Dig into what happens to your brain during adolescence that changes how you value, understand, and connect to friends. -- If it seems like friendships formed in adolescence are particularly special, that's because they are. Childhood, adolescent, and adult friendships all manifest differently in part because the brain works in different ways at those stages of life. During adolescence, there are changes in the way you value, understand, and connect to friends. Shannon Odell explores the neuroscience of friendship.

Why a sausage can do what your gloves cannot - Charles Wallace and Sajan Saini

Dig into the science of touchscreens, and find out the difference between the two most common types: capacitive and resistive. -- In 2010, South Korea experienced a particularly cold winter. People couldn’t activate their smartphones while wearing gloves, so they began wielding snack sausages— causing one company to see a 40% rise in sausage sales. So, what could sausages do that gloves couldn’t? In other words, how do touchscreens actually work? Charles Wallace and Sajan Saini dig into the science of touchscreens.

Hagfish: The world's slimiest creatures - Noah R. Bressman and Douglas Fudge

Discover the extraordinary capabilities of hagfish, the slime-producing fish that has survived on Earth for over 300 million years. -- In 2017, a truck screeched to a halt. One of its containers slid off, hit a car, and spilled its contents— thousands of kilograms of hagfish. The result of this accident was an absolute mess: the highway was coated in a thick slime that took the fire department 7 hours to clear. How did these creatures create this stupendous supply of slime? Noah R. Bressman and Douglas Fudge investigate. Lesson by Noah R. Bressman and Douglas Fudge, directed by Denys Spolitak.
