| Paddle vs. propeller: Which competitive swimming stroke is superior? Posted: 19 Jun 2012 08:02 PM PDT In time for the US Olympic Trials, engineers settle the argument over which swim stroke technique -- deep catch or sculling -- is faster.  |
| Hulk smash? Maybe not anymore: Scientists block excess aggression in mice Posted: 19 Jun 2012 08:01 PM PDT Pathological rage can be blocked in mice, researchers have found, suggesting potential new treatments for severe aggression, a widespread trait characterized by sudden violence, explosive outbursts and hostile overreactions to stress.  |
| Most quasars live on snacks, not large meals Posted: 19 Jun 2012 07:56 PM PDT A census of 30 quasar host galaxies, conducted with the Hubble Space Telescope and Spitzer Space Telescope, has found that black holes in the early universe may have only needed a few snacks, such as a batch of gas or the occasional small satellite galaxy, rather than one giant meal to fuel their quasars and help them grow.  |
| Mars weather report: Size of particles in Martian clouds of carbon dioxide snow calculated Posted: 19 Jun 2012 09:01 AM PDT New research shows that, much like Earth, the polar caps of Mars change with the seasons. In the dead of a Martian winter, clouds of snow blanket the Red Planet's poles -- but unlike our water-based snow, the particles on Mars are frozen crystals of carbon dioxide. Most of the Martian atmosphere is composed of carbon dioxide, and in the winter, the poles get so cold -- cold enough to freeze alcohol -- that the gas condenses, forming tiny particles of snow.  |
| From pomegranate peel to nanoparticles Posted: 19 Jun 2012 07:39 AM PDT Food waste is a growing problem in many parts of the world, but discarded fruit peel, in the case of pomegranates, could be put to good use in the burgeoning field of nanotechnology according to new research.  |
| Schooling fish: Wild zebrafish assess risk through social learning Posted: 19 Jun 2012 07:38 AM PDT Scientists have investigated whether zebrafish use social learning to assess risk. They found that wild zebrafish, which are more timid than their domesticated counterparts, became emboldened after interacting with domesticated zebrafish. The opposite did not occur, however.  |
| Belief in hell, according to international data, is associated with reduced crime Posted: 19 Jun 2012 06:32 AM PDT Religions are thought to serve as bulwarks against unethical behaviors. However, when it comes to predicting criminal behavior, the specific religious beliefs one holds is the determining factor, says a psychologist.  |
| On the origin of music by means of natural selection Posted: 18 Jun 2012 12:37 PM PDT Do away with the DJ and scrap the composer. A computer program powered by Darwinian natural selection and the musical tastes of 7,000 website users may be on the way to creating a perfect pop tune, according to new research.  |
