Using light to control the brain.

This is just plain ridiculous
Dr Boyden found that it was possible to use genetically engineered viruses to introduce these light sensitive algae molecules into mammalian brain cells, or neurons as they are also called.

The virus inserts a gene from the algae into the animal cells - giving them the instruction manual they need to produce the light sensitive molecules themselves - and within days the molecules begin to appear on the surface of the neurons.

When light hits these altered brain cells, they turn on or off, depending on the gene that has been inserted.

Cassini just sent this picture back a few days ago. It was 1.6million miles away from Saturn when it took the picture, that's ~6.7x the distance from the earth to the moon and it the rings still take up more than the entire frame.



What's this about a brownie in motion?
