  • Marine worms possess camera-type eyes. Here they show that the growth of marine annelid eyes depends on a stem cell system reminiscent of vertebrate eyes. Moreover, eye development seems to be tuned by a light-sensitive opsin known from vertebrate vision.

  • Bristleworms possess dedicated cells that can synthesize highly stereotypical bristles with sub-micrometric precision. Here, Ikeda and colleagues shed light on the underlying dynamics of cellular protrusions, revealing an extension-disassembly cycle that resembles a 3D printer.

  • Genomic and molecular analyses of Clunio marinus timing strains suggest that modulation of alternative splicing of Ca2+/calmodulin-dependent kinase II represents a mechanism for evolutionary adaptation of circadian timing.

  • Reproduction in numerous marine organisms is timed to specific moon phases, but the mechanisms for sensing moon phases are incompletely understood. Here the authors report that an ancient, light-sensitive protein L-Cryptochrome in a marine bristle worm can discriminate between sun- and moonlight, enabling the animals to properly decode moon phases.

  • Regenerative capacity varies between species, with some animals showing robust whole-animal regeneration after amputation. Here they use time-resolved scRNA-seq and mosaic transgenesis to delineate how stem cells re-emerge after amputation in an annelid worm, and reveal unexpected parallels to vertebrate regeneration models.

  • The beetle Tribolium castaneum is a commonly used laboratory model, combining the ease of systematic RNAi experiments like those in Caenorhabditis elegans, with biology that is more representative of most insects than Drosophila melanogaster. A large consortium has sequenced and analysed the genome of the red flour beetle, creating a resource for biologists everywhere.

  • Recent work suggests that microRNAs might have been important in the evolution of complexity in multicellular animals. Here it is shown that the most ancient known microRNA, miR–100, was initially active in neurosecretory cells around the mouth. Other highly conserved varieties were first present in specific tissues and organ systems. Thus, microRNA expression was initially restricted to an ancient set of ancient animal cell types and tissues.
