The DRF at the CEA assemble approximately 6,000 scientists since January 2016.
Researchers from the LSCE/LMC14 (CEA-CNRS-UVSQ) and the Institut de recherche de Chimie Paris (CNRS-Chimie ParisTech-C2RMF) have settled a long-standing controversy: The wax bust of Flora kept in the Bode Museum in Berlin is later than the Renaissance. To achieve this, they conducted a rigorous investigation, combining chemical analyses and carbon-14 measurements, and succeeded in meeting the challenge of dating an extract of marine animal, spermaceti.
A CEA-Joliot team is developing with the AP-HP a mass spectrometry diagnostic test for COVID-19 that would also make it possible to assess the patient’s viral load. Their aim is to make the method more sensitive and more compatible with hospital equipment.
Thanks to an original experimental setup, scientists from CEA-IRIG clarified for the first time how the response of a spin current to the perturbation brought by a ferromagnetic material depends on the orientation of the majority spin with respect to the magnetization of the material. A fundamental point for understanding spin transport in spintronic components!
An international collaboration of climate researchers including the LSCE (CEA-CNRS-UVSQ) is using a model of the Earth System to determine the different regional contributions to global warming, as well as the individual factors that modify and amplify it, such as CO2 emissions, or, on the opposite, by temporarily attenuating it, such as aerosols. This model represents a valuable tool for implementing a responsible climate policy.
Scientists at CEA-Irig, in close collaboration with CEA-Leti, achieved a unique integration of classical electronics with a quantum system. They demonstrate the possibility of measuring current through quantum dots by CMOS circuitry on a single chip cooled to 10 millikelvin, in Fully Depleted Silicon On Insulator (FD-SOI) technology.
Thanks to the first full-length record of the isotopic composition of water vapor from Svalbard (Norway), climatologists at LSCE (CEA-CNRS-UVSQ) documented the origin of winter air masses during peak moisture events.
Researchers from CEA-Iramis and their partners refute a widely accepted assertion that the coupling of a Josephson junction to a high resistance is constrained. They thus open the way to new high-impedance devices, previously considered unfeasible.
With the help of metabolomics, a study by the CEA-Joliot and its partners has improved the understanding of the complex relationship between blood glucose levels (glycemia) and the functional outcome of patients following a stroke.
The sensitivity of direct imaging of extrasolar planets could be increased tenfold by installing, under ESO supervision, the CEA-Irfu-built VISIR instrument on Yepun, one of the VLT telescopes, equipped with an integrated adaptive optics system. A 100-hour campaign in 2019 revealed an image that could be of a planet orbiting the star Alpha Centauri A 4.4 light-years away.

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.
