Everything living learns, values and adapts. Basal cognition studies how this is done from the 'lower' to the 'higher' evolutionary limbs of the Tree of Life.

The inimitable Harold Franklin blazed the cellular path with accessible books in 2001 & 2014. "Living things are dynamic systems..All their mechanisms are molecular, but it is spatial & structural organization that brings molecules to life." My bet: no cells, no life AWKI.
Interesting essay on an interesting book: is biology best understood from the perspective of a gene, a cell, or a temporally evolving physicochemical system? I know where my intuitions lie… what about you!? science.org/doi/10.1126/sc…
Just checking - C. elegans (and relatives) are still the animal with the fewest neurons, right? It's amazing all the behaviors they have with so few neurons to work with
was looking for one of Howard Berg's beautiful videos of bacteria, dismayed to find that his website no longer exists! rowland.harvard.edu/labs/bacteria/… Could Harvard not keep his website up for posterity?? it's like a piece of biophysics history has been lost... 😧
Nearly all cells in our body have an autonomous circadian clock that controls ~40% of the genome. We show, at the single cell level, that the clock is mechanically controlled through YAP/TAZ. rupress.org/jcb/article-ab… @IBECBarcelona
Can learning and cognition emerge without neurons? Here's a great review of how physical systems can implement neural-like complexity. Thanks to @RichardWatson90 for pointing me to this conceptual framework. @drmichaellevin @UCLALuskin annualreviews.org/doi/pdf/10.114…

Cells can pass proteins and RNA to each other through tubes that act as a channel between their membranes. elifesciences.org/articles/84391…
Boy, ain't it the truth, or 99.9% of it.
Tattooing everything that we're sure about regarding memory encoding in the brain
Brilliant! What a find! Thanks so much. 👏🙏
Euplotes mating swarm that seems to have been induced by a bacterial biofilm? You can always expect some unexpected observations @MBLScience Physiology. The twirling movements of swimming cells, visible in this video, have been described as part of a "mating dance"
Not surprising but still amazing.
Parasites can use extracellular vesicles and cellular projections called cytonemes to communicate with one another. elifesciences.org/articles/89264…
In a recent overnight imaging session, I made a startling discovery... COS7 throw midnight dance parties. Who knew? These party animals are dressed in Vimentin-TagGFP (orange) and the ER marker SnapTag-Sec61b (blue) #FluorescenceFriday
“… rapid, smooth, and continuous rotation of the anterior end of the cell … function of this rotatory movement, the cellular mechanisms enabling it, and the way the cell deals with the consequent cell membrane shear, are all unknown.” Hehenberger et al. doi:10.1111/jeu.12987
Combjellies are zeppelins of the sea (and early-splitting evolutionary branch within metazoans)
What I adore about this video (oh the wonderful toys and equipment you have) is how similar it was to the claymation video @swirlgirl31415 made for me years ago! youtu.be/9EzFJ3AkDKM

Remarkable thread! Creepy, but…rules. Fascinating!

Thanks, Mike. It’s a ripper!
Here's a brand new one, hot off the press: link.springer.com/article/10.100… "Bioelectric networks: the cognitive glue enabling evolutionary scaling from physiology to mind" part of what will be an awesome collection in the journal Animal Cognition: link.springer.com/collections/aa…
Biological self-organisation at its best! 🤩
Here's the hypnotic time-lapse I used : Dictostelium cAMP signal waves are in gold🟧 and nuclei in Blue🟦, enjoy! I used the dataset from this paper : elifesciences.org/articles/83796
Yes. Since the worm, where 40% of the cells manage the other 60%, the brain is in charge. Allostasis reigns! Chronic stress can inflame the gut — now scientists know why nature.com/articles/d4158…
