A UNIGE study reveals how mechanics, linked to tissue growth, help generate the diversity of biological structures. How can we explain the morphological diversity of living organisms? Although genetics is the answer that typically springs to mind, it is not the only explanation. By combining observations of embryonic development, advanced microscopy, and cutting-edge computer modelling, a multi-disciplinary team from the University of Geneva demonstrate that the crocodile head scales emerge from the mechanics of growing tissues, rather than molecular genetics.

Isoprene From Rainforests Drives New Particle Formation
Changes in atmospheric particles since preindustrial times have masked some of the warming caused by rising levels of carbon dioxide. Atmospheric particles cool the climate by directly reflecting sunlight and by making clouds more reflective; they are also deadly pollution. Fifteen years ago, it was thought that sulfuric acid drove almost all particle formation.
