Even more excited — our paper is featured on the cover of Science Advances!
Huge thanks to @alexandrejan.bsky.social who took this incredible photo of a ctenophore (aka comb jelly) and the editors.

Version of record of our ctenophore nerve-net connectome paper.
Evolution of monoamine reception and its role in cellular contractility.
How do #sponges coordinate their bodies despite lacking neurons and true muscles?
We show that sponges use monoamines to control water flow in their canals — reminiscent of how adrenaline regulates blood vessels.

A scanning electron microscopy image of the ragworm Platynereis dumerilii. Photo credit: John Kirwan and Ola Gustafsson.
The ragworm Platynereis dumerilii does its mating dance in near total darkness, yet the adults have huge eyes with long light-sensing cells. Kirwan &co show that these cells help them see a tiny bit better helping them find mates to dance with in the dark

Screenshot of the PDF of the first page of the Research Article, Dancing in the dark: the annelid Platynereis dumerilii is re-envisaged for its climactic final night, by John D. Kirwan, Emelie A. Brodrick, Jacob Bartholin, Morten Bartholin, Julius Friis Petersen, Cameron Hird, and Anders L. Garm. The publishing information states: © 2026. Published by The Company of Biologists | Journal of Experimental Biology (2026) 229, jeb251047. doi:10.1242/jeb.251047. The first sentence of the Abstract states: 'When sexually mature, the marine annelid Platynereis dumerilii emerges at night from its tube and swims to the surface in search of a mate'.

To turn spatial data into a 3D object, check our protocol (open source, napari plug-in). @guignardlab.bsky.social @adrianobolondi.bsky.social @ibdm.bsky.social
For example, if you have spatial RNA-seq as sections, you can align them automatically to analyse directly in 3D.
