  SAVING THE SOIL More than a third of the Earth’s top layer is at risk. Is there hope for our planet’s most precious resource? A More than a third of the world’s soil is endangered, according to a recent UN report. If we don’t slow the decline, all farmable soil could be gone in 60 years. Since soil grows 95% of our food, and sustains human life in other more surprising ways, that is a huge problem. B Peter Groffman, from the Cary Institute of Ecosystem Studies in New York, points out that soil scientists have been warning about the degradation of the world’s soil for decades. At the same time, our understanding of its importance to humans has grown. A single gram of healthy soil might contain 100 million bacteria, as well as other microorganisms such as viruses and fungi, living amid decomposing plants and various minerals. That means soils do not just grow our food, but are the source of nearly all our existing antibiotics, and could be our best hope in the fight against antibio...

  Cutty Sark:  the fastest sailing ship of all time The nineteenth century was a period of great technological development in Britain, and for shipping the major changes were from wind to steam power, and from wood to iron and steel. The fastest commercial sailing vessels of all time were clippers, three-masted ships built to transport goods around the world, although some also took passengers. From the 1840s until 1869, when the Suez Canal opened and steam propulsion was replacing sail, clippers dominated world trade. Although many were built, only one has survived more or less intact:  Cutty Sark , now on display in Greenwich, southeast London. Cutty Sark ’s unusual name comes from the poem  Tam O’Shanter  by the Scottish poet Robert Burns. Tam, a farmer, is chased by a witch called Nannie, who is wearing a ‘ cutty sark ’ – an old Scottish name for a short nightdress. The witch is depicted in  Cutty Sark ’s figurehead – the carving of a woman typically at...

  Book Review The Happiness Industry: How the Government and Big Business Sold Us Well-Being By William Davies ‘Happiness is the ultimate goal because it is self-evidently good. If we are asked why happiness matters we can give no further external reason. It just obviously does matter.’ This pronouncement by Richard Layard, an economist and advocate of ‘positive psychology’, summarises the beliefs of many people today. For Layard and others like him, it is obvious that the purpose of government is to promote a state of collective well-being. The only question is how to achieve it, and here positive psychology – a supposed science that not only identifies what makes people happy but also allows their happiness to be measured – can show the way. Equipped with this science, they say, governments can secure happiness in society in a way they never could in the past. It is an astonishingly crude and simple-minded way of thinking, and for that very reason increasingly popular. Those who ...

  Whatever happened to the Harappan Civilisation? New research sheds light on the disappearance of an ancient society A The Harappan Civilisation of ancient Pakistan and India flourished 5,000 years ago, but a thousand years later their cities were abandoned. The Harappan Civilisation was a sophisticated Bronze Age society who built ‘megacities’ and traded internationally in luxury craft products, and yet seemed to have left almost no depictions of themselves. But their lack of self-imagery – at a time when the Egyptians were carving and painting representations of themselves all over their temples – is only part of the mystery. B ‘There is plenty of archaeological evidence to tell us about the rise of the Harappan Civilisation, but relatively little about its fall,’ explains archaeologist Dr Cameron Petrie of the University of Cambridge. ‘As populations increased, cities were built that had great baths, craft workshops, palaces and halls laid out in distinct sectors. Houses were a...

  How baby talk gives infant brains a boost A The typical way of talking to a baby – high-pitched, exaggerated and repetitious – is a source of fascination for linguists who hope to understand how ‘baby talk’ impacts on learning. Most babies start developing their hearing while still in the womb, prompting some hopeful parents to play classical music to their pregnant bellies. Some research even suggests that infants are listening to adult speech as early as 10 weeks before being born, gathering the basic building blocks of their family’s native tongue. B Early language exposure seems to have benefits to the brain – for instance, studies suggest that babies raised in bilingual homes are better at learning how to mentally prioritize information. So how does the sweet if sometimes absurd sound of infant-directed speech influence a baby’s development? Here are some recent studies that explore the science behind baby talk. C Fathers don’t use baby talk as often or in the same ways as m...

  The coconut palm For millennia, the coconut has been central to the lives of Polynesian and Asian peoples. In the western world, on the other hand, coconuts have always been exotic and unusual, sometimes rare. The Italian merchant traveller Marco Polo apparently saw coconuts in South Asia in the late 13th century, and among the mid-14th-century travel writings of Sir John Mandeville there is mention of ‘great Notes of Ynde’ (great Nuts of India). Today, images of palm-fringed tropical beaches are clichés in the west to sell holidays, chocolate bars, fizzy drinks and even romance. Typically, we envisage coconuts as brown cannonballs that, when opened, provide sweet white flesh. But we see only part of the fruit and none of the plant from which they come. The coconut palm has a smooth, slender, grey trunk, up to 30 metres tall. This is an important source of timber for building houses, and is increasingly being used as a replacement for endangered hardwoods in the furniture constru...

  MAKING THE MOST OF TRENDS Experts from Harvard Business School give advice to managers Most managers can identify the major trends of the day. But it the course of conducting research in a number of industries and working directly with companies, we have discovered that managers often fail to recognize the less obvious but profound ways these trends are influencing consumers’ aspirations, attitudes, and behaviors. This is especially true of trends that managers view as peripheral to their core markets. Many ignore trends in their innovation strategies or adopt a wait-and-see approach and let competitors take the lead. At a minimum, such responses mean missed profit opportunities. At the extreme, they can jeopardize a company by ceding to rivals the opportunity to transform the industry. The purpose of this article is twofold: to spur managers to think more expansively about how trends could engender new value propositions in their core markets, and to provide some high-level advi...

  Oxytocin The positive and negative effects of the chemical known as the ‘love hormone’ A Oxytocin is a chemical, a hormone produced in the pituitary gland in the brain. It was through various studies focusing on animals that scientists first became aware of the influence of oxytocin. They discovered that it helps reinforce the bonds between prairie voles, which mate for life, and triggers the motherly behaviour that sheep show towards their newborn lambs. It is also released by women in childbirth, strengthening the attachment between mother and baby. Few chemicals have as positive a reputation as oxytocin, which is sometimes referred to as the ‘love hormone’. One sniff of it can, it is claimed, make a person more trusting, empathetic, generous and cooperative. It is time, however, to revise this wholly optimistic view. A new wave of studies has shown that its effects vary greatly depending on the person and the circumstances, and it can impact on our social interactions for wors...
