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 that is not focused by the lens onto the retina is reflected off the tapetum lucidum, where the retina gets another chance to receive the light, process it, and send impulses to the optic nerve. /news/2024-03-team-acoustic-crystal-smooth-elastic.html Optics & Photonics Sat, 23 Mar 2024 07:30:01 EDT news630322112 By infusing a virtual fruit fly with artificial intelligence, Janelia and Google DeepMind, scientists have created a computerized insect that can walk and fly just like the real thing. /news/2024-03-artificial-intelligence-virtual-fly-life.html Biotechnology Other Fri, 15 Mar 2024 13:27:55 EDT news629728067 Tests on living cell cultures are becoming increasingly important for personalized medicine, drug development and clinical research.
