Short Change: Artificial Visionaries

Researchers at the Ecole Polytechnique Fédérale de Lausanne (EPFL) in Switzerland are investigating the possibility of partially restoring sight to the blind by using a device known as an optic nerve implant (ONI). The device works by bypassing the eyeball and sending electrical signals directly to the optic nerve, the pathway through which visual information reaches the brain.

Short Change: The Vampire in your Living Room

Printers, microwaves, chargers, DVD players, desktop computers and many other devices all drain energy when turned off or not in use. This drain is known as ‘vampire’ or ‘standby’ power and is responsible for a huge amount of energy loss each year. Since that energy is largely generated by burning fossil fuels, vampire power accelerates the rate of global warming as well as raising your electricity bill.
