A technique called CRISPR (clustered regularly interspaced short palindromic repeats) snips a plant's own DNA as needed -- rather than inserting bits of foreign DNA as in past gene-splicing
. The revised genome duplicates itself endlessly as new generations of improved crops ensue.
Scientists will use a gene-splicing
therapy to try to cure beta thalassaemia, a serious blood disorder that cuts output of haemoglobin, which carries oxygen to cells.

Feb 20-Mar 20 PISCES YOU'VE never really thought of yourself as a dog person, but all the gene-splicing
and painful surgery will prove you were wrong.
Superhero movies tell us that gene-splicing
is as easy as getting bit by a spider, or that finding criminals is a breeze with the help of DNA evidence (always conveniently found, always instantly analyzed).
That led to guidelines and federal regulations of recombinant DNA, the gene-splicing
technology that underlay the founding of Genentech and other biotech companies and revolutionised the production of many pharmaceuticals.
is just a more efficient and neater way of achieving the same goals.
Back in 1974, several prominent biologists concerned about the "potential bio-hazards" posed by then-new gene-splicing
techniques that had been described in leading scientific journals called for a time-out on certain kinds of experiments.
A 20-year scientific consensus holds that gene-splicing
is an extension, or refinement, of less precise and less predictable techniques for genetically improved products with which consumers and government regulators have long familiarity and comfort.
But after repeated use of atrazine, resistant weeds began to appear just a decade after it was first introduced in 1958, long before the techniques of gene-splicing
were even invented.
technology to create genetically modified organisms (GMO) already exists in food supplies: 91% of soy and 73% of corn grown in the U.S.
