Two separate laboratory breakthroughs have produced RNA molecules that can build copies of themselves or assemble functional structures without any help from proteins or DNA. These results offer the ...

Add Yahoo as a preferred source to see more of our stories on Google. In 1957, just four years after Francis Crick and other scientists solved the riddle of DNA’s structure—the now famous double helix ...

Scientists discover QT45, a self-replicating RNA molecule, offering insights into the origins of life on Earth.

Although there are striking differences between the cells that make up your eyes, kidneys, brain and toes, the DNA blueprint for these cells is essentially the same. Where do those differences come ...

With big pharma signalling interest in novel RNA-targeted approaches, the term “druggable” is being redefined as technology ...

The natural RNAi mechanism can be directed by either short interfering RNA (siRNA) or microRNA (miRNA). 1 There are four key steps in the RNAi pathway. When miRNA acts as the guide for RNAi, only a ...

40,000-year-old RNA from permafrost-preserved tissue was recovered from a mammoth specimen known as Yuka. Molecular evidence from Yuka revealed a correction to the original assumption about Yuka’s sex ...

People are still debating whether the mRNA from COVID-19 vaccines remains in the body longer than it should. Some say it lingers and causes harm, others say that idea just doesn’t hold up. A new ...

Reduce amplification bias caused by variable miRNA abundance using automated PCR normalization for NEXTFLEX small RNA sequencing workflows.

In the quest for RNA biomarkers indicative of fruit maturity, a cost-effective, reliable workflow is crucial. Accurate harvest timing is critical for shelf life and apple quality, but at present, ...
