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.

Athens Olympic 110m hurdle champion Liu Xiang felt so relieved to return to racetrack after getting out of the great number of social activities.

Liu arrived in hometown Shanghai Wednesday night and was about to resume training shortly after.

“I am so exhausted from so many social activities, which made me even more tired than training,” said the 21-year-old Liu, who wrote a new chapter in China’s Olympic history by winning the country’s first ever athletics short-distance running title in the men’s 110m hurdles in Athens in August.

“I am happy that I will resume my training soon back in Shanghai,” said the Shanghai native. He turned into an instant national hero with the Olympic glory and one of the most popular Olympic gold medalists, taking part in scores of celebration activities since he returned to China early September.

“My regular training has been interrupted for such a long time that I think I can only run at about 13.5 seconds now,” said Liu, who clocked a world record-tying time of 12.91 to clinch the title.

“I would rather forget what I have achieved in the past and try my best to realize a higher goal,” he said.

Liu already missed the Berlin Golden League Series on Sunday and won’t be able to catch the IAAF Grand Prix final slated for September 18-19 in Monaco.

He plans on attending an IAAF all-star tournament in Japan at the end of this month.
