There are plenty of unanswered questions about the origin of life on Earth. But the research community has largely reached consensus that one of the key steps was the emergence of an RNA molecule that ...

According to the RNA world hypothesis, life began when RNA molecules evolved the ability to make more copies of themselves. Now we have discovered an RNA molecule that is almost capable of this – it ...

Scientists at Rutgers University–Newark have developed a first-of-its-kind RNA-based nanotechnology that assembles itself inside living human cells and can be programmed to stop propagation of harmful ...

QIMR Berghofer scientists have discovered a cancer-fighting RNA molecule that could hold the key to a new way of treating the most common form of breast cancer. The team are developing their findings ...

An innovative three-color method for capturing images of mRNA inside live mammalian cells has been developed by UMass Amherst chemists. Because RNA is both incredibly important to human life and ...

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 ...

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 ...

Some 39,000 years ago, a woolly mammoth died in present-day Siberia, destined to be blanketed by ice and permafrost that would end up preserving its body — even down to the hair and muscle. Subscribe ...

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 ...
