Question: Article: NANJING -- Another human H7N9 case has been found in east China's Jiangsu Province, the provincial health department confirmed on January 31. The patient, a 75-year-old woman from the provincial capital of Nanjing, is in a critical condition. The case brings the number of infections in the province to eight this year. H7N9 has killed 19 in China this year, and the total number of human infections reached 96 on January 26, according to the Chinese Center for Disease Control and Prevention. With bird flu cases increasing on a daily basis, public concern over people-to-people transmission during Spring Festival is growing. Li Lanjuan, researcher at the Chinese Academy of Engineering and a specialist in H7N9 prevention, said so far there have not been any cases in which one person transmits the flu to another, and the latter transmits the virus to a third person. Her team has identified H7N9 virus mutations this year, but the _ are not large-scale. "Inter-human transmission is very unlikely," said Li, who added that the virus has not evolved to be extensively drug resistant. The National Health and Family Planning Commission said on Wednesday live poultry markets should close if any case of H7N9 avian flu is detected. The southern metropolis of Shenzhen has closed all live poultry markets until February 13 for a thorough cleaning. The city near Hong Kong has reported 14 human H7N9 cases since December 18. Live poultry trading has been halted in Hangzhou, Ningbo and Jinhua cities in Zhejiang, which reported the largest number of human H7N9 cases. China has stepped up research for an H7N9 vaccine in the face of the increasing threat from the virus. Beijing's Snovac Hotech Ltd.,which developed the A/H1N1 and H5N1 vaccines, said in a press release on Wednesday that it has completed preclinical studies of an H7N9 vaccine arid prepared several types for clinical testing. The company has submitted an application to the China Food and Drug Administration to start clinical trials.

Question: Article: Although man has known asbestos for hundreds of years, it was not until 160 years ago that it was mined for the first time on the North American continent. H.W.Johns, owner of a New York City Supply Shop for roofers,was responsible for the opening of that first mine. Mr. Johns was given a piece of asbestos which had been found in Italy. He experimented with the material and then showed its surprising powers to his customers. After putting on a pair of asbestos gloves,which looked much like ordinary work gloves,he took red-hot coals from the fireplace and played with them in his hands. How astonished the customers were to discover that he was not burned at all. You can well imagine that he had increased business in asbestos roofing materials. However,because it was very expensive to transport them from Italy to the United States, Mr. Johns sent out a young scientist to seek a source nearer home. This young man found great vein, in the province of Quebec in Canada. Ever since 1881 Quebec has led the world in the production of this unusual mineral,which is made up of magnesium, silicon, iron, and oxygen. When it is mined, the asbestos is heavy, just as you would expect a mineral to be. When it is separated,a strange thing happens; the rock breaks down into fine, soft, soapy fibers. Scientists do not know why the rock can be separated easily into threads ,but they have found thousands of uses of this fireproof material, of the so- called "cloth of stone."
Answer: A new roofing material
