Heading to the International Congress on Invertebrate Morphology in Chile? 😄
Don’t miss the talk by our PhD student Alena Kizenko on Aug 12, on how an ancient cytoskeletal gene found a new role in tunicate development 🧬 #EvoDevo #Invertebrates

Latest paper elifesciences.org/articles/107... closes an important cycle in our efforts to study regeneration: week-long recordings allow us to observe the behaviour of cells during the entire course of regeneration in a crustacean leg – bright objects in movie are fluorescent nuclei of cells. 1/6

Meet our first MSc student!

This is @noralied.bsky.social 🌟 She is in her 5th year studying natural science with teacher education at #NTNU, and for her thesis she will optimize immunohistochemical methods for detecting neurons in marine annelid brains 🧠💪

A very rare & yet-to-be-classified species of deep-water #anglerfish in its larval stage. Anyone care to lend me their sub so I can go searching for an adult lying on the seafloor at 2500m deep?😁

UCL – University College London UCL is consistently ranked as one of the top ten universities in the world (QS World University Rankings 2010-2022) and is No.2 in the UK for research power (Research Excellence Framework 2021).

We are recruiting a new PI at the FIL @imagingneuroucl.bsky.social, Associate or Full Professor. This is an amazing place to do cognitive neuroscience, in the heart of London. If you or someone you know might be interested, please pass it on. #neuroskyence

My PhD work from @hariharanlab.bsky.social is finally out in @dev-journal.bsky.social! We investigated an interesting paradox: how can reduced function of the adhesion molecule Echinoid (Ed) cause seemingly opposite phenotypes—overgrowth and elimination—in different contexts? (1/8)

‘It’s really, really bad right now’: NIH scientists dismayed by Trump cuts Researchers say scientific community is in state of whiplash and accuse president of trying to ‘destroy’ vital work

Ctenophores possess a unique aboral organ that acts as a multisensory center, controlling complex behaviors. We’ve now created a ctenophore model integrated with our 3D volume EM data. Puts it into perspective.

Snails with human-like eyes?!

Published in @natcomms.nature.com, the @planaria1.bsky.social & @accorsi-alice.bsky.social Labs have established apple snails as a novel model for studying vision restoration. They have complex camera-type eyes & the ability to regrow them in 28 days: bit.ly/4mvaxkq

We have a postdoc opening for a protistologist with biophysics inclinations to join our @hfspo.bsky.social project! (focus will be on characterising the morphology, ultrastructure and behaviour of excavates) #protistsonsky

Apply by Sept 17th (RTs appreciated!)

Very happy that the first article from my postdoc work in the Tomancak lab is now published @PNAS! www.pnas.org/doi/10.1073/.... We studied the self-organization of actin in aggregates made from Hydra cells. Thread below (1/9)

A genetically tractable non-vertebrate system to study complete camera-type eye regeneration Nature Communications - Accorsi et al. show that the apple snail Pomacea canaliculata has eyes similar to humans and can fully regenerate them. They then developed genetic tools to establish these...

Evolution’s eye game is wild, but mollusks take it to another level

CRISPR in apple snails gives us a new model to dissect how nature rebuilds complex organs like the camera-type eyes we humans possess

It turns out Evolution doesn’t just innovate, it rewinds, remixes, & regenerates
