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.

LIFE SCIENCES BY BERNARD DIXON European Editorial Offices The Scientist Uxbrldge, U.K. " Positron emission tomography studies in 20 Swedish army officer cadets have revealed metabolic changes in the same regions of the brain during both tactile learning and tactile recognition. This exciting glimpse of brain metabolism accompanying conscious activity appears in a new journal launched by the European Neurosciences Association and designed to interest the entire universe of neuroscientists, fro
Bioscience Make-Over

Echoing the centuries-old debate among scientists over how to organize and name Earth's species, authors of National Research Council (NRC) reports rating research-doctorate programs have also struggled over the "taxonomy" of disciplines within the biosciences. Allan Cartter, in his 1966 report An Assessment of Quality In Graduate Education (Washington, D.C., American Council on Education), observed that grouping programs within the biological sciences represented a challenge, owing to the vari
Stem Cell Discoveries Stir Debate
Douglas Steinberg | Nov 12, 2000 | 9 min read
Editor's Note: This is the first of two articles on questions raised by recent stem cell discoveries. The second article, focusing on various organs and the nervous system, will appear in the Nov. 27 issue of The Scientist. Researchers first isolated embryonic stem cells (ESCs) from mouse blastocysts almost 20 years ago, and a paper announcing the discovery of human ESCs emerged in 1998. Adult-derived stem cells (ASCs) have since become the rage in certain quarters of biology, with unexpected--
