They glow using a glowing bacteria and with the help of it camouflage itself by mimicking moonlight on the ocean surface.

This glow is believed to serve as a warning to predators ... For example, the green fluorescent protein (GFP) from jellyfish has revolutionized genetic research, allowing scientists to visualize ...

Chalfie asked whether the cloned gene could be expressed in another organism, while Tsien saw long-term potential in making GFP glow brighter so it could be used as an all-purpose biological reporter.

Taking a risk on error-prone PCR, Euskirchen amplified only the GFP coding sequence and inserted it into an expression vector to transform back into E. coli. When Euskirchen imaged her bacteria using ...
