Hooked On Light - Could Reveal The Biochemistry Of Addiction

mouse responding to light 

A newly created set of light-sensitive proteins grants scientists unprecedented control over the brain’s biochemistry, potentially shedding light on addiction and other complex neural processes. To demonstrate the potential of this novel molecular toolbox, researchers from Stanford University engineered mice to carry light-sensitive proteins in the brain’s reward center, which responds to drugs of abuse. Using pulses of light delivered directly to the brain, researchers were able to induce a druglike state, ultimately conditioning the mice to behave like drug-addicted animals.

Faster Wireless to Compete with Speed of Fiber

Faster Wireless to Compete with Speed of Fiber

 Researchers at Battelle used off-the-shelf optical telecommunication
components to create a faster millimeter-wave device.

There’s no shortage of demand for faster wireless, but today’s fastest technologies–Wi-Fi, 3G cellular networks, and even the upcoming WiMax–max out at tens or hundreds of megabits per second. So far, no commercial wireless system can beat the raw speed of optical fiber, which can carry tens of gigabits per second.
