science news 20.8.2019

Today's selection of science news. Links are normally to press releases on EurekAlert (at the bottom end I may also add a couple of newspaper stories). I include quotes from the summary (using quotation marks) in cases where the title alone doesn't reveal what the story is about. My own thoughts appear without quotation marks, if I have any.

more about the crazy ways birds sleep (including during flight) in my feature on the evolution of sleep which came out yesterday.

New artificial compound eye could improve 3D object tracking



Researchers have created a bio-inspired compound eye that is helping scientists understand how insects sense an object and its trajectory with such speed. The compound eye could also be useful for 3D location systems for robots, self-driving cars and unmanned aerial vehicles.
