Theoretical perspective on synthetic man‐made life: Learning from the origin of life

open access: yesQuantitative Biology, 2023
Creating a man‐made life in the laboratory is one of life science’s most intriguing yet challenging problems. Advances in synthetic biology and related theories, particularly those related to the origin of life, have laid the groundwork for further ...

Necessary and sufficient conditions for protocell growth [PDF]

open access: yes, 2016
International audienceWe consider a generic protocell model consisting of any conservative chemical reaction network embedded within a membrane. The membrane results from the self-assembly of a membrane precursor and is semi-permeable to some nutrients ...

Myth and fact in the origins of cellular life on Earth [PDF]

open access: yes, 2017
Research into the origins of the first protocell is of a multidisciplinary nature. It draws evidence from what we know about the Earth’s early atmosphere and environment, and about the most ancient features of the cell’s structure and composition.

Interface‐Aware Design of Biocatalysis

open access: yesAdvanced Synthesis &Catalysis, Volume 368, Issue 7, 1 April 2026.
Interfaces impact biocatalysis scalability. We reframe gas–liquid, liquid–liquid, and solid–liquid boundaries as design variables, specific interfacial area and renewal rate, that govern activation or deactivation. Mechanistic evidence, quantification tools, and reactor/material strategies enable longer lifetimes and higher integrated productivity by ...

Prebiotic Factors Influencing the Activity of a Ligase Ribozyme

open access: yesLife, 2017
An RNA-lipid origin of life scenario provides a plausible route for compartmentalized replication of an informational polymer and subsequent division of the container.

Multi-level selectional stalemate in a simple artificial chemistry [PDF]

open access: yes, 2007
We describe a simple artificial chemistry which abstracts a small number of key features from the origin of life "replicator world" hypotheses. We report how this can already give rise to moderately complex and counter-intuitive evolutionary phenomena ...

Prebiotic Organic Chemistry of Diketopiperazines

open access: yesAsian Journal of Organic Chemistry, Volume 15, Issue 4, April 2026.
Diketopiperazines (DKPs) are considered essential in many life forms, but their prebiotic importance has not been fully understood. This review aims to discuss prebiotic organic chemistry for experimentally and computationally simulated reactions involving DKPs. ABSTRACT Even though the significance of amino acids and polypeptides is well recognized in

Growth and Division in a Dynamic Protocell Model

open access: yesLife, 2014
In this paper a new model of growing and dividing protocells is described, whose main features are (i) a lipid container that grows according to the composition of the molecular milieu (ii) a set of “genetic memory molecules” (GMMs) that undergo ...
