Today, we’re going to visit Siberia and take a closer look at how temperatures there (and around the globe) impact the way cultures, communities, and landscapes form. Air temperature plays a much bigger role than just helping us decide...

Enantiomers have almost all the same chemical and physical properties, so it can be tough to separate them. But it’s still super important that we know how to tell them apart! In this episode of Crash Course Organic Chemistry, we’ll...

Researchers have finally determined how long a day on Venus is, give or take an episode of Brooklyn 99.

Great ideas are like electricity -- they snap into sharp focus and sprint from place to place. What's the best way to capture them? Bozoma Saint John, Chief Marketing Officer at Netflix, makes a compelling case to move away from an...

The feeling of security and the reality of security don't always match, says computer-security expert Bruce Schneier. In his talk, he explains why we spend billions addressing news story risks, like the "security theater" now playing at...

That science fiction future where robots can do what people and animals do may be closer than you think. Marc Raibert, founder of Boston Dynamics, is developing advanced robots that can gallop like a cheetah, negotiate 10 inches of snow,...

The shape of molecules is super important to life as we know it. In this episode of Crash Course Organic Chemistry we’re learning about stereochemistry and how to identify molecules as chiral or achiral. And as always, we’ll be doing a...

In 1960, Frances Kelsey was one of the Food and Drug Administration's newest recruits. Before the year was out, she would begin a fight that would save thousands of lives - though no one knew it at the time. Andrea Tone explains how...

Do you think a red minivan would be more expensive than a beige one? Now what if the car was something sportier like a corvette? Last week we introduced the ANOVA model which allows us to compare measurements of more than two groups, and...

Amy Webb was having no luck with online dating. The dates she liked didn't write her back, and her own profile attracted crickets (and worse). So, as any fan of data would do: she started making a spreadsheet. Hear the story of how she...

Hank takes you to the next frontier of innovation: the XPrize for Artificial Intelligence, talking about how true AI can be measured, and what the future might look like.

We're going back to the future! The real-life 2015 looks a little different than the movie version, though.

When we venture to new places, we need navigational tools to guide us. In organic chemistry, those are reaction mechanisms! In this episode of Crash Course Organic Chemistry, we’ll learn all about how to write reaction mechanisms. Having...

The constellation of Orion has one shoulder marked by a bright red star called Betelgeuse, but over the last year it's dimmed enough to notice with the naked eye! and mission scientists are shedding some light on how Arrokoth and other...

Today we take a look at the history and capabilities of spy satellites.

Today, artificial intelligence helps doctors diagnose patients, pilots fly commercial aircraft, and city planners predict traffic. These AIs are often self-taught, working off a simple set of instructions to create a unique array of...

Every wire, memory chip, and radio link is constantly fending off data corruption with error detecting and correcting codes. With the help of these codes, electronics can keep up the illusion of perfection… most of the time.

New Horizons is teaching us all about Pluto! And it's definitely not what we were expecting.

First thing’s first: what is media literacy? In our first episode, Jay breaks this question down and explains how we’re going to use it to explore our media saturated world.

After 14 years of going unnoticed, a vulnerability in Wi-Fi security was published last week. It's a serious problem, but it's already in the process of being fixed.

James Glattfelder studies complexity: how an interconnected system -- say, a swarm of birds -- is more than the sum of its parts. And complexity theory, it turns out, can reveal a lot about how the world economy works. Glattfelder shares...

How do the groups that you're part of affect you? How do you, in turn, affect those groups? Today we are talking about how people in society come together with a look at social groups. We’ll look at what social groups are, the different...

Researchers found water in the atmosphere of an exoplanet about 110 light-years away, and there's another rock from interstellar space flying through our solar system!
