By Jeff Basara, Associate Professor of Meteorology, University of Oklahoma; and Jordan Christian, Postdoctoral Researcher in Meteorology, University of Oklahoma Flash droughts develop fast, and when they hit at the wrong time, they can devastate a region’s agriculture. They are also becoming increasingly common as the planet warms. In a study published May 25, 2023, we found that the risk of flash droughts, which can develop in the span of a few weeks, is on pace to rise in every major agriculture region around the world in the coming decades. In North America and Europe, cropland that had a...

By Robert Samuels, Continuing Lecturer in Writing, University of California, Santa Barbara The United States is an increasingly polarized country when it comes to politics, but one thing that almost all people want is to live a long and healthy life. More and more Americans are moving from Democratic-leaning blue states to Republican-voting red ones, and one of the effects of this change is that they are relocating to places with lower life expectancy.

I curated my first exhibition of his work in 2007. The most recent show, “Richard Avedon: Relationships,” is now being exhibited in Milan. Avedon’s portraits include...

By Ben Thomas Gleeson, Doctoral Candidate, Australian National University; and Laura A. B. Wilson, ARC Future Fellow, Australian National University In the 19th century, Charles Darwin was one of the first to notice something interesting about domesticated animals: different species often developed similar changes when compared to their ancient wild ancestors. But why would a host of seemingly unrelated features repeatedly occur together in different domesticated animals? Scientists call this collection of shared changes “domestication syndrome,” and the reason it occurs is still hotly debated. In a new paper in Proceedings of the Royal Society B, we argue that...
