The DRF at the CEA assemble approximately 6,000 scientists since January 2016.
Researchers from BIAM and their partners have elucidated the action mechanisms of antioxidant compounds in rosemary.
Researchers at the François-Jacob Institute and their partners have shown that exposure to low doses of irradiation leads to function loss in hematopoietic stem cells.
In collaboration with the CEA François-Jacob Institute and INRIA, scientists from INRA have sequenced the genome of butterfly Spodoptera frugiperda. This common agricultural pest in the Americas is now moving towards the East.
For the first time, an international collaboration involving IRFU has mapped out the largest structures of the universe in 3D, from the movements of thousands of galaxies. This reconstruction includes areas which, until now, were unobservable.
Researchers from INAC have managed to accumulate high spin densities in germanium over long distances. This result opens prospects for the production of a multi-terminal spintronic device where different spin voltages can be used as inputs for magneto-logic gates on germanium.
The data collected between 2010 and 2017 by the T2K collaboration (Tokai To Kamiokande) and the reactor neutrino experiments strengthens the trend announced a year ago—neutrinos and antineutrinos have seemingly different behavior.
Synchrotron analysis combining photo-emission and X-ray fluorescence is a remarkable tool to study InGaN/GaN quantum multiwires integrated in blue GaN wire LEDs. Using this approach, scientists from INAC have broadened their understanding of how to optimize and control the growth conditions of the multiwells surrounding GaN wires.
Biologic nanomachines are complex protein assemblies that are difficult to analyze. Researchers at IBS were able to film the auto-assembly of one of them in real time.
The lifetime of a spin in graphene is very long... yet this material isn't magnetic. Seeking new applications in spintronics, researchers from INAC have used computer simulations to show that a graphene film can be spin-polarized thanks to a proximity effect with an insulating magnetic material such as iron and yttrium garnet (YIG) or a europium chalcogenide.
The ATLAS collaboration at CERN's LHC has found the first direct evidence for the rare process of high-energy light-by-light scattering, where two photons interact and change direction. This phenomenon was predicted several decades ago by quantum electrodynamics, i.e. the quantum theory of electromagnetism.

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.
