This week on the show Dr. Lindsey Doe, host of Sexplanations, walks us through a history of cases that have altered our understanding of gender identity. Then Jessi from Animal Wonders joins the show with Kiki, a domestic cat.

Meditation methods and the scientific method are teaming up to explore some of the deepest questions about our existence and human nature.

3D printing has grown in sophistication since the late 1970s; TED Fellow Skylar Tibbits is shaping the next development, which he calls 4D printing, where the fourth dimension is time. This emerging technology will allow us to print...

2012 may be the year of 3D printing, when this three-decade-old technology finally becomes accessible and even commonplace. Lisa Harouni gives a useful introduction to this fascinating way of making things -- including intricate objects...

Most fish are pretty sluggish in the cold. But the Pacific bluefin tuna is one of the fastest apex predators in the frigid Pacific ocean. Their physiology has adapted to help them retain more of the heat their bodies produce, except when...

There's a myth out there that music will make your baby smarter. But it turns out that Mozart will not turn your baby into Einstein.

From taking your files ransom to foiling uranium enrichment, here are five more computer viruses that you really want to avoid.

Winter means a lot of changes, and while you might think it's cold outside, some animals can't wait for it to get colder so that they have an easier time finding their next meal!

For most people, insomnia won't kill you. But in one very rare, very specific case, not only is it deadly, it's lurking in your genes.

As archaeologists pored over ancient tombs in western China, they discovered some surprisingly well-preserved and familiar relics. Though hardened over 1,000 years, there sat little crescent-shaped dumplings. So who invented these plump...

In this video Paul Andersen shows conceptual thinking in a mini-lesson on systems as parts working together. TERMS System - a set of components (e.g. things) working together Part - a piece of an object or organism This progression is...

What would it take to reimagine the limits of architecture? Débora Mesa Molina offers some answers in this breathtaking, visual tour of her work, showing how structures can be made with overlooked materials and unconventional methods --...

A new detector can use neutrinos to help us take a peek inside Earth, and a study of jellyfish galaxies can help us understand more about an unsolved problem in astronomy.

The True Science of Parallel Universes

As technology becomes more complex, it's easier for things to go wrong.

Let's look further into what we don't yet know about the Big Bang, and how the theory could progress in the future. Since there is a discrepancy between general relativity and quantum mechanics, we continue to search for a grand unifying...

On a daily basis, you spend between a third and half of your waking hours daydreaming. That may sound like a huge waste of time, but scientists think it must have some purpose, or humans wouldn't have evolved to do so much of it. So,...

MIT researcher Skylar Tibbits works on self-assembly -- the idea that instead of building something (a chair, a skyscraper), we can create materials that build themselves, much the way a strand of DNA zips itself together. It's a big...

Most stars orbit the center of the galaxy. Some stars don't. Learn what scientists think is going on, with Reid Reimers!
