...matter much. Corporate giants like DuPont already put synthetic biology to industrial use. In the company's Loudon, Tenn., plant, for example, billions of E. coli bacteria stew inside massive tanks. The bacteria's genomes contain 23 alterations that instruct it to digest sugar from corn and produce propane diol, a polyester used in carpets, clothing and plastics. The hard-working bugs churn out 100 million lbs. (45 million kg) of the stuff each day, and all it took was a little tinkering with their genomes, not the construction of a new one. "In terms of whether I can think...

...glory that was Greece and the grandeur that was Rome have been pretty well picked over on dry land. But under the surface of the Mediterranean, says Archeologist Philippe Diolé, lie untold sunken deposits of classical history and art. In a new book, 4,000 Years Under the Sea (Messner; $4.50), Diolé tells how diving archeologists are just beginning to exploit the submarine digging grounds...
Syrupy Wine. Such sites are safe from most archeologists, who are generally more learned than athletic, but Philippe Diolé, director of Undersea Archeological Research for the French National Museums, is not merely learned. He is a "skin-diver," and loves nothing better than swimming under water with mask and air cylinder. Often the bottom of the sea is a desert with nothing to show that man has ever sailed over it, but sometimes an encrusted object looks somehow suspicious to Diolé's well-educated eye. Diolé investigates. He finds a chunk of Carrara marble...
Treasures in Wait. Diolé believes that "the future of archeology lies in the sea." Certainly many wrecks, some of them stuffed with well-preserved art objects, await the diving diggers. Those that lie near the shore in clear water are apt to be damaged by wave action and madre growths. Those that lie deeper or near the mouths of rivers which cover them with silt are better preserved, but are also harder to find and explore. Archeologists, Diolé thinks, should be taught to dive...
