Paparazzi, (狗仔队)or “paps”, are photographers who take pictures of famous people when they are not at the center of public attention. Paps are different from professional photographers or journalists because they never take ordinary photos.

    The goal for paparazzi is to get pictures that no one else will get and then sell the pictures to the buyer who offers the most money — normainly a small newspaper, magazine or website.

    There is no law against paparazzi taking pictures in public places. However, there are laws that protect certain individuals. For example, child protection laws stop improper pictures of anyone under 16 from being published.

    There is also no law that stops paparazzi from following celebrities（名人） and taking their pictures either. However, if paps are secretly following them and taking pictures of their faces, they could get into trouble.

    Most paparazzi hang out on streets and hot spots for celebrities, waiting for the opportunity to take a picture of a star. Many stay on the streets until the early hours of the morning when celebrities are leaving nightclubs and looking a little worse for wear. However, some have other ways to make sure they get pictures. Many paps are in contact with “informers” who know the locations of celebrities at any given time. They then pass the information on to paparazzi. An informer could be anyone — from a restaurant waiter to a salesman.

    Most of the time, paparazzi get a bad reputation for following celebrities. But sometimes stars or their managers will contact paps themselves and tell them exactly where and when they will go. What a love-hate relationship between paparazzi and celebrities!

    One form of social prejudice against older people is the belief that they cannot understand or use modern technology. Activities like playing computer games, going on the Net and downloading MP3s are only for the youngsters. Isn't it unfair that older people enjoying a computer game should be frowned（皱眉）upon by their children and grandchildren?

    Nowadays older people have more control over their lives and they play a full part in society. Moreover, better health care has left more people in their sixties and seventies feeling fit and active after retirement. Mental activity, as well as physical exercise, can contribute to better health. Playing computer games is a very effective way of exercising the brain.

    When personal computers were first introduced, most older people didn't believe they would ever familiarize themselves with it. Now computers have been around for a few generations and retired people have gradually become more relaxed about using them for fun. Gamers over 65 prefer playing puzzle games and card games. Kate Stevens, aged 72, says: “I find it very relaxing. It's not very demanding, but you still need to concentrate.”

    Another development that has favored “grey games” is a change in the type of videogames available on the market. There's a greater variety of games to choose from, including more intellectual and complex strategy（策略）and simulation（模拟）games. Internet Chess and Train Simulator are among the most popular of these. Train Simulator is based on real-world rail activities. Players can choose from a variety of challengers, such as keeping to a strict-timetable and using helper engines during a winter storm.

    Some people argue that “grey gamers” simply don't have the skills required for computer games, and that teenagers are better.  This couldn't be further from the truth. Most computer games require the kind of analytical thinking that improves with practice, which means that the “grey gamers: may well be far better than gamers half a century younger than them. In games where speed is the main consideration, older people would be at a disadvantage because they may have slower reaction time. On the other hand, “grey gamers” have a preference for shower paced, mind challenging games.

    “Freelance retail consultant” refers to daigou in Chinese, or overseas people who buy goods for customers in the Chinese mainland.

     It's estimated that there are 40,000 daigou in Australia, most of whom are young migrants or international students looking for ways to help cover their rent and university cost.

    These freelance retail consultants have created thousands of trading routes, both small and big, into China.

    Shops in Australia sold out of instant formula （婴儿配方奶粉）, leaving many Australian parents unable to buy their preferred brands. The Sydney Morning Herald reported last year that half of Australia's infant formula sold went to China through customers selling to other customers.

    Because of this, daigou have received criticism from Australian media. The Sydney Morning Post even suggested that the Australian government should put a limit on instant formula exports.

    However, not everyone dislikes daigou. “We think daigou are good for the local economy and they are very good for our business,” Peter Nathan, the chief executive of A2 Milk, a New Zealand infant formula maker, told Reuters. “We clearly believe they are a positive force.”

    Others agree that nothing is wrong with the practice. “People are buying these products legally on the Australian market… they're not illegally being exported to China,” Tim Foulds, head of research at Euro monitor Australia and New Zealand, told The Washington Post.

    If you are taking vitamin supplements to reduce your risk of heart disease or cancer, a group of health experts want you to know that those vitamins may actually increase your risk of cancer.

The US Preventive Services Task Force came to this conclusion after reviewing dozens of studies. Nearly half of adults in the US take at least one vitamin or mineral supplement on a regular basis. These pills are advertised as a way to promote general health. In some cases, producers promote them as cancer fighters and heart protectors.

    Studies in animals and in laboratory dishes suggest that oxidative(氧化性的) stress contributes to diseases like cancer and heart disease. If so, there is a reason to believe that antioxidants—including beta－carotene, vitamins A, C, and E—could be useful as preventive medicines.

    But when the Task Force examined the medical evidence on vitamins, it found "inadequate(不充分的) evidence" to support the claims that vitamin and mineral supplements benefit healthy adults.

    "Cardiovascular(心血管的) disease and cancer have a significant health impact in America, and we all want to find ways to prevent these diseases，" Dr. Virginia Moyer, who heads the Task Force, said in a statement. But so far, she added, the medical evidence does not show that taking vitamins is helpful in this aspect.

    However, the Task Force did find "adequate evidence" that people with a raised risk for lung cancer actually increase their risk further by taking beta－carotene, a precursor of vitamin A.

The Task Force recommendations of taking vitamins regularly apply to healthy adults aged 50 and older who don't have "special nutritional needs". The advice does not apply to children, women who are pregnant or may become pregnant, people with chronic illnesses, or people who have to take supplements because they can't get all their essential nutrients from their diet.

    Steven Spielberg's 2002 science-fiction thriller Minority Report produced a world where computers could read minds and predict the future. It seemed fanciful at the time, but fantasy is edging closer to fact.

    On Jan 31, a team of scientists at UC Berkeley, led by Robert Knight programmed computers to decode (破译) brain waves and replay them as words. Five months earlier, another group of Berkeley scientists showed their colleagues short movies and used computers to play back in color what people saw.

    These experiments are a big advance from 2006, when a French scientist first replayed images from a human mind, a black-and-white checkerboard pattern. The possibilities are great: a disabled person could" speak"; doctors could access the mind of a patient who fainted; you could rewatch your dreams on an iPad. There are, of course, equally dark side, such as the involuntary take out of information from the brain.

    In spite of these breakthroughs, Jack Gallant, the neuroscientist who led the first Berkeley team, says current technology for decoding brain activity is still "relatively primitive". The field is held back by its poor machinery, in particular the FMRI.

    "Eventually," says Gallant, "someone will invent a decoding machine you can wear as a hat." Such an advance into the human mind, he says, might take 30 years.

    Still, the recent advances at Berkeley offer small answers, which scientists can use to begin unlocking the secrets of memory and consciousness.
