Neurons have a "hibernation mode." Scientists discover how brain cells use RNA tentacles to lock their protein factories together to survive when energy is low.

Two separate laboratory breakthroughs have produced RNA molecules that can build copies of themselves or assemble functional structures without any help from proteins or DNA. These results offer the ...

Ribosomes, the cell's protein-making factories, consume large amounts of energy as they build the proteins that keep cells alive and functioning. When cells experience stress—such as lack of nutrients ...

RNA in cells performs an astounding number of functions. Messenger RNA carries the sequences of active genes to cellular machinery that turns it into proteins. And transfer RNA molecules are an ...

Researchers are embarking on the RNA equivalent of the Human Genome Project, including sequencing all the chemical ...

RNA is a central biological macromolecule, now widely harnessed in medicine and nanotechnology. Like proteins, RNA function often depends on its precise three-dimensional structure. A recent study ...

RNA, or ribonucleic acid, is a short-lived molecule copied from DNA that enables cells to use genetic information. Specific DNA sequences are copied into RNA, which then delivers these instructions to ...

A study of a bacteria commonly used in dairy fermentation revealed how organized RNA helixes, called riboswitches, can combine different signals to keep gene expression in check. Researchers from the ...

An experimental RNA therapy from Avidity Biosciences has early clinical trial results showing it reduced by half the expression of a gene at the root of a rare, inherited form of muscular dystrophy ...
