Hydrothermal origin of metabolic phosphorylation

The FEBS Journal, EarlyView.
Serpentinizing hydrothermal vents are candidate sites for biochemical origins. They generate extremely reducing conditions, depositing phosphite (HPO32−) and transition metals, including palladium, in the native (zero‐valent) state. Schlikker et al.

UbiB proteins mediate an ATP‐dependent decarboxylation step in bacterial ubiquinone biosynthesis

The FEBS Journal, EarlyView.
UbiB proteins are atypical protein kinase‐like enzymes essential for ubiquinone biosynthesis. Here, we demonstrate that bacterial UbiB proteins catalyze the O2‐dependent decarboxylation of ubiquinone precursors, a process linked to their ATPase activity.

Regenerative wheat management: The relative effects of farm practices on the biodiversity of invertebrates

Insect Conservation and Diversity, EarlyView.
Wheat in North America harbours a diverse insect community (565 morphospecies were identified in this study), and pests represented <7% of specimens collected. Regenerative wheat management promoted insect diversity without increasing pest populations.

Fragmented grasslands in different landscape structures provide different opportunities for cavity‐nesting Hymenoptera

Insect Conservation and Diversity, EarlyView.
Grassland fragmentation effects on cavity‐nesting Hymenoptera are habitat‐specific. Isolated sand steppe fragments are associated with higher brood‐cell abundance. In loess steppes, higher flower frequency increases bee brood‐cell production and parasitoid activity. Abstract The global decline in insects threatens ecosystem functioning, but the drivers

Outcome of Calcium Silicate Sealer‐Based Obturation in Root Canal Retreatment: A CBCT‐Based Prospective Cohort Study

International Endodontic Journal, EarlyView.
ABSTRACT Background Calcium silicate sealers (CSS) have become the dominant approach to root canal obturation in many specialist practices, yet evidence on their performance in nonsurgical retreatment is sparse and CBCT‐based assessment remains uncommon.
