The DRF at the CEA assemble approximately 6,000 scientists since January 2016.
When immersed in biological media, nanoparticles are immediately "wrapped" in proteins. A study conducted by researchers from the Iramis and Joliot (I2BC) institutes clarifies the importance of protein size on the formation of this envelope and recommends better consideration of this parameter in proteomic and nanotoxicological studies.
Physicists from the IRFM explain for the first time why, contrary to what is observed in most tokamaks, tungsten atoms from the inner walls do not accumulate in the WEST fusion plasma. ITER should also be free of this contamination, which degrades plasma performance.
Researchers at the CEA’s Jacob and Joliot Institutes have improved the monitoring of brain inflammation in Parkinson’s disease patients with PET imaging, using a molecule called [18F]-DPA714. This radiotracer could be useful for evaluating anti-inflammatory drugs specific to this disease, and for monitoring the inflammatory process in other neurodegenerative pathologies.
A collaboration involving CEA-Irig has succeeded in setting in motion an 18-µm-long mechanical oscillator by optically exciting an embedded artificial atom. This result is an important step towards the realization of interfaces that connect the quantum and classical worlds.
A theoretical physicist at the IPhT and his partners at the EPFL (Switzerland) and MIT (USA) have just revealed a temporal form of quantum entanglement. For the first time, this has allowed them to demonstrate a very strong entanglement between a photon and a phonon, in a diamond crystal at room temperature. Their experiment makes it possible to probe the coherence of single phonons on very short time scales, which opens the door to the search for materials for ultrafast quantum technologies.
A study involving the CEA-Joliot has revealed the mechanism by which certain depressive states are linked to an imbalance in gut microbiota. The endocannabinoid system makes the connecting link.
According to a collaboration involving the LSCE (CEA-CNRS-UVSQ), chlordecone has reappeared massively in the French West Indies since the end of the 1990s - when the use of glyphosate was introduced - years after it was banned.
Researchers from the CEA-Jacob and Claude Bernard University have identified a new radiosensitivity signature in patients with severe side effects following radiotherapy.
A collaboration between the LSCE (CEA-CNRS-UVSQ), the INRAE and Brazilian and Uruguayan universities established a first map of radioactive cesium deposits, following the nuclear tests of the 1960s. This map is a reference for sciences, which will allow the of soil erosion and redistribution in South America.

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.
