A Radical Pope's Challenge to the American Catholic Church
The transformation of a church from a champion of social justice to one focused on divisive issues is examined, highlighting the potential for renewal in the "age of Francis." As the first non-European pope in over a thousand years, Pope Francis is revitalizing a church burdened by scandal and negative publicity, offering new opportunities for change and a redefined mission.
The relationship of cell lineage and differentiation is one of the most intriguing problems in developmental biology. In most higher organisms, the analysis of the cell lineage has to rely on indirect methods. Only in the most suitable systems, like the nematodes, can the pattern of cell division be determined by direct observation under the microscope. In cases where this is not possible, the fate of the cells has to be examined by using cell markers. Most suitable for this purpose are genetic markers, provided that they do not interfere with the developmental pathway to be studied. However, suitable genetic markers and techniques for generating genetic mosaics are available in a few organisms only. Therefore, this volume is largely concerned with Drosophila and the mouse, which have been studied most extensively. In 1929 STURTEVANT introduced the analysis of gynandromorphs into devel opmental genetics. However, this important contribution remained largely unnoticed until the late sixties, when the potential of this technique for deter mining embryonic fate maps and the number of primordial cells was exploited, and the methodology extended to the mapping of mutational foci. Mitotic recombination was demostrated by
This book explores how a church once known as a force for social justice became known for a few key wedge issues, then looks at the opportunities for change in the age of Francis. The first non-European pope in more than a millennium, Pope Francis is shaking up a church that has been mired in scandal and demoralized by devastating headlines.
