In this video Paul Andersen shows you how to analyze and interpret data in a mini-lesson on Data. Two examples are included in the video and two additional examples are included in the linked thinking slides. <br/>

Naloxone, better known as Narcan, is today's gold standard to treat opioid overdose. But sometimes it comes up short against more potent opioids like fentanyl. So future treatments might take advantage of opioid receptor...

Some scientists believe we are in the middle of Earth’s sixth mass extinction: a big, precarious game of Jenga that involves every ecosystem on the planet. In this episode of Crash Course Biology, we’ll see how conservation biology aims...

There are huge varieties of birth control methods because there are lots of different ways to disrupt the process of sperm-egg fertilization.

Solar eclipses don't just happen here on earth - moons of other planets also pass between those planets and the sun, resulting in various types of solar eclipses on Mars, Jupiter, Saturn, Uranus, Neptune, and even non-planets like Pluto,...

Have you heard about this technique called mouth taping, and the claims it can cure everything from asthma to bad breath? We're here to cover what science and peer-reviewed research actually has to say about it.

In the US, people spend the overwhelming majority of their time inside buildings that burn fossil fuels, which are bad for both the environment and human health. (Think: breathing in air pollution from gas stoves, furnaces and water...

This video is about how physics dictates the design of modern windmills - why they are so big, have so few blades, and have such skinny blades.

One Minute Physics provides an energetic and entertaining view of old and new problems in physics -- all in one minute!

There are labs so silent that most people can't stand being inside them, but that stillness lets us run some of our most sensitive experiments.

Devastating vulnerabilities are hiding in the technology in programs, protocols, and hardware all around us. Most of the time, you can find ways to protect yourself.

The world of cryptocurrency and NFTs is riddled with controversy, but somewhere amid all of that blockchain there's some reckoning with reality that must be done.

In 1815, Mount Tambora erupted and its emissions spread across the globe, blotting out the sun for almost an entire year. This wreaked havoc on agriculture, leading to famines all across the Northern hemisphere. It was the year without...

Remember pre-school? If not, IT WAS SO MUCH EASIER! But when you were stacking blocks and figuring out which block went into which shaped hole, you were learning about properties. In this episode of Crash Course Kids, Sabrina talks about...

The third and final part of the block collision sequence.

A solution to the puzzle involving two blocks, sliding fricionlessly, where the number of collisions mysteriously computes pi

How do we find planets -- even habitable planets -- around other stars? By looking for tiny dimming as a planet passes in front of its sun, TED Fellow Lucianne Walkowicz and the Kepler mission have found some 1,200 potential new...

What do astronomers look for when they study exoplanets for signs of alien life? Hank explains how space telescopes are already yielding tantalizing clues of what other worlds might hold -- including water! -- and how the next generation...

Imagine you have a square-shaped room, and inside there is an assassin and a target. And suppose that any shot that the assassin takes can ricochet off the walls of the room, just like a ball on a billiard table. Is it possible to...

Pulsed plasma thrusters use the same stuff that’s on your frying pan to make spacecraft zoom around the universe. And they’ve been doing it since the 1960s.
