Affaiblissement financier et humain, montée des attaques idéologiques, émergence de l’intelligence artificielle… La communauté scientifique est confrontée à de nombreux défis, à l’image du CNRS, victi...

Ancient pathogen DNA from animals elucidates the origin and evolution of infectious diseases

Preliminary reconstruction of the current MV Hondius Andes virus outbreak sequences Note on data use This is an informal analysis of currently available consensus sequences and is not intended as a fo...

After the last ice age, species migrated into a newly deglaciated Scandinavia. Brown bear recolonization is thought to have occurred from two direc...

Genomic analyses of heartworms from multiple continents suggest a deeper evolutionary origin in canids than previously recognised, with evidence of both ancient dispersal events and more recent introd...

Direct studies of long-term RNA virus evolution are largely limited to chemically-fixed specimens from natural history and pathology museums collected over the past two centuries. Detecting genomic tr...

Barreat et al. describe the discovery of deltavirus genomic fossils (ẟEVEs) in multiple species of termites. The wide expression of ẟEVEs in termites and a host gene fusion indicate that some ẟEVEs ma...

To rehabilitate the general view of women's contributions to the history of science, the CNRS is part of a commission that aims to inscribe

The propensity to endogenize and domesticate dsDNA viruses depends on lifestyle in Hymenoptera.

The International Committee on Taxonomy of Viruses (ICTV) holds a ratification vote annually after review of newly proposed taxa by ICTV Study Groups and members of the virology community. In March 20...

The reliability of ancient DNA (aDNA) authentication depends on detecting characteristic damage patterns, particularly cytosine deamination at fragment ends. However, in ancient metagenomic studies, s...
