Q: Yunnan is a province of the People's Republic of China, located in the far southwest of the country. It spans approximately and has a population of 45.7 million (as of 2009). The capital of the province is Kunming, formerly also known as Yunnan. The province borders the Chinese provinces Guangxi, Guizhou, Sichuan, and the Tibet Autonomous Region, and the countries Vietnam, Laos, and Burma. 

Yunnan is situated in a mountainous area, with high elevations in the northwest and low elevations in the southeast. Most of the population lives in the eastern part of the province. In the west, the altitude can vary from the mountain peaks to river valleys as much as . Yunnan is rich in natural resources and has the largest diversity of plant life in China. Of the approximately 30,000 species of higher plants in China, Yunnan has perhaps 17,000 or more. Yunnan's reserves of aluminium, lead, zinc and tin are the largest in China, and there are also major reserves of copper and nickel. 

The Han Empire first recorded diplomatic relations with the province at the end of the 2nd century BC. It became the seat of a Sino-Tibetan-speaking kingdom of Nanzhao in the 8th century AD. Nanzhao was multi-ethnic, but the elite most-likely spoke a northern dialect of Yi. The Mongols conquered the region in the 13th century, with local control exercised by warlords until the 1930s. From the Yuan dynasty onward, the area was part of a central-government sponsored population movement towards the Southwestern frontier, with 2 major waves of migrants arriving from Han-majority areas in northern and southeast China. As with other parts of China's southwest, Japanese occupation in the north during World War II forced another migration of majority Han people into the region. These two waves of migration contributed to Yunnan being one of the most ethnically diverse provinces of China, with ethnic minorities accounting for about 34 percent of its total population. Major ethnic groups include Yi, Bai, Hani, Zhuang, Dai and Miao.

Q: "Can I stay home from school today? I'm ill," he tells his mum. His mother touches his head. "OK, but you will have to look after yourself. I am going to work now," she says. After the front door closes, Jack springs out of bed. He takes off the three warm sweaters he is wearing and puts on a T-shirt and shorts. Then he runs for the kitchen . He is very hungry. After breakfast, Jack turns on the TV. He watches some cartoons and a VCD all the morning. At eleven he calls his friend Tom, who is "ill" too. Tom says he will come over after lunch. The two boys play computer games all the afternoon. Tom has to leave at 4 o'clock, as his mother usually gets home early. Next day, Jack says he feels much better and goes to school. Their Maths teacher Miss Clark says with a smile, "We are having the Maths test now, class. Too many students were at home yesterday."

Q: "Mobile phone killed my man," screamed one headline last year. Also came claims that an unpublished study had found that mobile phones could cause memory loss. And a British newspaper devoted its front page to a picture supposedly showing how mobile phones could heat the brain. 

For anyone who uses a mobile phone, these are worrying times. But speak to the scientists whose work is the focus of these scares and you hear a different story. 

One of the oddest effects comes from the now famous"memory loss" study. Alan Preece and his colleagues at the University of Bristol placed a device that imitated the microwave radiation of mobile phones to the left ear of volunteers. The volunteers were good at recalling words and pictures they had been shown on a computer screen. Preece says he still can't comment on the effects of using a mobile phone for years on end. But he rules out the suggestion that mobile phones have an immediate effect on our cognitive abilities. "I'm pretty sure there is no effect on short-term memory," he says. 

Another expert, Tattersall, remarked that his latest findings have removed fears about memory loss. One result, for instance, suggests that nerve cell synapses exposed to microwaves become more -- rather than less -- receptive to undergoing changes linked to memory formation. 

An even happier outcome would be that microwaves turned out to be good for you. It sounds crazy, but a couple of years ago a team led by William Adey at the Veterans Affairs Medical Center in California found that mice exposed to microwaves for two hours a day were less likely to develop brain tumours when given a cancer-causing chemical. 

"If _ doesn't certainly cause cancer in animals and cells, then it probably isn't going to cause cancer in humans," says William. And while there's still no absolute evidence that mobile phone use does damage your memories or give you cancer, the conclusion is: don't be afraid.
