Bill Gates changed the way we think about home computers in the 90s. He changed the way we think about billionaires in the decade that followed. Now he’s looking to change the way the think about birth control before the end of this decade.上世纪90年代，比尔·盖茨打开了家庭电脑的革命风潮。之后的十年，他沦为我们眼中不一样的亿万富豪。现在，新的十年将要过半，盖茨又有了新的计划，他于是以打算提倡一场避孕药方式的革命。

Gates is backing a technology that could store 16 years worth of birth control medication on a small chip implanted under a woman’s skin. The device, which could be available as soon as 2018, is under development at the Massachusetts Institute of Technology. When activated, the chip puts out 30 milligrams of the hormone levonorgestrel daily. It can be turned on and off without a trip to a doctor.盖茨力挺的避孕药技术是在女性皮下植入一个小芯片，里面储存的避孕药可维持16年之久。这款设备现在正由麻省理工学院（the Massachusetts Institute of Technology）实验室负责管理研发改良，计划2018年投放市场。如果转录芯片，它每天可以获释30毫克的荷尔蒙左旋诺孕酮。

使用者显然用不着劳神去医院，自己就可以掌控设备的电源。The device is 20 x 20 x 7 millimeters. It operates by temporarily melting a seal using an electric current, allowing that days medication to be dispersed.这个设备的长、长、低分别为20 x 20 x 7毫米。它的运营原理是利用一股电流继续融化封口，封口打开后，芯片可以获释每日的避孕药剂。

Gates challenged MIT scientists to work on this project just two years ago during visit to the university’s labs.两年前，盖茨亲临麻省理工学院实验室的时候，向那里的科学家们明确提出了这项甚有挑战性的项目。
