| Gene therapy achieves early success against hereditary bleeding disorder, study suggests Posted: 11 Dec 2011 10:44 AM PST Symptoms improved significantly in adults with the bleeding disorder hemophilia B following a single treatment with gene therapy.  |
| Multi-purpose photonic chip paves the way to programmable quantum processors Posted: 11 Dec 2011 10:40 AM PST A multi-purpose optical chip which generates, manipulates and measures entanglement and mixture -- two quantum phenomena which are essential driving forces for tomorrow's quantum computers -- has now been developed. This work represents an important step forward in the race to develop a quantum computer.  |
| Posted: 11 Dec 2011 10:40 AM PST What would be a case for the repair shop for a car engine is completely normal for a micro engine. If it sputters, this is caused by the thermal motions of the smallest particles, which interfere with its running. Researchers have now observed this with a heat engine on the micrometer scale. They have also determined that the machine does actually perform work, all things considered. Although this cannot be used as yet, the experiment shows that an engine does basically work, even if it is on the microscale. This means that there is nothing, in principle, to prevent the construction of highly efficient, small heat engines.  |
| Comprehensive view of the status of Atlantic bluefin tuna Posted: 09 Dec 2011 02:19 PM PST Bluefin populations on both sides of the Atlantic Ocean have declined precipitously since 1950, according to a new study. The model estimates the number of Atlantic bluefin tuna remaining in the ocean and projects future population sizes based on alternative management scenarios. The new model is revolutionary in its ability to account for population overlap (mixing) of this highly migratory animal on the North Atlantic foraging grounds.  |
| People with DFNA2 hearing loss show increased touch sensitivity, study shows Posted: 09 Dec 2011 07:57 AM PST People with a certain form of inherited hearing loss have increased sensitivity to low frequency vibration, according to a new study. The research findings reveal previously unknown relationships between hearing loss and touch sensitivity.  |
| Ready-to-bake cookie dough not ready-to-eat, study of E. coli outbreak finds Posted: 09 Dec 2011 07:53 AM PST The investigation of a 2009 multistate outbreak of Shiga toxin-producing Escherichia coli, an important cause of bacterial gastrointestinal illness, led to a new culprit: ready-to-bake commercial prepackaged cookie dough.  |
| New approach to management of overeating in children Posted: 07 Dec 2011 02:58 PM PST Overeating, whether in children or adults, often takes place even in the absence of hunger, resulting in weight gain and obesity. Current methods to treat such overeating in youth focus on therapies that restrict what kids may eat, requiring them to track their food intake and engage in intensive exercise. Psychiatrists are now developing new ways to treat overeating in children and adults.  |
