The Fastest Animal (Relative to its Size) Is Really, Really Fast

The world's fastest land animal (again: relative to its size) is Paratarsotomus macropalpis, a sesame-seed-sized mite native to southern California. Scientists recently clocked P. micropalpis traveling 322 body lengths per second – which, to scale, would be like a person running 1,300 miles per hour. » 5/01/14 9:40am 5/01/14 9:40am

How Do Red And Giant Pandas Coexist? The Secret Is In Their Skulls.

Red pandas and giant pandas have more in common than simply being equally adorable and included on the IUCN Red List. They both eat bamboo and live in the same habitats. How do they coexist without competing over the same resources? The secret might be hidden in their skulls. » 4/10/14 8:47pm 4/10/14 8:47pm

We finally have an accurate measurement of a cheetah's top speed

For years, the top speed of the world's fastest land animal has been listed as 64 miles per hour – but that record is based on a single measurement, taken all the way back in the 1960s. So researchers flew to Botswana, where they outfitted wild cheetahs with motion- and acceleration-tracking collars. After measuring… » 6/12/13 11:22am 6/12/13 11:22am

Allosaurus Ate Like a Terrifying Two-Ton Falcon

Tyrannosaurus rex was a thrasher, prone to vigorously shaking its powerful, prey-packed jaws from side-to-side like a crocodile. But new simulations reveal Allosaurus was equipped to dismember its prey with a little more decorum, stripping flesh from bone not with the head-swinging motion of a croc, but the meticulous… » 5/21/13 12:07pm 5/21/13 12:07pm

Watch this now. We bet you've never seen a more stunning video of a…

This is the first ever high-definition, super-slow-motion video footage of sprinting cheetahs, which — I think we can all agree — are basically the reason high-frame-rate video cameras were invented. So stop it. Stop what you're doing and watch this. Because this is more important. » 11/27/12 1:28pm 11/27/12 1:28pm

Science settles some decades-old debates about the best way to swim

As we go into the final two days of Olympic swimming — the men's open water 10k is today –- scientists are already telling swimmers how to improve their stroke for the next Olympic Games. Two different studies are reconsidering the biomechanics of swimmers' pulls, a hotly debated topic among coaches and athletes. » 8/10/12 4:02pm 8/10/12 4:02pm

High-speed video reveals the surprising beauty of moth flight

If asked to describe a moth's flight, I doubt many of us would use an adjective like "graceful." Neurotic? Yes. Flap-happy? Absolutely. But years of watching moths careen headlong into patio lights and bug lamps have left most of us with a decidedly unremarkable impression of these bugs' flying abilities. » 2/01/12 9:20am 2/01/12 9:20am

Tyrannosaurus rex was much, much bigger than we thought

An international team of researchers has used three-dimensional laser scans to determine that Tyrannosaurus rex were likely 30% more massive that we once thought — and a whole lot hungrier. Be honest, now...how many of you woke up this morning thinking you'd hear the words "three-dimensional laser" and "Tyrannosaurus… » 10/13/11 3:15pm 10/13/11 3:15pm

Toad Tongues Are a Key Ingredient in Robot Muscles

No longer will the word "robotic" refer to stiff, slow movements. We'll soon have 'bots that can pull a Miyagi and snatch a housefly out of the air with chopsticks, or, better yet, Robot Mixed Martial Arts Cage Matches! Robots are developing super-flexible physiologies thanks to current research into biomechanics,… » 6/03/08 8:00am 6/03/08 8:00am
