Waterproofing, fire-proofing and non-stick coating. These technologies bring safety and comfort to our daily lives, but are based on chemicals called per and polyfluoroalkyl substances or PFAS. Nicknamed “forever chemicals”, these molecules are volatile - they can be emitted by the materials they are applied on and get released into the air. There, they can linger in the environment for decades and travel vast distances, accumulating in regions far from their initial site of emission. In the…

In the forest of Plougastel, located in Finistère in Brittany, fragments of shale plates have been discovered, along with other archaeological materials. Decorated with abstract and naturalistic engravings, these tablets would date back to the early Azilian period, about 14,000 years ago. This period, still little known to prehistorians, is nevertheless important because it marks the transition between the previous period, the Magdalenian, and the Azilian, the period at the beginning of which…

Can the intonation of somebody's voice tell about their social traits? At IRCAM, researchers conducted experiments to understand how the brain was able to analyse the speech prosody of a speaker, thus demonstrating whether someone is trustworthy or has a domineering attitude towards the person they are talking to. They developed an experimental protocol to understand with which representations in mind one person makes an opinion about the personality of another. Using a phase vocoder, the…

To maximise the safety of an aircraft despite the presence of multiple holes, researchers at LMT-Cachan are trying to understand and control the mechanics of holes. One needs to drill millions of holes to assemble the structures that make up an aircraft to be assembled together, which can create weak points. Several tests are therefore carried out by engineers, who study the resistance of aeronautical materials and structures, to predict how a perforated material will eventually bend. By…

An Ecotron is a device that enables scientists to simulate several climate parameters and control them to study miniature versions of given ecosystems. A team in France decided to study Arizona savannahs. Locked in hermetic climate chambers, they analyse different plants from the savannah after accurately calibrating the surrounding light, the irrigation system, and the composition of the atmosphere. Thanks to the collected data, the team will be able to forecast the ecosystem's reaction to any…

The green sea turtle is now facing a high risk of extinction. In order to protect it, we first need to understand it better. That is why, since 2013, a team of 40 researchers and volunteers have been diving in Martinican waters to catch these reptiles. Before releasing the turtles into the ocean, they have been equipping them with satellite tags, cameras and microchips. This marking system enables scientists to follow the turtles' migratory patterns, dive behaviour, and to study the…

Décrit depuis deux siècles par des explorateurs, des ethnologues et des historiens de tous pays, le gong n'est pas seulement un instrument de musique, mais aussi un objet complexe et pluriel qui participe de l'expression de la culture de…

The atomic probe is a unique scientific instrument: it makes it possible to analyze the composition of a material on an atomic scale and to obtain a 3D model of the arrangement of atoms at the heart of matter. Its origins date back to the 1960s, when Erwin Muller (Univ.of Pennstate) developed the ion microscope to observe atoms in their individuality. The evolution of this technique will be linked to the Material Physics Group, founded by Jean Gallot at the University of Rouen. When he came…

Now a senior researcher at the national institute for demographic studies (Institut national des études démographiques - INED), he works on the public political debates on immigration in France and in the Netherlands in 2011-2012. His focus of interest is the argumentations and rethorics used, for which he created a classification and uses a…

How do you cry out "Help!" in caiman language? This is the question Thierry Aubin and Nicolas Mathevon, bioacousticians at the CNRS ask themselves. We travel with them to the marshy plains of Venezuela, where they engage sometimes in sporting experiments: capturing young caimans, recording their cries of distress, then broadcasting them to observe the mothers' reactions. The results obtained provide a better understanding of the evolution of sound communication in the animal world.
