An Economic Case for Banning Smoking?
An economic case for banning smoking? "The leading cause of premature death among adults in 1985 was not famine [in Africa], warfare, or the attacks of international terrorists: It was cigarette smoking,' says William Chandler, author of a report...
A Spoilage Test to Nose out the Nose
A spoilage test to nose out the nose "Flat-sour spoilage' is a particularly insidious form of food decomposition in canned goods. Caused by bacteria that thrive at high temperatures, it gains its name from the smell it imparts and the fact that it...
Blown Away: Froth of Cosmic Bubbles
Blown away: Froth of cosmic bubbles Astronomers used to think the universe was homogeneous. But recent observations of voids in the universe, of clusters of galaxies associated in ultralong superclusters, have seemed to fault the idea. Soon astronomers...
Calculating Homely Radon's Daughters
Calculating homely radon's daughters "Radon in houses is now believed to be causing more deaths than all other types of radiation exposure--natural and manmade --combined,' says University of Pittsburgh health physicist Bernard Cohen in a new report....
Fiber May Bind Colon Carcinogens
Fiber may bind colon carcinogens High-fiber diets have been associated with a reduced risk of human colon cancer. Possible explanations include: that fiber's bulk makes it less likely that carcinogens passing through the digestive tract will touch...
Herbal Medicine: Rx for Chimps?
Herbal medicine: R(x) for chimps? Dawn breaks on Tanzania's Gombe National Park, and several chimpanzees depart their tree-borne nests in search of an unusual breakfast. They pass up nearby fruit trees and take a 20-minute trek to a patch of grassland...
Mexico City's Earthquake: Lessons in the Ruins
Mexico City's Earthquake: Lessons in the Ruins Last September's disastrous earthquake should have leveled practically every building in Mexico City's downtown core, say Mexican engineers. Instead, only a relatively small number of buildings suffered...
Nicotine: A Drug of Choice?
NICOTINE: A DRUG OF CHOICE? Having resolved to make 1986 smoke-free, some people will try this month to avoid their usual smoky haunts; others will seek diversions from lighting up the next cigarette. Motivation for many will be the scientific data...
Optical Seals Record Nuclear Tampering
Optical seals record nuclear tampering The International Atomic Energy Agency (IAEA) has begun field tests of a fiber-optic seal for use at nuclear facilities and on equipment the agency inspects. This seal permits on-the-spot identification of tampering--a...
Sea-Surface Shape by Satellite
Sea-surface shape by satellite Even if there were no winds, no waves and no currents in the ocean, the sea surface would not be flat and smooth. Just as there are hills and valleys on land, so there are large bulges and depressions-- a real topography--to...

Tuning in on Radio String
Tuning in on radio string A group of theoretical physicists and astronomers proposes using radio astronomy to look for defects in the geometry and topology of the universe that are left over from a previous cosmological epoch. The defects are known...
Two New Crops in the Biotech Harvest
Two new crops in the biotech harvest Biotechnology continues to provide biologists and medical researchers with crucial materials that are too scarce in the body to be isolated for laboratory study. This month, Integrated Genetics of Framingham,...

Voyager 2: On the threshold of Uranus The Voyager 2 spacecraft's hurtling flight past Uranus, less than a week away, will be the probe's third planetary encounter since it was launched in 1977. Yet the mood of anticipation surrounding the event's...
Was a Fifth Force Felt?
Was a fifth force felt? Physicists have divided all the motions in the universe into the domains of four kinds of force: gravity, electromagnetism, the weak subatomic force and the strong subatomic force or color force. Each of these has its source...
