The return of Donald Trump to the U.

S. presidency has sparked global concern over his administration's policies on science and research.

Budget cuts, censorship, and restrictions on climate change data have alarmed scientists worldwide.

In response, French universities like Bordeaux and Aix-Marseille are rallying to support American researchers.

Bordeaux is hosting protests to highlight the suppression of scientific freedom, while Aix-Marseille has launched programs to welcome censored U.

S. scientists, particularly in climate and health fields.

These actions reflect a broader international effort to defend academic freedom and the role of science in democracy.

Critics warn that Trump's policies could undermine the U.

S.'s historical leadership in global scientific innovation.
