There are lots of unsolved mysteries in the world of math, and many of them start off with a deceptively simple premise, like: What's the biggest couch you can slide around a 90-degree corner? Hosted by: Michael Aranda

If you've received a vaccine that's 95% effective, that does not mean you have a 5% chance of getting sick. That’s just not how the numbers are calculated. So let’s take a closer look at how it does work, why we can’t compare these...

Have a problem with many competing variables? Why not solve it with a computer algorithm based on cooling metal?

We generally think of pregnancy as a continuous process, but scientists have recently discovered mechanisms that allow for certain mammals to put the development of a fetus on pause.

You've likely been seeing the rise of AI technology everywhere—and some people are pretty concerned about what it could mean for the future. But did you know it might hold the key to understanding, and even changing, parts of our...

The UN's Intergovernmental Panel on Climate Change released the final part of its sixth assessment report. In it, they steer away from the gloom and doom and remind us of a future that's still remarkably possible.

Researchers have published a new method of guiding lightning strikes using a laser. And another team of researchers developed a new test that uses DNA as bait for respiratory viruses like COVID-19.

Hank makes it all better by explaining the biochemistry of pain -- how it works, why we have it, and how painkillers, whether they're over the counter or heavy-duty prescription bad boys, make the pain go away.

1,700 years ago, Chinese alchemist Ge Hong was renowned for his soup that could cure diarrhea-stricken patients. It had a surprising secret ingredient: feces. While it might seem unwise to consume feces, exciting new research suggests...

A quick way to compute eigenvalues of a 2x2 matrix

Paul Andersen (with the help of PatricJMT) explains why mathematics may be biology's next microscope.

Classical computers struggle to crack modern encryption. But quantum computers using Shor's Algorithm make short work of RSA cryptography. Find out how.

In this video Paul Andersen shows conceptual thinking in a mini-lesson on molecular-level structures.

In this video Paul Andersen explains the importance of models and visual representations in an AP Biology class. Science practices are overarching skills and knowledge required to be successful in an AP Biology classroom. Models for...

Just like animals, plants evolve and change over time. And you might think we'd be looking for things like fossils to figure out how they've changed, but some scientists are using a far less traditional resource: art.

If you are a teacher who is trying to make new lesson plans, or a student trying to learn more, we have some psychology hacks for you!

Have a problem with many competing variables? Why not solve it with a computer algorithm based on cooling metal?

Scientists have found some effective alternative treatments for patients with treatment-resistant depression, but they are not exactly sure why these treatments work.

TED collaborates with animator Andrew Park to illustrate Denis Dutton's provocative theory on beauty -- that art, music and other beautiful things, far from being simply "in the eye of the beholder," are a core part of human nature with...

Quantum Field Theory is generally accepted as an accurate description of the subatomic universe. However until recently this theory had one giant hole in it. The particles it describes had no mass!

Craft curator Nora Atkinson takes us on a trip to Nevada's Black Rock Desert to see the beautifully designed and participatory art of Burning Man, revealing how she discovered there what's often missing from museums: curiosity and...

Paul Andersen explains how investigations are used by scientists to answer questions and by engineers to test designs. He delineates be investigative and observational science. He demonstrates the formation of a good question the...

Even though proteins are fundamental to life, it’s hard to predict what they look like. But two independent groups announced that they’d cracked it, and it’s all thanks to some seriously clever artificial intelligence.

As we get into our unit on stratification, we inevitably return to our old friends, the three sociological paradigms. How to structural functionalism, social conflict theory, and symbolic interactionism each think about stratification?...
