The DRF at the CEA assemble approximately 6,000 scientists since January 2016.
A theoretical physicist at the IPhT and his partners at the EPFL (Switzerland) and MIT (USA) have just revealed a temporal form of quantum entanglement. For the first time, this has allowed them to demonstrate a very strong entanglement between a photon and a phonon, in a diamond crystal at room temperature. Their experiment makes it possible to probe the coherence of single phonons on very short time scales, which opens the door to the search for materials for ultrafast quantum technologies.
A study involving the CEA-Joliot has revealed the mechanism by which certain depressive states are linked to an imbalance in gut microbiota. The endocannabinoid system makes the connecting link.
According to a collaboration involving the LSCE (CEA-CNRS-UVSQ), chlordecone has reappeared massively in the French West Indies since the end of the 1990s - when the use of glyphosate was introduced - years after it was banned.
Researchers from the CEA-Jacob and Claude Bernard University have identified a new radiosensitivity signature in patients with severe side effects following radiotherapy.
A collaboration between the LSCE (CEA-CNRS-UVSQ), the INRAE and Brazilian and Uruguayan universities established a first map of radioactive cesium deposits, following the nuclear tests of the 1960s. This map is a reference for sciences, which will allow the of soil erosion and redistribution in South America.
Researchers at the CEA-Irig have introduced a new catalysis tool for green chemistry, by creating crystalline artificial enzymes whose solid form increases stability and allows more reaction cycles under harsher conditions.

The PMIP (Paleoclimate Modelling Intercomparison Project) collaboration publishes the first results of its 4th "phase", for the study of the climates of the Middle Holocene (6,000 years ago) and the last interglacial (127,000 years ago). These periods are characterized by a greater than average seasonality in the northern hemisphere, which increases the amplitude of the seasonal cycle of boreal temperatures and strengthens the monsoons in the north.
Nearly 200 scientists from an international collaboration including CEA-Irfu have been involved in collecting, processing and assembling images of half of the sky to prepare the DESI observations from 2021 to 2026. Objective: To unveil the mystery of dark energy!
CEA-Irig researchers are identifying a catalyst to produce methane directly from CO2.

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.
