It's the year 2018, and we now know that flies like to ejaculate. But how does this tie into our understanding of addiction?

Big-brained scientists have found the mechanism that may have allowed their brains (and all humans') to get so big.

Hank usually likes to keep science and politics separated, but the reality is that a lot of scientific research in the United States is funded by the government. This is a problem right now because the disfunction in the world of...

What really killed Mozart?

Some researchers think mitochondria could be hiding the key to Alzheimer's disease. And we may have a new strategy to fight the threat that the global banana industry has been facing for decades.

We’re all excited about the Mars rover Perseverance this week, but scientists are also working on some other exciting things!

Oxygen is pretty great stuff, but this recently discovered organism couldn’t care less about oxygen. It breathes nitrogen and may offer a window into how the types of cells in OUR bodies may have evolved billions of years ago.

This week, CERN announced a new particle that will help further understanding of the fundamental forces, and a simulation of ancient creatures may give us a clue as to how life grew beyond the microscopic.

Turns out doing the crossword is only one way you can keep your head healthy because mushrooms can help your brain cells grow!

While children are only a small minority of those who test positive for COVID-19, we’re starting to see evidence of a rare, but serious, complication in children that resembles a condition known as Kawasaki disease. Here’s what doctors...

For the last hundred and fifty years or so, geologists have been trying to wrap their heads around the mystery: in some places, the geologic record just seems to jump by over billion years. And last week, a paper was published that may...

We’d pictured the plant-fruit relationship as one-way, but new research reports that sometimes the fruit can talk back! And while cow burps are a widely cited contributor to climate change, it turns out that wild pigs might also be...

Do you ever think of what could cause the next big extinction? How about a super massive tropical storm that sweeps over continents? Hey, it could happen! Check out this SciShow Dose to see how a hypercane would be possible.

Once upon a time, there was a lake that was so radioactive, that standing on its shore for more than an hour would almost definitely kill you. Join Olivia to learn how it got that bad in the first place, and what was done to fix it!

Olympic National Park is temporarily closed as Washington, the US, and the world work to mitigate the spread of the COVID-19 virus. We filmed this series in early January and are currently at home practicing social distancing. We hope...

Working in the White House in the 1840s may have been more hazardous than we thought.

Searching for a cure for rickets led to the discovery of vitamin D. Fortifying foods with vitamin D led to another disease, and a whole new way to view genetic disease in general.

This week, a group of researchers use nuclear fallout to figure out how old liver cells are, while another gets one step closer to predicting volcanic eruptions.

Scientists who piece together our past can do so through the rare fossil or artifact, or they can go to one convenient location: a hyrax latrine.

Oxygen is crucial for life as we know it, but before it could build up in our atmosphere, earth had to slow down.

Did you know that dogs can tell when you're stressed out? But how do they know? Turns out they can smell it! Join Hank for a new episode of SciShow and learn all about it! Hosted by: Hank Green (he/him)

The cold medicine you picked up at the store involves some cool chemistry to treat your symptoms. *Correction: This episode was written by Alison Caldwell.

Sleep is complicated. And there's still a lot we don't know about it, but zebrafish larvae are a surprisingly good place to look to learn more about what makes us sleepy.

In the future, we may see more continent-sized dust storms like the one nicknamed Godzilla, which crossed the Atlantic ocean in 2020. And since then, researchers have been looking into what caused such a colossal storm. If we can predict...
