Scientists Ditch Guns For Lasers To Insert DNA Into Cells

Scientists Ditch Guns For Lasers To Insert DNA Into Cells: "Step one in any project involving genetic modification is to get the genes you want into the cells you want changed. Traditionally, this meant shooting microscopic DNA-coated bullets at the cells and hoping the DNA got inside without blowing the cells to smithereens. It sounds messy, and it is. Now, researchers in South Korea have devised a super-precise method for inserting DNA into cells, and it's powered by lasers."
