You know what's also interactive? Reading the paper. Talk to your colleagues about the paper you just read. Tell them why you loved it. Tell them why you hated it. And even better: invite the authors to talk about their paper 🧪

This is the future of scientific papers.

Instead of a PDF, the paper is an AI agent that you can talk to, ask questions, run analyses.

No more digging through supplements - just ask the paper directly: "what p-value cutoff was used in Fig 3B? Re-run at 0.01."

Biophysics of lumen morphogenesis

Read this Review from our special issue #DevSIextracellular by Byung Ho Lee, @hiraiwatetsuya.bsky.social, Masaki Sano, Alf Honigmann, Daniel Riveline, @anne-grapin.bsky.social and colleagues.

doi.org/10.1242/dev....
Physical principles governing lumen formation and tissue morphology. (A) A lumen surrounded by an epithelial cell layer is shaped by the balance between luminal pressure and mechanical resistance from the tissue and the ECM layers. Ion pumping (Jion) generates a gradient of ions across the monolayer and an osmotic pressure difference (ΔΠ). Water can enter through a flux (Jwater), which generates a hydrostatic pressure difference, ΔP, that can expand the lumen. This hydrostatic pressure is opposed by cortical tensions at the apical, basal and lateral cell surfaces, respectively (γapical, γbasal and γlateral), by cell–cell adhesion, nadh, and by the elastic and viscous properties of both the tissue and the ECM. The detailed inset illustrates how cell division time and tissue osmolarity contribute to the evolving mechanical state of the organoid. Osmotic pressure triggers the generation of hydrostatic pressure, which is faced by the cell monolayer and might, in turn, increase its mass by proliferating. Timescales of increase in luminal volume, cell proliferation, tissue and ECM viscosities contribute to determining the lumen shape. (B) Young–Laplace law applied to the curved epithelial/luminal interface. The pressure difference across the tissue layer depends on cortical tension and curvature according to the Young–Laplace equation (Box 1). Here, R1 and R2 are the two principal radii of curvature of the curved interface. They originate from the fact that a three-dimensional surface can bend along two independent directions. For a spherical lumen, the two radii are equal, whereas for an irregular or elongated lumen, they may differ locally.

My first paper is officially out in @currentbiology.bsky.social ! We found that snake embryos coil due to a mismatch in growth rates between the gut and spine. This tight coil is one of the reasons why snakes are able to get so long. Read the paper here!

We made it completely open-source and even created a visual inspection tool for you to refine the results ("human-in-the-loop", the computer people would say)
Figure 1 of the paper, showing the worflow: it includes TB-scale pretraining, silver-label training, gold-label training, abd curation through one-click refinement, human in the loop and network fine tuning. Lots of colorful images of cells, membranes, nuclei

Photo by Kort Duce A great blue heron checks its surroundings after waking up from a nap during a spectacular sunrise at a nature area in Longmont, Colorado. In this vertical color photograph, a great blue heron stands on one leg atop a partially submerged log, facing the camera with its head turned to its right and its eye wide open. The weathered log is surrounded by countless upright branches, each draped in delicate spider webs that glow as they are backlit by the rising sun. The entire scene is bathed in warm golden and orange hues from the sunrise. Cottonwood seeds, feathers, and other organic debris drift across the water's surface, catching and refracting the light to create delicate circular bokeh highlights. The heron's reflection extends out of the bottom of the frame, joined by the reflection of the surrounding branches. Gentle ripples spread across the pond, gradually widening toward the foreground. The lower half of the image glows with the most intense golden light as the sun's rays illuminate the water. A peaceful portrait of a great blue heron resting in the heart of a thriving wetland, highlighting the beauty of these fragile habitats that are essential to the survival of this remarkable species.
