In early 2015, a University of California, San Diego team successfully used micro-motor powered nanobots inside live mice -- without causing damage to their stomach linings, changing healthcare forever. In mid-2015, this concept was quickly advanced by mechanical engineers at Drexel University working in partnership with Daegu Gyeongbuk Institute of Science and Technology (DGIST) in South Korea. What they created were more efficient'micro-swimmers' capable of breaking through clogged arteries and leaving anticoagulant medication to prevent future blockage. Indeed, artificial intelligence (AI), from big data and machine learning to caretaker robots and medical nanobots, can help humans live longer. It's a primary reason scientists have predicted human lifespan to increase to 125 years by 2070.
