PNAS
Published November 11, 2019
Hurricanes have become more destructive since 1900, and the worst of them are more than three times as frequent now than 100 years ago.

Diversity and Distributions
Published September 26, 2019
As prairie climate patterns change, local climate and climate change will likely influence bird populations more than how the land is used does. Progressively warmer, wetter conditions may benefit some birds, including some at-risk species, with wetland vegetation buffering climate change effects and improving conditions for aquatic insects, a major food source for insect-eating birds.

Medicine & Science in Sports & Exercise
Published October 23, 2019
Contrary to a frequently held belief among some researchers that hormonal fluctuations linked to menstrual cycles can yield inconsistent results in exercise brain research, this study shows exercise-related benefits to brain health and cognition have nothing to do with a woman’s menstrual cycle. This means researchers should not limit women’s participation in this kind of research. Read more>
