Using new simulations, researchers discovered one part of RNA smoothly invades and displaces another part of the same RNA, enabling the structure to rapidly and dramatically change shape. Called ...

While great strides have been made in exploring the world of RNA, mysteries remain—and one approach to solving them is to look at what exactly a strand of RNA is doing in a cell in real time. At a ...

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 findings, published on 11 May ...
