Panspermia versus Abiogenesis: A Clash of Cultures

Journal 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

Hybrid Life: Integrating biological, artificial, and cognitive systems

WIREs Cognitive Science, Volume 14, Issue 6, November/December 2023., 2023
Hybrid Life brings attention to some recent developments within the Artificial Life community, focusing on the integration of three themes: theories of systems and agents, hybrid augmentation combining living and artificial systems, and hybrid interactions among artificial and biological systems.

Quantifying Catalysis at the Origin of Life**

Chemistry – A European Journal, Volume 29, Issue 53, September 21, 2023., 2023
Origin of life theories often invoke catalytic mechanisms, but catalysis of biologically relevant reactions in geologically plausible scenarios has been until recently experimentally elusive. In this perspective, we suggest that researchers move toward decreased catalyst loading, increased yields, as well as before/after characterization of metals or ...

Microfluidic Reactors for Carbon Fixation under Ambient-Pressure Alkaline-Hydrothermal-Vent Conditions

Life, 2019
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.

Defined folding pattern of poly(rG) supports inherent ability to encode biological information. [PDF]

Biopolymers
Abstract The RNA World hypothesis posits that RNA can represent a primitive life form by reproducing itself and demonstrating catalytic activity. However, this hypothesis is incapable of addressing several major origin‐of‐life (OoL) questions. A recently described paradox‐free alternative OoL hypothesis, the Quadruplex (G4) World, is based on the ...

Quantifying the Origins of Life on a Planetary Scale [PDF]

, 2015
A simple, heuristic formula with parallels to the Drake Equation is introduced to help focus discussion on open questions for the origins of life in a planetary context. This approach indicates a number of areas where quantitative progress can be made on

Quantum Computing for Molecular Biology**

ChemBioChem, Volume 24, Issue 13, July 3, 2023., 2023
A road map for quantum computing in molecular biology with a potentially ground‐breaking quantum advantage is presented. Key concepts are introduced to connect the terminology of biology, chemistry, physics, and computer science that are all relevant for this transdisciplinary endeavor.

The Fuel Cell Model of Abiogenesis: A New Approach to Origin-of-Life Simulations [PDF]

Astrobiology, 2014
In this paper, we discuss how prebiotic geo-electrochemical systems can be modeled as a fuel cell and how laboratory simulations of the origin of life in general can benefit from this systems-led approach. As a specific example, the components of what we have termed the "prebiotic fuel cell" (PFC) that operates at a putative Hadean hydrothermal vent ...

Superconductivity mystery turns 25 [PDF]

Nature 576, 386-387 (2019), 2020
In 1994, an unconventional form of superconductivity was detected in strontium ruthenate. The discovery has shed light on the mechanism of unconventional superconductivity at high temperatures. "The great tragedy of Science [is] the slaying of a beautiful hypothesis by an [experimental] fact." - T.H. Huxley, Biogenesis and abiogenesis, (1884)
