Driving forces in the origins of life. [PDF]
Open Biol, 2021 What were the physico-chemical forces that drove the origins of life? We discuss four major prebiotic 'discoveries': persistent sampling of chemical reaction space; sequence-encodable foldable catalysts; assembly of functional pathways; and encapsulation

The Grayness of the Origin of Life [PDF]
Life, 2021 In the search for life beyond Earth, distinguishing the living from the non-living is paramount. However, this distinction is often elusive, as the origin of life is likely a stepwise evolutionary process, not a singular event. Regardless of the favored origin of life model, an inherent “grayness” blurs the theorized threshold defining life.

Frontiers in Chemistry, 2021 Using the radicals generated during pH oscillations, a semibatch pH oscillator is used as the chemical fuel and engine to drive polymerization induced self-assembly (PISA) for the one-pot autonomous synthesis of functional giant vesicles.

The eco-evolutionary origins of life.
Evolution; international journal of organic evolution, 2023 The origin of life remains one of the greatest enigmas in science. The immense leap in complexity between prebiotic soup and cellular life challenges historically "chemistry-forward" and "biology-backwards" approaches.

Origins of Life: Chemistry and Evolution [PDF]
, 2023 Our understanding of the origins of life will be enhanced if models and their predictions are clearly understood and explicitly articulated. Here we outline two distinct models that are currently used to explain the origins of life.

A Constructive Way to Think about Different Hydrothermal Environments for the Origins of Life. [PDF]
Life (Basel), 2020 The question of where life originated has been contentious for a very long time. Scientists have invoked many environments to address this question. Often, we find ourselves beholden to a location, especially if we think life originated once and then ...

Evolution of Realistic Organic Mixtures for the Origins of Life through Wet–Dry Cycling
Sci, 2022 One of the challenges in understanding chemical evolution is the large number of starting organics and environments that were plausible on early Earth. Starting with realistic organic mixtures and using chemical analyses that are not biologically biased,

Frontiers in Chemistry, 2021 Computing with molecules is at the center of complex natural phenomena, where the information contained in ordered sequences of molecules is used to implement functionalities of synthesized materials or to interpret the environment, as in Biology.

Annual Review of Genetics, 1974 The origin of life is in a sense a genetic problem, for, as H. J. Muller pointed out many years ago, the essential attribute that identifies living matter is its capacity to replicate itself and its variants (1). Because this uniquely biological property has its physical basis in proteins and nucleic acids, the goal of modern work on the origin of life
