Bacterial Vaginosis and Race: A new study out of the University of Pittsburgh School of Medicine finds that black women and women whose sexual partner is black are at a higher risk for bacterial vaginosis (BV). BV is a common vaginal infection, often characterized by a foul-smelling discharge, that puts pregnant women at an increased risk for preterm birth. One of the study’s author’s notes, “There could be genetic differences that relate to why infection rates are different, and maybe some differences in nutritional status that could play a part. But we don’t even know the differences in normal vaginal flora among racial groups…More study is definitely needed. What we can say now is that it’s just not as simple as treating the woman.”

Year-Round Schools, No Gains? A sociologist out of Ohio State University reports that children in year-round schools do not appear to learn more than those who attend on a traditional nine-month schedule. Over a full year, he found, reading and math scores improved the same amount for children in both groups. In the US, year-round schools tend to have the same number of school days as traditional ones, with vacation time spread out throughout the year. The researcher concluded, “On purely academic grounds, I wouldn’t advocate a year-round calendar, but I can’t recommend against it, either.”
