Fish, on the other hand, survive in very cold water. Scientists identified a particular gene which enables a flounder to resist cold and used the technology of genetic engineering to insert this 'anti-freeze' gene into a tomato. This makes it possible to extend the growing season of the tomato. The marketing of genetic engineering inspires visions of perfect health, long life, and miracle foods. The reality is that these claims are often completely unsubstantiated and sometimes simply wrong. ....
