Scientists
have discovered a worm that managed to stretch
its short life expectancy — by tens of thousands of
years. A tiny roundworm was revived after it was
frozen in Siberian permafrost 46,000 years ago, when Neanderthals still walked the Earth. The worm, a previously unknown species of nematode, survived after entering a dormant state known as cryptobiosis, during which the animal doesn’t eat and lacks a metabolism. -National Public Radio |
