You may not want to eat the snow.
Scientists have discovered something that will make many people think twice about lapping up those beautiful white snowflakes - they're often held together by bacteria.
"Bacteria are by far the most active ice nuclei in nature," said Brent Christner, an assistant professor of biological sciences at Louisiana State University.
The bacteria roaming around in the atmosphere are largely the kind that form on the surface of plants and poses scant danger to humans.
Still, Christner's findings, which were reported in yesterday's edition of the journal Science, are the first evidence that live bacteria plays a big role in the creation of snowflakes as well as raindrops.
