Studies in humans and large animals indicate a relationship between the uterine microbiome composition and endometrial receptivity. Despite many studies have been performed, the analysis of the ...

While evolution is often considered from a DNA- and protein-centric view, RNA-based regulation can also impact gene expression and protein sequences. Here we examine interspecies differences in ...

"DNA guides are far cheaper and easier to manufacture than RNA guides, and they are far more stable," Jain said. "While RNA molecules degrade quickly, DNA can remain intact for long periods." Together ...

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 ...

Long known as a messenger within cells, RNA is increasingly seen as life’s molecular communication system — even between organisms widely separated by evolution. For a molecule of RNA, the world is a ...
