Chemical evolution and life [PDF]
BIO Web of Conferences, 2015 In research on the origins of life, the concept of “chemical evolution” aims at explaining the transition from non-living matter to living matter.

Life, 2022 The origin of biopolymers is a central question in origins of life research. In extant life, proteins are coded linear polymers made of a fixed set of twenty alpha-L-amino acids.

Life, 2022 Non-communicable diseases are those conditions to which causative infectious agents cannot readily be assigned. It is increasingly likely that at least some of these conditions are due to the breakdown of the previously mutualistic intestinal microbiota ...

Gastrointestinal Disorders, 2022 While the importance of the intestinal microbiome has been realised for a number of years, the significance of the phrase microbiota–gut–brain axis is only just beginning to be fully appreciated.

Thioesters provide a plausible prebiotic path to proto-peptides
Nature Communications, 2022 One of the early processes enabling the origins of life is thought to be the condensation of building blocks into oligomers and polymers. In this article, the authors report the synthesis of thiodepsipeptides and HS-peptides under mild temperatures and ...

Life, 2022 It is increasingly likely that many non-communicable diseases of humans and associated animals are due to the degradation of their intestinal microbiomes, a situation often referred to as dysbiosis.

Microbiome–Gut Dissociation: Investigating the Origins of Obesity
Gastrointestinal Disorders, 2021 The reduction of excessive weight remains a major public health challenge, with control currently limited to a calorie reduction strategy. Currently, attempts are being made at revisiting the fibre hypothesis based on the African studies of Denis Burkitt,

THE CHEMICAL EVOLUTION OF PHOSPHORUS [PDF]
The Astrophysical Journal, 2014 Phosphorus is one of the few remaining light elements for which little is known about its nucleosynthetic origin and chemical evolution, given the lack of optical absorption lines in the spectra of long-lived FGK-type stars. We have identified a P I doublet in the near-ultraviolet (2135/2136 A) that is measurable in stars of low metallicity.

Galactic Chemical Evolution [PDF]
Publications of the Astronomical Society of Australia, 2003 AbstractThe primary present-day observables upon which theories of galaxy evolution are based are a system’s morphology, dynamics, colour, and chemistry. Individually, each provides an important constraint to any given model; in concert, the four represent a fundamental (intractable) boundary condition for chemodynamical simulations.
