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

Shake, Rattle, and Roll to High Efficiency Photovoltaics
Using ultrafast infrared imaging techniques (bottom left), a team of researchers from Penn State has revealed that the remarkable electronic properties of halide perovskite photovoltaic materials properties arise from large-scale motion of atoms (bottom right) in their crystalline lattice (top).

A naturally occurring antibiotic active against drug-resistant tuberculosis
The natural antibiotic kanglemycin A binds bacterial RNA polymerase at the rifampicin binding-pocket, but maintains potency against rifampicin-resistant mutants due to two unique chemical groups (digitoxose and succinic acid) that increase its affinity to rifampicin-resistant RNA polymerase by binding just outside the rifampicin-binding pocket.

Young children’s oral bacteria may predict obesity
The composition of oral microbiota -- the collection of microorganisms, including beneficial bacteria, residing in the mouth -- in two-year-old children may predict their weight gain, according to a new study of over 226 children and their mothers. Credit: Penn State (Click to enlarge)
