Vector-borne diseases shaped human history and reveal race disparities In December 2015, a yellow fever outbreak began in Luanda, Angola. This outbreak was the largest reported in Angola during the last 30-years. In a new study, researchers examine the ways in which vector-borne diseases, like yellow fever, have shaped society and culture.

 E-Mail Today, the average American is unlikely to spend time worrying about malaria. Although the disease is commonly perceived to be restricted to other parts of the world, it played a significant role in shaping American history. It even helped turn the tide of the American Revolutionary War by infecting so many British soldiers that General Cornwallis was forced to surrender at Yorktown. First-year students in a 2019 introductory seminar class led by Erin Mordecai, an assistant professor of biology in the School of Humanities and Sciences (H&S), delved into this and other historical exam...

Unusual DNA folding increases the rates of mutations DNA sequences that can fold into shapes other than the classic double helix tend to have higher mutation rates than other regions in the human genome. New research by a team of Penn State scientists shows that the elevated mutation rate in these sequences plays a major role in determining regional variation in mutation rates across the genome.  Deciphering the patterns and causes of regional variation in mutation rates is important both for understanding evolution and for predicting sites of new mutations that could lead to disease. “Mos...
