Cells in our bodies produce RNA based on genetic information stored in DNA, and RNA serves as a blueprint for making proteins ...

A Japanese team, which detected DNA and RNA bases in this asteroid's samples, also shared a disclaimer.

DNA-nanoparticle motors are exactly as they sound: tiny artificial motors that use the structures of DNA and RNA to propel motion by enzymatic RNA degradation. Essentially, chemical energy is ...

A team at UT Southwestern Medical Center has identified a structural trick that lets viruses translate their genetic code inside human cells, even when that code is riddled with “bad” codons the host ...

As aging progresses, the quality of DNA and proteins inside cells declines, known to be the cause of various degenerative diseases. However, the connection between aging and RNA has remained largely ...

Bioengineers at the University of California San Diego have developed a powerful new technology that can map the entire network of RNA-protein interactions inside human cells - an achievement that ...

Researchers have revealed a new mechanism underlying how spatial distance between specific regions of DNA is linked to bursts of gene activity. Using advanced cell imaging techniques and computer ...

Medical scientist Eduardo Marbán – then at Johns Hopkins and now Cedars-Sinai – found that heart progenitor cells also have a special mechanism where they send out sacs, known as exosomes, which carry ...

A forested hill and clouds are in the background of an image of a shallow pool of steaming water, with the ground underneath colored in shades of beige, red, and brown. Life may have first emerged in ...

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 ...
