Halloween Science: Bacteria of the Living Dead

DISCOVER Magazine: "A team of scientists melted five samples of ice from Antarctica in hopes of reviving the oldest known frozen bacteria—millions of years older than any previously brought to life. And, in fact, the bacteria, ranging in age from 100,000 to a stunning 8 million years old, came groaning back in the culture flask. The younger the bacteria, the more quickly the resurrection occurred. It took the younger bacteria just seven days to reproduce; the oldest samples took up to 10 times as long."
