Human noise pollution in ocean can lead fish away from good habitats and off to their death (August 13, 2010) -- The growing amount of human noise pollution in the ocean could lead fish away from good habitat and off to their death. ... > full story
New sporadic prion protein disease: Variably protease-sensitive prionopathy shares genotype characteristics with Creutzfeldt-Jakob (August 13, 2010) -- A new sporadic prion protein disease has been discovered. Variably protease-sensitive prionopathy, as it has been named, is the second type of complete sporadic disease to be identified since Creutzfeldt-Jakob disease was reported in the 1920s. ... > full story
New nanoscale transistors allow sensitive probing inside cells (August 13, 2010) -- Chemists and engineers have fashioned nanowires into a new type of V-shaped transistor small enough to be used for sensitive probing of the interior of cells. The new device is smaller than many viruses and about one-hundredth the width of the probes now used to take cellular measurements, which can be nearly as large as the cells themselves. ... > full story
Extended solar minimum linked to changes in sun's conveyor belt (August 13, 2010) -- A new analysis of the unusually long solar cycle that ended in 2008 suggests that one reason for the long cycle could be a stretching of the sun's conveyor belt, a current of plasma that circulates between the sun's equator and its poles. The results should help scientists better understand the factors controlling the timing of solar cycles and could lead to better predictions. ... > full story
Selected cells from blood or bone marrow may provide a route to healing blood vessels (August 13, 2010) -- When envisioning cell therapy for cardiovascular disease, a team of scientists is focusing on cells that nourish blood vessels, rather than on rare stem cells. In experiments with mice, CD31 positive cells from the blood or bone marrow can effectively treat hindlimb ischemia -- a model of peripheral artery disease. This approach has the potential to be safer and less arduous than experimental therapies involving the isolation of stem cells from bone marrow. ... > full story
Fires around Moscow: Satellite perspective reveals startling images of massive smoke clouds (August 13, 2010) -- Space scientists in the UK have released satellite images of vast plumes of smoke emanating from the peat bog fires which are currently sweeping across central and western Russia. ... > full story
Immune system overreaction may enable recurrent urinary tract infections (August 13, 2010) -- The immune system may open the door to recurrent urinary tract infections by overdoing its response to an initial infection, researchers have found. ... > full story
Industrial production of biodiesel feasible within 15 years, researchers predict (August 13, 2010) -- Within 10 to 15 years, it will be technically possible to produce sustainable and economically viable biodiesel from micro-algae on a large scale. Technological innovations during this period should extend the scale of production by a factor of three, while at the same time reducing production costs by 90%. Two researchers from the Netherlands believe this to be possible. ... > full story
Antibiotics for the prevention of malaria (August 13, 2010) -- If mice are administered an antibiotic for three days and are simultaneously infected with malaria, no parasites appear in the blood and life-threatening disease is averted. In addition, the animals treated in this manner also develop robust, long-term immunity against subsequent infections, according to new research. ... > full story
Shared phosphoproteome links remote plant species (August 13, 2010) -- Researchers have shown that even the most widely-varying species of plants share remarkable similarities in the composition of proteins in them that undergo phosphorylation, a regulatory mechanism involved in various cellular phenomena. A database released by the group, with information on over three thousand phosphorylated proteins and phosphorylation sites in rice, opens new doors in the study and engineering of plants. ... > full story
Federal nuclear waste panel overlooks public mistrust, experts say (August 13, 2010) -- According to 16 social science researchers from across the country, a renewed federal effort to fix the nation's stalled nuclear waste program is focusing so much on technological issues that it fails to address the public mistrust hampering storage and disposal efforts. ... > full story
Scientists test Australia's Moreton Bay as coral 'lifeboat' (August 13, 2010) -- An international team of scientists has been exploring Australia's Moreton Bay, close to Brisbane, as a possible 'lifeboat' to save corals from the Great Barrier Reef at risk of extermination under climate change. In a new research paper, they say that corals have been able to survive and flourish in the Bay, which lies well to the south of the main GBR coral zones, during about half of the past 7000 years. ... > full story
