A professor from the University of Wyoming in Laramie has engineered proteins that can be activated by near-infrared light.
Molecular Biology Professor Mark Gomelsky (gum-el-ski) says the technique offers a way to control biological activities in deep tissues of small mammals.
He says such proteins will be used as research tools to better understand the biology of certain diseases.
He expects the proteins to aid in fighting cancer, heart disease and other illnesses. Gomelsky is the lead writer of a paper published this week in the Early Edition of the Proceedings of the National Academy of Sciences.
