The paper develops a multiscale model of bud-dormancy break in hybrid aspen trees, showing how tissue-level decisions are influenced by both cellular interactions and organismal constraints.

The paper shows that biochemical reaction diversity across organisms follows predictable scaling patterns, revealing convergent functional constraints independent of phylogeny or reaction identity.

The paper uses functional connectivity networks to analyze calcium dynamics in non-neural tissues, revealing non-random structural and informational patterns post-injury.

The paper demonstrates that the measure {Phi} in Integrated Information Theory is not uniquely defined, showing non-unique values arise from degeneracies in its calculation and introducing a tool to explore the full spectrum of possibilities.

The paper identifies universal scaling laws in enzyme functions across diverse organisms, suggesting a new form of biochemical universality.

The paper analyzes biochemical networks from individual and ecosystem-level data to show they are not scale-free, with no sharp transition in network structure across levels.

This paper assesses the viability of biochemical networks on other planets using Earth's geochemical data and planetary observations, finding that Enceladus lacks necessary compounds for alkaline prokaryotes' metabolism.

The paper constructs global biochemical networks from genomes and reactions to reveal universal scaling laws across biological organization levels.
