...complete, the gene chip is ready for use. You take a sample of blood from a patient who has just developed a raging HIV infection. Various genes in his immune system are churning out millions of RNA molecules that will assemble the proteins needed to combat the infection. You extract the RNA and break it into pieces, tag each piece with a fluorescent chemical and pour the whole mess over the gene chip. The RNA tightly binds only to its exact DNA complement on the chip. The fluorescent tag tells you where on the chip you have a match. Then...

For example, most studies of ginkgo biloba, which appears to delay the progression of early Alzheimer's disease in some patients, have been conducted on an extract produced by Schwabe of Germany and distributed in the U.S. by Nature's Way (Ginkgold) and Warner-Lambert (the Quanterra line). The best-studied version of St. John's wort, which seems to work for mild to moderate depression, is Kira, produced by Lichtwer...
