Slow-motion collisions of tectonic plates under the ocean drag about three times more water down into the deep Earth than previously estimated, according to a first-of-its-kind seismic study that spans the Mariana Trench. The work has important implications for the global water cycle, according to Douglas A. Wiens in Arts & Sciences.

Washington University’s newly launched Cordell Institute for Policy in Medicine & Law has signed on as one of the early signatories of French President Emanuel Macron’s “Paris Call for Trust and Security in Cyberspace,” announced Nov. 12 as part of the peace forum commemorating 100 years since the ending of World War I.

Ovarian cancer claims the lives of more than 14,000 women in the U.S. each year, ranking fifth among cancer deaths in women. A multidisciplinary team at Washington University has found an innovative way to use sound and light to diagnose ovarian tumors, which may lead to a promising new diagnostic imaging technique to improve current standard of care.

A review published in the Nov. 9 issue of Science explores the complexity of evolution’s predictability in extraordinary detail. Jonathan Losos of Arts & Sciences takes on a classic question posed by Stephen Jay Gould in an effort to fully interrogate ideas about contingency’s role in evolution.

David Charbonneau, professor of astronomy at Harvard University, will deliver the annual Robert M. Walker Distinguished Lecture at 7 p.m. Thursday, Nov. 15, in Whitaker Hall, Room 100, on the Danforth Campus of Washington University in St. Louis. The talk, titled “How to Find an Inhabited Exoplanet,” is free and open to the public.

Emotions such as anger, fear, disgust and disillusionment can have dramatically different effects on voter apathy and turnout, said Alan Lambert, associate professor of psychological and brain sciences in Arts & Sciences at Washington University in St. Louis.

Researchers at Washington University in St. Louis take a closer look at lithium metal plating and make some surprising findings that might lead to the next generation of batteries.

Storms help form an important chemical that is highly significant in the search for life on Mars. A team led by Alian Wang of Arts & Sciences created a simulation in the lab that sheds new light on what’s being kicked up by those massive Martian dust devils.

At the river’s edge, where water and soil meet, microbes churn out methane and other greenhouse gasses. Jeffrey G. Catalano, of Arts & Sciences, wades into local Missouri wetlands to determine the role of heavy metals in this process.

Three organizations on two continents are working to figure out if one subspecies of colobus monkey is actually two. The answer could help endangered monkeys and clarify questions about zoo populations.
