Years ago, I was watching a detective show on TV where the fingerprints of a criminal are required. The hero invites the bad guy to his home and offers him a glass of water. The man takes the glass and drinks the water. After he leaves the hero dramatically brings out a handkerchief and picks up the glass. His expressions show the satisfaction at a job well done. The bad guy will soon be arrested. At that time, I found it amazing - how can prints on a glass identify people? My dad explained that if you were to press your thumb on an inkpad and then on a sheet of white paper you will leave a smudge or print, which no one else in the world can make. The same would be true for each of your fingers. The Chinese were the first to use a fingerprint as a type of identification - it was used as a signature on important documents, although they had no way of independently matching it with the owner. Each print is one-of-a-kind and no two people have the same characteristic. Scientists and criminologists (those who study criminal characteristics) determine the differences between fingerprints by a careful study of their curves and not by their general shape or pattern. In 1892, an English scientist, Sir Francis Galton, published a book on using fingerprints to solve crimes. At the same time in Argentina, a police researcher Juan Vucetich was also working towards a fingerprint classification system. However, it was in 1896 that Sir Edward Henry, then serving as Inspector General of Police in India, developed the print classification system that would eventually be used globally. Sir Edward Henry and his assistant Khan Haque discovered that all fingerprints could be systematically classified according to their general curve patterns. He divided them into three classes on the basis of their general pattern: loops , whorls , and arches . By counting the curve between any two points in the pattern, each of the ten fingers could be classified into a particular group. Taking the group together as a unit you have a...

BEIJING - Astronomers have defended against rumors that the terrible earthquake and the following tsunami in Japan were closely related to or even caused by the "supermoon" that will appear in the sky on Saturday. The word "supermoon" was introduced in a report by the British newspaper Daily Mail on March 9, which said amateur scientists were warning that such an astronomical phenomenon could disturb the Earth's climate patterns and may even cause earthquakes and volcanic activity. The moon will be 356,577 kilometers from the Earth on Saturday, the closest in 19 years, and the closest point in its oval orbit coincides with a full moon, the report said. However, Saturday's moon is not actually the closest to Earth in 19 years, Tang Haiming, an astronomer with Shanghai Astronomical Observatory under the Chinese Academy of Sciences, told Xinhua News Agency. A shorter distance of 356,570 km between the two bodies was reached in January 2005, and a distance of 356,566 km was seen in December 2008. Yet some people suggest that previous supermoons have occurred prior to extreme weather events. In 1974 the phenomenon was followed by Cyclone Tracy in Darwin, Australia, and in 2005 it occurred shortly before a deadly tsunami in Indonesia. Coincidentally, two fresh disasters happened in Asia right before Saturday's supermoon. The public's concern about their connection with the moon boomed after Japan's terrible earthquake and tsunami and an earthquake in Southwest China's Yunnan province that killed 25 people on March 10. But astronomers are trying to _ people that such rumors are merely unreasonable. "A supermoon could cause high tides but has no direct relation with natural disasters such as earthquakes," Liu Jie, a researcher with the China Earthquake Network Center, told China Daily on Tuesday. "We can't find any necessary connection between previous supermoons and earthquakes. And the quake in Japan occurred because the Earth's inner energy had accumulated to some extent, and it's not related to the moon. "... What would be the best title for the passage? A) "Supermoon" and earthquake B) The earthquake in Japan . C) Experts clarify worries over "supermoon" D) A rumor about "supermoon"

Question: Can it be true that Australian men spend more time during the week brushing their teeth than they do alone with their children? A new study from the University of the New South Wales has discovered that during the working week, Aussie fathers only spend an average of just over a minute each day alone with their children. Australian mothers, on the other hand, spend three hours a week looking after their children -a much greater disparity than in other countries like America, Denmark, Italy and France, where couples divide the child-care more evenly. These findings will upset those who want to shake off the perhaps unfair image of the Australia as a land of old-fashioned male chauvinism . According to the study, Australian fathers appear to like the fun aspects of parenthood, but shy away from the drudgery. So while they tend to be happy taking the kids to the park or to sports events, they are unlikely to participate regularly in feeding, bathing, or taking the kids to school. In short, parenting is seen as a woman's job and a man's hobby in Australia. Many people believe that in Europe the last twenty years have seen the arrival of the so-called "new man"--the man who is willing to share the housework and child-care. The "new man" never misses his children's school plays and he always gets home in time to read their bedtime story. Indeed, a questionnaire conducted in the UK indicated that almost 70% of British women thought that men were as good at raising children as women. In Australian parenting, _ . A) both fathers and mothers take it as a hobby B) neither fathers nor mothers spend enough time on child-care C) parents don't share the same amount of child-care D) fathers don't like the kids at all
