With talks on topics from blood cell cancers, light and the 👁 , how to teach physiology, gas exchange, metabolism, lungs 🫁 and their differences between sexes and the effect of gender via different risk exposures.

What is #IUPS2025 ? - the conference bringing physiologists from across the world,with @physoc.bsky.social , SPS and DPG, -
The 2 Nobel prize lectures, on low oxygen and high resolution respectively from Peter Radcliffe and Stefan Hell. 🔬
Peter Radcliffe discussing hypoxia sensing, oxygen from history, publishing and future perspectives Stefan Hell discussing limits and non limits to light microscopy

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.

@markscherz.bsky.social talking miniaturisation in 🐸 🦎 🐦 and mammals, in terms of the potential for evolutionary novelty as well as constraints... to the Zoophysiology Friday seminar @au.dk #Frog #Sciart from his @erc.europa.eu funded project
Sketch of a scientist and two frogs... one much bigger than the other. And notes on cell number vs cell size, with the latter constrained by genome size and the former potentially by organ function The same scientist and this time a tiny frog (Mini mum?) Facing forwards and walking in a way favoured by the very small The physical limits of miniaturisation?

This was an excellent 🐕 session @anatomyorg.bsky.social covering canine behaviour and brains, stress and welfare and anatomy of the African wild dog. 3 brilliant talks by Profs Erin Hecht, Ana Jimenez and @heatherfsmith.bsky.social.
Erin Hecht summarising work on behaviour and brains over canine evolution from wolf ancestors, commensal dogs and domestic dogs accross breeds. Ana Jimenez on oxidative stress /reactive oxygen species and stress in dogs. The relationship of lifespan and ROS in dogs over size ranges and between wolves, dogs and wolf-dogs. Heather Smith presenting work on muscles of facial expression, mastication and running in the African wild dog.

Pleasure to speak in this session (sketches of speakers- thanks to Sam Payne for doing me). Talking lizard 🦎 osteoderms: work @hfspo.bsky.social @maxivlaboratory.bsky.social from a large group including @mmoazen.bsky.social @henrikbirkedal.bsky.social- thank you @anatrecord.bsky.social for invite!
A sketch of me by Sam Payne talking lizard osteoderms especially their capping tissue. From work in Matt Vickaryous' lab at Guelph and in collaboration with many international authors, most recently Henrik Birkedal's lab at Aarhus as well as an HSFP funded group led by Mehran Moazen at UCL. Highlighted papers included those led by Loïc Kèver, Arsalan Marghoub, Anastasiia Maliuk, and unpublished work led by Adrian Roderiguez Palamo and Gabriella Willan. Sketches of session chair Jessica Dennis and introducing editor Jason Organ Masterful overview of skin development, anatomy and histology by Prof Tamara Franz-Odendaal Technological revelations from Prof Paul Dalton covering materials for basic research, clinical use and animal use replacement in research: electrowriting structures to mimic skin from basement membrane to superficial layers and dermis

Greatly appreciated the plenary speech by @carlzimmer.com @anatomyorg.bsky.social drawing on material from 'she has her mother's laugh' to discuss Anatomy and its relationship to heredity, its history, mis use and the necessity of communicating current science.
A sketch of Carl Zimmer delivering a plenary speech for the American Association of Anatomists, drawing on material on heredity, on the history of modern (18th-21st centuary) anatomy, including its mis use in eugenics and the necessity of confronting this history and communicating current science.

What 🐎 parasites are there? What have we done historically & presently to 'treat' them as vets, what resistance to anti-parasite drugs are we now seeing? What can we do differently in the future... seminar @ AU from Prof Martin Nielsen #VetSci 🧪 #Parasitology 🐡 doi.org/10.1016/j.vetpar.2011.10.012
A sketch from a talk by Professor Martin Krarup Nielsen on equine parasitology, the normality of parasites, talking about what anti-helmintic (anti-worm) drugs have been previously used in horses, the development of resistance, and the importance of control mechanisms that do not depend on drugs.

@lbejder1971.bsky.social at @aiasdk.bsky.social seminar - Humpback 🐋: how their migration & body condition score is studied, what this can tell us about population, calf size & how this affected by changes to the climate. Can charismatic mammals be used to bring about human change? #Sciart #Blusci
Sketch of Prof Lars Bejder giving the seminar of the week on body condition scores (how much blubber) of humpback whales on their migrations back and forth from Hawa'i (giving birth) to Alaska (feeding), and how this feeds into numbers and size of whales born. Also the cross over with other organisms (e.g. krill), methods (e.g. drone measurements and non invasive tags and samples, and how we as humans think about both whales and the general environment.

And it's always great to be able to include the species of interest as well. I would have thought professional rates for graphic recording would be worth asking e.g. drawingchange.com

I've done non-professional live sketching at talks for my own memory and as gifrs for speakers, with my handwriting therefor limiting understanding but have enormous respect for the #GraphicRecording ers who can get the red thread through an entire session. Also boosting question to #SciArt thread.

Back in September, I was one of 36 new fellows @aiasdk.bsky.social, I drew the other 35's 3min speed talks, and the resulting sketches have just gone in virtual display at the website: aias.au.dk/events/3-min.... Since, I have tried to sketch the Fellows presentations when I've been in the room 🐡

Sign for a new leaf pile. Hoping for hedgehogs. Newly reclassified as "near threatened" hopefully this will remind us to disturb minimally and keep fingers crossed for new slug-lovers.

🧪 because I didn't know how to get this on the #science feed - a paper about what happens to lead pellets in platypuses in museum collections, how this can confuse vets, and some potential implications....
journals.plos.org/plosone/arti... led by Henrik Lauridsen with funding from Carlsberg.
A screen shot of a figure from a paper, showing a fluid preserved platypus with encapsulated radio dense structures in MRI and CT which turned out to be the tissue diffused remnants of lead based shot.

What is up with this #platypus specimen? A new paper from Henrik Lauridsen and colleagues explores the radio dense nodules and found that they were not #VeterinaryPathology, but corrosion products from metal shot. For #opendata #MRI #microCT see journals.plos.org/plosone/arti....
