A 14-year-old scientist took home $25,000 from a national science competition for inventing a liquid bandage that could replace antibiotics.
一个14岁的科学家发明了一种可替代抗生素的液体绷带，在全国科学竞赛上赢得了25,000美元奖金。

Kara Fan from San Diego, CA was won the 3M Young Scientist Challenge in St. Paul, Minnesota. Fan came up with a nano particle liquid bandage that could replace the overuse of antibiotics and potentially reduce the development of superbugs.
来自加利福尼亚州圣地亚哥的Kara Fan赢得了明尼苏达州圣保罗市的3M青年科学家挑战赛。Fan发明了纳米颗粒液体绷带，能解决抗生素滥用问题，可能会减缓超级细菌的发展。

“I want to show my invention of the nanosilver liquid bandage to more people. I think it is important for more people to be aware of antibiotic-resistance bacteria crisis and do something about it,” Fan said.
Fan说：“我想向更多的人展示我发明的纳米银粒子液体绷带，我认为能让更多的人了解耐药菌危机并采取行动是很重要的。”

The 3M Young Scientist Challenge is a national competition for middle school students that takes place every year. The students are tasked with coming up with an idea or invention that tackles existing issues.
3M青年科学家挑战赛是一年一度的针对中学生的全国竞赛，参赛学生的任务是提出一个解决现有问题的想法或发明。

Ten finalists are chosen to compete for the title of “America’s Top Young Scientist” and a grand prize of $25,000. After being selected, they work with scientists at to make their idea come to life.
10名参加决赛的选手被选出来角逐“美国顶尖青年科学家”的头衔和25,000美元的大奖。决赛选手被选出来之后要和科学家一起将他们的想法付诸实践。

Each contestant is judged on their invention’s creativity, scientific knowledge, persuasiveness and communication, and overall presentation.
要对每位选手的发明创意、科学知识、说服力和沟通力，以及综合阐述进行评判。

Other finalists included Jaya Choudray, who invented an airflow control robot that works to reduce energy consumption in a home, and Caroline Crouchley, who invented a climate-friendly transportation system that would eliminate the need for a diesel engine or electric motors.
其他决赛选手有Jaya Choudray，发明了一个可以减少家庭能源消耗的气流控制机器人；Caroline Crouchley发明了一种气候友好型交通系统，可以省去对柴油机或电动机的需求。

3M holds the competition for students in grades 5-8 because research has shown that their interest in science fades after these years.
