| Key to immune cell's 'internal guidance' system discovered Posted: 05 Feb 2012 01:38 PM PST Researchers have discovered the molecular pathway that enables receptors inside immune cells to find, and flag, fragments of pathogens trying to invade a host. The discovery of the role played by the molecule CD74 could help immunologists investigate treatments that offer better immune responses against cancers, viruses and bacteria, and lead to more efficient vaccines. |
| Genetic variant increases risk of common type stroke Posted: 05 Feb 2012 01:37 PM PST A genetic variant that increases the risk of a common type of stroke has been identified by scientists. This is one of the few genetic variants to date to be associated with risk of stroke and the discovery opens up new possibilities for treatment. |
| Early study suggests nanodiamonds safe for implants Posted: 05 Feb 2012 01:37 PM PST As the number of knee and hip joint replacements grows, nanodiamond coatings could answer problems related to metal surfaces. |
| Hearing metaphors activates brain regions involved in sensory experience Posted: 03 Feb 2012 03:26 PM PST New brain imaging research reveals that a region of the brain important for sensing texture through touch, the parietal operculum, is also activated when someone listens to a sentence with a textural metaphor. The same region is not activated when a similar sentence expressing the meaning of the metaphor is heard. |
| Scientists show positive effects of affirmative action policies promoting women Posted: 02 Feb 2012 12:17 PM PST Interventions to promote women have continuously been criticized as ineffective and inhibiting performance. Economists have now rejected this criticism; they conducted a series of experiments which examined the efficiency and effects of various interventions to increase women's willingness to enter competition. |
