...this round of additions, the Deer Island facility was upgraded to secondarily treat all wastewater--thus fulfilling one of the Clean Water Act's original mandates--to remove 85 percent of carbonaceous oxygen-depleting matter, bacteria and suspended solids before re-releasing the treated water through outfall pipes into Boston Harbor...
...moment, the scientists report, the robotyke has the brainpower of bacteria: "We hope to get up to insect level in a couple of years." Meantime, in another part of the forest, the human genome project is nearly complete. Peering into the future, one dimly discerns a convergence. Here are the projected patterns...
Arkin is developing a similar program he calls bio/SPICE that he hopes will do for the cell what SPICE did for the chip. His first targets are simple bacteria. "They're still complicated enough that we get depressed," Arkin admits with a laugh. But he has already had some success grouping reactions together by the kinds of jobs they do. And, sure enough, some of them bear a remarkable resemblance to the gates and switches of an electronic circuit...
...continuing flap over Bt corn and cotton--now grown not only in the U.S. but also in Argentina and China--has provided more fodder for debate. Bt stands for a common soil bacteria, Bacillus thuringiensis, different strains of which produce toxins that target specific insects. By transferring to corn and cotton the bacterial gene responsible for making this toxin, Monsanto and other companies have produced crops that are resistant to the European corn borer and the cotton bollworm. An immediate concern, raised by a number of ecologists, is whether or not widespread planting of these crops will spur the development...
SPECIAL DELIVERY Up to 40% of pregnant women harbor a nasty type of strep, which if transmitted to a newborn during childbirth can cause pneumonia, blood poisoning and even meningitis. Screening for the bacteria used to take days. Now doctors have come up with a speedier test, called a rapid PCR. It can determine on the day of delivery--in less than an hour--whether strep is present. If so, the bug can be wiped out with intravenous antibiotics a few hours before the baby is born...
