Subduction zone geometry: a mega-earthquake risk indicator
Subduction zone geometry: a mega-earthquake risk indicator
Mega-earthquakes (with a magnitude greater than 8.5) mainly occur on subduction faults where one tectonic plate passes under another. But the probability of such earthquakes does not appear to be even across these zones. In a study published on 25 November 2016 in the journal Science , researchers from the University of Oregon and Géoazur laboratory (CNRS/Université Nice Sophia Antipolis/Observatoire de la Côte d'Azur/IRD) show that mega-earthquakes mostly occur on the flattest subduction zones.

How organ regularity emerges from cell randomness
How organ regularity emerges from cell randomness
An international team (Cornell University, Hokkaido University, Max Planck Institute, Ecole normale supérieure de Lyon / Université Claude Bernard Lyon 1 / CNRS / INRA) unravels how random cell growth contributes to making organs reach the correct size and shape. This study was published in What makes an elephant look like an elephant, or a mouse look like a mouse? How do our two arms reach less than 1% dissimilarity in length? Despite continuous progress in developmental biology, we still do not know the answers to such deceptively simple questions.

Ocean pollution: focusing on the fragmentation of plastic waste
Ocean pollution: focusing on the fragmentation of plastic waste
First discovered by sailors, the masses of plastic debris floating at the center of vast ocean vortices called gyres are today under close scrutiny by scientists. To better understand the fragmentation of microplastics under the effect of light and abrasion by waves, researchers combined physico-chemical analyses with statistical modeling.
