Sperm usually swim in a 3D shimmy: a spiral wave travels down the whippy flagellum and rotates its head in a circle around its long axis. That “bulk swimming” is fine most of the time, but it isn’t a great option when a sperm cell gets close to a surface. That’s when they switch to “slither” mode.
The lamprey—a jawless, toothy suction funnel that looks like it sprung to life out of the Alien storyboards—is the sort of creature whose existence most of us would prefer not to dwell on. But lampreys are among the most efficient swimmers on Earth, and their unusual stroke could help engineers design low-cost…
Flash floods are one of the most powerful and therefor most dangerous things you can encounter outdoors. In this terrifying video, a group of hikers in Maui’s jungle is swept away.
Swimming from one end of a pool to the other in a straight line is a lot easier than trying to stay on track when swimming in a lake or open water. But a new pair of swim goggles can keep track of what direction you’re heading and help keep you swimming in a straight line using a pair of subtle LEDs.
Misfit’s button-sized Shine fitness tracker is already waterproof to a depth of over 160 feet, so swimmers don’t need to take it off while training. But since accurately measuring laps is different than measuring steps, Misfit has teamed up with Speedo to create a new version of the Shine that’s customized to track…
Orange County’s Seal Beach is a popular spot for swimmers and surfers, so its lifeguards figured they’d use a camera drone to keep a better eye on them. But what they saw instead was “10 to 12 great white sharks just feet from shore.”
Sure, you’re already doing a lot to save water—plucking the almonds from your granola each morning and shaming your grass-owning neighbors daily on Twitter. But when will you get serious about the drought and install a pool?
I've used a lot of VR headsets, but the tagline of Nautilus VR's new Kickstarter project scares the hell out of me: "Virtual Reality Underwater." Call me crazy, but that sounds dangerous. And yes, also a little awesome.
Red Bull is animating crazy surfer stories and this one from surfer Dean 'Dingo' Morrison is a doozy. It starts when he decides to buy a boat to try and catch the biggest fish he can. But him and his friends get too drunk and capsize the boat and end up swimming from island to island in search of rescue.
Shark netting strung up in coastal waters to protect swimmers from the ocean's apex predators has not worked nearly as well as we had hoped. But where these knotted nylon lines have failed, one Australian company hopes an electric field will succeed.
Meet Walter, a happy labrador that enjoys a good run before diving in the refreshing waters of Siracusa—in gorgeous Sicily. His owner obviously knows that and he strapped a Go Pro on his back so we all can share Walter's joy for life.
When you're designing a product that helps someone race through the water, it only makes sense to draw your inspiration from the ocean's resident experts. So you might be surprised to hear that Speedo closely based the design for its new Nemesis fins on humpback whales instead of sharks or dolphins. Either way, it's a…
On July 20th, I rode in a cab from my apartment to San Francisco's Aquatic Park; struggled into a wetsuit; took a ferry to Alcatraz; jumped off the boat into the Bay; and swam the mile-and-a-half back to shore. I also wore a GoPro on my head for good measure. Here's what it was like.
No one wants their young kids to fall into an unattended pool. It's (one of) a parent's (many) worst nightmare(s). iSwimband is designed to let you know immediately if the worst should happen. And probably also to keep your kids from making any friends.
As adults, we're better equipped with basic skills than a bunch of Boy Scouts, right? Prove it, could you pass the test to get a Swimming Merit Badge?
It's almost time for another steamy, sweaty summer in the city—and nothing looks like it might cool you off more than that sparkling waterway winding through the center of your downtown. But can you really swim in it? In more and more cities, the answer is a refreshing yes.
Shark skin is famously sleek and dragless, the envy of swimsuit designers. Perhaps less famous is what shark skin's oddly rough surface looks like up close: an eerie matrix of microscopic tooth-like scales. Now, scientists are 3D printing artificial shark skin in hopes of unlocking its swimming secrets.
There are some folks for whom stripping down to a Speedo in the dead of winter to hop into in a snow-lined outdoor pool sounds like a special kind of frozen-over hell. And then there is this dedicated gang of water-lovin' types who will get their laps in at the London Fields Lido no matter the weather. It's a true…
It's New Year's morning—you've got a champagne hangover and half an ill-advised Meat Lover's pizza on your nightstand. What could possibly make this day better? For some, it's jumping into an ice-fringed ocean.
Jellyfish are amazing creatures, travelling in massive blooms and pulsating mesmerically to drive themselves through the water. But how does that simple motion manage to push them through the water so quickly?
