Like life, the series begins slowly. Attenborough ventures back to the planet's earliest days, some 3 billion or so years ago. DNA molecules lead to bacteria, which in turn are transformed into protozoans. Over hundreds of millions of years, the oceans begin to swarm with increasingly complicated forms of life. The records from those days are scanty at best, and, to the layman, one fossil looks much like another. There may be books in running brooks and sermons in stones, but they do not translate very well into...
Severe immunological vulnerability poses some tricky medical problems. "Specific infections can be treated," says Internist Henry Masur of New York Hospital-Cornell Medical Center, "but the person will usually just come down with another infection two months later." Masur has seen homosexual patients be sieged by bacteria, fungi and offbeat viruses, all in quick succession. "Why this group has something suddenly wrong with its immunity is a mystery...
...three in the arsenal against cancer are surgery, radiation and drugs. But a new therapy, which has produced "exciting" preliminary observations, makes use of an unexpected weapon: bacteria. Staph germs (Staphylococcus aureus) are in fact essential in a blood-washing treatment under study at Baylor College of Medicine in Houston. In the technique, developed by Immunologist David Terman and his colleagues, blood plasma is removed from a patient and run through a device containing beads of charcoal coated with protein A, a component of the staph bacteria. The plasma is then returned to the patient. The scientists speculate that...
Alfred F. Ferullo, director of environmental quality at the MDC said sewage treatment plants have made great improvements in the water quality, but high bacteria counts caused by storm water runoff and general urban pollutants will probably keep the water below federal swimming standards. The MDC has concentrated its cleanup efforts against the major cause of pollution--sewage overflow from Boston's antiquated sewer system, he added...
However, restriction of stormwater dumping by Boston and Cambridge--a major cause of bacteria growth--has not even been considered, Ferullo said. He added that current treatment plants, which provide only rudimentary waste processing, cannot yet handle all the overflow...
