Batteries Built by Viruses Not everyone runs from the tiny disease carriers, though3.In Cambridge, Massachusetts4, scientists have discovered that some viruses can be helpful in an unusual way.They are putting viruses to work, teaching them to build some of the worlds smallest rechargeable batteries. Belchers team includes Paula Hammond,who helps put together the tiny batteries, and Yet-Ming Chiang, an expert on how to store energy in the form of a battery.Were working on things we traditionally dont associate with nature. says Hammond. The ideal battery will store a lot of energy in a small package.Right now,Belchers model battery,a metallic disk completely built by viruses,looks like a regular watch battery.But inside,its components are very smallso tiny you can only see them with a powerful microscope. 词汇: microorganism n.微生物 collaborator n.合作者,协作者 注释: 2.steer clear of:避开,绕开 4.Cambridge,Massachusetts:马萨诸塞州的剑桥市。本文第三段提到的the Massachusetts 5.came up with:提出 7.These microbatteries may change the way we look at viruses:这些微型电池可能会改变我们看待病毒的方式。作者想表达的意思是:人们一直认为病毒有害无益,现在病毒可用来制作电池,人们对病毒的看法可能会因此而发生变化。
