...cluster of high- profile cases turns Manhattan courtrooms into SRO theaters. The line forms early to see former beauty queen Bess Myerson or accused child murderer Joel Steinberg...
...series of deaths in the booming suburbs of Cobb County, just north of Atlanta, are part of a "suicide cluster," an affliction that has inexplicably visited half a dozen U.S. communities in this decade. The Centers for Disease Control began a detailed study of the county last summer after the suicide rate there was found to be 33% higher than the national average. The county (pop. 400,000) has already suffered 51 suicides this year, including six teen deaths, and expects to hit a record 70 suicides by December. Authorities speculate that the root cause may be explosive growth. "Fifteen...
...biochemistry, function often follows form. Using sophisticated X-ray techniques to analyze the atomic structure of life's most basic components, scientists have been able to unlock astonishing mysteries. Focusing on a bacterium that uses a simple method of photosynthesis, Michel concentrated on a cluster of proteins that spans the organism's outer membrane, called the photosynthetic reaction center. These so-called membrane-bound proteins are like plants themselves: antennae protrude from cell surfaces, anchors hold them in the membrane, and rootlike tentacles reach into the cell's interior. But the molecules resisted study...
...however, Michel was able to isolate the protein cluster from the membrane and concentrate it into its crystalline form. For the next three years, at Huber's direction, the researchers used X-ray crystallography to determine the structure of the protein cluster's 10,000 atoms. The laborious research opens the possibility that someday scientists will be able to produce solar cells that mimic the design of photosynthesizing molecules...
