![Smc3 protein depletion protects lateral line neuromasts from neomycin cytotoxicity. (A) Representative images of lateral line neuromasts in SC-KD larvae and Smc3-KD larvae at 5 dpf with and without neomycin treatment and stained with 2-[4-(Dimethylamino)styryl]-1-ethylpyridinium iodide (DASPEI). Scale bars: 100 µm. (B) Quantification of neuromast survival after neomycin treatment for each injection type. Neuromast survival was calculated as the ratio of observed neuromasts in each neomycin-treated embryo to the average number of neuromasts visible in control-treated embryos of the same injection type (e.g. SC-KD or Smc3-KD). By this method, ratios greater than 1 may occur if the number of observed neuromasts in a neomycin-treated embryo exceeds the average number of neuromasts observed in the relevant control-treated embryos. Student's t-test, ****P<0.0001, SC-KD n=40, Smc3-KD n=36.](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:ckg56sce76vdnqq4yhdlfbts/bafkreibxojvnwje4ncfe2zn3hv5eihsy2w5pirtiv6p6bsyulqd322wzwe)

Fossilized fish ear stones – known as #otoliths – can reveal far more than previously thought.
In a recent study, a team of palaeontologists from #univienna demonstrated that a refined electron microscopy technique can make even the finest growth rings visible. 🐟🔬 #palaeontology

Wow. @universityofessex.bsky.social PhD students Lucy Smith & Izi Firth curated an amazing exhibition: #NaturesCanvas. Who knew our Life Sci dept housed so many talented artists? Glad to see so many #otoliths on display 🐟🥰! And a bell jar filled with crude oil to signify our hypoxia & ecotox work ☠️

Fun to get back into the lab @thembauk.bsky.social today, especially since I was working with #otoliths again, 30 odd years after I started my #marinebiology career with them. All part of our Pollack FISP project www.plymouth.ac.uk/research/mar...

This semester our Uni Iceland Centre hosted a weekly group of 13-15 YO from the #local school 🧪👩🔬
Favorite practical was extracting otoliths and aging cod from the local #fishery vs #otoliths from archeol. dig dating to 900-1600 🐟🎣🌊
2 groups chose to disseminate via tiktok (stills shared with perm)

So proud of my postdoc "Dr Cod" @dubucalexia.bsky.social & Eric Fakan for epic efforts sampling sediment, water, blood & #cod #otoliths all over the #Baltic to explore the mechanisms underpinning oto Mn as a #hypoxia marker. BIG thx to BITS crew & our collaborators at DTU Aqua for their support 🙌

Second half of the little otolith workshop, this time we extracted some eel otoliths, took some muscle samples for PFAS analysis and measured some standard life history stage params (eye diameter, fat content). Love eels, they´re sooo fascinating (alive even more so! 😀) #Scicomm #Science #Otoliths 🧪
