Over the last few years, scientists and entrepreneurs have flocked to developing medicines that target RNA, the genetic blueprint that cells in our bodies use to make proteins. RNA has been in the ...

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 ...

The United States Food and Drug Administration has just approved the first-ever clinical trial that uses CRISPR-Cas13 RNA ...

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 ...

How does a cell know when it’s been damaged? A molecular alarm, set off by mutated RNA and colliding ribosomes, signals danger. When the sun shines on your skin, what does it hit? When it causes a ...

Federal investment in RNA vaccine research has supported nearly three decades of scientific work spanning infectious diseases, cancer, and vaccine development, but recent and proposed funding cuts ...

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 ...

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