Soon after the first tremor, seismologists began trying to map out the newly revealed fault and determine how it is connected to other fissures in the region. To do this, the scientists will have to track the locations of hundreds of aftershocks, a lengthy and tedious process. At first it was thought that the quake might have resulted from a previously unmapped extension of the Oak Ridge Fault, which angles past the city of Ventura and into the Pacific Ocean. But as researchers fanned out through the San Fernando Valley, other theories emerged, including the possibility that the fault...
...city of Manassas is not happy with the kind of attention it has been receiving, and so has prepared this map to set the record straight. (Excerpts from the accompanying text are at right...
...matter what path the genetic revolution takes, the first step is to find the genes: the discrete segments of DNA that are the basic units of heredity. For scientists racing to map the human genome (as the complete set of genes is called), the past year has been extraordinarily productive. With automated cloning equipment and rough computerized maps to steer them through the vast stretches of DNA, scientists are finding human genes at the rate of more than one a day. In the past 12 months they have located the genes for Huntington's disease, Lou Gehrig's disease...
...from scratch, says Collins, is like "trying to find a burned-out light bulb in a house located somewhere between the East and West coasts without knowing the state, much less the town or street the house is on." Even the most comprehensive DNA chart available -- the human-genome map completed late last year by Daniel Cohen and colleagues at the Center for the Study of Human Polymorphism in Paris -- is terribly sketchy and riddled with errors...
