Diversity training programs lead people to believe that work environments are fair even when given evidence of hiring, promotion or salary inequities, according to new findings by psychologists at the University of Washington and other universities.
The study also revealed that participants, all of whom were white, were less likely to take discrimination complaints seriously against companies who had diversity programs. (more…)
The Stress Gradient Hypothesis holds that as stress increases in an ecosystem, mutually supportive interactions become more significant and negative interactions, such as competition, become less so. The idea has been hotly debated but is now backed by a review of hundreds of studies co-authored in Ecology Letters by Mark Bertness, professor of biology at Brown, who first formally proposed the hypothesis in 1994. The time has come, he said, to test its application and predictive value.
PROVIDENCE, R.I. [Brown University] — Ecology is rife with predation, competition, and other dramatic “negative interactions,” but those alone do not determine the course life on Earth. Organisms sometimes benefit each other, too, and according to the Stress Gradient Hypothesis, their “positive interactions” become measurably more influential when ecosystems become threatened by conditions such as drought. Ecologists have argued about the hypothesis ever since Brown University ecologist Mark Bertness co-proposed it in 1994; Bertness says a large new global meta-analysis he co-authored in Ecology Letters definitively shows that it is true.

Groundbreaking research by a team of UCLA physicians and engineers demonstrates that prostate cancer — long identifiable only through painful, hit-or-miss biopsies — can be diagnosed far more easily and accurately using a new image-guided, targeted biopsy procedure.
Traditionally, prostate tumors have been found through so-called blind biopsies, in which tissue samples are taken systematically from the entire prostate in the hopes of locating a piece of tumor — a technique that dates back to the 1980s. But the cancer now appears detectable by direct sampling of tumor spots found using magnetic resonance imaging, or MRI, in combination with real-time ultrasound, the researchers say. (more…)
New images from the Planck mission show previously undiscovered islands of star formation and a mysterious haze of microwave emissions in our Milky Way galaxy. The views give scientists new treasures to mine and take them closer to understanding the secrets of our galaxy.
Planck is a European Space Agency mission with significant NASA participation. (more…)
