Wake, NREM sleep, and REM sleep each prioritise different physiological processes, with distinct energetic demands. How maintenance is defined and what constitutes SMR depends entirely on WHEN you measure it. (3/9)

The myth of the metabolic baseline: sleep–wake cycles undermine a foundational assumption in organismal biology Basal and standard metabolic rate (BMR and SMR) are cornerstones of physiological ecology and are assumed to be relatively fixed intrinsic properties of organisms that represent the minimum energy re....

New paper out!! In this review, we discuss what really is SMR when we take into account the sleep state dependent partitioning of the processes that make up this baseline value, and how do we move forward with the assumption SMR isn't a static value.....

Thrilled to have been awarded best poster prize at #ASABwinter2025, alongside two other fantastic posters. Thank you to the organisers for another wonderful ASAB event, full of so many interesting talks and inspiring people.

Congratulations to #ASABWinter2025 best talk winner Jonah Walker (“Multimodal signalling and mate choice across peacock spider species“) and poster winners Helena Norman, Joey Baxter and James Robertshaw 🙌🎨🏆

In our new correspondence, we discuss how light-based methods of sleep disruption may generate confounds that complicate interpretation of results. Light affects hormones, circadian rhythms & stress responses beyond just sleep! @helenanorman.bsky.social onlinelibrary.wiley.com/doi/10.1111/...

New paper out in the Journal of Sleep Research 💤 discussing how using light as a mode of sleep disruption might be disrupting a whole host of other things too... @shaunkillen.bsky.social onlinelibrary.wiley.com/doi/10.1111/...

After so many years of toil, we've finally done it. Definitive proof that guppies can quantum phase shift between dimensions. Congrats to @helenanorman.bsky.social for this game-changing discovery. 🥳 #fishsci

Outstanding talk by @helenanorman.bsky.social for @pintofscience.uk on the nature of sleep in fish and other animals. Incredible that we know so little about this vitally important process. More to come from this fantastic scientist!

First set of Flask talks Day 2 #ASABSPRING2025 @asab.org @ljmuofficial.bsky.social were excellent, looking at sleep behaviour in fish, species network structures, parental care, behaviour plasticity of honey bees, social inheritance and using Python for animal movement

A collage of six slides from the flash talks

Great flash talks 💥 sleep in fish @helenanorman.bsky.social, the friendship paradox @eloisenewman.bsky.social, parental care in roaches: Georgia Cash, behavioural plasticity in bees: Gifty Jacob, social inheritance in red deer: Hannah Lemon, motion tracking: Nikoloz Sirmpilatze #ASABSpring2025 #ASAB
