Laywell, UT MemphisMultipotent clones of cells derived from the adult human brain With the promises and challenges of stem cell research in the headlines, visions of artificial livers dance in the public's eye. Bioethicists, politicians, and citizens alike continue to debate whether public funds should be used to obtain cells from human embryos and fetuses. On the scientific front, however, the implications of stem cell research are even more profound than offering replacement parts.

BARKING UP THE SAME TREE Ralston Purina announced Jan. 12 an initiative to unite efforts to map the dog genome, consolidating data and planning for more. Most markers accumulated so far hail from the Baker Institute at Cornell University. The linkage map, currently consisting of about 400 markers, provides signposts along the 78 chromosomes to direct sequencing efforts. At the heart of the project are blood samples from 16 multigenerational canine families. The dog genome hardly reflects natu
