Marine organisms use previously undiscovered receptors to detect, respond to light

magnified cells of various shapes arranged in a mosaic

Single-celled organisms in the open ocean use a diverse array of genetic tools to detect sunlight, 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 light exposure.

Genetic switch lets marine diatoms do less work at higher CO2

Oceanographers found the genetic ‘needles in a haystack’ to gain the first hints at how diatoms — tiny drifting algae that carry out a large part of Earth’s photosynthesis — detect and respond to increasing carbon dioxide from burning of fossil fuels.

Invisible helpers of the sea: Marine bacteria boost growth of tiny ocean algae

mosaic made out of different shaped diatoms

Using seawater collected in Seattle, Whidbey Island and other sites, UW oceanographers show that just as with plants on land, a common species of ocean diatom grows faster in the presence of helpful bacteria.

Ocean technology course ends spring quarter with a splash

students on dock

A University of Washington undergraduate class has students design, build and test their own Internet-connected oceanographic sensors. The students are getting their feet wet, literally, in a new type of oceanography.
