The growing number of professional women scientists invites studies like the one conducted by Teresa Woodruff, a professor of Northwestern University’s McCormick School of Engineering, Medical Social Sciences.

“We’re very interested in understanding how team science influences quality and quantity of science,” Woodruff said. By studying different teams of scientists, Woodruff and colleagues found that teams comprised of both men and women performed better than male-only teams. Continue reading
Worldwide, one in 14 women (7.2%) aged 15 years or older report being sexually assaulted by someone other than an intimate partner at least once in their lives, according to new research published in The Lancet looking at the prevalence of non-partner sexual violence* in 56 countries.
The estimates suggest that the global picture varies widely. Countries with the highest rates of sexual violence are those in central sub-Saharan Africa (21%; Democratic Republic of Congo), southern sub-Saharan Africa (17.4%; Namibia, South Africa, Zimbabwe), and Australasia (16.4%; New Zealand and Australia). Countries in North Africa/ Middle East (4.5%; Turkey) and south Asia (3.3%; India, Bangladesh) reported the lowest rates.
