...promote two activities: the development of technologies designed to reduce production of carbon dioxide and other greenhouse gases, and the sharing of those methods with developing countries. miti is financing an ambitious effort to generate clean-burning hydrogen, which would not contribute to global warming, by using genetically engineered bacteria. There are also tax breaks and low-interest loans available for environmentally sound industrial projects, and local governments can get tax relief when they purchase electric- rather than gasoline-powered vehicles...
...result of a flood that occurred between 100 B.C. and A.D. 100. The scientists' studies also showed that the presence of 17 people inside the tomb for a mere half an hour could raise the relative humidity from 30% to 50%, more than high enough to allow bacteria to grow...
...treat," he told us. "Every animal out there makes some, and Nature takes care of it." Modeled on a wetlands, his plant is a series of tanks open to sunlight. The sewage flows through so slowly you can't see it move. At the front end, there are only bacteria. Farther down you can find worms, shrimp, and then fish. "When we wanted to start the plant running, we needed all the little beasties you find in nature, so we went to a few ditches around Providence and collected a bucket of slop, then poured that mess into our tank...
...their study, which was reported in the research journal Science, Michigan's Yves Poirier and his colleagues capitalized on the environmental know-how of a select group of bacteria. In much the same way that humans store excess nutrients as fat, these germs turn sugar into the plastic molecule polyhydroxybutyrate, or PHB. They can also digest the polymer, which means it is biodegradable...
...researchers transplanted the gene for PHB from the bacteria into relatives of the mustard plant. Using energy from the sun and carbon dioxide from the air, the plants manufactured significant amounts of phb. Unfortunately, the process also stunted their growth. But eventually, Poirier expects, scientists will learn how to regulate the hybridization procedure well enough to keep these plastic producers healthy, and perhaps one day alleviate guilt over discarded bottles and wrappers...
