New Research Debunks Myth That Brain Cells Stop Growing After Childhood

You’ve probably heard the old canard that new brain cells simply stop forming as we become adults. But research out today is the latest to show that this isn’t really true. Scientists in Sweden led the study, published Thursday in Science. They found abundant signs of neural stem cells growing in the hippocampus of adult brains. The findings reveal more about the human brain as we get older, the researchers say, and also hint at potential new ways to treat neurological disorders. “We’ve found

xAI data center gets air permit to run 15 turbines, but imaging shows 24 on site

After months of backlash over alleged pollution concerns, xAI has finally secured an air permit covering some of the methane gas turbines powering its Colossus supercomputer data center in Memphis, Tennessee. On Wednesday, the Shelby County Health Department granted xAI an air permit that allows it to power 15 gas turbines while adhering to a range of restrictions designed to minimize emissions. Expiring on January 2, 2027, the permit requires xAI to install and operate the best available contr

Nothing Says the Phone 3 Isn’t One Big Gimmick, but I’m Not So Sure

Nothing CEO Carl Pei wants you to know one thing: the startup’s smartphones aren’t just relying on a schtick. The Phone 3, which was finally unveiled this week after seemingly never-ending leaks and teasers, is being billed as the company’s “true flagship,” which means… to be honest, I don’t know what the hell it means. But it’s clear that Nothing sees it as its most premium phone yet, which is evident not just through its own messaging but also its starting price. The Phone 3 costs $800—more th

Experts Say These Are the Best Foods for Headaches

While eating a certain food or adjusting your diet won't provide a miracle cure for headaches or migraines, it may offer some relief. That is, in addition to maintaining your hydration, exercise, sleep and stress management. "The most important thing I tell patients is that migraines are highly individualized," says Dr. Nicholas Church, a board-certified member of the American Board of Family Medicine and the American Academy of Family Physicians. "What helps one person may not help another, an

Best Family Phone Plans for 2025

If you compare the specifics of T-Mobile's Essentials and Essentials Saver plans, you might think the company forgot to update one or the other -- they're Essential-ly the same. With both, you get 50GB of fast Premium 5G data (depending on the network capabilities in your area), which drops to 3G speeds of still-unlimited data after that allotment is used up. You can use your phone as a mobile hotspot with unlimited data, but only at 3G speeds and restricted to paltry 2G speeds when you're in Ca

Serenading Cells with Audible Sound Alters Gene Activity

The cells in your ears aren’t the only ones listening: recent research suggests that crucial cells throughout the body may respond to audible sound. Experiments described in Communications Biology revealed more than 100 genes whose activity changed in response to these acoustic waves, pointing to possible medical applications. Extensive earlier research has shown that ultrasound—sound at frequencies higher than humans can hear—can affect biology in numerous ways; the new study expands this conc

Despite Protests, Elon Musk Secures Air Permit for xAI

A local health department in Memphis has granted Elon Musk’s xAI data center an air permit to continue operating the gas turbines that power the company’s Grok chatbot. The permit comes amid widespread community opposition and a looming lawsuit alleging the company violated the Clean Air Act. The Shelby County Health Department released its air permit for the xAI project Wednesday, after receiving hundreds of public comments. The news was first reported by the Daily Memphian. In June, the Memp

Rocket Engines That Flew 22 Space Shuttle Missions Are Ready for NASA’s Next Moon Mission

NASA’s Space Launch System (SLS) is ready to fly with its four shuttle-era engines. The rocket, outfitted with the RS-25 engines, recently passed a critical milestone that put the integrated system to the test, using a decades-old design on a new launch vehicle.

Business Class Ain’t What It Used to Be. Don’t Tell First Class

Five years ago, Covid-19 largely brought business travel to a halt. Now companies are getting their employees back in the air, and carriers are reinventing themselves to appeal to post-pandemic fliers willing to pay more. Airlines worldwide are reconfiguring the real estate on their planes by segmenting their cabins into higher-margin business-class seating. They’re beefing up their traditional business cabins to snag higher fares while providing more luxurious premium economy seating for trave

A Group of Young Cybercriminals Poses the ‘Most Imminent Threat’ of Cyberattacks Right Now

Empty grocery store shelves and grounded planes tend to signal a crisis, whether it’s an extreme weather event, public health crisis, or geopolitical emergency. But these scenes of chaos in recent weeks in the United Kingdom, United States, and Canada were caused instead by financially motivated cyberattacks—seemingly perpetrated by a collective of joyriding teens. A notorious cybercriminal group often called Scattered Spider is known for using social engineering techniques to infiltrate target

Got a Samsung TV? I recommend changing these 6 settings for the best performance

Kerry Wan/ZDNET Say you recently picked up a shiny new TV. You unbox it like a kid at Christmas and prepare to indulge in all its visual glory. You think to yourself, "This is 2025. TV technology is sizzling, and it's going to look amazing no matter what." So you plug it in and don't take one look at the default settings. Big mistake. Also: How to clear your TV cache (and why it greatly enhances your viewing experience) I've been guilty of it. And I'm OK with that because it's widely accepted

Gene therapy restored hearing in deaf patients

“This is a huge step forward in the genetic treatment of deafness, one that can be life-changing for children and adults,” says Maoli Duan, consultant and docent at the Department of Clinical Science, Intervention and Technology, Karolinska Institutet, Sweden, and one of the study’s corresponding authors. The study comprised ten patients between the ages of 1 and 24 at five hospitals in China, all of whom had a genetic form of deafness or severe hearing impairment caused by mutations in a gene

Airport Lounges Are Sexy Again—if You Can Get In

Let’s be honest: A crowded airport lounge without a seat in sight is usually less appealing than an empty gate area. Over the past decade, an influx of travelers with club access has led to overcrowding, long waitlists, and a diminished (read: not luxurious) experience. However, a version of commercial air travel—often hidden from public view and inaccessible to even premium credit cardholders—has emerged. This more private, pre-flight experience is essential for the affluent business traveler,

Affluent Travelers Are Ditching Business Class for Business Jets

We’re cruising 35,000 feet over the French Riviera, the plane’s wing cutting through billows of white. Below us, the sea is sparkling, and I spot a cluster of yachts anchored along the coastline. A ray of light hits my glass of Champagne and turns it to liquid gold. I take another sip. So this is what it feels like to be on cloud nine. I’m flying from London to St. Tropez with the private aviation company Wheels Up, and for the first time in my life, I don’t want a flight to end. Once you’ve go

For Today's Business Traveler, It's All About Work-Life Integration

These days, business travel no longer means putting your life on hold. In my own work as a travel writer, forever shuttling between airports and hotel lobbies, I lean on small habits that make unfamiliar places feel less anonymous. Before work takes over, I’ll put on a Greek or Arabic podcast to keep the languages of my family close to me. They’re the ones I grew up hearing around the dinner table, and there’s a quiet fear they’ll slip away if I stop listening. Folding moments like these into my

Bezos-funded satellite tracking methane emissions loses power in space

MethaneSAT, the Environmental Defense Fund (EDF) methane-tracking satellite backed by the Bezos Earth Fund, is lost in space. Its ground team lost contact with the spacecraft on June 20 but tried to reestablish a connection until it learned in the morning of July 1 that MethaneSAT had lost power altogether. The team believes that the satellite is likely not recoverable. MethaneSAT collected data on methane emissions that have previously been untrackable in an effort to combat climate change. Met

Come for the Amenity Kits, Stay for the Flight

Last March, Air France hosted a private event at the upscale Ritz Paris hotel in Place Vendôme, in the luxurious heart of the city. The airline had built a full-scale mock-up of its new La Première first-class cabin and treated travel journalists like its most valued customers. The new cabin was classic and elegant, a showcase of the Air France aesthetic. Matteo Rainisio, founder of the Italian frequent-flier website The Flight Club, who was in attendance, called it akin to haute couture. Each

Business Travel Is Evolving Faster Than Ever. We’ll Help You Navigate It

It might feel like a distant memory, but in 2020 the Covid-19 pandemic radically transformed how people lived, and specifically how they worked. At the time, plenty of health experts, CEOs, and publications (including WIRED) predicted that Covid would grind business travel to a halt indefinitely. If our day-to-day tasks and meetings could happen using Zoom, Slack, and other online tools, the logic went, then why not apply that same digital-first philosophy to work trips? But near the end of tha

Airplane Wi-Fi Is Now … Good?

Expensive and erratic, in-flight Wi-Fi has been more of a punchline than a pipeline over the past decade. But 2025 has marked a sea change for the skies: the rollout of fast, and free, connectivity on most of the world’s major airlines. Satellite technology has enabled leaps in speed and bandwidth. SpaceX’s Starlink network of low Earth orbit satellites, for example, can deliver a connection capable of downloading more than 200 megabits per second—twice as fast as most basic home internet plans

Mystery recall of iPhone engineers may be Chinese interference in Apple’s plans

More than 300 Chinese iPhone engineers and technicians have been recalled from an Indian production plant, says a new report. No public acknowledgement or explanation has been offered, but suspicion is falling on the Chinese government, which has previously been accused of actively hampering Apple’s attempts to move more iPhone production out of the country … Mystery recall of iPhone engineers Bloomberg reports. Foxconn has asked hundreds of Chinese engineers and technicians to return home f

Deaf Teenager and 24-Year-Old Gain Ability to Hear After Experimental Gene Therapy

In recent years, gene therapy has emerged as a promising treatment for genetic forms of congenital deafness—hearing loss that’s present at birth—in children. A new study shows that gene therapy can bestow hearing in teenagers and adults with this condition, too. The study, published Wednesday in the journal Nature Medicine, recruited patients with deafness or severe hearing impairment caused by mutations in the OTOF gene. This gene manufactures a protein called Otoferlin, which plays a critical
