Ocean's color affects hurricane paths (August 14, 2010) -- A change in the color of ocean waters could have a drastic effect on the prevalence of hurricanes, new research indicates. In a simulation of such a change in one region of the North Pacific, the study finds that hurricane formation decreases by 70 percent. ... > full story
Expensive new blood pressure meds no better than generics, according to long-term data (August 14, 2010) -- Expensive brand-name medications to lower blood pressure are no better at preventing cardiovascular disease than older, generic diuretics, according to new long-term data from the landmark ALLHAT study. ... > full story
Scientists clarify structural basis for biosynthesis of mysterious 21st amino acid (August 14, 2010) -- Researchers in Japan have clarified the structural basis for the biosynthesis of selenocysteine (Sec), an amino acid whose encoding mechanism offers clues about the origins of the genetic alphabet. The findings deepen our understanding of protein synthesis and lay the groundwork for advances in protein design. ... > full story
New approach which can help to predict neurodegenerative diseases (August 14, 2010) -- New research by scientists in Spain offers hope for predicting neurodegenerative diseases such as amyotrophic lateral sclerosis (ALS). Researchers have described, for the first time, the structure of a protein known as Vps54, one of the four making up the GARP complex of proteins. ... > full story
Nano world of Shrinky Dinks: Low-cost nanopatterning method utilizes popular shrinkable plastic (August 14, 2010) -- The magical world of Shrinky Dinks -- an arts and crafts material used by children since the 1970s -- has taken up residence in a Northwestern University laboratory. A team of nanoscientists is using the flexible plastic sheets as the backbone of a new inexpensive way to create, test and mass-produce large-area patterns on the nanoscale. Anyone needing access to these patterns on the cheap could benefit from this method, known as solvent-assisted nanoscale embossing. ... > full story
Happy employees may be the key to success for organizations (August 14, 2010) -- When a JetBlue flight attendant creatively deplaned earlier this week, many questions arose as to why someone would be willing to give up a steady paycheck during these tough economic times. While this "working man's hero" will most likely be questioning his motives as he hands over his lawyer's fees, a new report in Perspectives on Psychological Science, suggests that his action may be a sign of trouble for JetBlue and other large companies. ... > full story
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
