超長(zhǎng)有效16年，比爾.蓋茨力挺皮下植入式避孕芯片.

　　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 bore the end of this decade.

　　上世紀(jì)90年代，比爾?蓋茨開(kāi)啟了家庭電腦的革命風(fēng)潮。之后的十年，他成為我們眼中不一樣的億萬(wàn)富豪?，F(xiàn)在，新的十年即將過(guò)半，蓋茨又有了新計(jì)劃，他正準(zhǔn)備倡導(dǎo)一場(chǎng)避孕方式的革命。

　　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.

　　蓋茨力挺的避孕技術(shù)是在女性皮下植入一個(gè)小芯片，里面儲(chǔ)存的避孕藥可維持16年之久。這款設(shè)備現(xiàn)在正由麻省理工學(xué)院(the Massachusetts Institute of Technology)實(shí)驗(yàn)室負(fù)責(zé)開(kāi)發(fā)改進(jìn)，計(jì)劃2018年投放市場(chǎng)。如果激活芯片，它每天可以釋放30毫克的荷爾蒙左旋諾孕酮。使用者根本用不著勞神去醫(yī)院，自己就可以控制設(shè)備的開(kāi)關(guān)。

　　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.

　　Gates challenged MIT scientists to work on this project just two years ago during visit to the university’s labs.

　　這個(gè)設(shè)備的長(zhǎng)、寬、高分別為20 x 20 x 7毫米。它的運(yùn)行原理是利用一股電流暫時(shí)融化封口，封口開(kāi)啟后，芯片可以釋放每日的避孕藥劑。

　　兩年前，蓋茨蒞臨麻省理工學(xué)院實(shí)驗(yàn)室的時(shí)候，向那里的科學(xué)家們提出了這項(xiàng)頗有挑戰(zhàn)性的項(xiàng)目。
