The new record pushes RNA preservation back 25,000 years.
Scientists have sequenced RNA from a woolly mammoth that lived 39,000 years ago, setting a new record for the oldest RNA ever recovered. The study, published in Cell, pushes the previous record (held by a 14,300-year-old Siberian puppy) back by an extraordinary 25,000 years, opening a new window into ancient genetics and how extinct species functioned.
