Golden age of prostate cancer treatment hailed as fourth drug in two years extends life Posted: 15 Aug 2012 02:49 PM PDT Scientists have hailed a golden age in prostate cancer drug discovery as for the fourth time in two years a new drug has been found to significantly extend life. A study now shows the drug enzalutamide can significantly extend life and improve quality of life in men with advanced prostate cancer -- in findings that could further widen the treatment options for men with the disease.

Detection dogs spot northern spotted owls, even those alarmed by barred owls Posted: 15 Aug 2012 02:49 PM PDT A series of forest searches by dogs specially trained to sniff out northern spotted owl pellets -- the undigested bones, fur and other bits regurgitated by owls -- improved the probability of finding the owls by nearly 30 percent over a series of traditional vocalization surveys.

Gut bacteria linked to obesity and metabolic syndrome identified Posted: 15 Aug 2012 02:49 PM PDT Researchers have identified 26 species of bacteria in the human gut microbiota that appear to be linked to obesity and related metabolic complications. These include insulin resistance, high blood sugar levels, increased blood pressure and high cholesterol, known collectively as "the metabolic syndrome," which significantly increases an individual's risk of developing diabetes, cardiovascular disease and stroke.

Two hurricane global hawks, two sets of instruments Posted: 15 Aug 2012 01:31 PM PDT NASA's Hurricane Severe Storm Sentinel Mission, or HS3, will be studying hurricanes at the end of the summer, and there will be two high-altitude, long-duration unmanned aircraft with different instruments flying over the storms.

Exploring the two-way linkages between binge drinking and unemployment Posted: 15 Aug 2012 01:16 PM PDT Many studies have found that problem drinking is related to subsequent unemployment; However, the reverse association is unclear. Some studies have found that unemployment can increase total drinking, alcohol disorders, and/or problem drinking while others have found that unemployment can decrease drinking or have no effect at all. An analysis of binge drinking as either a predictor or outcome of unemployment has found that binge drinking among women seems to have a significant association with long-term unemployment.

Continuous oral contraceptive pills offer women earlier pain relief Posted: 15 Aug 2012 12:16 PM PDT Taking oral contraceptives continuously, rather than as traditionally prescribed for each cycle, provides earlier relief for moderate to severe menstrual cramps -- dysmenorrhea -- according to researchers at Penn State College of Medicine.

Potential hurdle to universal flu vaccine development may be overcome, study suggests Posted: 15 Aug 2012 11:20 AM PDT In the quest for a universal influenza vaccine -- one that elicits broadly neutralizing antibodies that can protect against most or all strains of flu virus -- scientists have faced a sobering question: Does pre-existing immunity generated by prior exposure to influenza virus or vaccine hamper production of broadly neutralizing antibodies? If so, then a universal flu vaccine might work best (and perhaps only) in very young children who have had limited exposure to influenza viruses or vaccines.

Blocking destruction of defective proteins unexpectedly delays neurodegeneration in mice Posted: 15 Aug 2012 11:20 AM PDT One might expect that ridding a brain cell of damaged proteins would be a universally good thing, and that impairing the cell's ability to do this would allow the faulty proteins to accumulate within the cell, possibly to toxic levels. So a lot of scientific effort has gone into looking for ways to enhance the process by which cells dispose of banged-up proteins. But this thinking may need some revision, according to a new study.

Previously unknown cleaning system in brain: Newer imaging technique brings 'glymphatic system' to light Posted: 15 Aug 2012 11:20 AM PDT A previously unrecognized system that drains waste from the brain at a rapid clip has been discovered by neuroscientists. The highly organized system acts like a series of pipes that piggyback on the brain's blood vessels, sort of a shadow plumbing system that seems to serve much the same function in the brain as the lymph system does in the rest of the body -- to drain away waste products.

This is not a pipe: Curious dark Pipe Nebula seen as never before Posted: 15 Aug 2012 05:27 AM PDT Just as René Magritte wrote "This is not a pipe" on his famous painting, this is also not a pipe. It is however a picture of part of a vast dark cloud of interstellar dust called the Pipe Nebula. By coincidence this image is appearing on the 45th anniversary of the painter's death.

Structure of superheavy elements in 'island of stability': Nucleus 256Rf can now be studied in depth Posted: 15 Aug 2012 05:27 AM PDT One of the most sought-after goals in nuclear physics is an understanding of the structure of superheavy elements in the so-called "island of stability". These nuclei contain a large number of protons, and would ordinarily be ripped apart by the strong Coulomb repulsion between them. However, quantum mechanical shell-effects act to stabilize the nuclei, meaning that they can then live long enough to be observed in the laboratory. Now, experimental advances make it possible to study the nucleus 256Rf in detail for the first time.

Flexible snake armor could inspire abrasion-resistant materials Posted: 15 Aug 2012 05:27 AM PDT Snakes are highly specialized legless animals, which have evolved around 150 million years ago. Although without extremities their body is exposed to constant friction forces. Snake skin could inspire systems in engineering with minimized abrasion.
