Marine organisms use previously undiscovered receptors to detect, respond to light
Single-celled organisms in the open ocean use a diverse array of genetic tools to detect light, even in tiny amounts, and respond. The discovery of these new genetic “light switches” could also aid in the field of optogenetics, in which a cell’s function can be controlled with exposure to light.
Battling harmful algae blooms
In two separate studies, the University of Delaware’s Kathryn Coyne is looking at why one species of algae has some strains that can cause fish kills and others that are non-toxic, while examining an algicidal bacterium found in Delaware’s Inland Bays that could provide an environmentally-friendly approach to combatting algae blooms.
