Some of humanity’s favorite antibiotics are starting to lose their mojo, in the face of smart, sneaky, and rapidly-evolving bacteria. To find new drugs to combat these superbugs, scientists are looking in some weird new places, like...

The aftermath of the collapse of the Soviet Union and its Warsaw Pact had a huge impact on the countries of Eastern Europe. As the former satellite states turned away from communism and Soviet influence, some of them shifted toward...

Serotonin is the chemical messenger we can thank for being related to feelings of happiness, and one of the ways you can produce this chemical is to turn to our old friend nature! So maybe a visit to the dog park really can make you feel...

Squeaks and Jessi use their pretend time machine to go way back in time and meet a creature even older than dinosaurs, called Dimetrodon!

This week on Crash Course mythology, Mike is talking to you about floods. You may have heard the story of Noah and the Ark from the Bible, but that is not the only deluge story humans tell. It's a common thing across culture. You could...

Today we conclude our unit on Philosophy of Religion and Hank gets a little help from Indiana Jones to explain religious pragmatism and Pascal’s Wager, fideism, and Kierkegaard’s leap to faith.

The origin of life is one of the most important mysteries in all of science. When did life begin? How did life first evolve from chemistry? Where did life get started? In some primordial soup or somewhere else? Let's journey back to the...

Natsai Audrey Chieza is a designer on a mission -- to reduce pollution in the fashion industry while creating amazing new things to wear. In her lab, she noticed that the bacteria Streptomyces coelicolor makes a striking red-purple...

As we look towards longer missions to the Moon, the shear amount of resources needed to survive becomes a much bigger question. Without space semi-trucks to haul life-giving resources to astronauts, can we utilize the Moon’s barren...

Today we start our unit on language with a discussion of meaning and how we assign and understand meaning. We’ll cover sense and reference, beetles in boxes, and language games. We’re also getting into the meaning-making game ourselves:...

For intersex people -- those born with sex characteristics outside the traditional definitions of female and male -- the stakes to appear "normal" are high. Drawing on her personal experience, Susannah Temko reveals the shame, prejudice...

Scientists are working on creating organisms with designer genomes -- and someday, we might end up with bacteria manufacturing our jet fuel.

When it comes to water on Earth, life finds a way. Even in the hottest, most acidic, and saltiest waters in the world, odds are you'll find some kind of organism adapted to live in it. There is, however, a place with water so extremely...

Ratites have spread to Africa, Australia, New Zealand, and South America. And there are fossils of Ratites in Europe, Asia, and North America too. That's a lot of ground to cover for birds that can't fly. So how did Ratites end up all...

Back in 1862, soldiers fighting in the American Civil War noticed a strange blue glow on their wounds. It took a couple of High School students to figure out what it was.

It's really difficult for life to create blue pigments, but the color can appear in a handful of compounds that create just the right conditions to reflect blue photons.

Chromosome shenanigans have resulted in some unexpected hybrid fishes. Also, this record-breaking mouse lives at a ridiculous altitude.

The healthcare industry in America is so focused on pathology, surgery and pharmacology -- on what doctors "do" to patients -- that it often overlooks the values of the human beings it's supposed to care for. Palliative care physician...

Extreme environments full of life on Earth have led researchers to expand the definition of habitability to something that includes many more planets, potentially leading us to evidence of living things in a dramatically shorter time!...

Sharing his experience of being held captive in a Taliban prison for 105 days, humanitarian Safi Rauf talks about his life's mission to get food, medicine and other critical supplies to Afghans in need -- and urges the world to bolster...

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!

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!
