When injected into mice immediately following a traumatic event, a new drug prevents the animals from developing memory problems and increased anxiety that are indicative of post-traumatic stress disorder (PTSD). Howard Hughes Medical Institute scientists utilized mouse studies to suggest that a receptor called Oprl1 is altered in mice with PTSD-like symptoms. They then worked with a group at the Scripps Research Institute who had previously developed the Oprl1-targeted drug to examine its effects on fear memory modulation.

Many elementary students' math performance improves when their teachers collaborate, work in professional learning communities or do both, yet most students don't spend all of their elementary school years in these settings, a new study by UNC Charlotte researchers shows. The U.S. Department of Education funded the study, which the journal Sociology of Education recently published.
Bubbles in a champagne glass may add a festive fizz, but microscopic bubbles that form in metallic glass can signal serious trouble. That’s why researchers used computer simulations to study how these bubbles form and expand.
Analyzing soil lead in an urban garden plot is important and sampling approaches may involve tradeoffs between finding ‘hotspots’ versus looking at the average amount of lead when checking for safe levels.
Many elementary students’ math performance improves when their teachers collaborate, work in professional learning communities or do both, yet most students don’t spend all of their elementary school years in these settings, a new study shows.
Strike zone judgment grows worse over the course of a Major League Baseball season in a predictable way, possibly due to the effect of grueling travel schedules, disrupted sleep patterns and fatigue, a Vanderbilt University Medical Center sleep researcher reports at a national meeting this week.
Kennedy Krieger researchers find children with co-occurrence of autism spectrum disorder and attention deficit hyperactivity disorders face greater impairments.
While aspirin has been shown to be effective in preventing heart attacks in men, it also increases the risk of gastrointestinal bleeding and possibly stroke, even at low doses. As such, national guidelines suggest that aspirin be used for prevention only in men at higher risk for cardiovascular events, so that the benefits of aspirin are greater than its adverse effects.
American entrepreneurs pray more frequently, are more likely to see God as personal and are more likely to attend services in congregations that encourage business and profit-making, according to a study by Baylor University scholars of business and sociology.
Many women get too little sleep, despite considerable evidence showing the importance of sleep to overall health. Now a new UC San Francisco study has discovered another reason why inadequate sleep may be harmful, especially to women and their hearts.
