Discover the secret of #tortoise head scales!
The latest @lanevol.bsky.social study reveals how two distinct systems - chemical reaction-diffusion and mechanical folding - shape their unique features.

Interplay of actin nematodynamics and anisotropic tension controls endothelial mechanics - Nature Physics Blood flow through a vessel deforms vessel walls. Cells lining these walls sense the changes in pressure as blood flows and reorient their actin fibres in the direction of largest tension.

How do blood vessels adapt to pressure? 🩸
A new collaborative study from the Salbreux lab shows how changes in endothelial cells help vessels stretch and stay strong — thanks to actin fibers and a smart mechanical model.

PMEL is involved in snake colour pattern transition from blotches to stripes - Nature Communications Corn snakes are a useful model organism for studying skin pigmentation. Here they characterize the Terrazzo morph and identify the role of PMEL in the patterning of pigmented cells in the skin, explai...

Also, our study, "PMEL is involved in snake #colourpattern transition from blotches to stripes," shows how a #PMEL mutation causes striped patterns in corn #snakes.

La formation des écailles des crocodiles est guidée par des facteurs mécaniques Une étude révèle que l’apparition des motifs sur la tête des crocodiles ne résulte pas de la génétique, mais d’un processus purement mécanique de compression de l’épiderme.

🧐🔬 Les écailles des crocodiles ne sont pas programmées génétiquement, mais émergent sous l'effet de contraintes mécaniques ! Découvrez comment notre étude éclaire ce phénomène fascinant dans @pourlascience.bsky.social
