The DRF at the CEA assemble approximately 6,000 scientists since January 2016.
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!
Researchers from the LSCE/LMC14 (CEA-CNRS-UVSQ) and the Institut de recherche de Chimie Paris (CNRS-Chimie ParisTech-C2RMF) have settled a long-standing controversy: The wax bust of Flora kept in the Bode Museum in Berlin is later than the Renaissance. To achieve this, they conducted a rigorous investigation, combining chemical analyses and carbon-14 measurements, and succeeded in meeting the challenge of dating an extract of marine animal, spermaceti.
A CEA-Joliot team is developing with the AP-HP a mass spectrometry diagnostic test for COVID-19 that would also make it possible to assess the patient’s viral load. Their aim is to make the method more sensitive and more compatible with hospital equipment.
Thanks to an original experimental setup, scientists from CEA-IRIG clarified for the first time how the response of a spin current to the perturbation brought by a ferromagnetic material depends on the orientation of the majority spin with respect to the magnetization of the material. A fundamental point for understanding spin transport in spintronic components!
An international collaboration of climate researchers including the LSCE (CEA-CNRS-UVSQ) is using a model of the Earth System to determine the different regional contributions to global warming, as well as the individual factors that modify and amplify it, such as CO2 emissions, or, on the opposite, by temporarily attenuating it, such as aerosols. This model represents a valuable tool for implementing a responsible climate policy.
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.
