# phyto: photosynthesis also occurs through far-red light

AA << studied photosystem complexes from cyanobacteria grown in the presence of far-red light. >>

<< Kinetic measurements demonstrated that far-red light is capable of directly driving water oxidation, despite having less energy than the red light used by most photosynthetic organisms. >>

# phyto: a molecular compass to coordinate growth

<< Using this protein [protein BASL: Breaking of Asymmetry in the Stomatal Lineage] to detect the polarity field is like switching a light on in each cell across the tissue. It allows us to see that these cells all have a compass, pointing in the same direction across the leaf >>

<< In this way we will find out if, as we suspect, this molecular compass is a conserved mechanism in the development of plant shapes across the plant kingdom which could be co-opted in different ways by different branches of evolution. >> Catherine Mansfield.

sarebbe davvero singolare, sorprendente, se, dopo l'analisi dei dati, una AI "decidesse" di scrivere il report finale in forma poetica, magari con un approccio quasistocastico, fuzzy, per la stesura del testo ...

# gst: ordered patterns found when mixing granular matter

AA << report remarkably persistent mixing and non-mixing regions in a three-dimensional dynamical system where randomness is expected. A spherical shell half-filled with dry non-cohesive particles and periodically rotated about two horizontal axes generates complex structures that vary non-trivially with the rotation angles. >>
