Your living room isn't the only place housing a large green Christmas tree with sparkling lights this year. NASA has found a spot in space with its own glowing cosmic tree for the holiday season ...

The science behind glowing plants might not be at streetlight-level yet, but Amirav-Drory and his team hope to inspire the public to help get it there. "The main motivation was to educate," he said.

kickstart the start-up scene in Las Vegas, wants him to engineer a glowing cactus. Amirav-Drory is hopeful they will reach their goal of one day building boulevards lined with glowing trees.

Gene-edited glowing trees, if they can be grown, could theoretically eliminate the need to manufacture that equipment, would require little cost, and zero electricity. They also would be efficient.

Long-term: creating trees that glow so powerfully through bioluminescence that they can function as street lights. Short-term: promoting grassroots innovation within the realm of synthetic biology.

Glowing trees will take awhile to make, but you can already preorder seeds of a glow-in-the-dark Arabidopsis, a little flowering plant of a mustard family.

The trees would have the incident sunlight to work with as the source of energy for their glow, and that dwarfs the streetlight, at 100,000 lumens per square meter.

The golden glow of street lights could soon be replaced by the green fluorescence of tree leaves. Scientists have implanted glowing, sea urchin shaped gold nanoparticles, known as bio light ...
