Life on Earth may have started with a molecule that still runs our cells today. As researchers probe ribonucleic acid in the lab and in ancient rocks and space dust, RNA is yielding clues that are far ...

Recent research showed that an artificially constructed self-replicating RNA system modeling primitive life at the origin 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 ...

Although there are striking differences between the cells that make up your eyes, kidneys, brain and toes, the DNA blueprint for these cells is essentially the same. Where do those differences come ...

With AI, it's now possible for researchers to predict the three-dimensional structures of proteins directly from their amino-acid sequences. But what biologists really want to predict, says Columbia ...
