Scum of the Earth: A Hypothesis for Prebiotic Multi-Compartmentalised Environments

Life, 2021
Compartmentalisation by bioenergetic membranes is a universal feature of life. The eventual compartmentalisation of prebiotic systems is therefore often argued to comprise a key step during the origin of life.

Gypsum Gardens: Self‐Assembled Tubular Structures of Calcium Sulfate with Relevance for the Detection of Extraterrestrial Life

Angewandte Chemie International Edition, EarlyView.
Chemical gardens are self‐assembled architectures with “life‐like” morphologies that form in the absence of any biological activity. Here we show that such structures can also be obtained by contacting reservoirs of calcium and sulfate ions, under conditions that plausibly emulate those prevailing on early Mars.

In situ detection of boron by ChemCam on Mars [PDF]

, 2017
We report the first in situ detection of boron on Mars. Boron has been detected in Gale crater at levels Curiosity rover ChemCam instrument in calcium-sulfate-filled fractures, which formed in a late-stage groundwater circulating mainly in phyllosilicate-

Prebiotics: The Concept Revisited1, [PDF]

The Journal of Nutrition, 2007
A prebiotic is "a selectively fermented ingredient that allows specific changes, both in the composition and/or activity in the gastrointestinal microflora that confers benefits upon host well-being and health." Today, only 2 dietary nondigestible oligosaccharides fulfill all the criteria for prebiotic classification. The daily dose of the prebiotic is

Regulating Promiscuous Catalysis via Substrate‐Induced Transient Assembly

Angewandte Chemie International Edition, EarlyView.
We report a novel substrate‐induced transient co‐assembly between a short Lys‐rich peptide and Fmoc‐Gly‐OH. In the activated state, the assembly exhibits promiscuous catalytic activity through the rate enhancements of hydrolysis and C═N condensation reactions.

Hydrogel Composites and Their Potential Application in Animal Production and Health

Animal Research and One Health, EarlyView.
With emerging concerns about environmental contamination and safe animal production practices for increased animal welfare, research has increased in search of alternatives to promote sustainable production. The application of naturally derived hydrogels presents a great opportunity for exploration and application for animal production purposes ...
