| Structure of ‘salvia’ receptor solved Posted: 21 Mar 2012 11:20 AM PDT A research team has determined the structure of the kappa-opioid receptor—site of action of the widely abused hallucinogen Salvia divinorum – solving longstanding scientific mysteries and offering new insights for treating drug addiction, chronic pain and depression.  |
| Marijuana-like chemicals inhibit human immunodeficiency virus (HIV) in late-state AIDS Posted: 20 Mar 2012 04:52 PM PDT Marijuana-like chemicals trigger receptors on human immune cells that can directly inhibit a type of human immunodeficiency virus (HIV) found in late-stage AIDS, research suggests.  |
| Speed of single-molecule measurements greatly increased Posted: 18 Mar 2012 11:39 AM PDT Engineers have devised a way to measure nanopores -- tiny holes in a thin membrane that can detect single biological molecules such as DNA and proteins -- with less error than can be achieved with commercial instruments. They've miniaturized the measurement by designing a custom integrated circuit using commercial semiconductor technology.  |
