Scientists discover hidden layer of RNA that helps fine-tune how tightly DNA coils itself
Scientists have identified a previously unrecognized layer of the human genome. It’s built not ...
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 ...
Recent research showed that an artificially constructed RNA self-replicating system modeling primitive life at the origin of life evolved to become more prone to extinction under certain experimental ...
Cedars-Sinai scientists have created a new experimental drug called TY1 that helps the body repair damaged DNA and restore injured tissue. The discovery came from studying tiny molecular messages ...
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.
