| American researchers at Colorado State University have biologically engineered a plant that turns white when it detects even trace amounts of TNT in the air, Fox News reports. The technology could find its way into airports in just a few years. |
据福克斯新闻报道，美国科罗拉多州立大学的研究人员对一种植物进行生物性改造，这样空气中只要稍有三硝基甲苯的气味，它就可以变白。这项技术可在数年之内应用于机场。 |
| "The idea to make detector plants comes directly from nature," said Professor June Medford, the lead scientist on the team. "Plants can't run or hide from threats, so they've developed sophisticated systems to detect and respond to their environment." |
科研组带头人琼·梅德福教授表示：“探测植物的想法直接从自然界得来。植物遇到危险，不能跑也不能躲，所以它们发育出复杂的系统来探测应对环境。” |
| Still relatively immature, the current technology has a response time of hours but Medford hopes to reduce this down to a few minutes over the next couple of years. |
目前的技术相对来说还不成熟，需数小时才能做出反应，梅德福希望在接下来几年里将反应时间缩短到几分钟。 |
| The redesigned plants are 100 times more sensitive than bomb-sniffing dogs. |
经改造的植物比炸弹嗅探犬的灵敏度高出100倍。
