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

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 ☺️

Exciting new possibility for young researcher. The LSI call for candidates for externally funded group leader fellowships is launched today with closing dates in January and March. https://twitter.com/LSI_Exeter/status/1602324124239552512?s=20&t=gKl35jQDNvNEs7IzyWOfbw

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😅

A sneak peak at Aggi's Tiny Friends. An educational game about microscopic ecosystems, where you customize a cell of your own to see what can survive. The videos by @JourneyToMicro where a huge help in getting the movement of cells right! @ParameciumP @ProtistologyUK #indiedev

How do swimming microalgae move in snow? And how does this couple to climate change? We have a fully-funded @ONEPlanetDTP PhD opportunity to study in my group in collaboration with @mjsandells, @scienceisnotfun and @xanthellaltd. Please RT. More info here https://tinyurl.com/snowalgaeswim
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
