A crowd of marine embryos self-assembles into a living solid Nature Physics - Marine embryos are usually studied in isolation. But when starfish embryos are in a crowd, they self-assemble into living solids with unexpected dynamics, revealing how simple...

What happens when marine embryos are crowded instead of isolated?

They become materials.

Macro photo of the head Peripatoides novaezealandicae from ventral.
You can see the “teeth” very well. And if the upload quality is enough the structure of the cuticle (better than on the mCT scan).
You can even see what I have called the “thingies on the thingies”.

Yet again the same worm. Regular photo this time. I just finished turning the background black. :)

The little “paws” are very cute, but the mouth is terrifying.

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.

Are interphylum spiralian relationships resolvable? The phyla making up the major animal clade of Spiralia have been clear since the advent of molecular phylogenetics; the relationships between these spiralian phyla have not. The lack of consensus over the relationships between these important animal phyla might be a clue implying their emergence in an explosive radiation. Focusing on the five largest spiralian phyla (Annelida, Brachiopoda, Mollusca, Nemertea and Platyhelminthes) and using two phylogenomic datasets, we have applied site-bootstrapping and taxon-jackknifing to explore this example of taxonomic instability. Analyses on the 105 possible rooted trees relating them showed that interphylum branches are very short. Preference for rooting Spiralia on Platyhelminthes is a long-branch artefact. Most analyses on the 15 unrooted trees showed a preference for the same topology but the support over other solutions was non significant. We conclude that the spiralian phyla emerged in rapid succession resulting in a difficult to resolve radiation. The deep history we infer for Spiralia has wide ranging implications for our interpretation of Cambrian fossils and for the evolution of traits such as biomineralization, segmentation and larvae. Impact Statement Analyses of two independent phylogenomic datasets suggest an explosive radiation at the origin of Spiralia, with implications for understanding the group’s evolutionary history. ### Competing Interest Statement The authors have declared no competing interest.

We encourage excellent early career scientists (i.e., PhD candidate gaining doctoral degree before 9 September or scientist with max. 8 y full-time equivalent experience in research by 9 September), who are interested in applying for a MSCA Postdoctoral Fellowship in Ecology at the University of Tromsø (UiT) to send in their application (max. 3-page CV & 2-page project plan). Deadline for application of intramural selection of candidates is 16 February. Chosen candidates will be supported by UiT to write an application for MSCA postdoctoral fellowship (deadline 9 September 2026). If granted (21-39% success rate for intramurally supported applications since 2018), the project shall start 1 May 2027. For more information about the application process and to apply see https://euraxess.ec.europa.eu/jobs/403197.

Regarding scientific background of project, we are interested in estimating the impact of ocean warming on benthic communities. For this purpose, unheated settlement panels (= control) and panels heated 1, 2, and 3 °C above ambient seawater temperature have been put out at 10 m depth in a fjord near the island of Tromsø in September 2024 (more information at Heated settlement plates (HSPl) in global experimentation: Experiences, research questions, future applications and collaborations). All panels had been photographed after 1 y of field incubation in September 2025 and more sampling is planned in 2026, to take samples for species identification ("ground truthing" of photographed individuals in collaboration with David Barnes at BAS, UK) and gene expression studies. Furthermore, there are tank facilities at UiT to measure physiological responses of organisms from unheated and heated panels. We are interested to hear about your ideas and read your research plan within the scope of the heated panels experiment.

Cool postdoc opportunity in Norway to evaluate global-change impacts on marine communities. Application info at euraxess.ec.europa.eu/jobs/403197 🌊🦑

Minneapolis community defies ICE to warn immigrants of approaching agents If there’s been a soundtrack to life in Minneapolis in recent weeks, it’s the shrieking whistles and honking horns of thousands of people following immigration agents across the city.
