| Posted: 02 Mar 2012 05:29 AM PST Scientists have discovered a key enzyme structure in bacteria, a finding that lays the foundation for a new generation of antibiotics that are safer and less prone to drug resistance.  |
| Older adults who sleep poorly react to stress with increased inflammation Posted: 01 Mar 2012 07:37 AM PST Older adults who sleep poorly have an altered immune system response to stress that may increase risk for mental and physical health problems, according to a new study. In the study, stress led to significantly larger increases in a marker of inflammation in poor sleepers compared to good sleepers -- a marker associated with poor health outcomes and death.  |
| Drug offers relief for symptoms of myelofibrosis, according to multisite study Posted: 01 Mar 2012 05:42 AM PST People with a blood cancer -- myelofibrosis -- can benefit from a drug called ruxolitinib, according to a randomized, double-blind, placebo-controlled clinical trial.  |
| How E. coli bacteria hijack cells' directional mechanism Posted: 01 Mar 2012 05:41 AM PST Working in the emerging field of systems biology, researchers mathematically predicted how bacteria that cause food poisoning hijack a cell's sense of direction and then confirmed those predictions in living cells.  |
