Science Ahead

For the first time ever, a way to make visible light travel in the opposite direction is devised! As normally, light bends when it passes from one material to another like -- from air through water or glass. This phenomenon of negative refraction...

A step towards opening the door to a new generation of optical devices - like super-lenses is being taken by a team of researchers in Germany. They have developed an exotic material with a negative refractive index capable of seeing details finer then...
