Light can trigger key signaling pathway for embryonic development, cancer

Blue light is illuminating new understanding of a key signaling pathway in embryo development, tissue maintenance and cancer genesis. Researchers have developed an approach using blue light to activate the Wnt signaling pathway in frog embryos. The pathway plays a wide variety of roles in animal and human development, and the ability to regulate it with light will allow researchers to better study its assorted functions, the team says.
