Algal symbionts go through a lot for their acoel host: ingested, stripped of cell wall and flagella, displaced to all tissues, both intra- and extracellular. Animal grows, gets nutrients and some stress responses.

Absence of conserved immune signalling pathways and increased pathogen susceptibility associated to photosymbiosis in acoels - BMC Biology Background Host immunity plays an important role in coral symbiosis with dinoflagellates. Photosymbiosis (the association between hosts and photosynthetic endosymbionts) has evolved multiple times wit...

First paper of my PhD published 🎉

doi.org/10.1186/s129...

It's about immunity in acoel worms and its link to photosymbiosis. There's evolution and immune gene expression, but also mortality, dysbiosis, and host responses upon pathogen exposure.

Multiple losses of ecdysone receptor genes in nematodes: an alternative evolutionary scenario of molting regulation Molting is a hallmark feature of ecdysozoans, including arthropods, tardigrades, and nematodes.

Found some serpulid worm tubes! 🪱 Fresh ones are bright white with calcium carbonate, while older, likely empty ones turn black from magnetite deposits. Worms are endlessly fascinating! 🖤✨ #WormWednesday with @mariheilertsen.bsky.social @cdeepsea.bsky.social

The bridge of the research vessel seen from the front deck, darkness only broken by the lights of the ship. The ship is covered by ice.

Scientist looking out over the ice from the front of the ship.

The side of the ship breaking through a solid slab of ice.

We are currently breaking ice with the RV Kronprins Haakon in the polar darkness, trying to get to our sampling station 🌌🧊❄️ Turns out that the route through the ice is rarely a straight line! @cdeepsea.bsky.social @rimskaya.bsky.social

Abyssal sea spider in the Arctic! Its small body contrasts with its long legs, which house the gut and reproductive organs. Likely a male—those slender ovigers for cleaning and egg care are a giveaway. But why are the basal leg segments swollen? 🤔 And that proboscis—huge! What’s it feeding on?

Wood on a research vessel? 🌊 Yep! @mariheilertsen.bsky.social has been collecting it—not for a lumberjack mission, but to study abyssal wood-borers (Xyloredo), also called shipworms. 🛳🪱 These bivalves, cousins of oysters and mussels, use their shells to carve tunnels into wood. 🐚🪵

#wormwednesday for real! 24 h!

After sampling and sorting during the night i do extraction of worms and hopefully also RNA 🤞🏻

Heading north, where the night deepens. 🌌

Our goal: catch as many deep-sea creatures as possible for scientific research. 🪱🐙🦑🪼🦀

We’re a small but determined deep-sea biology team 🐟🌊 aboard the RV Kronprins Haakon (Norsk Polarinstitutt, IMR, UiB) together with @mariheilertsen.bsky.social

Wooow! Check out the preprint: www.biorxiv.org/content/10.1... i was extremly lucky to listen to the talk of Casey Dunn in person. @ FSU Jena. Physalia does not migrate on the long distances as i thought before! More in preprint.

Shumpei 👏! What about other ecdysozoans? 🤔
