Sexton added that the most controversial topic taken up at the conference was the relationship between gas cooking and respiratory health. Some studies have linked the presence of gas stoves in homes and reduced lung function in children. Nitrogen dioxide, one of the by-products of gas combustion, has long been thought the causative agent...
...John D. Spengler, in a paper presented at the symposium, found no correlation between measured nitrogen dioxide levels and lung function. "This is not conclusive, as it was based on a small sample size," Sexton said, adding also that it did not preclude the possibility that short-term, "peak exposures" to the gas might be harmful...
...Angeles, Calif., was one of several firms spawned by the 1960s vogue for freezing human bodies until the cures for various diseases were found, at which time the bodies would be thawed and presumably revived. When Cryonics Interment went broke after five years, however, the supply of freezing liquid nitrogen was cut off and the eight or so bodies in the company's burial capsules thawed and decomposed. The relatives of three of the deceased-who had paid a total of $31,294 to have their loved ones preserved-sued Cryonics Executive Robert Nelson and Mortician Joseph Klockgether. Nelson...
...reason for the mishap may not be known until NASA and Rockwell officials complete their separate investigations. Yet some of the circumstances are already known. Apparently, safety supervisors erred in clearing the technicians to go into the craft. Before a launch rehearsal, it is standard procedure to use nonflammable nitrogen to flush oxygen-laden air out of the engine compartment, where even the slightest friction or electrical spark can touch off a deadly fire. Afterward, the technicians, all of whom had considerable experience working with the shuttle, went into the nitrogen-saturated compartment without their air packs, the portable breathing...
...Agriculture, Genentech is already working on a vaccine against hoof-and-mouth disease, which kills off millions of food-producing animals a year round the world. Geneticists also hope to endow such basic food plants as wheat, corn and rice with the ability to "fix'' or draw their own nitrogen from the air. At present, nitrogen must be provided in expensive fertilizers made from increasingly costly petroleum products. But scientists using plasmids have already cloned some of the nitrogen-fixing genes found in bacteria. And in an experiment at Cornell, a complete set of 17 such genes was transferred from...
