The study was conducted using high-technology eye-tracking headgear and software that measures [...]

Exposure to Bisphenol A (BPA), phthalates and flame retardants (PBDEs) are strongly associated with adverse health effects on humans and laboratory animals. A special section in the October 2008 issue of Environmental Research, “A Plastic World” provides critical new research on environmental contaminants and adverse reproductive and behavioral effects.
Plastic products contain “endocrine disrupting chemicals” that [...]

Infants who slept in a bedroom with a fan ventilating the air had a 72 percent lower risk of Sudden Infant Death Syndrome compared to infants who slept in a bedroom without a fan, according to a new study by the Kaiser Permanente Division of Research.
This is the first study to examine an association between [...]

Supporting what many of us who are not musically talented have often felt, new research reveals that trained musicians really do think differently than the rest of us.
