Since studying the cause and impacts of these major events, Dr Anthony hopes that their predictable nature will lead to improved warning systems and better models for predicting stress and mortality in corals.

...Uncoupling proteins act to convert stored fat into thermal energy. In the current study the authors began by showing that mice fed a high-fat diet were markedly insulin resistant, a result of defects in insulin signaling in skeletal muscle and liver. In contrast, mice overexpressing UCP3 in skeletal muscle e...NIH awards nearly $21 million to fund cutting-edge research equipment

...e vent communities showed that life could exist on thermal and chemical energy. Since oceans have existed, more or less, since the beginning of Earth's history, these deep sea hydrothermal vents could be the most ancient sites of life on Earth. Yet the vents are not only of scientific interest, since the org...Palau's coral reefs show differential habitat recovery following the 1998 bleaching event
