Bioluminescence. Think fireflies. Or anglerfish. Or your friendly neighborhood boulevard tree. Wha? Yep. Recently the Royal Society of Chemistry published (and gave their royal thumbs-up to) Dr. Yen-Hsun Wu’s paper in which he describes eliminating the need for energy-sapping streetlights by injecting trees with gold nanoshells.

According to inhabitat (design will save the world):

By implanting the gold nanoparticles into the leaves of the Bacopa caroliniana plants, the scientists were able to induce the chlorophyll in the leaves to produce a red emission. Under a high wavelength of ultraviolet light, the gold nanoparticles were able to produce a blue-violet fluorescence to trigger a red emission in the surrounding chlorophyll.

Popular Science is just as psyched:

This ingenious triple threat of an idea could simultaneously reduce carbon emissions, cut electricity costs and reduce light pollution, without sacrificing the safety that streetlights bring.

Creepy? Cool? You decide.

I wonder what will happen to animals that eat the leaves of those trees. Or what will happen to the grass where the leaves fall. Illuminated lawns, perhaps?

That's awesome, it looks like something from the movie Avatar.

I wonder what side effects this has on the plants?

WOW LOTS TO PROCESS I JUST READ A WHOLE ARTICLE ABOUT THE TOPIC OF NANOTECHNOLOGY. NANOTECHNOLOGY SOUNDS A LITTLE CREEPY OF COURSE PEOPLE ARE WORKING ON IT BUT IT STILL SOUNDS REALLY CREEPY SO THIS IS THE PICTURE THE ARTICLE WANTED TO PUT IN MY HEAD: IMAGINE A LITTLE GIRL PUTTING ON SUNSCREEN NOW OF COARSE SHE HAS NO IDEA THAT BILLIONS OF NANOS NOW HAVE THE OPTION OF ENTERING HER BODY THROUGH HER SKIN THE MOTHER OF THE LITTLE GIRL HAS NO IDEA EITHER
