If you celebrate American Thanksgiving, odds are you're full of food and pretty sleepy right about now. While you drift off for a post-feast nap, enjoy this compilation of episodes covering all kinds of different sleepy, science-y topics!

Earlier this month, we talked with Daniel Skovronksy, the Chief Scientific Officer of Eli Lilly, about their colorfully-named COVID-19 treatments. We also discussed the challenges of mass-producing antibodies and how medicine might...

The pigments in our food all get destroyed on their way through our digestive system...so where do the colors of our poop and pee come from? ________________________ FYI: We try to leave jargon out of our videos, but if you want to learn...

Jimmy Lin is developing technologies to catch cancer months to years before current methods. He shares a breakthrough technique that looks for small signals of cancer's presence via a simple blood test, detecting the recurrence of some...

Is it possible for there to be a dog that is made of one very determined cell?

As many as 50 million people worldwide may live with Alzheimer's and similar forms of dementia, and while we still don't understand a lot about it, scientists may be one step closer to an effective treatment.

Since measles vaccines started making their rounds, child mortality has dropped by up to 90% percent in some countries. That’s more than you’d expect if the measles vaccine just prevented deaths from measles. Can science explain this...

The FDA recently approved two mRNA vaccines for COVID-19, but it was a challenge to make this type of vaccine work. And it took decades of research to get us to the point where scientists could make those vaccines as quickly as they did.

In the past couple years, you may have found yourself wishing that all the viruses in the world just disappear. But be careful what you wish for...

If you've heard of Toxic Shock Syndrome, you might think you can only get it from tampons, but the bacteria that cause this problem are surprisingly common and we still don't know why they sometimes turn deadly.

How does cancer know it's cancer? At Jay Bradner's lab, they found a molecule that might hold the answer, JQ1. But instead of patenting it and reaping the profits (as many other labs have done) -- they published their findings and mailed...

When faced with threats ranging from snake bites to COVID infections, some white blood cells retaliate with a peculiar tactic: spewing out their own DNA to form pathogen-trapping nets. But research suggests that sometimes this...

In 2017, a truck screeched to a halt. One of its containers slid off, hit a car, and spilled its contents— thousands of kilograms of hagfish. The result of this accident was an absolute mess: the highway was coated in a thick slime that...

Oceanographer Penny Chisholm introduces us to an amazing little being: Prochlorococcus, the most abundant photosynthetic species on the planet. A marine microbe that has existed for millions of years, Prochlorococcus wasn't discovered...

The elephant is a creature of epic proportions -- and yet, it owes its enormity to more than 1,000 trillion microscopic cells. And on the epically small end of things, there are likely millions of unicellular species, yet there are very...

Herein we explain how pets can help your immune system, beginning when you're in utero!

Do larger creatures get cancer more frequently?

Scientists are trying a little bit of everything to fight the virus that causes COVID-19, but some researchers are harnessing more than just the usual virus-fighting repertoire, from tiny sponges to viral RNA-destroying bubbles.

Over the past few weeks, the Nobel committees have been announcing the 2015 laureates. This year’s winners in the physics and chemistry categories made discoveries about the tiny neutrinos flying through all of us, and the ways our...

Optogenetics may allow us to use light like a remote control for our brains, and treat diseases like retinitis pigmentosa.

Generally, when you think of carbon monoxide, nothing good comes to mind. And that’s… pretty reasonable. But elephant seals show us how we might be able to use carbon monoxide as an effective therapy for heart attacks and strokes.

Shielded by our thick skulls and swaddled in layers of protective tissue, the human brain is extremely difficult to observe in action. Luckily, scientists can use brain organoids - pencil-eraser-sized masses of cells that function like...

What happens when you don't sleep? And why do we need to do it anyways? Hank explains the science of sleep: the cause, the benefits, and who holds the record for going without it!

The news of several promising COVID-19 vaccines over the past few weeks has been very exciting, but so far, none have received emergency authorization for general use in the US. We'll talk about what that means, and also, why these...
