Elephant seals are among the only known animals on earth to migrate twice a year, but how they do it makes the already incredible feat even more astounding.

Sounds that animals make can be really different, and it turns out that there's a reason why some species communicate with certain sounds.

Technologist and TED Fellow Gautam Shah invites us to imagine how the metaverse could redefine the relationships between humans and other species. By giving individual wild animals a personal identity (such as Fio, a young orangutan in...

In a short, funny, data-packed talk at TED U, Catherine Mohr walks through all the geeky decisions she made when building a green new house -- looking at real energy numbers, not hype. What choices matter most? Not the ones you think.

Thanks to strontium, oxygen, and rings in a tusk, scientists now have evidence that extinct mastodons may have participated in yearly migrations.

Using simple, delightful illustrations, designer Stefan Sagmeister shares his latest thinking on happiness -- both the conscious and unconscious kind. His seven rules for life and design happiness can (with some customizations) apply to...

Activist Caroline Casey tells the story of her extraordinary life, starting with a revelation (no spoilers). In a talk that challenges perceptions, Casey asks us all to move beyond the limits we may think we have.

Take a close look at some of the strangest-looking animals evolution has created.

Hank gives a quick run-down of the reasons scientists think the land mammals of today are nowhere near the size of the largest sauropods. Some of them might surprise you!

Evolution is known to be a long, slow process. But thanks to our interference, some animals have adapted at light speed in order to survive.

Paul Andersen explains how catalysts can speed up a reaction without being consumed in the reaction. Catalysts can lower the activation energy of reaction be stabilizing the transition state. They can also create new reaction pathways...

You are probably aware of the fact that elephants make trumpeting noises - but did you know that most of their communication is so low pitched that humans can’t even hear it?

In this video Paul Andersen explains how light can be treated as both a particle and a wave. Physicists use scale to determine which model to use when studying light. When the wavelength of light is equivalent to the size of the object...

Paul Andersen describes genetic drift as a mechanism for evolutionary change. A population genetics simulator is used to show the importance of large population size in neutralizing random change. The near extinction of the northern...
