Switching tracks: Understanding photosynthesis

Switching tracks: Understanding photosynthesis

Chemists in Arts & Sciences have re-engineered one of nature’s solar cells to drive electrons down an alternate path. This work advances the understanding of the earliest light-driven events of photosynthesis and is published in the Proceedings of the National Academy of Sciences.
Chimpanzees more likely to share tools, teach skills when task is complex

Chimpanzees more likely to share tools, teach skills when task is complex

New Arts & Sciences research finds that chimpanzees that use a multi-step process and complex tools to gather termites are more likely to share tools with novices. The study helps illuminate chimpanzees’ capacity for prosocial — or helping — behavior, a quality that has been recognized for its potential role in the evolution of human cultural abilities.
‘Lost crops’ could have fed as many as maize

‘Lost crops’ could have fed as many as maize

For thousands of years, goosefoot and knotweed were grown as crops, possibly feeding as many indigenous people of North America as corn. But the domesticated forms of these lost crops became lost over the years, and now a Washington University in St. Louis archaeologist is trying to figure out why — and recreate them.
And then there was light

And then there was light

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.
Survey: Electorate wants candidates, parties to act on climate change

Survey: Electorate wants candidates, parties to act on climate change

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.
Division of Computational and Data Sciences marries AI, social science

Division of Computational and Data Sciences marries AI, social science

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.
