RNA is a central biological macromolecule, now widely harnessed in medicine and nanotechnology. Like proteins, RNA function often depends on its precise three-dimensional structure. A recent study ...

SANTA CRUZ, CA — Researchers at the University of California, Santa Cruz, have determined the three-dimensional structure of an RNA enzyme, or “ribozyme,” that carries out a fundamental reaction ...

Researchers have now uncovered the 3D structure of the RNA enzyme SAMURI. Their study provides insights into the development of ribozymes and the evolution of catalytically active RNA. Researchers led ...

Researchers at Aarhus University have built a microscopic needle from DNA that can punch through a cell’s outer membrane and ...

The Nature Index 2025 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...

Atlanta—ACS Spring 2026, a meeting of the American Chemical Society, began with a flurry of talks early Sunday morning. During a session hosted by the Division of Biochemistry and Chemical Biology ...

Ribonucleic acids (RNAs) serve as messengers between DNA and protein production, and perform a wide variety of regulatory functions across different cellular processes. This makes them an interesting ...

Scientists may have a step forward in understanding how life on our planet came to exist. The mystery of how tiny molecules of RNA came to be enclosed within membranes, forming the very first cells, ...

With AI, it's now possible for researchers to predict the three-dimensional structures of proteins directly from their amino-acid sequences. But what biologists really want to predict, says Columbia ...

Before RNA and after : geophysical and geochemical constraints on molecular evolution / Stephen J. Mojzsis, Ramanarayanan Krishnamurthy, and Gustaf Arrhenius -- Prospects for understanding the origin ...

This image illustrates the chemical structure of a purine molecule, highlighting the numbering of the carbon and nitrogen atoms. The purine structure consists of a pyrimidine ring (positions 1 to 6) ...
