...into plants and animals through simple crossbreeding, but for the most part scientists merely reshuffled genes within a particular species. Corn could not be crossed with soybeans, nor cows with pigs. Now plants as diverse as tomatoes and cotton have been equipped with genes that scientists have borrowed from bacteria. Shrimp may soon be given disease-fighting genes taken from sea urchins. Eventually, crops and farm animals may be raised to produce not just food and clothing but also a wide array of chemical compounds and human proteins like insulin. While research on plants has taken the lead, work with...
...That may be tricky, given the concerns raised by some environmental and animal-rights groups. Protests have already greeted the likely approval by the U.S. Food and Drug Administration of biotechnology's first major agricultural product, a natural hormone called BST, which can be mass-produced in genetically altered bacteria. BST injections make cows produce more milk, but farmers worry about a possible oversupply of dairy products that could drive down prices. Moreover, some opponents question the safety of milk from cows with extra...
...environment alike. Similarly, the discovery that plants can be "vaccinated" against disease by equipping them with viral genes ought to reduce reliance on chemical insecticides. Currently, farmers battle such diseases by spraying the insects that carry them. Genetic engineering could also be used to give livestock more resistance to bacteria, reducing the need to feed antibiotics to farm animals...

Cusack said Cambridge has recently modernized its water system to cut the level of THMs, which form when chlorine added to water to kill dangerous bacteria reacts with organic material, such as leaves and wood. Recent changes to the system include adjustments in the filtering process and a switch to non-chlorine based chemicals, Cusack said...
