A Gay BiologistMolecular biologist Dean
Hamer has blue eyes, light brown hair and a good sense of humor. He smokes
cigarettes, spends long hours in an old laboratory at the US National Institute
of Health, and in his free time climbs up cliffs and points his skis down steep
slopes. He also happens to be openly, matter-of-factly gay.
What is it that makes Hamer who he is? What, for that matter, accounts for the
talents and traits that make up anyone's personality? Hamer is not content
merely to ask such questions: he is trying to answer them as well. A pioneer in
the field of molecular psychology, Hamer is exploring the role of genes in
governing the very core of our individuality. To a remarkable extent, his work
on what might be called the gay, thrill-seeking and quit-smoking genes reflects
how own genetic predispositions. That work, which has appeared
mostly in scientific journals, has been gathered into an accessible and quite
readable form in Hamer's creative new book, Living with Our Genes. "You have
about as much choice in some aspect of your personality," Hamer and co-author
Peter Copeland write in the introductory chapter, "as you do in the shape of
your nose or the size of your feet". Until recently, research
into behavioral genetics was dominated by psychiatrists and psychologists, who
based their most compelling conclusions about the importance of genes on studies
of identical twins. For example, psychologist Michael Bailey of Northwestern
University famously demonstrated that if one identical twin is gay, there is
about a 50% likelihood that the other will be too. Seven years ago, Hamer picked
up where the twin studies left off, homing in on specific strips of DNA that
appear to influence everything from mood to sexual orientation.
Hamer switched to behavioral genetics from basic research, after receiving his
doctorate from Harvard, he spent more than a decade studying the biochemistry of
a protein that cells use to metabolize heavy metals like copper and zinc. As he
was about to turn 40, however, Hamer suddenly realized he had learned as much
about the protein as he cared to. "Frankly, I was bored," he remembers, "and
ready for something new." Homosexual behavior, in particular,
seemed ripe for exploration because few scientists had dared tackle such an
emotionally and politically charged subject. "I'm a gay," Hamer says with a
shrug, "but that was not a major motivation. It was more of a question of
intellectual curiosity—and the fact that no one else was doing this sort of
research."
单选题Water Pollution The demand for freshwater rises continuously as the world's population grows. From 1940 to 1990 ,withdrawal of fresh water from rivers, lakes, reservoirs, and other sources has increased fourfold. Of the water consumed each year,69 percent is used for agriculture,23 percent for industry, and 8 percent for domestic uses. Sewage, industrial wastes, and agricultural chemicals such as fertilizers and pesticides are the main causes of water pollution. In 1995,the US Environmental Protection Agency(EPA). reported that about 37 percent of the country's lakes and estuaries, and 36 percent of its rivers, are too polluted for basic uses such as fishing or swimming, during all or part of the year. In developing nations, over 95 percent of urban sewage is discharged untreated into rivers and bays, creating a major human health hazard. Water runoff carries fertilizing chemicals such as phosphates and nitrates from agricultural fields and yards into lakes, streams, and rivers. These combine with the phosphates and nitrates from sewage to speed the growth of algae, a type of aquatic plant. The water body may then become choked with decaying algae, which severely depletes the oxygen supply. This process can cause the death of fish and other aquatic life. Runoff also carries toxic pesticides and urban and industrial wastes into lakes and streams. Erosion, the wearing away of topsoil by wind and rain, also contributes to water pollution. Soil and silt washed from logged hillsides, plowed fields, or construction sites, can clog waterways and kill aquatic vegetation. Even small amounts of silt can eliminate desirable fish species. For example, when logging removes the protective plant cover from hillsides, rain may wash soil and silt into streams, covering the gravel beds that trout or salmon use for spawning. The marine fisheries supported by ocean ecosystems are an essential source of protein, particularly for people in developing countries; approximately 950 million people worldwide consume fish as their primary source of protein. Yet pollution in coastal bays, estuaries, and wetlands threatens fish stocks already depleted by over fishing. In 1989,260,000 barrels of oil was spilled from the oil tanker Exxon Valdez into Alaska's Prince William Sound, a pristine and rich fishing ground. In 1992 there were 8,790 reported spills in and around U.S. waters, involving 5.7 million liters(1.5 million gallons)of oil.
