SYNCHRONIZATION PHENOMENA IN PROTOCELL MODELS

open access: yesBIOMAT 2007, 2008
This work aims to consider simplified models of protocells in order to describe their general behaviors. The advantage of the modelling approach is that the early protocells of life-forms on Earth are not reproduced in the present time. However, the problem is considered as a right track to understand the origin of life as well as to work with more ...

Fast and Slow Signal Propagation in Abiotic Polypeptide Assemblies

open access: yesChemBioChem, Volume 27, Issue 6, 27 March 2026.
Proteinoid microspheres formed by thermal polymerization of amino acids exhibit spontaneous electrical potential fluctuations without genetic material, membranes, or ion channels. Multi‐electrode recordings and electron microscopy reveal composition‐dependent voltage oscillations, long‐term drifts, and correlated signals across electrodes.

Tuning interfacial fluidity and colloidal stability of membranized coacervate protocells

open access: yesCommunications Chemistry
The cell membrane not only serves as the boundary between the cell’s interior and the external environment but also plays a crucial role in regulating fundamental cellular behaviours. Interfacial membranization of membraneless coacervates, formed through

Biomimetic Construction of Abiotic Membranes Through Acylation of Cationic Diamino Acids

open access: yesChemBioChem, Volume 27, Issue 6, 27 March 2026.
Cells produce membrane‐forming phospholipids through complex enzymatic pathways. Here, we present the in situ synthesis of a novel class of abiotic phospholipid analogs (APAs) featuring a permanent choline‐mimetic cation on diamino acid backbones.

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.

The un-designability of the virtual. Design from problem-solving to problem-finding. [PDF]

open access: yes, 2018
Drawing on Gilles Deleuze (1991) this chapter investigates the virtual as what problematizes the possible by inserting contingency in the process of emergence of the new.

Biomimetic Iridescent Skin: Robust Prototissues Spontaneously Assembled from Photonic Protocells

open access: yesAdvanced Functional Materials, Volume 36, Issue 26, 30 March 2026.
Uniform nanoparticles are induced to form arrays (photonic crystals) in the cores of biopolymer capsules, endowing these ‘protocells’ with structural color. These protocells are then assembled into large self‐standing objects, i.e., prototissues, with robust mechanical properties as well as iridescent optical properties.

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

Motility at the origin of life: Its characterization and a model

open access: yes, 2013
Due to recent advances in synthetic biology and artificial life, the origin of life is currently a hot topic of research. We review the literature and argue that the two traditionally competing "replicator-first" and "metabolism-first" approaches are ...
