Multi‐isotope (N, O, Ti, and Cr) study of C1 and CM‐like clasts—Probing unsampled C1 material

Meteoritics &Planetary Science, EarlyView.
Abstract A multi‐element isotope (N, O, Ti, and Cr) study was conducted on C1 and CM‐like clasts hosted in achondrites and chondrite breccias to understand the genesis of these chondritic clasts. The mineralogy, O, and N isotopes confirm that CM‐like clasts in howardites and polymict eucrites closely resemble CM chondrite‐like material.

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

Molecular 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

Molecular 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

Nations 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 ...
