Scientists may have found a clue to one of the biggest mysteries surrounding the origin of life: how fragile RNA molecules could gather and survive before cells existed. New research shows that RNA is ...

Comparative effectiveness in METex14 NSCLC: Outcomes from a propensity score–based analysis of 8 pooled real-world datasets (the TOGETHER study).

Scientists have identified a previously unrecognized layer of the human genome. It's built not from DNA's usual building blocks, but from small fragments of RNA embedded directly inside it. Georgia ...

On the left are three forms of the same RNA molecule, which is stabilised into a single form (on the right) by mitoxantrone. Ribonucleic acids (RNAs) serve as messengers between DNA and protein ...

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 ...

There have been many important discoveries along the path to what we know today about RNA, or ribonucleic acid—a molecule found in every living cell that helps carry and interpret genetic instructions ...

CRISPR’s rise from obscure bacterial defense system to molecular scalpel has always hinged on one small component: the guide RNA. For years, that guide RNA—meticulously designed, modified, and ...

RNA and DNA are chemical cousins. But one tiny difference between them (an extra oxygen atom repeated along RNA’s backbone) ...
