The DRF at the CEA assemble approximately 6,000 scientists since January 2016.
Scientists from INAC have created an original system for mapping magnetic fields at a micronic scale, in a quantitative manner, and in real time. Its principle consists in observing the deformation across a field of thin, magnetic, light-reflecting “nanoribbons”.
The electronic noise of an NMR device is modulated by the nuclear spins of a sample placed inside the detecting coil. Scientists from IRAMIS have succeeded in building an analytical model to interpret this NMR signal of “spin noise”. This new approach makes it possible to measure tenuous isotopic effects, and provides NMR with a dramatic gain in “spectroscopic” sensitivity.
An international collaboration has discovered that large populations of bacteria in solution can spontaneously perform oscillating collective movements. A theoretician from IRAMIS showed that this observation illustrates a new long-range order emerging from local couplings between neighboring cells. This advance may inspire new strategies to control swarming robots and tissue bioengineering.
Researchers from INRA, CEA-INAC, and their partners have studied the effects of oral exposure to titanium dioxide, an additive in common foodstuffs (E171), including sweets. They provide the first evidence in animals that E171 penetrates the intestinal wall, thus entering the organism, and can create immune system disorders and induce pre-cancerous lesions in the colon.
Bacteriorhodopsin is a protein that transports protons through cell membranes—an essential function of biological systems. An international consortium involving IBS has "filmed" this transfer of protons.
The deficit in lithium observed in the early universe is not explained by the poor understanding of a nuclear reaction involving beryllium-7.
A team of researchers from CEA-BIG has identified protein CLIMP-63 as the missing link between triadin and microtubules, two molecular actors in muscular contraction. This discovery paves the way toward a better understanding of certain severe cardiac pathologies and certain myopathies.
Although the annual carbon footprint seems to be driven by temperature at the global scale, water availability appears to be the dominant factor at the local scale. A study in which LSCE researchers participated sheds new light on this paradox.
CEA and the Cyclopharma Laboratories, in partnership with company Orphachem and University Francois Rabelais in Tours, signed an exclusive license agreement for a new radiotracer for the early diagnosis of Parkinson's disease by PET scan. Phase I trials are underway.
Based on analysis of several thousands of images of Saturn's moons produced by the Cassini spacecraft (NASA/ESA) a research team was able to provide the first quantification of minuscule fluctuations in the gravitational field of this planet. These extremely fine results should allow for a better understanding of the internal structure of Saturn.

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.
