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
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
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
'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
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
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
