Researchers map vital atomic-scale protein on COVID-19 – submitted by Kris Lee
Scientists have announced a critical breakthrough in their research for a vaccine to comabt COVID-19 (coronavirus) by creating the first three-dimensional (3D) atomic-scale map of the section of the virus that attaches to and infects human cells. Click here for the...
Water Is WAY Weirder Than We Thought
https://youtu.be/hdik-ySEetI Water is one of the most abundant and important substances on Earth, so you think we'd know everything there is to know about it. But it turns out water is way weirder, and it often behaves in ways that leave scientists with more questions...
HOW DOES COVID-19 AFFECT THE BODY?

Why Do People Say We’ve Reached the End of Physics?
https://youtu.be/DGS2aWUKZ38 Our fundamental picture of the universe seems pretty nearly complete these days, to the point that some people are suggesting that we’ve arrived at some version of “the end of physics.” And sure, physics is at a turning point, but it might...
How Ancient Ice Proves Climate Change Is Real
https://youtu.be/myxVsYI4WZk Earth’s climate is changing in a big way, and it’s because there's more carbon dioxide in the atmosphere than at any point in our species’ history. But Earth’s climate has changed before. How do we know that this time we’re the cause? We...
Introduction to Balancing Chemical Equations Video
https://youtu.be/yA3TZJ2em6g How to balance chemical equations. We'll start out with examples that show the concepts behind balancing chemical equations. We will start with a word equation, and then write a chemical equations, and then visualize the atoms and...

Sea Monster Fossil Discovery – CBC – submitted by Kris Lee
An iguana-like creature with a needle-sharp snout has been confirmed from a fossilized skeleton as a species of the marine reptile thalattosaur previously unknown to science that roamed the coast of what is now Alaska some 200 million years ago. Click here for the...
Human Circuit – Conductors and Insulators – by Steve Spangler
The Energy Stick makes quite the “buzz” when you’re using it. To the untrained eye, it appears to be a plastic tube with a jumble of wires inside and two silver bands at each end. Well, those silver bands are actually electrodes. All the wires on the inside? They’re a...
