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.

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 ...

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 ...

A 45-nucleotide strand of RNA can now synthesize both its mirror-image complement and a copy of itself, bringing scientists ...

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 ...

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

Contrary to historic understanding of RNA’s longevity in cells, some RNAs can persist in cells throughout the life of an organism. Lead authors, Martin Hetzer, PhD, president of the Institute of ...

A chemical modification in the HIV-1 RNA genome whose function has been a matter of scientific debate is now confirmed to be key to the virus's ability to survive and thrive after infecting host cells ...

Add Yahoo as a preferred source to see more of our stories on Google. In 1957, just four years after Francis Crick and other scientists solved the riddle of DNA’s structure—the now famous double helix ...

By Hugo Francisco de Souza Emerging research suggests reversible RNA editing mechanisms may influence heart disease biology while opening new avenues for biomarkers and next-generation cardiovascular ...
