Traffic noise stresses out frogs, but some have adapted
Frogs from ponds near highways show a dampened stress response and altered immune profile when experimentally exposed to noise compared to frogs from quiet ponds. This suggests that frogs from noisy ponds have adapted to reduce the negative effects of traffic noise. Credit: Tracy Langkilde, Penn State

DNA structure impacts rate and accuracy of DNA synthesis
The speed and error rate of DNA Synthesis differs between regions of the genome that form the usual DNA structure (B DNA) and those regions that can form other structures (non-B DNA). Credit: Wilfried Guiblet, Penn State

Hot temperatures can trigger an RNA response in plants
A new study used rice seedlings to demonstrate that the stress of hotter temperatures may trigger a response in a plant’s RNA to manage the change in its environment. Photo Credit: Peter Nguyen
Pathogens may evade immune response with metal-free enzyme required for DNA replication
A metal-free ribonucleotide reductase, an enzyme required for DNA replication, from bacterial pathogens uses a post-translationally modified amino acid (pictured) to initiate an essential DNA biosynthesis reaction. Credit: Gavin Palowitch, Penn State
