Harald Haas: Wireless data from every light bulb | Video on TED.com:

What if every light bulb in the world could also transmit data? At TEDGlobal, Harald Haas demonstrates, for the first time, a device that could do exactly that. By flickering the light from a single LED, a change too quick for the human eye to detect, he can transmit far more data than a cellular tower — and do it in a way that’s more efficient, secure and widespread.

TED Talk: Ed Boyden: A light switch for neurons

Amazing talk on optogenetics and on TED:

Ed Boyden shows how, by inserting genes for light-sensitive proteins into brain cells, he can selectively activate or de-activate specific neurons with fiber-optic implants. With this unprecedented level of control, he’s managed to cure mice of analogs of PTSD and certain forms of blindness. On the horizon: neural prosthetics.
