It’s a little like finding out that Superman is actually Clark Kent. A team of biologists at Washington University in St. Louis has discovered that two vital cellular components, nuclear RNA Polymerases IV and V (Pol IV and V), found only in plants, are actually specialized forms of RNA Polymerase II, an essential enzyme of all eukaryotic organisms, including humans.

Joshua Maurer, Ph.D., assistant professor of chemistry in Arts & Sciences at Washington University in St. Louis, has received a four-year, $1,216,000 grant from the National Institute of Mental Health for research titled, “Unraveling Development: New Materials for Understanding Neuronal Wiring.” Maurer’s long term objective is to develop methodology that allows the study of a variety of neuronal wiring processes. He is starting by unscrambling a phenomenon known as midline crossing using zebrafish. During development, neurons from the right eye cross the midline of the brain to make a connection in the left hemisphere.

In small towns in the Midwestern United States, people who eat out often at buffets and cafeterias and who perceive their community to be unpleasant for physical activity are more likely to be obese. The findings are published in the December issue of Preventive Medicine.

Six faculty members from Washington University in St. Louis have been named fellows of the American Association for the Advancement of Science (AAAS), the world’s largest general scientific society. The highest honor awarded by AAAS, the rank of fellow is bestowed upon members by their peers in recognition of scientifically or socially distinguished efforts to advance science or its applications.

One of the most pernicious aspects of multiple sclerosis (MS) — its sheer unpredictability — may finally be starting to yield to advanced medical imaging techniques. Researchers from the School of Medicine report online in the journal Neurology that an approach known as magnetic resonance diffusion tensor imaging (DTI) allowed them to estimate three months in advance the chronic effects of inflammation of the optic nerve.

Obesity researchers at the School of Medicine are recruiting families for an on-line program aimed at young children that targets healthy eating and physical activity. The 10-month study will evaluate the effectiveness of Food for Thought, an investigational, Internet-based program for parents of overweight 2- to 6-year-olds.

A program at the School of Medicine and St. Louis Children’s Hospital designed to increase awareness about sickle cell disease and the importance of blood donations within the African-American faith community led to a 60 percent increase in first-time blood donations, a new study has found.

InderTerrie E. Inder, M.D., Ph.D., has received a 2008 Distinguished Clinical Scientist Award from the Doris Duke Charitable Foundation. Inder is a pediatrician and researcher at the School of Medicine and St. Louis Children’s Hospital.

On Dec. 17 at the Duane Reed Gallery in Clayton, the Arts as Healing Program is hosting a public showing of art created by cancer patients. This reception, from 5:30 to 8 p.m., will celebrate these patients as artists and honor “their journey of hope.”
