The oldest RNA ever reported until now came from a 14,300-year-old “wolf” puppy frozen in permafrost. But when Mármol-Sánchez ...

Researchers have successfully sequenced the oldest RNA ever recovered from the remains of a woolly mammoth named Yuka, who ...

Scientists examine the mummified remains of a 39,000-year-old mammoth nicknamed Yuka, whose tissue yielded ancient RNA in a ...

Mármol and his colleagues extracted RNA sequences from the muscles and skin of 10 permafrozen woolly mammoth specimens found across Northeastern Siberia. Analysis of one specimen, a juvenile mammoth ...

BUFFALO, N.Y. — The RNA world theory suggests that life on Earth began with RNA molecules that copied themselves. It’s believed this self-replication eventually gave rise over millions of years to DNA ...

Hyperthermophilic archaea are true survival experts. They thrive in boiling hot springs and deep-sea vents—environments ...

Researchers seeking to understand how life may have emerged from Earth’s primordial soup have found an interesting behavior of ribonucleic acid (RNA), which they suggest could have given way to ...

Obelisks—tiny RNA circles with protein-coding genes—have been found in the human microbiome, revealing a hidden RNA universe ...
