  Music and the emotions Neuroscientist Jonah Lehrer considers the emotional power of music Why does music make us feel? One the one hand, music is a purely abstract art form, devoid of language or explicit ideas. And yet, even though music says little, it still manages to touch us deeply. When listening to our favourite songs, our body betrays all the symptoms of emotional arousal. The pupils in our eyes dilate, our pulse and blood pressure rise, the electrical conductance of our skin is lowered, and the cerebellum, a brain region associated with bodily movement, becomes strangely active. Blood is even re-directed to the muscles in our legs. In other words, sound stirs us at our biological roots. A recent paper in  Nature Neuroscience  by a research team in Montreal, Canada, marks an important step in revealing the precise underpinnings of the potent pleasurable stimulus’ that is music. Although the study involves plenty of fancy technology, including functional magnetic...

  The Intersection of Health Sciences and Geography A While many diseases that affect humans have been eradicated due to improvements in vaccinations and the availability of healthcare, there are still areas around the world where certain health issues are more prevalent. In a world that is far more globalised than ever before, people come into contact with one another through travel and living closer and closer to each other. As a result, super-viruses and other infections resistant to antibiotics are becoming more and more common. B Geography can often play a very large role in the health concerns of certain populations. For instance, depending on where you live, you will not have the same health concerns as someone who lives in a different geographical region. Perhaps one of the most obvious examples of this idea is malaria-prone areas, which are usually tropical regions that foster a warm and damp environment in which the mosquitos that can give people this disease can grow. Ma...

  READING PASSAGE 1 You should spend about 20 minutes on  Questions   1-13  which are based on Reading Passage 1 below. Flying tortoises An airborne reintroduction programme has helped conservationists take significant steps to protect the endangered Galápagos tortoise. A Forests of spiny cacti cover much of the uneven lave plains that separate the interior of the Galápagos island of Isabela from the Pacific Ocean. With its five distinct volcanoes, the island resembles a lunar landscape. Only the thick vegetation at the skirt of the often cloud-covered peak of Sierra Negra offers respite from the barren terrain below. This inhospitable environment is home to the giant Galápagos tortoise. Some time after the Galápagos’s birth, around five million years ago, the islands were colonised by one or more tortoises from mainland South America. As these ancestral tortoises settled on the individual islands, the different populations adapted to their unique environments, ...

            The Benefits of Being Bilingual A According to the latest figures, the majority of the world’s population is now bilingual or multilingual, having grown up speaking two or more languages. In the past, such children were considered to be at a disadvantage compared with their monolingual peers. Over the past few decades, however, technological advances have allowed researchers to look more deeply at how bilingualism interacts with and changes the cognitive and neurological systems, thereby identifying several clear benefits of being bilingual. B Research shows that when a bilingual person uses one language, the other is active at the same time. When we hear a word, we don’t hear the entire word all at once: the sounds arrive in sequential order. Long before the word is finished, the brain’s language system begins to guess what that word might be. If you hear ‘can’, you will likely activate words like ‘candy’ and ‘candle’ as well, at least dur...

  The Lost City An explorer’s encounter with the ruined city of Machu Picchu, the most famous icon of the Inca civilsation A When the US explorer and academic Hiram Bingham arrived in South America in 1911, he was ready for what was to be the greatest achievement of his life: the exploration of the remote hinterland to the west of Cusco, the old capital of the Inca empire in the Andes mountains of Peru. His goal was to locate the remains of a city called Vitcos, the last capital of the Inca civilisation. Cusco lies on a high plateau at an elevation of more than 3,000 metres, and Bingham’s plan was to descend from this plateau along the valley of the Urubamba river, which takes a circuitous route down to the Amazon and passes through an area of dramatic canyons and mountain ranges. B When Bingham and his team set off down the Urubamba in late July, they had an advantage over travelers who had preceded them: a track had recently been blasted down the valley canyon to enable rubber to...

  The risks agriculture faces in developing countries Synthesis of an online debate* A Two things distinguish food production from all other productive activities: first, every single person needs food each day and has a right to it; and second, it is hugely dependent on nature. These two unique aspects, one political, the other natural, make food production highly vulnerable and different from any other business. At the same time, cultural values are highly entrenched in food and agricultural systems worldwide. B Farmers everywhere face major risks, including extreme weather, long-term climate change, and price volatility in input and product markets. However, smallholder farmers in developing countries must in addition deal with adverse environments, both natural, in terms of soil quality, rainfall, etc., and human, in terms of infrastructure, financial systems, markets, knowledge and technology. Counter-intuitively, hunger is prevalent among many smallholder farmers in the devel...
