Endometriosis Risk Linked to Two Pesticides
A Fred Hutchinson Cancer Research Center-led study has found that two organochlorine pesticides are associated with an increased risk of endometriosis, a condition that affects up to 10 percent of reproductive-age women. Specifically, researchers observed that women with higher exposures to two such pesticides, beta-hexachlorocyclohexane and mirex, had a 30- to 70-percent increase in endometriosis risk. NewsWise
Well: A Baby’s Gaze May Signal Autism, Study Finds
Scientists are reporting the earliest behavioral sign to date that a child is likely to develop autism: when and how long a baby looks at other people’s eyes. In a study published Wednesday, researchers using eye-tracking technology found that 3-year-olds diagnosed with autism looked less at people’s eyes when they were babies than children who did not develop autism.

Hormone levels in women using contraception affect nerve activity involved in vessel constriction After menopause, women's levels of estrogen and progesterone fall. Their formerly lower risk for heart disease equals, even surpasses, men's risk. One possible contributing explanation for the change in risk is that sex hormones affect the sympathetic nervous system (SNS), which controls constriction of blood vessels and participates in the fight or flight response.
