Some Barefoot Runners Tip Orthodoxy Back on Heels

barefoot running rear foot strike

Barefoot, five-finger, super-minimal, zero-drop. Whatever joggers embrace as the approach-du-jour for improving form, most of these trends stem from one physiological principal: people who grow up running sans footwear—the way our ancestors did for hundreds of thousands of years—run by landing on their fore- or mid-foot.

Did Human Ancestors “Walk” Up Trees? [Video]

A new study suggests that we might be thinking about tree climbing in our recent ancestors all wrong. The traditional idea that our ancestors descended from the trees and gradually—and exclusively—began walking upright might be a gross over simplification. Fossil evidence from early hominins suggests that adaptations for tree climbing, such as long arms and [...]

How would you walk if you had five arms and no brains? If you’re a brittle star, the answer turns out to be quite well (for an echinoderm)—although it’s a little complicated.

I could see from the signs – simple design, plastic construction, strapped to utility poles – that they weren’t a civic undertaking. Amazing: guerilla direction signs. A culture in [...]

ASPEN. Life can change in an instant. We all know this, but we forget, or try to forget, this fact—until something happens that makes it hard to ignore. An attractive blonde in a bright red blouse sits in a wheelchair before the assembled scientists, doctors, writers and members of the community. We are in a [...]

Scientists Discover the Very First Hipster

14-001FEATURE

You’ve seen the cartoon before: a fish hoisting itself up on land with its front fins, being greeted with some snarky sign like, “Evolve at your own risk,” or something similar. This fish has become a meme, so much so that when the discovery of Tiktaalik roseae, a 375-million year old fossil that displays a [...]
