Research highlights potential of often-overlooked water plant in mitigating food insecurity

An often-overlooked water plant that can double its biomass in two days, capture nitrogen from the air -; making it a valuable green fertilizer -; and be fed to poultry and livestock could serve as life-saving food for humans in the event of a catastrophe or disaster, a new study led by Penn State researchers suggests.

Study attributes West Nile virus expansion in Europe to climate change

West Nile virus is an emerging pathogen in Europe and represents a public health threat in previously non-affected European countries. Occurring in a cycle involving transmission between bird and mosquito species, this virus can be transmitted to humans by mosquitoes and induce West Nile fever.
