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 ...

Liquid brine veins, where RNA molecules can replicate, surround solid ice crystals in water ice, as seen with an electron microscope. Chemists at UCL and the MRC Laboratory of Molecular Biology have ...

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 ...

A University of Maryland, Baltimore County (UMBC) study, published in Nature Communications, uncovers how enteroviruses—including those causing polio, myocarditis, encephalitis, and the common ...

For 400 million years, a leading hypothesis claims, Earth was an “RNA World,” meaning that life must’ve first replicated from RNA before the arrival of proteins and DNA. Unfortunately, scientists have ...
