The DRF at the CEA assemble approximately 6,000 scientists since January 2016.
Physicists from IRAMIS were successful in producing images of the antiferromagnetic order in bismuth ferrite by generating a second harmonic using a femtosecond laser. This result is the first step towards the control of these materials which are seen as promising for data storage applications.
To ascertain the "strangeness" property of the proton, an international collaboration including IRFU has produced, starting from protons, other particles containing a "strange" quark and characterized them. These high-precision measurements carried out at CERN in Geneva will lead to a better understanding of the contribution of strange quarks to the nucleon's spin.
The heat waves experienced in Europe in 2017 were a result of global warming induced by human activities. Every summer, there is now a 10% chance of seeing a summer as hot as 2017, as shown by an international collaboration involving researchers from LSCE.
The cow could be a relevant model to study human genetic abnormalities, as demonstrated in an international study involving scientists from the François-Jacob Institute.
A collaboration involving IRAMIS has characterized the paradoxical properties of ionic liquids— electrolytes which appear as either strong or weak depending on the scale that they are probed—and inferred a path to improve their electrical conductivity. Confined in carbon nanotubes, the electrolyte under scrutiny is very stable at high temperature and could be put to good use in batteries or fuel cells.
The WEST tokamak is now equipped with an infrared thermographic endoscope developed by IRFM. Its very high spatial resolution (100 microns) will enable researchers to study the thermal behavior of a critical component in ITER, the divertor, in great detail.
A team of scientists from the Frédéric-Joliot Institute and their partners have shown that a genetic variant associated with multiple psychiatric disorders alters a prefrontal-limbic network, that is suspected to increase the risk of schizophrenia or bipolar disorder.
Researchers from joint laboratory VECT'OLEO (Marcoule Institute for Separative Chemistry, Hallstar-France) have used an experimental model system and computer simulations to study the structuration of a vegetable oil and optimized it for the extraction and dispersing of bio-active molecules applied to cosmetics.
Researchers from INAC have used a biomimetic approach to analyze the interactions of uranium with the biological molecules involved in the toxicity of this element. Phosphoproteins appear to be priority targets.
The standardization of metagenomic methods is a prerequisite to better understand the human gut microbiota. The step of DNA extraction in this method is critical.

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.
