2.Raymond Wang,17,of Canada was awarded first place for a device that improves air quality on airplanes while cutting down the spreading of diseases at this year's Intel International Science and Engineering Fair (ISEF).
According to Intel,Wang's system improves the quality of fresh air in a plane cabin by more than 190 per cent,while cutting diseases by up to 55 times,compared to conventional designs.Intel noted that Wang's invention could be easily and economically fixed into existing airplanes.
Two other teen researchers earned awards of﹩50,000 each at the event.One developed a technique to more quickly diagnose diseases caused by HIV.It's the virus responsible for AIDS.The other invented a device to more quickly shut down undersea oil spills.
"Intel believes young people are the key to future innovation and that in order to confront the global challenges of tomorrow,we need students from all backgrounds to get involved in science,technology and engineering,"says Wendy Hawkins,executive director of the Intel Foundation."We hope these winners will inspire other young people to pursue their interest in these fields,"she says,"and apply their curiosity and creativity to the common good."
This year's Intel International Science and Engineering Fair featured approximately 1,700 young scientists selected from more than 75 countries and regions.In addition to the top winners,600 finalists received awards and prizes for their innovative research.
The Intel International Science and Engineering Fair honours the world's most promising student scientists,inventors and engineers.Their projects are then evaluated online by nearly 1,000 judges from almost every scientific field.
The 2015 Intel ISEF is funded jointly by Intel and the Intel Foundation with additional awards and support from dozens of other academic,governmental and scientific organizations.This year,US﹩4 million was awarded.
