This story is part of a larger series on viroids and virusoids, small infectious RNAs. It is also the fifth installment in a series on hepatitis D virus, a virusoid-like pathogen that causes serious ...

Researchers at the University of Tokyo have created an RNA molecule that can not just replicate, but “evolve” into a diverse range of more complex molecules. This find could plug a major gap in the ...

The discovery of catalytic RNA transformed our understanding of life's beginnings. Clare Sansom explores how the RNA world ...

They say that change takes time. Well, that's not the case for RNA. The small biological molecule acts like a switchboard operator, capable of changing its shape every few milliseconds so it can ...

Chemists at UCL and the MRC Laboratory of Molecular Biology have demonstrated how RNA (ribonucleic acid) might have replicated itself on early Earth – a key process in the origin of life. Scientists ...

HIV replication in the human body requires that specific viral RNAs be packaged into progeny virus particles. A new study has found how a small difference in the RNA sequence can allow the viral RNA ...

Replicate Bioscience emerged from stealth mode on Wednesday with an ambitious vision for how RNA treatments can combat cancer, autoimmune disease and inflammatory disorders. It’s a goal that seems ...

This article is part of a series on viroids. The first, which can be read here, gave an overview of what viroids are and how they replicate. The second article described the plant host range of ...

Replicate Bioscience emerged from stealth mode this month with an ambitious vision for how RNA treatments can combat cancer, autoimmune disease and inflammatory disorders. It’s a goal that seems more ...
