Patients with traumatic brain injuries are not benefiting from recent advances in cognitive neuroscience research – and they should be, scientists report in a special issue of Current Opinion in Behavioral Sciences.
A new study of teenagers and their moms reveals how adolescent brains negotiate risk – and the factors that modulate their risk-taking behind the wheel.
Two studies in mice add to the evidence that the phthalate DEHP, a plasticizing agent used in auto upholstery, baby toys, building materials and many other consumer products, can undermine female reproductive health, in part by disrupting the growth and function of the ovaries.
When scientists exposed pregnant mice to levels of bisphenol A equivalent to those considered safe in humans, three generations of female mouse offspring experienced significant reproductive problems, including declines in fertility, sexual maturity and pregnancy success, the scientists report in the journal Toxicology and Applied Pharmacology.
Scientists have found a signal in the brain that reflects young children’s aversion to members of the opposite sex (the “cooties” effect) and also their growing interest in opposite-sex peers as they enter puberty. These two responses to members of the opposite sex are encoded in the amygdala, the researchers report.
An ancient human skull and a jawbone found a few meters apart in a cave in northern Laos add to the evidence that early modern humans were physically quite diverse, researchers report in PLOS ONE.
