In 2010, tusk hunters scouring a riverbank near Siberia’s Arctic coast discovered the mummy of a juvenile mammoth. The animal, nicknamed “Yuka” after the nearby village of Yukagir, had been frozen for ...

Scientists have recovered ancient molecules of RNA from a juvenile mammoth named Yuka, who died 40,000 years ago in what is now Siberia. These biological remnants are providing insight into the last ...

It was 2012 when Love Dalén, a paleogeneticist at Stockholm University, first laid eyes upon a special specimen on a lab table in eastern Siberia. "Our Russian collaborators said, 'Come here into this ...

In the final moments of Yuka the woolly mammoth’s life, he may have been trying to outsprint a cave lion. Yuka’s hind legs bear scratches — and in his muscle tissue, scientists have detected molecular ...

A woolly mammoth that was frozen in the Siberian permafrost for nearly 40,000 years has yielded the world’s oldest RNA. The specimen, found in 2010 and nicknamed Yuka, is regarded as the ...

Science equipment is displayed in a lab at the University at Albany’s RNA Institute. The institute is getting a $50 million expansion to make space for more research and to get discoveries ready for ...

Summary: Living longer doesn’t always mean living healthier, and researchers are exploring how diet can extend healthspan. A study in worms shows that specific dietary RNA molecules protect cells from ...

Researchers demonstrated how amino acids could spontaneously attach to RNA under early Earth-like conditions using thioesters, providing a long-sought clue to the origins of protein synthesis. This ...

We’re celebrating 180 years of Scientific American. Explore our legacy of discovery and look ahead to the future. In 1957, just four years after Francis Crick and other scientists solved the riddle of ...

In late July 2025, a rumor spread widely across social media platforms that billionaire investor Bill Gates received approval to "secretly" spray synthetic RNA on food crops in the United States. One ...

In living organisms today, complex molecules like RNA and DNA are constructed with the help of enzymes. So how did these molecules form before life (and enzymes) existed? Why did some molecules end up ...
