Researchers at the University of York have shown that molecules brought to earth in meteorite strikes could potentially be converted into the building blocks of DNA.

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.

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

A new study shown that meteorite impacts on ancient oceans may have created nucleobases and amino acids.

Ideas about directing evolution of life forms on Earth and finding life on other planets are rapidly morphing from science-fiction fantasy into mainstream science, says David Lynn, a chemist at Emory University.

Scientists at The Scripps Research Institute have engineered a bacterium whose genetic material includes an added pair of DNA "letters," or bases, not found in nature. The cells of this unique bacterium can replicate the unnatural DNA bases more or less normally, for as long as the molecular building blocks are supplied.

Weakly Interacting Massive Particles (WIMPs) may constitute a large fraction of the matter in the Universe.

If you have been watching the new series "Cosmos" recently then you have see Tardigrades or "water bears" featured. These creatures are remarkably resistant to a wide range of conditions that humans would consider extreme - if not deadly.

All living organisms on Earth could soon have a new name if a Virginia Tech professor has his way. Boris Vinatzer has developed a system that classifies and names organisms based on their genome sequence.

Modeling a Near-optimal Genetic Code

Researchers have created a model that may explain the complexities of the origins of life. Their work, which appears in the Journal of the Royal Society Interface, offers new insights into how RNA signaling likely developed into the modern "genetic code."
