“Miracle” Microbes Thrive at Earth’s Extremes

For the past 30 years scientists have scoured the most inhospitable environments on Earth searching for life. Just about everywhere researchers look, they find it thriving in microscopic form.

These organisms, known as extremophiles, snuggle up to scalding hydrothermal vents in the Pacific Ocean. They cling to ice in Antarctica. They burrow in the high deserts of Chile and wallow in salty lake beds of East Africa.
