6、s of tiny magnets,similar to those employed to store information in disk drives.The researchers took their (6)_ 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 w

7、ork has isolated the protein that makes these miniature compasses. Using genetic engineering, the team managed to persuade a different bacteriumEscherichia coli, a ubiquitous critter that is a workhorse of biotechnologyto (7)_ this protein in bulk.Next, they imprinted a block of gold with a microsco

9、iron salts.After that, they examined the results with an electron microscope.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 inform

10、ation, according to how it was polarised.Getting from there to a 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 (9)_.But Dr Staniland reckons that, with enou

14、 crammed into a given space doubles every 18 months.摩尔定律的著名论断是：能够放入某空间内的晶体管数量每18个月翻一番。The amount of data that can be stored has grown at a similar rate.储存的数据也有着类似的增长速率，Yet as components get smaller, making them gets harder and more expensive.但是随着部件越来越小，它们的制造难度和成本也逐渐增加。On May 10th Paul Otellini, the

15、boss of Intel, a big American chipmaker, put the price of a new chip factory at around $10 billion.5月10日，美国芯片巨头因特尔总裁兼CEOPaul Otellini宣布将花费上百亿美元建设新工厂。Happily for those that lack Intels resources, there may be a cheaper optionnamely to mimic Mother Nature,对于不像因特尔那么有钱的厂家的好消息是，他们或许可以选择更便宜的方式模拟大自然。who has been building tiny devices, in the form of living cells and their components, for billions of years, and has thus got rathe
