I wrote a nice little article about plankton. With pictures! https://alexandersemenov.substack.com/p/a-look-into-the-open-water
Wonder what's synchronizing them - is it coupling through the sofa...?

In sync.. 😅

This is a fun one. Using a simple model, we derive a Snell-type law for the scattering of microswimmers (active particles) in fluids with sharp changes in viscosity.
@Burnsajohn thanks! Glad you think it might be useful! (Just let me know if anything in the paper is unclear!) Our hope is that people will start applying it to different organisms... 😃 Protists preferred of course...
The puzzle that keeps on giving😜 reminds me of https://doi.org/10.1098/rstb.2019.0566 when the authors ended with: 'a saying attributed to Alfonso X of Castile, ‘el sabio’: ‘If the Lord Almighty had consulted me before embarking on creation thus, I should have recommended something simpler’.

@Burnsajohn haha love the video (imagej??) Much less look up at the stars, more look down at my microscope... And all the twinkling critters 😋

The little #worms in this movie that you see #crawling about are actually tracks outlining the motion of microscopic #algae. Some move fast and have wormy red (fast!) lines, some move slow and have stumpy blue (slow) lines. I've got nothing on @micromotility, but I absolutely enjoy making movies of algae swimming around and thinking about what is causing them to move a particular way!

Our paper is published!
How do bacteria swim and interact with obstacles in a narrow space sandwiched between two no-slip boundaries?
We found enhanced hydrodynamic interactions in such a quasi-2D setup.

very interesting question... #activematter
I reckon that to qualify as a micro/nanorobot the agent should have something beyond just motility - for example a minimal cognition (loosely defined, e.g. phototaxis), though in the literature the term has been used for much less?!

Girls are not put off physics because of "hard maths" (girls got more top grades than boys in A level maths in 2021 & 2022). Instead,

Unfortunately, one of the first things you learn when doing animal behavior research is that the animals don't care what your hypothesis is. #mentorship

We answered the question that "How the embryo senses nodal flow and why only the L-side cilia can respond." Let me guide you! 1/n https://www.science.org/doi/10.1126/science.abq8148

Came back into work this morning to find this intriguing Dorito-shaped contamination on one of my soft agar plates (.25% LB agar). Amazing how the cells have formed such an angular structure, although I’ve no idea what it is! @ContamClub
