In the 1980s, geochemical observations led researchers to propose a geodynamic model of the mantle's marbled structure. A team of scientists, some of whom are attached to the Laboratory of Geology of Lyon: Earth, Planets, Environment (LGL-TPE, CNRS/ENS de Lyon/Claude Bernard Lyon 1 University), has been working on this model using a seismological perspective.

A team from the Institut Pasteur, hosted at CIRI, has developed and successfully tested on a primate model a pentavalent vaccine against the five pathogenic arenaviruses circulating in South America.

By coupling a tensile machine and an in situ dielectric measurement, physicists from Lyon (ENS de Lyon Physicis Laboratory and MATEIS) have made a breakthrough in understanding the molecular reorganizations that allow a polymer film to stretch. The results of this study are published in the journal Macromolecules .

The stage at which memory CD8 T cells diverge after a viral infection remains debated. These cells are essential for effective protection of individuals during subsequent infection.

Publication of the CIRI in the journal PNAS . CNRS-INSB communication on September 7, 2022. The coronavirus disease 19 (COVID-19) pandemic is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), a coronavirus that spilled over from the bat reservoir. Despite numerous clinical trials and vaccines, the burden remains immense, and the host determinants of SARS-CoV-2 susceptibility and COVID-19 severity remain largely unknown.

Publication of the IGFL in the journal PNAS . CNRS-INSB communication on July 12, 2022. Some organisms have the fascinating capacity to regenerate lost body parts. To which extent regeneration entails the redeployment of an embryonic developmental program is a long-standing question of regenerative studies, with implications for development, evolution, and regenerative medicine.

Publication of the RDP in the journal PNAS on May 24, 2022. CNRS-INSB communication on May 30, 2022. Pollen viability depends on a tough external barrier called the pollen wall. Pollen wall components are produced by tapetum cells, which surround developing pollen grains within the anther. Precise coordination of tapetum activity with pollen grain development is required to ensure effective pollen wall formation.

Publication of the IGFL in the journal Animal genetics on March 14, 2022. CNRS-INEE communication on May 3, 2022. We investigated the controversial origin of domestic sheep ( Ovis aries ) using large samples of contemporary and ancient domestic individuals and their closest wild relatives: the Asiatic mouflon ( Ovis gmelini ), the urial ( Ovis vignei ) and the argali ( Ovis ammon ).

Publication of the CIRI in the journal Science Translational Medicine on February 1 st , 2022. Claude Bernard Lyon 1 University focus on February 24, 2022. Transplant recipients, who receive therapeutic immunosuppression to prevent graft rejection, are characterized by high coronavirus disease 2019 (COVID-19)-related mortality and defective response to vaccines.

Publication of the LBMC in the journal Current biology on February 7, 2022. CNRS-INSB communication on February 21, 2022. Wolbachia are widespread endosymbiotic bacteria that manipulate the reproduction of arthropods through a diversity of cellular mechanisms. In cytoplasmic incompatibility (CI), a sterility syndrome originally discovered in the mosquito Culex pipiens , uninfected eggs fertilized by sperm from infected males are selectively killed during embryo development following the abortive segregation of paternal chromosomes in the zygote.

Publication of the CRAL in the journal Astronomy & Astrophysics on Fabruary 8, 2022. CNRS-INSU communication on February 14, 2022. Context . Extreme adaptive optics systems, such as the Spectro-Polarimetric High-contrast Exoplanet REsearch facility (SPHERE), push forward the limits in high contrast and high resolution in direct imaging.

In a new study published in Geophysical Research Letters, two scientists - Chloé Michaut from Ecole normale supérieure de Lyon 1 and Jerome A. Neufeld from University of Cambridge 2 , propose a new model of crystallization of the lunar magma ocean where the crystals remain suspended in the lunar interior and the formation of the crust only begins once a critical crystal content is reached.

CRAL publication in MNRAS , on September 16, 2021. CNRS press release on September 16, 2021. Galaxies can receive and exchange matter with their external environment thanks to the galactic winds created by stellar explosions. Thanks to the MUSE instrument  from the Very Large Telescope at the ESO, an international research team, led on the French side by the CNRS and l'Université Claude Bernard Lyon 1 , has mapped a galactic wind for the first time.

Publication of LGL-TPE in Science on October 7, 2021. CNRS press release on October 7, 2021. The Perseverance rover has now confirmed the suitability of its landing site: Jezero crater really did contain a lake, into which a river flowed through a delta 3.6 billion years ago. Led by a CNRS researcher, the international team involved scientists in France from Université Claude Bernard Lyon 1 and Université Toulouse III - Paul Sabatier , and published its findings on October 7 in Science.

Communication from CNRS on May 18, 2021. Publication of LGL-TPE in the June 2021 issue of Earth-Science Reviews. Fossils of land animals from South America have been found in the Antilles. The appearance/disappearance of archipelagos is due to tectonic plate movements and glacial-interglacial cycles.

Publication of LGL-TPE in the journal Solid Earth on July 21, 2021. Due to the low to moderate seismicity of the European Western Alps, few focal mechanisms are available in this region to this day, and the corresponding current seismic stress and strain fields remain partly elusive. The development of dense seismic networks in past decades now provides a substantial number of seismic records in the 0-5 magnitude range.

Publication of CRMN in the journal PNAS on January 5, 2021. Neurodegenerative disorders are frequently associated with -sheet-rich amyloid deposits. Amyloid-forming proteins can aggregate under different structural conformations known as strains, which can exhibit a prion-like behavior and distinct pathophenotypes.

Study by the LGL-TPE published Geoscience on November 4, 2021. The abrupt changes in mineralogical properties across the Earth's mantle transition zone substantially impact convection and thermochemical fluxes between the upper and lower mantle. While the 410-km discontinuity at the top of the mantle transition zone is detected with all types of seismic waves, the 660-km boundary is mostly invisible to underside P-wave reflections (P660P).

Feedback-driven winds from star formation or active galactic nuclei might be a relevant channel for the abrupt quenching of star formation in massive galaxies.

A team of interdisciplinary researchers has demonstrated that convex optimization is an effective mathematical and numerical tool for a daily estimate of the evolution of the reproductive number for Covid-19, over time and across regions. Monitoring the spread of the Covid-19 pandemic is one of the major challenges of the global health crisis.
