We all learnt from each other and it was real pleasure working together to understand GAPMs in plasmodium.

New preprint! Really excited to share our spatial proteomic study on Plasmodium falciparum schizonts . We used hyperLOPIT to map thousands of proteins—from apical invasion organelles to the infected red blood cell surface.

“The idea that taking walks, reading things unrelated to your research, and hanging out with strangers in a campus pub should be considered part of the serious process of thinking, but might well meet with skepticism in practice.” www.pnas.org/doi/10.1073/...

📸 No one follows more etiquette rules than the Royal Family—but notice how King Charles didn’t make any smart-ass or demeaning comments about Zelensky’s attire today. Why? Because respect isn’t about clothes—it’s about character. And that’s something money can’t buy.

The Nikon AX-NSPARC demo is gearing up at the @ncis-marseille.bsky.social! Starting for #FluorescenceFriday with a large field-of-view confocal #cellfie of COS cells labeled for actin ⚫ endoplasmic reticulum 🟡 mitochondria 🔴 and nucleus 🔵. Fluorescence microscopy is also nice in inverted colors 🌈🧪
A group of four COS cells - one seems to pull the other up like we all should do
