About this episode

This episode explores the feasibility of creating a glowing fish night-light through genetic engineering, examining the science behind bioluminescence and its applications.

Sheldon proposes creating a night-light by inserting glowing jellyfish DNA into a fish—but is that science fiction or real genetic engineering? In this episode, we explore fluorescent proteins, genetically modified animals, and the surprising history of fish that really do glow. The science behind Sheldon’s strange idea helped transform biological research, although it probably would not illuminate your bedroom.
