One of the most detailed genomic studies of any ecosystem to date has revealed an underground world of stunning microbial diversity, and added dozens of new branches to the tree of life.

Often described as the blueprint of life, DNA contains the instructions for making every living thing from a human to a house fly. But in recent decades, some researchers have been putting the letters of the genetic code to a different use: making tiny nanoscale computers.

Non-Standard Bonding in Base Pairs

A new study provides insight into base pair bonding in artificial DNA polymerase. Researchers focused on a previously unknown base pair: iso-guanine and methyl-pyrimidinone.

Earth's Viral Diversity

The number of microbes in, on, and around the planet - on the order of a nonillion, or 10^30 - is estimated to outnumber the stars in the Milky Way.

Recreating A Primordial RNA World

Scientists at The Scripps Research Institute (TSRI) have taken a big step toward the laboratory re-creation of the "RNA world," which is generally believed to have preceded modern life forms based on DNA and proteins.

The relatively recent development of high-throughput sequencing (HTS) techniques has revealed a wealth of novel sequences found in very low abundance: the rare biosphere.

Multicellularity--the integration of previously autonomous cells into a new, more complex organism--is one of the major transitions in evolution.

A new study could explain why DNA and not RNA, its older chemical cousin, is the main repository of genetic information.

Early life forms on Earth are likely to have mutated and evolved at much higher rates than they do today, suggests a new analysis from researchers at the University of North Carolina.

Viruses that infect bacteria are among the most abundant life forms on Earth. Indeed, our oceans, soils and potentially even our bodies would be overrun with bacteria were it not for bacteria-eating viruses, called bacteriophages, that keep the microbial balance of ecological niches in check.
