about Merritt’s kidnappers, what we learned about the Leith Park shooting, and more. Who Kidnapped Merritt Lingard and Why? Merritt’s kidnappers were Lyle and Ailsa Jennings, respectively the younger brother and mother of Harry Jennings, Merritt’s boyfriend as a teenager. She was being held on their property on her childhood island home of Mhòr, in a pressurised hyperbaric chamber inside a condemned building that was formerly part of Ailsa’s husband’s oceanography business Shorebird Ocean Systems – the logo for which was the cormorant symbol identified by Merritt’s brother William as on the hat of her stalker and kidnapper. Ailsa was a twisted and abusive mother to Harry and Lyle, as well as a murderer who killed her husband by burning the house down by flicking lighted matches at him while he slept. As a result, Lyle grew up to be a violent psychopath whose teenage crimes were covered up by the family and by the island’s police officer John Cunningham. John knew that Lyle was responsible for Merritt’s disappearance, but didn’t know she was still alive, having believed Lyle when he lied that Merritt had died by falling off the ferry from the mainland, just like Lyle’s brother Harry had done years earlier. Lyle and Ailsa blamed Merritt for Harry’s death because he jumped from the ferry while being pursued by John, who was chasing him because he was suspected of having severely beaten Merritt’s brother William into a coma during an interrupted robbery of the Lingard home. The robbery plan had been seeded by Merritt to steal her mother’s jewellery from her alcoholic father in order to sell for money to run away from home. In fact, Lyle was the one who had attacked William, being unhinged and thinking that he was protecting his brother. Harry and Ailsa covered up Lyle’s guilt and before his death, Harry took the blame. Lyle Jennings, Godhaven, and Sam Haig Lyle, who had a history of stalking, breaking-and-entering, and animal murder, spent time in youth psychiatric facility Godhaven, where he stalked another patient named Sam Haig. The pair fought, and Sam injured Lyle’s eye so severely that it was left permanently discoloured. Years later as an adult who had become an investigative journalist with no online presence, Sam sought Lyle out to apologise for the injury and invite him to come climbing at his favourite spot. Lyle used the information he had on Sam to assume his identity and stalk Merritt Lingard, who didn’t recognise him as an adult. He pretended to be investigating corruption at Merritt’s workplace, and targeted her, eventually starting a sexual relationship still pretending to be Sam. When Merritt told Lyle-as-Sam that she was leaving to go to Mhòr on the 10am ferry the next day, Lyle used that information to kidnap her during the crossing. Merritt’s brother William, who had been unable to speak since his teenage coma, had spotted Lyle on the ferry and because of Lyle’s distinctive hat, recognised him as the man who’d been stalking their house. He tried to communicate this to Merritt by throwing his own hat, and then struck her when he became afraid. It was when Merritt went to retrieve William’s hat that she was taken. Join our mailing list Get the best of Den of Geek delivered right to your inbox! Two days after Lyle kidnapped Merritt, he returned to the mainland to tie up loose ends and kill the real Sam Haig. He lured Sam to a remote spot, beat him to death, staged his corpse to look as though he had been climbing, and threw it off a cliff. Eventually, Morck and co. worked out that somebody else was pretending to be Sam Haig when they had evidence that Merritt had been with “Sam” at a hotel at the same time that the real Sam was having an affair with his friend’s wife at a different hotel. What Happened to Lyle and Ailsa Jennings? Merritt’s kidnappers both died – Ailsa by her own hand as she shot herself in her car before being taken into custody by the police, and Lyle by Akram’s hand, or rather, his trigger finger. After Lyle shot buckshot into Morck’s shoulder, Akram threw a knife at him, disarmed and shot him. Previously, Lyle had brutally killed Constable John Cunningham with a hammer when he learned that Merritt was still alive. Mark Bonnar’s character Stephen Burns had disallowed the appearance of a key witness in the Graham Finch murder trial after Burns’ daughter was run off the road by one of Finch’s goons as an intimidation tactic. Prisoner Kirsty Atkins was willing to testify that she had previously met Finch’s now-dead wife at a shelter for survivors of domestic violence, and that Finch routinely hit her. Because Burns wouldn’t allow her testimony, Finch was acquitted of his wife’s murder despite clearly having been guilty of it. Perhaps he also passed on the information about Kirsty Atkins to Finch’s lawyer, which led to Kirsty being viciously attacked and partially blinded in prison on Finch’s orders to keep her quiet. Who Is the Leith Park Shooter? We still don’t know who shot PC Anderson dead, and attempted to shoot Morck and Hardy dead at the Leith Park flat. If we can take the contents of Morck’s dream as gospel, then the shooting was done on the orders of Leith Park criminal kingpin Eugene Errington, whom we’ve yet to meet. According to Morck’s dream, in which he shot Errington’s muscle Charlie Bell in the head, Errington has a baby with Caroline Kerr – the witness who was intimidated into withdrawing her statement about the shooting. We also know, or at least have a pretty good idea, that PC Anderson was a corrupt officer working for Errington, and that he may even have been the one to stab the victim – thought to have been a police informant – in the head. Anderson was a top recruit pretending to be a klutz, Morck realised, in order to cover up the fact that his fingerprints were all over the victim’s flat. He also lied about being at the flat for a routine welfare check after being alerted by the victim’s daughter – that was a quick-thinking ruse to explain his presence when Morck and Hardy showed up there unexpectedly. The last we saw of the Leith Park case, Moira looked to be taking it away from its lead investigator and possibly closing it, unsolved, which may point to her also having been compromised by Errington. As Hardy was one of the shooting’s victims, surely that can’t be the case file that she gave to Hardy to investigate without Morck in the season’s closing moments? Dept. Q is streaming now on Netflix.

The probability of any American having dementia in their lifetime may be far greater than previously thought. For instance, a 2025 study that tracked a large sample of American adults across more than three decades found that their average likelihood of developing dementia between ages 55 to 95 was 42%, and that figure was even higher among women, Black adults and those with genetic risk. Now, a great deal of attention is being paid to how to stave off cognitive decline in the aging American population. But what is often missing from this conversation is the role that chronic stress can play in how well people age from a cognitive standpoint, as well as everybody’s risk for dementia. We are professors at Penn State in the Center for Healthy Aging, with expertise in health psychology and neuropsychology. We study the pathways by which chronic psychological stress influences the risk of dementia and how it influences the ability to stay healthy as people age. Recent research shows that Americans who are currently middle-aged or older report experiencing more frequent stressful events than previous generations. A key driver behind this increase appears to be rising economic and job insecurity, especially in the wake of the 2007-2009 Great Recession and ongoing shifts in the labor market. Many people stay in the workforce longer due to financial necessity, as Americans are living longer and face greater challenges covering basic expenses in later life. Therefore, it may be more important than ever to understand the pathways by which stress influences cognitive aging. Social isolation and stress Although everyone experiences some stress in daily life, some people experience stress that is more intense, persistent or prolonged. It is this relatively chronic stress that is most consistently linked with poorer health. In a recent review paper, our team summarized how chronic stress is a hidden but powerful factor underlying cognitive aging, or the speed at which your cognitive performance slows down with age. It is hard to overstate the impact of stress on your cognitive health as you age. This is in part because your psychological, behavioral and biological responses to everyday stressful events are closely intertwined, and each can amplify and interact with the other. For instance, living alone can be stressful—particularly for older adults—and being isolated makes it more difficult to live a healthy lifestyle, as well as to detect and get help for signs of cognitive decline. Moreover, stressful experiences—and your reactions to them—can make it harder to sleep well and to engage in other healthy behaviors, like getting enough exercise and maintaining a healthy diet. In turn, insufficient sleep and a lack of physical activity can make it harder to cope with stressful experiences. Stress is often missing from dementia prevention efforts A robust body of research highlights the importance of at least 14 different factors that relate to your risk of Alzheimer’s disease, a common and devastating form of dementia and other forms of dementia. Although some of these factors may be outside of your control, such as diabetes or depression, many of these factors involve things that people do, such as physical activity, healthy eating and social engagement. What is less well-recognized is that chronic stress is intimately interwoven with all of these factors that relate to dementia risk. Our work and research by others that we reviewed in our recent paper demonstrate that chronic stress can affect brain function and physiology, influence mood and make it harder to maintain healthy habits. Yet, dementia prevention efforts rarely address stress. Avoiding stressful events and difficult life circumstances is typically not an option. Where and how you live and work plays a major role in how much stress you experience. For example, people with lower incomes, less education or those living in disadvantaged neighborhoods often face more frequent stress and have fewer forms of support—such as nearby clinics, access to healthy food, reliable transportation or safe places to exercise or socialize—to help them manage the challenges of aging As shown in recent work on brain health in rural and underserved communities, these conditions can shape whether people have the chance to stay healthy as they age. Over time, the effects of stress tend to build up, wearing down the body’s systems and shaping long-term emotional and social habits. Lifestyle changes to manage stress and lessen dementia risk The good news is that there are multiple things that can be done to slow or prevent dementia, and our review suggests that these can be enhanced if the role of stress is better understood. Whether you are a young, midlife or an older adult, it is not too early or too late to address the implications of stress on brain health and aging. Here are a few ways you can take direct actions to help manage your level of stress: Follow lifestyle behaviors that can improve healthy aging. These include: following a healthy diet, engaging in physical activity and getting enough sleep. Even small changes in these domains can make a big difference. Prioritize your mental health and well-being to the extent you can. Things as simple as talking about your worries, asking for support from friends and family and going outside regularly can be immensely valuable. If your doctor says that you or someone you care about should follow a new health care regimen, or suggests there are signs of cognitive impairment, ask them what support or advice they have for managing related stress. If you or a loved one feel socially isolated, consider how small shifts could make a difference. For instance, research suggests that adding just one extra interaction a day—even if it’s a text message or a brief phone call—can be helpful, and that even interactions with people you don’t know well, such as at a coffee shop or doctor’s office, can have meaningful benefits. Walkable neighborhoods, lifelong learning A 2025 study identified stress as one of 17 overlapping factors that affect the odds of developing any brain disease, including stroke, late-life depression and dementia. This work suggests that addressing stress and overlapping issues such as loneliness may have additional health benefits as well. However, not all individuals or families are able to make big changes on their own. Research suggests that community-level and workplace interventions can reduce the risk of dementia. For example, safe and walkable neighborhoods and opportunities for social connection and lifelong learning—such as through community classes and events—have the potential to reduce stress and promote brain health. Importantly, researchers have estimated that even a modest delay in disease onset of Alzheimer’s would save hundreds of thousands of dollars for every American affected. Thus, providing incentives to companies who offer stress management resources could ultimately save money as well as help people age more healthfully. In addition, stress related to the stigma around mental health and aging can discourage people from seeking support that would benefit them. Even just thinking about your risk of dementia can be stressful in itself. Things can be done about this, too. For instance, normalizing the use of hearing aids and integrating reports of perceived memory and mental health issues into routine primary care and workplace wellness programs could encourage people to engage with preventive services earlier. Although research on potential biomedical treatments is ongoing and important, there is currently no cure for Alzheimer’s disease. However, if interventions aimed at reducing stress were prioritized in guidelines for dementia prevention, the benefits could be far-reaching, resulting in both delayed disease onset and improved quality of life for millions of people.

Peter David, the highly regarded novelist and writer of comics like The Incredible Hulk, Young Justice, and X-Factor, has died at 68. The news was confirmed by David's friend and colleague Keith R.A. DeCandido via Facebook.David enjoyed a long and prolific career at Marvel and DC over several decades. He may be best remembered for his 12-year run on Marvel's The Incredible Hulk series, a sprawling saga that redefined the relationship between Bruce Banner and his alter ego and earned David and artist Dale Keown an Eisner Award in 1992. As much as Frank Miller is viewed as the definitive Daredevil writer/artist and Chris Claremont the definitive X-Men writer, David is widely regarded as the most important and influential Hulk writer of all time. Art by George Perez. (Image Credit: Marvel)David is also well known for co-creating Spider-Man 2099 and for his two runs on X-Factor. David's original X-Factor run saw the team, which was originally a reunion of the original five X-Men, remade into a government-sanctioned mutant strike force. His second X-Factor run again reinvented the team, this time as a detective agency led by Madrox the Multiple Man. At DC, David enjoyed successful and influential stints on books like Aquaman, Supergirl, and Young Justice. David also regularly worked on the Star Trek franchise in both comic book and prose form, with his best-known Trek work being the 1994 novel Q-Squared. Outside of books and comics, David worked on television shows like Babylon 5, Young Justice, and Ben 10: Alien Force and wrote video games like Shadow Complex and Spider-Man: Edge of Time.A Visual History of HulkDavid suffered from poor health in recent years, beginning with a stroke in 2012.

Apple's big 2025 software reveal is nearly upon us. On June 9, the Worldwide Developers' Conference (WWDC) keynote will showcase the changes coming with its 2025 software. That includes — deep breath — iOS 19, iPadOS 19, macOS 16, watchOS 12, tvOS 19 and visionOS 3. Leaks suggest this year will be a biggie. In addition to the requisite Craig Federighi gags, expect a significant visual overhaul — one of Apple's biggest ever — and (shocker) new Apple Intelligence features. Visual redesign The company is reportedly set to unveil a platform-wide visual overhaul. The revamp is said to be a dramatic change, drawing inspiration from Apple's mixed reality headset. Apple According to Front Page Tech's Jon Prosser, that may even include (nearly) round icons on the home screen and in Control Center. He also noted subtler changes, like a redesigned tab view within apps and the search box in Messages being moved to the bottom of the screen. One of Apple's core goals with the new software is to unify the design language of its operating systems. The idea is to make it less visually jarring to hop between devices. If executed well, jumping from iPhone to iPad to Mac (and so on) will feel like touring different flavors of the same OS. Apple's last big macOS makeover was with 2020's Big Sur. For the iPhone's software, you have to go all the way back to 2013. That's when iOS 7 kicked skeuomorphic design to the curb, replacing it with a flat, minimalistic look. Minus some iterative changes, it's still the UI you see today. The iPad goes to work Nathan Ingraham for Engadget Could 2025 be the year the iPad Pro starts to feel… Pro? The high-end versions of Apple's tablet have been more than capable on a hardware level for generations. (Especially when they switched to M-series chips.) But the software has held it back. That's presumably because the company doesn't want to cannibalize Mac sales. After all, if the iPad Pro can truly replace a laptop, then fewer people would buy both. The bad news for those wanting a full-on Mac experience: The iPad won't switch to macOS. The good news: iPadOS may get much more Mac-like. This year's update will reportedly focus on productivity, featuring improved multitasking and app window management. It's not that Apple hasn't inched the iPad's software in that direction. It incrementally did so with Stage Manager in iPadOS 16. The year before, it added the multitasking menu at the top of app windows. But for many, those tweaks fell far short of the full-on productivity overhaul they craved. Will it be enough this time? Bloomberg's Mark Gurman thinks it will "likely go far enough" for most power users. (Is that a "Hallelujah!" I hear?) Apple Intelligence Apple Even if leaks hadn't already suggested as much, this one would be a no-brainer. After all, AI has been every tech company's obsession since ChatGPT took the world by storm over two years ago. Expect a healthy portion of the keynote to be devoted to Apple's AI advances. These will reportedly include improvements to existing features and a few new ones. Siri Remember when Apple promised a more personalized Siri at last year's conference? The one that many wished would come ahead of the visual overhaul? Well, we're still waiting on that. The last official update we heard was in March, when the company told Daring Fireball, "It's going to take us longer than we thought." (Oops!) Apple expects the new Siri features to arrive "in the coming year," a clear-as-mud description if ever there was one. A report from The Information last month hinted that the upgraded Siri was nowhere near ready. The 2024 demo, where Siri condensed minutes of multi-app planning into mere seconds, reportedly came as a surprise to team members working on Siri. (Never an encouraging sign.) Apple Separate reporting this month from Bloomberg sheds a bit more light, adding that we probably won't hear much about those Siri upgrades at WWDC 2025. The publication described those updates as being months away from shipping. The company is also reportedly separating its Apple Intelligence and Siri marketing. The logic behind this is that users are so fed up with Apple's assistant that it's hurting Apple's AI push. The company's 2024 presentation was undoubtedly impressive. It showed a more context-sensitive Siri that better understands what you're doing. It pulled info from various apps and spliced them together in a seamless flow. It recorded a specific type of video in a third-party app. It shared a meeting summary via email with a teammate. And it found missing information the user remembered reading... somewhere. It even controlled system settings and explained them when needed. The bottom line: If or when Apple pulls off what it promised last year, that's big news for Siri. But don't hold your breath for it to show up at WWDC 2025. According to Bloomberg, the Siri updates we do see will be much subtler. These would include adding the option to use Gemini instead of ChatGPT with the assistant. AI battery management Apple Another iOS 19 scoop points to an Apple Intelligence feature that's easy to get behind. A new AI-powered battery management mode will reportedly analyze how you use your phone. It can then use that to make power-saving adjustments on the fly. If it works well, that could be pretty nifty. It may also be a key ingredient to a new device: the "iPhone Air." Whatever Apple calls it, the rumored ultra-slim handset is expected to join Apple's lineup this year. Without this feature, the phone's smaller battery might struggle to make it through a typical day. (According to Gurman, it would last several hours less than Apple's other iPhones.) But with the AI battery feature activated, the svelte iPhone could become more practical. Will we see this slim-jim iPhone at WWDC? Well, let's say you have as good a chance of Valve randomly showing up to announce Half Life 3 at Apple's conference. First, the svelte handset is expected to be part of the iPhone 17 lineup, which typically arrives around September. Second, Apple hasn't unveiled a new iPhone at WWDC since Steve Jobs showed off the iPhone 4 in 2010. So, in short, nope. Virtual health coach Apple Apple is reportedly working on a virtual health coach. Allegedly codenamed Project Mulberry, the AI feature would pair a refreshed Health app with an AI-powered coach. Bloomberg says the feature would, to some degree, give you advice you'd usually seek from a doctor. The virtual coach would collect data from your Apple devices and use AI to provide personalized health advice, chatbot-style. Apple is reportedly training the AI agent with data from company physicians. Meanwhile, outside experts would shoot educational videos. In March, Bloomberg's Gurman said the virtual coach could arrive as early as iOS 19.4, which wouldn't likely come until early to mid-2026. But a quick aside in a report this month from Gurman and Drake Bennett mentioned that it could be a point of focus at WWDC. Hair Force One Apple It wouldn't be an Apple keynote without some wacky Craig Federighi hijinks. Last year, Apple's software lead strapped on a hair-shaped helmet and skydived into Apple Park. At previous events, he showed off his parkour skills, summoned an iPad like he's a Jedi and jammed out on a three-necked guitar. Say what you will about "Hair Force One." Federighi knows how to sell a sight gag. (With maybe just a teensy bit of help from Apple's visual effects artists.) Betas and release dates Following Apple's typical schedule, you can expect the first developer betas to arrive after the conference ends. (Likely the same day!) Public betas would follow early this summer. And you can expect the final versions of iOS 19, iPadOS 19, macOS 16 and so on to arrive alongside new iPhones this fall.This article originally appeared on Engadget at https://www.engadget.com/mobile/smartphones/what-to-expect-at-wwdc-2025-a-new-look-apple-intelligence-and-more-210051144.html?src=rss

Hello and welcome to Modern CEO! I’m Stephanie Mehta, CEO and chief content officer of Mansueto Ventures. Each week this newsletter explores inclusive approaches to leadership drawn from conversations with executives and entrepreneurs, and from the pages of Inc. and Fast Company. If you received this newsletter from a friend, you can sign up to get it yourself every Monday morning. Summer officially starts in a few weeks, but I’ve already ordered and preordered the books that will keep me company on airplanes and trips to the beach. The first Modern CEO reading list was heavy on buzzworthy titles. Last year’s edition was a bit more dutiful, highlighting three works that explored the complexities of capitalism. This year, I’m diving into the lives of the ultrarich, whose impact on culture, society, and policy continues to rise. The Haves and the Have-Yachts: Dispatches on the Ultrarich by Evan Osnos Thanks in part to social media, consumption—of luxury goods, five-star resorts, rare wines, and the like—is increasingly conspicuous. One place where the ultrarich can avoid prying eyes? Aboard their superyachts. As Evan Osnos, a staff writer and podcast host at The New Yorker, writes of such floating mansions: “These shrines to excess capital exist in a conditional state of visibility: they are meant to be unmistakable to a slender stratum of society—and all but unseen by everyone else.” Osnos’s collection of essays promises to shed light on the excesses but also on how the rich amass and keep their wealth and the power that it affords. Personal History: A Memoir by Katharine Graham and Buffett: The Making of an American Capitalist by Roger Lowenstein One of the biggest business stories of the year—Warren Buffett’s announcement that he will step down as CEO of Berkshire Hathaway—and the ongoing struggles of The Washington Post under Jeff Bezos (a superyacht owner), are prompting me to reread two great books on my bookshelf. Personal History is Graham’s candid memoir of the personal and professional hurdles she had to overcome en route to becoming CEO of The Washington Post Company and one of the most admired executives in media. Lowenstein’s masterful portrait of Buffett is part biography, part investing tutorial. Graham and Buffett were longtime friends, and Lowenstein seems to credit Graham with leavening some of Buffett’s thrifty instincts. Stories of Buffett’s frugality—his primary residence is a home he bought in Omaha in 1958 for $31,500—will surely be a good palate cleanser after the Osnos book. Empire of AI: Dreams and Nightmares in Sam Altman’s OpenAI by Karen Hao Hao, an Atlantic contributor, is one of the leading journalists covering artificial intelligence (AI), and her book promises to be an unflinching look at the potential and perils of OpenAI CEO Sam Altman’s ambitions for generative AI, which seem to mirror the “move fast and break things” ethos of many tech companies. Luckily for readers, Hao seems willing to explore the unintended consequences of unfettered AI expansion, including the environmental impacts of water- and energy-hungry data centers. So Far Gone by Jess Walter Walter’s latest book—my one fiction pick—has many of the things I love in novel: a road trip, multigenerational conflict, and a gruff former journalist as the protagonist. In So Far Gone, Rhys Kinnick sets off to rescue his daughter and grandchildren from a radical militia group. It’s a world Walter knows well: As a journalist for the Spokane, Washington Spokesman-Review, Walter covered the 1992 standoff at Ruby Ridge in Northern Idaho, which is credited with fueling the anti-government militia movement. Challenging stuff, but an early review from Ann Patchett confirms why I love Walter’s writing: “Jess Walter managed to build such a warm, funny, loving novel out of so many horrible parts.” What are you reading this summer? What’s on your summer reading list? Please send the name, author, and a sentence or two about why you’d recommend it to modern leaders to stephaniemehta@mansueto.com.

May 23, 20255 min readNOAA Says It’s Ready for Hurricane Season, but Weather Experts Are WorriedAs hurricane season approaches, thousands of weather and disaster experts have raised concerns about NOAA and NWS budget cuts and staffing shortagesBy Chelsea Harvey & E&E News The remnants of Hurricane Helene begin to dissipate over the United States in this NOAA satellite from Sept. 27, 2024. Space Image Archive/Alamy Stock PhotoCLIMATEWIRE | The National Oceanic and Atmospheric Administration insists it’s ready for the above-average hurricane season that meteorologists expect this summer.But scientists across the country are sounding the alarm about personnel shortages and budget cuts, which they say could strain the agency’s resources and risk burnout among its staff.The tension was on display Thursday as NOAA officials announced the agency’s annual Atlantic hurricane season outlook.On supporting science journalismIf you're enjoying this article, consider supporting our award-winning journalism by subscribing. By purchasing a subscription you are helping to ensure the future of impactful stories about the discoveries and ideas shaping our world today.This year’s projection suggests a 60 percent chance of an above-average season, with anywhere from 13 to 19 named storms and three to five major hurricanes. That’s compared with the long term average of 14 named storms and three major hurricanes in a typical season.NOAA hosted this year’s announcement in Gretna, Louisiana, just outside New Orleans, in a nod to the upcoming 20th anniversary of Hurricane Katrina, which devastated the city in 2005. The agency has made significant strides in hurricane forecasts and warnings over the past two decades, officials said — including life-saving improvements in hurricane track and intensity predictions and new forms of modeling, radar and observation technology.“These improvements and collaborative efforts demonstrate that NOAA is now more prepared than ever for what hurricane season may bring,” said NOAA chief of staff Laura Grimm.But reporters at the briefing pushed back on that certainty, noting that recent cuts have eroded some of the agency’s observation capabilities and left dozens of local National Weather Service offices understaffed.Thousands of scientists have raised the same concerns over the past few months, as the Trump administration has reduced NOAA staff by more than 2,200 people, or around 20 percent of its former workforce. The administration also has proposed a plan to dramatically reorganize the agency and effectively eliminate its climate research operations.The National Weather Service alone has lost around 550 staff members since January, leaving the agency scrambling to fill at least 155 key job openings at regional offices around the country; some include top positions such as meteorologist-in-charge.At least 3,300 scientists have signed an open letter to Commerce Secretary Howard Lutnick, who leads the department that oversees NOAA, warning that cuts to the agency could have “dire consequences for American lives and livelihoods.”And earlier this month, five former National Weather Service directors published an open letter warning that the recent cuts mean NWS staff members face “an impossible task” when it comes to maintaining their usual level of service.Volunteers work to remove debris and mud from a flooded home on Edwards Avenue in Beacon Village neighborhood after a catastrophic flooding caused from Hurricane Helene caused the Swannanoa river to swell to record levels October 5, 2024 in Swannanoa, North Carolina.Steve Exum/Getty Images“Some forecast offices will be so short-staffed that they may be forced to go to part time services,” the letter warned. “Our worst nightmare is that weather forecast offices will be so understaffed that there will be needless loss of life.”NOAA officials sidestepped these worries at Thursday's presentation, insisting the National Hurricane Center’s headquarters is fully staffed and prepared for the upcoming season.“We had some folks go,” said National Weather Service director Ken Graham. “But we’re gonna make sure that we have everything that we have on the front lines. Every warning’s gonna go out.”It remains unclear how the agency plans to address the dozens of vacancies at local offices across the country, including some hurricane-prone areas along the East and Gulf coasts. Lawmakers have reported that NOAA managers are encouraging staff members to pursue reassignments to understaffed offices, while the former NWS directors noted that staff members have been known to sleep in their offices to avoid gaps in coverage.That scenario played out recently at a regional office in Jackson, Kentucky, that is so understaffed that it’s no longer able to regularly operate overnight. When deadly tornadoes struck the region earlier this month, meteorologists there made the decision to call all hands on deck to staff the overnight shift and ensure the quality of forecasts and warnings, CNN reported.But experts say it’s an unsustainable system, which could lead to burnout this summer when disasters like hurricanes, floods and wildfires are at their peak.“It’s not sustainable if we have multiple high-impact weather events,” said Brian LaMarre, a former meteorologist-in-charge at the National Weather Service’s Tampa Bay Area office and founder of the weather consulting service Inspire Weather. “It doesn't matter if we’re forecasting above normal or below normal, it only takes that one storm to truly make a significant impact.”Risks rise with global temperaturesMeanwhile, Atlantic hurricane seasons are expected to grow more intense as global temperatures rise.This year’s projections for an active season are partly linked to above-average ocean temperatures, which help fuel the formation of tropical cyclones. This year’s temperatures aren’t as warm as they were the past two seasons, when ocean waters broke daily records for more than a year. But they’re still warm enough to cause concern.Natural climate cycles play a part in each year’s hurricane outlook. Every few years, the planet shifts between El Niño and La Niña events, which cause temperatures in the Pacific Ocean to grow periodically warmer and cooler. These events influence weather and climate patterns around the globe, with El Niño typically associated with below-average Atlantic hurricane activity and La Niña contributing to more active seasons.This year, the planet is in a neutral phase, meaning Pacific Ocean temperatures are close to average. With no El Niño event to hinder the formation of tropical cyclones, warmer-than-average Atlantic temperatures are likely to fuel an active season.Climate change is partly to blame. Scientists warn that greenhouse gas emissions and continued global warming are gradually raising sea surface temperatures across much of the world. Studies suggest that hurricanes are intensifying faster and growing stronger as a result, leading to a greater risk of major storms striking the United States.Last year’s Atlantic hurricane season was a stark reminder of the growing dangers.Hurricane Beryl smashed records in July as the earliest Atlantic hurricane to achieve a Category 4, before eventually expanding to a Category 5. Hurricane Milton rapidly intensified into the season’s second Category 5 storm — and although it weakened to a Category 3 before making landfall, it dropped historic rainfall and spawned dozens of tornadoes along the Florida coast.And Hurricane Helene made history as an unusually large and fast-moving storm, hitting Florida as a Category 4 and barreling inland, where it carved a path of destruction through Appalachia. It became the deadliest storm to strike the mainland U.S. since Hurricane Katrina.Reprinted from E&E News with permission from POLITICO, LLC. Copyright 2025.

Phoenix House / HGA.StudioSave this picture!© Andy MacPhersonHouses•Byron Bay, Australia Architects: HGA.Studio Area Area of this architecture project Area:  140 m² Year Completion year of this architecture project Year:  2020 Photographs Photographs:Andy MacPherson Lead Architects: Harley Graham More SpecsLess Specs Save this picture! Text description provided by the architects. Phoenix House is a profoundly personal endeavor, born from the restoration of an early 1900s Queenslander purchased in Brisbane, Australia. Initially, I had various plans for the property, but life's unexpected twists transformed it into a new home for me and my two children. While stored in the cane fields near Ballina, the house endured brutal southerly storms. When I visited, the tarps were gone, the structure was waterlogged, and the side veranda had collapsed into a heap of hardwood.Save this picture!Overwhelmed, I broke down. The rot-riddled house seemed beyond saving, yet I had no choice but to press on. This became my 'Phoenix moment'—a symbol of personal renewal. Friends, colleagues, engineers, landscape designers, and contractors rallied around the vision, inspired by its metaphor of rebirth.Save this picture!Our studio approached the house like a 'remix album.' We stripped it to its core, cataloged the salvageable pieces, and reimagined their use in a sustainable, puzzle-like assembly. Old casement windows were repurposed as the kitchen splashback, rich teak decking adorned bedroom walls, and other elements were creatively reconfigured.Save this picture!Save this picture!Save this picture!Located in Byron's historic precinct, near my grandparents' original fisherman's cottage, the site faces sports fields to the north, with native vegetation and the bay beyond. The house sits 1600mm above ground, accommodating bike storage, twenty surfboards, and sustainability systems like water tanks, solar batteries, and heat pumps. This elevation, paired with broad timber steps, turns the front deck into a 'stage' overlooking the park. The veranda serves as a bridge between home and community, fostering connection.Save this picture!The design prioritizes simplicity within its 140m² footprint, creating a three-bedroom home that feels expansive. A striking skylight anchors the living area, while a 3x3 m sliding door frames park views, enhancing openness. The house feels like a finely crafted piece of joinery, with a restrained material palette. A robust blockwork pool and native-filled planters ground the lightweight structure. Next to it, a 45m², 2.8 m-wide studio with soaring 4m ceilings serves as a prototype for future 'tiny homes,' feeling surprisingly spacious.Save this picture!Phoenix House embodies the balance between Byron's heritage and its evolving lifestyle. It honors the past while offering a model for sensitive, sustainable development as Australia's coastal towns face growing pressures.Save this picture!

An artist’s impression of Earth’s quasi-satellite Kamo`oalewa, the first destination of the Tianwen-2 missionAddy Graham/University of Arizona Final preparations are under way for China to launch an uncrewed craft to visit both an asteroid and a comet, in the hope of learning more about the space rocks in our solar system. The Tianwen-2 mission by the China National Space Administration (CNSA) will collect a 100-gram sample from the asteroid Kamoʻoalewa and return it to Earth. After dropping off the sample, the probe will use our planet’s gravity as a slingshot Advertisement The mission is due to launch from the Xichang Satellite Launch Center in Sichuan province on 29 May. It won’t be the first to return samples of asteroids to Earth, as both NASA’s OSIRIS-REx and JAXA’s Hayabusa missions have already done that. But it will be China’s first mission to an asteroid involving the return of a rock sample, and it is likely to be the first mission to a unique type of body called a quasi-satellite. Quasi-satellites like Kamoʻoalewa don’t strictly orbit Earth, but travel in a similar orbit to us around the sun, swinging elliptically around our planet as they do so. This unusual situation has led scientists to suspect that this particular one is a chunk of the moon ejected millions of years ago by an asteroid impact. On the other hand, 311P/PanSTARRS has an asteroid-like orbit – spinning around our sun in the asteroid belt between Mars and Jupiter – but with an appearance more like a comet because it has tails. These are suspected of being bits of dust and rubble flung out from its spinning body. Voyage across the galaxy and beyond with our space newsletter every month. Sign up to newsletter The CNSA has previously said that 311P/PanSTARRS is a “living fossil”, making it useful for studying the early material composition, formation process and evolutionary history of the solar system. And Tianwen-2 will provide scientists with a better understanding of both Kamoʻoalewa and 311P/PanSTARRS. However, the results won’t come quickly: the craft is due to reach 311P/PanSTARRS in 2034, and even the Kamoʻoalewa sample is expected to return to Earth only in late 2027. Exactly how much the CNSA will share about the discoveries is also unclear. Leah-Nani Alconcel at the University of Birmingham, UK, says the mission’s outline is known, and one likely goal is to study the differences between the asteroid and the comet to gain a deeper understanding of the range of bodies in our solar system, but precise details haven’t been forthcoming. Alconcel’s previous experience working with the CNSA on the Double Star satellite leads her to suspect that the agency will hold on to the resulting scientific data tightly. “It was extremely difficult to negotiate [with the CNSA],” says Alconcel.
”Once they kind of had some information from us, they were not very keen to reciprocate. There will not be a public repository of this data, I don’t think.” She says that the mission is daring, as Kamoʻoalewa is spinning, which will make landing harder. Navigation algorithms are likely to demand such powerful computers that images and sensor readings will be sent back to Earth for computation. “If we were to always pick lovely, cooperative objects, we wouldn’t learn a lot,” she says. “There’s a lot that could potentially go wrong.” The CNSA didn’t respond to New Scientist‘s request for interview.
