| Posted: 02 Dec 2011 12:58 PM PST Discoveries of new planets just keep coming and coming. A team of astronomers has found 18 Jupiter-like planets in orbit around massive stars. The discoveries further constrain theories of planet formation.  |
| Instant nanodots grow on silicon to form sensing array Posted: 02 Dec 2011 12:55 PM PST Scientists have shown that it is now possible to simultaneously create highly reproductive three-dimensional silicon oxide nanodots on micrometric scale silicon films in only a few seconds. Scientists were able to create a square array of such nanodots, using regularly spaced nanoindents on the deposition layer, that could ultimately find applications as biosensors for genomics or bio-diagnostics.  |
| Vegetables, fruits, grains reduce stroke risk in women Posted: 01 Dec 2011 01:35 PM PST Swedish women who ate an antioxidant-rich diet had fewer strokes especially if they had no history of cardiovascular disease, according to a new study. The findings persisted even after statistics were adjusted for other risk factors such as smoking and physical activity. Women with the highest level of antioxidants in their diet consumed about half their antioxidants from fruits and vegetables.  |
