Nature Physics! It illustrates how architecture and active stress mutually regulate Criticality and exhibit Anderson Localization-like phenomenon. www.nature.com/articles/s41...
Feedback between F-actin organization and active stress governs criticality and energy localization in the cell cytoskeleton - Nature Physics
Self-organized criticality can occur in cellular systems, but its origins remain unclear. Now it is shown that cytoskeletal criticality is influenced by the F-actin architecture and myosin active stre...

Reminder: Nobel-prize winning PCR (1983), used in basically all genetic tech today, was only possible because of extremophile bacterium discovered in 1964 in Yellowstone funded by a small ~$80k NSF grant with no obvious application at the time. #science 🧪

It's an interesting phenomenon that some of the deepest questions about how life works have become what looks like impossibly obscure molecular biology stuck right at the back of Nature, which will never get covered by the science media. Like this. /1

Collective cell migration is fascinating!
Some tissues behave like fluids (motile), others like solids (jammed).

Check out some papers exploring this topic in this thread.

Tissue-like multicellular development triggered by mechanical compression in archaea
The advent of clonal multicellularity is a critical evolutionary milestone, seen often in eukaryotes, rarely in bacteria, and only once in archaea. We show that uniaxial compression induces clonal mul...
