Collective intelligence: Number of women in group linked to effectiveness in solving difficult problems (October 2, 2010) -- Researchers document the existence of collective intelligence among groups of people who cooperate well, showing that such intelligence extends beyond the cognitive abilities of the groups' individual members, and that the tendency to cooperate effectively is linked to the number of women in a group. ... > full story
Source of breast drug side effect identified; Pharmacogenomic discovery allows for improved cancer therapy (October 2, 2010) -- Researchers have discovered genetic variants that lead to severe arthritis for a subset of women when taking aromatase inhibitors to treat their breast cancer. ... > full story
How to still kill a resistant parasite (October 2, 2010) -- Scientists in Belgium, in collaboration with colleagues from several developing countries, were able to restore a sleeping sickness parasite’s susceptibility to drugs. The parasite causes sleeping sickness in cattle. Because it has become resistant against all currently available drugs, it causes enormous economic losses. Until now, that is. ... > full story
Rebels without applause: New study on peer victimization (October 2, 2010) -- Loners and antisocial kids who reject other children are often bullied at school -- an accepted form of punishment from peers as they establish social order. Such peer victimization may be an extreme group response to control renegades, according to a new study. ... > full story
Severe food allergies turned off in mice (October 2, 2010) -- Scientists have discovered a way to turn off the immune system's allergic reaction to certain food proteins in mice, a discovery that could have implications for the millions of people who suffer severe reactions to foods, such as peanuts and milk. ... > full story
Screening tool can detect colorectal cancer from a small blood sample (October 2, 2010) -- A new microRNA screening assay detected the majority of early stage colorectal cancers with good specificity and sensitivity. ... > full story
Mosquito gene examined for new disease response (October 2, 2010) -- Researchers have searched for new genes that are turned on during infection in a type of mosquito that is not only a pest, but transmits disease-causing pathogens. ... > full story
New strategy could reduce twin rate after IVF (October 2, 2010) -- A strategy to encourage single embryo transfer after in vitro fertilization could be an important tool to prevent multiple pregnancies and their associated complications, finds a new study. ... > full story
Tanezumab reduces osteoarthritis knee pain, phase II study finds (October 2, 2010) -- Just months after a pharmaceutical company halted studies of tanezumab, a drug used in reducing pain and improving function in people with moderate-to-severe osteoarthritis of the knee, the results of a small, phase II clinical trial found only a few minor side effects and substantial improvement in patient conditions. ... > full story

The study suggests that improving prenatal sleep hygiene may provide important health benefits. ... > full story
Catalyst sandwich: Synthetic PCR mimic could lead to highly sensitive medical, environmental diagnostics (October 2, 2010) -- Researchers have taken another step towards realizing a new class of PCR enzyme mimics, opening the door for the development of highly sensitive chemical detection systems that go beyond nucleic acid targets. The blueprint for building synthetic structures to detect and signal the presence of targets such as small molecule medical analytes and environmental hazards is inspired by biology. The method also could be useful in catalysis and the production of polymers. ... > full story
Real partners are no match for ideal mate, study finds (October 2, 2010) -- Our ideal image of the perfect partner differs greatly from our real-life partner, according to new research. The research found that our actual partners are of a different height, weight and body mass index than those we would ideally choose. ... > full story
