Sediments buried beneath the Black Sea contain ancient virus and host DNA A scientist analyzing ancient plankton DNA signatures in sediments of the Black Sea has found that the same genetic populations of a virus and its algal host can persist--and coexist--for centuries. The findings have implications for the ecological significance of viruses in shaping ecosystems in the ocean, and perhaps in fresh water. "The finding that the DNA of viruses and their algal hosts can be preserved in the...

Lack of sufficient iron may be a significant factor in controlling massive blooms of Emiliania huxleyi, a globally important species of marine algae or phytoplankton, according to research led by researchers at the National Oceanography Centre (NOC) in Southampton. Emiliania huxleyi is a species of coccolithophore found in oceans all around the world, from the tropics to the Arctic Ocean. Coccolithophore blooms often develop during the summer when a blanket of water called the thermocline...

A chemical culprit responsible for the rapid, mysterious death of phytoplankton in the North Atlantic Ocean has been found by collaborating scientists at Rutgers University and the Woods Hole Oceanographic Institution (WHOI).  This same chemical may hold unexpected promise in cancer research. The team discovered a previously unknown lipid, or fatty compound, in a virus that has been attacking and killing Emiliania huxleyi, a phytoplankton that plays a major role in the global carbon...
