Does quantum entanglement make faster-than-light communication possible?

What is dyslexia?

Adults Science
Dyslexia affects up to 1 in 5 people, but the experience of dyslexia isn't always the same. This difficulty in processing language exists along a spectrum -- one that doesn't necessarily fit with labels like "normal" and "defective." Kelli Sandman-Hurley urges us to think again about dyslexic brain function and to celebrate the neurodiversity of the human brain.

How do pain relievers work?

Adults Science
Some people take aspirin or ibuprofen to treat everyday aches and pains, but how exactly do the different classes of pain relievers work? Learn about the basic physiology of how humans experience pain, and the mechanics of the medicines we've invented to block or circumvent that discomfort.

Is the future of the universe already determined?

How many universes are there?

Adults Science
The fact that no one knows the answer to this question is what makes it exciting. The story of physics has been one of an ever-expanding understanding of the sheer scale of reality, to the point where physicists are now postulating that there may be far more universes than just our own. Chris Anderson explores the thrilling implications of this idea.

Why Van Gogh's "Starry Night" Is Actually An Art Of Science

Adults Science
Physicist Werner Heisenberg said, "When I meet God, I am going to ask him two questions: why relativity? And why turbulence? I really believe he will have an answer for the first." As difficult as turbulence is to understand mathematically, we can use art to depict the way it looks. Natalya St. Clair illustrates how Van Gogh captured this deep mystery of movement, fluid and light in his work.

Why is the Sky Any Color?

Adults Science
It's a question that you'd think kids have been asking for thousands of years, but it might not be that old at all. The ancient Greek poet Homer never used a word for blue in The Odyssey or The Iliad, because blue is one of the last colors that cultures pick out a word for.

The Science and Beauty of Auroras

Adults Science
Space might seem like an empty place, but the area surrounding Earth is constantly being bombarded by waves of charged particles released by the Sun: The solar wind. Luckily, thanks to Earth's swirling, molten core (and the magnetic field it provides), we are protected from this planet-sterilizing onslaught like an invisible force field.

Kevin Delaney Makes a Cloud

Adults Science
Kevin Delaney from the Museum of Discovery in Little Rock performs some experiments on "The Tonight Show." Science is awesome.

Preparing for #CometLanding

Adults Science
After a ten-year journey, Rosetta and Philae had finally reached their destination, Comet 67P/Churyumov-Gerasimenko. Rosetta spent many weeks studying the comet, sending lots of information back to Earth. But where was Philae going to land? Eventually the scientists on Earth found the best place on the comet for Philae to land. Soon it was time to make the final preparations for Philae's great adventure. Both spacecraft couldn't wait any longer. The whole world would be watching as Rosetta and Philae prepared for their biggest challenge yet.

Why Are Some People Left-Handed?
