Dental sensitivity is unique in that it is mediated by cells called odontoblasts, located in the dental pulp at the center of the tooth. According to hydrodynamic theory, the activation of odontoblastic processes is linked to the movement of fluids in the dentinal porosity induced by external stimuli. A new study conducted at the Interdisciplinary Laboratory of Physics (LIPhy - CNRS/UGA) shows that this porosity has all the characteristics of a complex network. Far from functioning as independent sensors, odontoblasts could therefore, in theory, adopt collective behaviors that are very different from the simple sum of individual responses.

When light is scattered, how accurately can a measurement result be derived from that light? An international research team has explored the limits of what is possible using artificial intelligence.

A scientific team from Grenoble, involving the Laboratoire interdisciplinaire de physique (LIPhy - CNRS/UGA) and the Centre Inria de l'UGA, has developed a groundbreaking computational model that reveals universal laws governing how creatures swim across vastly different sizes and environments — from microscopic bacteria to massive blue whales.
