Many studies have linked more sleep to better memory, but new research in fruit flies at Washington University School of Medicine in St. Louis demonstrates that extra sleep helps the brain overcome catastrophic neurological defects that otherwise would block memory formation.

An enzyme secreted by the body’s fat tissue controls energy levels in the brain, according to new research led by Shin-ichiro Imai, MD, PhD, of the School of Medicine. The findings, in mice, underscore a role for the body’s fat tissue in controlling the brain’s response to food scarcity, and suggest there is an optimal amount of body fat for maximizing health and longevity.

U.S. Sen. Roy Blunt, R-Mo., visited the Medical Campus this week to meet with physicians who treat patients with Alzheimer’s disease, and patients and caregivers who live with the debilitating disease every day. Blunt, pictured with physician-scientist Randall J. Bateman, chairs a subcommittee that oversees funding for medical research.

While in Ethiopia as a Fulbright scholar, L. Lewis Wall, MD, DPhil, met a woman who is trying to change the experience of adolescent girls in rural Ethiopia by providing them with reusable sanitary pads and education about menstruation. Wall and his wife, Helen, decided they had to do something to support the mission.

Scientists have long suspected that respiratory viruses play a critical role in the development of chronic lung diseases such as asthma and chronic obstructive pulmonary disease (COPD). Studying mouse and cell models of this process, researchers now have shown how immune cells dispatched to the lung to destroy a respiratory virus can fail to disperse after their job is done, setting off a chain of inflammatory events that leads to long-term lung problems.

Scientists, including researchers from Washington University School of Medicine, have found antibiotic resistance genes in the bacterial flora of a South American tribe that never before had been exposed to antibiotic drugs. The findings suggest that bacteria in the human body have had the ability to resist antibiotics since long before such drugs were ever used to treat disease.

Timothy M. Miller, MD, PhD, a leading researcher in the neurodegenerative disorder amyotrophic lateral sclerosis (ALS), has been named the David Clayson Professor of Neurology at the School of Medicine. The professorship was established in 2001 through a bequest from David Clayson, PhD, to support innovative research into treatments for ALS.

Transit stops close to home and workplace incentives are associated with higher likelihood that commuters will choose public transportation, according to research from the Brown School at Washington University in St. Louis and Washington University School of Medicine in St. Louis. The study is co-authored by Aaron Hipp, PhD, assistant professor at the Brown School.

John W. Olney, MD, the John P. Feighner Professor of Psychiatry and professor of pathology and immunology, died Tuesday, April 14, 2015 at his home in St. Louis after a battle with lung cancer and amyotrophic lateral sclerosis (ALS). He was 83.

Smokers with a specific genetic variation are more likely to keep smoking longer than those who don’t have the gene variant. They’re also more likely to be diagnosed with lung cancer at a younger age, according to new research from Laura Jean Bierut, MD (left), and Li-Shiun Chen, MD, at Washington University School of Medicine in St. Louis.
