Morning Sickness Associated with Lower Miscarriage Risk

During the first trimester of pregnancy, many women experience what’s commonly known as “morning sickness.” As distressing as this nausea and vomiting can be, a team of NIH researchers has gathered some of the most convincing evidence to date that such symptoms may actually be a sign of something very positive: a lower risk of miscarriage.
In fact, when the researchers studied a group of women who had suffered one or two previous miscarriages, they found that the women who felt nauseous during their subsequent pregnancies were 50 to 75 percent less likely to miscarry than those without nausea. While it’s not yet exactly clear what’s going on, the findings lend support to the notion that morning sickness may arise from key biological factors that reflect an increased likelihood of a successful pregnancy.
Creative Minds: Exploring the Health Effects of Fracking

Elaine Hill
A few years ago, Elaine Hill was a doctoral student in applied economics at Cornell University in Ithaca, NY, studying maize markets in Uganda [1] and dairy supply chains in the northeastern U.S [2]. But when fracking—a controversial, hydraulic fracturing technique used to produce oil and natural gas—became a hot topic in the Finger Lakes region of upstate New York, Hill was motivated to shift gears.
After watching a documentary about fracking, Hill decided to search for scientific evidence on its possible health effects, but found relatively little high-quality data. So, she embarked on a new project—one that eventually earned her a Ph.D.—to evaluate what, if any, impact fracking has on infant and child health. Now, supported by a 2015 NIH Director’s Early Independence Award, Hill is pursuing this line of research further as an assistant professor of Public Health Sciences at the University of Rochester School of Medicine and Dentistry, Rochester, NY.
