The DRF at the CEA assemble approximately 6,000 scientists since January 2016.
Publication of a large set of interdisciplinary simulations to which researchers from LSCE (CEA-CNRS-UVSQ) have contributed offers an opportunity to assess the future impact of the melting of the polar ice caps. What are the trends and uncertainties?
Researchers at the CEA-Irig have developed a new concept in nanomaterials involving an assembly of silver nanoparticles linked by a bio-inspired molecule.
On August 19, 2020, the European consortium SpinTronicFactory, led by the French laboratories[1] Spintec (CEA, CNRS, Université Grenoble Alpes) and Thales-CNRS Joint Unit (Palaiseau), published an ambitious spintronics road map in Nature Electronics. The field, at the frontier between magnetism and microelectronics, is coming of age, and offers wide possibilities for innovation.
With the help of X-ray and neutron scattering measurements of model nanoparticles, a team from the Iramis is developing recommendations for the use of functionalized gold nanoparticles in anticancer therapy: the polymer crown must be made from hydrophobic, positively charged monomers.
A bacterium present in our intestinal macrobiota produces a particularly interesting antibiotic: Ruminococcin C1. Explanations from CEA-Irig.
A NeuroSpin team, in collaboration with researchers from SHFJ and MIRCen (CEA-Jacob), is identifying a predictive indicator of the potentially deleterious effect of devices using ultrasound to deliver drugs to the brain.
A team from CEA-Joliot in Marcoule detected by mass spectrometry, in 3 minutes and without specific reagents, signature peptides of the SARS-CoV-2 virus in clinical samples (nasopharyngeal swabs). It thus provides a proof of concept of the use of this method as a possible alternative to PCR, currently the reference method.
Researchers at the CEA-Iramis and their partners have locally grafted organic molecules onto gold nanoparticles, using two photopolymerization steps. This new flexible functionalization technique can be used for applications ranging from biosensing to photonics.
According to an international collaboration involving the LSCE (CEA-CNRS-UVSQ), the doubling of atmospheric CO2 content compared to the pre-industrial era would “probably” warm the earth between 2.6°C to 3.9°C. This assessment – the best to date – is based on three independent data sources that do not use climate models.
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.

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.
