Being a night owl can be bad for your heart. That may sound surprising but a large study found people who are more active late at night — when most of the population is winding down or already asleep — have poorer overall heart health than the average person. “It is not like, that, night owls are doomed,” said research fellow Sina Kianersi of Brigham and Women’s Hospital and Harvard Medical School, who led the study. “The challenge is the mismatch between your internal clock and typical daily schedules” that makes it harder to follow heart-healthy behaviors. And that’s fixable, added Kianersi, who describes himself as “sort of a night owl” who feels a boost in “my anal…

Matt outworked his peers and risen a rung too high on the career ladder—at least, too high for the good of anything but his insecure ego. Constantly fearing his bluff would be blown, he overcompensated by striving to impress upward while leading from fear. His anxiety seeped through his management team, then filtered into the ranks beneath, chipping away at everyone’s courage. He micromanaged, filtered feedback, and pushed out anyone who challenged him—the best, brightest, and boldest. When crisis hit, his “play not to lose” mentality magnified while competitors gained ground Chances are you’ve met someone like Matt. They’re crushing every deadline, exceeding ever…

There has been a lot of chatter about A24’s takeover of the Cherry Lane Theatre. What might seem a quirky side project for the independent studio known for Lady Bird, Uncut Gems, and Hereditary is in reality a sharp, shrewd move in an industry facing disruption and streaming fatigue. Live performance is one of the few cultural experiences that can’t be automated, replicated, or played on demand. By stepping into theater, A24 is hedging against an AI-saturated future while also deepening its cultural footprint. When the deal was first announced in late 2023, the scuttlebutt was rooted in practicalities. “It’s all about creative synergies,” was one refrain. “They’re divers…

When a winter storm took out the grid across Texas in 2021, Matt Popovits and his family didn’t have power for four days, and didn’t have heat in the record cold. “We spent the night huddled up lying on the floor in our living room next to our gas fireplace, just desperately trying to stay warm,” he says. “And I remember looking at my wife and saying, ‘We can never let this happen again.’” They started researching whole-house generators, but the cost, at around $15,000, was prohibitive. Last year, another storm took out the family’s power again for several days. They relied on a small generator, but it didn’t work well. Now they’ve turned to a new solution: a battery …

If you were one of the millions of children who grew up reading Goodnight Moon before bed, chances are its iconic green bedroom is permanently seared into your memory. Now, for the next four months, you have the opportunity to sleep in the Goodnight Moon room IRL. The Goodnight Moon room has been faithfully re-created—down to the red balloon, bowl of mush, and cow jumping over the moon—for a new immersive suite at the Sheraton Boston Hotel. The room can accommodate up to two adults and two children, and a booking in the suite comes with perks like four tickets to the View Boston observation deck, a $150 daily food and beverage credit, complimentary moon and star cooki…

Back in his 1996 letter to shareholders, Warren Buffett famously wrote: “If you aren’t willing to own a stock for 10 years, don’t even think about owning it for 10 minutes.” That statement only makes the recent homebuilder stock purchases and sales by Berkshire Hathaway—led by Buffett, who will step down as CEO at the end of 2025—even more eyebrow-raising. Here’s the timeline. August 2023: Berkshire Hathaway disclosed that in Q2 2023, the company made a bet on U.S. homebuilders and bought 5,969,714 shares of D.R. Horton, 152,572 shares of Le…

When Elon Musk’s foundation sponsored the $100 million XPrize for Carbon Removal—a four-year-long competition to find credible ways to eventually remove a billion tons of CO2—Musk might have expected that a shiny new gadget would win. But the winner of the $50 million grand prize is low tech: spreading rock dust on small, low-income farms in India, Zambia, and Tanzania. The winning startup, called Mati Carbon, is one of a small group of companies using “enhanced rock weathering” to capture CO2 from the air. “We’re trying to speed up something that happens naturally,” says Jake Jordan, the startup’s chief science officer. When it rains, rocks slowly break down in a pro…

How do you explain the laws of physics to a toddler? A new children’s book, titled Simple Machines Made Simple, wants to demystify mechanical engineering for kids as young as a year old. It recently beat its Kickstarter goal by 700%—raising more than seven times its target. It will be available to ship early next year. But Simple Machines Made Simple isn’t your typical picture book. Instead of drawings, the book features working models that kids can interact with, like spinning a wheel, sliding a knob up an inclined plane, and pushing a wedge into a block that splits into two. The kids may not graduate with a physics degree, but they might come away with a curiosi…

From the latest skyscraper in a Chinese megalopolis to a six‑foot‑tall yurt in Inner Mongolia, researchers at the Technical University of Munich claim they have created a map of all buildings worldwide: 2.75 billion building models set in high‑resolution 3D with a level of precision never before recorded. Made from years of satellite data analysis by machine‑learning algorithms, the model reflects a sustained effort to capture the built world in three dimensions. The result now provides a crucial basis for climate research and for tracking progress toward global sustainable development goals, according to the scientists behind it.​ Professor Xiaoxiang Zhu, who le…

For 20-year-old Mayank Yadav, riding a crowded bus in the summer months in this western Indian city can be like sitting in an oven. That makes it a treat when he steps off and into a bus stop outfitted with sprinklers that bathe overheated commuters in a cooling mist. “Everyone is suffering from the heat,” Yadav said. “I hope they do more of this across the city.” Rising heat is a problem for millions of people in India. In Ahmedabad, temperatures this year have already reached 42 degrees Celsius (107 Fahrenheit), a level usually not seen for several more weeks, prompting city officials to advise people to stay indoors and stay hydrated. And yet, coping with t…

Several times during the men’s final of the Madrid Open tennis tournament between Casper Ruud and Jack Draper last spring, TV viewers were treated to a remarkable camera perspective. They watched the match from just behind the baseline, effortlessly following the player’s movement step for step and glimpsing his perfect angle on the ball with every shot. With no discernible blur or delays, the smoothly flowing live footage had the hyper-real feel of a video game. Tennis TV “I love the footwork by the cameraman,” wrote one YouTube commenter. The company now uses the comment in its investor pitch deck. In reality, these uncanny tracking shots didn’t i…

The design of the steel-ribbed umbrella has changed little since it was introduced in the 1850s, but the mechanical engineers and origami experts who made an umbrella that works by folding say they’ve finally improved upon it. The $249 Ori umbrella has a frameless design with a laminate composite canopy, which fits into a 3.5-centimeter cylinder smart handle with an OLED display. That means there are no steel elements that can go haywire and leave you with a misshapen mess when you’re caught in a strong wind. It seems we finally have an umbrella that looks like it was invented in the 21st century. The design team included origami experts who usually work in aerosp…

Tucked in a forest of trees in Luxembourg City is a hulking piece of urban infrastructure that, if all goes to plan, will soon be taken over by birds. The structure is a two-columned concrete water tower that has been designed to function as a habitat for local and migratory birds. In contrast to most essential elements of a city’s infrastructure that usually try to avoid being infested by wild animals, this water tower had birds in mind from the very start. The water tower habitat was designed by Temperaturas Extremas Arquitectos SLP, an architecture firm based in Madrid. The project’s site is part of Natura 2000, a European ecological network of areas dedicated to…

Let’s be honest: No matter your perspective, taking in news these days tends to be a pretty tiring experience. At best, it’s a bit boring. At worst, it’s anxiety-inducing and mind-melting, often leaving you with more questions than answers. This week, a whole new kind of news app is officially breaking cover. And, I know—yadda yadda yadda, right? Another “earth-shattering” news app with more of the same as every other app before it? I had the same thought when I first came across this. Then I started to actually use it. And man alive, lemme tell ya: This is not like any other news app I’ve ever encountered. It’s fresh, it’s interesting, and it’s absolutely…

Anyone who’s visited a contemporary art museum in the past 75 years has almost certainly encountered the artwork of Alexander Calder. His delicately balanced mobiles and swooping steel sculptures are mainstays of American abstract art. But in most of those museums, from the Whitney to Pompidou Centre to the Reina Sofia, Calder’s pieces haven’t had their intended presentation. For artworks that are meant to move or be moved through, Calder’s kinetic works and supersized sculptures are often given the default museum treatment of being static, separate from visitors, or both. A new art space in Calder’s birth city of Philadelphia aims to correct that. Calder Gardens…

On my last day at my old job, I couldn’t go in. I’d been burning through sick days for months (more than I could explain to my manager) because I didn’t yet have words for what was happening to me. I was 25, running product at a tech company, trying to build a career while quietly unraveling. I’d been to the ER twice that year, seen a string of specialists, and been told by more than one doctor that my symptoms were probably psychological. I was terrified. Eventually, I was diagnosed with autoimmune disease, a condition where the immune system attacks the body’s own tissue. An estimated 50 million Americans live with an autoimmune disease, and women make up 80% of…

Using AI chatbots opens people up to numerous risks. The most obvious is that, given their propensity to hallucinate, an AI chatbot’s answers may be factually incorrect while sounding completely authoritative. But beyond this informational risk lies another worrisome one: the risk to your privacy. When you prompt and chat with an AI chatbot, the company behind it uses your queries and conversation to further train its models. Many companies, including ChatGPT maker OpenAI, say they anonymize this user data so it can’t be traced back to individuals. However, given that no major AI company has let independent auditors verify their privacy claims, you just have to take A…

Large language models feel intelligent because they speak fluently, confidently, and at scale. But fluency is not understanding, and confidence is not perception. To grasp the real limitation of today’s AI systems, it helps to revisit an idea that is more than two thousand years old. In The Republic, Plato describes the allegory of the cave: prisoners chained inside a cave can only see shadows projected on a wall. Having never seen the real objects casting those shadows, they mistake appearances for reality, and they are deprived from experiencing the real world. Large language models live in a very similar cave. LLMs don’t perceive the world: they read a…

As the economist Milton Friedman once said, “Only a crisis—actual or perceived—produces real change.” Humanity has of course been faced with countless crises, leading to profound and often unexpected change. These crises define and differentiate generations and leave lasting impacts for years to come. In 2020, a crisis that would change everything hit the world seemingly overnight. Everyone remembers where they were the day the world shut down. Offices stood empty. Cars, previously stuck in traffic on daily commutes, sat parked in driveways. Trains and buses ran empty, if at all. The bustle of Times Square turned silent and Broadway went dark. As smog cleared from cit…

Who shaped your career? Think about the people who guided, challenged, and helped you grow into the professional you are today. Do you think that artificial intelligence could have replaced their support? AI is revolutionizing mentorship by offering tailored learning, progress tracking, and administrative support. But AI has its limitations. AI cannot replace human intuition, empathy, and the ability to challenge mentees in a nuanced way. In today’s workplace, mentorship has never been more critical and complex. A new generation of employees is looking for new ways to learn and develop, and mentoring is at the top of their list. And they are not afraid to turn to …
