The DRF at the CEA assemble approximately 6,000 scientists since January 2016.
An interactive video has made it possible to reconstruct the trajectories of 1,400 galaxies, including the Milky Way, over distances reaching up to 100 million light years.
“Spin ice” refers to a ferromagnetic material at low temperature exhibiting a promising quantum behavior. Using neutron scattering experiments and theoretical models, a collaboration involving the Iramis has just established how a tiny chemical disorder in this material can reveal a spectrum of magnetic fluctuations. This is a fundamental step in realizing and controlling the properties of a quantum spin ice.
IBS researchers and their partners have discovered a new weapon in the Pseudomonas aeruginosa arsenal.
Certain polyoxometallates are molecules that show promise for the treatment of cancer or Alzheimer’s disease. A team from the Institut de chimie séparative at Marcoule and the University of Regensburg has analyzed their remarkable behavior in aqueous environments with respect to polar surfaces and has found numerous applications in biology as well as materials science.
Researchers at the Institut Frédéric-Joliot have provided the mapping of the hippocampus at an unequalled resolution using high field MRI. In addition to its substructures, this has revealed its internal connections and its cellular composition.
Researchers at the CEA’s BIG Institute have shown how floral stem cells differentiate to form a flower, through an epigenetic regulation that could upset the canonical models.
Tau protein aggregates observed in the neurons of people with Alzheimer’s disease are considered to be partially responsible for the disease. Researchers at the Institut François-Jacob now suggest, on the contrary, that they have a protective role.
Researchers at the Institut Frédéric-Joliot have demonstrated how the brain region specific to word recognition develops when learning to read.
Researchers from the Biam and Inra have shown how the modification of a protein in a plant leads to an effective resistance against potyviruses.
Several nuclear magnetic resonance (NMR) techniques have enabled chemists from the Inac to elucidate the surface state of ternary chalcogenide nanocrystals (CuInS2) dispersed in an organic solvent. This is a key step in providing these nano-objects with new functionalities for energy conversion, photonics and biological analysis.
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.
