Autopoiesis Concepts for Chemical Origins of Life and Synthetic Biology [Stenogram of the popular lecture on the foreign bibliographic seminar] [PDF]

open access: yes, 2017
The monograph (Luisi P.L. "The Emergence of Life: From Chemical Origins to Synthetic Biology", 2010, Cambridge University Press, Cambridge, New York etc., 315 p.) is a well-written, informative book providing a novel view on the interrelation between the

Valuing life detection missions

open access: yes, 2018
Recent discoveries imply that Early Mars was habitable for life-as-we-know-it; that Enceladus might be habitable; and that many stars have Earth-sized exoplanets whose insolation favors surface liquid water. These exciting discoveries make it more likely

Abiogenesis: the Carter argument reconsidered

open access: yesInternational Journal of Astrobiology, 2022
AbstractThe observation of life on Earth is commonly believed to be uninformative regarding the probability of abiogenesis on other Earth-like planets. This belief is based on the selection effect of our existence. We necessarily had to find ourselves on a planet where abiogenesis occurred, thus nothing can be inferred about the probability of ...

Chemical Evolution of Early Macromolecules: From Prebiotic Oligopeptides to Self‐Organizing Biosystems via Amyloid Formation

open access: yesChemistry – A European Journal, Volume 31, Issue 29, May 22, 2025.
APR‐A, an aggregation‐prone oligopeptide, can convert into APR‐B through distinct mutational pathways—some exclusively forming insoluble amyloid‐like peptides, others yielding water‐soluble, non‐aggregating monomers. These orthogonal pathways in chemical evolution may have driven macromolecular assembly under prebiotic Earth conditions, potentially ...

Effect of Alkali‐ and Alkaline‐Earth‐Metal Promoters on Silica‐Supported Co−Fe Alloy for Autocatalytic CO2 Fixation

open access: yesAngewandte Chemie, Volume 136, Issue 8, February 19, 2024.
Alkali‐ and alkaline‐earth‐metal‐promoted Co−Fe bimetallic catalysts on silica can convert CO2 and H2O to crucial metabolites such as formate, acetate, pyruvate as well as hydrocarbons under mild hydrothermal vent conditions. With alkali‐ and alkaline‐earth metals abundant in hydrothermal vents, our study simulates how the geochemical process can fix ...

The Nature of Stability in Replicating Systems

open access: yesEntropy, 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 ...

Evaluation of antiobesogenic properties of fermented foods: In silico insights

open access: yesJournal of Food Science, Volume 90, Issue 3, March 2025.
Abstract Obesity prevalence has steadily increased over the past decades. Standard approaches, such as increased energy expenditure, lifestyle changes, a balanced diet, and the use of specific drugs, are the conventional strategies for preventing or treating the disease and its associated complications.

Step‐by‐Step Towards Biological Homochirality – from Prebiotic Randomness To Perfect Asymmetry

open access: yesChemistry – An Asian Journal, Volume 20, Issue 1, January 2, 2025.
This review focuses on the theories related to the emergence of biological homochirality, from assembly of building blocks at the monomer level, to polymerization into functional homochiral biopolymers. Abstract The history of life's formation and the origin of its stereochemistry are nearly as multifaceted as the life itself.

Historical paradigm shifts in defining life: from spontaneous generation and vitalism to the Pasteurian Wall and the quest for artificial creation

open access: yesFrontiers in Synthetic Biology
For 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.
