intriguing considering the evolutionary diversity of #pigment related #sleep regulation:

if we put following 3 papers together,

our new preprint
https://www.biorxiv.org/content/10.64898/2026.05.27.728351v2 by @mehranakhtar

this recent finding
https://www.sciencedirect.com/science/article/pii/S2589004225026495

one would then think that eumelanin pathway regulate sleep without affecting pigmentation in #Drosophila; and although neuromelanin pathway can regulate both pigmentation and sleep, BUT direct selection of pigmentation 👇, didnot change sleep...fascinating

An indigo-based pigment... from an overlooked recipe in a 13th century Arabic text. Fascinating experiments & scholarship from Joumana - & highlighting the digitised manuscript treasures in our libraries!

Si vous me permettez un petit *rant* linguistique : quel bazar, la phtalocyanine ! C'est une substance qui permet entre autre de créer des pigments bleus et verts que j'aime énormément.

*phtalo* vient du grec *naphtha* — lui-même du persan *naft* — dont on a gardé le *ph* mais pas le *th*, et j'ai toujours un doute en l'écrivant car en anglais et en allemand, ça s'écrit… *phthalo-* ! Ce qui a encore moins de rapport avec la prononciation…

Soudain I, Max Ernst, 1962

I love all the texture and the strange density, I think reality has a density that you can always stop to appreciate no matter where you are. The layout of this has a couple of large-scale shapes but there's so much more there because of the texture, like every molecule of yellow and blue and orange etc. is interacting separately with your eyes 🤣

The March installment of Polylith arrives as the last drifts of snow melt. We consider a new sculpture, and a process that loops without ever repeating.
