...find the statement that "a clear-cut leaves a sharp demarcation line between a woodland full of life and a biological ruin" complete nonsense. As a hunter, I know that the place in a forest to find the largest concentration of all manner of critters is in the regrowth that occurs in burns and clear-cuts. Inasmuch as we seldom let fire do its work in the forest, we are probably doing diversity a favor by selective logging and clear-cutting! DALE ROSS Ashland...
...reporter Joan Dunning, accelerated logging has devastated the land and the streams that flow through it. From the Redwood Forest (Chelsea Green; $24.95) relates a brutal progression. Pacific Lumber, under Maxxam and Hurwitz, started widespread clear-cutting, a practice that leaves no tree standing and works against natural regrowth. Then Pacific Lumber began cutting through the winter months, and on dangerously steep slopes, giving the impacted ground and the silted streams no respite...
Until the mid-1980s, researchers assumed that nerves in the central system were simply incapable of regrowth once they were damaged. A researcher at McGill University in Montreal, Alberto Aguayo, turned this assumption around by demonstrating that a nerve taken from an animal's leg and grafted onto the central nervous system allowed the nerve cells to grow along the transplanted nerve. Evidently there was nothing wrong with spinal-cord nerves, but something in the central nervous system was impeding their growth...
...regrowth of Judaism is not unprecedented. The Jews of Persia survived the violence under the regime of Ahasuerus, the Jews of Europe outlasted the Inquisition, and pogroms failed to wipe out the Jews of the Russian Empire. Yet cruel as generations of persecutions were, all stopped short of the Nazi attempt at genocide. There were 8.3 million Jews in Eastern and Central Europe before the rise of Hitler. Some 450,000 fled the Nazis before World War II. More than 5 million died in the Holocaust. After the war a few hundred thousand of the survivors left immediately for Israel...
...gene that normally limits cell growth. Up to half of patients who undergo balloon angioplasty to relieve arterial blockages suffer renewed arterial narrowing within six months. Researchers may have ! identified the cause: the cytomegalovirus, which appears to limit the protective benefits of the p53 gene, thus leading to the regrowth of muscle cells in vessels treated with angioplasty...
