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 ...

Researchers at the University of Illinois, Urbana-Champaign, developed an approach using blue light to activate the Wnt signaling pathway in frog embryos. The pathway plays a wide variety of roles in ...

Improved understanding of a neural pathway connecting light-sensitive cells in the retina with the cortical brain regions involved in mood and cognition has implications for the development of ...

RIKEN researchers have found out how light energy harvested by pigments besides chlorophyll is transferred to the molecular site where photosynthesis occurs in cyanobacteria. The work is published in ...

It’s well known that plants have a fine-tuned ability to sense changes in the season by how much daylight they’re exposed to, yet scientists observed more than a century ago that plants sometimes grow ...
