The mysterious origins of life on Earth [Science Video]
Billions of years ago, simple organic compounds assembled into more complex coalitions that could grow and reproduce. At the time, Earth had widespread volcanic activity and a hostile atmosphere that made it almost devoid of a suitable environment for living things. So where did life begin? Luka Wright searches for the cradle of life that […]
You Might Not Want to Mix These 5 Things With Birth Control [Science Video]
Many forms of birth control are hormone-based–but not everything mixes well with those hormones. This week on Reactions, learn about some common products that could make your birth control less effective or cause dangerous side effects. If you have any concerns, be sure to consult your doctor.

Let’s Code: A Computer Science Rap [Video]
From Mike: Here’s the first song in my Computer Science Rap series! I thought it would be a good idea to lay down some ground work before we get into coding. We get into questions like, what is code? Why do we write code? Who gets to write code? So let’s dive in and critically […]
Earth’s Rotation Visualized in a Timelapse of the Milky Way Galaxy
We’ve seen plenty of time-lapse videos of stars moving across the sky. Aryeh Nirenberg took a different route and stabilized the stars, therefore showing how the earth moves relative to the sky. Images were recorded at 12-second intervals over a period of three hours. [via Boing Boing]
How Some Blind People See With Echolocation [Video]
From Joe Hanson: I met Molly Burke a few months ago. She’s awesome. I absolutely love what she’s done on YouTube to bring awareness to living with disability, and turning it into ability. And her guide dog Gallop is awesome too! When Molly and I first met, we started talking about how she navigates the […]
The high-stakes race to make quantum computers work
Quantum computers could eventually outstrip the computational limits of classical computers. They rely on the behavior of atomic and subatomic particles, whose quantum states are incredibly fragile and easily destroyed— which is why this technology remains largely theoretical. How would quantum computers work, and are they really possible? Chiara Decaroli investigates. [TED Ed]
How do viruses jump from animals to humans? [Science Video]
In this video from TED Education, discover the science of how viruses can jump from one species to another and the deadly epidemics that can result from these pathogens. [TED Ed]
Einstein’s Biggest Blunder, Explained
This video is about how Albert Einstein made a mistake when applying the Field Equations of General Relativity to cosmology (in particular, to a static, constant density universe), and solved the problem by introducing the cosmological constant, rather than allowing for a dynamic universe with a scale factor – that is, the Friedmann-Lemaitre-Robertson-Walker universe, first […]
Where Are All the Women with ADHD?
For a long time, most people saw ADHD as “a boy thing.” Today, that mindset has started to shift, but even now, studies report that males get diagnosed significantly more often than females. So, what’s going on? [SciShow Psych]
