Until now, it has been assumed that the oxygenation of the oceans over geological timescales has mainly been driven by atmospheric oxygen levels. However, a new study published in Nature June 27 2022   suggests otherwise. Work by scientists at the Biogeosciences Laboratory (CNRS/UBFC), together with their colleagues at the University of California's Department of Earth and Planetary Sciences, shows that the movement of tectonic plates has probably contributed to ocean oxygenation.

Ultrasound is transforming the field of neuroimaging, thanks to technological advances made over the last decade by the Physics for Medicine laboratory (Inserm, ESPCI Paris - PSL, CNRS). The introduction of functional ultrasound imaging (fUS) in 2009 provided neuroscientists with a unique technology - portable, easy to use, and reasonably priced - to visualize brain activity with high sensitivity. In 2015, another method, called ultrasound localization microscopy (ULM), produced novel images of the cerebral vascular network, revealing blood vessels just a few micrometers in diameter.

Chromosomes are fluid - almost liquid - outside their division phases. This discovery was made possible thanks to the direct mechanical manipulation, for the very first time, of chromosomes in the nucleus of living cells.

Constructing a tiny robot from DNA and using it to study cell processes invisible to the naked eye... You would be forgiven for thinking it is science fiction, but it is in fact the subject of serious research by scientists from Inserm, CNRS and Université de Montpellier at the Structural Biology Center in Montpellier
