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
Implantable silk metamaterials could advance biomedicine, biosensing (August 13, 2010) -- Researchers have fabricated and characterized the first large-area metamaterial structures patterned on implantable, bio-compatible silk substrates. The antenna-like devices can monitor the "fingerprints" of chemical and biological agents and might be implanted to signal changes in the body. Metamaterials are artificial electromagnetic composites whose structures respond to electromagnetic waves in ways that atoms in natural materials do not. ... > full story
Chronic myeloid leukemia: New lab test could identify imatinib resistance (August 13, 2010) -- Scientists in Japan may have developed a way to accurately predict those patients who will resist treatment with imatinib, which is the standard of care for chronic myeloid leukemia. ... > 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
'Fused' people eager to die and kill for their group, research shows (August 13, 2010) -- People with extremely strong ties to their countries or groups are not only willing, but eager, to sacrifice themselves to save their compatriots, according to new psychology research. ... > 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
Acetaminophen use in adolescents linked to doubled risk of asthma (August 13, 2010) -- New evidence linking the use of acetaminophen to development of asthma and eczema suggests that even monthly use of the drug in adolescents may more than double risk of asthma in adolescents compared to those who used none at all; yearly use was associated with a 50 percent increase in the risk of asthma. ... > full story
Magnetic molecular machines deliver drugs to unhealthy cells (August 13, 2010) -- Researchers have developed a completely novel and noninvasive method of releasing drugs remotely into the cells. The method involves a novel material using porous silica nanoparticles, and molecular machines which can be attached to contain drug molecules in the pores until a magnetic field stimulus allows the molecules to be delivered into cells. ... > 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
Trusting people make better lie detectors (August 13, 2010) -- Trusting others may not make you necessarily a fool or a Pollyanna, according to a new study. Instead, it can be a sign that you're smart. ... > full story
