| Researchers decode a puzzling movement disorder Posted: 24 Nov 2011 12:07 PM PST Neurodegenerative diseases represent one of the greatest challenges of our aging society. However, investigation into these diseases is made particularly difficult due to the limited availability of human brain tissue. Scientists have now taken a roundabout path: They reprogrammed skin cells from patients with a hereditary movement disorder into so-called induced pluripotent stem cells (iPS cells) and obtained functional nerve cells from them. They subsequently decoded how the disease arises.  |
| The ABCC9 of sleep: A genetic factor regulates how long we sleep Posted: 24 Nov 2011 12:02 PM PST Researchers have shown that ABCC9, a known genetic factor in heart disease and diabetes, also influences the duration of sleep in humans. This function is evolutionarily conserved as knock-out of the gene reduces the duration of nocturnal sleep in fruitflies.  |
| Development of the brain network in the fetus now measurable for the first time in the womb Posted: 24 Nov 2011 12:02 PM PST Scientists have demonstrated for the first time ever that there are fetal brain developments that can be measured using functional magnetic resonance tomography in the womb. This means that pathological changes to brain development will be detectable earlier than they are currently - and appropriate measures can be taken in good time.  |
| Scientists turn on fountain of youth in yeast Posted: 23 Nov 2011 04:04 PM PST Researchers have successfully manipulated the life span of common, single-celled yeast organisms by figuring out how to remove and restore protein functions related to yeast aging.  |
| Possible therapy for radiation sickness identified Posted: 23 Nov 2011 12:19 PM PST Researchers found a combination of two drugs may alleviate radiation sickness in people who have been exposed to high levels of radiation, even when the therapy is given 24 hours after the exposure occurred.  |
| Happy, feel-good holiday seasons start with healthy choices at Thanksgiving, nutrition experts say Posted: 22 Nov 2011 10:30 AM PST While most people only gain about a pound of weight during the holiday season, that pound may never come off, increasing the likelihood of becoming overweight or obese and the risk of related health problems, according to a recent study. Dietitians recommend families maintain healthy diet and exercise habits during the holiday season beginning with Thanksgiving.  |
