The DRF at the CEA assemble approximately 6,000 scientists since January 2016.
The Captot heavy metal sensor, developed by the Iramis-LSI over the last ten years, could be used to detect traces of uranium in water. This would be a simple, rapid field solution to monitor the environment, for example during the cleanup and dismantling of nuclear facilities.
Researchers at CEA-IRIG have used NMR to reveal the molecular mechanisms that support the adaptation of avian influenza virus from birds to humans. By uncovering the secrets of the interactions between the mutated viral polymerase and a key transcription factor in host cells, this new insight will make it possible to study the mechanism of cross-species contagion of these viruses and thus open up potential new therapeutic avenues.
For the first time, a team of researchers was able to measure and accurately identify daughter nuclei produced by the fission of uranium-239 fission. This was made possible by the unique combination of GANIL equipment and beams. It is published in the Physical Review Letter*.
After winding, the seventh and last coil of FRESCA2 left Saclay in June 2019 in its reaction mould, putting an end to Irfu's activity on this project, which began in 2009 in collaboration with CERN. This type 3-4 coil is a spare coil, which, after reaction, instrumentation and impregnation at CERN, will join its type 1-2 sister on CERN shelves.
Cern turned to the expertise of the DSBT to create a heat exchanger for the HL-LHC collider. This exchanger represents a technical feat in terms of compactness and performance, leading the CERN to commission the DSBT to carry out optimization, industrialization and cold tests with a view to installing exchangers in the superconducting magnets and then in the LHC tunnel by 2022.
Following the accident at the Fukushima nuclear power plant, in 2011, the Japanese authorities decided to carry out major decontamination works in the affected area. The EGU is publishing a synthesis of approximately sixty scientific publications that together provide an overview of the decontamination strategies used and their effectiveness.
Teams from CHU Dijon-Bourgogne, Inserm and the CEA have just produced genome analysis results for very sick newborn babies in neonatal intensive care, shortening the analysis time to 38 days compared to an average of 18 months at present.
A Franco-Indian collaboration has identified an important mechanism involved in the transmission of antibiotic resistance, which is the principal cause of the failure of therapies aiming to eradicate Helicobacter pylori, a bacterium that infects half the world’s population.
New results from the Tara Oceans expedition, led by a collaboration between the Tara Ocean Foundation and teams from the CNRS, EMBL, CEA, Sorbonne Université and Université Paris Science Lettres between 2009 and 2013 show that the diversity and functions of planktonic species in the global ocean change dramatically according to latitude.
‘First light’ for the Dark Energy Spectroscopic Instrument (DESI): as the installation phase nears completion, this new instrument is due to undergo final tests before starting to create a giant map of the sky in early 2020.
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.
