The DRF at the CEA assemble approximately 6,000 scientists since January 2016.
An interactive video has made it possible to reconstruct the trajectories of 1,400 galaxies, including the Milky Way, over distances reaching up to 100 million light years.
When exposed to low-energy ultraviolet radiation, the extremities of chromosomes (or telomeres) can produce radicals that cause oxidative damage. A detailed study using time-resolved spectroscopy conducted at the Iramis reveals the mechanisms associated with these processes.
A molecule proves to reduce the sensitivity of cells to many particularly aggressive toxins and viruses. Scientists from the CEA’s Institut Frédéric-Joliot have deciphered this protection mechanism.
A radio frequency transmission method patented at the Institut Frédéric-Joliot now makes it possible to remove artifacts present on 3-Tesla images of large organs.
Les propriétés magnétiques et électriques des jonctions tunnel magnétiques ont pu être améliorées significativement en insérant des couches de métal réfractaire (tungstène) dans les empilements. Cette avancée ouvre de belles perspectives aux mémoires magnétiques MRAM composées de telles jonctions et qui rentrent en production de volume.
The observation by a scientific collective of a thousand far away “elliptical” galaxies is shaking up our knowledge of galaxies. How can they be rich in gas without producing any stars?
Plant stomata open or close in response to their needs, in addition to water stress or pathogen attack. A team from the Biam and its partners have demonstrated the role of the protein AQP in stomatal closure movements.
The African exodus of our species, Homo sapiens, has just been pushed back by at least 60,000 years in comparison to what we previously thought. This now places the date at around 177,000 - 194,000 years ago. This international study, which includes the LSCE, is based on the dating of the oldest modern human fossil found outside of Africa (Israel).
A team from the BIG Institute has just demonstrated that uranium is not necessarily toxic to plants.
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.
