    It worked. During two summer seasons whilst he held the parasites, his allergy diminished. In W. Herrick, a doctor from Columbia University in New York found a very different link between parasitic worms, or helminths, and allergies.

    Lab workers analysed the gut-dwelling roundworm Ascaris that often caused tenderness and swelling around the fingers and more severe asthma after longer exposure. C Researchers have been trying to make sense of these contradicting findings since the s in the hope of being able to use the power of parasites to help free people of their allergies, without making things worse.

    They know they are playing with fire. After all, helminths are responsible for some truly horrible diseases and cause great suffering around the world. However, as the effects of helminths on the human body become clearer, it looks like their healing powers may have potential benefits. D Not surprisingly, no researchers have been willing to take the risk of deliberately infecting themselves as Turton had done. Instead, most studies are dependent on populations in countries where people are already infected.

    This research tends to emphasize three commonly diagnosed allergic conditions: asthma, eczema and hay fever. The results have been confusing, but now researchers are beginning to have a better understanding.

    E For instance, a study conducted in Taiwan showed that people infected with Enterobius vermicularis, a pinworm that is one of the most common gut parasites in the world, were less likely to have hay fever than the rest of the general population. But the results from Ecuador show a different story.

    Hay fever was not more common in children living in urban areas than it was in children living in rural areas. The parasite was equally common in both groups, so the researchers concluded that something else must be responsible for the prevalence of hay fever.

    F Knowing about eczema has proved as difficult to interpret. For instance, a study in Uganda discovered that eczema was less common among babies whose mothers had been infected with helminths whilst being pregnant. But, another study this time in Ethiopia discovered that children with Trichuris worms, and whipworms that infest the large intestine, were more likely to have eczema than uninfected children.

    But, hookworms decreased the extremity of asthma in a group of Ethiopians and similar benefits have been seen in Brazilian asthma sufferers infected with the Schistosoma Mansoni, the flatworm responsible for schistosomiasis, which damages internal organs. What are we to make of all this? The outstanding link between allergies and parasites is the human immune system. Allergies are caused by an overactive immune response, and helminths have strategies to dampen down our immune response to stimulate their survival.

    After all, they have evolved alongside humans for several thousands of years. H In people with no allergies, foreign material entering the body stimulates the release of cytokines, molecules that sound the alarm to get the attention of other immune cells.

    As immune cells set to attack the intruder, another set of molecules is released to prohibit the immune response from overreacting. One of the main molecules responsible for keeping reactions in check is interleukin, which inhibits the release of certain cytokines. People with allergies tend to have lower than normal levels of interleukin, so their immune responses frequently get out of hand.

    In contrast, people infected with helminths have above-average levels of the molecule, and research on schistosomiasis patients indicates that this is at least partially because of the worms that set free chemicals that trigger the production of interleukin in their host.

    According to a report published by the Carnegie Foundation, non-monetary individual benefits of higher education include the tendency for postsecondary students to become more open-minded, more cultured, more rational, more consistent, and less authoritarian; these benefits are also passed along to succeeding generations Rowley and Hurtado, The Social Value Of Higher Education A number of studies have shown a high correlation between higher education and cultural and family values, and economic growth.

    According to Elchanan Cohn and Terry Geske , there is the tendency for more highly educated women to spend more time with their children; these women tend to use this time to better prepare their children for the future.

    Less Television, Less Violence And Aggression Cutting back on television, videos, and video games reduce acts of aggression among schoolchildren, according to a study by Dr Thomas Robinson and others from the Stanford University School of Medicine.

    The study, published in the January issue of the Archives of Pediatric and Adolescent Medicine, found that third- and fourth-grade students who took part in a curriculum to reduce their TV, video, and video game use engaged in fewer acts of verbal and physical aggression than their peers. The study took place in two similar San Jose, California, elementary schools. Students in one school underwent an lesson, 6-month program designed to limit their media usage, while the others did not.

    Both groups of students had similar reports of aggressive behaviour at the beginning of the study. After the six-month program, however, the two groups had very real differences. The students who cut back on their TV time engaged in six fewer acts of verbal aggression per hour and rated 2. Physical acts of violence, parental reports of aggressive behaviour, and perceptions of a mean and scary world also decreased, but the authors suggest further study to solidify these results.

    Although many studies have shown that children who spend a lot of time on the TV are more likely to act violently, this report further verifies that television, videos, and video games actually cause the violent behaviour, and it is among the first to evaluate a solution to the problem. Teachers at the intervention school included the program in their existing curriculum. Early lessons encouraged students to keep track of and report on the time they spent watching TV or videos or playing Video games, to motivate them to limit those activities on their own.

    For ten days, students were challenged to go without television, videos, or video games. After that, teachers encouraged the students to stay within a media allowance of seven hours per week.

    Almost all students participated in the Turnoff, and most stayed under their budget for the following weeks. Additional lessons encouraged children to use their time more selectively, and many of the final lessons had students themselves advocate reducing screen activities.

    This study is by no means the first to find a link between television and violence. Virtually all of 3, research studies on the subject in the past 40 years have shown the same relationship, according to the American Academy of Pediatrics.

    Among the most noteworthy studies is Dr Leonard D. The more violent television the subjects watched at age eight, the more serious was their aggressive behaviour even 22 years later. Another study by Dr Brandon S. Centerwall found that murder rates climb after the introduction of television. In the United States and Canada, murder rates doubled 10 to 15 years after the introduction of television, after the first TV generation grew up.

    Centerwall tested this pattern in South Africa, where television broadcasts were banned until Murder rates in South Africa remained relatively steady from the mids through the mid- s. The murder rates in the United States and Canada had levelled off in the meantime. The Turnoff did not specifically target violent television, nor did the following allowance period. Reducing television, in general, reduces aggressive behaviour.

    Also, watching television of any content robs us of the time to interact with real people. Watching too much TV may inhibit the shills and patience we need to get along with others without resorting to aggression.

    TV, as a medium, promotes aggression and violence. The best solution is to turn it off. Question Complete the summary using words from the box below.

    If we can believe physicists Anders Nilsson at Stanford University, California, and Lars Pettersson of Stockholm University, Sweden, we could, at last, be getting to the bottom of many of these anomalies.

    Section C Their disputed ideas expand on a theory proposed more than a century ago. The oxygen atom has a slight negative charge whilst the hydrogen atoms share a compensating positive charge. Through this process, the hydrogen and oxygen atoms of neighbouring molecules are drawn to one another, forming a link called a hydrogen bond.

    Section D Hydrogen bonds are even weaker than the bonds that link the atoms within molecules together, so keep going to break and reform, but they are at their strongest when molecules are organized so that each hydrogen bond lines up with a molecular bond.

    The shaping of a water molecule is such that each H20 molecule is surrounded by four neighbours organized in the shaping of a triangular pyramid better known as a tetrahedron. From the conventional view, liquid water has a similar, although less hard, structure, in which extra molecules are able to pack into some of the open gaps in the tetrahedral arrangement. It explains why liquid water is denser than ice — and it seems to comply with the results of various experiments that beams of X-rays, infrared light and neutrons are bounced off samples of water.

    Section E Some physicists had suggested that water placed under certain extreme conditions may separate into two different structures, but most had assumed it resumes a single structure under normal conditions. And then, 10 years ago, a change found by Pettersson and Nilsson called this idea into question. They were using X-ray absorption spectroscopy to research the amino acid glycine.

    Critically, the researchers had got hold of a new, high-power X-ray source with which they could make more sensitive and precise measurements than had ever been possible. They soon knew that the water containing their glycine sample was producing a far more interesting spectrum than the amino acids did.
