One gene provides fruit fly both antenna and color vision

The areas stained blue are regions in the fruit fly where the spineless gene is expressed.A team of researchers that includes biologists from Washington University in St. Louis has discovered that a gene involved in the development and function of the fruit fly antenna also gives the organism its color vision. Claude Desplan, Ph.D., professor of biology at New York University, and his students made the discovery and provided the data. Ian Duncan, Washington University professor of biology, and his wife, research assistant Dianne Duncan, provided the Desplan laboratory fruit fly (Drosophila) clones and mutants and technical assistance that helped locate where the gene, called spineless, is expressed in the retina.

Working memory key to breakthroughs in cognitive neuroscience

Unraveling the mysteries of the human brain, and the mind it gives rise to, is within the reach of modern science, suggests a forthcoming issue of the journal Neuroscience. The special issue explores how sophisticated working memory processes — from the firing of a single neuron to the activation of multiple brain regions — help shape our understanding of the world, says issue co-editor Grega Repovs, a visiting post-doctoral fellow at Washington University in St. Louis.

Dangerous glucose-hungry cervical tumors can be detected using PET scans

Cervical cancers that take up a lot of blood sugar, or glucose, are more resistant to treatment than those that are less glucose-hungry, according to research at the School of Medicine. The researchers also found that the high glucose-uptake tumors can be identified with PET scans, which are already routinely used to determine tumor size and lymph node involvement in cervical cancer patients.

Global program to eliminate elephantiasis has early success in Egypt

Organizers of a 20-year global effort to eliminate a parasitic infection that is a leading cause of disability have an early victory to savor: a five-year Egyptian elimination campaign has mostly succeeded, according to a new report in the March 25 issue of The Lancet. Infection with the parasites, threadlike filarial worms, can lead to the dramatic, disfiguring swelling known as elephantiasis.

Procedure cures some diabetic mice, but not in the way previously reported

Researchers attempting to reproduce a controversial 2003 mouse experiment suggestive of a cure for type 1 diabetes have found evidence that the experimental procedure does eliminate diabetic symptoms in a small fraction of the mice exposed to it. However, scientists from the School of Medicine found no signs that the procedure was working in the manner reported by the group of scientists at Harvard University who originated it.

Siteman Cancer Center joins National Comprehensive Cancer Network

Center for Advanced Medicine, home of Siteman Cancer CenterThe Siteman Cancer Center at Barnes-Jewish Hospital and the School of Medicine has been accepted into The National Comprehensive Cancer Network (NCCN), an alliance of the world’s leading cancer centers.
