UPDATE: Scientists develop first examples of RNA that replicates itself indefinitely
Thanks to Eric for the link.
A new molecule that performs the essential function of life – self-replication – could shed light on the origin of all living things.
If that wasn't enough, the laboratory-born ribonucleic acid (RNA) strand evolves in a test tube to double itself ever more swiftly.
"Obviously what we're trying to do is make a biology," says Gerald Joyce, a biochemist at the Scripps Research Institute in La Jolla, California. He hopes to imbue his team's molecule with all the fundamental properties of life: self-replication, evolution, and function.

One day in May of 2011, Shaun Winterton was looking at pictures of bugs on the Internet when something unusual caught his eye. It was a close shot of a green lacewing — an insect he knew well — but on its wing was an unfamiliar network of black lines and a few flecks of blue.
