Paging Michael Crichton

Japanese clone mouse from frozen cell, aim for mammoths: "Japanese scientists said Tuesday they had created a mouse from a dead cell frozen for 16 years, taking a step in the long impossible dream of bringing back extinct animals such as mammoths.

Scientists at the government-backed research institute Riken used the dead cell of a mouse that had been preserved at minus 20 degrees Celsius (minus 4 degrees Fahrenheit) -- a temperature similar to frozen ground.

The scientists hope that the first-of-a-kind research will pave the way to restore extinct animals such as the mammoth."
