Just 45 years ago, the age of gene modification was born. Researchers
could create glow-in-the-dark mice, farmyard animals producing drugs in
their milk, and vitamin-enhanced rice that could prevent half a million
people going blind every year.
But now GM is rapidly being supplanted by a new system called CRISPR or
'gene editing'. Using this approach, scientists can manipulate the genes
of almost any organism with a degree of precision, ease and speed that
we could only dream of ten years ago.
But is it ethical to change the genetic material of organisms in a way
that might be passed on to future generations? If a person is suffering
from a lethal genetic disease, is it even more unethical to deny them
this option? Who controls the application of this technology, when it
makes 'biohacking' - perhaps of one's own genome - a real possibility?
Nessa Carey's book is a thrilling and timely snapshot of a technology
that will radically alter our futures.
