Brief exposure to performance-enhancing drugs may be permanently 'remembered' by muscles Posted: 27 Oct 2013 05:56 PM PDT Brief exposure to anabolic steroids may have long lasting, possibly permanent, performance-enhancing effects, shows a new study.

Eleven new genetic susceptibility factors for Alzheimer's disease discovered through the largest study Posted: 27 Oct 2013 03:53 PM PDT The largest international study ever conducted on Alzheimer's disease (AD), the I-GAP (International Genomics Alzheimer's Project) consortium has identified 11 new regions of the genome involved in the onset of this neurodegenerative disease. This study gives an overview of the molecular mechanisms underlying the disease, opening up to a better understanding of the pathophysiology of AD.

New material for quantum computing discovered out of the blue Posted: 27 Oct 2013 03:52 PM PDT A common blue pigment used in the £5 note could have an important role to play in the development of a quantum computer, according to a new article.

Cell nucleus protein in brown fat cells governs daily control of body temperature Posted: 27 Oct 2013 03:50 PM PDT Body temperature follows a 24-hour rhythm, peaking during the day, low at night. The benefit might be the conservation of energy while sleeping. It is also critical to be able to adapt to changes in ambient temperature regardless of the time of day. A new mouse study shows how body temperature rhythms are synchronized while maintaining the ability to adapt to changes in environmental temperature day or night.

Scientists eye longer-term forecasts of U. S. heat waves Posted: 27 Oct 2013 03:50 PM PDT Scientists have fingerprinted a distinctive atmospheric wave pattern high above the Northern Hemisphere that can foreshadow the emergence of summertime heat waves in the United States more than two weeks in advance. The new research could potentially enable forecasts of the likelihood of U.S. heat waves 15-20 days out, giving society more time to prepare for these often-deadly events.

Smart neurons: Single neuronal dendrites can perform computations Posted: 27 Oct 2013 11:06 AM PDT When you look at the hands of a clock or the streets on a map, your brain is effortlessly performing computations that tell you about the orientation of these objects. New research has shown that these computations can be carried out by the microscopic branches of neurons known as dendrites, which are the receiving elements of neurons.

Novel mutations define two types of bone tumor: Two related genes underlie the development of two rare bone tumors in nearly 100 per cent of patients Posted: 27 Oct 2013 11:06 AM PDT Scientists have made a rare discovery that allows them to attribute two types of tumour almost entirely to specific mutations that lie in two related genes.

Radioactive waste: Where to put it? Posted: 27 Oct 2013 11:06 AM PDT As the U.S. makes new plans for disposing of spent nuclear fuel and other high-level radioactive waste deep underground, geologists are key to identifying safe burial sites and techniques. Scientists are describing the potential of shale formations; challenges of deep borehole disposal; and their progress in building a computer model to help improve understanding of the geologic processes that are important for safe disposal of high-level waste. In the United States, about 70,000 metric tons of spent commercial nuclear fuel are located at more than 70 sites in 35 states.

Hurricane Sandy's lessons include: Put parks, not houses, on the beach Posted: 27 Oct 2013 09:35 AM PDT Just days before Hurricane Sandy hit the New York and New Jersey coastline on Oct. 29, 2012, scientists had produced the most detailed model to date of the region's potential for damage from big storms.

Flash floods and debris flows: How to manage nature's runaway freight trains Posted: 27 Oct 2013 09:35 AM PDT Last month's torrential rains and flooding in Colorado made headlines, but there's another, far more common and growing weather-related threat western states are facing in the wake of longer and worsening fire seasons: flash floods and debris flows. These runaway freight trains made of rock, mud, and water can barrel down mountain channels with little or no warning and take out roads, homes, and anything else in their path.

Stroke prevention surgery less effective than meds, lifestyle change Posted: 26 Oct 2013 01:49 PM PDT The final results of a stroke prevention study in patients with narrowed brain arteries confirm earlier findings: Medication plus lifestyle changes are safer and more effective at preventing stroke than a surgical technique called stenting.

Only 11 percent of children involved in bike accidents wear a helmet Posted: 26 Oct 2013 06:11 AM PDT Despite a California bike helmet mandate, only 11 percent of Los Angeles County children treated for bike-related injuries were wearing a helmet, according to new research.

Pediatric musculoskeletal MRSA infections on the rise Posted: 26 Oct 2013 06:11 AM PDT Pediatric musculoskeletal Staphylococcus aureus bacterial infections have been evolving over the past decade, with more children diagnosed with the more virulent, methicillin-resistant Staphylococcus aureus (MRSA) today than 10 years ago. The result is longer hospitals stays, more surgeries and other related complications, according to new research.

Enzyme restores function with diabetic kidney disease Posted: 25 Oct 2013 03:56 PM PDT Researchers say that, while a prevailing theory suggests elevated cellular levels of glucose ultimately result in diabetic kidney disease, the truth may, in fact, be quite the opposite. The findings could fundamentally change understanding of how diabetes-related diseases develop – and how they might be better treated.

Surprises discovered in decoded kiwifruit genome Posted: 25 Oct 2013 12:52 PM PDT A new study that decoded the DNA sequence of the kiwifruit has concluded that the fruit has many genetic similarities between its 39,040 genes and other plant species, including potatoes and tomatoes. The study also has unveiled two major evolutionary events that occurred millions of years ago in the kiwifruit genome.

Positive personal growth following breast cancer diagnosis Posted: 25 Oct 2013 12:52 PM PDT Although being diagnosed with breast cancer is usually an extremely stressful experience for most women, a new study by researchers has found that there also can be unexpected benefits.

Measuring blood sugar with light Posted: 25 Oct 2013 09:30 AM PDT One key to healthful living with diabetes is monitoring sugar levels to ensure they remain stable. People can easily do this at home using devices that read sugar levels in a drop of blood. Now a team of researchers has devised a non-invasive way to make monitoring easier. Using infrared laser light applied on top of the skin, they measure sugar levels in the fluid in and under skin cells to read blood sugar levels.

Study reveals first effective medicine to treat cocaine dependence Posted: 25 Oct 2013 08:37 AM PDT New research reveals that topiramate, a drug approved by the U.S. Food and Drug Administration to treat epilepsy and migraine headaches also could be the first reliable medication to help treat cocaine dependence.
