Q: Article: It is your sense of smell that quickly tells you there is good food in the kitchen, or your smelly socks need to be washed. But how do we recognize smell? Particular smells turn on certain groups of brain cells , scientists say. When your nose catches a slight smell of something, one of 1,000 different types of odor-receiving cells pick it up. These cells send an electrical signal to a special part of the brain. A group of scientists studied mouse brains using some particular odors like vanilla, apples and fish. They looked at thin slices of each mouse's brain to see which brain cells had been turned on by each odor. The scientists discovered that each odor produces a similar pattern of active cells in different mice. So, a certain combination of cells can tell a mouse that it is smelling vanilla, apples, fish, or any one of the thousands of other smells. Scientists could use studies like this to create a map. It could show which parts of the brain are activated by different smells. Some other scientists, however, say that researchers should also study animals that do not live in a lab, which have spent their lives smelling things in the natural world. With more smelling experience, they might show quite different patterns.

Q: Article: Washington: A research conducted at the University of Maryland looks at the numerous complex reasons as to why young children decide to include or exclude other kids from their group of friends. It suggests that the kids' decision-making process is much more complex than previously believed. "They take into account group information, ranging from cliques and networks, when deciding what makes a group work well. Sometimes kids are excluded because they lack social skills, but a lot of time it has nothing to do with that. Instead it has to do with what we refer to as 'group membership' such as gender, race, nation, and culture," says Professor Melanie Killen, the Associate Director of the Centre for Children Relationships and Culture at Maryland, who led the 4-year project. Reporting their findings in the journal, the researcher said whatever was the reason, individuals who experienced long-term exclusion from the group of friends suffered from depression, anxiety and loneliness. The study looked at two models to define how children make decisions regarding acceptance of other kids in their group -- the individual social _ model and the inter-group social cognition model. While the former says that children's rejection occurs due to social deficits like shyness, wariness or fearfulness, the latter says that it happens because of group dynamics, prejudice and exclusion. It was also found that the age of children was also a factor that influenced their decisions regarding other kids' acceptance as friends. "With age, kids become more aware of group dynamics, conventions, customs, and rituals. With this comes a greater concern about group functioning, which can lead to exclusion which can be negative from a social justice viewpoint," says Killen. The researcher believes that her study may have many benefits, as it could provide insights into how to help when children are rejected by their peers.

Q: Article: As early as the mid-18th century, some people began raising doubts about Marco Polo's travels. In1995, historian Frances Wood argued in her bookDid Marco Polo Go to China? that the famous explorer from Venice never made it to pass the Black Sea. She noted that his travel journal left out the Great Wall of China,chopsticks and tea drinking among other details.Furthermore, Chinese documents from Polo's day made no mention of the explorer and his men. Wood and other scholars have argued that Marco Polo based his tales of China on information collected from fellow trades who had actually been there. Last year, a team of Italian researchers became the latest to challenge Polo's accounts . They said that evidence didn't support his description of Kublai Khan's Japanese invasions . Now, however, research by Hans Ulrich Vogel of Germany's Tubingen University might help prove Marco Polo was true. In a new bookMarco Polo Was in China,the professor of Chinese history tries to prove that Marco Polo spoke the truth. He suggests, for example, that Polo didn't include the Great Wall in his book because it only achieved its great importance in the Ming Dynasty several hundred years later. Vogel further explains that Chinese records from the 13th and 14th centuries avoided setting down visits from Westerners. Historians before him have touched on these issues. But Vogel also relies on another evidence:the explorer's very detailed descriptions of currency and salt production in the Yuan Dynasty. According to Vogel, Polo documented these aspects of Mongol Chinese culture in greater detail than any other of his time. This is a hint that Polo relied on his own powers of observation. Will we ever know whether Marco Polo traveled to China? Perhaps not, but the consequences ofhis real or fictional journey are still felt across the globe.
