The DRF at the CEA assemble approximately 6,000 scientists since January 2016.
Researchers from the CEA-Iramis and their partners at the Laboratoire de Mécanique des Fluides de Lille have been exploring the origin of irreversibility through a unique large-scale turbulence experiment.
CEA and RIKEN have been working together in the field of AI, big data and HPC for more than five years.
A method known as quantum key distribution has long held the promise of communication security unattainable in conventional cryptography. An international team of scientists has now demonstrated experimentally, for the first time, an approach to quantum key distribution that is based on high-quality quantum entanglement — offering much broader security guarantees than previous schemes.
Researchers at the CEA-Joliot (NeuroSpin) have succeeded in systematically decoding the cognitive activity associated with various brain activation patterns as recorded by functional MRI. This feat was achieved using neural networks trained on the largest public brain imaging database.
Based on experiments conducted in the European tokamak JET, physicists from the IRFM and their partners demonstrated that the increased presence of highly energetic deuterium ions improves the stability of the fusion plasma. ITER’s plasma should benefit from a similar effect, thanks to the helium nuclei produced by fusion.
A French-South American consortium led by the LSCE (CEA-CNRS-UVSQ) is working to explain the chronology and spatial distribution of radionuclides deposited in South America following atmospheric nuclear testing. Their research, based on measurements of plutonium isotopes in soil and sediment samples, will enable the precise reconstruction of the evolution in land use since the 1960s.
Researchers from the CEA-Irig and their Vietnamese partners have developed an artificial leaf capable of converting solar energy into hydrogen, with a 2% conversion yield. This is a promising achievement towards the storage of renewable energy sources!
Using almost fully automated processes, researchers at Irig have designed a three-dimensional microenvironment in which cells form a tissue resembling a mini-tumor. Their work opens new perspectives for personalized medicine.
Researchers at the CEA-Joliot (NeuroSpin), in collaboration with the Gustave Roussy Institute, the Necker Hospital and the Curie Institute (Orsay), have proposed an original method for analyzing MRI images of rare brain tumors, by combining automatic object detection and deep learning segmentation for common tumors.
Studies carried out by the CEA-Joliot show that simultaneous PET/MR imaging noticeably improves the detection of lesions responsible for epilepsies, as well as the preparation of the surgical interventions used to treat them.

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.
