For the past 2.5 million years, the Earth has experienced millennia-long cold and warm cycles that collectively have become known as the Ice Age. During cold periods, continental-scale ice sheets blanketed large tracts of the…

“We could not predict that prolonged fasting would have such a remarkable effect in promoting stem cell-based regeneration of the hematopoietic system,” said Valter Longo, corresponding author of a recent study in <em>Cell Stem Cell</em>. Photo by Dietmar Quistorf.

The Benefits of Fasting

June 10, 2014

In the first evidence of a natural intervention triggering stem cell-based regeneration of an organ or system, a study in the June 5 issue of Cell Stem Cell shows that cycles of prolonged fasting not only protect against…

Plunging into the Red Sea

May 22, 2014

Sailing across the Red Sea, USC Dornsife’s Douglas Capone and Linda Duguay hoped to get an up-close view of the reddish blooms created by cyanobacteria, which give the water its distinctive, eponymous hue. “The…

Doug Capone's research looks at the role and importance of marine microbes in major biogeochemical cycles, particularly those of nitrogen and carbon. In particular, he has shown nitrogen fixation — the process by which nitrogen is converted to ammonia — to be a key biogeochemical process in several marine ecosystems. Photo by by Taylor Faust.
