...procedure, reported last week at a meeting of the American Society of Human Genetics in Baltimore, is based on analysis of the "first polar body," a small packet of chromosomes sloughed off from the human egg during cell division. First the researchers remove several eggs from a woman's ovaries. Next the first polar body is detached, and a new genetic test called ! polymerase chain reaction is employed to analyze the chromosomes, which are complementary to those left in the egg's nucleus. Eggs that are not defective can then be selected and used in an increasingly common procedure known...
...billionths of a meter (nanometers). In Engines of Creation, the nanotechnologist's bible, K. Eric Drexler envisions a world in which everything from locomotives to cheeseburgers is assembled from molecular raw materials, much as proteins are created from their amino-acid building blocks by the machinery of a living cell...
...good metaphor for The Night Thoreau Spent In Jail is the scenery used: sparse and effective, but a little empty. The play takes place on a stage bare except for the two beds in the prison cell, which sometimes turn into benches, and a chair or two, which are sometimes used as a boat. And these are sufficient...

...experiments begun in the mid-'70s at the University of California at San Francisco, Bishop and Varmus resolved a spirited debate over oncogenes -- the genes, or units of heredity, that cause cancer. Researchers had previously theorized that cancer genes were separate entities, unrelated to the healthy functioning of a cell. But in studies of a cancer-causing virus in chickens, Bishop and Varmus found that oncogenes were normal genes, vital to cell growth and development, that had somehow gone awry -- probably as a result of mutations induced by carcinogens such as cigarette smoke and radiation. The team thus helped explain...
