...terms it seems strangely inefficient to have all those eggs sitting around for decades, slowly going bad. Men, by contrast, churn out new sperm all the time. Insects make new eggs too, well into maturity. "Fruit flies know fresh eggs are better than stale," says Jonathan Tilly, a reproductive biologist at Harvard Medical School and Massachusetts General Hospital. "So why shouldn't mammals...
...Harvard and Cambridge-educated molecular biologist, I was disheartened by the Crimson’s recent uninformed attack on PETA’s campaign to convince health charities to stop funding experiments on animals (Staff Ed, “PETA’s Pedigree”, March...
...that Schiller and his wife are ready to retire, Gross, a biologist doing post-doctoral work at Boston University, and her older brother Alexander Schiller, a lawyer, both decided not to continue the business...
...destroy just about anything that crosses their path - particularly DNA. A glancing blow that damages but doesn't destroy a cell could lead to a genetic mutation that allows it to keep on growing and dividing. The abnormal growth is still not a tumor, says Lisa Coussens, a cancer biologist at the Comprehensive Cancer Center at the University of California, San Francisco. But to the immune system, it looks very much like a wound that needs to be fixed. "When immune cells get called in, they bring growth factors and a whole slew of proteins that call other inflammatory cells...
...doesn't forbid human cloning. Responsible scientists wouldn't try it, but an unethical researcher could read the Science paper and attempt to use the technique to bring a clone to term. "I'm afraid that some nitwit is going to try," says Larry Goldstein, a cellular and molecular biologist at the University of California at San Diego. But given the high rate of spontaneous abortions and genetic defects seen in other species, it's not likely to work. The Science paper is a recipe for cloning, said Kennedy, "only in the sense that 'catch a turtle' is the recipe...
