From Reactions: The CDC is recommending that the general public wear cloth face masks to help decrease everyone’s chances of getting COVID-19. So how does the virus that causes COVID-19—SARS-CoV-2—spread? And how much could cloth face masks help stop it? We contacted some experts to find out, and to learn what materials work best if […]
What you’re about to see might look like galaxies, suns, and other scenes from space at first glance, but “As Above” features a chemical reaction captured through a lens focused on an area of just 0.3 square inch. Be sure to watch this one in full screen! As Above is a short film exploring the […]
Did you know that regular brushing and flossing might not just keep your mouth in good shape—they might also be good for your brain. [SciShow]
When you’re learning about science for the first time, it can be easier to break things down into a simpler form, and you can end up with a few misconceptions about the world. But sometimes this is the first step to understanding that things are more complex than they once seemed. [SciShow]
You might have heard that vaccine trials are currently underway in Seattle. What exactly is being tested? How much longer will these tests take? And when can we expect a vaccine against the novel coronavirus? We chat with Dr. Benjamin Neuman, one of the world’s experts on coronavirus, and Daniel Wrapp, one of the scientists […]
