A research team led by a CNRS 1 researcher has for the first time accurately determined the age of the cave paintings at Font-de-Gaume (Les Eyzies) in Dordogne (southwestern France), according to work to be published on 9 March 2026 in PNAS.

According to a CNRS communication dated February 19, 2026. Based on a scientific publication in Science Advances , to which the RDP - Plant Reproduction and Development Laboratory contributed: "The actin cytoskeleton is required to maintain plant cell division orientation against cellular geometry."
