Oled

US scientists have invented a light source that could successfully substitute light bulbs we use everywhere today. The innovative light source represents the organic light-emitting diode - OLED. It emits a brilliant white light when you attach it to an electricity supply.

It is possible to print the material in wafer thin sheets that could be used to transform walls, ceilings and even furniture into lights. The OLEDs do not heat up like traditional light bulbs, implying they are remarkably energy-efficient and last longer. Moreover, the light produced by the OLEDs is more like natural daylight in comparison to bulbs.

As the vehicle stopped, Iraq's insurgents rushed out of the car that exploded with the children sitting at the backseat. Three other Iraq's witnesses became victims of the brutal att...

	Yawning Saves Your Brain From Overheating
... as a brain-cooling mechanism. In the course of the day, our brain heats up as it burns as much as third of all the calories we consume. In order to function more efficiently, the brain needs to be cooled down. Thus when a person yawns he or she instinctively increases blood flow bringing cool air. During the experiment, students were watching video tapes showing people yawning. Half of the volunteers were asked to bre...
