"Revolutionary 'Heart-on-a-Chip' Unveiled by Scientists"

Scientists have developed a new "heart-on-a-chip" device the size of a credit card, mimicking human heart biology to study heart disease and aid drug discovery. This technology, part of the organ-on-a-chip systems, aims to revolutionize drug development by providing more accurate ways to mimic human organs in the lab, potentially reducing or replacing animal testing. While further refinement is needed, these models have the potential to shift the way new drugs are developed and tested, as recognized by the FDA.
