Sulfites and sulfates formed by weathering of early martian carbonates in a sulfur dioxide-bearing atmosphere.

Despite ample evidence that extensive water-rock interactions occurred under a CO-dominated atmosphere on early Mars, carbonate minerals are relatively rare at the surface. One possibility to explain this scarcity is that carbonates were initially abundant, but were later destroyed when atmospheric conditions changed, particularly as a result of volcanism releasing large volumes of sulfur dioxide SO into the atmosphere. However, despite some early theoretical and experimental results, no study has investigated the stability of the most common carbonates (Ca, Mg and Fe) in the presence of abundant SO gas.

Evaluation of a Tetracycline-Resistant Enumeration Method for Correctly Classifying in Environmental Waters in Kentucky, USA.

The global concern over antimicrobial resistance (AMR) and its impact on human health is evident, with approximately 4.95 million annual deaths attributed to antibiotic resistance. Regions with inadequate water, sanitation, and hygiene face challenges in responding to AMR threats.
