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.

Introducing Crash Course Pods: The Universe
No, your eyes and ears don't deceive you - this is, in fact, a super special cross-feed treat from our friends over at Crash Course in the form of the first episode of their brand new show, "Crash Course Pods: The Universe." Hosted by novelist John Green and astrophysicist Dr. Katie Mack, "The Universe" is a podcast about the history of the entire universe, from its explosive beginnings to its mysterious, but inevitable, end. In this first episode Dr. Mack walks John through the Big Bang and the very first micro-moments of the universe, and some of the ways that that ancient event is actually still connected to us, here, today. It's great, we really like it, we're really proud of the Crash Course team, and we thought you guys would also really enjoy the show! So to make it easy, we put the entire first episode right here! The rest of John and Dr. Mack's conversation will cover 11 episodes airing every other week on the Crash Course YouTube channel at youtube.com/crashcourse or wherever you get your podcasts. Give it a listen, and we hope you enjoy!

This week, we’re joined by scientist and podcaster Amanda Wacker to talk about DNA, the building blocks of life! A blueprint for building a living thing, even!

Tiny changes in an organism’s DNA sequence can lead to big variations or absolutely nothing. It’s just a roll of the dice! So what mutations have shown up in modern humans—different bones, livers, or even eyeballs? What is “foreign DNA” and where does it even come from? And can anybody name as many X-Men as Sam?

Agriculture
A bunch of things are considered agricultural science, from planting crops and raising sheep for wool to food safety and developing fertilizers. This week, we’re skimming the surface of agriculture, with a little detour into animals that sort of farm too. What accidental evolutionary pressures turned weeds into popular crops? Why are seed vaults so important to humanity? And what made Big Mike basically go extinct, and are we worried about it happening with other crops? (Big Mike is a banana, by the way.)

Pregnancy is, biologically speaking, extremely weird! A pregnant animal’s body goes through so many hormonal and physical changes to make sure a zygote has everything it needs to grow.

This week, we’re joined by Blake de Pastino from the YouTube channel PBS Eons to talk about how plants, animals, and geologic events used to be so… huge. There are still blue whales and massive natural disasters, but the days of the Megalodon have passed. So were those big tunnels in South America really dug out by giant ground sloths?

This week, we’re talking about this famous biologist and some of the weirder science he did. What kind of books did he write after he published On the Origin of Species ?

Timekeeping
If you think about it, we’re all time travelers moving forward at one second per second… right? This week, we try really hard to define time, get sort of existential about it, and then talk about the science of timekeeping, from circadian rhythms to weird mechanical clocks. What happens to someone’s sense of time if you put them in a big bunker locked away from the outside world? How did we decide there would be 60 seconds in a minute, and did we ever try to measure time with a decimal system?

We don’t really have a precise answer to that… but this week, we’re exploring the science of big ol’ rodents! Turns out, giant rodents have shaped the environment in lots of ways, from ancient megafauna stomping through South American wetlands to beavers affecting the climate. And even though they sound kind of scary, giant rats might be able to save human lives. But the real question is: what’s up with capybara anal pouches?

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?

Dragons
Some small, magical corner of your heart wants dragons to be real, right? Well... sorry. They’re not.

Ice and Snow
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?

Advertising
From website banners to scratch-and-sniff magazine spreads, you’ve probably been the target of thousands of ads. Like, you’re even going to hear one during this podcast—we gotta eat! At this point, you might feel like you’re immune to advertising, because there’s no way a ridiculous infomercial could make you want a reusable juice box. But the psychology behind advertising has always been powerful. So this week, we’re diving into the science of when ads work, when they don’t, and when they’ve led to some pretty serious problems like the opioid epidemic.

Eggs
Eggs have tons of different sizes, textures, and protective shells, from giant ostrich eggs to squishy fish egg clusters. But, scientifically, they all boil down to the same thing: an egg is just a reproductive cell that can be fertilized by a sperm to make an embryo. This week, we’re cracking the science of eggs wide open!

Taste
Have you ever wanted to lick the Moon and find out what that grey dust tastes like? If so, you’re in luck. This week, we’re sampling the science of taste, from the Apollo 16 mission reports to how the flavor compounds in amniotic fluid may affect babies’ food preferences. Apparently, it can get garlicky in there. But can non-human animals develop a sense of taste? And is “pine mouth” a real thing, or is it just what happens when Hank eats mysterious seeds he finds in the forest?

What do the Hubble Space Telescope, the International Space Station, and the Moon have in common? They’re all satellites that orbit the Earth! This week, we’re going extraterrestrial to talk about the dreams, discoveries, and debacles that went into Mir and other weirdly cool human-made satellites. Plus, we dig into burning questions, like whether the Sun can be considered a satellite. And we’re big enough space nerds that we try to explain some celestial mechanics.

Introducing: SciShow Tangents
Introducing the lightly competitive knowledge showcase from the geniuses behind the YouTube series SciShow . Every Tuesday, join Hank Green , Ceri Riley , Stefan Chin , 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.
