Annual killifish continue to surprise us: they make neutrophils before almost every other cell type, even before gastrulation. Neutrophils usually arise from the lateral plate mesoderm (forming in cyan), but in killifish they are already patrolling around the embryo in gold. tinyurl.com/killiphil

Scatter plot showing that Fast & Fair peer review reached first decision with reviews much faster than conventional peer review: mean 5.5 versus 37.7 working days. Most Fast & Fair manuscripts met the 7-working-day target, while conventional manuscripts were slower and more variable, up to 116 working days.

cover image yeeeeeeeeehawwwww #flourescentfriday check out our work in the most recent issue of @jcellsci.bsky.social !
Cover: Skin-resident macrophages (white) migrate towards a scratch wound (centre) in a zebrafish skin explant. To reach the wound margin, migrating macrophages must navigate through a dense network of epithelial cells, which are visualised using a reporter for epithelial junctions (α-catenin-Citrine, magenta). Live-cell imaging and chemical perturbations demonstrate that skin macrophages require microtubules to efficiently respond to tissue damage and navigate epithelial obstacles. See article by E. Peterman et al. (jcs264101).
