In dim light a cat sees much better than you do, as do dogs and nocturnal animals. That's because the structure of a cat's eye has a tapetum lucidum, a mirror-like layer immediately behind the retina. Light entering the eye ...
For the first time, a team of researchers from the Fraunhofer Institute for Applied Optics and Precision Engineering IOF and the University of New Mexico have succeeded in cooling silica glass by 67 Kelvin through optical ...
