this is likely #bioconvection - upswimming of the motile organisms due to combination of light and negative gravitaxis, followed by sinking when the layer becomes too dense https://www.jstor.org/stable/pdf/43421291.pdf

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 ☺️

330 million year old perfection - a wee crinoid ossicle that beautifully highlights their five-fold (pentaradial) symmetry. There’s also a tiny fragment of bryozoan in the bottom right 🖤
Pretty cold out today on campus, why do you ask??
If the robin were a squirmer, wonder what kind of flow field it would produce... 🤔

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😅

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.

How can a single cell learn without a brain? We explore this in my first paper from my PhD with @WallaceUcsf, co-first-authored with @TMakushok! We discovered that gradual habituation in a cell population is due to step-like switches in single cells https://bit.ly/3GNg702

かなりマイナーな霞ヶ浦のプランクトン。メソスティグマ(Mesostigma sp.)。陸上植物に近い系統の藻類で、ミカヅキモなどと同じストレプト植物門に属している（メソスティグマ藻綱）。オレンジ色の眼点と、細胞を取り囲む微細な鱗片が特徴。ひらひらと落葉が舞うように泳ぐよ。
