🧠 The Lipid #Brain Atlas is out now! If you think #lipids are boring and membranes are all the same, prepare to be surprised. Led by @lucafusarbassini.bsky.social with Giovanni D'Angelo's lab, we mapped membrane lipids in the mouse brain at high resolution.

I am thrilled to share our latest story led by the incredibly talented Brooke D’Arcy and Camila Musso. We discover a rich world of local gene expression in radial glia, essential neural and glial precursors, and develop a new method for sub-cellular mRNA manipulation. www.biorxiv.org/content/10.1...
