Snowflakes and raindrops have a surprise inside - bacteria.
Researchers at Louisiana State University in Baton Rouge found that sky-high bacteria, typically in harmless varieties, spurs creation of snowflakes and raindrops.
Snow and rain usually forms in cold conditions high in the sky. However, the moisture needs some kind of particle (called ice nucleator) to cling to […]
