The DRF at the CEA assemble approximately 6,000 scientists since January 2016.
For the first time, IRAMIS researchers have isolated complex ion pairs in the gas phase and were able to characterize them using UV and infrared spectroscopy. This original experimental approach will deepen the scientists' understanding of extremely diverse physicochemical processes in media as varied as biological cells and batteries.
Using new computer simulations, a collaboration involving scientists from IRFU explained why the Sun's magnetic field changes polarity every 11 years. This groundbreaking discovery of a scaling law on the duration of the magnetic cycle of stars will lead to a better understanding of the risks associated with space weather forecasting.
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.
The massive rural exodus currently occurring in China is accompanied by a moderate decline in fine particulate matter emissions throughout the country, with the exception of megacities such as Beijing and Shanghai. Such is the counter-intuitive conclusion of an international study involving LSCE.
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.
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.
