Persistent Atmospheric and Ecosystem Impacts of Enteric Methane Emissions from Intensive Livestock Production Systems
Abstract: Enteric methane emissions from intensive livestock production systems exert a significant long-lasting influence on atmospheric stability and ecosystem integrity. Recent observations confirm that global methane emissions continued to rise through the early 2020s, with total emissions exceeding 620 teragrams per year by 2024, driven by expanding ruminant production and associated feed systems. Anthropogenic sources accounted for more than 330 teragrams per year, reflecting sustained growth in agricultural and fossil fuel …

The Ames Test in Twenty-first Century
Abstract: Since the 19th century, industrial development has increased exposure to mutagens and possible carcinogens. In order to avoid these health risks, several techniques have been developed to recognize genotoxins. In the 1970s, Dr. Bruce Ames and colleagues, studying the histidine operon of Salmonella typhimurium, observed that histidine (−) auxotroph mutants were reverted to histidine (+) upon exposure to a mutagen. The researchers further observed that known carcinogens were mutagenic to …
