Chlamydomonas reinhardtii, a single-celled green alga, can’t see much at all with its eye
composed solely of photosensitive rhodopsin molecules. Yet there is more to algal
rhodopsin than one would expect. In recent years, it has triggered a revolution in
neurobiology. Ernst Bamberg from the Max Planck Institute of Biophysics in Frankfurt
helped make it famous. He is now researching these molecules and developing new
variants for basic research and medical applications.
