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.
Follow in herpes’ path, and you’ll be walking on the the very route early humans took as they made they way around the globe. Trace shows us how this much-hated virus can reveal so much about our past.
Astronauts have said adapting to weightlessness is much easier than readapting to gravity when they returned to Earth. Muscle weakness, wobbly legs, and feeling like the room is spinning is common after long duration spaceflight, not to mention the long-term issues like bone loss, diminished eyesight, and a heart that has to recondition itself to pump blood harder to overcome gravity.
It turns out spiders have similar issues.
This video shows to convert your smartphone into a digital microscope capable of photographing cells. The setup shown here is a viable substitute for underfunded classrooms that would otherwise be unable to perform experiments requiring a microscope.
Water is a special substance for several reasons, and you may have noticed an important one right in your cold drink: ice. Solid ice floats in liquid water, which isn’t true for most substances. But why? George Zaidan and Charles Morton explain the science behind how how hydrogen bonds keep the ice in your glass (and the polar ice caps) afloat.
Like rings on a tree, human flesh can be dated in a consistent, reliable way. And as Trace tells us, this discovery could revolutionize medicine, and even enable us to extend life.
Man-made ozone hole near the South Pole shrinks according to scientists because of the warm upper air this September and October.
Scientists found gold in leaves of Eucalyptus trees in the Kalgoorlie region of Western Australia. Gold particles are from the earth via their root system and depositing it their leaves and branches.
In this episode of Crash Course Chemistry Hank blows our minds with the different kinds of Solids out there and talks about why they’re all different and have different properties. Today, you’ll learn about amorphous and crystalline solids, types of crystalline solids, types of crystalline atomic solids, properties of each type of solid, and that the properties depend on the bond types.
Science guy and leader of Thirst DC helps us understand how genes and DNA write the book of life, and how reading that book has helped us learn that everything on Earth is descended from a common ancestor.
Is time travel a fact or is it just science fiction? Thanks to time dilation and Einstein’s theory of relativity, we know that time travel can and actually does happen, albeit only in extremely tiny increments at the speeds and distances we can travel in space. If you add up the accumulated speed cosmonaut Sergei Krivalev has traveled in space – the most of any human with a total time spent in orbit of 803 days 9 hours and 39 minutes – he has actually time-traveled into his own future by 0.02 seconds.
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.
They’ve finally found a fossilized mosquito full of prehistoric blood! So a real Jurassic Park is right around the corner, right? Trace explains what exactly this discovery means, and if this means you’ll be visiting Isla Nublar any time soon.
