Even dinosaurs, it appears, were divided by gender. A new study provides the first solid evidence that male and female DINOSAURS looked different from each other. Evan Saitta ’14, who conducted the research for his senior thesis, found that the back plate of the Stegosaurus came in two varieties — females had one type and males the other. Saitta is a graduate student at the University of Bristol in England. The findings were published in PLOS ONE in April.
With the global population rising, policymakers have targeted Africa’s vast wet savannas as a place to produce STAPLE FOODS at low cost to the environment. But a report in Nature Climate Change found that converting Africa’s savannas into farmland would come at a high environmental cost and, in some cases, fail to meet existing standards for renewable fuels. Princeton research scholars Lyndon Estes and Tim Searchinger were the lead authors of the report, published in March.
