science news 21.5.2019

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.

How Earth's mantle is like a Jackson Pollock painting
"To geologists, the mantle is so much more than that. It's a region that lives somewhere between the cold of the crust and the bright heat of the core. It's where the ocean floor is born and where tectonic plates die. A new paper published today in Nature Geoscience paints an even more intricate picture of the mantle as a geochemically diverse mosaic, far different than the relatively uniform lavas that eventually reach the surface."

Bonobo mothers help their sons to have more offspring
Intriguing, and a bit scary if extrapolated to humans.


sustainability

Cement as a climate killer: Using industrial waste to produce carbon neutral alternatives
But haven't we been promised that before ?
