What determines how epithelial cells divide when shape cues disappear? Our new work in @natcomms.nature.com shows that divisions follow maximal stress anisotropy — a “principal-stress rule” beyond Hertwig’s long-axis rule. Fantastic work led by @luanger.bsky.social www.nature.com/articles/s41...

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

Thus, the coupling between anisotropic stress and proliferation resembles a mechanostat: proliferating tissues can reach lower stress anisotropy through the feedback control of cell division, providing a mechanical "path" toward tissue mechanical homeostasis.
Negative feedback loop between anisotropic stress and cell proliferation

Lucas Anger @luanger.bsky.social · 17/07/2026
This principal stress rule reveals a mechanical feedback loop: anisotropy sets division orientation and scales with cell-cycle duration. After cytokinesis, anisotropic stress is relieved. Importantly, the rule depends on anisotropy, not pressure: it holds for both tension and compression.
100
Lucas Anger @luanger.bsky.social · 17/07/2026
This result integrates previous observations on the mechanical regulation of division orientation, including seemingly conflicting ones. By measuring the intercellular stress tensor, we identify anisotropic stress as a unifying mechanical cue within a common anisotropic framework.
100
Lucas Anger @luanger.bsky.social · 17/07/2026
That is a lot of questions, but we found a surprisingly simple answer: across multiple cell lines and even intestinal organoids, cells tend to divide along the principal direction of intercellular stress.
100
Lucas Anger @luanger.bsky.social · 17/07/2026
But these mechanical cues can sometimes compete. This led us to ask: is there a unifying mechanism underlying these apparent discrepancies? What happens in hexagonal cells without a well-defined long axis? How does this fit into a homeostatic perspective?
100
Lucas Anger @luanger.bsky.social · 17/07/2026
Cells both sense and reshape their mechanical environment. During division, geometry guides division orientation (✨Hertwig's rule✨), while isotropic stresses regulate proliferation, with tension generally promoting and compression inhibiting cell-cycle progression.

Finally! 🤩 Our position piece: Against the Uncritical Adoption of 'AI' Technologies in Academia: doi.org/10.5281/zeno... We unpick the tech industry’s marketing, hype, & harm; and we argue for safeguarding higher education, critical thinking, expertise, academic freedom, & scientific integrity. 1/n
Abstract: Under the banner of progress, products have been uncritically adopted or
even imposed on users — in past centuries with tobacco and combustion engines, and in
the 21st with social media. For these collective blunders, we now regret our involvement or
apathy as scientists, and society struggles to put the genie back in the bottle. Currently, we
are similarly entangled with artificial intelligence (AI) technology. For example, software updates are rolled out seamlessly and non-consensually, Microsoft Office is bundled with chatbots, and we, our students, and our employers have had no say, as it is not
considered a valid position to reject AI technologies in our teaching and research. This
is why in June 2025, we co-authored an Open Letter calling on our employers to reverse
and rethink their stance on uncritically adopting AI technologies. In this position piece,
we expound on why universities must take their role seriously toa) counter the technology
industry’s marketing, hype, and harm; and to b) safeguard higher education, critical
thinking, expertise, academic freedom, and scientific integrity. We include pointers to
relevant work to further inform our colleagues.Figure 1. A cartoon set theoretic view on various terms (see Table 1) used when discussing the superset AI
(black outline, hatched background): LLMs are in orange; ANNs are in magenta; generative models are
in blue; and finally, chatbots are in green. Where these intersect, the colours reflect that, e.g. generative adversarial network (GAN) and Boltzmann machine (BM) models are in the purple subset because they are
both generative and ANNs. In the case of proprietary closed source models, e.g. OpenAI’s ChatGPT and
Apple’s Siri, we cannot verify their implementation and so academics can only make educated guesses (cf.
Dingemanse 2025). Undefined terms used above: BERT (Devlin et al. 2019); AlexNet (Krizhevsky et al.
2017); A.L.I.C.E. (Wallace 2009); ELIZA (Weizenbaum 1966); Jabberwacky (Twist 2003); linear discriminant analysis (LDA); quadratic discriminant analysis (QDA).Table 1. Below some of the typical terminological disarray is untangled. Importantly, none of these terms
are orthogonal nor do they exclusively pick out the types of products we may wish to critique or proscribe.Protecting the Ecosystem of Human Knowledge: Five Principles
