The DRF at the CEA assemble approximately 6,000 scientists since January 2016.
A team from the Inac has proposed a new method to measure a semiconductor quantum dot by radiofrequency reflectometry. This method, which utilizes MOS technology on silicon, can easily be extrapolated on a larger scale to produce dense quantum bit architectures.
In collaboration with the François-Jacob Institute and scientists from Germany, scientists from the Frédéric-Joliot Institute have identified a biomarker of senescence in human tissues. Their finding provides new clues on how to mitigate the effects of aging.
A team from IRAMIS has implemented a new optical microscopy technique to observe two-dimensional nanomaterials with unprecedented sensitivity and monitor their chemical functionalization in real time. Their work creates a particularly promising route for biodetection.
A collaboration led by INAC has produced GaN/InAlN quantum well nanotubes with good light emission properties in the UV range. They will be included in a polymer to obtain flexible LEDs.
An international team, including a researcher from IRFU, has discovered an elliptical galaxy with an unexpected jellyfish shape, within a galaxy cluster about one billion light-years away. The completely atypical presence of long “tails” of gas and areas of star formation could be explained by a recent merger with a companion gas-rich galaxy.
Researchers from the BIG have revealed the functions of specific RNAs that intervene during protein production. These circular molecules have more than one trick in their bag.
Researchers from the Inac have developed new approaches to UV and infrared detection using individual gallium nitride (GaN) nanowires. In particular, they produced the first nanowire photodetector using electronic transitions within the conduction band of a semiconducting heterostructure.
The Cherenkov Telescope Array (CTA) consortium brings together 1300 scientists from 32 countries. They have published their scientific aims in a document over 200 pages long. This is the result of several years of work, and includes contributions from approximately fifteen Irfu researchers involved in X-ray and gamma-ray observatories (Fermi, Integral, XMM-Newton, Hess, etc.).
A CEA research team, headed by Denis Le Bihan, has just used diffusion MRI to reveal the connection between the level of neuronal activity in regions concerned by wake-sleep states in anesthetized rats, and the degree of neuronal swelling in these regions.
To better understand the effects of therapeutic irradiation on cartilage, the structure of its main constituent, collagen, has been studied by a collaboration involving Iramis. Their analysis suggests that the stability of collagen owes nothing to its aqueous environment, but all to its remarkable triple helix structure that can exist in the absence of any solvent.

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.
