Human Eye Proteins Detect Red Beyond Red, Michigan State University Study


12/7/2012 7:18:12 AM

We all see red every now and again, but imagine seeing red beyond red. Researchers have altered the structure of a protein normally found in the human eye so that it can absorb a type of red light that we cannot normally see. The new protein could, in theory, give us the ability to see reds that are currently beyond our visible spectrum. Colour vision in nearly all animals depends on specialised chemicals called chromophores, which sit inside proteins and absorb different wavelengths of light. Specific protein structures are thought to determine the absorption spectrum of the chromophores within.
