We have a full blown prestige panic; we worry that there wont be enough trophies to go around. Fearful parents urge their children to apply to more schools than ever. U

11、 the number of transistors which can be crammed into a given space _ every 1months. The amount of data that can be stored has grown at a similar rate. Yet as _ get smaller, making them gets harder and more expensive. On May 10th Paul Otellini, the boss of Intel, a big American chipmaker, put the pri
12、ce of a new chip factory at around $10 billion. Happily for those that lack Intels resources, there may be a cheaper optionnamely to mimic Mother Nature, who has been building tiny _, in the form of living cells and their components, for billions of years, and has thus got rather good at it. A paper
13、 published in Small, a nanotechnology journal , sets out the latest example of the _. In it, a group of researchers led by Sarah Staniland at the University of Leeds, in Britain, describe using naturally occurring proteins to make arrays of tiny magnets,similar to those employed to store information
14、 in disk drives.The researchers took their _ from Magnetospirillum magneticum, a bacterium that is sensitive to the Earths magnetic field thanks to the presence within its cells of flecks of magnetite, a form of iron oxide. Previous work has isolated the protein that makes these miniature compasses.
15、 Using genetic engineering, the team managed to persuade a different bacteriumEscherichia coli, a ubiquitous critter that is a workhorse of biotechnologyto _ this protein in bulk. Next, they imprinted a block of gold with a microscopic chessboard pattern of chemicals. Half the squares contained anch
16、oring points for the protein. The other half were left untreated as controls. They then dipped the gold into a solution containing the protein, allowing it to bind to the treated squares, and dunked the whole lot into a heated _ of iron salts. After that, they examined the results with an electron m
17、icroscope. Sure enough, groups of magnetite grains had materialised on the treated squares, shepherded into place by the bacterial protein. In principle, each of these magnetic domains could store the one or the zero of a bit of information, according to how it was polarised. Getting from there to a
18、 real computer memory would be a long road. For a start, the grains of magnetite are not strong enough magnets to make a useful memory, and the size of each domain is huge by modern computing _. But Dr Staniland reckons that, with enough tweaking, both of these objections could be dealt with. The _
19、of this approach is that it might not be so capital-intensive as building a fab. Growing things does not need as much kit as making them.If the tweaking could be done, therefore, the result might give the word biotechnology a whole new meaning. new meaning. A) components B) advantage C) standards D)
20、 compliments E) essence F) inspiration G) disadvantage H) doubles I) solution J) resolution K) devices L) manufacture M) spirit N) product O) technique Nice juicy Apple ALTHOUGH he is still _ things up at Dell, an ailing computer-maker, Carl Icahn has found time to tilt at another tech titan. On Aug
21、ust 13th the veteran shareholder activist _that he had built up a stake in Apple, though he stayed mum about exactly how many shares he had bought. Mr Icahns intentions, however, are crystal clear: he wants the consumer-electronics behemoth to expand plans to return some of its whopping $14billion o
22、f cash and marketable securities to shareholders. Mr Icahn is also after more money at Dell, where he has been lobbying with allies against a _ buy-out plan put forward by Michael Dell, the firms founder, and Silver Lake, a private-equity firm. His pressing has already forced the buy-out group to ra
23、ise its initial offer by over $350m, to $24.billion and he has taken his _ to the courts in a bid to extract an even higher price. Other tech firms have been attracting the attention of activist investors too. Earlier this year ValueAct Capital, an investment fund, said it had built up a $2 billion
