A team of 10th grade students from Duluth won second place in the 23rd annual Toshiba/National Science Teachers Association ExploraVision science competition.

Avni Kakkar, Jasmine Gao and Sally Pan created the External Microbial Cleansing Device, which has the capability to capture a wide variety of pathogens in the blood stream, deliver enriching nutrients, monitor blood, and develop medical reports. The technology could improve the outcome of those with pathogenic diseases.

The winners got a $5,000 U.S. savings bond and an all-expense paid trip to Washington in June where they will be recognized.
