Notre tribune de scientifiques pour alerter sur les dangers de la nouvelle loi d'urgence pour l'agriculture: la science montre que l'urgence est au contraire de transformer le système agricole pour préserver notre santé, la fertilité des sols, une eau disponible et non polluée, et la biodiversité.

Interested in adaptive genomics, genomic offset and simulations? This seems to be an extraordinary opportunity to work with Thibaut Capblancq and Olivier François, two excellent experts in the field (and also great people)

CAMELIA workflow for model training: Stacked species distributions from S-SDMs trained with community observations and environmental variables, and community indices (species richness (SR), community mean (CM) and community standard deviation (CSTD) of various traits) are given to the multilayer perceptron. The parameters of the multilayer perceptron are then optimized by minimizing the final combined loss function that compares predicted species presence probabilities and community indices with observed community values. BCE and MSLE correspond to the binary cross-entropy loss function and the mean squared logarithmic error.

Flottille pour Gaza : à Paris, une manifestation contre « la honte » et « l’impuissance » Des centaines de personnes se sont rassemblées jeudi place de la République en soutien à la flottille Global Sumud. Et surtout pour huer des autorités accusées de ne rien faire pour les quelques dizaines de Français à bord, ou pour faire cesser la guerre génocidaire à Gaza.

To celebrate the genomes for 1,000 (!) species of Lepidoptera in Europe, Project Psyche has released a preprint outlining our ambitions to jointly sequence & leverage genomes of all 11,000 species in Europe to propel science, conservation & society.

This was a joy to write together as a community!

Infographie montrant l’évolution des exportations d’armement français vers Israël entre 2015 et 2024, en se basant sur le montant des prises de commandes.

Avec 21,6 milliards de commandes, l’industrie militaire française a connu en 2024 sa deuxième meilleure année. Dans le même temps, les exportations d’armes à destination d’Israël ont atteint un montant inégalé depuis huit ans. Et ce malgré le génocide en cours. www.mediapart.fr/journal/inte...

A new study tracks the recent and rapid diversification of glasswing butterflies, which evolved within the last two million years in the tropics of South America.
