Adam Rutherford meets a new creature created by American scientists,
the spider-goat. It is part goat, part spider, and its milk can be used to
create artificial spider’s web.
It is part of a new field of research, synthetic biology, with a radical aim:
to break down nature into spare parts so that we can rebuild it however
we please. This technology is already being used to make bio-diesel to
power cars. Other researchers are looking at how we might, one day,
control human emotions by sending ‘biological machines’ into our brains.
