So, scientists have managed to make glowing trees.
SCIENCY GOODNESS AHOY
It's been known for a while that chlorophyll releases light when excited by ultraviolet radiation with a 400 nm (nanometer) wavelength. What these researchers did, is they added gold nanoparticles to the leaves. The little spiky nanoparticles absorb different (285 nm) ultraviolet radiation (from the sun, or other sources) and put out 400nm UV light, which then causes chlorophyll.
Since it requires UV radiation to work, I'm not sure what the use is, but someone will surely find a use.
(Coming soon: really, really high-tech red-light districts!)
