Similar to a light switch, RNA switches (called riboswitches) determine which genes turn "on" and "off." Although this may seem like a simple process, the inner workings of these switches have confounded biologists for decades.

(PhysOrg.com) -- The ability to control light forms the basis of many technologies, from microscopy to optical computing. Now, a team of scientists from ETH in Zurich, Switzerland, has demonstrated that a single organic molecule ...
With just a single atom, light can be switched between two fibre optic cables at the Vienna University of Technology. Such a switch enables quantum phenomena to be used for information and communication technology.
