The double cover of the Barth Decic surface (in the 3-sphere, as opposed to RP3) has 690 singularities. And looks like a Christmas ornament!

Look at the difference coral baby food does! 🪸🍼
The unfed larvae (left) are much slower & travel shorter distances than the fed larvae (right) - like mini Michael Phelps’!
This could have significant promise for reseeding reefs ☺️

If the robin were a squirmer, wonder what kind of flow field it would produce... 🤔

Not sure a Nobel Prize is the answer, but the lack of dedicated theory institutes is a problem. The UK could so easily become a leader in this (and theorists are cheap compared to running an experimental lab!): https://www.thetimes.co.uk/article/its-high-time-there-was-a-nobel-prize-for-mathematics-c0pgd5zss?shareToken=5f0f7944a441f12ed9597278af6cca0f

This stick is of a Plant in the Himalayas called Garud Kashtha meaning Eagle Wood in Sanskrit; it is helical and moves against the flow of water horizontally or vertically; I wonder if plants use it for the transport of pollen, seeds, or migration?

The difference between building a house out of stuff you find laying around and forming one from materials that you made yourself for the purpose. Convergence in function, big difference in approach! #Protists
Cool - now finally a computer game we could get on board with - does it account for hydrodynamic interactions tho😅

YES! as much as we love sampling - we must also keep supporting culture collections! they do such an important job and are indispensable for fundamental research

The motility of the outer hair cells provides an active mechanism for cochlear amplification helping the inners in their fine frequency selectivity. Their stereocilia are filled with parallel actin filaments and dense molecular complexes at the lower and upper tip-link ends.
