...article on new software programs for students [Oct. 4]. I found it ironic that the Encarta Reference Suite 2000 was endorsed as a tool when it encourages plagiarism. An application that allows students to "cut and paste'' electronic information to index cards, then export that material to a word-processing program for editing and arranging, clearly does just that. In addition, it gives the students the impression that Encarta is the be-all and end-all in the research process. Research, however, means hunting and collecting information from a wide variety of sources to ensure that a complete and accurate...
...cerebral cortex. Snyder is now flush with confidence that neuroscience will ultimately cure many, if not all, diseases of the human brain. "By the year 2020 I hope we will have an active way of treating damaged brains. If we can further understand brain-cell regeneration and harness the process intelligently, then re-creating the brain, or at least parts of the brain, may lie within our grasp. Obviously there are lots of hurdles to overcome. But if we can capture and bottle the brain's now recognized plasticity, we can cure all sorts of things, maybe even damaged psyches...
...tumors evolve, in Darwinian fashion, as each succeeding generation of cancer cells accumulates genetic mutations. "Survival of the fittest applies to cancer cells," says Richard Schilsky, associate dean for clinical research at the University of Chicago. "We now think of cancer not as a disease but as a genetic process...
This new view has sparked innovations that will manage the process and keep it from killing large numbers of people. "We are going to see a real shift from diagnosis and treatment to prediction and prevention," declares California surgeon Susan Love, author of Dr. Susan Love's Breast Book. Indeed, if all goes well with current clinical trials, women at high risk for breast cancer will soon be able to be screened with a device that removes a sample of breast cells through the nipple. If any cells show signs of the early mutations that lead to cancer, doctors...
...long run, we have to reduce the amount of material we use in the first place. Some progress is being made--aluminum cans and plastic soda bottles have become thinner over the years, for example--but more sweeping reductions will require a whole new kind of manufacturing process...
