All the essential ingredients to make the DNA and RNA underpinning life on Earth have been discovered in samples collected from the asteroid Ryugu, scientists said Monday. The discovery comes after ...

The RNA world hypothesis posits that molecules made up of ribonucleic acids (RNA) are responsible for kickstarting evolution ...

EMBL researchers created SDR-seq, a next-generation tool that decodes both DNA and RNA from the same cell. It finally opens access to non-coding regions, where most disease-associated genetic variants ...

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) ...

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 ...

We’re celebrating 180 years of Scientific American. Explore our legacy of discovery and look ahead to the future. In 1957, just four years after Francis Crick and other scientists solved the riddle of ...

Sunburn has traditionally been attributed to UV-induced DNA damage. However, a new study reveals that RNA, another vital cellular molecule, plays a major role in triggering acute sunburn reactions.

Scientists have identified the likely geological and environmental conditions that fostered the development of life as we know it on planet Earth. This setting is a place where the basic parts of ...
