Inspired by Star Trek, scientists are trying to learn more about animals' brains through virtual reality, and it turns out that a component of human milk helps protect babies from bacteria!

The development of agriculture was a huge game changer for human beings and it may have even changed the way we speak.

On the genetic level, we're not all that different from chimps. But those small differences in DNA can have huge effects.

Everyone dies, but what do we do with those bodies? In this episode of SciShow, Hank explores the various options, from mummification to liquefaction, and everything in between.

Given the option, few would choose to buy products that harm the earth -- yet it's nearly impossible to know how most consumer goods are made or where they're sourced from. That's about to change, says supply chain innovator Markus Mutz....

The incredible chemical weapon-making abilities of fungi, bacteria, and plants have created a diverse array of compounds that are useful to humans.

You don't have to be a professional scientist to make a contribution to our collective knowledge. Today, we look at several projects that have benefitted from the power of citizen science!

About 10% of the world population is left-handed. But why does handedness exist and what determines which hand is dominant? Scientists have suggested several theories, but the answer may well lie with evolution.

The world of milks is much wider than your coffee shop oat variety. From rhinos to cockroaches, milk is essential for the development of many animals' offspring.
