Chemists say they have solved a crucial problem in a theory of life’s beginnings, by demonstrating that RNA molecules can link short chains of amino acids together. The discovery “opens up vast and ...

The oldest RNA ever reported until now came from a 14,300-year-old “wolf” puppy frozen in permafrost. But when Mármol-Sánchez ...

Dr. Cech is a biochemist and the author of the forthcoming book “The Catalyst: RNA and the Quest to Unlock Life’s Deepest Secrets,” from which this essay is adapted. From E=mc² to splitting the atom ...

Bioengineers at the University of California San Diego have developed a powerful new technology that can map the entire network of RNA-protein interactions inside human cells—an achievement that could ...

Many writers grouse when an editor makes a change in a story, but the consequences of changing a single word usually aren’t that dire. Not so with genetic instructions for making proteins. Even a ...

Single-cell RNA transcriptomics allows researchers to broadly profile the gene expression of individual cells in a particular tissue. This technique has allowed researchers to identify new subsets of ...
