Researchers have found more evidence that suggests a relationship between races and rates(率)of lung cancer among smokers.A new study shows that black people and Native Hawaiians are more likely to develop lung cancer from smoking.It compared their risk to whites, Japanese-Americans and Latinos.
Researchers at the University of Southern California and the University of Hawaii did the new study.The New England Journal of Medicine published the findings.The eight-year research studied more than 180,000 people.They included present and former smokers and people who never smoked.Almost 2.000 people in the study developed lung cancer.
Researchers say genetics(遗传学)might help explain the racial and ethnic(种族的)differences.There could be differences in how people's bodies react to smoke.But environmental influences, including the way people smoke, could also make a difference.
African-Americans and Latinos in the study are reported smoking the fewest cigarettes per day.Whites are the heaviest smokers.But the scientists point out that blacks have been reported to breathe cigarette smoke more deeply than white smokers.This could fill their lungs with more of the chemicals in tobacco that cause cancer.
Scientists know that some diseases effect different groups differently.And some drug companies have begun to develop racially targeted(针对)medicines.Last June, the United States Food and Drug Administration approved a drug designed to treat heart failure in black patients.The name is Bidil.The agency called it“a step toward the promise of personalized medicine.”

When women sit together to watch a movie on TV, they usually talk simultaneously(同时的)about a variety of subjects, including children, men, careers and what's happening in their lives.When groups of men and women watch a movie together, the men usually end up telling the women to shut up.Men can either talk or watch the screen-they can't do both-and they don't understand that women can.Besides, women consider that the point of all getting together is to have a good time and develop relationships-not just to sit there like couch potatoes staring at the screen.
During the ad breaks, a man often asks a woman to explain the plot and tell him where the relationship between the characters is going.He is unable, unlike women, to read the subtle body language signals that reveal how the characters are feeling emotionally.Since women originally spent their days with the other women and children in the group, they developed the ability to communicate successfully in order to maintain relationships.For a woman, speech continues to have such a clear purpose:to build relationships and make friends.For men, to talk is to relate the facts.
Men see the telephone as a communication tool for sending facts and information to other people, but a woman sees it as a means of bonding.A woman can spend two weeks on vacation with her girlfriend and, when she returns home, telephone the same girlfriend and talk for another two hours.
There is no convincing evidence that social conditioning, the fact that girls'mothers talked them more, is the reason why girls talk more than boys.Psychiatrist Dr Michael Lewis, author Social Behaviour and Language Acquisition, conducted experiments that found mothers talked to and looked at, baby girls more often than baby boys.Scientific evidence shows parents res the brain bias of their children.Since a girl's brain is better organized to send and receive speech, we therefore talk to them more.Consequently, mothers who try to talk to their sons are usually pointed to receive only short grunts in reply.
