Standard treadmills only reach a maximum incline of around 9 degrees. But this one, developed by a team of physiologists at the University of Colorado Boulder, goes all the way to 45 degrees. The unique contraption is providing some insights into the best strategies for extreme uphill running.
This high-speed video of humans blinking allowed scientists to study the mechanics of the eye blink. It will also let them study how disconcertingly weird and creepy blinking actually is.
If you’ve watched any modern action movies, you’ve probably got a pretty good mental picture of what happens when a person hemorrhages blood. But this, my friends, is the first scientific visualization of the splatterfest. Squeamish viewers, look away.
Posture is not a rigid concept. It represents something more fluid with considerable range for change. Despite this, it is often oversimplified, rightly or wrongly, as being “good” or “bad”.
Sleeping with only half your brain sounds like a great way to become a zombie in no time, but for certain marine mammals and birds, it’s a way of life. A new study suggests that crocodiles, too, may be “unihemispheric” sleepers, a finding which makes humans and other full-brain snoozers look more and more like…
The human hand is a marvelous evolutionary invention: it can tie knots, tap out blog posts, wield tools and wire circuit boards. But how did we get these hands, with their long, dextrous fingers and conveniently opposable thumbs? It’s likely that tool-grasping played a role, but according to one evolutionary…
The 2015 Nobel Prize for Physiology or Medicine just went to three scientists who found parasite-killing chemicals that are now important tools for fighting human diseases. But the chemicals in question weren’t created in a lab: one is produced naturally by a bacterium, the other by a plant used in a traditional…
Space isn’t a very human-friendly environment to put things mildly. That’s why, as NASA has grown fond of saying, we’re sciencin’ the shit out of our astronauts so that we can learn how to keep them alive.
You may consider your eyes a priceless commodity, but for Mexican cavefish, they were a burdensome expense. In a first-of-a-kind study, scientists have figured out exactly how much energy an animal saves by abandoning vision — in this case, anywhere from 5 to 15%.
In news that definitely isn’t going to help me achieve my half marathon goal, a team of Canadian researchers is claiming that human beings are biologically wired to be lazy. Awesome.
Humans aren’t very good at dealing with heat — we either sweat miserably or rack up crazy AC bills. But some life forms have to live with scorching temperatures and extreme drought all the time. Here are some of the most bizarre strategies they’ve evolved for staying cool and hydrated.
Ever since Morpheus explained how the machines use humans as batteries in The Matrix, we’ve been fascinated by the idea. But can the human body actually generate enough current to do anything useful? We decided to find out, by asking experts how long it would take a human brain to charge an iPhone.
In 2013, researchers identified a woman who, 5 or 6 times a day, would experience spontaneous orgasms originating in her left foot. They called her condition, straightforwardly enough, Foot Orgasm Syndrome (FOS). Now, they’re searching for others like her.
When I was in graduate school, I wondered what changes made erectile tissue in the penis shift from its soft and flexible state to its stiff and inextensible state. Then, with the help of some armadillos, I did the research and figured it out. Tell me what you wonder about, and I’ll see whether I can figure it out for…
Neuroscientist and kinesiologist E. Paul Zehr has studied how a person might actually become Batman, looking at the physiology, training, and will that a person would need. And he told us how, even if you’ll never be ready for the Justice League, you can still become more like the Dark Knight.
Many popular exercises are performed incorrectly, often by people who probably shouldn’t be attempting them in the first place. This can result in injuries and futility at the gym. We talked to the experts to find out which exercises are the most problematic, and how to do them correctly.
The voice in your head is a lie. What you hear when you open your mouth is distinctly less velvety than what everyone around hears—and it's your skull that's to blame. More specifically, it's the way your skull vibrates.
Holding your breath may not be the flashiest feat of athleticism, but performing it at its highest level is still incredibly impressive, especially since it's something we've all done, and can all relate to. The limits to which some can push breath control, in fact, are more impressive than most people probably know.
Everyone knows they should warm up prior to exercise, but very few people actually bother. Turns out, that could be a real mistake: a new study suggests that warming up actually increases the maximum power a muscle can provide during exercise, as opposed to just shortening the time required to reach maximum output.
Oscar Pistorius has two carbon fiber blades for legs. Despite that, he can run 400 meters in 45.07 seconds. And South Africa, his home country, is sending him to the World Championships to compete against a field of normal-legged runners.
