Wiring up the brain's trillions of circuit connections is an enormous job performed by a huge crew of molecules. Among the less understood members are circular RNAs, transcripts from DNA that assume a ...

By examining genomic variation more closely, scientists can now identify new disease connections with greater speed and accuracy. For centuries, scientists have recognized that certain illnesses can ...

A team of scientists that included researchers from UCLA has discovered a novel mechanism of RNA regulation in embryonic stem cells. The findings are strong evidence that a specific chemical ...

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 ...

A bacterial protein helps to stop transcription -- the process of making RNA copies of DNA to carry out the functions of the cell -- by causing the cellular machinery that transcribes the DNA to pause ...

Ribosomal RNA (rRNA) is a type of molecule and a key building block of the ribosome, the cell's protein-making machinery. rRNA accounts for much of the RNA in a cell, and it's crucial for life.
