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

A carbonate-rich lake solution to the phosphate problem of the origin of life
Proceedings of the National Academy of Sciences of the United States of America, 2019 Significance Phosphate is crucial for the origin of life because it is ubiquitous in key biomolecules. A major issue is that prebiotic syntheses use concentrated phosphate to incorporate phosphate into biomolecules, whereas natural waters are generally ...

Multiverse Predictions for Habitability: Origin of Life Scenarios
Universe, 2023 If the origin of life is rare and sensitive to the local conditions at the site of its emergence, then, using the principle of mediocrity within a multiverse framework, we may expect to find ourselves in a universe that is better than usual at creating ...

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

A Hydrothermal-Sedimentary Context for the Origin of Life
Astrobiology, 2018 Critical to the origin of life are the ingredients of life, of course, but also the physical and chemical conditions in which prebiotic chemical reactions can take place.

Constraining the Time Interval for the Origin of Life on Earth. [PDF]
Astrobiology, 2018 Estimates of the time at which life arose on Earth make use of two types of evidence. First, astrophysical and geophysical studies provide a timescale for the formation of Earth and the Moon, for large impact events on early Earth, and for the cooling of
