Researchers have succeeded for the first time in recording, in action, a light-driven sodium pump from bacterial cells. The findings promise progress in the development of new methods in neurobiology.

Experimental setup for a light-activated pump (center) developed by Dartmouth researchers. The blue light in the right side of the filter shows the filtration and capture of chlorides and bromides by ...

Synthetic biology is an emerging and rapidly evolving engineering discipline. Now scientists have engineered a chemically switchable version of the light-driven proton pump proteorhodopsin -- an ...

As water enters the pump, a wavelength of light activates a synthetic molecular receptor designed to bond to negatively charged ions, or anions, a class of pollutants linked to metabolic disruptions ...
