The DRF at the CEA assemble approximately 6,000 scientists since January 2016.
A mere seven months into its five-year mission, the Dark Energy Spectroscopic Instrument (DESI) has already collected 3D mapping and spectral data from more than 7.5 million galaxies and quasars, breaking all previous records! The complete map will allow cosmologists to better understand the dark energy that drives the expansion of the Universe.
While France is taking over the Presidency of the European Union, and in a context of strengthening bilateral cooperation between France and Italy - highlighted by the signature of the Quirinal Treaty by President Emmanuel Macron and Italian Prime Minister Mario Draghi on 26 November - CEA, CINECA and GENCI have engaged a joint initiative aimed at strengthening European digital capacity.
By analyzing the blood lipidome of patients with cirrhosis, a European collaboration involving the CEA-Joliot has discovered specific biomarkers for the different stages of the disease. This is an important step towards achieving a personalized and more effective management of this illness.
An international collaboration involving the CEA-Irfu has discovered the largest group of “rogue” planets to date, thanks in particular to a very sensitive “mega-camera” built by the CEA and deployed since 2003 on the Canada-France-Hawaii Telescope.
According to a collaboration coordinated by the LSCE (CEA-CNRS-UVSQ), it is necessary to take into account the biophysical effects of bioenergy crops (including CO2 capture and sequestration) in order to properly assess their effectiveness in the fight against climate change.
Researchers at the CEA-Irig have partly lifted the veil on the extraordinary resistance of a small animal, the tardigrade. At play is a disordered protein capable of transforming itself into a protective gel for other biomolecules during drought or extreme cold.
According to researchers from the CEA-Iramis, it is now possible to detect spins thanks to an original method using a single photon sensor that is insensitive to noise. This is a major step forward for the measurement of spin quantum bits or their conversion into photons.
Using an electronic analog of a Mach-Zehnder interferometer, researchers from the CEA-Iramis and their partners observed for the first time the electric dipole associated with spin waves (magnons) in a ferromagnet in the quantum Hall regime. These spin waves could be used in particular to transfer information from one quantum bit to another.
Researchers from CEA-Iramis have demonstrated that, contrary to what is generally believed, the electronic spin carried by erbium can have a long coherence time. This makes it a good candidate for relaying quantum information via photons.
The LSCE (CEA-CNRS-UVSQ) and the EDYTEM laboratory (CNRS - Université Savoie Mont Blanc - Ministère de la Culture) have established a comprehensive overview of cesium-137 fallout observed in sedimentary archives around the world. This database makes it possible to improve the dating of sedimentary cores.
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.
