Dr. Janet Iwasa presents at the Center for Cellular Dynamics' "Art of Cellular Biology" event

Innovative meeting brings scientists and artists together

The University of Utah’s Dr. Janet Iwasa headlined the “Art of Cellular Biology” event.

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. The modification (indicated by arrow) is essential for initiation of ribonucleotide reduction. This metal-free enzyme could allow microbes associated with strep throat and pneumonia infections to more effectively proliferate during iron/manganese limitation imposed by the human immune system.

Plant virus alters competition between aphid species

In the world of plant-feeding insects, who shows up first to the party determines the overall success of the gathering; yet viruses can disrupt these intricate relationships, according to researchers at Penn State.

Oral microbiota of two-year-old children is related to rapid infant weight gain, a strong risk factor for childhood obesity.

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.

New technology improves CRISPR-Cas9 gene editing in mosquitoes, other species

Using a newly developed method to deliver gene-editing material to the ovary of an adult mosquito, researchers disabled a gene that caused its offspring on the right to be born with white, rather than dark, eyes.
