A study identifies a novel self-replicating circular RNA in hot springs, revealing unexpected diversity of RNA replicators, ...

One of the greatest mysteries of our planet is how a soup of lifeless chemicals transformed into the first living cell. There are several competing theories about where this happened, from frozen ...

Chemists have demonstrated how RNA (ribonucleic acid) might have replicated itself on early Earth -- a key process in the origin of life. Chemists at UCL and the MRC Laboratory of Molecular Biology ...

The relationship between RNA sequences and their resultant structures is central to understanding evolutionary processes and molecular robustness. Genotype–phenotype mapping studies reveal how subtle ...

DNA is the backbone of the genetic code so, logically, decoding and understanding the genetic sequence along with epigenetic modifications came first. Yet, RNA and the emerging field of ...

Prospects for understanding the origin of the RNA world / Gerald F. Joyce and Leslie E. Orgel -- Reading the palimpsest: contemporary biochemical data and the RNA world / Steven A. Benner ... [et al.] ...

Although the genetic material of most living organisms is DNA, various self-replicating agents rely instead on RNA, including RNA ...

Two University of Chicago scholars have been elected to the National Academy of Sciences, joining other scientists and researchers chosen in “recognition of their distinguished and continuing ...

Researchers updated the global catalogue of human-infective RNA viruses to 239 ICTV-recognised species, incorporating ...

A Western Australian biotech partnership is developing RNA-based therapies to treat type 2 diabetes by directly improving ...
