...West Lafayette, Ind., a Purdue University biologist who until recently was building models of viruses by laboriously fastening together hundreds of brass fittings taps away at a computer keyboard. When he is done, he has created on the screen an image of rhinovirus 14 (one of some 113 varieties responsible for the common cold) that can be turned and viewed in three dimensions. Rhinovirus 14 thus becomes the first animal virus of any kind to have its full portrait drawn...
...twelve years Biologist Phil Gruenberg has watched a foul parade float down the New River, a bile-green waterway that slices across the Mexico- California border. While scooping up water samples near the border town of Calexico, Calif., he has seen dead cats and chickens bob past, along with tires, slaughterhouse waste, laundry suds and human feces, and once, a dead man's body. The unseen horrors are, if anything, even more disturbing: the New is saturated with toxic chemicals and teems with disease-causing viruses and bacteria. Warns Imperial County Health Department Officer Dr. Lee Cottrell...
...high-tech Italian wine filter turned out to be ideal. Stainless-steel conditioning tanks were built to order. By September the partners were ready to begin ten weeks of practice | brewing. Mason says there were few surprises. At one point, a daily check of the yeast culture by Consulting Biologist Mike Sinclair showed that wild yeast had corrupted the strain, and Mason had to order another batch from Chicago. The taste of Catamount's gold and amber ales was distinct -- amber more full- bodied and slightly higher in alcohol content -- but their color was too similar, and Mason made adjustments...
...land. If the forest is allowed to grow back naturally, a closed canopy forms in about 20 years. Aided by planted seedlings, he estimates, regeneration would take only a decade. Rejuvenated dry forest attracts a wide variety of animals, which, in turn, help disperse seeds. In Santa Rosa, the biologist has counted 170 species of birds; 700 species of plants; about 13,000 species of insects, including 3,140 species of moths and butterflies; about 100 species of reptiles and amphibians and 115 species of mammals. Among the trees is the project's namesake, the guanacaste, whose branches can stretch...
...biologist hails the Costa Ricans for their support of the Guanacaste project. Since 1970, Costa Rica has been one of Latin America's most conservation-minded countries. It has set aside nearly 20% of its land for parks and reserves -- more than any other nation in the tropics. Janzen admits that he would not have attempted such a large-scale reclamation project anywhere else. But, he says, "I think this is the way of the future. Guanacaste is a demonstration of the fact that you can grow back a tropical forest if the community that lives around it comes...
