Protection of liposomes by ferric salts against the UV damage and its implications for the origin of life

Frontiers in Astronomy and Space Sciences
Previously, we presented a hypothesis on the Darwinian evolution of liposomes that relies only on natural and ever-present phenomena: solar UV radiation, day/night cycle, gravity, and the formation/release of amphiphiles in aqueous media.

An Ontological Solution to the Mind-Body Problem [PDF]

, 2017
I argue for an idealist ontology consistent with empirical observations, which seeks to explain the facts of nature more parsimoniously than physicalism and bottom-up panpsychism.

On the Transitional Character and Regularity of Planetary Abiogenesis [PDF]

BioSystems
The emergence of biology from planetary chemistry remains one of the central open questions in science. In this study, we address the core challenge of distinguishing whether abiogenesis is a statistically regular process under broadly defined planetary conditions, or a unique, highly contingent event.

The Impact of Salts on Single Chain Amphiphile Membranes and Implications for the Location of the Origin of Life

Life, 2017
One of the key steps in the origins of life was the formation of a membrane to separate protocells from their environment. These membranes are proposed to have been formed out of single chain amphiphiles, which are less stable than the dialkyl lipids ...

Simple Ion–Gas Mixtures as a Source of Key Molecules Relevant to Prebiotic Chemistry

Molecules, 2021
Very simple chemistry can result in the rapid and high-yield production of key prebiotic inorganic molecules. The two reactions investigated here involve such simple systems, (a) carbon disulfide (CS2) and acetate (CH3COO¯) and (b) sulfur dioxide (SO2 ...

Molecular basis of Arginine and Lysine DNA sequence-dependent thermo-stability modulation.

PLoS Computational Biology, 2022
We have used a variety of theoretical and experimental techniques to study the role of four basic amino acids-Arginine, Lysine, Ornithine and L-2,4-Diaminobutyric acid-on the structure, flexibility and sequence-dependent stability of DNA.

Dependence of Biological Activity on the Surface Water Fraction of Planets

, 2019
One of the unique features associated with the Earth is that the fraction of its surface covered by land is comparable to that spanned by its oceans and other water bodies.

The Evolution of Active Droplets in Chemorobotic Platforms [PDF]

, 2017
There is great interest in oil-in-water droplets as simple systems that display astonishingly complex behaviours. Recently, we reported a chemorobotic platform capable of autonomously exploring and evolving the behaviours these droplets can exhibit.
