The Planck satellite started to observe the universe in August 2009. In 2013, the images collected enabled scientists to extract information about the structure of the universe, focusing their research on polarization in 2014. It is a property attributed to light which is the latest testimony of the interaction between light and matter. The photos made by Planck provide a high quality atlas of the universe showing matter clusters. Scientists explain what the universe is made of, and what is at…

At the occasion of the bicentenary of Evariste Galois ' s birth, this film evokes the life and the work of one of the greatest mathematics genius, whose theory has revolutionized modern mathematics and physics. Born in 1811, he died at the age of 21 following a duel. He discovered the world of mathematics at the age of 16 and his papers were refused by the French Académie des Sciences. His theory started to be recognized and understood only 30 years later.

This is a series of high definition short films revealing a whole range of planktonic organisms collected in the Mediterranean and the Indian Ocean during the first year of the Tara schooner oceanic expedition. Propelled by eight rows of combs, pleurobrachia deploy two long tentacles to fish for crustaceans. It is the oldest known species to have developed a neurosensory system. By studying it, biologists hope to discover how the first neurons appeared.

There are continual exchanges between a cell's cytoplasm and its nucleus. In 1997, a team led by Catherine Dargemont of the Institut Jacques Monod was the first to develop a method for extracting proteins from the nucleus. Since then this laboratory has focused on several areas: the mechanisms regulating the exchanges; the mechanisms for transporting RNA and in particular the stage of translocation of the transport complexes in the cytoplasm; understanding how certain viruses like HIV make use…
