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.

Cyril Picard, teacher-researcher at LIPhy, was on science journalist Adrien Denèle's Twitch channel @Ylizur to explain how energy can be harvested by mixing fresh and salt water.

Cyanobacteria have an internal biological clock that rhythms their activities on a 24-hour cycle. Thanks to this finely regulated mechanism, these micro-organisms are able to anticipate day/night cycles. A study recently published in Scientific Reports looked at how this clock reacts when the temperature drops below 25°C, an important threshold for their physiology.
