Performance Evaluation of a Full‐Scale Anaerobic Internal Circulation Reactor Treating Calcium Rich Dairy Industry Wastewater

open access: yesWater and Environment Journal, EarlyView.
This study investigates the impact of calcium on the performance of a large‐scale internal circulation (IC) reactor treating calcium‐rich dairy wastewater. Excessive calcium concentrations (400‐600 mg L−1) resulted in calcification of the anaerobic sludge, reactor walls, and pipes, suggesting a 17% and 25% reduction in biogas and methane production ...

Update to the Taxonomic Outline of the Archaea and Bacteria and inclusion of the Taxonomic Notes into the Manual

open access: yesMajor Reference Works, Page 1-6.

Bergey's Manual of Systematics of Archaea and Bacteria (BMSAB) is a reference work aimed at undergraduates, graduate students, researchers, professors and experienced professionals at all levels. About a hundred new genera and 600+ new species have been described per year for each of the last 5 years.

Clumped Isotope Temperature Reconstruction Using Stalagmite Drip Cups

open access: yesRapid Communications in Mass Spectrometry, Volume 40, Issue 8, 30 April 2026.
ABSTRACT Rationale Application of clumped isotope palaeothermometry to speleothems (carbonate cave deposits, e.g., stalagmites and flowstones) has been restricted largely to subaqueous samples because of kinetic fractionation processes that occur during subaerial speleothem formation, which lead to erroneously high inferred temperatures.

Molecular bases of insect odorant receptor function: specificity and evolution

open access: yesBiological Reviews, Volume 101, Issue 2, Page 1036-1049, April 2026.
ABSTRACT Insect odorant receptors (ORs) are a class of chemoreceptors that insects use to detect volatile cues in their environment. In recent years, major advances in the field of structural biology have made it possible to obtain the first structures of insect ORs.
