Andres Lozano: Parkinson's, depression and the switch that might turn them off
Deep brain stimulation is becoming very precise. This technique allows surgeons to place electrodes in almost any area of the brain, and turn them up or down -- like a radio dial or thermostat -- to correct dysfunction. Andres Lozano...

Why It's So Hard To Make Better Batteries: Crash Course Engineering #32
There are batteries powering so many parts of our everyday lives, so today we’re going to talk about how they work and how we can make them better. We’ll explain how they provide power by discharging ions between a cathode and an anode,...
