The cell is the smallest unit of life but still many riddles remain about what goes on inside it. We introduce a new technique that observes a single molecule in the cell. A cutting edge microscope uses laser technology to reveal unanticipated molecular movement. What is this amazing activity, which even disproved a theory proposed by a Nobel Prize winner? We also take a look at a needle that works on the micrometer scale to move and remove tiny quantities of matter in the tiny organelles found in cells. Join us for a closer look at these achievements, coming in quick succession from Japan, and the new discoveries these world-class techniques are making about the internal world of the cell.
