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+.

The hierarchical organization of autocatalytic reaction networks and its relevance to the origin of life. [PDF]
PLoS Comput Biol, 2022 Prior work on abiogenesis, the emergence of life from non-life, suggests that it requires chemical reaction networks that contain self-amplifying motifs, namely, autocatalytic cores.

Emergence of life in an inflationary universe. [PDF]
Sci Rep, 2020 Abiotic emergence of ordered information stored in the form of RNA is an important unresolved problem concerning the origin of life. A polymer longer than 40--100 nucleotides is necessary to expect a self-replicating activity, but the formation of such a long polymer having a correct nucleotide sequence by random reactions seems statistically unlikely.

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 ...

Synthesis and Characterization of Amino Acid Decyl Esters as Early Membranes for the Origins of Life. [PDF]
Membranes (Basel), 2022 Understanding how membrane forming amphiphiles are synthesized and aggregate in prebiotic settings is required for understanding the origins of life on Earth 4 billion years ago.

The HOMO-LUMO Gap as Discriminator of Biotic from Abiotic Chemistries. [PDF]
Life (Basel)Low-molecular-mass organic chemicals are widely discussed as potential indicators of life in extraterrestrial habitats. However, demarcation lines between biotic chemicals and abiotic chemicals have been difficult to define.

Xeno Amino Acids: A Look into Biochemistry as We Do Not Know It
Life, 2023 Would another origin of life resemble Earth’s biochemical use of amino acids? Here, we review current knowledge at three levels: (1) Could other classes of chemical structure serve as building blocks for biopolymer structure and catalysis?

Towards an evolutionary theory of the origin of life based on kinetics and thermodynamics [PDF]
Open Biology, 2013 A sudden transition in a system from an inanimate state to the living state—defined on the basis of present day living organisms—would constitute a highly unlikely event hardly predictable from physical laws.
