Kids are able to heal from injuries so much faster than adults thanks in part to one particular protein. As Anthony shows us, scientists are showing remarkable progress in harnessing that protein into a powerful drug enabling the body to regrow lost tissue.

The Titan Arm Exoskeleton, a mechanical strength enhancement system designed for physical therapy patients, fatigued laborers and assisted lifting, is the 2013 Dyson Award winner.
Sure some of us use our eyes to stare meaningfully into the distance, or to watch our fellow humans make word salad on the Internet. But how much do you really know about this exquisite sensory system?
Ever wondered what happens to your body if you don’t get enough water? Our bodies are mostly water by weight, so in today’s episode of SciShow Hank explains what happens to your body as it starts to shut down when you go without that tasty H2O.
Contagious yawning can be annoying, but it might also be a sign of good social skills. It’s a type of emotional contagion, a phenomenon in which we tend to share the feelings of people around us. Scientific American MIND editor Sandra Upson explains.
To some people, stress describes the frantic pace of everyday life. To others, stress is what you feel during times of conflict, loss or illness. People also react differently to stress. Some take it in stride and seem to thrive on it, while others buckle under relatively mild pressure.
Meditation can sharpen attention, strengthen memory and improve other mental abilities. Scientific American editor Ferris Jabr examines the changes in brain structure behind some of these benefits.
For 10,000 years, humanity suffered from the scourge of smallpox. The virus killed almost a third of its victims within two weeks and left survivors horribly scarred. But Simona Zompi commends the brave souls — a Buddhist nun, a boy, a cow, a dairymaid and physician Edward Jenner — who first stopped the spread of this disastrous disease, to make us smallpox-free today.
You’ve heard of junk DNA… well turns out it’s not ‘junk’ after all! As Anthony explains, that DNA is actually what gave you that pretty little face of yours.
Pain is.. a pain. Too much of it, and it can really make life hard. But imagine none of it. That can be bad too, as you’d never know if you’re hurt. That’s the reality for a select few who carry a rare genetic mutation. Trace explains how our body’s pain system works, and how these people could help those suffering from chronic pain in the future.
Unfortunately for all of us, snoring is one of the loudest noises a human can make. Noise levels of up to 92 decibels have been recorded which would make it quite impossible to sleep next to such a beast. Even more unfortunately, it’s an automatic version of the noise we use to infer derision or to imitate swine.
UCLA scientist developed biological clock able to measure age of most human tissues. Study finds, using a previously undiscovered time-keeping mechanism in the human body, women’s breast tissue ages faster than the rest of the body.
Study finds women’s breast tissue ages faster than the rest of the body By Elaine Schmidt Everyone grows older, but scientists don’t really understand why. Now a UCLA study has uncovered a biological clock embedded in our genomes that may shed light on why our bodies age and how we can slow the process. Published […]
