In a recent study, a team of scientists led by researchers from the Physics Laboratory of ENS de Lyon (CNRS/ENS de Lyon) focused on the flow-induced responses of colloidal dispersions. Their work provides a better understanding of how colloids structure themselves under the effect of shear, an important step towards understanding this essential process in many industrial applications.

Publication of the IGFL in the journal PNAS on March 19, 2024. News by CNRS Biology on April 12, 2024. During embryonic development, motor neurons, located in the spinal cord, emit extensions - the axons - which must find their way to their targets - the muscle cells. These motoneurons, last link between electrical and mechanical signals in the locomotor system, trigger movement via their axons.

An international consortium of paleontologists, geologists and biologists describes the discovery of fossil assemblages spanning the last 130,000 years beneath the Ariane 6 rocket launch site in Kourou, French Guiana. The consortium, coordinated by scientists from the Montpellier Institute of Evolutionary Sciences (Université de Montpellier/CNRS/IRD) and the Université de Guyane/Géosciences Montpellier, includes Frédéric Quillévéré from the Laboratoire de Géologie de Lyon : Terre, Planètrs, Environnement (LGL-TPE, CNRS/Université Lyon 1/ENS de Lyon/Université Jean Monnet).

Work by a consortium of scientists, including a team from the Centre International de Recherche en Infectiologie (CIRI, CNRS/Inserm/ENS de Lyon/Université Lyon 1), describes viruses as modulators of human cell functions. The interaction interfaces of viral proteins with human proteins are used as matrices to design original chemical molecules, offering new perspectives in multiple therapeutic areas.

The scientific community has been sounding the alarm over the effects of pesticide use on human health and the disappearance of numerous species in agricultural environments for half a century. As early as 1962, Rachel Carson's pioneering work predicted "silent springs" caused by the decline of birds, the collateral victims of pesticides via the poisoning of environments and the disappearance of insects.

A new fossil deposit has been unearthed in the Hérault region thanks to the long-term work of a couple of amateur paleontology enthusiasts, whose discoveries have been studied by an international team involving scientists from the CNRS (1) and the University of Lausanne. With over 400 fossils dating back 470 million years, the Cabrières site near Pézenas bears witness to the closest environment ever observed to the South Pole at that time.

Publication involving a former ENS de Lyon PhD candidate and the EVS laboratory, in the journal Marine Geology . Earliest Evidence of Port-Related lead pollution in Bronze Age Greece First discovery of brown coal in a stratigraphic context at the end of the Bronze Age Lechaion's harbour archaeological chronology pushed back by at least 5 centuries New perspectives on regional economy and trade during the LBA/EIA transition Lechaion in Corinth, Greece, is the largest ancient port in Greece.

Publication of the Physics Laboratory and Chemistry Laboratory in the journal Langmuir on November 16, 2023. News by CNRS Chemistry on December 19, 2023. Water flowing over soluble rocks can create patterns of multiple troughs bordered by sharp ridges. By combining field measurements, a numerical model and laboratory experiments, a team led by the MSC laboratory (CNRS/Université Paris Cité), in collaboration with the LPG (CNRS/Nantes Université/Université d'Angers) and the RDP (CNRS/ENS de Lyon/Inrae) has shown that the appearance of these shapes results from a geometric mechanism.

Publication of the Chemistry Laboratory in the journal ACS Catalysis on November 9, 2023. Communication of CNRS Chemistry on November 27, 2023. Producing dihydrogen by electrolysis of water requires rare and therefore expensive catalysts. They could be replaced by another molybdenum-based catalyst, much more abundant but currently less efficient.
