Dartmouth Medical School geneticists have discovered a new class of proteins that see light, revealing a previously unknown system for how light works.

The novel photoreceptors are part of the gears that drive biological clocks, the cellular timekeepers of the circadian rhythm, which paces life's daily ebb and flow in a 24-hour light-dark cycle. Their identification also opens a window for genetically engineered drug delivery systems that exploit the properties of these newfound molecules.
