Most efficient quantum memory for light developed Posted: 28 Jun 2010 05:00 AM PDT An Australian-led team has developed the most efficient quantum memory for light in the world, taking us closer to a future of super-fast computers and communication secured by the laws of physics.

Accurate way to predict the age when women will hit the menopause developed Posted: 28 Jun 2010 05:00 AM PDT Researchers have developed a way of accurately predicting when women will hit the menopause using a simple blood test. The average difference between the predicted age and the actual age that the women in their study reached the menopause was only a third of a year, and the maximum margin of error was between three and four years.

Why mercury is more dangerous in oceans Posted: 28 Jun 2010 05:00 AM PDT Even though freshwater concentrations of mercury are far greater than those found in seawater, it's the saltwater fish like tuna, mackerel and shark that end up posing a more serious health threat to humans who eat them.

Technique enables precise control of protein activity in living cells Posted: 28 Jun 2010 05:00 AM PDT Researchers have developed a new technique called engineered allosteric regulation, which provides a new tool for scientists who study the interactions of proteins within living cells.

Physicists explain why superconductors fail to produce super currents Posted: 28 Jun 2010 05:00 AM PDT When high-temperature superconductors were first announced in the late 1980s, it was thought that they would lead to ultra-efficient magnetic trains and other paradigm-shifting technologies. That didn't happen. Now, physicists are helping explain why.

Do spending cuts cost lives? Posted: 28 Jun 2010 05:00 AM PDT Radical cuts to social welfare spending to reduce budget deficits could cause not just economic pain but cost lives, warn experts in a new study.

Scientists grow new lungs using 'skeletons' of old ones Posted: 28 Jun 2010 02:00 AM PDT Tissue engineers' progress toward growing new lungs for transplantation or research has long been frustrated by the problem of coaxing stem cells to develop into the varied cell types that populate different locations in the lung. Now, researchers have found a possible solution by seeding mouse embryonic stem cells into "acellular" rat lungs -- organs whose original cells have been destroyed, leaving behind empty, lung-shaped scaffolds of structural proteins.

Gestational diabetes linked to serotonin and dietary protein Posted: 28 Jun 2010 02:00 AM PDT The cause of diabetes during pregnancy is directly controlled by serotonin, a chemical produced by the body and normally known as a neurotransmitter, and is influenced by the amount of protein in the mother's diet early in pregnancy, according to new findings.

Sea ice in the Arctic not recovering: Another critical minimum forecast Posted: 28 Jun 2010 02:00 AM PDT A critical minimum for Arctic sea ice can again be expected for late summer 2010, according to new projections by researchers in Germany.

Same types of cell respond differently to stimulus, study shows Posted: 28 Jun 2010 02:00 AM PDT Using new technology that allows scientists to monitor how individual cells react in the complex system of cell signaling, researchers have uncovered a much larger spectrum of differences between each cell than ever seen before.

Carbon sequestration: Boon or burden? Posted: 28 Jun 2010 02:00 AM PDT The idea to sequester carbon is gaining support as a way to avoid global warming. For example, the European Union plans to invest billions of Euros to develop carbon capture and storage whereby carbon dioxide will be extracted and stored underground. But how effective is this procedure and what are the long-term consequences of leakage for the climate? Research has now cast light on these issues.

Healthier cafeteria food, more intense gym classes lower students' diabetes risk Posted: 28 Jun 2010 02:00 AM PDT Healthier cafeteria choices, longer and more intense periods of physical activity and robust in-school education programs can lower rates of obesity and other risk factors for type 2 diabetes, according to a national US study.

Improved telescope sees through atmosphere with pinpoint sharpness Posted: 27 Jun 2010 11:00 PM PDT A sharp view of the starry sky is difficult, because the atmosphere constantly distorts the image. A Dutch researcher has developed a new type of telescope mirror, which quickly corrects the image. His prototypes are required for future large telescopes, but also gives old telescopes a sharper view.

Antioxidants may help prevent malaria complicaton that leads to learning impairment Posted: 27 Jun 2010 11:00 PM PDT Using an experimental mouse model for malaria, scientists have discovered that adding antioxidant therapy to traditional antimalarial treatment may prevent long-lasting cognitive impairment in cerebral malaria.

Tropical biodiversity is about the neighbors Posted: 27 Jun 2010 11:00 PM PDT Rare plant species are much more negatively affected by the presence of their own species as neighbors than are common species. This may explain how biodiversity arises and is maintained.

Traditional neurologic exams inadequate for predicting survival of cardiac arrest patients Posted: 27 Jun 2010 11:00 PM PDT Traditional methods for assessing patients after cardiac arrest may be underestimating their chances for survival and good outcomes, according to a new study.

Nanowires for future electronics: Process for manufacturing nanoelectronic 'mini-circuits' developed Posted: 27 Jun 2010 11:00 PM PDT The tale begins with a feasibility study on the manufacture of colored fluorescing thin films for optical safety applications. A project on the development of novel gas sensors followed. In the meantime, researchers have successfully synthesized complex organic nanowires and managed to attach them together with electrically conducting links -- the first step towards the future production of electronic and optoelectronic components.

High rates of sexually transmitted infections among older swingers Posted: 27 Jun 2010 11:00 PM PDT Swingers -- straight couples who regularly swap sexual partners at organized gatherings and clubs and indulge in group sex -- have rates of sexually transmitted infections comparable with those of recognized high risk groups, reveals new research.

Carbon nanotubes form ultrasensitive biosensor to detect proteins Posted: 26 Jun 2010 09:00 PM PDT A cluster of carbon nanotubes coated with a thin layer of protein-recognizing polymer form a biosensor capable of using electrochemical signals to detect minute amounts of proteins, which could provide a crucial new diagnostic tool for the detection of a range of illnesses, researchers report.

Can too much HDL be harmful to women with type 1 diabetes? Posted: 25 Jun 2010 09:00 PM PDT Elevated blood levels of high-density lipoprotein (HDL) or "good" cholesterol, typically thought to protect against heart disease, may do the opposite in women with type 1 diabetes, according to new research.

Minor kidney damage in people with type 1 diabetes leads to increased mortality Posted: 25 Jun 2010 09:00 PM PDT People with type 1 diabetes who have early and asymptomatic kidney damage, as indicated by small amounts of protein in the urine, are six times more likely to die compared to the general population, according to a new study.

No heart benefit from Omega-3 in women with type 1 diabetes Posted: 25 Jun 2010 09:00 PM PDT Consuming higher amounts of omega-3 fatty acids does not appear to lower heart disease risk for women with type 1 diabetes, according to new research.
