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

Beyond Mediocrity: How Common is Life? [PDF]
The probability that life spontaneously emerges in a suitable environment (abiogenesis) is one of the major unknowns in astrobiology. Assessing its value is impeded by the lack of an accepted theory for the origin of life, and is further complicated by the existence of selection biases.

The Future of Origin of Life Research: Bridging Decades-Old Divisions
Research on the origin of life is highly heterogeneous. After a peculiar historical development, it still includes strongly opposed views which potentially hinder progress.

Did Homocysteine Take Part in the Start of the Synthesis of Peptides on the Early Earth?
Unlike its shorter analog, cysteine, and its methylated derivative, methionine, homocysteine is not today a proteinogenic amino acid. However, this thiol containing amino acid is capable of forming an activated species intramolecularly.

The origin of life: what we know, what we can know and what we will never know [PDF]
The origin of life (OOL) problem remains one of the more challenging scientific questions of all time. In this essay, we propose that following recent experimental and theoretical advances in systems chemistry, the underlying principle governing the ...

Biblical Perspectives as a Guide to Research on Life’s Origin and History
The more than thirty spacetime theorems developed over the past five decades establish that the universe and its spacetime dimensions have emerged from a cause/causal agent beyond the cosmos.

Straightforward Creation of Possibly Prebiotic Complex Mixtures of Thiol-Rich Peptides
At the origin of life, extremely diverse mixtures of oligomers and polymers could be obtained from relatively simple molecular bricks. Here, we present an example of the polymerization of two amidonitriles derived from cysteine, Cys-Ala-CN and Cys-Met-CN.

The alkaline-hydrothermal-vent theory for the origin of life predicts the spontaneous reduction of CO2, dissolved in acidic ocean waters, with H2 from the alkaline vent effluent.
