Tossing and turning at night could double the risk of a heart attack People who toss and turn in their sleep are twice as likely to suffer a heart attack, research suggests. Scientists said regular waking in the night should be seen as a warning of future ill-health.The study of nearly 13,000 people found that people who struggled to sleep through the night were 99 per cent more likely to suffer from heart attacks or severe angina. Those who took more than half an hour to fall asleep or got less than six hours of sleep a night were also at increased risk. The Japanese research did not establish why there were such a strong association between sleep and heart health. But scientists said that the act of constant waking might cause “overactivity” in the nervous system, which could raise heart the heart rate and blood pressure, placing extra strain on the heart. Poor sleep could also be a symptom of poor health, meaning that those with heart problems were less likely to get a decent night’s sleep. The research found people who took more than half an hour to fall asleep had a 52 per cent increased heart attack risk and 48 per cent increased risk of a stroke. And those who got less than six hours of sleep a night were 24 per cent more likely to have a heart attack.

Exercise 14

Read the following passage and choose the most appropriate answer from A,B,C or D to answer questions.

Stress is with us all the time. It comes from mental or emotional activity as well as physical activity. It is unique and personal to each of us. So personal, in fact, that what may be relaxing to one person may be stressful to another. For example, if you're a busy executive who likes to keep occupied all of the time, "taking it easy" at the beach on a beautiful day may feel extremely frustrating, nonproductive, and upsetting. You may be emotionally distressed from "doing nothing." Too much emotional stress can cause physical illnesses such as high blood pressure, ulcers, or even heart disease. Physical stress from work or exercise is not likely to cause such ailments. The truth is that physical exercise can help you to relax and to better handle your mental or emotional stress.

A. stressful B. distinctive C. brisk D. relaxing

2. Which of the following people would find "taking it easy" stressful?

A. Construction worker B. Business executive

C. Farm worker D. Truck driver

3. In the fifth sentence, "distressed" most nearly means __________.

A. upset B. distinctive C. relaxed D. active

4. In the eighth sentence, "ailments" most nearly means __________.

A. traits B. episodes C. characteristics D. illnesses

5. Which of the following would be a determinant as to what people find stressful?

A. Personality B. Education C. Marital status D. Shoe size

6. This article, published by the Department of Health and Human Services, probably came from the ____

A. Federal Bureau of Investigation.

B. Alcohol, Drug Abuse, and Mental Health Administration.

C. Education Administration.

D. Communicable Diseases Administration.

7. A source of stress NOT specifically mentioned in this passage is _______.

Nowadays in the news you can read a lot about biotechnology and the controversies about it and perhaps you ask yourself what it is exactly. Well, this article is going to give you a brief history of the field of biotechnology and show you that, although the word “biotechnology” was first used in 1919, we have been using biotechnology for many thousands of years in ways that are completely uncontroversial. It will also look at the more modern developments which have started intense debate. When you are drinking a cold beer on a hot day, or eating a delicious cheese sandwich, you can thank biotechnology for the pleasure you are experiencing. That’s right! Beer, bread and cheese are all produced using biotechnology. Perhaps a definition will be useful to understand how. A standard definition is that biotechnology (or biotech for short) is the application of science and engineering to the direct or indirect use of living organisms. And as you know, the food and drink above are all produced by the fermentation of micro-organisms. In beer, the yeast multiplies as it eats the sugars in the mixture and turns them into alcohol and CO2. This ancient technique was first used in Egypt to make bread and wine around 4000BC! Antibiotics are used to prevent and treat diseases, especially those caused by bacteria. They are natural substances that are created by bacteria and fungi. The first antibiotic was made in China in about 500BC – to cure boils. In 1928 Alexander Fleming discovered penicillin and it was considered a medical miracle. Modern research is looking at the creation of super-antibodies which can kill bacteria and viruses inside the cells that house them. Our modern consumer society produces a lot of waste which needs to be disposed of safely and without harmful end products. Environmental biotechnology can help. Indeed, the use of bacteria to treat sewage was first practiced in 1914 in Manchester, England. Vermiculture or using worms to treat waste is another environmentally-friendly practice and the end product is a natural fertiliser. Bacteria have even been developed to help with problems such as oil spills. They convert crude oil and gasoline into non-toxic substances such as carbon dioxide, water and oxygen and help create a cleaner, healthier environment. These examples of biotechnology are accepted by most people. However, the discovery of the DNA structure by Watson and Crick in 1953 was the beginning of the modern era of genetics and the following areas of biotech are very controversial. Read on… The genetic modification of plants and crops has been in practice for many years. This involves changing the genetic code of these plants so that they are more resistant to bad conditions like drought, floods and frost. Supporters of GM food say that it can offer the consumer better quality, safety and taste and for over a decade Americans have been eating GM food. However, things are very different in Europe where genetically modified food is very strictly regulated and regarded with deep suspicion by the public. GM food has even been called “Frankenfood” in the press, a term inspired by the novel Frankenstein by Mary Shelley. There is a great cultural divide between America and Europe over whether such food is safe to eat and will not harm the environment and the discussion is still in progress. 1997 saw the birth of Dolly the sheep, the first animal cloned from an adult cell. This was a remarkable achievement which created world-wide debate on the ethical issues surrounding cloning. International organisations such as the European parliament, UNESCO and WHO all declared that human cloning is both morally and legally wrong. However, we need to make a distinction between reproductive cloning and therapeutic cloning. Nowadays the idea of reproductive cloning – creating a copy of another person - is no longer interesting for researchers. Instead therapeutic cloning is creating excitement in the biotech world. Key to this technique is stem cells, which are master cells that have the potential to become any other kind of cell in the body e.g. nerve cells, blood, heart muscle or even brain cells. Stem cells themselves have generated a lot of controversy as it was believed that only human embryos could provide them. However, it now appears that adult stem cells offer the same possibility. This would mean that a patient who suffered a heart attack could provide doctors with his adult stem cells which could then be implanted back into his heart and used to create heart muscle, replacing the muscle that was damaged. As the genetic code is identical, there would be no problem of the body rejecting the implant as, unfortunately, happens with organ transplants. In the future, biotechnologists hope that stem cells could be used to grow entire organs. In this way biotechnology offers the hope of revolutionising medical treatment. In this brief overview of the history of biotechnology we have jumped from making bread to making human organs - an enormous leap- and it is clear that these modern practices raise many controversial issues. However, despite the debate, we can imagine that as biotechnology has been around for many years, it will still be around for some time to come - but who knows where it will take us? Questions: After reading, choose the best answer for the following questions 1. What is the main topic of the article? Brief history and modern developments of biotechnology Benefit of biotechnology Modern research in biotechnology 2. What does the pronoun "IT" in the first paragraph refer to? Biotechnology The article The word "Biotechnology" 3. Which products were first made with fermentation of micro-organisms? Beer, bread and cheese Bread and wine Beer and cheese Decide whether the statement below is True or False. 4. Alexander Fleming discovered super-antibodies which can kill bacteria and viruses inside the cells that house them. TrueFalse 5. GM food is easily available in the U.S. and Europe.

Smart children more likely to live longer and stay disease free, study suggests

School swots who faced a ribbing from their classmates for being too brainy will have the last laugh, according to a new study which found high IQ in childhood is linked to a longer life. Researchers at Edinburgh University, Oxford and University College London followed up more than 65,000 people who took part in The Scottish Mental Survey in 1947, aged 11 to find out if intelligence as a youngster had affected their life, and death. They discovered that by the age of 79, having a high IQ lowered the risk of dying from heart disease, stroke, cancer, and respiratory diseases.

"I'm being optimistic about these results,” said Professor Ian Deary, of the University of Edinburgh, who led the research. "I'm hoping it means that if we can find out what smart people do and copy them, then we have a chance of a slightly longer and healthier life. We don't fully know yet why intelligence from childhood and longevity are related, and we are keeping an open mind. Lifestyles (e.g. not smoking), education, health literacy, less deprivation, and genetics might all play a part. We and other research teams are testing these ideas."

The lower risk of death even remained when accounting for factors which could have influenced the results, such as age, sex, and socio-economic status. In fact deprivation, such as unemployment, overcrowding, and other adverse living conditions are thought to account for only about 30 per cent of the IQ-mortality correlation.
