Second new preprint of the week: Postdocs Arshad Padhiar and Maria Rodgers and collaborators describe the morphology, cell content (scRNAseq), gene expression, histology of the stickleback intestine. We present a method for building #stickleback gut organoids www.biorxiv.org/content/10.6... /t

Look, people. We have superb keynotes, we are giving prizes, we are giving postdocs a megaphone to tell everyone why they should be hired. This is the meeting to be at. Sign up, join us, and have the time of your life while discussing science with people that know where the cleithrum is🐟🧪

In a new study, Prof. Anissa Kempf's team demonstrates in fruit flies that gut function is linked to feeding, sleep, and survival. Their work adds to growing evidence that the gut communicates with the brain and can influence behavior. 🧪@unibas.ch #ScienceAdvances @snsf.ch

I am happy to announce that my penultimate post-doc paper (Erik Duboue lab/X) is finally out in Science Advances. This work stems from my first cavefish experiments, examining how dark-adapted cavefish larvae respond to changes in illumination. www.science.org/doi/10.1126/...

PRIZES for Posters PRIZES for Talks PRIZES for the best 'Postdoc to PI' Talk (register, folks. This is a great opportunity to tell us why fish are awesome and why you would be a great colleague and also show pretty pictures)🧪🐟

Not every #cichlid fish needs two parents! A Cyphotilapia frontosa female produced offspring in the absence of a male, with #genome-wide heterozygosity patterns consistent with self-fertilization. Amazing work by M. Efe Uysal with W. Salzburger and A. Marks Preprint: www.biorxiv.org/content/10.6...

Hi folks, there is a high likelihood I will be recruiting 1-2 PhD students to start in Spring 2027. Trying to get the word out early; please share broadly with your networks and encourage your students to reach out early. Info can be found on my webpage. fuesslab.wp.txstate.edu/opportunities/

Exciting new #Zebrafish research from the #WeinsteinLab, led by Jong Park! “Specialized gas-exchange endothelium of the zebrafish gill” — www.biorxiv.org/content/10.6... Amazing to see red blood cells moving through the gills! Don’t forget to check out the supplemental movies ;-)

I am happy to report that the lab has its first preprint! We looked at odor perception in cavefish and found a strong attraction to ancestrally negative odors, including appetitive behavior and brain activity when smelling death! www.biorxiv.org/content/10.1...

More new work from the lab! @idrm.ox.ac.uk @oxforddpag.bsky.social Do all zebrafish regenerate their hearts equally? Also featuring the Mexican cavefish☺️ Thanks to all co-authors and especially the incredibly talented DPhil student Kostas Lekkos who drove the project. #zebrafish #heartregeneration

Ribeiro et al. studied #MHC class II variation and infection by a sexually transmitted bacterium (C34) in black-legged #kittiwakes. They found sex-specific links between MHC supertypes, bacterial load and reproduction, suggesting STIs may influence immune gene evolution: doi.org/10.1093/jeb/...

The naturalist Jane Goodall died today at 91. Hope, she argued, is not merely “passive wishful thinking” but a “crucial survival trait.” Revisit a conversation with Goodall, from 2021: nyer.cm/F55JtsS

This gorgeous being is thwaitesia argentiopunctata. Also known as the sequinned spider, mirror spider and is found in Australia. Absolutely beautiful! I am at a loss for words. #nature #arachnid #insect #mirrorspider #Australia

Excited to start being part of the Postdoc Network Münster #PNM! @uni-muenster.de as a board member! A chance to give back to the community, and to the sometimes ‘grey’, neglected minority we postdocs are 💪✨

#Behindthepaper stories: @accorsi-alice.bsky.social & @planaria1.bsky.social share how curiosity & passion driven research revealed that apple snails can regenerate full camera type eyes. @the-node.bsky.social @ucdavis.bsky.social @stowersinstitute.bsky.social #regeneration #applesnails #devbio

How do your #linguistic, #economic & #gender backgrounds impact your #scientific productivity? @tatsuya-amano.bsky.social & co reveal that being a woman, a non-native English speaker, and from a low-income country is associated with a 70% reduction in productivity @plosbiology.org 🧪 plos.io/4n3RLRQ

These days at @naturalsciences-be.bsky.social I had the chance to visit the world’s largest otolith collection! Mostly marine specimens from a project started more than 100 years ago! Amazing to be a scientist and get the chance to go behind the scenes! #fish #otolith

Back from my first #FishBase conference! It felt like a journey through the history of key databases and the exciting ones still to come! Times are changing, and so is how we understand #fish. Truly honored to have been invited to speak at this one!

What determines the human gut fungal community? @emilyvansyoc.bsky.social @erdavenport.bsky.social @symbionticism.bsky.social &co present the first #GWAS of human genetic loci that influence the abundance of gut #fungi, linking these to disease risk #mycobiome @plosbiology.org 🧪 plos.io/42bCKou

Back from one of the best conferences I’ve attended!The @embo.org Workshop on Barrier Immunity,brilliantly organized by @maurogaya.bsky.social & @immunologyking.bsky.social! Outstanding science from many, including @mucosalimmunology.bsky.social, @danmucida.bsky.social& @martinaparigi.bsky.social

In crater Lake Masoko one fish species is splitting into shallow and deep-living ecotypes occupying different light environments. New research shows their visual systems are diverging, and how colours of male eggspots have changed to maximise their visibility. doi.org/10.1093/molb...

Amazing fantastic great talks so far @embo.org Barrier ImmuniTy 🤩 what better place to learn all about B/T cells in the gut/lung/liver/bladder/brain - eeeeeverywhere!! #EMBOBarrierTissues

An extremely engaging talk on a sometimes overlooked tissue, the bladder, by Molly A. Ingersoll at #EMBO. Not only that, the study showed that 'sex matters,' and it matters a lot during infection, with strong differential responses between sexes!!! Learning so much!! #EMBOBarrierTissues

Great analogy to illustrate the question @carlanowosad.bsky.social is pursuing on her lab: how GC are form and how GC cells find their way to their specific locations #embo workshop Basel #immunalogy

Weight loss improves health but What happens to cells in the fat during weight loss? Intriguingly, immune cell numbers decrease but their activated states persist w chronic inflammatory potential. Beautiful work from neighbors @mrc-lms.bsky.social Will Scott et al www.nature.com/articles/s41...

Check out our new paper! We find cavefish colonized caves 3x and global cooling events may have influenced these events. royalsocietypublishing.org/doi/10.1098/...

When populations evolve different strategies to defend against a recently acquired parasite (e.g., tolerance, resistance), what sets of gene expression responses are conserved, or diverge? Using a vaccination experiment with #stickleback @laurenfuess.bsky.social reports some fun results...

Mexican tetras living on the surface (left) look dramatically different from populations that were washed into caves generations ago (right) – and not just on the outside. Featuring @rohner.bsky.social‬ and others. knowablemagazine.org/content/arti...

My brilliant friend, Dr. María Recuerda, presenting her work on bird pangenomes at #ESEB2025!

For a parasite fan like me, this was one of the best talks I’ve ever attended, a whole lifetime of science across scales, delivered by none other than Prof. Dieter Ebert! #ESEB2025
