What happens to gold nanoparticles in cells?
What happens to gold nanoparticles in cells?
Gold nanoparticles, which are supposed to be stable in biological environments, can be degraded inside cells. This research conducted by teams from the CNRS, l'Université de Paris, Sorbonne Université, and l'Université de Strasbourg will be published in PNAS on December 16 2019, and reveals the ability of cells to metabolize gold, which is nevertheless not essential for their functioning.

Observation of the Resonance Frequencies of a Stable Torus of Fluid
Publication by Laboratoire de physique in Physical Review Letters on August 30, 2019. We report the first quantitative measurements of the resonance frequencies of a torus of fluid confined in a horizontal Hele-Shaw cell. By using the unwetting property of a metal liquid, we are able to generate a stable torus of fluid with an arbitrary aspect ratio.

A model for describing the hydrodynamics of crowds
By studying the movement of runners at the start of marathons, researchers from the Laboratoire de physique (CNRS/ENS de Lyon/UCBL) have just shown that the collective movements of these crowds can be described as liquid flows. Their results, published in Science on January 4, 2019, have enabled them to predict how fluctuations in speed and density are transmitted through massive crowds.
