Researchers at the Plasma Physics Laboratory have proposed a model for the transport of electrons in plasmas used in satellite thrusters. Their work made the cover of the journal Physics of plasmas in June 2020.
The European Louis Bachelier Prize is awarded this year to Mathieu Rosenbaum, professor at the Centre for Applied Mathematics at the École Polytechnique. This prize recognises major contributions to mathematical modelling in finance and financial risk control.
An international collaboration has shown that the very high-energy gamma-ray emission from quasars, galaxies with a highly energetic nucleus, is not concentrated in the region close to their central black hole but in fact extends over several thousand light-years along jets of plasma. This discovery. This work is published in the journal Nature.
Researchers at the Laboratoire pour l’utilisation des lasers intenses have evidenced magnetic fields generated by “Weibel” instabilities developing over surprisingly large distances in a laser-irradiated plasma. This phenomenon, interpreted with the help of CEA researchers, could explain gamma bursts and cosmic rays in astrophysics.
An international collaboration to which Marc Graille's team, CNRS Research Director at the Laboratory of Structural Biology of the Cell, is contributing has identified an important enzyme that acts on the ribosome and allows normal development of the animal brain and normal walking in Drosophila.
"Optimizing the shape of multiphysical systems" and "Understanding decision-making under risk and delay": these themes earned the young doctors Florian Feppon and Tomáš Jagelka the recognition of their peers. Their theses are awarded “best thesis” in applied mathematics and economics respectively.
A consortium of doctors and researchers developed ICUBAM, an application to monitor the availability of intensive care beds in the COVID-19 crisis. ICUBAM was quickly adopted by doctors in intensive care units in the Grand Est and then in 40 French departments.
Developed within the Leprince-Ringuet Laboratory, the PEPITES monitor can measure the parameters of charged particle beams without disturbing them. Designed using technologies used for solar sails, this prototype offers promising prospects for particle physics or proton therapy.
Data from the T2K international experiment in Japan tend to show a strong violation of matter-antimatter symmetry in neutrino oscillations. These results, in which the research team of Michel Gonin, CNRS Research Director at the Leprince Ringuet Laboratory participates, are published in the leading scientific journal Nature.
By taking interactions between households into account, Michael Benzaquen, researcher at the CNRS and holder of the chair « Econophysics & Complex Systems » and his team renew the macroeconomic model used in monetary policies. They highlight narratives as a tool to prevent depression.
Economic and social consequences of the lockdown to fight the Covid-19 pandemic argues for a fast exit strategy. Olivier Gossner and Christian Gollier, two economists working respectively at Ecole polytechnique and the Toulouse School of Economics are vying for group testing to address the Covid-19 tests shortage and speed the recovery process.
The 2020 Nicholas Kurti Science Prize was awarded to Landry Bretheau, assistant professor at Institut Polytechnique de Paris, and to Rebeca Ribeiro-Palau, CNRS researcher from Université Paris-Saclay.
Due to the closure of the school and the strict access restrictions on campus, the existing procedures regarding lab access and the continuation of research activities have been updated.
The outbreak of the Covid-19 epidemic in the Chinese province of Hubei has outlined the growing footprint of China on global value chains, according to a research paper from Institut Polytechnique de Paris and Institut des Politiques Publiques.
