A fossil discovery in South Africa suggests that P. robustus evolved rapidly during a turbulent period of local climate change about 2 million years ago, resulting in anatomical changes that previously were attributed to sex. An international research team including anthropologists at Washington University in St. Louis reported their discovery in Nature Ecology & Evolution on Nov. 9.

Research from the lab of Kimberly Parker in the McKelvey School of Engineering at Washington University in St. Louis has discovered the mechanism that keeps formulations of the herbicide dicamba from going airborne. And they consider why it sometimes fails.

Scaled survivors of the coldest night in south Florida’s recent history all converged on the same new, lower limit of thermal tolerance, regardless of their species’ previous ability to withstand cold. Biologist James Stroud in Arts & Sciences at Washington University in St. Louis led the team that reported the findings in the journal Biology Letters.

Four and a half feet — as long as debaters are at least this far apart, with airflow directed back at them, the risk of infection with SARS-CoV-2 is minimal to none, say researchers at Washington University in St. Louis.

Climate change is affecting the spread and severity of infectious diseases around the world — and infectious diseases may in turn be contributing to climate change, according to new research from Washington University’s Living Earth Collaborative working group led by biologist Amanda Koltz in Arts & Sciences.

Michael Wysession, professor in earth and planetary sciences, and Bryn Lutes, a lecturer in chemistry, both in Arts & Sciences at Washington University in St. Louis, believe that high school students will learn chemistry better when they crunch actual climate data, rather than memorize the periodic table by rote. They helped write a national chemistry curriculum that is loaded with real-world examples — like ocean acidification — and is already being rolled out by school districts in Los Angeles and other parts of California.

A new study involving Washington University in St. Louis researchers finds consumers across the United States and in some European countries are ready to start paying for climate action now.

Working together to develop a collaborative and coordinated response to the climate crisis in the Midwestern region is the top goal of the upcoming Midwest Climate Summit, which Washington University in St. Louis developed in close partnership with many leading Midwestern organizations. The event, which is free and open to the public, is presented with support from Bloomberg Philanthropies.

Carlos Botero, assistant professor of biology in Arts & Sciences at Washington University in St. Louis, finds that parasitic birds living in more variable and unpredictable habitats tend to hedge their bets by laying eggs in the nests of a greater variety and number of hosts. The study is published Aug. 21 in Nature Communications.

Writing in my bedroom office under a stay-at-home order, the coronavirus is reminding me and the world of our interconnectedness and our humanity. We as individuals and as communities—local, national and global—are asking ourselves: How are we adjusting to a new normal? How are we understanding each other and our needs, both individually and collectively?
