The mathematics community mourns the loss of Maryam Mirzakhani, aged 40 and mother of a little girl. We express our deepest condolences to her family and friends. Specialist in Teichmüller theory, hyperbolic geometry, ergodic theory and symplectic geometry, Maryam was the first woman awarded with the Fields medal in 2014.
Researchers from Reims university (France) recently modelled the biodiversity of a socio-ecological system of the forest of the Ardennes (France). Their work aims to simulate the evolution of a tree population in that forest, in order to analyse the influence of climatic changes on its behavior.
The Grothendieck archives in Montpellier university contain unpublished manuscripts, particularly dealing with algebraic geometry, which account for the major part of Grothendieck's works between 1949 and 1991.
Anna Cadoret and her collaborators have recently proved the analogue of the celebrated theorem that Deligne published in 1980 [D80]. The latter was established for l-adic cohomology while the result of [CHT17] holds for étale cohomology with finite coefficients.
Can we predict how we shall earn when playing pinball? How could we mathematically modelize a pinball of infinite size? Actually, a pinball can be understood as a chaotic dynamical system, with close links to kinetic theory of gas.
What are the mathematics behind the results of the physicists David J. Thouless, F. Duncan Haldane and J. Michael Kosterlitz, for which they were awarded the 2016 Nobel Prize? 
The French mathematician Mathieu Lewin explains what topology has to do with it.
The Société Mathématique de France launches a mathematical challenge dedicated to undergraduates and graduates: 10 days to solve 10 mathematical problems, picked among research topics which have not yet yielded publications. A research challenge for younger students! Note that students may compete as teams of 1 to 3 candidates.
Concours SMF junior starts on May 2nd and closes on May 11th: teams may enrol until the last day of the competition. Click here for registration.
On June 1st, 2017 at the Collège de France in Paris, mathematicians will pay tribute to Jean-Christophe Yoccoz. The lectures will be addressed to non-specialists.

Laurent Fargues, Jean-François Le Gall, Benoît Perthame et Bertrand Toën, were awarded a ERC Advanced Grant. Congratulations to all four of them!
Julien Jouganous was awarded the 2016 'Le Monde' Research Prize for his PhD entitled Lung metastases growth modeling and simulation, which he did under the supervision of Olivier Saut at the Institut de Mathématiques de Bordeaux (CNRS, Université de Bordeaux, Bordeaux INP), and which he defended on September 2015, 23.
