Scientists Build Microbial Map to Trace Where an Object Has Been

Scientists say they have new ways of tracking where clothing, medicines and other items are made, making it harder for unscrupulous businesses to sell items that don't work or violate laws. The new tools are made possible by using machine learning to profile the unique DNA combinations of invisible microbes that vary from place to place. This technology was highlighted at the Milken Institute Global Conference in Los Angeles, as VOA's Elizabeth Lee reports.
