The DRF at the CEA assemble approximately 6,000 scientists since January 2016.
For the first time, a team from Biam is showing the transcription of DNA into messenger RNA in the cells of young plants, in real time and with an unprecedented resolution. This exceptional live work reveals highly useful information on the biological mechanisms linked to the plant’s response to its environment.
A mock-up of a high-power travelling wave antenna has been successfully tested at the IRFM. This new family of antennas operates at a lower voltage than current antennas, requires fewer adjustments, and can be deployed inside the tokamak. In short, it is better adapted to the hostile environment of a tokamak!
A team from the NeuroSpin (CEA-Joliot), in collaboration with Inserm (Tours), has published the first anatomical atlas of the human brain stem using mesoscopic resolution ultra-high field MRI. This atlas, freely accessible as a wiki, will be used in particular by neuroanatomists and neurosurgeons to help them in their procedures.
Researchers from the CEA-Joliot, the Collège de France, the CNRS and the University of Paris 8 have shown that humans possess a universal capacity to understand abstract geometric concepts. In contrast, this ability, which does not depend on age, culture or education, does not exist in any of the studied non-human primates.
It is as if a microwave photon interacting with a small superconducting junction was split into several photons of lower energy! This is the scenario proposed by an IRIG researcher to interpret recent experiments using a network of superconducting Josephson junctions.
Relying on more than 60,000 computational simulations of stellar “lives”, an international team involving the Irfu has “profiled” the stars that are likely to form black hole duos with the ability to merge. Their study points to a critical phase in the evolution of the binary system, the “common-envelope phase”, which may play a decisive role.

CEA is a French government-funded technological research organisation in four main areas: low-carbon energies, defense and security, information technologies and health technologies. A prominent player in the European Research Area, it is involved in setting up collaborative projects with many partners around the world.
