Story summary

Scientists extracted the oldest RNA from a woolly mammoth named Yuka who died nearly 40,000 years ago in Siberia.
The finding was published on November 14 in the journal Cell.
The study identifies messenger RNA linked to muscle contraction and metabolic regulation, and microRNA that regulates gene expression.
Researchers say the findings could inform understanding of ancient viruses and de-extinction for species like woolly mammoths.
