34Batteries Built by Viruses病毒电池
What do chicken pox, mon cold,the flu,and AIDS have mon? They're all disease caused by viruses,tiny anisms that can pass from person to person. It’s no wonder1 that when most people think about viruses, finding ways to steer clear of2 viruses is what's on people's minds. 水痘、普通感冒、流感和艾滋病有哪些相似之处呢?这些都是由病毒引起的疾病。病毒是能够在人与人之间传染的微生物。难怪大部分人一提到病毒,首先想到的是如何躲避病毒。
Not everyone runs from the tiny disease carriers, 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 world’s smallest rechargeable batteries. 然而, 并不是每个人都躲避这些病毒携带者。在马萨诸塞州剑桥市,科学家发现有些病毒能起到非同寻常的作用。他们使病毒开始工作,使病毒构成世界上最小的充电电池。
Viruses and batteries may seem like an unusual pair, but they're not so strange for engineer Angela Belcher, who first came up with5 the idea. At the Massachusetts Institute of Technology (MIT) in Cambridge,she and her collaborators bring together different areas of science in new ways. In the case of the virus-built batteries,the bine what they know about biology,technology and production techniques. 病毒和电池的搭档似乎并不常见,但这对于工程师安吉拉·贝尔彻来说却并不陌生。安吉拉·贝尔彻最早产生了这一想法。在位于剑桥市的麻省理工学院,她和合作者一起用新方式融合了不同的科学领域。在由病毒构成的电池里,科学家融合了他们在生物、技术和生产工艺方面的知识。
Belcher’s 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. "We're working on things we traditionally don’t associate with nature," says Hammond. 贝尔彻的团队包括帮助组装微型电池的宝拉·哈蒙德和以电池形式存储能量的专家蒋业明。哈蒙德说,“我们现在从事的行业是传统中不会想到的。”
Many batteries are already pretty small. You can hold A,C and D batteries6 in your hand. The coin-like batteries that power watches are often smaller than a penny. However,every year,new electronic devices like personal music players or cell phones get smaller than the year before. As these devices shrink,ordinary bakeries won’t be small enough to fit inside. 许多电池已经很小了。A型、C型和D型电池都可以握在手里。硬币形状的手表电池通常比分币还小。然
