Studying the genetic diversity of human populations today reveals past demographic and migratory events that left an imprint on our genome, same as current migrations will affect our future genetic diversity.

In the animal kingdom, dispersal represents a critical decision as it affects survival and reproductive success, and is also an important component of population dynamics. This article looks at dispersal

Many factors influence dispersal decisions in animals. However, animals only disperse once they are physically fit enough to reach and settle in the new location successfully.

The first migration led some groups away from the African continent to colonize the rest of the planet and, ever since, geographical displacement of individuals or groups has remained constant throughout history (despite the restrictions currently imposed by border-control policies).

Economic restructuring in the media industry has eliminated many professional journalists’ jobs, reductions that may have been hardest on specialized journalists reporting areas like science, technology, economics, or international affairs.

Scientific journalism faces the challenge of adapting not only to new formats but also to new information exchange dynamics. New online platforms, making it easier to access and produce scientific content, are forcing science publics to evolve.

The present article reviews the panorama of science communication in France from the perspective of the monthly magazine La Recherche and other French media sources.

Communicating science effectively and rigorously is still one of the many challenges facing scientists and researchers today. Indeed, in the current context it is more important than ever to involve society in the work undertaken at universities and research centres.
