The deepest hole we've ever been able to dig is just 0.2 percent of the way to the center of the Earth. What would we encounter if we could drill all the way?



Correction: We mislabeled these! These are ammonite fossils, not...

What if we could "grow" clothes from microbes, furniture from living organisms and buildings with exteriors like tree bark? TED Fellow Suzanne Lee shares exciting developments from the field of biofabrication and shows how it could help...

Hydrothermal vents are some of the most extreme environments on the planet. But in 2000, scientists discovered a vent unlike any other, one that spews white smoke and is 10 times older. And some think it may help us understand how all...

How does a robin know to fly south? The answer might be weirder than you think: Quantum physics may be involved. Jim Al-Khalili rounds up the extremely new, extremely strange world of quantum biology, where something Einstein once called...

This video is about how life arose and what its main function or purpose in the universe seems to be. Thanks to Sean Carroll for collaborating on it!

In this video Paul Andersen describes several types of evidence for common ancestry. This evidence is contained in the fossils, embryos and molecules of living organisms. Even though life on our planet is incredibly diverse there are...

Already watched the Amoeba Sisters first video on enzymes and ready to explore a little more? In this video, the Amoeba Sisters cover a few examples of enzymes in the human body before emphasizing that enzymes are found in all the...

We chose not to give a numerical value for how many characteristics of life there are, because we do not want to imply that what we are listing must be a specific order, or that it cannot be expanded upon or include exceptions....

Carolyn Porco shares exciting new findings from the Cassini spacecraft's recent sweep of one of Saturn's moons, Enceladus. Samples gathered from the moon's icy geysers hint that an ocean under its surface could harbor life.

Backed by stunning illustrations, David Christian narrates a complete history of the universe, from the Big Bang to the Internet, in a riveting 18 minutes. This is "Big History": an enlightening, wide-angle look at complexity, life and...

Despite the incredible variations of life we see today, at the fundamental level, all living things contain three elements: Nucleic acids, Proteins, and lipids. These three things had to have been present in order for...

How low in complexity can you go and still have free will. Does a bacteria have free will? Do single cells have it? What do we know about agency in living systems? I collaborated with physicist and author Philip...

SUMMARY

The second law of thermodynamics states that overall entropy of any isolated system can never decrease. Entropy is a measure of the disorder in a system (roughly). However, living things don’t seem to...

We just finished looking at some catalytic hydrogenation reactions, so let's look at another extremely important application of hydrogen gas. Ammonia is a critically important compound for many reasons, particularly fertilizer production...

Viruses and bacteria have their own set of characteristics that distinguish them. But what are those differences? Well, in this video, we will cover the main differences between those 2 groups of microbes.

This video explores the advancements in scientific and medical research that are pushing the boundaries of life itself. It delves into the concept of aging, the theories behind it, and the factors that contribute to it. The video also...

Most people believe that Homo sapiens are the only humans to have ever walked the face of the Earth. However, this isn’t true. We just happen to be the only human species left. The ever-so-familiar portrait of an ape evolving into a Homo...
