This week in A LUM LA SCIENCE, Guillaume Maurin, researcher at the Charles Gerhardt Institute in Montpellier, is our guest. With his team, he has just developed a new membrane that improves the economic and ecological cost of gas purification. In the second part, Bernard Mongellaz shows us the cold laboratory of the University of Montpellier.
Our species is acclimatised to a world of constant gravity - in this case, a pervasive force of acceleration arising from the Earth's attraction (the unit of gravity, g, is 9.81 m/s2 ). There are, however, circumstances where our bodies are subjected to more than the classical Earth gravity... This is again a matter of acceleration.
This week in A LUM la science, Wilfried Sanchez, deputy scientific director of Ifremer, presents the results of the Inrae-Ifremer collective scientific expertise on the impact of phytopharmaceutical products on biodiversity and ecosystem services.
Every day, they drink water heavily contaminated with arsenic. And yet these inhabitants of the Altiplano in Bolivia do not seem to suffer from it... An enigma that the epidemiologist Jacques Gardon has investigated and reveals how they have adapted to this poison.
The results of the presidential election led many observers to believe that France would be divided into three poles: a governing centre, a right-wing grouping its conservative and extremist currents, and a left-wing grouping mostly its radical pole.
This image was taken during the formation of a membrane of ultra-porous material, which allows molecules to be 'sieved' or trapped. These materials are being developed, for example, for separating gas mixtures, cleaning up air or water, or delivering the active ingredients of drugs more efficiently.
