Storm clouds in the earth's
atmosphere are filled with diverse microbial life and organic chemicals,
according to a study published January 23 in the
open access journal PLOS ONE by Tina Šantl Temkiv
and colleagues from Aarhus University,
Discovery of bacteria that typically live on plants,
presumably swept into storm clouds by updrafts from earth,
suggests the atmosphere is a threat that can
connect distant eco systems. Researchers analyzed hailstones recovered in Slovenia from a
May 2009 storm.
of the bacterial species found can seed ice crystals that lead to rain and
snow, leading researchers to suspect the bacteruia could influence weather
