François Jacob 2025 Day

The Living Clock: Biology in the Flow of Time
François Jacob

On December 3, 2025, the Collège de France is hosting the Journée François Jacob "The Living Clock: Biology in the Flow of Time", organized by the Institut de biologie du Collège de France.

Every year, the Journées François Jacob, organized by the Collège de France's Institute of Biology, bring together leading specialists from France and abroad to discuss a theme at the cutting edge of biology research.

They are named in honor of François Jacob, holder of the Cellular Genetics Chair at the Collège de France (1964-1991), who was awarded the 1965 Nobel Prize in Physiology or Medicine along with André Lwoff and Jacques Monod for his discovery of the genetic regulation of enzyme and virus synthesis.

This year, bringing together specialists in genetics, developmental biology, neuroscience and evolutionary biology, the day explores the multiple ways in which biology is inscribed in time, across scales, levels of organization and disciplines.
