Molecular Dissipative Structuring: The Fundamental Creative Force in Biology [PDF]

open access: yesEntropy
The spontaneous emergence of macroscopic dissipative structures in systems driven by generalized chemical potentials is well established in non-equilibrium thermodynamics.

Amniotic Fluid and Ocean Water: Evolutionary Echoes, Chemical Parallels, and the Infiltration of Micro- and Nanoplastics [PDF]

open access: yesToxics
Background: Abiogenesis is hypothesized to have occurred in the aquatic environments of the early Earth approximately 3.8–4.0 billion years ago, in oceans containing high concentrations of ions (Na+ ≈ 470 mmol/L, Cl− ≈ 545 mmol/L, Mg2+ ≈ 51–53 mmol/L ...

Positive Microbiology in the Movies [PDF]

open access: yesMicrobial Biotechnology, Volume 18, Issue 9, September 2025.
How ‘Positive Microbiology’ is portrayed in commercial movies and its potential as a tool for education and engaging general audiences to counteract germaphobia. Image done with freepik. ABSTRACT Microbes are essential for sustaining life in our planet.

The hierarchical organization of autocatalytic reaction networks and its relevance to the origin of life. [PDF]

open access: yesPLoS Computational Biology, 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.

Tricks of Nature From the Ancient Earth and Early Mars: Chemical Gardens Generate Biomorphs With High Preservation Potential [PDF]

open access: yesGeobiology, Volume 24, Issue 2, March/April 2026.
ABSTRACT Observations of morphology are commonly used to evaluate the biogenicity of terrestrial microfossils and could constitute a crucial line of evidence for extraterrestrial life‐detection missions in the future. However, evaluating the origin of morphological features in the rock record can be problematic because naturally occurring abiotic ...

An Objective Bayesian Analysis of Life's Early Start and Our Late Arrival [PDF]

open access: yesProc 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 ...

Panspermia versus Abiogenesis: A Clash of Cultures

open access: diamondJournal of Scientific Exploration, 2022
We are too often led to believe that strident denunciations of an unorthodox position in science are always based upon rational argument and irrefutable fact.  This is clearly not so in many instances, one of which relates to panspermia and the dispersal of life throughout the universe. We are led to believe that from the beginning of the enlightenment

Reproducible Ala-Gly oligomerization catalyzed by the natural Borate colemanite in prebiotic conditions [PDF]

open access: yesScientific Reports
The abiogenesis of complex peptides is a yet unsolved problem concerning the origin of life, as it is unclear how specific amino acid sequences could be formed in the absence of a regulation mechanism.

On the feasibility of nonadaptive, nonsequential abiogenesis

open access: gold
The emergence of life from non-living matter remains one of the most profound unresolved questions in natural philosophy. Classical models derived from the Oparin-Haldane hypothesis assume a gradual (sequential), selective assembly of biological precursors.
