Survey finds epidemiologists believe viral and mosquito-borne pathogens are priority concerns for disease outbre
A new survey reveals that infectious disease experts point to viral pathogens and mosquito-borne pathogens as likely to spark outbreaks as humans, animals and viruses overlap; and new viruses are as concerning as changes to existing viruses.

The rise of microbial cheaters in iron-limited environments
Competition and cooperation are fundamental forces that govern the evolutionary and ecological dynamics among species. The balance between these forces varies across ecological contexts, with some environments favoring cooperative behaviors that promote mutual benefit, while others reward competitive strategies that maximize individual fitness. Among microbial communities, chemicals ...
