| Protein That Enhances Long-term Memory By Controlling Rest Intervals Identified
October 3, 2009 at 11:00 am
|
| Repeated learning sessions produce long-lasting memory when they are spaced out between rest intervals. Neuroscientists have discovered that this so-called "spacing effect" is controlled in the brain by a molecular timer -- a protein that determines how long rest intervals need to last for long-term memory to form. |
| New Study Resolves The Mysterious Origin Of Merkel Cells

| Leg Movement Training In Preterm Infants Demonstrates Positive Changes In Motor Skills
October 3, 2009 at 11:00 am
|
| Preterm infants who receive leg movement training display feet-reaching behaviors similar to that of full-term infants, according to a randomized controlled trial. This finding supports feet-reaching play as an early intervention strategy to encourage interaction with physical objects in preterm infants who have movement problems within the first months of postnatal life. |
| Scientists Discover What Makes The Same Type Of Cells Different

|
| Scientists have managed to decipher a well-known phenomenon that had, until now, remained unexplained: why cells of the same type can react differently, and what the reason for this is. |
| Coral Bleaching Increases Chances Of Coral Disease
October 3, 2009 at 5:00 am
|
| Mass coral bleaching has devastated coral colonies around the world for almost three decades. Now scientists have found that bleaching can make corals more susceptible to disease and, in turn, coral disease can exacerbate the negative effects of bleaching. A new article shows that when they occur together, this combination of afflictions causes greater harm to corals than either does on its own. |
| Anterior Cruciate Ligament Reconstruction: Tears Common And Additional Surgery Likely In Teens
October 3, 2009 at 5:00 am
|
| Patients who have their anterior cruciate ligament reconstructed are more likely to have subsequent knee surgery if they are women or are treated by a surgeon who does a low volume of ACL reconstructions, according to a new study. The study also found that overall, 6.5 percent of patients undergoing ACL surgery had to undergo another knee operation within one year. |

| "Augmented reality" involves mixing the real world with computer-generated images. The result is a kind of visual Walkman, developed by a researcher in The Netherlands. |
| Researchers Develop An Integrated Treatment For Veterans With Chronic Pain And Posttraumatic Stress
October 3, 2009 at 5:00 am
|
| The wars in Iraq and Afghanistan have resulted in a growing number of soldiers evacuated to the United States for comprehensive care for physical and psychological trauma. Given the number of physical injuries often experienced by soldiers, it is not surprising that chronic pain is a frequent problem among returning soldiers from Operation Iraqi Freedom and Operation Enduring Freedom. | | |
