Probiotics – living bacteria taken to promote digestive health – evolve once inside the body and have the potential to become less effective and sometimes even harmful, according to a new study from the School of Medicine. The findings suggest that developers of probiotic-based therapeutics must consider how the probiotics might change after administration.

The Brown School’s Center for Social Development is conducting a third wave of research on Child Development Accounts (CDAs) in Oklahoma. Wave 3 of the SEED for Oklahoma Kids experiment expands the original CDA with an automatic progressive deposit and extends the research to examine the accounts’ impacts.

Weight gain during pregnancy and postpartum are important causes of long-term weight gain and the development of obesity-related diseases among women. A new study from Washington University in St. Louis finds providing a home-based lifestyle intervention effectively minimizes excess maternal weight gain during pregnancy and through 12-months postpartum in underserved African American women with obesity.

Although medications to treat opioid use disorder are safe and effective, most people who could benefit from these treatments do not receive them, finds a new report from the National Academies of Sciences, Engineering, and Medicine.

Led by Arpita Bose, assistant professor of biology in Arts & Sciences, a Washington University team showed how an electricity-eating microbe takes up electrons from conductive substances like metal oxides or rust to reduce carbon dioxide. The work is described in the journal Nature Communications.

Mitochondria manufacture energy in every cell of the body, including heart muscle cells. A new study from the School of Medicine shows that cardiac mitochondria are abnormal in the offspring of mouse mothers that become obese due to a high-fat, high sugar diet. Those offspring then pass on the mitochondrial defects at least two more generations.

This fall, one of the top programs for art, architecture and design at a U.S. university — the Sam Fox School of Design & Visual Arts at Washington University in St. Louis — will unveil two major new capital projects that will transform the campus, reshape the visitor experience and firmly establish the prominence of its art museum on campus. The newly constructed Anabeth and John Weil Hall will house state-of-the-art graduate studios, classrooms and digital fabrication spaces. A major expansion and renovation of the Mildred Lane Kemper Art Museum will strengthen visibility, better showcase the renowned permanent collection and accommodate larger and more varied special exhibitions.

Personal experience told Lisa Gorham, captain of the Washington University in St. Louis cross-country, track and indoor track teams, that team sports and adolescent mental health are linked.

Adult depression has long been associated with shrinkage of the hippocampus, a brain region that plays an important role in memory and response to stress.
