Polar auroras are fascinating events that are regularly visible on Earth. Yet do they occur on other planets, such as Mars for example? And if so, how can they be observed? In this report, broadcast in partnership with the French daily Le Monde, scientists tracking these auroras have discovered another phenomenon that had never been described on the Red Planet so far.
How did Australopitecus, Homo habilis and our other ancestors or "cousins" walk? To find out, the biomechanists and computer scientists from the HoBis project are modelling the movements of humans equipped with sensors, as well as baboons, who occasionally walk on their two hind legs.
