(The Guardian) – From the moment life gained a foothold on Earth its story has been written in a DNA code of four letters. With G, T, C and A – the molecules that pair up in the DNA helix – the lines between humans and all life on Earth are spelled out. Now, the first living organisms to thrive with an expanded genetic code have been made by researchers in work that paves the way for the creation and exploitation of entirely new life forms. Scientists in the US modified common E coli microbes to carry a beefed-up payload of genetic material which, they say, will ultimately allow them to program how the organisms operate and behave.
