NewsTiny tornadoes around leaves spread deadly plant pathogens
A new study is the first to analyze plant spore dispersion at its source, where rain droplets shake flexible leaves to initially disperse pathogens.

NewsModified phage DNA can kill deadly pathogens
DNA modified from a bacteriophage and put inside Pseudomonas aeruginosa was found to bypass the pathogen’s defense mechanisms to assemble into virions, which sliced through the bacterium’s cell to kill it.

NewsFungal-rich soil may improve green roofs
Active management of green roof mycorrhizal fungi accelerates soil development faster than if mycorrhizal fungal communities are left to passively reestablish on their own, a new study shows.
