| Galaxy goes green in burning stellar fuel Posted: 23 Apr 2013 12:37 PM PDT Astronomers have spotted the "greenest" of galaxies, one that converts fuel into stars with almost 100-percent efficiency. The findings come from NASA's Wide-field Infrared Survey Explorer (WISE), NASA's Hubble Space Telescope and the IRAM Plateau de Bure interferometer in the French Alps. |
| Hundreds of tiny untethered surgical tools deployed in first animal biopsies Posted: 23 Apr 2013 10:58 AM PDT Using swarms of untethered grippers, each as small as a speck of dust, engineers and physicians have devised a new way to perform biopsies that could provide a more effective way to access narrow conduits in the body as well as find early signs of cancer or other diseases. |
| Infants' sweat response predicts aggressive behavior as toddlers Posted: 23 Apr 2013 10:57 AM PDT Infants who sweat less in response to scary situations at age 1 show more physical and verbal aggression at age 3, according to new research. |
| Contact killing of Salmonella by human fecal bacteria Posted: 23 Apr 2013 08:08 AM PDT Researchers have recently found a novel mode of interaction between Salmonella, a foodborne pathogen, and the bacteria that live in our guts. Fecal bacteria collected from healthy donors effectively inactivated Salmonella, when they were allowed close contact. Mathematical modelling of this interaction is now being used to find new ways of controlling Salmonella. |

| Decoding touch: Rats detect textures with their whiskers Posted: 23 Apr 2013 06:09 AM PDT With their whiskers rats can detect the texture of objects in the same way as humans do using their fingertips. A new study shows that it is possible to understand what specific object has been touched by a rat by observing the activation of brain neurons. A further step towards understanding how the brain, also in humans, represents the outside world. |
