Improving batteries is a tough problem, but it’s also an important one because in many ways the future of our planet also depends on the future of batteries. Luckily, scientists are on the case, figuring out ways to give this essential...

The chemistry behind film photography is pretty fascinating. How do film cameras help us turn light into a physical image?

You might know that if you chomp on a Wint-O-Green Lifesaver in a dark room, you can see little blue flashes of light in your mouth. What you might not know is that this is an example of triboluminescence: a fascinating, somewhat...

SciShow explains the genetics -- and physics -- behind why blue eyes are blue, and what the future may be for the trait. Spoiler alert: Blue eyes aren’t really blue! SciShow explains!

You've heard of the Great White and the Hammerhead—but what about the lesser known but equally fierce sharks? Join Hank Green for a biting look at 7 weird sharks you're sure to love (and fear!)

Scientists and engineers are taking folding into the future!

From poking their own eyes, to drinking a patient's vomit, some extremely passionate scientists have done pretty outrageous things to themselves in the name of science.

Today's data storage solutions have an expiration date. What's on the horizon to replace them?

From the ability to see “invisible” types of light to the power to taste all over their body, meet five incredible animals whose super senses far surpass our own! Hosted by: Michael Aranda

In the 1800s, Wilhelm Kühne created an image of a window from the eyes of a rabbit. Was this technology applicable to humans? Hosted by: Michael Aranda

Hank talks about how warp drives could potentially work.

Many animals use the same five senses as we do, but these creatures take that beyond the next level.

Hanging out in the trees of Central and South America are some frogs with pretty unusual coloration. Which is to say, parts of them have no color at all. Their bellies are completely see-through!

Light pollution -- it's not just the bane of light sleepers and frustrated astronomers. It also is tinkering with the biological cycles of all kinds of living things, including us! SciShow takes you behind the glare to understand the...

Taking photos used to require technical knowledge and time in a lab, but now we have electronic devices in our pockets that do all of the work for us. How do these miracle devices do it? Hosted by: Olivia Gordon

Trees are essential to our survival—from making oxygen so we can breathe, to cooling urban environments, to literally holding the ground together to prevent erosion, trees do so much for us!

Michael Aranda substitutes for Hank again in this week's News to tell you about the winners of the 2012 Visualization Challenge, an annual competition run by the journal Science that selects the most elegant and educational graphics,...
