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.

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.
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.
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.
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 .
Axons, the threadlike part of a nerve cell that conducts impulses, are both flexible and strong, which makes them a mystery in the eyes of biologists. Recent studies have shown that under the axonal membrane, rings composed of actin filaments give the structure its flexibility. But those studies had not been able to define the precise architecture of these rings.
Scientists have for the first time shown that it is possible to detect the propagation of seismic waves on the seafloor using submarine telecommunications cables. According to their observations, this existing infrastructure could be used to detect earthquakes, as well as swell and underwater noise. The results are published on December 18, 2019, by researchers from the CNRS, OCA, IRD and Université Côte d'Azur working together in the Géoazur laboratory, in collaboration with the company Fébus Optics and the Centre de Physique des Particules de Marseille (CNRS/Aix-Marseille Université) 1.
ANR IA Chairs: two recipients at ENS de Lyon
The 'AI Chairs' aim to offer researchers substantial resources to build a team and carry out an ambitious project whose visible impact is expected. A multi-year program of 40 Chairs in Artificial Intelligence is one of the measures under this research component, which was presented on November 2018 by the Minister of Higher Education, Research and Innovation and the Secretary of State for Digital Technology.

Gold nanoparticles, which are supposed to be stable in biological environments, can be degraded inside cells. This research conducted by teams from the CNRS, l'Université de Paris, Sorbonne Université, and l'Université de Strasbourg will be published in PNAS on December 16 2019, and reveals the ability of cells to metabolize gold, which is nevertheless not essential for their functioning.
Plant Advanced Technologies - PAT announces the allocation of exceptional funding of ¤ 660,000 by the office of Prime Minister Édouard Philippe, as part of the national innovation contest "Programme d'Investissements d'Avenir III"*. The project associating INRA and ITEPMAI, entitled HerbiScan, enters the category "Innovative Agriculture" and aims to discover and develop new herbicides of plant origin, which will be in adequacy with the stakes of the current agriculture (new active molecules more respectful of the environment).
For 50 years, the theory of the "descended larynx" has stated that before speech can emerge, the larynx must be in a low position to produce differentiated vowels. Monkeys, which have a vocal tract anatomy that resembles that of humans in the essential articulators (tongue, jaw, lips) but with a higher larynx, could not produce differentiated vocalizations.
CEA-Leti and partners demonstrate potentially scalable readout system for large arrays of quantum dots
'Results Hold promise for Fast, Accurate Single-Shot Readout 'Of Foundry-Compatible Si MOS Spin Qubits' 'SAN FRANCISCO ' Dec. 11, 2019 ' Leti, a technology research institute of CEA Tech, and its research partners have demonstrated a potentially scalable readout technique that could be fast enough for high-fidelity measurements in large arrays of quantum dots.

Since 2013, a European Union (EU) moratorium has restricted the application of three neonicotinoids to crops that attract bees because of the harmful effects they are deemed to have on these insects. Yet researchers from the CNRS, INRA, and the Institut de l'Abeille (ITSAP) have just demonstrated that residues of these insecticides-and especially of imidacloprid-can still be detected in rape nectar from 48% of the plots of studied fields, their concentrations varying greatly over the years.
