The DRF at the CEA assemble approximately 6,000 scientists since January 2016.
Root-knot nematodes are devastating species to global agriculture; those that reproduce asexually are especially thriving. Researchers from CEA-Genoscope and their partners proposed a hypothesis to explain this extraordinary success.
Researchers from INAC have modeled spin wave sources using base metals. They showed that the presence of the interaction called Dzyaloshinskii-Moriya in these materials, combined with a judicious choice of system geometry, allows for the obtaining of a spin wave source that is unidirectional.
In 2007, the Von-Karman-Sodium (VKS) experiment in Cadarache showed that a macroscopic magnetic field can emerge spontaneously within a turbulent conductive liquid (by “dynamo” effect). New high-definition simulations of VKS highlight the influence of liquid resistivity and the nature of the turbines that agitate the liquid. These recent simulations contribute to a better understanding of the magnetic field of stars and certain planets.
Researchers from IBS have patented a method of biological welding based on their study of pneumococcal pili.
Scientists from INAC and Institut Néel have developed a new technique to precisely map the position of semiconductor quantum dots integrated in a photonic structure.
In March 2017, following a series of successful tests, IRFU has delivered its in-kind contributions to the European Spallation Source (ESS) project in Lund, Sweden: an optical diagnostic and an emittance-meter to control the purity and vergence of the proton beam (under the responsibility of IRFU). Under construction since 2013, the spallation source is expected to enter service in 2019. It will be nearly one hundred times more intense than current sources.
Climate scientists have shown that weather anomalies can exert a significant influence on a country's CO2 emissions and, to a lesser extent, on global emissions.
Physicists from INAC have provided evidence for previously unseen quantum phase transitions in a superconducting ferromagnetic compound (UCoGe) under the influence of an external magnetic field.
The PILOT experiment to observe interstellar matter and stars in formation was launched in Australia on April 17, 2017, under a stratospheric balloon. PILOT will observe the polarization of infrared light emitted by dust particles using its detectors and reading electronics provided by IRFU.
How to explain the cohesion between photosynthetic membranes, which, stacked on top of one another, turn one square meter of leaves into a photosynthetic surface area as large as an entire rugby stadium? Scientists from CEA-BIG and ILL shared their insights on the matter.

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.
