#Sciart on the nature cover from Richard Tibbets @natureportfolio.nature.com

And here are the sketches from the Bidder lecture, animal presidents talk, Young scientist awards talks for the animal section and some of the other great sessions @sebiology.bsky.social #SEB2026 #sciart

@europexn.bsky.social Sketches of the speakers from todays @sebiology.bsky.social Florence meeting thanks for the great talks!

1st session, the legacy of Hume as the founder of UFAW, the future of #SciFAW - old and new blindspots, fruitful doubt, sympathy with but with minimal sentimentality, 3Rs, research responsibilty and regulation, a history of care and a future of engagement. #SciArt #AnimalWelfare @scifaw.bsky.social

#SciFAW100 Huw Golledge kicks off the conference, in London dealing with the centinary of the university federation of animal welfare - which is now Science for Animal Welfare. #welfare #sciart

The retina is one of the most energetically expensive tissues known to science. And yet, birds’ retinas manage without a key energy-saving tool: oxygen. New research explores how.

“Evolution is not really like an inventor; it acts more like a tinkerer. . . . It takes parts that have existed long before, and it recombines, reinvents, and reshapes.”— Karthik Shekhar, biologist at UC Berkeley

This finding of regeneration in an adult amniote cardiac ventricle has also been independantly come to using different techniques in this paper also out in 2026 doi.org/10.1113/EP09...

Regeneration of the lizard heart after cryoinjuryLizards are renowned for their tremendous potential to heal tissues and organs after injury, but little is known about myocardial regeneration in reptiles generally. Here, we study cardiac regenerati....doi.org

Gecko hearts (here the ventricle) can regenerate! Proud to have been part of this @vickaryouslab.bsky.social study led by Kathy, which looked at function: ultrasound for all and pressure volume loops at final time point, and structure: histology, and transcription over 100d after cryo injury

We know many fish and amphibians can regenerate the heart. How about reptiles? A landmark paper from @vickaryouslab.bsky.social to fill this gap. Glad to be a part of this study. @isrbio.bsky.social @evodevopanam.bsky.social @socdevbio.bsky.social www.nature.com/articles/s41...

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. Paper #blusci #axolotl rdcu.be/e6pzr

The adrenal stress response involves distinct dynamics of both cortisol and corticosterone in the axolotl salamanderLab Animal - This study examines adrenal stress responses and injury signals in axolotl, showing that corticosterone dominates after amputation, while cortisol, which rises with handling stress, is...rdcu.be

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?

#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

#ArtAdventCalendar day 10, a wild boar, inspired by the Celts exhibition at #MoesgaardMuseum where there was also a beautiful stag rising sculpture in iron.
