Deception is necessary for placebo pills to work, or at least that’s the conventional wisdom. A surprising new study on patients with chronic back pain shows that we still experience the placebo effect, even when we know we’re being tricked.
Yeah, we know, your CrossFit gym has completely changed your life, you’ve never looked/felt better, and all other exercise programs pale in comparison. But you may want to ease off the intensive workouts now and then. All that over-exertion can actually impair your immune system, according to a new study just…
We know that astronauts’ bodies are heavily impacted by their time in space, but as more of them come back to Earth following longer and longer stays without gravity, more issues are going to arise.
Some male insects—especially beetles—boast a penis that’s several times the length of their bodies, which... wow. New research explains why these insectoid wieners need be so long, and how these bugs are still able to get it on.
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.
It takes a lot of hard work to stay in shape, which is why it’s important to exercise on a regular basis. But it’s not always possible to remain active, and sometimes a few days off can turn into a more... extended hiatus. Here’s what happens to your body when you suddenly stop exercising.
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.
The latest episode of Reactions, a series from the American Chemical Society, addresses the age-old question: Why does coffee make you poop?
The sport of freediving lost one of its premier athletes this week. Esteemed Russian freediver Natalia Molchanova was diving recreationally off the eastern coast of Spain on Sunday, when she attempted to descend, untethered, to what for her was a modest depth. She never resurfaced.
