science news 4.4.2019

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.

These newly discovered geological formations feature upside down 'mirror-like flanges' that act as pooling sites for discharged fluids."
