November 2011 Dr. Redonna K. Chandler of NIDA receives the Institute's 2011 Innovator Award for developing a method that fosters collaboration and data sharing on various studies of HIV in criminal justice populations.
November 2011 New studies show that microRNAs, snippets of RNA implicated in a wide variety of biological processes, are involved in promoting and inhibiting cocaine addiction. The findings could pave a new path for the development of anti-addiction therapies.
Individuals with weak signaling in a nicotine-sensitive brain circuit were more vulnerable to nicotine dependence than those with stronger signaling, according to a study conducted while the subjects’ brains were in a resting state. A second resting-state study finds that the same circuit appears to mediate dependence associated with a genetic risk factor for smoking.
November 2011 In a new series of studies tracing the molecular events that occur in the brain as memories are formed and preserved, researchers find that certain epigenetic changes may promote vulnerability to relapse.
