Autocatalytic Sets Arising in a Combinatorial Model of Chemical Evolution [PDF]
Life, 2022 The idea that chemical evolution led to the origin of life is not new, but still leaves open the question of how exactly it could have led to a coherent and self-reproducing collective of molecules.

Primitive Photosynthetic Architectures Based on Self‐Organization and Chemical Evolution of Amino Acids and Metal Ions [PDF]
Advanced Science, 2018 The emergence of light‐energy‐utilizing metabolism is likely to be a critical milestone in prebiotic chemistry and the origin of life. However, how the primitive pigment is spontaneously generated still remains unknown.

The Informational Substrate of Chemical Evolution: Implications for Abiogenesis [PDF]
Life, 2019 A key aspect of biological evolution is the capacity of living systems to process information, coded in deoxyribonucleic acid (DNA), and used to direct how the cell works.

CHEMICAL EVOLUTION IN VeLLOs [PDF]
Journal of The Korean Astronomical Society, 2007 A new type of object called "Very Low Luminosity Objects (VeLLOs)" has been discovered by the Spitzer Space Telescope. VeLLOs might be substellar objects forming by accretion. However, some VeLLOs are associated with strong outflows, indicating the previous existence of massive accretion.

A recursive microfluidic platform to explore the emergence of chemical evolution [PDF]
Beilstein Journal of Organic Chemistry, 2017 We propose that a chemically agnostic approach to explore the origin of life, using an automated recursive platform based on droplet microfluidics, could be used to induce artificial chemical evolution by iterations of growth, speciation, selection, and ...

Modelling the Chemical Evolution [PDF]
Proceedings of the International Astronomical Union, 2009 AbstractAdvanced observational facilities allow to trace back the chemical evolution of the Universe, on the one hand, from local objects of different ages and, secondly, by direct observations of redshifted objects. The chemical enrichment serves as one of the cornerstones of cosmological evolution.

Thioesters provide a plausible prebiotic path to proto-peptides
Nature Communications, 2022 One of the early processes enabling the origins of life is thought to be the condensation of building blocks into oligomers and polymers. In this article, the authors report the synthesis of thiodepsipeptides and HS-peptides under mild temperatures and ...

Life, 2022 Researchers have suggested that the condensation of low-molecular-weight aldehydes under basic conditions (e.g., pH > 11) is the prebiotic reaction responsible for the abiotic formation of carbohydrates.

Geochemical evolution of saline formation water of the Mozduran gas reservoir [PDF]
Journal of Stratigraphy and Sedimentology Researches, 2018 The Mozduran gas reservoir in the Khangiran gas-field is formed in the Kopet-Dagh sedimentary basin in the form of sequential sequences of clastic and carbonate sediments of the old sea water.
