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. The finding was detailed in a recent study published in the journal PLOS Genetics.
