The Nature of Stability in Replicating Systems
Entropy, 2011 We review the concept of dynamic kinetic stability, a type of stability associated specifically with replicating entities, and show how it differs from the well-known and established (static) kinetic and thermodynamic stabilities associated with regular ...

Harnessing Dynamic Self‐Assembly to Accelerate Chemical Reactions
Small Structures, Volume 7, Issue 2, February 2026.Dynamic supramolecular self‐assembly offers a route to regulate chemical reactivity beyond diffusion‐controlled processes. This perspective surveys how dynamic assemblies organize substrates in space and time, increase effective molarity, enable emergent catalysis, and create specified microenvironments to accelerate chemical reactions. Precise control

The HOMO-LUMO Gap as Discriminator of Biotic from Abiotic Chemistries
LifeLow-molecular-mass organic chemicals are widely discussed as potential indicators of life in extraterrestrial habitats. However, demarcation lines between biotic chemicals and abiotic chemicals have been difficult to define.

Rethinking “Prebiotic Chemistry”
Perspectives of Earth and Space Scientists, Volume 6, Issue 1, December 2025.Abstract In origins‐of‐life research, the term “prebiotic chemistry” is commonly used to describe processes thought to be related to or required for the emergence of life. However, it suffers from several potential drawbacks that have caused the present group of authors to rethink their usage of the term.

Journal for the Theory of Social Behaviour, Volume 55, Issue 4, December 2025.ABSTRACT Humanity seems stuck on different ways to fail to meet the challenge posed by a declared climate emergency and manifest problems of ecological breakdown. Rather than reprise these failures, we use the Fermi Paradox and simulation hypothesis to make a simple point about agency. The argument unfolds in two sections.

Frontiers in Synthetic BiologyFor much of recorded history, the question “Where does life come from?” was answered with certainty: Aristotle’s doctrine of spontaneous generation and staged “ensoulment” defined both natural philosophy and Christian scholasticism.

A stepwise emergence of evolution in the RNA world
FEBS Letters, Volume 599, Issue 19, Page 2706-2717, October 2025.How did biological evolution emerge from chemical reactions? This perspective proposes a gradual scenario of self‐organization among RNA molecules, where catalytic feedback on random mixtures plays the central role. Short oligomers cross‐ligate, and self‐assembly enables heritable variations. An event of template‐externalization marks the transition to

FEBS Letters, Volume 599, Issue 19, Page 2693-2705, October 2025.The amyloid world hypothesis of the origin‐of‐life posits that the first functional polymers on the early Earth were structurally stable cross‐β‐sheet‐based peptide amyloids capable of Darwinian‐like evolution. Peptide amyloids display self‐replication and information transfer, as well as catalytic, adaptive, and evolutive properties.

THE PROTOBIOLOGICAL THEORY OF CEILINGS AND FLOORS, OR CHEMICAL EVOLUTION AS A PLANETARY PROCESS [PDF]
Filozofia i NaukaThe article presents a modern protobiological theory based on the classical archetype. It connects the issues of origins of life with the theory of the hierarchy of matter and recognizes that error correction occurs within hierarchical and dynamic living
