...laugh. But the anonymous pranksters behind these and hundreds of other hoax mailings are getting quite astute about what we will and won't fall for. And sometimes their intentions aren't merely to spread confusion or show our gullibility...
Much of what is behind the new hope is a better understanding of why the cord doesn't heal itself. In 1988 neuroscientist Martin Schwab of the University of Zurich isolated substances in the central nervous system whose sole purpose appears to be to block growth. In a healthy spine, the chemicals establish boundaries that regulate cell growth. After an injury, they do little but harm. In recent years, however, Schwab has developed antibodies that neutralize the growth blockers, allowing regeneration to occur...
Also close to reality are the so-called antiangiogenic factors, relatively nontoxic compounds that inhibit the growth of new capillaries. The idea behind this new class of drugs is that tumors cannot grow bigger than a few hundred thousand cells--about the size of a peppercorn--without growing their own blood-supply system. Researchers and patients, not to mention the owners of stock in half a dozen biotech companies, are eagerly awaiting results of clinical trials of antiangiogenic factors, which might be used in combination with chemotherapy to knock down big tumors and then prevent any surviving tumors from growing...
...assumption behind many of these futuristic scenarios is an idea that most researchers have begun to embrace but that many patients will undoubtedly find difficult to accept. That is the prediction that certain cancers may require treatment for the rest of a patient's long life. Coming out of a century that declared war on the disease, a century that felt the only reasonable response to a tumor was to annihilate it, this may be hard to imagine. But turning cancer into a controllable condition is not so different from treating high blood pressure or diabetes. "I don't think...
Once cloning loses its stigma, the urge to tinker with the genes of offspring may not be far behind. As Cambridge molecular biologist Graeme Mitchison says, "We can all be beautiful--no baldness, no wimps with glasses, no knobby knees." Olivia Judson, author of a forthcoming book called Dr. Tatiana's Sex Advice for All Creation, begs to differ: "If there is such hostility to genetically modified soya, it doesn't bode well for genetically modified people...
