Washington University in St. Louis researchers have developed a test that quickly detects the presence of Zika virus in blood.

What is the nature of the self? How do conceptions differ in Western and non-Western cultures? Can individual and collective traumas ever be “fixed,” or do certain wounds defy the notion of repair? In “Reason’s Oxymorons,” French-Algerian artist Kader Attia surveys how different cultures, societies and disciplines grapple with questions of loss and damage.

A new study from the School of Medicineshows that mutations in the gene TREM2 cause an energy shortage in the brain’s immune cells, leading to their failure to protect neurons from damaging clumps of protein.

Results of a small clinical trial show promise for treating a rare neurodegenerative condition that typically kills those afflicted before they reach age 20. The disease, called Niemann-Pick type C (NPC), causes cholesterol to build up in neurons, leading to a gradual loss of brain function.

There has been discussion and discourse in recent days — in Missouri and across the country — about a travel advisory issued by the NAACP. Chancellor Wrighton offers his perspective as the university prepares to welcome new and returning students to campus for the start of the 2017-18 academic year.

William F. Tate, dean of the Graduate School at Washington University in St. Louis, has received the 2017 Inspiring Leaders in STEM Award from INSIGHT Into Diversity magazine. Tate is also vice provost for graduate education and the Edward Mallinckrodt Distinguished University Professor in Arts & Sciences. 

The combination of a bacterium that normally lives in the gut and a protein-rich diet promotes a more tolerant, less inflammatory gut immune system, according to new research at the School of Medicine. The findings may potentially spell relief for people living with inflammatory bowel disease.

A new study from the School of Medicine shows that a particular gut microbe can prevent severe flu infections in mice, likely by breaking down naturally occurring compounds — called flavonoids — commonly found in foods such as black tea, red wine and blueberries.

The 21st Century Cures Act and key changes made during its drafting remain controversial and show the need for a more informed comment period for future health care legislation, says an expert on health law at Washington University in St. Louis.

Sophisticated techniques for testing hypotheses about the brain by activating and silencing genes are currently available for only a handful of model organisms. Scientists at Washington University in St. Louis are working on a simplified toolkit that will allow scientists who study animal behavior to manipulate the genomes of many other animals with the hope of accelerating progress in our understanding of the brain.
