The DRF at the CEA assemble approximately 6,000 scientists since January 2016.
Blursday, the first database dedicated to the alteration of the perception of time during the confinement imposed by the COVID-19 pandemic, has been made available to the scientific community by a consortium led by a researcher from the CEA-Joliot. This large-scale participatory study reveals that the feeling of isolation may have induced the perception of slowed time.
A Franco-German study coordinated by the LSCE (CEA-CNRS-UVSQ) estimates that climate change could shift the peak in Arctic Ocean acidity from winter to summer, which would be disruptive to the ecosystem.
The Irfu has entirely manufactured a test coil in superconducting niobium-tin (Nb3Sn), which was successfully tested at CERN. This opens the way for the development of compact magnets capable of producing a magnetic field twice as large as what is currently available, for use in future particle accelerators.
Researchers at the CEA-Irig have demonstrated that there is an optimal configuration for bringing the coherence times of hole spins closer to those of electron spins.
Nine months after its launch, the James Webb Space Telescope (JWST) has provided unprecedented images of an exoplanet. The first ever obtained in the mid-infrared, these images should revolutionize our knowledge of extrasolar planets. French astronomers, including some from the CEA-Irfu, participated in observing this planet and in designing the telescope coronagraphs.
Researchers at Irig and their partners have demonstrated for the first time that it is possible, through the simple application of a gate voltage, to change the winding direction of magnetization “nano-vortices” (skyrmions), and thus to individually control the direction of their motion. This breakthrough opens up new possibilities for research in information processing (multiplexing, etc.).
An international collaboration involving the LSCE (CEA-CNRS-UVSQ) recommends the earliest possible deployment of these technologies on a large scale. If postponed to the latter half of this century, the available biomass production would be largely reduced by climate change, jeopardizing the goal of containing global warming to 2°C by 2100, and potentially leading to food shortages.
Researchers from the CEA-Iramis and their partners at the Laboratoire de Mécanique des Fluides de Lille have been exploring the origin of irreversibility through a unique large-scale turbulence experiment.
CEA and RIKEN have been working together in the field of AI, big data and HPC for more than five years.
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.
