RNP-world: The ultimate essence of life is a ribonucleoprotein process

open access: yesGenetics and Molecular Biology, 2022
The fundamental essence of life is based on process of interaction between nucleic acids and proteins. In a prebiotic world, amino acids, peptides, ions, and other metabolites acted in protobiotic routes at the same time on which RNAs performed catalysis

The Coevolution of Cellularity and Metabolism Following the Origin of Life

open access: yesJournal of Molecular Evolution, 2020
The emergence of cellular organisms occurred sometime between the origin of life and the evolution of the last universal common ancestor and represents one of the major transitions in evolutionary history.

Nonequilibrium phase transitions in a model for the origin of life [PDF]

open access: yes, 2001
The requisites for the persistence of small colonies of self-replicating molecules living in a two-dimensional lattice are investigated analytically in the infinite diffusion or mean-field limit and through Monte Carlo simulations in the position-fixed ...

Hygiene Quality and Consumer Safety of Traditional Short- and Long-Ripened Cheeses from Poland

open access: yesJournal of Food Quality, 2018
The aim of this study was the assessment of the microbiological quality of three types of traditional cheeses which are produced from raw and pasteurized cow’s milk. Two types of cheeses were of the short-ripened type, and one cheese was long-ripened.

Acromegaly, Mr Punch and caricature. [PDF]

open access: yes, 1996
The origin of Mr Punch from the Italian Pulcinella of the Commedia dell'arte is well known but his feature, large hooked nose, protruding chin, kyphosis and sternal protrusion all in an exaggerated form also suggest the caricature of an acromegalic. This

Origin of life in a digital microcosm

open access: yes, 2017
While all organisms on Earth descend from a common ancestor, there is no consensus on whether the origin of this ancestral self-replicator was a one-off event or whether it was only the final survivor of multiple origins.

Quantum Criticality at the Origin of Life [PDF]

open access: yes, 2015
Why life persists at the edge of chaos is a question at the very heart of evolution. Here we show that molecules taking part in biochemical processes from small molecules to proteins are critical quantum mechanically.
