Scientists use a 'gene gun' to insert a gene from a flowering plant called rockcress into the cells of wheat seeds. The genetically modified wheat became more resistant to a fungus called take-all, which in real life can cause "a 40-60% reduction in wheat yields." T-cells from six HIV+ patients were removed from their bodies, treated with a zinc-finger nuclease designed to snip a gene out of the cell's DNA, and put back in the patients.  Removal of the gene mimics a naturally occurring mutation which confers resistance to the HIV virus.  But only 25% of the treated cells showed evidence of…
