Beautiful beasts (2): Thanks Ian for allowing us to help a little to help you figuring out how B-cells help T-cells. What a spectacular cover coloured by #micronaut Martin Oeggerli.

What a way to start the week. Quick morning run at Les Embiez for the #EMBO /#ParaFRAP workshop Host-Parasite Interactions, where parasites truly rule.

Beautiful beasts: excited to see our first volume electron microscopy study on malaria parasites published: advanced.onlinelibrary.wiley.com/doi/10.1002/... revealing new insights into Plasmodium ookinete development. Thanks for great EMBL-Umea-Heidelberg collaboration.

Nice cover @molmicrounihoh.bsky.social features Blastocrithidia nonstop, a trypanosomatid parasite with a non‐canonical genetic code. Associated paper by Slava Yurchenko, Julius Lukes and colleagues describes its genetic transformation: onlinelibrary.wiley.com/doi/10.1111/...

Congrats Dr Annika Binder for a fantastic thesis and defense on microtubule binding proteins of #malaria #parasites exactly 25 years after I got my Dr for something with #actin and poxviruses and almost failed a question on, well, microtubule binding proteins.

Gametes and sporozoites: Happy to see our paper probing the importance of #microtubule inner proteins in #Plasmodium published in final form @pnas.org - Sporozoites can do without MIPs but gametes cannot. www.pnas.org/doi/10.1073/...

End of year fireworks: the cover showing fully formed Plasmodium sporozoites in an oocyst by expansion microscopy accompanies our review on the functions of circumsporozoite protein; blue: anti-CSP antibody, magenta: DNA. Congrats Kevin and Maren for the beautiful image.
