Today in ingenious historical experiments: Theodor Engelmann demonstrated that chloroplasts are the site of oxygen production in plants by taking bacteria that would migrate towards oxygen and seeing that they went to the choloroplast

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

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!

zoomies!!

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 belongs in the "real articles that sound fake" hall of fame.

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!): thetimes.co.uk/article/its-hig

Lots of strange goings-on here on the third floor of @LSI_Exeter... Last week it was a pair of dancing elves, today it's strange synchronized singing... Something about... Could it be... Christmas is coming already?? 😉☃️🎄

@barrygoldman1 well yes indeed the video is probably fake but it's a nice concept to think about...

Dead fish have been shown to "swim" upstream but elasticity is required there which doesn't apply here ..

But perhaps microorganisms do!

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!

Cool - now finally a computer game we could get on board with - does it account for hydrodynamic interactions tho😅
