Researchers at the Department of Cell and Molecular Biology, Karolinska Institutet have captured the first detailed molecular snapshots of human polynucleotide phosphorylase (hPNPase) in action, ...

Whether you turn red when drinking alcohol, dislike certain smells, or metabolize drugs differently from others, the ...

We have long struggled to determine how the first living organisms on Earth came together. Now, surprising evidence hints ...

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

The DNA inside of living organisms is packed with information, so much so that it's hard to search genetic databases, but there may be a solution.

Researchers have sequenced the oldest RNA ever recovered, taken from a woolly mammoth frozen for nearly 40,000 years. The RNA reveals which genes were active in its tissues, offering a rare glimpse ...

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 ...

Scientists have sequenced the oldest-ever RNA from a 39,000-year-old woolly mammoth named Yuka, whose remains were found frozen on a bluff in northeastern Siberia. The discovery contradicts the ...

Researchers from Stockholm University have—for the first time ever—managed to successfully isolate and sequence RNA molecules from Ice Age woolly mammoths. These RNA sequences are the oldest ever ...

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 ...

In 2010 Yukaghir hunters found the nearly intact carcass of a young woolly mammoth frozen in the northern Siberian permafrost. With its reddish-brown fur still clinging to its skin, the dog-sized calf ...
