Perhaps It's Still an Old Boy Network

In The Guardian, there's a story about women leaving science faster, and in larger numbers, than men. A study for the Royal Society of Chemistry found that although 72 percent of the women surveyed planned to pursue a university career in the first year of their PhDs, by the third year this number went down to 37. For men, it went from 61 percent to 59 percent by their third year. The story rounds up experimental data from two recent studies that looked into this phenomenon, citing confronting gender bias, the solitary nature of research, and the competition for tenured posts as some of the factors that drove the nearly 1,000 scientists surveyed from the bench.
