The results of a significant study, which was conducted in part by Ruth B. Moore Professor of Biological Anthropology Richard Wrangham, was recently published in a September 18, 2014 issue of Nature. The study collected data from a number of chimpanzee research sites and showed that there is no correlation between violent behavior and human impact in those sites. Authors of the study went on to conclude that violent and lethal behavior in chimpanzees is a natural part of their behavior.

HEB graduate student Eric Castillo's article titled, "Effects of Pole Compliance and Step Frequency on the Biomechanics and Economy of Pole Carrying During Human Walking" was published in the July 2014 issue of the Journal of Applied Physiology. The article explores why humans around the world use carrying poles to transport heavy loads. Experiments suggest that people can save metabolic energy by tuning their gait cadence to the natural vibration frequency of the weighted pole.
