Can a living organism be obliged to take something other than its regular route for the synthesis of the molecules it needs to live and multiply? A team from the François Jacob Institute of Biology did just that, getting bacteria to assimilate CO2 in a new way.
Le laboratoire de l‘Iramis spécialisé dans les archéomatériaux se lance dans une nouvelle aventure : la restauration et la protection des objets métalliques du patrimoine. Comment partager l’expérience acquise pour étudier le stockage des déchets nucléaires avec les restaurateurs, experts eux aussi de la corrosion sur le long terme ?
Thanks to the ALMA European interferometer in Chile, an international team involving IRFU has detected ionized CH+ molecules in distant galaxies for the first time. Their observations reveal the unsuspected existence of large turbulent reservoirs of gas surrounding these young galaxies. The findings explain the persistently high star formation rate observed in galaxies known as "starburst galaxies".
En France, le CEA et le CNRS ont joué un rôle de premier plan dans la conception et la construction de l’accélérateur supraconducteur à électrons X FEL, au cœur de cette nouvelle infrastructure de recherche internationale inauguré à Hambourg (Allemagne) le 1er septembre 2017
Through the study of model systems, physicists from IRAMIS are gaining a deeper understanding of the mechanisms involved in the irradiation of a crystalline surface with "swift" ions. Ion beams can be produced by small accelerators and make it possible to shape surfaces on the atomic scale, including high-quality incisions or bends in a monoatomic layer of molybdenum disulfide (MoS2) or graphene.
For the first time, IRAMIS researchers have isolated complex ion pairs in the gas phase and were able to characterize them using UV and infrared spectroscopy. This original experimental approach will deepen the scientists' understanding of extremely diverse physicochemical processes in media as varied as biological cells and batteries.
Several decades after its discovery, dark matter remains enigmatic. Researchers from IRFU have tested three models of dark matter in which the formation of large structures was modeled using supercomputing. The reconstruction of large structures from observations of quasar spectra favors the hypothesis of a standard "cold" dark matter and sets some of the strongest constraints on these invisible masses.
Physicists from IRFU have announced that no "big brother" of the Higgs boson has been detected at the ATLAS experiment at CERN's LHC. Their results rely on new analyzes with higher sensitivity.
A European collaboration involving IRAMIS has described the fabrication of nanoporous graphene sheets that are both robust and easy to handle. The process, which can be used for large area fabrication, uses a copper/graphene/polymer 'sandwich' exposed to heavy swift-ion beam irradiation. It paves the way for numerous applications, including filtration for DNA sequencing and desalination of seawater.
A team from IRFU has reached a first milestone in the development of a detector for brain imaging which, scientists hope, will allow the measure of spatial resolution in positron emission tomography (PET) scans at the MRI level (mm3). The scientists have recently achieved the ultra-purification of a liquid similar the candidate for detection.
