| Human brain treats prosthetic devices as part of the body Posted: 06 Mar 2013 07:11 PM PST People with spinal cord injuries show a strong association of wheelchairs as part of their body, not an extension of immobile limbs. The human brain can learn to treat relevant prosthetics as a substitute for a non-working body part, according to new research.  |
| Flip of a single molecular switch makes an old mouse brain young Posted: 06 Mar 2013 10:42 AM PST The flip of a single molecular switch helps create the mature neuronal connections that allow the brain to bridge the gap between adolescent impressionability and adult stability. Now researchers have reversed the process, recreating a youthful brain that facilitated both learning and healing in the adult mouse.  |
| Robotic fish gain new sense: Navigate water currents and turbulence Posted: 06 Mar 2013 05:42 AM PST Scientists have developed robots with a new sense -- lateral line sensing. All fish have this sensing organ but so far it had no technological counterpart on human-made underwater vehicles.  |
| Curtains down for the black hole firewall paradox: Making gravity safe for Einstein again Posted: 06 Mar 2013 05:41 AM PST Scientists have revealed new insights into the life and death of black holes. Their findings dispel the so-called firewall paradox which shocked the physics community when it was announced in 2012 since its predictions about large black holes contradicted Einstein's crowning achievement -- the theory of general relativity. Those results suggested that anyone falling into a black hole would be burned up as they crossed its edge -- the so-called event horizon.  |
| Females butterflies can smell if a male butterfly is inbred Posted: 05 Mar 2013 05:04 PM PST The mating success of male butterflies is often lower if they are inbred. But how do female butterflies know which males to avoid? New research reveals that inbred male butterflies produce significantly less sex pheromones, making them less attractive to females.  |
| Handedness in marsupials is dependent on gender, research shows Posted: 05 Mar 2013 05:03 PM PST Boys are right-handed, girls are left ... Well at least this is true for sugar gliders (Petaurus breviceps) and grey short-tailed opossums (Monodelphis domestica). New research shows that handedness in marsupials is dependent on gender. This preference of one hand over another has developed despite the absence of a corpus collosum, the part of the brain which in placental mammals allows one half of the brain to communicate with the other.  |
