Everyone sweats, but it’s unlikely many people ever consider the social and economic impact of our bodies’ built-in air conditioning system. With summer’s hottest days likely still to come, Michael Heffernan, assistant professor of dermatology at the School of Medicine, helps St. Louis Post-Dispatch writer Jeff Daniels take a closer look at this hot topic.

Glowing firefly light reveals interacting proteins.Radiologists at the School of Medicine have developed a first-of-its-kind noninvasive imaging technique that allows them to watch two proteins interacting in live animals. The technique genetically fuses proteins of interest with carefully cleaved sections of luciferase, the protein fireflies use to create light.

Jan Brunstrom demonstrates martial arts moves with cerebral palsy patient Emma Price.A comprehensive care plan involving sports, physical fitness and strength training is key to helping children with cerebral palsy grow into active adults, according to WUSTL pediatric neurologist Jan Brunstrom. Not only are athletic activities fun for children, but they can also reduce the need for traditional therapy.

A five-year, $2.5 million grant from the National Institute for Occupational Safety and Health may help employers determine which employees are more likely to get carpal tunnel syndrome and other hand, wrist and elbow problems. School of Medicine physician Bradley A. Evanoff is leading the study.

H. pylori bound to stomach tissueScientists working to develop a vaccine for the bacterium Helicobacter pylori, the primary cause of ulcers and a contributor to stomach cancers, have uncovered new intricacies in the way the bacterium sticks to the lining of the human stomach.

Scientists have known for years that eating less tends to make animals live longer, but no one is quite sure why. Several School of Medicine researchers studying the effects of caloric restriction on humans may help provide an answer to that question. This story was written by Tina Hesman and published by the St. Louis Post-Dispatch.

MorrisStress appears to increase the severity of Alzheimer’s disease. That’s just one of more than 40 studies presented by Washington University researchers at the Alzheimer’s Association’s 9th International Conference on Alzheimer’s Disease and Related Disorders July 17-22 in Philadelphia. The University’s Alzheimer’s team is led by John C. Morris, M.D., principal investigator of the Alzheimer’s Disease Research Center.

Researchers discovered activity in a part of the brain called the extrastriate body both when subjects viewed body parts and when they pointed to an object.Although we don’t often think about it, the brain is a very complicated place. Even the simple act of pointing at an object requires an intricate network of brain activity. Scientists traditionally thought this network included a one-way “information highway” between the brain’s visual system and its motor and sensory systems, but research at Washington University School of Medicine in St. Louis now challenges that long-held theory. The study demonstrates that the brain’s visual system is responsible not only for seeing and perceiving objects outside the body, but also is involved when individuals sense and manipulate their own bodies.
