A recent study conducted by the Pine Street Foundation showed that a dog’s nose may have the ability to detect cancer. A dog’s nose, which was the “medical device” used as part of the research, is believed to be among the world’s most powerful olfactory(嗅觉的) sensors. The study was conducted with 169 subjects 55 of which had been diagnosed as having lung cancer, 31 have breast cancer and 83 control subjects——people without cancer. During the study, five professionally trained scent dogs were used to distinguish between the breath samples of cancer patients and those who were healthy. With an average of 90% accuracy, the research was deemed a success.

The Pine Street Foundation conducted its research on the belief that cancer cells give off a different type of metabolic(新陈代谢) waste product than normal cells. According to the study, the difference is so great that it can be detected by a dog’s sense of smell, including both early and late stages of the disease.

In the conclusion of the study the Pine Street Foundation said that even ordinary dogs may be trained to identify the presence of cancer with only a breath sample. The organization also said that dogs can recognize the disease with astonishing amount accuracy and, finally, that the dog’s detection was not hindered(妨碍) by the presence of age, smoking or stage of cancer.

The Pine Street Foundation plans to continue their research and is currently seeking funding to launch new studies.

A. One of the biggest science stories last year was the research on stem cells announced by South Korean scientist Hwang Woo-suk. But now it appears that the research was false. In June, Mr. Hwang reported that he and his team at Seoul National University had created eleven new stem cell lines.
B. Another major science story last year came from the United States. On December twentieth, a federal judge ruled that teaching “intelligent design” in public schools is a violation of the United States Constitution.
C. There was also news last year about the American space program. The American space shuttle(航天飞机) returned to the skies in July. Discovery and its seven-member crew made the first shuttle flight in two and one-half years. NASA had suspended shuttle flights following the deadly explosion of the shuttle Columbia in 2003.
D. Avian influenza(禽流感) was also a major science story last year. The H5N1 virus appeared in birds in Europe for the first time. Yet the only known human cases of the disease have been in East Asia. There have been about one hundred forty confirmed cases of bird flu since 2003. About half the people have died.

Alzheimer’s disease is a major national health problem. Nearly 2 million Americans over the age of 65 have Alzheimer’s disease. It is a leading cause of death among the elderly. But Alzheimer’s disease is not confined (限于) to the aged. There may be a million or more people under the age of 65 suffering from the disease.

As the disease progresses, the patient may not recognize family and friends. These symptoms(症状) often cause terrible anxiety in the patient. He may feel lost and frightened. Sometimes the patient reacts with wild and bad behavior.

  In the last stages of the disease, the patient may not be able to take care of himself. He may have lost the ability to speak and walk.

  Scientists don’t know exactly what causes Alzheimer’s disease. It may be caused by a virus (病毒).It may be caused by a poisonous substance(物质) in the environment. At present, there is no cure for the disease. But there are ways to slow its progress. Exercise and physical treatment can help the patients of this disease.
