[EX Q]: Article: Why do we laugh and get amusement from so many different things,from puns   to pratfalls? Why are some things funny to some people and not to others? How is that while a successful joke can cause pleasure,a sick one can cause serious harm? Over the centuries,various scholars have attempted to produce a universally agreed-upon theory of humor.Plato and Aristotle introduced the superiority  theory,the idea that people laugh at the misfortune of others.Their theory seems to explain teasing,but it doesn't work well for knock-knock jokes.Sigmund Freud argued for his relief theory,the concept that humor is a way for people to release psychological tension and reveal their inner fears and desires.His theory works well for dirty jokes,less well for most puns. The majority of humor expels today agree with the incongruity theory,the idea that humor arises when there's a gap between what people expect to happen and what actually happens.Incongruity has a lot going for it -- jokes with unexpected funny lines,for example,fit well.But scientists have found that in comedy,unexpectedness is overvalued. With the goal of developing a new,more satisfactory explanation,I produced "the gentle violation theory",the idea that humor arises when something seems wrong or threatening,but is actually OK or safe.A dirty joke,for example,trades on moral or social violations,but it's only going to get a laugh if the person listening is open enough to consider the subject OK to talk about.Similarly,puns can be seen as linguistic violations that still make grammatical sense. And while most humor theories have struggled to account for tickling  ,or just avoided the phenomenon altogether,my theory accounts for even this kind of laughter.Tickling involves violating someone's physical space in a gentle way.People can't tickle themselves -- because it isn't a violation.

[EX 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. 
 Question: The new study has found that   _  .

[EX Q]: Article: In many sports, physical contact  is part of the game. But when athletes hit their heads, the hit can cause concussions . Concussions have long been a concern for professional athletes, but they've become more common among young players too. Between 2001 and 2009, the number of kids under 19 visiting doctors for concussions each year increased by 62 percent. Engineers are developing new helmets , and new rules are limiting physical contact in some sports. But are these efforts enough to protect kids' brains? Concussions can happen during many types of activities. But sports like football and soccer are especially risky. When you run or jump, your body is moving at an increased speed. A sudden hit causes you to move faster in a different direction. "It's like when you're in a bus and it makes a sudden stop," says Dr. Kevin Crutchfield, an expert at a sports concussion center in Baltimore, Maryland. "You hit the inside of the bus." This hit damages the brain. It affects the way the brain functions. So some sports require athletes to wear helmets. Helmets help reduce the force of a hit. The hard outer shell spreads the force of larger area. Inside a helmet, a plastic or air-filled lining also helps soften the blow. Steve Rowson is an engineer at Virginia Tech. In his lab, he tests how helmets hold up against different types of hits. No helmet can prevent concussions completely, says Rowson. But he's found that when wearing a newer football helmet, the player's head doesn't gain speed as much after a hit. That lowers the risk of concussions. Many youth sports teams have set limits on physical contact to reduce the risk of concussions. In soccer, most concussions happen as a result of headers--shots or passes made with the head. That's why many people think kids shouldn't head the ball until high school. These efforts should help, says Crutchfield. But the best way to prevent long-term brain injuries, he says, is to stop playing immediately if you suffer concussion. "Protect yourself today so you can play again tomorrow."
