High-throughput assays to identify archaea-targeting nitrification inhibitors

Frontiers in Plant Science
Nitrification is a microbial process that converts ammonia (NH3) to nitrite (NO2-) and then to nitrate (NO3-). The first and rate-limiting step in nitrification is ammonia oxidation, which is conducted by both bacteria and archaea.

Impact of ENSO on Nitrous Oxide Emissions in the Eastern Tropical Pacific

Global Biogeochemical Cycles, Volume 40, Issue 3, March 2026.
Abstract Nitrous oxide (N2O ${\mathrm{N}}_{2}\mathrm{O}$) is a powerful greenhouse gas, with the ocean contributing ∼4.2 Tg N y−1 to global N2O ${\mathrm{N}}_{2}\mathrm{O}$ emissions. The Eastern Tropical Pacific (ETP) is a hotspot of N2O ${\mathrm{N}}_{2}\mathrm{O}$ emissions due to high N2O ${\mathrm{N}}_{2}\mathrm{O}$ production under low‐oxygen ...

Acidification Stimulates N2O Production by Oceanic Nitrifying Bacteria

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 3, March 2026.
Abstract Recent studies have shown changes in the production rates of nitrous oxide (N2O) in aerobic seawater in response to ocean acidification (OA). Understanding how N2O production responds to OA is crucial because N2O is a strong greenhouse gas and stratospheric ozone‐depleting substance emitted from the ocean.

Recommendations for Stress Ulcer Prophylaxis in Critically Ill Adults: A Contextualized Clinical Practice Guideline From the Saudi Critical Care Society and the Scandinavian Society of Anaesthesiology and Intensive Care Medicine, Endorsed by the Kuwait Anesthesia and Critical Care Society

Acta Anaesthesiologica Scandinavica, Volume 70, Issue 3, March 2026.
ABSTRACT Background Critically ill adults are at risk for stress‐related upper gastrointestinal bleeding (UGIB). Regional variations in gastrointestinal bleeding incidence, infection epidemiology, formulary access, and the relative value placed on bleeding versus infection outcomes by patients and clinicians necessitate contextualized recommendations ...
