Comparing the human genome with those of other organisms, from bacteria to insects to mammals, will help biologists understand how more complex species evolved from simpler ones--and even pinpoint the precise bits of genetic information that are uniquely human. "It has to be a milestone in human history when you have a first look at your instruction book," says James Watson, who with Francis Crick discovered the structure of DNA a half-century ago. "Having this book will change the world...
Antibodies are also being drafted to prod the immune system itself into attacking cancer cells. Clinicians have long dreamed of marshalling the body’s own defenses against cancer, if only they could get the immune system to recognize cancer cells as easily as it spots foreign invaders like bacteria and viruses. Researchers at Dendreon Corporation, in Seattle, Wash., have found a way to do just that by enlisting dendritic cells, some of the body’s most potent immune stimulators...
Accidents happen: aniline dye falls into a 19th century German researcher's petri dish that contains a bacterial culture, revealing that it preferentially stains and kills certain bacteria. The discovery eventually makes chemotherapy possible...
...only to discover a carton of penicillin, Microsphere is the nontoxic microbial biocide for you. Packaged in perishables and clothing containers as a fine powder, Microsphere is inactive until humidity hits. Then, like a chemistry teacher's long-aborning dream, it turns into a gas that safely fights off bacteria and mold...
Ruvkun and other scientists choose to work with the laboratory roundworm, a tiny bacteria-eating soil-dweller, because the sequence of its entire genome is known and its 302-neuron nervous system has been described in detail...
