It's finally here! Great start of the summer. We got our latest preprint from @chemamd.bsky.social in @qmulsbbs.bsky.social @qmulse.bsky.social, showing evidence of developmental system drift in the specification of dorsoventral (belly vs back) axis in annelids 🪱🪱🪱
#DevBio #EvoDevo
Image shows larvae of four different species of marine annelid worms, stained for muscle (magenta) and cilia (yellow). All with lateral views, with the mouth towards the left, and the future head pointing up. Images are to scale.

We enjoyed sharing our passion for science at UCL Illuminated, showcasing how morphology & DNA are used to study evolution! Thanks to everyone who stopped by; @nateomics.bsky.social & I enjoyed discussing topics from dinosaurs, landmarking & Procrustes to Bayesian methods & genomes! 🦴🦖🧬💻 #UCL200
Sandy talking about the workflow for timetree inference with geometric morphometrics data at UCL Illuminated. The table shows the items we used as part of our scientific activity for this outreach event at UCL Illuminated: various skull casts from different species and an activity that uses dinosaur species for familiarising with landmarking and the usage of morphology for the study of evolution. Nath & Sandy ready for talking about the usage of morphology and DNA for the study of evolution during UCL Illuminated as part of their outreach scientific activity -- we were there from 17.30h to 22.00h!

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

Kosakyan et al. sequenced mitogenomes of species from the two main lineages of the Gastrotricha; they found stable mitogenomes in the mostly freshwater Chaetonotida, but a dynamic pattern in the the marine Macrodasyida.

Bees 🐝
This art features 100 bees of various colors and shapes. These bees are designed in a cartoonish style, based on real species. The common name or species is written below the animals. Some bees are moving leaves, scraping plant hair, or sticking out their tongues. Some male bees have hairy faces and unusually shaped legs. There are also baby bees that have just hatched from their petal nests. Cute and colorful atmosphere. There are over 20,000 species of bees, so I only depicted a very small fraction of them!

Wnt/β-catenin signaling promotes posterior axial regeneration in non-regenerative tissue of the annelid C. teleta, enabling the prospect of increasing regeneration ability in regeneration-deficient tissues

By Lauren Kunselman, Elaine Seaver

tinyurl.com/2bxpecek
Comparison of regeneration responses to Wnt signaling perturbation in different species. In both panels, the cladogram indicates phylogenetic relationships. P. fluviatilis and D. lacteum are most closely related to each other and share the same response to canonical Wnt activation and inhibition, so they are represented by one graphic. A(+)/P(+) = anterior and posterior regeneration ability present. A(±)/P(+) = anterior regeneration ability present if cut in anterior 2/3 of body, posterior regeneration ability present. A(−)/P(+) = no anterior regeneration ability, posterior regeneration ability present. Light blue color represents regenerated tissue. (a) Increasing canonical Wnt signaling after amputation results in ectopic posterior axis formation in all species. (b) Decreasing canonical Wnt signaling after amputation results in ectopic head formation in H. miamia and S. mediterranea and rescued anterior regeneration ability in P. fluviatilis and D. lacteum, whereas in C. teleta, no ectopic heads form and anterior regeneration is not rescued.

The red-chested sea cucumber, Trachythyone insolens, from Cape Town, South Africa 🇿🇦.
Holothurians (sea cucumbers) are primarily deposit or suspension feeders that use specialized, mucus-covered oral tentacles to trap food particles, such as organic detritus, from the seabed or water column.

Look closely at the surface of the sea cucumber…

There’s a strange little creature hiding there!
This scale worm changes its coloring to match its sea cucumber host.

You’d never notice it unless it moves. Such amazing camouflage! ✨️
