Engineers at the University of California San Diego have developed a nano-sized optical fiber that's sensitive enough to feel the forces generated by swimming bacteria and hear the beating of heart muscle cells. The fiber detects forces down to 160 femtonewtons and sound levels down to -30 decibels.
