Scum of the Earth
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. Compartments may...
Proposed energy-metabolisms cannot explain the atmospheric chemistry of Venus
Abstract: Life in the clouds of Venus, if present in sufficiently high abundance, must be affecting the atmospheric chemistry. It has been proposed that abundant Venusian life could obtain energy from its environment using three...
Do Olivine Crystallization Temperatures Faithfully Record Mantle Temperature Variability?
Abstract: Crystallization temperatures of primitive olivine crystals have been widely used as both a proxy for, or an intermediate step in calculating, mantle temperatures. The olivine‐spinel aluminum‐exchange thermometer has...
Origin of Life's Building Blocks in Carbon- and Nitrogen-Rich Surface Hydrothermal Vents.
There are two dominant and contrasting classes of origin of life scenarios: those predicting that life emerged in submarine hydrothermal systems, where chemical disequilibrium can provide an energy source for nascent life; and...

Oliver Cromwell and the People of God
DL Smith
Jul 01, 2019
On 21 April 1657, in one of the speeches to Parliament’s representatives in which he meditated on their offer of the kingship, Oliver Cromwell offered these words of praise for those who had framed the Humble Petition and...
DFENS
Abstract: In order to reconcile petrological and geophysical observations of magmatic processes in the temporal domain, the uncertainties in diffusion timescales need to be rigorously assessed. Here, we present a new diffusion...
The evolution of the Galápagos mantle plume.
Caroline R Soderman, Oliver Shorttle, Esteban Gazel, Dennis J Geist, Simon Matthews, Helen M Williams
Apr 09, 2023
The lavas associated with mantle plumes may sample domains throughout Earth's mantle and probe its dynamics. However, plume studies are often only able to take snapshots in time, usually of the most recent plume activity...
Hydroxide Salts in the Clouds of Venus
Paul B. Rimmer, Sean Jordan, Tereza Constantinou, Peter Woitke, Oliver Shorttle, Richard Hobbs, Alessia Paschodimas
Jul 28, 2021
Abstract: The depletion of SO2 and H2O in and above the clouds of Venus (45–65 km) cannot be explained by known gas-phase chemistry and the observed composition of the atmosphere. We apply a full-atmosphere model of Venus to...
Problem formulation for theorizing at the frontier
Ostensibly, the evolving science of strategic management is geared towards addressing vexing
managerial problems. In practice, however, scholars in the field have a marked tendency to formulate problems to fit existing...

Non-invasive technical investigation of english portrait miniatures attributed to Nicholas Hilliard and Isaac Oliver
This study presents the results of the technical investigation carried out on several English portrait miniatures painted in the 16th and 17th century by Nicholas Hilliard and Isaac Oliver, two of the most famous limners...
