　　Nanotechnology

　　纳米技术

　　A fab result

　　生物工厂

　　A novel way of making computer memories, using bacteria

　　制造计算机存储器的新奇方法：使用细菌

　　FOR half a century, the essence of progress in the computer industry has been to do more with less.

　　半个世纪以来，计算机产业发展的本质就是花钱更少，成事更多。

　　Moore's law famously observes that the number of transistors which can be 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 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 Intel's resources, there may be a cheaper option—namely to mimic Mother Nature, who has been building tiny devices,

　　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。

　　in the form of living cells and their components, for billions of years, and has thus got rather good at it.

　　对于大自然来说，她建造微小设备已经有数十亿年了，所以自然是信手拈来，当然，这些设备都是以活细胞和其组份的形式呈现。

　　A paper published in Small, a nanotechnology journal, sets out the latest example of the technique.

　　发表在纳米技术期刊《微小》的一篇论文描述了这一新技术的示例，

　　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 in disk drives.

　　该技术团队由英国利兹大学的Sarah Staniland领导，他们用自然生成的蛋白质让微型磁性材料进行排列，这与磁盘驱动器上储存信息的磁性材料排序是类似的。

　　The researchers took their inspiration from Magnetospirillum magneticum, a bacterium that is sensitive to the Earth's magnetic field thanks to the presence within its cells of flecks of magnetite, a form of iron oxide.

　　研究人员从趋磁细菌上获得了灵感，由于该细菌内部存在磁性颗粒，所以对地球磁场非常敏感。
