A new study in mice co-authored by School of Medicine scientists suggests that Zika infection may have consequences for men that interfere with their ability to have children. Studies in people are needed to determine if men are similarly affected.

If mental illness runs in your family, your genetic makeup may also make you more likely to use drugs and alcohol, suggests new research from Washington University in St. Louis.

Scientists at the School of Medicine have shown that supplementing healthy mice with a natural compound called NMN can compensate for a loss of energy production in aging cells, reducing typical signs of aging such as gradual weight gain, loss of insulin sensitivity and declines in physical activity.

Patients with chronic obstructive pulmonary disease (COPD) often receive portable oxygen therapy to help raise oxygen levels and allow them to breathe easier. But a major study published Oct. 26 in The New England Journal of Medicine indicates that supplemental oxygen does not benefit a large group of patients with COPD: those with moderately low levels of oxygen in the blood.

State actions to regulate retail sales of tobacco nearly doubled between 2012 and 2014, according to new research from the Brown School at Washington University in St. Louis, but much of the activity was directed at e-cigarettes, perhaps the least harmful tobacco product.

Using MRIs, researchers at the School of Medicine have identified areas in the brains of children with Tourette’s syndrome that appear markedly different from the same areas in the brains of children who don’t have the neuropsychiatric disorder. The findings were published online Oct. 25 in the journal Molecular Psychiatry.

Scientists at Washington University School of Medicine in St. Louis and Stanford University report that they have designed small compounds that have the potential to correct the mitochondrial dysfunction that leads to Charcot-Marie-Tooth and other conditions involving mitochondria.

Scientists have linked mutations in a single gene to autism in people who have a rare tumor syndrome typically diagnosed in childhood. The findings, in patients with neurofibromatosis type 1 (NF1), may lead to a better understanding of the genetic roots of autism in the wider population.

As part of the White House BRAIN Initiative, researchers at Washington University School of Medicine in St. Louis have received two grants to develop tools to map and activate pathways in the brain using light.

Washington University School of Medicine in St. Louis has received a two-year, $8 million grant from the Bill & Melinda Gates Foundation to evaluate an investigational treatment regimen for lymphatic filariasis, a neglected tropical disease.
