Simple neutrally stable structures can be stitched together into assemblies to create (almost) any shape - totimorphs! See pnas.org/content/118/42… and seas.harvard.edu/news/2021/10/s…

How can one reconfigure a compact planar shape into another ? And do so without changing any lengths/angles? Kirigami shows a new way ... and also solves an old problem by cutting a circle to square it. See journals.aps.org/prresearch/abs…

Brushing a hair curl links topology, geometry, mechanics and some pain (hopefully not too much!). A minimal model of the process is that of a single tine combing a double helix. For more, see pubs.rsc.org/en/Content/Art…

A saw bent into a J sounds dull. But shape it into an S and it can sing! Why? Because of an inflection line in curvature associated with broken (inversion) symmetry - leading to topologically protected modes. For more, see here pnas.org/doi/10.1073/pn…

Physical intelligence? Emergence of cooperative excavation in ants and r(obotic)ants follows from simple local rules and a malleable environment that is a dynamic communication channel. See elifesciences.org/articles/79638

In multi-agent societies, excessive cooperation -> senescence/aging, while excessive competition -> cheating/cancer. So is there an optimal level of competition to delay (the inevitability of) aging? Yes! For more, see tinyurl.com/mvap8e28

What is the cognitive basis for visual image categorization into small/large, animate/inanimate, faces/places etc.? Robustness -> invariant measures combining geometry + statistics -> contour curvature histograms that are neurally plausible! For more, see tinyurl.com/2p97pbfk

"It is not birth, marriage or death, but gastrulation which is truly the most important time in your life'," said Lewis Wolpert. Can one create a gastrulation phase-diagram linking natural history and natural philosophy?... see seas.harvard.edu/news/2023/12/c…

At last we are at the beginning! Linking natural history and natural philosophy, an evolutionary approach to developmental questions starts with the ... egg (which did come before the chick!): tinyurl.com/2cdtjrkm
