Your iPhone Has a White Noise Function. Here's How to Turn It On

Listening to natural sounds can lower stress, relieve perceived pain and foster a more positive disposition, according to research from the Proceedings of the National Academy of Sciences. Other studies suggest that white noise could help parents get their babies to sleep, adults learn words and improve learning in environments full of distractions. And if you're looking to buy a white noise machine for yourself or your child, your iPhone can function as one, saving you money on a new device. R

EA is reportedly hitting the brakes on the Need for Speed franchise

The Need for Speed franchise could be making its last laps — at least for the time being. Matthew Everingham, a photographer who frequently contributed to car culture website Speedhunters, said in social media posts that Electronic Arts has "shelved Need for Speed" and is "quietly parking" the series. Speedhunters, which was funded by EA and was last updated in April of this year, will also reportedly cease operations for now. EA hasn't released an official statement on the fate of the Need for

Human-Constructed Dams Have Shifted the Earth’s Poles, Scientists Say

Humans have built so many dams around the world that the Earth’s poles have wandered away from the planet’s rotational axis, new research suggests. Over the last 200 years, humans have constructed nearly 7,000 massive dams, impounding enough water to nudge the Earth’s poles by about three feet (one meter) and cause a 0.83-inch (21-millimeter) drop in global sea levels, according to a new study in Geophysical Research Letters. This drift is possible because Earth’s solid crust forms a hard shel

Why GM’s CEO is still betting on electric vehicles (and racing)

GM was the first major US automaker to make the promise to go all-electric by 2035, just four years ago. Those promises have since turned into rough estimates under the second Donald Trump presidency, with the company softening language about its electrification goals. But GM is riding high on EV sales, and as CEO Mary Barra puts it, EVs are still the future — just on a delayed (and very flexible) timeline. “We still believe in an all-electric future,” Barra told The Verge in an exclusive inter

I’ve tested all the best smart rings in 2025, and these are the only ones I would buy

While fitness trackers and smartwatches are the better-known devices in the wearable tech world, there is a third, less popular option. Smart rings are slowly becoming more attractive alternatives. I’ve tested more than a dozen of these minimalist devices, and below are the best smart rings you can buy.

Scientists Say Earth May Be Trapped Inside a Huge, Strange Void

Astronomers who examined the sound waves from the Big Bang say that the Earth — and the entire Milky Way galaxy we call home — could be trapped in a huge void billions of light years across. Their study, which was just presented at the Royal Astronomical Society's National Astronomy Meeting in the UK, could solve one of cosmology's greatest mysteries: the Hubble tension, or why the older universe appears to be expanding more slowly than younger regions. "The Hubble tension is largely a local p

I’ve been using Garmin watches for 5 years and just discovered this clever trick

Ryan Haines / Android Authority At this point, I’ve probably reviewed more than a dozen Garmin watches since taking my place as Android Authority’s resident runner. You might say it’s become a big part of my personality, but I’d argue it always was one. I’ve spent countless hours logging countless miles (alright, Strava probably has an accurate number) across everything from the Instinct to the Forerunner to the Fenix, and I thought I knew everything there was to know about Garmin’s lineup. At

The Fourth Wave: How Speedballing Is Creating a New Kind of Drug Crisis

Speedballing—the practice of combining a stimulant like cocaine or methamphetamine with an opioid such as heroin or fentanyl—has evolved from a niche subculture to a widespread public health crisis. The practice stems from the early 1900s, when World War I soldiers were often treated with a combination of cocaine and morphine. Once associated with high-profile figures like John Belushi, River Phoenix and Chris Farley, this dangerous polysubstance use has become a leading cause of overdose death

Futureproof Fiber Gives Homeowners an Edge, but Access Isn't Always Fair

We live in a fast-evolving digital age, making a high-speed internet connection as essential as running water and electricity. But a lack of affordable internet options perpetuates what is known as the broadband divide -- the gap that divides those who can or can't digitally connect in meaningful ways. A lesser-known discussion point around the broadband divide goes beyond a lack of internet access. Lack of fast internet -- fiber internet, specifically -- negatively affects home values, hurting

Which smartphone has the best battery life? I tested dozens to find the winner

If there’s one thing we all want from our next smartphone, it’s more battery life. Thankfully, battery cells are bigger than ever, while processors are increasingly frugal. This means that many, but certainly not all, flagship and mid-range handsets can take us through a day without leaving us suffering from battery anxiety. However, some phones are definitely better than others at lasting through more demanding work/life balances or taking lighter users through a second day. Not to mention, th

Google nerfs Pixel 6a batteries following fire hazard

This 19-year-old’s space company just raised millions to keep satellites connected 24/7

Apolink, a Y Combinator-backed space-tech startup founded by a 19-year-old Indian-origin entrepreneur, has raised $4.3 million in an “oversubscribed” seed round at a $45 million post-money valuation to build a real-time connectivity network for satellites in low Earth orbit (LEO).

Chat bubbles finally get the big-screen revamp they deserve in the Android Canary release

C. Scott Brown / Android Authority TL;DR Android is improving its chat bubble feature on large screen devices, pinning conversations to a new, more accessible “bubble bar” at the bottom corner. This new bubble bar remains discreetly hidden until you swipe up on it, which then expands the most recent chat bubble for you to view. While the feature is currently live for tablets and foldables in the latest Android Canary build, evidence suggests it could eventually come to phones. When you’re in
