Glacier "Bleeds" Proof of Million-Year-Old Life-Forms

Gushing from a glacier, rust-stained Blood Falls contains evidence that microbes have survived in prehistoric seawater deep under ice for perhaps millions of years, a new study says. The colony of microscopic life-forms may have been trapped when Antarctica's then advancing Taylor Glacier reached into the ocean 1.5 to 4 million years ago.

What's more, the tiny organisms' feeding habits apparently give the falls their shocking color.  Photo: Photograph courtesy Benjamin Urmston via Science
