Origin of life: β‐sheet amyloid conformers as the primordial functional polymers on the early Earth and their role in the emergence of complex dynamic networks

open access: yesFEBS Letters, Volume 599, Issue 19, Page 2693-2705, October 2025.
The amyloid world hypothesis of the origin‐of‐life posits that the first functional polymers on the early Earth were structurally stable cross‐β‐sheet‐based peptide amyloids capable of Darwinian‐like evolution. Peptide amyloids display self‐replication and information transfer, as well as catalytic, adaptive, and evolutive properties.

Historical paradigm shifts in defining life: from spontaneous generation and vitalism to the Pasteurian Wall and the quest for artificial creation

open access: yesFrontiers in Synthetic Biology
For much of recorded history, the question “Where does life come from?” was answered with certainty: Aristotle’s doctrine of spontaneous generation and staged “ensoulment” defined both natural philosophy and Christian scholasticism.

Subjective Evolution of Consciousness in Modern Science and Vedāntic Philosophy: Particulate Concept to Quantum Mechanics in Modern Science and Śūnyavāda to Acintya-Bhedābheda-Tattva in Vedānta [PDF]

open access: yes, 2019
How the universe came to be what it is now is a key philosophical question. The hypothesis that it came from nothing or śūnya (as proposed by Stephen Hawking, among others) proves to be dissembling, since the quantum vacuum can hardly be considered a ...

Christian Bohr. Discoverer of Homotropic and Heterotopic Allostery

open access: yesActa Physiologica, Volume 241, Issue S734, July 2025.
ABSTRACT This essay recounts and revisits the scientific contributions of Christian Bohr, highlighting his pivotal role in discovering allostery about 120 years ago. Bohr's meticulous experimentation led to identifying two distinct forms of allostery: homotropic (single‐ligand) and heterotropic (multi‐ligand), the latter widely recognized as the Bohr ...

THE PROTOBIOLOGICAL THEORY OF CEILINGS AND FLOORS, OR CHEMICAL EVOLUTION AS A PLANETARY PROCESS [PDF]

open access: yesFilozofia i Nauka
The article presents a modern protobiological theory based on the classical archetype. It connects the issues of origins of life with the theory of the hierarchy of matter and recognizes that error correction occurs within hierarchical and dynamic living

Drake Equation for the Multiverse: From the String Landscape to Complex Life

open access: yes, 2010
It is argued that selection criteria usually referred to as "anthropic conditions" for the existence of intelligent (typical) observers widely adopted in cosmology amount only to preconditions for primitive life.

Chemical Evolution of Early Macromolecules: From Prebiotic Oligopeptides to Self‐Organizing Biosystems via Amyloid Formation

open access: yesChemistry – A European Journal, Volume 31, Issue 29, May 22, 2025.
APR‐A, an aggregation‐prone oligopeptide, can convert into APR‐B through distinct mutational pathways—some exclusively forming insoluble amyloid‐like peptides, others yielding water‐soluble, non‐aggregating monomers. These orthogonal pathways in chemical evolution may have driven macromolecular assembly under prebiotic Earth conditions, potentially ...

Evaluation of antiobesogenic properties of fermented foods: In silico insights

open access: yesJournal of Food Science, Volume 90, Issue 3, March 2025.
Abstract Obesity prevalence has steadily increased over the past decades. Standard approaches, such as increased energy expenditure, lifestyle changes, a balanced diet, and the use of specific drugs, are the conventional strategies for preventing or treating the disease and its associated complications.

Heroical Apatheism: Mala Fide Bootstrapping Obligations [PDF]

open access: yes, 2018
Discussions on hypothetical gods virtually always focus on the latter’s existence or nonexistence. However, this is only the secondary question. Heroical apatheism distinguishes these questions from the primary question, which pertains to the importance ...
