[Q]: Article: Conventional wisdom says that hardship can make us old before our time. In fact, a new study suggests that violence not only leaves long-term scars on children's bodies, but also changes their DNA, causing changes that are equal to seven to ten years of premature aging . Scientists measured this by studying the ends of children's chromosomes , called telomeres, says Idan Shalev, lead author of a study published in Molecular Psychiatry. Telomeres are special DNA sequences which prevent the DNA in chromosomes from separating. They get shorter each time a cell divides, until a cell cannot divide any more and dies. Several factors have been found to shorten telomeres, including smoking, radiation and psychological stresses such as being treated badly when young and taking care of a chronically ill person. In this study, researchers examined whether exposure to violence could make children's telomeres shorten faster than normal. They interviewed the mothers of 236 children at ages 5, 7 and 10, asking whether the youngsters had been exposed to domestic violence between the mother and her partner, physical maltreatment by an adult or bullying. Researchers measured the children's telomeres--in cells obtained from the insides of their cheeks--at ages 5 and 10. Telomeres shortened faster in kids exposed to two or more types of violence, says Shalev. Unless that pattern changes, the study suggests, these kids could be expected to develop diseases of aging, such as heart attacks or memory loss, seven to 10 years earlier than their peers. Shalev says there is hope for these kids. His study found that, in rare cases, telomeres can lengthen. Better nutrition, exercise and stress reduction are three things that may be able to lengthen telomeres, he says. The study confirms a smallbutgrowing number of studies suggesting that early childhood hardship imprints itself in our chromosomes, says Charles Nelson, a professor of pediatrics and neuroscience at Harvard Medical School.

[Q]: Article: Let us say there is something you don't know how to do. In the past if you were determined to learn, you might have called friends or s, taken a night class or walked down to the local library for a research term. But now a host of websites are springing up to provide free practical advice on these subjects and actually anything else you can think of. In one sense, these" how - to" sites represent a part of the growing world of online learning. These FAQs(Frequent Answers and Questions), many of which still circulate(go round continuously), took a special subject and explained it to complete _ . But, "how - to" sites take the FAQ idea in a somewhat different direction by addressing subjects that aren't necessarily associated with discussion forums .These sites take the style of a written tutorial and a tone of friendly advice. Possibly the biggest and best known of these sites is learn 2.com(www. learn2. com)It offers nearly 1, 000 free tutorials and adds new ones frequently for a job interview. At ehow. com(www. ehow.)you can learn how to train for your first marathon, how to buy a vacation home, or how to make a movie in eight steps.
Answer: help you to solve any difficulty you meet with

[Q]: Article: A healthy amount of sunshine may be the secret to staying young. British scientists have discovered. Vitamin D is produced naturally by the skin in response to(...) sunlight and may help to slow the ageing process and protect against heart disease, according to the study. Researchers from King's College London studied 2,160 women aged between 18 and 79, looking at their telomeres--- a biological marker of ageing found in DNA. As people get older, their telomeres get shorter and they become more susceptible to certain illnesses. But the study found women with high levels of vitamin D had comparatively longer telomeres--- a sign of being biologically younger and healthier. The study suggests vitamin D may help to slow down the ageing process of DNA, and therefore the ageing process as a whole. Lead researcher Dr Brent Richards said, "These results are exciting because they show for the first time that people who have higher levels of vitamin D may age more slowly than people with lower levels of vitamin D." This could help to explain how vitamin D has a protective effect on many ageing related diseases, such as heart disease and cancer." Professor Tim Spector, a co-author of the report, added, "Although it might sound absurd , it's possible that the same sunshine which may increase our risk of skin cancer may also have a healthy effect on the general ageing process." Vitamin D made by the action of sunlight on the skin accounts for 90 percent of the body's supply, but lower levels can also be got through food such as fish, eggs and breakfast cereals . Other studies have suggested the vitamin plays a key role in protecting against cancer and heart disease.
