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.

Discovery of chemical clue may lead to solving cacao's black pod rot mystery
The finding of relatively high levels of the antimicrobial compound clovamide in the leaves of a disease-resistant strain of cacao has significant implications for breeding trees that can tolerate black pod rot, according to Penn State researchers who conducted a novel study.

Warbler coloration shaped by evolution via distinct paths
Two genes that are important for the diverse colors and patterns of warbler plumage have evolved through two very different processes, according to a new study led by Penn State researchers. These evolutionary processes could help explain the rapid evolution of these songbirds into so many unique species.
