What is the primary stress hormone in the axolotl?
Well turns out they do both cortisol (like fish) and cortocosterone (like most amphibians). And use them under different stressor and with different dynamics.

A digital drawing made from an oil painting by the poster, showing pigeons taking off. The eyes of two birds one on the ground, one in flight, are highlighted. The paper discusses the function of the bird eye - with its inner retina able to sustain high metabolism in anoxia, thanks partially to the action of the pecten - a structure suspended in the back chamber of the eye
Bird's eye view: How do birds' inner retinae work engergetically if they don't have pre-retinal blood vessels? What does the pecten do? If some of these words/concepts sound interesting to you - read www.nature.com/articles/s41...

#ArtAdventCalenday days 13,14,15 #SciArt cross over, sketches of chickens who I study to look at the the condition of keel bone fracture, which occurs very commonly in laying hens in husbandry (~80%). We are looking at the acute consequences to breathing, activity and the potential for pain @au.dk

A better image of microCT and xray diffrqction data from osteoderms! From https://doi.org/10.1002/adfm.202526169
doi.org/10.1002/adfm... the image crop above didnt do justice to Adrian's graphical abstract showing MicroCT and xray diffraction derived data highlighting the different nanocrystalline structures accross different osteoderms. #BluSci #SciArt
Made possible by strong collaboration within @au.dk & internationally @vickaryouslab.bsky.social @anthony-herrel.bsky.social @mmoazen.bsky.social, and funding from @hfspo.bsky.social and @novonordisk.bsky.social via AXIA and enabled by DanMAX @maxivlaboratory.bsky.social. #BluSci #lizard #osteoderm
6 species of lizard and their osteoderms, shown in microCT and xray diffraction data. Two different patterns emerge - the capping tissue is highly mineralised and superficial, but can be highly ordered, or highly disordered and with small or large crystallite volume respectively!
Then we show that the capping tissue of (very) distantly taxa can be also mechanically impressive but with an entirely opposite nano structure (small crystals highly ordered e.g. in Tiliqua in comparison with the large and disordered crystals of Heloderma).
A microCT of a Heloderma osteroderm paired with xray diffraction and xray fluorescence data showing the superficial capping tissue and underlying transition zone and bone.
Stiff and different - Lizard osteoderm papers from a collaboration with @henrikbirkedal.bsky.social's group led by Adrian. We show a capping tissue from Heloderma that is enamel-like in mechanical properties but highly disordered in crystal pattern

A sketch of a presenting scientist talking to a conference presenting work on the links between age, infection status and blood metabolism.
Congratulations on a great talk, blue tits and avian malaria and it's effects on blood metabolism.
Congratulations @aiasdk.bsky.social and all the new fellows, was a pleasure to see 3 minutes of each of their research presented in week one.
