Recent research sampling the upper troposphere has uncovered a diverse array of microbial species, including some human pathogens, raising concerns about the global transport of potentially harmful organisms. While many of the microbes were found to be dead, having succumbed to the cold temperatures, increased radiation, and lack of nutrients, others proved surprisingly resilient. These … Continue reading Microbes Found in Earth’s Upper Troposphere Suggest Potential for Long-Distance Pathogen Travel
