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...
Skeptics warn against too much giddy hope that damaged spines will become whole anytime soon. Treatments may be many years off, they caution, and only incrementally helpful--restoring wrist motion to a person who has none, for example. Most researchers, though, are more optimistic. Over the course of 10 years, they say, the riddles of the cord have been solved. The question now is not what the treatments for an injured spine should be, but how best to implement them. At hospitals such as the Karolinska Institute in Sweden and the University of Florida, human trials are already getting under...
...will be given tools for detecting the earliest stages of many cancers--in some cases when they are only a few cells strong--and suppressing them before they have a chance to progress to malignancy. Beyond that, nobody can make predictions with any accuracy, but there is reason to hope that within the next 25 years new drugs will be able to ameliorate most if not all cancers and maybe even cure some of them. "We are in the midst of a complete and profound change in our development of cancer treatments," says Richard Klausner, director of the National Cancer...
First, the good news: people will still be trying to get each other into bed in 2025, though one can only hope the pickup lines will be different by then. Now here's the revolutionary (or should I say evolutionary) news: sex will seem a lot less necessary than it does today. Having sex is too much fun for us to stop, but religious convictions aside, it will be more for recreation than procreation. Many human beings, especially those who are rich, vain and ambitious, will be using test tubes--not just to get around infertility and the lack...
...vaccine is our only real hope to avert a disaster unparalleled in medical history. A concerted research effort was launched three years ago in the U.S., and hints of promising strategies are emerging from experiments in monkeys. But even if an AIDS vaccine is developed before 2025, it will require an extraordinary effort of political will among our leaders to get it to the people who need it most...
