DESCRIPTION:Some cyanobacteria have a remarkable ability to navigate towar
 ds light-sources. How can something that small see where the light is comi
 ng from? We showed a few years ago that the spherical cyanobacterium Synec
 hocystis works like amicroscopic eyeball\, with the cell body as the lens 
 and the cell periphery as the retina. I will discuss our recent progress w
 ith this problem: the physical basis for the lensing properties and the bi
 ochemical basis for light perception\, signal transduction and control of 
 the motility apparatus. There are some unexpected connections with both ph
 otosynthesis and the circadian clock.
