An international team of biologists led by Indiana University's David M. Kehoe has identified both the enzyme and molecular mechanism critical for controlling a chameleon-like process that allows one of the world's most abundant ocean phytoplankton, once known as blue-green algae, to maximize light harvesting for photosynthesis.

Scientists at the Carnegie Institution's Department of Plant Biology have found that photosynthetic bacteria living in scalding Yellowstone hot springs have two radically different metabolic identities. As the sun goes down, these cells quit their day job of photosynthesis and unexpectedly begin to fix nitrogen, converting nitrogen gas (N2) into compounds that are useful for cell growth.
