The start of the Abiogenesis: Preservation of homochirality in proteins as a necessary and sufficient condition for the establishment of the metabolism [PDF]
arXiv, 2018 Biosystems contain an almost infinite amount of vital important details, which together ensure their life. There are, however, some common structures and reactions in the systems: the homochirality of carbohydrates and proteins, the metabolism and the genetics.

An objective Bayesian analysis of life's early start and our late arrival. [PDF]
Proc Natl Acad Sci U S A, 2020 Life emerged on the Earth within the first quintile of its habitable window, but a technological civilization did not blossom until its last. Efforts to infer the rate of abiogenesis, based on its early emergence, are frustrated by the selection effect that if the evolution of intelligence is a slow process, then life's early start may simply be a ...

Potassium at the Origins of Life: Did Biology Emerge from Biotite in Micaceous Clay? [PDF]
Life (Basel), 2022 Intracellular potassium concentrations, [K+], are high in all types of living cells, but the origins of this K+ are unknown. The simplest hypothesis is that life emerged in an environment that was high in K+.

Is Tumorigenesis an Abiogenesis?
Open Access Journal of Cancer & Oncology, 2019 CLN-IgG (Pritumuab) was subjected to clinical trials aiming at regression of brain tumors. The mechanism underlying the dramatic recuperation of cancer patient was considered by means of augmentation of idiotypic antibody-mediated internal image transmission of the vimentin epitope-vipidam. Silencing of prionogenicity of vimentin by chaperonic antibody

Bayesian analysis of the astrobiological implications of life's early emergence on Earth [PDF]
PNAS 109 (2011) 395-400, 2011 Life arose on Earth sometime in the first few hundred million years after the young planet had cooled to the point that it could support water-based organisms on its surface. The early emergence of life on Earth has been taken as evidence that the probability of abiogenesis is high, if starting from young-Earth-like conditions. We revisit this argument

New Experiments on Abiogenesis [PDF]
Nature, 1873 HAVING occupied myself for some time past with an experimental study of abiogenesis, I have followed with much interest the controversies on that question in recent numbers of NATURE, and beg leave therefore to state to the readers of this journal the results of my experiments, which form in my opinion a not unimportant contribution to the solution of ...

The Coevolution of Biomolecules and Prebiotic Information Systems in the Origin of Life: A Visualization Model for Assembling the First Gene. [PDF]
Life (Basel), 2022 Prebiotic information systems exist in three forms: analog, hybrid, and digital. The Analog Information System (AIS), manifested early in abiogenesis, was expressed in the chiral selection, nucleotide formation, self-assembly, polymerization ...
