Today we review an interview with Professors Harvey Jeffries and Will Vizuete at the University of North Carolina who developed a simulated “lung in a box” into which polluted air and particulates could be injected and tested with lung cells to determine health impacts. In an excellent video, pollution is observed before and after it is “cooked” for a day, resembling the effect of sunshine and warmth added to raw pollution to produce smog with ten times the health impact compared to original air sample. The hope of these inventors is to see these kinds of biological sensors distributed in many cities that experience pollution so that impacts can be readily diagnosed and dealt with.
