This is the fossil of Saurichthys, a top predator among the Triassic fishes. Credit: Picture: UZH Some 252 million years ago the largest extinction event occurred at the end of the Permian age. It wiped out almost 90 percent of all life in water. So far researchers had assumed that the ecosystems gradually recovered from

A new study published today in the journal Science Advances identifies genetic changes that are linked to dogs’ human-directed social behaviors and suggests

University of Exeter scientists found grey squirrels quickly remembered how to solve a problem they had not seen for almost two years. The squirrels also quickly worked out

The fibres, which resemble miniature bungee cords as they can absorb large amounts

JCU’s Professor Eric Wolanski said even in very warm years with

But now a research team reports that contrary to this belief, chimp muscles’

Since its launch in November 2013 and its orbit insertion in September 2014, MAVEN has been
