Abiogenesis: can timeless processes be invoked to explain the emergence of life from inert matter?

open access: yesEntropie
In the research on the origin of life, topics that can be considered reasonably shared by the generality of researchers are initially identified.

Photochemical synthesis of natural lipids in artificial and living cells [PDF]

open access: yesNature Communications
Lipid synthesis plays a central role in cell structure, signaling, and metabolism. A general method for the abiogenesis of natural lipids could transform the development of lifelike artificial cells and unlock new ways to explore lipid functions in ...

When Communication Enables Catastrophe: Nuclear Risk and the Short Lifetimes of Technological Civilizations: A Bayesian Scenario Analysis of Civilizational Survival and the Fermi Paradox. [PDF]

open access: yesRisk Anal
ABSTRACT The Fermi paradox may partly reflect technological self‐destruction acting as a Great Filter during post‐industrial development. Because the empirical record consists of a single civilization observed over an eighty‐year nuclear age, the exercise reported here is best understood as a structured, historically anchored scenario analysis rather ...

Potassium at the Origins of Life: Did Biology Emerge from Biotite in Micaceous Clay?

open access: yesLife, 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+.

Xeno Amino Acids: A Look into Biochemistry as We Do Not Know It

open access: yesLife, 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?

The “Odd Inches”: Moby-Dick’s Fossil Record and Melville’s Admeasured Time

open access: yesMiranda: Revue Pluridisciplinaire du Monde Anglophone, 2022
This paper considers the measurements of fossils and markers of geologic time as they appear throughout Moby-Dick, complicating histories of bodies and their remainders. Looking for instances where Ishmael’s measurements fall short or fail to include the

Towards an evolutionary theory of the origin of life based on kinetics and thermodynamics [PDF]

open access: yesOpen 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.

Abiogenesis: The Carter Argument Reconsidered [PDF]

open access: yes, 2022
The observation of life on Earth is commonly believed to be uninformative regarding the probability of abiogenesis on other Earth-like planets. This belief is based on the selection effect of our existence.

The Future of Origin of Life Research: Bridging Decades-Old Divisions

open access: yesLife, 2020
Research on the origin of life is highly heterogeneous. After a peculiar historical development, it still includes strongly opposed views which potentially hinder progress.
