How stupid does one need to be to get a job reading the television news Is it actually beneficial for TV newsreaders to have, instead of a brain, a plate of lemon jelly Last week the debate was raging once again about the controversial and important point as to whether the newsreaders write their own copy, read someone else"s or simply make it up as they go along. Angela Rippon reckonedthat she had never heard of a newsreader writing stuff, but her modern counterpart, the beautiful Sophie Raworth, claims that they do the writing and adds that she has a postgraduate degree in journalism. This is the core of the issue: what on earth is there to learn about journalism at postgraduate level The point and purpose of our lowly, occasionally useful, trade could be scribbled on the back of a postage stamp and would easily be comprehended by a 14-year-old boy with ADHD (attention deficit hyperactivity disorder). Who has decided that it must be dignified with a doctoral thesis Nor is reading the news even what one might call "journalism". It is an even simpler business called "reading". All that the BBC demands of its female newsreaders is an ability to read in an impartial way words like "Israel has murdered more Lebanese children again today" from the teleprompter without belching or lisping. It helps if they have the eminently presentable manner of a girl guide leader from Esher. They are forbidden to express an opinion. They are not required to go undercover, analyze the news or add witty asides. They are required to be that which they are known as in the trade—"a gob on a stick".A penetrating intelligence is not merely unnecessary, it is counterproductive. Newsreaders who are too intelligent soon stop being newsreaders, much as John Humphrys did, stifled by the commonplace of their duties. Or they give the game away by doing what that German newsreader did and end the programme, shaking their heads sadly, muttering, "it"s all lies, all lies". Which is not to say BBC newsreaders are bad at their jobs: quite the reverse. But we should not confuse competence with intelligence. Newsreaders believe that because they are reading out serious stuff and everybody is listening to them, they must therefore be creatures possessed of a high IQ. They are confusing the message with the medium. If the newsreaders are too intelligent, they are likely to _____.

The clean-energy business is turning into the next big investment boom, in which risks are lightly ignored. Until recently, recalls Charlie Gay, a 30-year veteran of the solar-power business, venture capitalists were far too busy catering to captains of the information-technology industry to waste time on "hippy-dippy tree-huggers" like himself. But now the tree-huggers are in the ascendant and theIT barons are busy investing in clean-energy technology. Investors are falling over themselves to finance start-ups in clean technology, especially in energy. Venture Business Research reckons that investment in the field by venture capitalists and private-equity firms has quadrupled in the past two years, from some $500m in 2004 to almost $2 billion so far this year. The share of venture capital going into clean energy is rising rapidly. Clean-energy fever is being fuelled by three things: high oil prices, fears over energy security and a growing concern about global warming. The provision of energy, the industry"s cheerleaders say, will change radically over the coming decades. Polluting coal- and gas-fired power stations will give way to cleaner alternatives such as solar and wind; fuels derived from plants and waste will replace petrol and diesel; and small, local forms of electricity generation will replace big power stations feeding far-flung grids. Eventually, it is hoped, fuel cells running on hydrogen will take the place of the internal combustion engine which is available everywhere. It is a bold vision, but if it happens very slowly, or only to a limited extent, boosters argue that it will still prompt tremendous growth for firms in the business. Analysts confidently predict the clean-energy business will grow by 20-30% a year for a decade. Jef-feries, an investment bank that organized a recent conference on the industry in London, asked participants how soon solar power would become competitive with old-fashioned generation technologies: in 2010, 2015 or 2020. About three-quarters of those present, one visitor happily observed, were "cheque-writers". This "megatrend", the keynote speaker advocated, "may be the biggest job- and wealth-creation opportunity of the 21st century." Such exaggeration might remind people of dotcom bubble. But clean-energy advocates insist growth is sustainable because of the likes of Mr. Schwarzenegger. The Governor is a hero in green circles because of his enthusiasm for environmental regulation. He easily won re-election partly because he seized on global warming as a concern and signed into law—America"s first wide-ranging scheme to cap greenhouse-gas emissions. It can be inferred from the last paragraph that_____.

Parents of children who happily eat what"s put in front of them might assume their kids are well nourished. But two new studies drive home the importance of varying that diet. Deficiencies of vitamin D, omega-3 fats, and other healthful compounds are common; it turns out—and consequential. Growing evidence links vitamin D deficiency not only to weak bones but al-so to impaired immunity, asthma, and diabetes among other problems. And some of the latest research finds that rates of asthma and related respiratory problems climb in kids who are short on other commonly missing essentials, including vitamins C and E and omega-3 fatty acids. A team at the Harvard School of Public Health evaluated the diet and respiratory (relating to the process of breathing) health of some 2,000 North American high school seniors and found that teens who lack of fruit, vegetables, and other healthful foods were most likely to have problems such as coughing, panting, episodes of bronchitis, and asthma. Vitamins C and E, which are abundant in fruit and dark-green vegetables, may "protect the lung from stress," says Harvard research fellow and study leader Jane Burns. Omega-3 reduces inflammation, a key feature of asthma, in which airways swell and make breathing difficult. Oily fish like salmon, mackerel, and tuna—as well as cod-liver oil—are rich in both omega-3 and vitaminD Vitamin D can also be obtained from multivitamin milk and sunshine—and many kids should be getting more of both. In another new study, researchers found that 55 percent of outwardly healthy children and teenagers they tested didn"t have enough vitamin D to grow healthy bones. Dark-skinned children were particularly likely to be short of the bone-building vitamin, according to Babette Zemel, an author of the study and director of the Nutrition and Growth Laboratory at Children"s Hospital of Philadelphia. The melanin (a natural dark brown colour in human skin, hair, and eyes) that makes their skin dark also blocks ultraviolet rays, which the body uses to make vitaminD In winter, when the sun was weakest, more than 90 percent of blacks in the study were vitamin D deficient. Researchers suggest pointing kids outside, and waiting a few minutes before putting on sun block; 10 minutes of midday summer sun provides 10,000 international units of the vitamin—more than enough for a day. Like melanin, sunblock prevents the skin from making vitamin D, so a bit of lotion-free exposure is necessary to grab the benefit. The study on the relationship between diet and respiratory health is to verify that teens _____.
