Polar bears are being increasingly threatened by the effects of climate change, but their disappearance could have (26) _______ consequences. They are uniquely adapted to the extreme conditions of the Arctic Circle, (27) _______ temperatures can reach -40°C. One reason for this is that they have up to 11 centimetres of fat underneath their skin. Humans with comparative levels of adipose tissue would be considered obese and would be likely to suffer from diabetes and heart disease. (28) _______ the polar bear experiences no such consequences. A 2014 study by Shi Ping Liu and colleagues sheds light on this mystery. They compared the genetic structure of polar bears with (29) _______ of their closest relatives from a warmer climate, the brown bears. This allowed them to determine the genes that have allowed polar bears to survive in one of the toughest environments on Earth. Liu and his colleagues found the polar bears had a gene known as APOB, which reduces levels of low-density lipoproteins (LDLs) - a form of 'bad' cholesterol. In humans, mutations of this gene are (30) _______ with increased risk of heart disease. Polar bears may therefore be an important study model to understand heart disease in humans

Let’s do a little experiment: Take five minutes, and find some information about Angola. How did you get your information? How much information were you able to get? Chances are, you probably just went online and typed the word “Angola”. You were probably able to find out all sorts of things. This experiment shows us how useful the Internet is. Over the last 20 years, the Internet has changed the way that we live, work, and study. The biggest change has been the way that we access information. Twenty years ago, you would have needed an encyclopedia to learn about Angola. If you had wanted information, you would have had to get out of your chair, open your encyclopedia, and look up the word “Angola”. Today all you need is about five seconds and you’ll have the exact same information. This technology makes work a lot faster and more efficient. It has also made information storage a lot easier and neater. Twenty years ago, offices had papers and files all over the place. If you wanted to find a file, you had to open a desk drawer and find the right piece of paper. Today, many of us keep our files in cloud storage. Cloud storage is a technology that lets people store files on the Internet. All you have to do is to sign into the site, and you can find all of your files in seconds. Another big change is communication. These days more and more people are working from home. People have “home offices”. They just do their work at their house and e-mail it to their company. It makes life a lot easier. Some people don’t like these changes. They say that life is too convenient these days, and it is making people lazy. However, most people think that even if this technology makes us a little easier, it still has more benefits than disadvantages. In the end, it doesn’t matter what we think. The Internet has changed all of our lives forever

I first noticed it in a restaurant. The place was oddly quiet, and at one table a group sat with their heads bowed, their eyes hooded and their hands in their laps. I then realised that every one, whatever their age group, was gazing at a handheld phone or tablet. People strolled in the street outside likewise, with arms at right angles, necks bent and heads in awkward postures. Mothers with babies were doing it. Students in groups were doing it. The scene resembled something from an old science fiction film. There was no conversation. Every visit to California convinces me that the digital revolution is over, by which I mean it is won. Everyone is connected. The New York Times last week declared the death of conversation. While mobile phones may at last be falling victim to considerate behaviour, this is largely because even talk is considered too intimate a contact. No such bar applies to emailing, texting, messaging, posting and tweeting. It is ubiquitous, the ultimate connectivity, the brain wired full-time to infinity. The MIT professor and psychologist Sherry Turkle claims that her students are close to mastering the art of maintaining eye contact with a person while texting someone else. It is like an organist playing different tunes with hands and feet. To Turkle, these people are ‘alone together … a tribe of one’. Anyone with 3,000 Facebook friends has none. The audience in many theatres now sit, row on row, with lit machines in their laps, looking to the stage occasionally but mostly scrolling and tapping away. The same happens at meetings and lectures, in coffee bars and on jogging tracks. Psychologists have identified this as ‘fear of conversation’, and have come up hmmm with the term ‘conversational avoidance devices’ for headphones. In consequence, there is now a booming demand for online ‘conversation’ with robots and artificial voices. Mobiles come loaded with customised ‘boyfriends’ or ‘girlfriends’. People sign up with computerised dating advisors, even claim to fall in love with their on-board GPS guides. The ‘post-digital’ phenomenon, the craving for live experience, is showing a remarkable vigour. The US is a place of ever greater congregation and migration, to parks, beaches and restaurants, to concerts, rock festivals, ball games. Common interest groups, springing up across the country, desperately seek escape from the digital dictatorship, using Facebook and Twitter not as destinations but as route maps to meet up with real people Somewhere in this cultural mix I am convinced the desire for friendship will preserve the qualities essential for a civilised life, qualities of politeness, listening and courtesy. Those obsessed with fashionable connectivity and personal avoidance are not escaping reality. They may be unaware of it but deep down they, too, still want someone to talk to.

Stella McCartney was born in 1972, the daughter of pop star Sir Paul McCartney. She is the youngest of three sisters. One sister is a potter and the other sister does the same job as their mother used to do - she works as a photographer. Stella's brother, James, is a musician. Stella first hit the newspaper headlines in 1995 when she graduated in fashion design from art college. At her final show, her clothes were modeled by her friends, Naomi Campbell and Kate Moss, both well-known models. Unsurprisingly, the student show became front-page news around the world. Stella hadn't been in the news before as a fashion designer but she had spent time working in the fashion world since she was fifteen. In March 1997, Stella went to work for the fashion house Chloe. People said the famous fashion house had given her the job because of her surname and her famous parents but Stella soon showed how good she was. She designs clothes which she would like to wear herself, although she's not a model, and many famous models and actors choose to wear them. In 2001 Stella started her own fashion house and has since opened stores around the world and won many prizes. A lifelong vegetarian, McCartney does not use any leather or fur in her design. Instead, she uses silk, wool and other animal-derived fabrics.

A row of mangrove trees sticking out of the sand, exposed by low tide off Kutubdia island in the Bay of Bengal, is all that remains of a coastal village that for generations was home to 250 families. The villagers were forced to flee as their land, which had been slowly eroding for decades, was finally engulfed by the ever-rising tide five years ago. For the embattled people, the distant trees serve as a bittersweet reminder of what they have lost. They also act as a warning of what is to come  UN scientists predict some of the worst impacts of climate change will occur in south-east Asia, and that more than 25 million people in Bangladesh will be at risk from sea level rise by 2050. It is well known that many of the countries most vulnerable to climate change are among those who contribute to it the least, and here that’s certainly true. The carbon footprint of Kutubdia’s 100,000 islanders is small - most do not even have access to a regular electricity supply. But they fear that for them, time is already running out. So far, members of the fishing community of Ali Akbar Dail, perched precariously on a strip of coast next to the embankment, have learnt to adapt to the many natural disasters thrown at them. When the cyclones hit, they hoist their children on to their shoulders and head for the network of cyclone shelters. These shelters, along with the country’s early warning system, have dramatically reduced fatalities. However, after a year that they say has brought more - and more powerful -storms than before, the fishermen are engaged in a battle for survival against their only asset: the ocean. Scientists say the sinking of islands in the Bay in Bengal is due to natural and possibly man-made climate change. Erosion linked to storm surges, for instance, predate global warming. But sea surface temperatures, linked to sea level rise, have risen in the Bay of Bengal. In a report published last month, scientists said they believed the higher surface temperatures in the Indian Ocean were causing cyclones to increase their frequency and intensity. There are too many challenges. People are losing their ancestral land, and they are having to migrate to other places. There, they have to adapt to a new environment. But in their new home, they are still anxious and uncertain about the future.

Many of the major supermarket chains have come under fire with accusations of various unethical acts over the past decade. They've wasted tons of food, they've underpaid their suppliers and they've contributed to excessive plastic waste in their packaging, which has had its impact on our environment. But supermarkets and grocers are starting to sit up and take notice. In response to growing consumer backlash against the huge amounts of plastic waste generated by plastic packaging, some of the largest UK supermarkets have signed up to a pact promising to transform packaging and cut plastic wastage. In a pledge to reuse, recycle or compost all plastic wastage by 2025, supermarkets are now beginning to take some responsibility for the part they play in contributing to the damage to our environment with one major supermarket announcing their plan to eliminate all plastic packaging in their own-brand products by 2023. In response to criticisms over food waste, some supermarkets are donating some of their food surplus. However, charities estimate that they are only accessing two per cent of supermarkets' total food surplus, so this hardly seems to be solving the problem. Some say that supermarkets are simply not doing enough. Most supermarkets operate under a veil of secrecy when asked for exact figures of food wastage, and without more transparency it is hard to come up with a systematic approach to avoiding waste and to redistributing surplus food. Some smaller companies are now taking matters into their own hands and offering consumers a greener, more environmentally friendly option. Shops like Berlin's Original Unverpakt and London's Bulk Market are plastic- tree shops that have opened in recent years, encouraging customers to use their own containers or compostable bags. Online grocer Farmdrop eliminates the need for large warehouses and the risk of huge food surplus by delivering fresh produce from local farmers to its customers on a daily basis via electric cars, offering farmers the lion's share of the retail price.
There is no doubt that we still have a long way to go in reducing food waste and plastic waste. But perhaps the major supermarkets might take inspiration from these smaller grocers and gradually move towards a more sustainable future for us all.

It’s only natural that people want to use the latest innovations to better themselves. Smart devices can truly do incredible things and help to simplify our day. They can also enhance our perceptions, arm us with knowledge, and open up a world of new possibilities. A few people have even decided to make the leap and transform themselves to become cyborgs. Cyborg is a term used to describe a being that is half human and half machine. This may sound like something out of science-fiction novels, but some people have already adapted this lifestyle. One is artist Neil Harbisson. He was bom completely colour-blind, and could only see black and white images. It seemed that he would never experience colour. After attending a cybernetics talk in college, he met an inventor who agreed to make a special device for him. They designed an eyeborg, a mechanical eye that converted colours into sound frequencies. This enabled Harbisson to hear colour and perceive the world in a different way. He started going to museums to ‘"hear” classic paintings. In fact, a simple walk down a grocery store filled with colourful products produces some catchy tunes. Harbisson loves his eyeborg so much that he rarely takes it off. He now gives talks urging others to consider adding their own mechanical improvements. In 1998, British scientist Kevin Warwick conducted his own experiment. He implanted a chip inside of his arm, which he used to control lights and other appliances at home. He later expanded the project by placing electrodes inside his nervous system and linking it to the Internet. This allowed him to control external objects including robotic arms, amplifiers, and. loudspeakers. His work remains influential as this example of extended sensory input was the first of its kind. If you’re interested in becoming a cyborg and you’re willing, a good place to start might be with a pair of Google Glass. Users wear it like ordinary eyeglasses, yet Google Glass is equipped with state-of-the-art electronics. Using voice commands you can have it take a picture of what you see, see directions right in front of you, or translate your voice into other languages. Hopefully, this experience will help you decide whether becoming a cyborg is right for you, or if you’re content to remain a human like the rest of us.

Australians place a high value on independence and personal choice. This means that a teacher or course tutor will not tell students what to do, but will give them a number of options and suggest they work out which one is the best in their circumstances. It also means that they are expected to take action if something goes wrong and seek out resources and support for themselves. Australians are also prepared to accept a range of opinions rather than believing there is one truth. This means that in an educational setting, students will be expected to form their own opinions and defend the reasons for that point of view and the evidence for it. Australians are uncomfortable with differences in status and hence idealise the idea of treating everyone equally. An illustration of this is that most adult Australians call each other by their first names. This concern with equality means that Australians are uncomfortable taking anything too seriously and are even ready to joke about themselves. Australians believe that life should have a balance between work and leisure time. As a consequence, some students may be critical of others who they perceive as doing nothing but study. Australian notions of privacy mean that areas such as financial matters, appearance and relationships are only discussed with close friends. While people may volunteer such information, they may resent someone actually asking them unless the friendship is firmly established. Even then, it is considered very impolite to ask someone what they earn. With older people, it is also rude to ask how old they are, why they are not married or why they do not have children. It is also impolite to ask people how much they have paid for something, unless there is a very good reason for asking.

When you wake up in the morning, do you assume that you're going to have a great day or that you're going to have a difficult day? If you normally have positive expectations, you might consider yourself an optimist, and if your expectations are usually negative, you may be a pessimist. According to research done by the Mayo Clinic, optimism can have a strong positive effect on your health. Their research shows that optimists may live longer, get colds less often, and be less likely to suffer from cardiovascular disease. Optimists may even deal with stress better than pessimists do. If you think you might be a pessimist and would like to try to be more optimistic, pay attention to what some call “self-talk.” The term “self-talk” refers to the automatic thoughts that go through your head all the time. You know-the ideas, worries, beliefs, and hopes that run through your mind as you're driving, washing dishes, folding laundry. Are those thoughts negative like, “Everyone knows so much more than I do,” or positive like, “I'm learning a lot at this job”? If your self-talk is negative, there are some things you can do to steer it in a more positive direction. First, you can simply stop your negative self-talk. Every time you catch yourself thinking something negative, you can stop yourself by actually saying, “Stop,” out loud. Alternatively, you can revise your self-talk. For example, if you catch yourself saying, “I’m terrible at giving presentations,” revise that to a question like, “How can I improve my presentation skills?” Another idea is to think of yourself as a friend. When you “hear” a negative sentence go through your mind, think about whether or not you would feel comfortable saying it to a friend. If the sentence seems too mean to say to a friend, think about what would sound better

"

Having a best friend to confide in can bring a positive effect on our emotional health. An evening out with the closest friend may be the best guarantee of a good time. In fact, our best friend can prevent us from developing serious psychological problems such as depression and anxiety.

Best friendship evolves with time - we cannot go out and pick our best friend. We become friends with people who share common interests – at school or through hobbies, for example.

Best friends have usually known each other for years and stuck together through good and bad times. If you haven't got one, perhaps you are being too distant from people, or focusing too much on your work."

A best friend can ________.
