Surface‐Driven Protocell Formation in Geologically Relevant Early Earth Environment

open access: yesChemSystemsChem, Volume 8, Issue 2, March 2026.
Illustration of a prebiotic early‐Earth environment showing cell‐like protocells (blue spheres) and other complex organic molecules (pink and green spheres) distributed across terrestrial surfaces and within subsurface niches. Volcanic landscapes and mineral‐rich substrates provide diverse geochemical settings for the assembly and evolution of ...

Temporal Control Over Complex, Simple, and Multiphase Coacervates Using Ureolysis and Ammonium Carbonate Decomposition

open access: yesChemSystemsChem, Volume 8, Issue 2, March 2026.
A new strategy for temporal control over simple and complex coacervates is described here. The urea‐urease reaction results in the timed formation and/or destruction of complex coacervates after controllable delays. This strategy is easily adaptable to different time scales and polyelectrolyte pairs.

The RNA-DNA world and the emergence of DNA-encoded heritable traits

open access: yesRNA Biology
The RNA world hypothesis confers a central role to RNA molecules in information encoding and catalysis. Even though evidence in support of this hypothesis has accumulated from both experiments and computational modelling, the transition from an RNA world

Fundamental Molecules of Life are Pigments which Arose and Evolved to Dissipate the Solar Spectrum

open access: yes, 2014
The driving force behind the origin and evolution of life has been the thermodynamic imperative of increasing the entropy production of the biosphere through increasing the global solar photon dissipation rate.

On RAF Sets and Autocatalytic Cycles in Random Reaction Networks

open access: yes, 2014
The emergence of autocatalytic sets of molecules seems to have played an important role in the origin of life context. Although the possibility to reproduce this emergence in laboratory has received considerable attention, this is still far from being ...
