The study, using data from one of the nation's largest school districts, also shows that student class assignments vary within schools by a teacher's gender and race.

Doctors-in-training spend very little time at patient bedside, study finds Posted: 23 Apr 2013 10:57 AM PDT Medical interns spend just 12 percent of their time examining and talking with patients, and more than 40 percent of their time behind a computer, according to a new study that closely followed first-year residents at Baltimore's two large academic medical centers. Indeed, the study found, interns spent nearly as much time walking (7 percent) as they did caring for patients at the bedside.

Infants' sweat response predicts aggressive behavior as toddlers Posted: 23 Apr 2013 10:57 AM PDT Infants who sweat less in response to scary situations at age 1 show more physical and verbal aggression at age 3, according to new research.

New pathway, enhancing tamoxifen to tame aggressive breast cancer identified Posted: 23 Apr 2013 10:57 AM PDT Tamoxifen is a time-honored breast cancer drug used to treat millions of women with early-stage and less-aggressive disease, and now medical researchers have shown how to exploit tamoxifen's secondary activities so that it might work on more aggressive breast cancer.

Virus kills melanoma in animal model, spares normal cells Posted: 23 Apr 2013 10:57 AM PDT Researchers have demonstrated that vesicular stomatitis virus is highly competent at finding, infecting, and killing human melanoma cells, both in vitro and in animal models, while having little propensity to infect non-cancerous cells.
