On one level, we have fireflies figured out. We know the enzyme they use to make light (called luciferase), as well as the chemicals they use in the light-generating reaction. We know them so well ...

Unlike the enchanting yellow-green flashes of light produced on warm summer evenings by Photinus pyralis, the most common firefly species in North America, the orange lights of Photinus scintillans ...

Luciferase-based reporter cell lines are invaluable for detecting cellular responses to signaling pathways in vitro, enabling high-throughput screening and profiling of inhibitors or activators. In ...

A new study looks at the development of a firefly's light-emitting organs. Neat, thanks for sharing. Coincidentally, on my other computer screen I'm working with the DNA sequence of firefly luciferase ...
