The DRF at the CEA assemble approximately 6,000 scientists since January 2016.
After four years of study, the Luminescent Underground Molybdenum Investigation for Neutrino mass and nature (LUMINEU) collaboration has selected lithium molybdate for the manufacture of scintillating bolometers. These ultrasensitive particle detectors will be used for neutrinoless double-beta-decay searches. Should evidence of the latter be highlighted, neutrinos would merge with their antiparticle and the absolute mass of the neutrino would become accessible.
Physicists from IRFU have announced that no "big brother" of the Higgs boson has been detected at the ATLAS experiment at CERN's LHC. Their results rely on new analyzes with higher sensitivity.
Several decades after its discovery, dark matter remains enigmatic. Researchers from IRFU have tested three models of dark matter in which the formation of large structures was modeled using supercomputing. The reconstruction of large structures from observations of quasar spectra favors the hypothesis of a standard "cold" dark matter and sets some of the strongest constraints on these invisible masses.
Researchers at CEA-BIG have developed a web application called ChloroKB, a software that will facilitate the quantitative and predictive modeling of plant metabolism.
A European collaboration involving IRAMIS has described the fabrication of nanoporous graphene sheets that are both robust and easy to handle. The process, which can be used for large area fabrication, uses a copper/graphene/polymer 'sandwich' exposed to heavy swift-ion beam irradiation. It paves the way for numerous applications, including filtration for DNA sequencing and desalination of seawater.
A team from IRFU has reached a first milestone in the development of a detector for brain imaging which, scientists hope, will allow the measure of spatial resolution in positron emission tomography (PET) scans at the MRI level (mm3). The scientists have recently achieved the ultra-purification of a liquid similar the candidate for detection.
New research is challenging the way genes are classified in international databases. How to make a perfect match between a gene and the function of the associated protein without testing? Researchers from the François-Jacob Institute have found the answer.
Through the radiocarbon dating of calcite granules secreted by earthworms, a multidisciplinary team involving LSCE proposed the first precise chronological framework for all thawing phases in the last glacial period.
What are the mechanisms of HIV control in individuals known as "controllers"? Researchers at the François-Jacob Institute and their partners have highlighted the peculiarities of CD8+ T cells.
An international collaboration led by IRFU and Riken Nishina Center (Japan) has performed the first spectroscopy of very neutron-rich krypton nuclei 98Kr and 100Kr, using the Radioactive Isotope Beam Factory accelerator in Riken. These experiments complement the results obtained on rubidium and zirconium and deepen the knowledge on a shape transition that occurs in these three nuclei beyond 60 neutrons.

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.
