| New insight into placental growth and healthy pregnancy Posted: 10 Jun 2012 12:15 PM PDT Scientists have gained a new understanding of how the growth of the placenta is regulated before birth, which has important implications for a healthy pregnancy. The research shows that the controlled release of a specific molecule, called miR-675, slows down growth of the placenta before birth.  |
| Brain scans show specific neuronal response to junk food when sleep-restricted Posted: 10 Jun 2012 12:14 PM PDT The sight of unhealthy food during a period of sleep restriction activated reward centers in the brain less active than with adequate sleep, a new study using fMRI scans shows. Previous research has shown restricted sleep leading to increased food consumption in healthy people and increased desires for sweet and salty food. Results from this study provides additional support for the role of inadequate sleep in appetite-modulation and obesity.  |
| Researchers watch tiny living machines self-assemble Posted: 10 Jun 2012 12:13 PM PDT Enabling bioengineers to design new molecular machines for nanotechnology applications is one of the possible outcomes of a new study. Scientists have developed a new approach to visualize how proteins assemble, which may also significantly aid our understanding of diseases such as Alzheimer's and Parkinson's, which are caused by errors in assembly.  |

| Four new gene loci predisposing people to the most common subtype of migraine Posted: 10 Jun 2012 12:12 PM PDT Scientists have identified four new gene loci predisposing people to the most common subtype of migraine, migraine without aura. About 2/3 of migraine sufferers belong to this group.  |
| Overwhelming evidence of hidden heart disease in hypertensive African-Americans Posted: 08 Jun 2012 01:01 PM PDT A new study has found that an overwhelming majority of African-American patients with hypertension also suffered hidden heart disease caused by high blood pressure even though they displayed no symptoms.  |
