The DRF at the CEA assemble approximately 6,000 scientists since January 2016.
A study on the effects of hydroxychloroquine in macaques infected with the SARS-CoV-2 virus, used alone or in combination with azithromycin, have been published on Nature; the 22th oh july. Scientists from the CEA, CNRS, Inserm, Institut Pasteur, Université de Paris-Saclay, Université Claude Bernard Lyon 1 and Aix-Marseille Université have been involved in the study, which has been carried out under the aegis of the multidisciplinary consortium, REACTing.
An international consortium of scientists, including the Laboratoire des Sciences du Climat et de l'Environnement (LSCE - CEA/CNRS/UVSQ, Institut Pierre Simon Laplace, Université Paris-Saclay), used a new method to refine the map of caesium and plutonium radionuclide concentrations in soils in France and several neighbouring countries.
CEA-Joliot researchers and their partners have used a large-scale approach to map and characterize the response of CD4 T cells from healthy donors to two proteins of the Ebola-Zaire virus. They suggest that one of these proteins could be a target in the design of new vaccines.
Chemists at Iramis have proposed a new pathway for the catalytic synthesis of methanol from a formic acid derivative – a waste product of the silicon industry – whose by-products can be recycled. This is a high-yield, sustainable and environmentally friendly process that can be used for energy storage and fine chemistry!
With virtually zero background noise, the CUPID-Mo experiment at the Modane Underground Laboratory, in which the CEA-Irfu is participating, is setting a new non-detection limit for the hypothetical “neutrinoless double beta decay” (0νββ), which has never been observed. If it occurred, this detection would prove that neutrinos are their own antiparticles and would explain the predominance of matter over antimatter in the Universe.
Researchers at the CEA-Joliot (I2BC) have used NMR to decipher a novel mechanism in breast cancers linked to the BRCA2 gene.
For the first time, wall paintings from the Late Middle Ages in a castle in Burgundy and a church in Switzerland have undergone absolute dating, by measuring the carbon-14 contained in a pigment widely used in the paint, namely lead white.
A CEA team, in collaboration with the Pablo de Olavide University (Seville, Spain) and the Swiss company Solaronix, has invented a new family of photochromic dyes for photovoltaics. The result of this work paves the way for photovoltaic glasses whose transparency adapts to the luminosity, an interesting application in particular in the buildings and automotive sectors.
A team from the CEA-Iramis has shown that it is possible to bring an ensemble of electron spins to a temperature lower than that of the supporting crystal, thanks to their being coupled to an electromagnetic field within a resonant microwave cavity. This patented discovery greatly improves the detection of EPR (Electron Paramagnetic Resonance) and NMR (Nuclear Magnetic Resonance) signals.
The CEA-Irig (IBS) has reported in Nature Catalysis a review on SAM proteins, a type of catalyst that produces highly reactive radical species.

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.
