| Climate change will upset vital ocean chemical cycles Posted: 08 Sep 2013 10:57 AM PDT New research shows that rising ocean temperatures will upset natural cycles of carbon dioxide, nitrogen and phosphorus. Plankton plays an important role in the ocean's carbon cycle by removing half of all CO2 from the atmosphere during photosynthesis and storing it deep under the sea. New findings reveal that water temperature has a direct impact on maintaining the delicate plankton ecosystem of our oceans.  |
| Synthetic mRNA can induce self-repair and regeneration of the infarcted heart Posted: 08 Sep 2013 10:56 AM PDT Scientists have taken a major step towards treatment for heart attack, by instructing the injured heart in mice to heal by expressing a factor that triggers cardiovascular regeneration driven by native heart stem cells. The study also shows that there was an effect on driving the formation of a small number of new cardiac muscle cells.  |
