Researchers led by Kenneth M. Olsen in Arts & Sciences used a new imaging technique to reveal a takeover strategy that has worked for weedy rice over and over again: roots that minimize below-ground contact with other plants.

Researchers in Arts & Sciences have discovered and characterized a new form of oxygen dubbed “featherweight oxygen” — the lightest-ever version of the familiar chemical element oxygen, with only three neutrons to its eight protons.

An interdisciplinary team of researchers from the McKelvey School of Engineering and the School of Medicine have found the most efficient length for cilia, the tiny hair-like structures designed to sweep out the body’s fluids, cells and microbes to stay healthy.

Pregnant women who use cannabis may slightly increase the risk their unborn child will develop psychosis later in life, suggests new research from Washington University in St. Louis.

David Peters, the McDonnell Douglas Professor of Engineering in the McKelvey School of Engineering at Washington University in St. Louis, has a body of work in applied aerodynamics and a host of academic honors, but he’s also a baseball fan. That’s why watching a baseball game takes on a whole new spin, aerodynamically speaking.

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.

A researcher at Washington University in St. Louis travels the Americas, collecting feces from nonhuman primates to determine the risk of Zika reservoirs.

The consortium will address the region’s need for qualified cybersecurity professionals in this fast-growing field and address the growing global threat of cybercrime, which is expected to cost the world $6 trillion a year by 2021.

A biomedical engineer at Washington University in St. Louis is developing a therapeutic option that would prevent opiates from crossing the blood-brain barrier, preventing the high abusers seek.

The movement to abolish clock-time changes each spring and fall is growing — and so is the scientific evidence. Experts say perennial standard time, or “wintertime,” is the best and safest option for public health.
