New paper from Ikeda et al. on the biogenesis of chitin bristles in the annelid #Platynereis with nice #vEM reconstructions and a chitin synthase knockout.
Bristles are formed in a process of biological 3D printing. @biology

Beautiful new study by Michael Bok, Macali & Garm on the high-resolution eyes of the enigmatic alciopid annelids, from Ponza island.
"Our results show that the eyes of alciopids possess the anatomical, morphological, and physiological properties requisite for high resolution tasks and object vision"

We have now published a new and massively extended/reworked preprint of the whole-body #Platynereis larval #connectome with over 50 figures

https://www.biorxiv.org/content/10.1101/2024.03.17.585258v1

All the analyses, plots and figures should be reproducible in #rstats with the code provided:
