Jefferson scientists uncover role of cancer stem cell marker: controlling gene expression
Scientists at Jefferson's Kimmel Cancer Center in Philadelphia have made an extraordinary advance in the understanding of the function of a gene previously shown to be part of an 11-gene "signature" that can predict which tumors will be aggressive and likely to spread. view more (2008-01-18)
Self-monitoring helps reduce high-risk behavior among HIV-positive people
There are many effective, albeit expensive, intervention programs aimed at encouraging HIV-positive people to practice less risky behavior.

Caltech researchers train computers to analyze fruit-fly behavior
Scientists at the California Institute of Technology (Caltech) have trained computers to automatically analyze aggression and courtship in fruit flies, opening the way for researchers to perform large-scale, high-throughput screens for genes that control these innate behaviors. view more (2009-04-09)
Behavior modification could ease concerns about nanoparticles
In an advance that could help ease health and environmental concerns about the emerging nanotechnology industry, scientists are reporting development of technology for changing the behavior of nanoparticles in municipal sewage treatment plants - their main gateway into the environment. view more (2009-11-12)

New tool taps drool for clues to childhood stress
In four separate studies of mothers and their infants, preschoolers, kids and teens, a multi-university research team has shown, for the first time, that a simple test of a little drool can provide new insight into the role of social stressors, including relationships with parents and teachers, in child development. view more (2006-04-20)
New behavior may use old genes
Though you may not be able to teach an old dog new tricks, ASU researchers have found that evolution may have taught old genes new tricks in the development of social behavior in honeybees. view more (2006-10-26)
