Researchers from Washington University in St. Louis and the Chinese Academy of Agricultural Sciences discovered that rice domestication relied on selection for traits determined by a poorly understood portion of the rice genome.

Winter is dark. It’s exhausting. It also features the flu, colds and a tendency to stay indoors. So is Jan. 1 really a good time for resolutions? WashU’s Tim Bono has a better idea: Wait a few months.

New research from Washington University in St. Louis provides insight into how proteins called phytochromes sense light and contribute to how plants grow. Biologists used sophisticated techniques to structurally define the sequence of events that support the transition between light- and dark-adapted states.

In a November wave of The American Social Survey conducted by the Weidenbaum Center on the Economy, Government, and Public Policy, political scientists polled likely primary voters to find that — despite consensus among Democratic candidates and the Trump administration’s actions to repeal environmental regulations — the two parties’ electorates don’t match their candidates’ stances on climate change.

A team of Washington University in St. Louis scientists at McMurdo Station, Antarctica, successfully launched its SuperTIGER (Super Trans-Iron Galactic Element Recorder) instrument, which is used to study the origin of cosmic rays. 

The interdisciplinary Division of Computational and Data Sciences, one of a few of its kind in the country, focuses on turning the computational lens on social sciences. In the new PhD program, students have two advisers, one in computer engineering and one in a social science domain from social work and public health, political science, or psychological and brain sciences.

Jhan Salazar, a graduate student in biology in Arts & Sciences, was recognized by the Colombian organization Color de Colombia as the “Afro-Colombian of the Year” in the youth category in a nationally televised ceremony in Colombia on Dec. 2.

Researchers from Washington University in St. Louis will develop and deploy a new telescope designed to measure the linear polarization of X-rays arriving from distant neutron stars, black holes and other exotic celestial objects. The instrument will be flown on a minimum of two scientific balloon launches as early as summer 2021. The NASA-funded effort builds on promising results from a previous balloon-borne mission known as X-Calibur and is dubbed XL-Calibur.

Harsh Moolani initially shrugged off a friend’s advice to quit trying to do it all. Then he considered the source: a remarkable woman with a successful career, good friends — and only a few months to live. Moolani is set to graduate in December with a degree in neuroscience in Arts & Sciences. He will remain in St. Louis and expand Create Circles, the nonprofit he founded to connect older and younger adults.

In a Dec. 10 briefing on Capitol Hill, chemist Sophia Hayes of Washington University in St. Louis and an expert on helium testified that steep price increases and “supply shocks” threaten basic research in academic settings. Shortages will also lead to broader health and industry applications, she said.
