The DRF at the CEA assemble approximately 6,000 scientists since January 2016.
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.
Researchers from the CEA Frédéric-Joliot Institute have identified photosynthesis mechanisms that protect plants from excessive sunlight, with the idea of mimicking them to optimize solar technologies.
By studying the iridates, a family of materials with strongly correlated electrons, researchers from IRAMIS unexpectedly highlighted a profound analogy between these compounds and high-temperature cuprate superconductors (YBaCuO). Besides their very promising potential, notably in spintronics, these materials could provide valuable clues to understand, at last, the origin of unconventional superconductivity in cuprates.
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.
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.
In a cohort of 100 patients at the Saint-Louis Hospital in Paris (Assistance publique – Hôpitaux de Paris), researchers from CEA and Paris-Diderot University have demonstrated that the level of certain immune cells in the blood is a predictor for bladder cancer recurrence and tumor progression. They suggest using this patented blood test to predict recurrence for other types of cancer.

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.
