In two weeks, our #qbio #Master students learned to build, from drawing to full realization, their own : confocal FCS, TIRF microscope, and optical tweezers setup ! This is hand-on #microscopy !
Interested ? Join the qbio master next year at the Montpellier University !

Excited to share our new preprint on Myxococcus xanthus!
We show that two distinct motility motors can propel the same bacterial cell simultaneously, and that this dual propulsion is tunable by environmental calcium. 🧵 1/6

When its meal turns toxic, the tiny worm #CElegans shuts down digestion thanks to a single protein that links its “taste” neurons to the gut.
Gut feeling
C. elegans uses a protein located in specific neurons to detect toxic food and shut down the digestive system.
