Looking forward to the KPC Mini-Symposium tomorrow — a great event for all plant scientists in the Kiel area! Speakers are: Hanin Alzubaidy, @lies-nerd.bsky.social and @molecularmax.bsky.social . Don’t miss these exciting talks and discussions!

Sudden complexity just 65 million years ago discovered by team around @jandevries.bsky.social by analysis of the green alga Coleochaete, an ancestor and an intriguing group, which has evolved elaborate disc-shaped bodies. The team reports about it in Current Biology www.cell.com/current-biol...

Phylogenomics unveil a recent origin of morphological complexity in Coleochaetophyceae

Bierenbroodspot et al. use phylogenomic analyses to study Coleochaetophyceae, phragmoplastophytic streptophyte algae that are well-known for their complex bodies. They trace that the famous discoidal ...

Excited to share our new preprint on giant virus infection in brown algae: Latent endogenous viral elements drive active infection and inheritance in a multicellular host doi.org/10.1101/2025...

Latent endogenous viral elements drive active infection and inheritance in a multicellular host

Endogenous viral elements (EVEs) inserted in host genomes are often regarded as inert relics of past infections. Whether they can retain infective potential and contribute to active viral cycles has r...

Even though sea stars were critically underrepresented, I had a blast at #ITRS2025 in Brest! 🌊🌡️⭐ First conference, first Bluesky post and somehow, I now have a soft spot for kelp.🌱 Shoutout to @lies-nerd.bsky.social , @frankmelzner.bsky.social , Mark Lenz, and all the lovely people I got to meet!

Had too much fun at #ITRS2025 to be active online, so Hi from the early train leaving Brest! It was an absolute pleasure to see so many colleagues, present novel results and represent team @geomarkiel.bsky.social with @frankmelzner.bsky.social @katjasee.bsky.social Looking forward to next time!

Still 5 hours left to meet us and various marine critters on board if RV Alkor & the Kiel Outdoor Benthocosms with an experiment on carbon storage potential of brown algae with @lies-nerd.bsky.social @geomarkiel.bsky.social #FUBLUC - and the sun is out now!

A study confirms what we have long argued: the spectacular Atlantic 'cold blob' is the result of a slowing of the Atlantic overturning circulation #AMOC, which transports warm waters into that region. That's the only part of Earth that resisted #globalwarming. 🌊 www.sciencedaily.com/releases/202...

#PhycologyFriday, from one of my favourite spots, from the wave exposed shores of northern Norway - with a mosaic of Laminaria digitata and Alaria esculenta, with some Fucus serratus, Palmaria palmata and other macroalga in between.

Spent the day at the @montereybayaquarium.org and was blown away by the massive exhibits, especially the giant #kelp cathedral 😍 Inspiring to see marine sci-comm done expertly, and I loved the hands-on science for the little ones! My lesson of the day: Fucus distichus grows also in the Pacific?!
