...enjoyed many measurements and many results. Despite the common myths about science, it was not lonely work. Much of the pleasure came from companionship. Most of our experiments lacked discernable practical goals. We followed our hunches, working with cancer viruses from chickens and mice, supported largely by grants from the NIH. Eventually, over many years, patterns emerged. We had learned that cancer genes in viruses are derived from normal cellular genes--some of the genes that guide our growth and development. These genes, now called oncogenes, undergo the mutations that are the defining events in cancer. Obscure viruses from experimental...
...Nature Medicine, the researchers report that they have frozen spermatogonial stem cells--the cells that make sperm--thawed them and coaxed them back to life. And in a companion paper in the journal Nature, the same scientists say they have taken stem cells from rats and implanted them in mice, which have then produced fully functional rat sperm...
...VITAMIN E and stay perky? Studies on mice suggest that the nutrient, which is already thought to ward off cancer and heart disease, may also slow aging of the brain and the immune system...
...these pills safe? Not everyone agrees. Twenty-two neurologists petitioned the FDA last winter to delay approval of dexfenfluramine, citing studies that show it causes brain damage in laboratory animals ranging from mice to baboons. Critics are also concerned about an increased risk of pulmonary hypertension, a condition that can lead to heart failure. The FDA, however, judged the threats minimal. Proponents point out that dexfenfluramine has been used abroad by millions of people over the past decade with no major problems...
