Can mathematics explain how biological patterns are formed? Alan Turing thought so. Join me, @benswedlund.bsky.social , as we explore his reaction-diffusion theory and how it transformed our understanding of pattern formation and self-organisation.

Tissue morphogenesis demands massive deformations, yet tissues must stay coherent. This is achieved through cell intercalation, also known as T1 transitions. But what drives them mechanically? I'm @arturruppel.bsky.social, and I'll walk you through the physics, from whole embryos down to four cells

#DBfeature Elongation of the nascent avian foregut requires coordination of intrinsic and extrinsic cell behaviors By Olivia Powell, Emily Garcia, Vanshika Sriram, Yi Qu, Nandan L. Nerurkar tinyurl.com/52pecyc5
Endodermal tissue deformations at the AIP during foregut elongation. (A) Velocity fields quantified from time lapse of cell movements between HH stages 8+ and 10+. Orientation and magnitude of arrows indicate orientation and speed of cell movements, respectively; underlying heat map indicates speed (n = 3); scale = 200 μm. (B) Principal strain rates computed from velocity fields in (A), where major and minor cruciform axes represent maximum and minimum principal strain rates D1 and D2, respectively, and their orientations represent the associated principal directions. Negative/compressive principal strain rates are indicated in blue, and positive/extensional strain rates are indicated in red; strain rate scale = 0.01 %/s; spatial scale is as in (A). (C) Maximum and minimum principal strain rates calculated from velocity fields at HH stage 8, following electroporation with 3 nls-GFP RNA control (left) and DeAct-GFP RNA (right) (n = 3);
