Maya Varma has just won the Intel Science Talent Search for innovation for inventing a new device to diagnose chronic lung diseases. What used to mean a hospital appointment now can be done at home with a device costing just $45. But what makes Maya really remarkable is that she's just 17. And she's won $150,000 in one of America's largest and most prestigious high school science competitions for her work, which she described to Newsday.
