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 ...

Omics technologies have enabled researchers to study the molecular functions of human tissues. But some tissues—like the brain—are harder to access than others. Because of the limited access to living ...

When the Nanog gene (green region) is inactive, one of the three enhancer regions is spatially far away. When active, the same enhancer region makes close contact, interacting with the other enhancers ...

DNA and RNA epigenetics, once thought to be separate, have now been found to work together to fine-tune gene expression. When you purchase through links on our site, we may earn an affiliate ...

A research team at Florida State University's Institute of Molecular Biophysics and Department of Chemistry and Biochemistry ...

Northwestern Medicine scientists have discovered how molecular "traffic controllers" in cells influence aging and cellular ...

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 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 ...

A Northwestern Medicine study has shed light on a critical molecular mechanism underlying amyotrophic lateral sclerosis (ALS) ...

DNA is often compared to a written language. The metaphor leaps out: Like letters of the alphabet, molecules (the nucleotide bases A, T, C and G, for adenine, thymine, cytosine and guanine) are ...
