programming/problem domain aside, what a "blast from the past" with (mostly?) deprecated toolkits/chains/standards:

From yesterday's issue of Science: https://science.sciencemag.org/content/372/6540/eabc6868, Fluctuations shape plants through proprioception Plants constantly experience fluctuating internal and external mechanical cues, ranging from nanoscale deformation of wall components, cell growth variability, nutating stems, and fluttering leaves to stem flexion under tree weight and wind drag. Developing plants use such fluctuations to monitor and channel their own shape and growth through a form of proprioception. Fluctuations in mechanical cues may also be actively enhanced, producing oscillating behaviors in tissues. For example, proprioception through leaf nastic movements may promote organ flattening. We propose that fluctuation-enhanced proprioception allows plant organs to sense their own shapes and behave like active materials with adaptable outputs to face variable environments, whether internal or external. Because certain shapes are more amenable to fluctuations, proprioception may also help plant shapes to reach self-organized criticality to support such adaptability. This review is against the view that plant morphology is simply a deterministic developmental program with environmental noise imposed on it. -- rec -- On Fri, Apr 23, 2021 at 2:29 PM Steve Smith <[hidden email]> wrote:

Roger -
I got stopped at the paywall for the
full text but from the abstract I was a little befuddled. What I
*wanted* to read/hear/believe was that thier use of
"proprioception" is an example of the plant maintaining/developing
a "model" of the past (and therefore potential future) range of
motion/stress of it's elements which is then used to guide it's
development even when it isn't under immediate deformation?
The abstract seems to use
"proprioception" to imply that the plant somehow collectively
generates some movement like what was being induced on it by the
environment, even when it isn't being distorted/stressed from the
outside?
Probably it is more clear in the full
article.
