Amazing to see red blood cells moving through the gills! Don’t forget to check out the supplemental movies ;-)

The Nobel Prize in medicine goes to 3 scientists for key immune system discoveries They won for their work on peripheral immune tolerance, which is one way the body helps keep the immune system from getting out of whack and attacking your own tissues..

Looking forward to our next #globalimmuno talk this Wednesday, October 8th, at 9am PST, noon EST, 4pm GMT by Dr. Mauro Gaya.

Title: “B cell memory in barrier tissues”

The evolution of cavefish odor perception shifts fish response from avoidance to approach when exposed to alarm and death odors. An animals survival is dependent on activating the correct behavioral circuit in response to a sensory stimulus. These stimuli include environmental odorants that evoke positive approach behavior and ...

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!

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

An MHC class II supertype confers resistance to a sexually transmitted bacterium in females but not in males in a genetically monogamous seabird Abstract. The major histocompatibility complex (MHC) is a gene cluster essential for pathogen recognition in jawed vertebrates. It encompasses the MHC clas

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:

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

Jane Goodall, primatologist and friend to chimpanzees, dies at 91 She used her global fame to draw attention to the plight of dwindling chimpanzee populations and, more broadly, to the perils of environmental destruction.

Beautiful mirror spider.from Australia.

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.

Scientific productivity gap based on English-language peer-reviewed papers. Shown are the maximum % differences in the number of peer-reviewed papers published by female native English speakers from a high-income country (-45%), female non-native English speakers from a high-income country (-60%), and female non-native English speakers from a lower-middle income country (-70%), compared to male native English speakers from a high-income country (red flag).

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!

Human fungi-associated variants (FAVs) associate with 9 fungal taxa and overlap protein-coding genes. A Manhattan plot shows all FAVs and their associated fungal taxa at the three significance levels (exploratory, black; genome-wide, red; study-wide, blue).

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

Lake Masoko in Southern Tanzania, also known as Lake Kisiba, is only ~40m deep and 600m in diameter. It was formed around 50,000 years ago, and is isolated from all nearby rivers and lakes. Genetic data suggest it was colonised by Astatotilapia calliptera around 10,000 years ago.

In Lake Masoko, Astatotilapia calliptera has two ecotypes. The shallow living "littoral" ecotype has yellowish males, while the deep living "benthic" ecotype has blueish males. Recently published research led by Madeleine Carruthers and colleagues shows how these fish occupy different light regimes, and have correspondingly different visual sensitivities. Males of these ecotypes have brightly coloured eggspots, used to signal their prowess. The colours of those spots have shifted to maximise their visibility to other fish of the same ecotype. Genetic data suggest these ecotypes are largely reproductively isolated, and started to separate only 1000 years ago. Photos are kindly provided by Ad Konings.

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!!

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
