...headlines could cure deadly diseases, then everyone would have rejoiced last week. Across the U.S., newspapers heralded the development by scientists from Bristol-Myers Squibb of a "smart bomb," or "magic bullet," against cancer. The weapon, a type of protein called a monoclonal antibody combined with an anticancer drug, has wiped out a wide variety of tumors in laboratory mice...
British scientists have managed to deactivate cancer cells in mice. They moved a gene from a bacterium into the tumor cells; once inside, the gene forced the cells to produce a toxic protein that then shut off the tumor cells' ability to reproduce and spread...
...several years, researchers have known that the brain cells of Alzheimer's victims are clogged with an overabundance of beta amyloid. The sticky protein forms plaques that can kill the cells, gradually producing memory loss. But why do some people have an excess of the amyloid, and why does it accumulate in the brain...
Roses proposes that amyloid has an accomplice: a blood protein called ApoE. Its main function seems to be transporting cholesterol, but according to Roses, ApoE can also latch on to amyloid and cart it into brain cells. How often that happens may depend on what type of ApoE a person has, which in turn depends on the genes that direct the making of ApoE. Those genes come in at least three varieties -- dubbed E2, E3 and E4 -- and everyone has two of the genes, one from each parent...
...today only a small percentage of the people regularly eat the $55-a-pound delicacy. The industry has been trying to muster public opinion by distributing slick brochures. One titled "Let's Take a New Look at Healthy Whale Meat" contends that it is high in protein, low in fat and "good for food-allergenic people." Norway's prowhaling position comes in part from the political power of fishermen, who used to hunt whales when fish were scarce...
