John Paul's introduction says the big book adapts infallible church teaching to illuminate "the new situations and problems which had not yet emerged in the past." Writers of the last such catechism 426 years ago could not have imagined some sins condemned in 1992: test-tube conception, artificial insemination, speeding, drunk driving and check bouncing. There were closer medieval analogues for such evils as unjustly low wages, pornography, tax evasion and drug trafficking...
...reported last week that a hairpin-shape enzyme derived from a plant virus has shown a remarkable affinity for the virus that causes AIDS. Like the chemical scissors used in gene splicing, the hairpin enzyme hooks onto the virus' RNA and snips it into pieces. Introduced into a test-tube culture of AIDS-infected blood cells, it slowed the spread of the virus...
...parent carries the deadly and dominant gene for Huntington's chorea, for example, there is a 50% chance that any offspring will have it too. To reduce those odds to zero, doctors of the future will extract several eggs from the prospective mother and fertilize them in a test tube with her husband's sperm. When the fertilized eggs have grown to the 32- or 64-cell stage, the doctors will flick off a few cells from each and analyze their DNA. When they find an egg carrying a gene without the fatal defect, they will implant...
...couples who are concerned about passing on defective genes may be spared that agonizing dilemma, thanks to a remarkable new procedure that allows doctors to test days-old embryos for genetic abnormalities outside the womb. The technique -- which begins with in vitro, or "test-tube," fertilization and then involves plucking a single cell from an embryo the size of a grain of sand -- has already produced a healthy baby girl for a British couple with a 1 in 4 chance of having a child with cystic fibrosis, according to a report in last week's New England Journal of Medicine...

The boy is suffering from severe dehydration, and the nurse hastily inserts an intravenous tube, hooking the bottle to a branch. It is too late. As the boy's eyes roll back beneath fluttering eyelids, an older woman gently presses them shut. The boy came from the village of Malwuen, 34 miles away, where both parents and eight of his brothers and sisters succumbed...
