Why the Hardest Rocks Can Be Easy to Break

From SciShow. So, rocks are hard. But the scale we use to rank them, the Mohs scale, is only really good at quantifying that for one kind of hardness, and topaz is a perfect stone to talk about to explain that. And you can check it out in our SciShow Rocks Box subscription! Hosted by:…

The First CRISPR Gene Therapy Is Here

From SciShow. CRISPR is a powerful gene editing tool, but its uses have been purely scientific until now. In 2023, US and UK drug regulators including the FDA approved Casgevy, a CRISPR/Cas9-based therapy for sickle cell disease and beta-thalassemia. The FDA also approved a similar treatment, Lyfgenia. Here’s how they work. Hosted by: Reid Reimers…

How Ancient Babylonians Predicted Eclipses

From SciShow. There’s an eclipse coming up in April of 2024!

We Don’t Know What the Sun Is Made Of

From SciShow. Unlike Earth, our Sun is a giant ball of mostly hydrogen and helium. Astronomers managed to figure that one out roughly 100 years ago. But after all this time, they still can’t come to an agreement on what "mostly" means, precisely. Hosted by: Savannah Geary ———- Support SciShow by becoming a patron on…

Why Does Everything Decay Into Lead

From SciShow. If you look at a copy of the periodic table, you might notice that basically every element after lead is labelled as radioactive. And the vast majority of those elements wind up decaying into some version of lead eventually. But why is lead so special? Hosted by: Reid Reimers ———- Support SciShow by…

Can Rock and Roll Replace Your Insulin?

Did Dinosaurs Have Belly Buttons?

From SciShow. Belly buttons are, typically, a human’s first scar. A sign that you used to feed through an umbilical cord that connected your tummy to a placenta. But it turns out you don’t have to feed from a placenta to get a similar scar. It might just be a little hard to find. Hosted…

Why Can’t We Have Unicorns?

We Finally Made Synthetic Spider Silk

From SciShow. The ability to produce synthetic spider silk would give us bulletproof vests better than Kevlar, biocompatible sutures and wound dressings, and even space elevators.

This Crystal Is ELECTRIC

From SciShow. There’s a few minerals that exhibit something called piezoelectricity and pyroelectricity, which mean that either heat or pressure can turn them electric.
