Usain Bolt's 200m record has not been beaten for ten years and Florence Griffith Joyner's for more than thirty years. And what about if the secret behind beating records was to use mathematics' Thanks to a mathematical model, Amandine Aftalion, CNRS researcher at the Centre d'analyse et de mathématique sociales (CNRS/EHESS), and Emmanuel Trélat, a Sorbonne Université researcher at the Laboratoire Jacques-Louis Lions (CNRS/Sorbonne Université/ Université de Paris) have proved that the geometry of athletic tracks could be optimised to improve records.
As average temperatures rise every year, it is no longer rare to see plants flower as early as February. Behind this phenomenon is a complex of proteins whose activity is controlled by temperature changes, as has just been demonstrated by researchers from the Cell and Plant Physiology Laboratory (CNRS / CEA / INRAE / Université Grenoble Alpes) and their partners.
Energy-dense food, obesity and compulsive food intake bordering addiction: the scientific literature has been pointing to connections between these for years. Scientists at the CNRS and Université de Paris have just shown for the first time how fatty nutrients act on the brain in the reward circuit. Published in Cell Metabolism on 5 March 2020, these results shed new light on the connection between food and eating disorders.
Until now, archaeozoologists have been unable to reconstruct the earliest stages of domestication: the process of placing wild animals in captivity remained beyond their methodological reach 1 . Using the wild boar as an experimental model, a multidisciplinary team made up of scientists from the CNRS and the French National Museum of Natural History 2 have shown that a life spent in captivity has an identifiable effect on the shape of the calcaneus, a tarsal bone that plays a propulsive role in locomotion.
Scientists at the Laboratoire des Maladies Neurodégénératives (CNRS/CEA/Université Paris-Saclay) and the Neurocentre Magendie (INSERM/Université de Bordeaux) have just shown that a metabolic pathway plays a determining role in Alzheimer's disease's memory problems. This work, published on 3 March 2020 in Cell Metabolism, also shows that supplying a specific amino acid as a nutritional supplement in a mouse model of Alzheimer's restores spatial memory affected early.
A Year of Surprising Science From NASA’s InSight Mars Mission
A new comprehension of Mars is emerging based on the first year of NASA's InSight mission. Results described in a set of six papers published today, five and one in Nature Communications , reveal a living planet that is the scene of earthquakes, dust devils and strange magnetic impulses.

Presentation at ISSCC 2020 Shows Role FD-SOI Can Play in Embedding Qubit Arrays with Classic Electronics to Build Large-Scale Quantum Silicon Processors SAN FRANCISCO - Feb. Leti, an institute of CEA, and CEA-IRIG, a fundamental research institute, have created the world's first quantum integrated circuit that demonstrates the possibility of integrating conventional electronic devices and elements with quantum dots on a CMOS chip.
The Marie Sk?odowska-Curie actions support researchers at all stages of their careers, regardless of age and nationality. Researchers working across all disciplines are eligible for funding. The MSCA also support cooperation between industry and academia and innovative training to enhance employability and career development.
A French-British team directed by the Laboratoire d'océanographie de Villefranche-sur-Mer (CNRS/Sorbonne Université) has just discovered that a little known process regulates the capacity of oceans to sequester carbon dioxide (CO2). It should be noted that photosynthesis performed by phytoplankton on the ocean's surface transforms atmospheric CO2 into organic particles, some of which later sink to its depths.
The terrorist attacks committed in Paris and Saint-Denis (France) on November 13, 2015 have left lasting marks, not only on the survivors and their loved ones, but also on French society as a whole. A vast transdisciplinary research program, the " 13-Novembre " project is codirected by Francis Eustache, neuropsychologist and director of the Inserm Neuropsychology and Imaging of Human Memory laboratory (Inserm/Université de Caen Normandie/École pratique des hautes études/Caen university hospital/Cyceron imaging platform) and Denis Peschanski, historian and CNRS senior scientist.
DNA can transiently adopt structures that are more complex than the double helix. Quadruple helices, or DNA quadruplexes, are an example of this. They are the preferred targets in the treatment of cancers. By studying their roles in neurons, an international collaboration involving a chemist from CNRS 1 has for the first time shown that quadruplexes are markers of neuronal ageing and exert a negative influence of autophagy 2 , a primordial process for neurons because of its protective effect against neurodegenerative diseases.
Using albatrosses fitted with loggers, researchers at the CNRS and La Rochelle Université, in association with the Administration des Terres Australes et Antarctiques Françaises, which manages the natural reserves of the French southern and Antarctic lands, have made a first estimation of the number of non-declared fishing boats operating without an identification system in the Southern Ocean: more than a third of the boats the birds detected in international water were non-declared.
Publication by Laboratoire de Physique in Physical Review Letters on December 23, 2019. Pattern formation, observed experimentally in a radio-frequency plasma in annular geometry, and characterized by azimuthal symmetry breaking of the plasma parameters, is reported. The azimuthal modulation increases with increasing pressure in the range 1-300 Pa.

White lupin is a particularly abstemious crop, requiring very little fertiliser and producing high-protein seeds of great nutritive quality. The plant has just yielded the secrets of its genome thanks to the collaboration of eleven French and foreign laboratories coordinated by Benjamin Péret, a CNRS researcher at the Biochimie et physiologie moléculaire des plantes laboratory (CNRS/Inrae/Université de Montpellier/Montpellier SupAgro).
Researchers from the CNRS, Sorbonne Université, université Paris 1 Panthéon-Sorbonne, the Muséum National d'Histoire Naturelle and the Musée du Quai Branly - Jacques Chirac have shown colours formerly painted on the Pachacamac idol, a 15th century Inca God and oracle. Paired with the first carbon 14 dating of the object, these results published in PLOS ONE on 15 January 2020 shed light on colour practices, and how important they were in the Andes at that time.
The small red planet is losing water more quickly than what theory as well as past observations would suggest. The gradual disappearance of water (H2O) occurs in the upper atmosphere of Mars: sunlight and chemistry disassociate water molecules into hydrogen and oxygen atoms that the weak gravity of Mars cannot prevent from escaping into space.

As early as 4 years old, children associate power and masculinity, even in countries considered to be more egalitarian like Norway. This is what scientists at the Institut des Sciences Cognitives Marc Jeannerod (CNRS/Université Claude Bernard Lyon 1) report, in collaboration with the Universities of Oslo (Norway), Lausanne and Neuchâtel (Switzerland), in a study published on 7 January 2020 in Sex Roles .
