...spray being used is not expected to hurt people, mammals or birds. It consists of naturally occurring bacteria that are lethal only to caterpillars. Some environmental groups and residents have opposed the program because the spray will eliminate butterflies and other insects as well. But officials of the state agriculture departments believe the indigenous species will quickly regenerate...
...scientists at the University of Genoa, Italy, noted that the rays coming from unshielded quartz-halogen lamps can induce mutations in the DNA of bacteria. Since genetic mutations are one cause of cancer, they decided to move up a few rungs on the evolutionary ladder. They subjected specially bred hairless mice to the lights 12 hours a day for a year and found that every one developed skin tumors -- most benign, but some cancerous. The research, reported in the British journal Nature, involved only a handful of mice, so it was labeled a pilot study. But the results were...
Cows are contributing to global warming. To a measurable extent, they are. The symbiotic bacteria that dwell in every cow's gut enable grazers to break down the cellulose in grass. As a by-product, these bacteria produce considerable amounts of methane, which, like carbon dioxide, is a heat-trapping greenhouse gas. The methane periodically gusts forth from grazing herds in the form of rumbling postprandial belches. But if cattle contribute to the global methane load, they are hardly alone. Swamps, termite mounds and rice paddies are all hosts to similar sorts of bacterial methane factories...
...unbelievable -- from demons causing susceptible serial killers to act up to researchers who find top-secret code words in George Bush's speeches when they are played backward, leading them to the conclusion that the President and others thereby unconsciously reveal this information. Thousands of Americans think bacteria do not cause disease, and are convinced that death is an aberration; they are known as Christian Scientists...
...reactions that protect cells and convert food into energy and living tissue. Some vitamins are produced within the body. Vitamin D, for example, is manufactured in the skin during exposure to sunlight, and three other vitamins (K, biotin and pantothenic acid) are made inside the human gut by resident bacteria. But most vitamins must be ingested...
