Self‑replicating circular RNA persists in extreme environments: Insights from hot spring microbiomes
Although the genetic material of most living organisms is DNA, various self-replicating agents rely instead on RNA, including RNA viruses and viroids, which are infectious RNA molecules that are ...
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 ...
According to the RNA world hypothesis, life began when RNA molecules evolved the ability to make more copies of themselves. Now we have discovered an RNA molecule that is almost capable of this – it ...

A strand of RNA just 45 nucleotides long can copy its own complementary sequence in frozen conditions that may resemble early Earth, according to a study published in Science in early 2026. The ...
