Thousands remain trapped between life and death. Three scientists are working to free them. Roger Highfield reports.
How to Mold a Brain
Posted in: Today's ChiliOur brains are inherently plastic, and can be easily shaped to change our behavior. In this video Crash Course looks at the history of psychology to explain how possible to mold our grey matter
This is wild. Chasing the elusive dream of curing paralysis, a team of scientists used stem cells and optogenetics to circumvent the central motor system of lab mice whose nerves had been cut. This enabled them to blast individual motor neurons with a laser, triggering movement in the legs of the mice.
If this looks like an incredibly complex wiring diagram to you, it’s because it kinda is: you’re looking at the Allen Mouse Brain Connectivity Atlas, the first detailed map of any mammal’s neural network.
Fantasizing about an old flame? Lusting over a celebrity instead of your current squeeze? Watch out: scientists can reconstruct the faces you’re thinking about from a brain scan alone.
While you might sometimes find it annoying that you can’t remember faces, names and details, forgetting is an important part of the brain if we’re not to become cognitively overwhelmed. And, it turns out, the brain takes a very controlled approach to how it goes about it.
Inside the Teenage Brain
Posted in: Today's ChiliThe teenage brain can be a very strange place indeed—for the owner and anyone around it. This video peers inside the adolescent skull to explain exactly why that’s the case.
Researchers call it the Fly Mind-Altering Device (aka "FlyMAD"), and to demonstrate the system’s effectiveness, they’ve shown that firing a laser at the head of a fly can compel it to flirt, and attempt to copulate, with a ball of wax. (Come on. You know you want to watch this.)
Long live Flappy Bird, the game we loved to hate
You wake up, tired and groggy, and you can think of only one thing: coffee. But in reality, first thing in the morning isn’t the best time to hit hit the caffeine—and it’s science that says so.
