Today Hank kicks off our look around MISSION CONTROL: your nervous system. -- Table of Contents: Sensory Input, Integration and Motor Output 1:36 Organization of Central and Peripheral Systems 2:16 Glial Cells 3:54 Role, Anatomy and...

We have a powerful way to study how brains work thanks to a relatively new technology called chemogenetics. With chemogenetics, scientists can give an injection to mice that turns specific parts of their brains on or off!

Recent discoveries about the Arc protein have shown that its function and origin may be even more complicated than scientists originally thought.

When you think "parasite," you might think of leeches or some nasty tape worm, but there are some that can live inside your very own cells. Chapters Plasmodium 0:56 Rickettsia 2:49 ROCKY MOUNTAIN SPOTTED FEVER 2:59 Legionella 4:09...

From poking their own eyes, to drinking a patient's vomit, some extremely passionate scientists have done pretty outrageous things to themselves in the name of science.

For most living things the color you see when you look at them is determined by pigments. But some of the most vivid colors we see in nature get their signature looks WITHOUT colorful molecules. How do these intense colors get their power?

Tiny versions of chromosomes show up in things like birds, reptiles, and amphibians. These mysterious lint-like flecks may be the building blocks for our entire genomes.

With their squishy bodies and color-changing abilities, octopuses and other cephalopods already look like our planet’s resident aliens. But researchers have discovered yet another thing that separates them from most other animals on Earth!

There's evidence that antioxidant-rich diets have health benefits in humans, but the antioxidant chemicals and enzymes seem to be only part of the puzzle.

Animals have all kinds of adaptations to help them get through winter, from hibernation to boots and hats. But trees have to make it through the coldest months of the year alive, too, and they've developed some pretty extreme ways to do it!

What if you were holding life-saving medicine ... but had no way to administer it? Zoom down to the nano level with engineer Kathryn A. Whitehead as she gives a breakdown of the little fatty balls (called lipid nanoparticles) perfectly...

Your urine is mostly water, but hidden in there are trace amounts of some very useful stuff!

Check out the fascinating science behind the evolution of the turtle shell, over 260 million years in the making. -- Modern turtle shells are almost as diverse as the turtles themselves. Sea turtles have flatter, lighter shells for...

Starfish can regrow lost arms, and salamanders can sprout new limbs. So why can't we? Sci Show explains the science of regeneration, and explores the limitations the humans face -- and are trying to go beyond.

For a respiratory disease, COVID-19 sure seems to affect more than just the respiratory system. Scientists think the receptor ACE2 is to blame.

Newly described wormlike fossils dating back over half a billion years might be our oldest ancestors, and researchers have mapped and visualized the physical structure of the microscopic communities growing on human tongues!

In 1881, doctor William Halsted rushed to help his sister Minnie, who was hemorrhaging after childbirth. He quickly inserted a needle into his arm, withdrew his own blood, and transferred it to her. After a few uncertain minutes, she...

In the 1950s, the people of Minamata, Japan started seeing strange behavior from the local cats, and it wasn't long before humans were showing the same symptoms.

We're on the edge of a new frontier in art and creativity -- and it's not human. Blaise Aguera y Arcas, principal scientist at Google, works with deep neural networks for machine perception and distributed learning. In this captivating...

An amazing new technology will let scientists grow new kidneys for patients using their own stem cells inside of pigs.

Hank profiles this year's Nobel laureates in science, whose achievements have helped us understand questions as small as how our cells transport materials, and as big as why matter exists at all.

Like a common cold or a cold sore, would it be possible to get a reinfection of COVID-19? Would we be able to build up long-term resistance to it?

When it comes to creating vegetarian meat substitutes, flavor is only one hurdle—smell and texture are also major factors, and scientists have been making breakthroughs on creating a convincing meatless meat experience. We also got some...

We’ve probed some 250 kilometers into Jupiter’s atmosphere, and that’s raised some new questions about the mysterious planet. And we’ve taken another important step in looking for life on Mars by using a common chemistry process for the...
