| Earth's wobble 'fixes' dinner for marine organisms Posted: 13 Sep 2013 04:51 PM PDT The cyclic wobble of the Earth on its axis controls the production of a nutrient essential to the health of the ocean, according to a new study. The discovery of factors that control this nutrient, known as "fixed" nitrogen, gives researchers insight into how the ocean regulates its own life-support system, which in turn affects the Earth's climate and the size of marine fisheries.  |
| Assumptions about origins of life challenged Posted: 13 Sep 2013 03:58 PM PDT Before there was life on Earth, there were molecules. A primordial soup. At some point a few specialized molecules began replicating. This self-replication, scientists agree, kick-started a biochemical process that would lead to the first organisms. But exactly how that happened -- how those molecules began replicating -- has been one of science's enduring mysteries. Biochemists now offer an intriguing new view on how life began.  |
| Spider silk coated with carbon nanotubes has multiple surprising uses Posted: 13 Sep 2013 03:58 PM PDT Physicists have discovered that simple methods can result in surprising and environmentally friendly high-tech outcomes during their experiments with spider silk and carbon nanotubes. Spider silk coated with nanotubes can act as a humidity sensor, a strain sensor, an actuator (a device that acts as an artificial muscle, for lifting weights and more) and as an electrical wire, according to researchers.  |
| 'Grassroots action' in livestock feeding to help curb global climate change Posted: 13 Sep 2013 07:18 AM PDT Scientists offer new evidence that a potent chemical mechanism operating in the roots of a tropical grass used for livestock feed has enormous potential to reduce greenhouse gas emissions.  |
