When it comes to communication in the brain, more is usually better. But now scientists, including Maurizio Corbetta, MD, have linked increased communication in a network of brain regions to more severe mental impairment in patients with early-stage multiple sclerosis (MS).

A new study shows that annual prostate cancer screening does not reduce deaths from the disease, even among men in their 50s and 60s and those with underlying health conditions. The study was published online Jan. 6 in the Journal of the National Cancer Institute.

Providing clues to deafness, researchers at Washington University School of Medicine in St. Louis have identified a gene that is required for proper development of the mouse inner ear. In humans, this gene, known as FGF20, is located in a portion of the genome that has been associated with inherited deafness in otherwise healthy families.

Some WUSTL news stories never get old, and some just get better with time. WUSTL news editors picked 11 stories from 2011 — some new, some old — but all worth a second look as we head into 2012.

Jordan Teisher, a doctoral student in evolution, ecology and population biology, and Jeremy King, a doctoral student in plant biology, have been named the first Monsanto graduate fellows at Washington University.

The School of Medicine will present its annual Martin Luther King Jr. Celebration Lecture at 4 p.m. Monday, Jan. 16, in the Eric P. Newman Education Center.

High levels of tau protein in fluid bathing the brain are linked to poor recovery after head trauma, according to a study from Washington University School of Medicine in St. Louis and the Fondazione IRCCS Ca Granda-Ospedale Maggiore Policlinico in Milan, Italy. The results were reported online Nov. 23 in the journal Brain.

Scientists have uncovered a critical genetic mutation in some patients with myelodysplastic syndromes — a group of blood cancers that can progress to a fatal form of leukemia. The research team at Washington University School of Medicine in St. Louis also found evidence that patients with the mutation are more likely to develop acute leukemia.

Jennifer K. Lodge, PhD, and Ernst Zinner, PhD, have been named fellows of the American Association for the Advancement of Science (AAAS), the world’s largest general scientific society. Lodge and Zinner are among 539 new fellows who will be acknowledged in the Dec. 23 issue of Science magazine.The 2011 AAAS Fellows also will be honored at a Feb. 18, 2012, ceremony at the organization’s annual meeting in Vancouver, Canada.

First-year medical students at Washington University School of Medicine have much to learn about the structure of the body and its cells. Soon, they will have new inspiration for that learning journey in the form of a series of detailed black-and-white electron micrographs of cells and their interiors created by John Heuser, MD, professor of cell biology and physiology.
