In two articles published in PLoS ONE, researchers at NeuroSpin show that diffusion MRI can monitor astrocyte activity in the brain in a non-invasive way, allowing a better understanding of its involvement in the glymphatic system and in functional MRI.
SPI researchers (Marcoule) used proteomics to identify signature peptides of the SARS-CoV-2 virus expressed in vitro. A "short list" of 14 identified and characterized peptides allows to consider developments in targeted mass spectrometry, making this direct and rapid large-scale approach, implantable in hospitals, a potential tool of choice in the detection of the virus responsible for Covid-19.
Using public MRI data sets from the knee and brain, researchers from NeuroSpin and Cosmostat (CEA-Irfu) have written a consistent benchmark of several deep neural networks used for image reconstruction with significantly reduced acquisition time.
An opinion article, published in Environmental Microbiology, and written by an international consortium initiated by three researchers of Joliot Institute, proposes an original way of research on Covid-19 through the identification by sequencing of attenuated variants of the SARS-CoV-2 virus in populations at risk with little or no symptoms.
Researchers from the SCBM in collaboration with teams from IRAMIS, AstraZeneca and the Karolinska Institutet have developed a second marking method based on the dynamic exchange of carbon dioxide, this time without catalysis, by "simple" thermal heating. Ideal for organic molecules of therapeutic interest, the method is described in tAngewandte Chemie.
A team from SCBM, in collaboration with researchers from I2BC, SHFJ and IRAMIS, has synthesized new neutral macrocycles called bambusurils (BUs). These BUs can be functionalized by “click chemistry” to obtain multivalent architectures decorated with 8 to 12 ligands of interest, an alternate topology which gives them remarkable supramolecular properties.
A collaboration led by I2BC researchers presents, in the Journal of Experimental Botany, a body of evidence for a dynamic association of the PTOX protein with thylakoid membranes, dependent on proton motive force.
In order to answer this question, a vast study of experimental psychology and chronobiology, directed by Virginie Van Wassenhove (NeuroSpin) was launched in collaboration with Inserm and the University of Paris-Saclay.

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.
