The DRF at the CEA assemble approximately 6,000 scientists since January 2016.
A collaboration involving Iramis and the Institut Joliot has revealed the spontaneous aggregation into amyloid fibers of a bacterial protein called Hfq and non-coding RNA strands. Furthermore, the collaborators demonstrated the ability of these fibers to penetrate a lipid membrane. This study paves the way for a better understanding of bacterial communication in addition to new approaches in antibiotic development.
After 40 years of research, BIG researchers and their partners have uncovered the cause of tubulin detyrosination. The surprise: it is not one enzyme, but two that are capable of modifying this essential component of the cell skeleton.
Should countries reduce their greenhouse gas emissions to meet their December 2015 pledges at COP21, global temperatures would expected to rise by about 3°C by 2050 with respect to pre-industrial climate. For the first time, an international team of LSCE researchers has studied the impact of such a scenario on the air quality in Europe in 2050. Their results show that current efforts to reduce European anthropogenic emission reductions would probably be annihilated.
Using a variety of sensors, physicists around the world examined the region from which a gravitational wave originated. This wave was detected on August 17, 2017 by the Ligo-Virgo facilities, in the search for other messengers from the universe. Created from the fusion of two neutron stars, this wave was accompanied by a burst in gamma rays as well as visible light emission, which was detected in particular by the Integral satellite and the VLT, with a major role played by the Irfu. Regarding neutrinos, the researchers analyzed their data without finding any candidates.
“Magnetic skyrmions” are currently emerging as promising nanoscale bits in spintronics, e.g. for dense, energy-efficient information storage or high-performance logical operations. Researchers from the Inac and the Institut Néel in Grenoble have managed to create and erase microscale skyrmions using an electric field.
Theranexus receives US patent protection for its drug candidate, THN102. In the line of sight: treating the symptoms of narcolepsy and Parkinson’s disease.
A team from the IRFM performed digital 3D simulations of the turbulence of fusion plasma in a geometry identical to that of Iter, particularly in terms of the floor of the tokamak (divertor). These studies make it possible to consider ways to control the thermal flows that are received by the most exposed components.
Fifteen musical instruments from ancient Egypt were dated by measuring their carbon-14 levels in the Carbon-14 Measurement Laboratory associated with the LSCE (Saclay). They will be exhibited at the Louvre-Lens museums until January 15, 2018, among four hundred objects that bring back to life more than three thousand years of music from the great ancient civilizations (Egypt, the Orient, Rome, Greece).
An international collaboration has published a synopsis of two climatic episodes during which the Earth was covered in ice and snow. This report takes stock of more than 35 years of scientific questioning regarding the functioning of a “snowball” Earth.
Researchers from the Biam have discovered one of the "lubricants" of the complex gears involved in photosynthesis.

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.
