More than four billion years ago, Earth was a very different place. Pools of water froze and thawed in cycles, minerals shaped reactions, and molecules bumped into each other by chance. Out of this ...

The new findings strengthen the "RNA world" hypothesis that describes how the first life on Earth could have used RNA instead ...

New research shows how RNA, a key molecule for life, may have formed on early Earth using simple chemistry and materials delivered by asteroid impacts, linking space science with the origins of life ...

New experiments suggest RNA, life’s essential molecule, could have formed naturally on early Earth and even arrived from ...

Ask a friend what DNA is and, chances are, they have a general idea. Seventy years after scientists discovered the two-stranded helix, DNA (deoxyribonucleic acid) is widely understood as the keeper of ...

RNA Polymerase (shown in blue) moves across a template strand of DNA (shown in purple) and transcribes it into RNA (shown in red). But DNA damage blocks the RNA polymerase, causing it to stall and ...

Researchers say discoveries could expand the CRISPR toolbox and lead to more efficient, rapid diagnostic tools for detecting COVID-19, influenza, and RSV.
