SciShow Tangents

SciShow Tangents is the lightly competitive knowledge showcase from the geniuses behind the YouTube series SciShow. Every other Tuesday, join Hank Green, Ceri Riley, and Sam Schultz as they try to one-up and amaze each other with weird and funny scientific research… while not getting distracted. There will be tangents about video games, music, weird smells, surprisingly deep insights about life, and of course, poop, but it always comes back to the science.

Celebrity Science with Elah Feder Mar 05, 2019

Show notes

For our very first live show at PodCon 2, we were joined by Elah Feder, the co-host and producer of the podcast Undiscovered! Podcasting on a stage with a live audience meant we really had to bring our A-game, so we swapped stories of famous actors, politicians, and other celebrities who also dabbled in science.

Bees Feb 26, 2019

Show notes

Do you ever just wonder, “are the bees doing okay?” They’re so important to our food industry and native ecosystems, and every couple of years it seems like something horribly bad is happening to them. So this week, we’re taking a look at the fascinating lives and deaths of bees! Can they recognize human faces or understand the concept of zero? Why are blister beetles mimicking sexy bee pheromones? And what do nightclubs and honeybee hives have in common?

Artificial Intelligence Feb 19, 2019

Show notes

We’ve all heard about “The Algorithms” that affect our lives, making decisions for and about us. And artificial intelligence systems are recommending podcasts, picking out targeted ads, and playing games against humans every single day. This week, we’re going to skim the surface of AI and chat about everything from Siri to personality prediction software. How are these tools used to help the world, or are we mostly heading toward a dystopian future? What’s the Turing test and is it even a useful measure of artificial intelligence? And if a poem is written with software… is it really art? (We don’t know either.)

The Sun with Caitlin Hofmeister Feb 12, 2019

Show notes

This week, our producer Caitlin Hofmeister is joining the pod to talk about the Sun, and lending her expertise as a host of the YouTube channel SciShow Space. The Sun affects pretty much everything we do here on Earth, from our weather to our technology. So what schemes have scientists been cooking up to shield the Earth from the Sun? How have solar flares affected humans… and should we be afraid of them? And is “Guy” really a good nickname, or is this star more special than that?

Stimulants Feb 05, 2019

Show notes

Are you one of those people who doesn’t feel awake until you have caffeine coursing through your bloodstream? Well, you can choose to ingest some chemical stimulants, but they’re also something your body makes! Just think about the adrenaline rush before a public speech. This week, we’re going to dig into what science actually says about caffeine and dehydration. Why did some people try to ban coffee, and how dangerous was the pick-me-up given to some Antarctic explorers? And why the heck did researchers think gerbils could help with airport security?

Flight Jan 29, 2019

Show notes

At some point, we’ve all probably looked up at birds and wished we could fly. And some curious people took that wish and did science! From the biology of flying animals to machines that help humans take to the skies, this week, we’re exploring the science of flight. Why do we travel by plane instead of floating on airships? How long can some birds fly before landing? And what else do they get up to in midair… eating? ...sex? ...sleeping?

Mucus Jan 22, 2019

Show notes

Mucus grosses people out. Whether it’s coming out of your nose or slime oozing from an animal, it’s not really a pleasant substance. But scientifically, mucus is super cool—it can be used for protection, hunting, lubrication, or plain old stickiness. Why do some cephalopods spew out specialized mucus? Does slathering snail slime on your face actually do anything to your skin? And could eating boogers be… good?

Ice and Snow Jan 08, 2019

From sugary snow cones to WWII plans for an aircraft carrier made of ice and wood pulp, humans have had big dreams for frozen water. So this week, we’re exploring the science of snow and ice across the globe. Turns out, there are ancient refrigerators in the dry Iranian desert and abandoned military bases under the Greenland ice sheet. And even though Japanese snow monkeys seem all cozy and chill in their hot springs, what mischief do they get up to in their free time?
