Researchers from the Tyson Research Center at Washington University in St. Louis and St. Louis College of Pharmacy have set up 34 motion-activated cameras to capture images of wildlife in area parks and green spaces. Students and volunteers help identify the species in an effort promote local biodiversity and improve the coexistence of humans and wildlife.

The School of Law at Washington University in St. Louis has launched a new First Amendment Clinic, aimed at allowing students to gain experience by providing legal assistance to organizations, students, journalists and citizens.

A team led by researchers at the School of Medicine in St. Louis has identified a pair of genes that influence risk for Alzheimer’s disease. The genes — known as MS4A4A and TREM2 — affect the brain’s immune cells. They influence Alzheimer’s risk by altering levels of TREM2, a protein that is believed to help microglia cells clear excessive amounts of the Alzheimer’s proteins amyloid and tau from the brain.

When it comes to plant growth and development, one hormone is responsible for it all: auxin. New Washington University in St. Louis research has uncovered a mechanism by which it can affect a plant in a myriad of ways.

Of all the reasons why researchers would prefer more robust monitoring of pollutants in the atmosphere, one stands out: Having this basic information is an indication of progress in the realm of environmental science. A McKelvey School of Engineering scientist outlines the extent of the gap between what researchers know and don’t know.

Researchers at the School of Medicine have found the molecular signature of a healthy gut microbial community – the kind that can keep the intestinal bacteria Clostridium difficile (C. difficile) from overgrowing and causing diarrhea.

When the Washington University in St. Louis Class of 2023 arrives Aug. 17, they will experience a nine-day Bear Beginnings orientation program that is more inclusive, more fun and, yes, more days. Traditions such as Convocation and the Common Reading Program discussion will continue, but Bear Beginnings also will include new programs.

Research from Washington University in St. Louis finds that mutations of a gene implicated in long QT syndrome in humans may trigger seizures because of their direct effects on certain classes of neurons in the brain — independent from what the genetic mutations do to heart function. The new work from Arts & Sciences was conducted with fruit flies and is published August 8 in PLOS Genetics.

Police violence is a leading cause of death for young men in the United States, finds a new study from Washington University in St. Louis. Over the life course, about 1 in every 1,000 black men can expect to be killed by police.

In a new study involving a researcher from Washington University in St. Louis’ Olin Business School, the co-authors discovered something they say surprised them: Medicare Part D’s setup actually inhibits insurers from seeking higher subsidies from the government. It keeps subsidies in check by virtue of the way it’s designed.
