Scientists have identified a microbe capable of interpreting a single piece of genetic code in two completely different ways, breaking a fundamental rule in molecular biology.

How life begins remains an unsolved question. One key component might be RNA, a molecular cousin of DNA found in every form of life on Earth, and now scientists say they have shown how it could have ...

Researchers uncovered a microbe that treats one stop codon as both a termination signal and an amino-acid instruction, revealing surprising genetic flexibility that may inspire new ways to influence ...

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 ...

Pfizer’s mRNA flu vaccine outperformed the standard flu shot in a Phase 3 clinical trial, according to results published Wednesday in the New England Journal of Medicine. The vaccine uses the same ...

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 ...

WASHINGTON, Nov 14 (Reuters) - Scientists have recovered the oldest-known RNA, a molecule necessary for most biological functions, from a woolly mammoth that inhabited Siberia about 39,000 years ago, ...

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 ...
