New Light Devices

How many scientists does it take to screw in a light bulb? Well, soon you will not need any. Some Glasgow University scientists have developed new technology for light sources that will be brghter and use less power than the most energy efficient light bulbs on the market now. This is good news for humans. It does not make much difference to dogs, though. We have much better night vision than humans as it is, so we have little use for light bulbs one way or the other.
