Research finds out why some people are constantly under attack from the bloodsucking insects while others walk free.

    For those unfortunate enough to feature highly on the mosquito hit list, summer nights can be synonymous with mosquito bites. Yet others hardly ever get bitten. So how do the bloodthirsty insects select their victims?

    The insects' tastes may seem arbitrary. However, research shows that when mosquitoes make their choices between potential victims, it all comes down to scent (气味).

    “Mosquitoes are attracted by carbon dioxide and heat, which everyone gives off. But mosquitoes are also attracted by certain scents,” says Karl-Martin Vagn Jensen, the head of research at the Department of Agricultural Science at Arhus University.

    According to Jensen, it has not yet been confirmed exactly what the scents in question are. But research does indicate that some scents are more attractive to mosquitoes than others.

    “All the lab employees rubbed petri dishes (培养皿) against their stomachs. In that way, their scents were put on the dishes, which were then put in a container full of mosquitoes,” he says. “The mosquitoes repeatedly landed on some of the petri dishes, but didn't go anywhere near the others.”

    Perhaps taking inspiration from popular fiction, there are also those who consider garlic as an excellent repellent (驱虫剂) against the winged bloodsuckers. According to the researcher, this strategy may not be entirely fruitless. “As far as I know, there is no scientific proof that eating garlic works. But there may be something to the theory that it's possible to mask scent with garlic,” he says. The only reliable method of protection against mosquitoes is to use repellents that are sold over the counter. It contains some smells that can confuse the mosquitoes. When the mosquito comes closer, it uses smell, heat and carbon dioxide to decide whether to bite. But if it is confused by a repellent, it will never get that far.

    The evidence for harmony may not be obvious in some families. But it seems that four out of five young people now get on with their parents, which is the opposite of the popularly held image of unhappy teenagers locked in their room after endless family quarrels.

    An important new study into teenage attitudes surprisingly shows that their family life is more harmonious than it has ever been in the past.” We were surprised by just how positive today's young people seen to be about their families,” said one member of the research team. “They're expected to be rebellious(叛逆的) and selfish but actually they have other things on their minds; they want a car and material goods, and they worry about whether school is serving them well. There's more negotiation and discussion between parents and children, and children expect to take part in the family decision-making process. They don't want to rock the boat.”

    So it seems that this generation of parents is much more likely than parents of 30 years ago to treat their children as friends. “My parents are happy to discuss things with me and willing to listen to me,” says 17-years-old Daniel Lazall. “I always tell them when I'm going out clubbing. As long as they know what I'm doing, they're fine with it.” Susan Crome, who is now 21, agrees.”Looking back on the last 10 years, there was a lot of what you could call negotiation. For example, as long as I'd done all my homework, I could go out on a Saturday night. But I think my grandparents were a lot stricter with my parents than that.”

    Maybe this positive view of family life should not be unexpected. It is possible that the idea of teenagers' rebellion is not rooted in real facts. A researcher comments, “Our surprise that teenagers say they get along well with their parents comes because of a brief period in our social history when teenagers were regarded as different beings. But that idea of rebelling and breaking away from their parents really only happened during that one time in the 1960s when everyone rebelled. The normal situation throughout history has been a smooth change from helping out with the family business to taking it over.”

    We have encountered a crisis around the corner. You mean global warming? The world economy? No, the decline of reading. People are just not doing it anymore, especially the young. Who's responsible?

Actually, it's more like, what is responsible? The Internet, of course, and everything that comes with it – Facebook, Twitter. You can write your own list.

    There's been a warning about the imminent death of literate civilization for a long time. In the 20th century, first it was the movies, then radio, then television that seemed to spell doom for the written world. None did. Reading survived; in fact it not only survived, it has flourished. The world is more literate than ever before – there are more and more readers, and more and more books.

    The fact that we often get our reading material online today is not something we should worry over. The electronic and digital revolution of the last two decades has arguably shown the way forward for reading and for writing. Take the arrival of e-book readers as an example.

    Devices like Kindle make reading more convenient and are a lot more environmentally friendly than the traditional paper book.

    As technology makes new ways of writing possible, new ways of reading are possible. Interconnectivity allows for the possibility of a reading experience that was barely imaginable before. Where traditional books had to make do with photographs and illustrations, an e-book can provide readers with an unlimited number of links: to texts, pictures, and videos. In the future, the way people write novels, history, and philosophy will resemble nothing seen in the past.

    On the other hand, there is the danger of trivialization. One Twitter group is offering its followers single-sentence-long "digests" of the great novels. War and Peace in a sentence? You must be joking. We should fear the fragmentation of reading. There is the danger that the high-speed connectivity of the Internet will reduce our attention span—that we will be incapable of reading anything of length or which requires deep concentration.

    In such a fast-changing world, in which reality seems to be remade each day, we need the ability to focus and understand what is happening to us. This has always been the function of literature and we should be careful not to let it disappear. Our society needs to be able to imagine the possibility of someone utterly in tune with modern technology but able to make sense of a dynamic, confusing world.

    In the 15th century, Johannes Guttenberg's invention of the printing press in Europe had a huge impact on civilization. Once upon a time the physical book was a challenging thing. We should remember this before we assume that technology is out to destroy traditional culture.
