The DRF at the CEA assemble approximately 6,000 scientists since January 2016.
Using an approach combining experimentation, characterization and multi-scale modeling, researchers from Iramis and their partners from the Direction des énergies and Andra have studied the corrosion of glass and metal in particular conditions of radioactive waste storage.
The data collected in 2019 by the KATRIN collaboration, in which CEA-Irfu participates, had made it possible to constrain the mass of neutrinos in an unprecedented way, leading to the world best upper limit for direct measurements. Another analysis of these same data reveals that they do not contain the signature of a hypothetical sterile neutrino. The experiment will continue, with increasing sensitivity, until 2024.
According to a study carried out by scientists from the LSCE (CEA-CNRS-UVSQ), CNRS and the Muséum national d’histoire naturelle, an isotopic analysis of strontium reveals the Indian origin of archaeological cottons dating from the 2nd-3rd centuries, in southeastern Arabia.
Noting the inconsistencies in health policies aimed at combating COVID-19, a mathematician from the LSCE (CEA-CNRS-UVSQ) and his co-authors are calling attention to the poor quality of available data, as well as the intrinsic sensitivity of epidemiological models to these data. According to them, it is impossible to make predictions about the number of infections without a thorough understanding of the non-linearities underlying the dynamics of a “complex system”, such as an epidemic.
Researchers at the CEA-Irig and their partners have provided the first demonstration of the potential of “spin-torque nano-oscillators” for use in microwave spectrum analyzers. These ultrafast devices with their nanosecond-scale resolution are proving to perform very well.
Created in 2015, the independent network MedECC (Mediterranean Experts on Climate and Environmental Change) has published its first evaluation report, MAR1 (Mediterranean Assessment Report), accompanied by a summary for policy-makers. This publication earned the group the Council of Europe’s North-South 2020 Prize. Read on for a close-up on ‘Ecosystems’, a chapter from the report that features an LSCE researcher as “lead author”.
A researcher at the CEA-Irig and his partners have demonstrated that a real (and therefore imperfect) quantum computer is several billion times easier to simulate than a perfect quantum computer! Their conclusion: before increasing the number of quantum bits, it is essential to improve their fidelity.
How did Evolution shape the architecture of neural networks? A CEA-Jacob team describes these networks in one of the smallest and most genetically distant primates from humans.
The CEA-Jacob and his partners teamed to compare FLASH radiotherapy to conventional radiotherapy in the setting of acute lymphoblastic leukemia.

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.
