Toute l'actus du CNRS
  1. Jacket for cardiorespiratory monitoring of laboratory animals
    To meet their objective of offering connected devices for the physiological monitoring of laboratory animals without recourse to anesthesia or surgery, researchers from the TIMC-IMAG laboratory (CNRS / Université Grenoble Alpes / Grenoble INP / VetAgro Sup) have developed a jacket that measures rodent cardiac and respiratory activity. This patented tool soon to be released by Etisense, a TIMC-IMAG spin-off company, paves the way for enhancing the quality of research data and advancing animal welfare.
  2. Alzheimer's disease: how amyloid aggregates alter neuronal function
    The accumulation of amyloid peptides in the form of plaques in the brain is one of the primary indicators of Alzheimer's disease. While the harmful effects of amyloid peptide aggregates are well established, the mechanism through which they act on brain cells remains ill-defined. Researchers from CNRS and université de Bordeaux have just revealed that they alter the usual functioning of connections between neurons by interacting with a key enzyme of synaptic plasticity. The results will be published on June 12, 2018 in the journal Cell Reports.
  3. Pandoravirus: giant viruses invent their own genes
    Three new members have been isolated and added to the Pandoravirus family by researchers at the Structural and Genomic Information Laboratory (CNRS/Aix‐Marseille Université), working with partners at the Large Scale Biology Laboratory (CEA/Inserm/Université Grenoble‐Alpes) and at CEA-Genoscope. This strange family of viruses, with their giant genomes and many genes with no known equivalents, surprised the scientists when they were discovered a few years ago. In the 11 June 2018 edition of Nature Communications, researchers offer an explanation: pandoviruses appear to be factories for new genes – and therefore new functions. From freaks of nature to evolutionary innovators, giant viruses continue to shake branches on the tree of life!
  4. Bees and the thought of naught
    Honeybees can conceive and interpret zero. This has just been demonstrated by a scientist from the Research Centre on Animal Cognition (CNRS / Université Toulouse III—Paul Sabatier) and her Australian colleagues, proving for the first time ever that insects are capable of mathematical abstraction. As zero, designating nothingness, neutrality, or absence, is a relatively recent concept for humans, these findings—published in Science (June 8, 2018)—raise questions about its symbolic significance in the history of mathematics.
  5. The search for the origin of mast cells
    A team of researchers from CNRS, INSERM and Aix-Marseille Université (AMU) at the Centre of immunology (Marseille-Luminy (CIML), together with the Singapore Immunology Network (SIgN)1, has proven that not all of the immune system's important mast cells are produced in bone marrow, as was previously thought. Scientists found embryonic mast cells in mice with functions that are likely to be different than the mast cells found in adults. The study appears in the June 2018 edition of Immunity.
