The DRF at the CEA assemble approximately 6,000 scientists since January 2016.
A team from the Iramis (CEA-CNRS) has shown that aluminosilicate nanotubes (imogolites) have an interesting potential for photocatalysis. These light-activated semiconductors could be functionalized to depollute water, in an environmentally friendly way.
In collaboration with the IECB in Bordeaux, a team from the CEA-Joliot has developed a molecule consisting of a hybrid of a peptide and an artificial polymer. This molecule is capable of inhibiting the action of a protein involved in cancers.
As part of an international collaboration, BIAM researchers have successfully produced 3D-printed microswimmers that can be guided by magnetic fields. Ultimately, these devices could be used within the human body for therapeutic purposes.
As part of a European collaboration, researchers at the CEA-Jacob have demonstrated that exposure to aggregates of α-synuclein proteins could reduce the support capacity of the brain’s immune cells, the astrocytes.
A collaboration involving the CEA-IRFM, the European consortium EUROfusion, Iter and American partners has shown that it is possible to protect successfully the internal structures of a fusion reactor against damage caused by very energetic electrons that escape the fusion plasma following a major instability.
A collaboration involving the CEA-Jacob is lifting the veil on a mystery surrounding certain bacterial viruses: the substitution in their DNA of adenine by another base, aminoadenine.
According to a study involving scientists from the University of Oklahoma (USA), INRAE and the LSCE (CEA-CNRS-UVSQ), the Brazilian Amazon rainforest has released more carbon than it has absorbed over the last ten years. The cause: the degradation of the forest due to human activities and climate change.
Researchers from the CEA-Iramis and the Laboratoire d’Optique Appliquée (ENSTA/X/CNRS) have succeeded for the first time in efficiently accelerating electrons to relativistic energies using a radially polarized laser.
Researchers at the Biam have unveiled one of the mechanisms involved in the responses of plants to variations in their environment. This work could help improve their capacity to adapt to climate change.
By studying the oscillation modes of 91 stars of all ages observed by NASA's Kepler space observatory, an international collaboration including CEA-Irfu has confirmed that "old" stars spin faster than previously accepted theories of magnetic braking predict. This discovery will now make it possible to date stars more accurately!

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.
