Volume measurement of microparticles using SEM photogrammetry and 3‐D reconstruction

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract In this paper, we introduce a method for volume measurement of microparticles that includes scanning electron microscope photogrammetry with 3‐D model construction. Our results show that our method limits the volume uncertainty to ±10%, which is a significant improvement compared to previous methods (which likely overestimated volume by 100 ...

Temporal Loss of Genome‐Wide and Immunogenetic Diversity in a Near‐Extinct Parrot

open access: yesMolecular Ecology, EarlyView.
ABSTRACT Loss of genetic diversity threatens a species' adaptive potential and long‐term resilience. Predicted to be extinct by 2038, the orange‐bellied parrot (Neophema chrysogaster) is a critically endangered migratory bird threatened by numerous viral, bacterial and fungal diseases.

Functional and Pangenomic Exploration of Roc Two‐Component Regulatory Systems Identifies Novel Players Across Pseudomonas Species

open access: yesMolecular Microbiology, EarlyView.
The Roc system represents a highly interconnected but incomplete network of two‐component regulatory systems involved in the virulence of Pseudomonas aeruginosa. Our work has enabled us to identify the missing RocA3 regulator, to propose new players in the system and to delineate their conservation between clades of the species.

‘The non‐dormant beast’: Antisemitism in communities of Russian nationalists on Vkontakte

open access: yesNations and Nationalism, EarlyView.
Abstract The article explores the specifics of Russian antisemitic discourse of recent years using the example of three nationalist communities on Vkontakte, the most popular Russian social networking site, by means of critical discourse analysis. The main strategies they employ to frame the Jews online are stereotyping Jews as ungrateful and greedy ...

The simplicity of physical laws

open access: yesNoûs, EarlyView.
Abstract Physical laws are strikingly simple, yet there is no a priori reason for them to be so. I propose that nomic realists—Humeans and non‐Humeans—should recognize simplicity as a fundamental epistemic guide for discovering and evaluating candidate physical laws.
