Scientists have discovered ‘dark’ oxygen being produced at more than 13,000 feet below the ocean surface, challenging long-held assumptions about deep-sea ecosystems. In 2013, ocean scientist Andrew Sweetman observed a puzzling phenomenon while on a vessel in a remote part of the Pacific Ocean. His equipment showed that oxygen was being produced on the seabed, …

Global surveillance of antimicrobial resistance in food animals using priority drugs maps

2024-01-26 01:46 PM

This analysis is structured in five steps (Fig. 5a–e): (a) collection and extraction of epidemiological information from point prevalence surveys (PPS); (b) mapping distribution of resistance prevalence using three machine learning models; (c) ensembling predictions using Gaussian process stacked generalization; (d) mapping priority antimicrobials for surveillance; and (e) estimating prediction uncertainty of maps generated in steps …
