Researchers will gather in London this week to outline plans to promote one of the most audacious, and controversial, scientific ideas of the 21st century – synthetic biology.

The new discipline, established by scientists such as human genome pioneer Craig Venter, involves stripping microbes down to their basic genetic constituents so they can be reassembled and manipulated to create new life forms. These organisms can then be exploited to manufacture drugs and fuels or to act as bio-sensors inside the body.

However, some researchers warn that synthetic biology – which is accelerating at a dramatic pace – also poses dangers. In particular, they fear it may already be possible to create deadly pathogens, such as polio or smallpox viruses, from pieces of synthetic DNA ordered over the internet. In future, completely new – and highly dangerous – microbes could be made this way. Continue reading »
