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.
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.
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.
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.

EBRAINS (European Brain ReseArch INfrastructureS) is a european research infrastructure designed by the scientific community which, based on a set of state-of-the-art digital platforms, aims to answer the analysis and processing needs of large brain data sets. CEA carries for France EBRAINS inscription on the European Strategy Forum on Research Infrastructures roadmap, which was submitted in early September 2020.

The recently launched EU-funded project GAIN4CROPS aims to improve photosynthetic efficiency of the oil crop sunflower using nature-inspired solutions and innovative breeding techniques. The 5-year 8M € project, funded under the EU Horizon 2020 Framework Programme, will pave the way for the introduction of strategic crops which might decrease the use of major resources in agriculture: land, nitrogen, and water.

This summer, after being shut down for 20 months, the ESRF (European Synchrotron Radiation Facility) has once again opened its doors to scientists, boasting an X-ray source that is one hundred times more brilliant than before (the EBS, Extremely Brilliant Source). Researchers at the Interdisciplinary Research Institute of Grenoble (CEA-IRIG) are involved in designing new experiments using the new beamlines, which are smaller, more brilliant and more coherent.
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.
