MIT researchers have figured out how to infuse common plants like watercress and arugula with luciferase, the chemical that makes fireflies glow. The process make the plants emit a dim glow for up to four hours.
Previous efforts to create light-emitting plants have relied on genetically engineering plants to express the gene for luciferase, but this is a laborious process that yields extremely dim light. Those studies were performed on tobacco plants and Arabidopsis thaliana, which are commonly used for plant genetic studies. However, the method developed by Strano’s lab could be used on any type of plant. So far, they have demonstrated it with arugula, kale, and spinach, in addition to watercress.
For future versions of this technology, the researchers hope to develop a way to paint or spray the nanoparticles onto plant leaves, which could make it possible to transform trees and other large plants into light sources.
“Our target is to perform one treatment when the plant is a seedling or a mature plant, and have it last for the lifetime of the plant,” Strano says. “Our work very seriously opens up the doorway to streetlamps that are nothing but treated trees, and to indirect lighting around homes.”

The Bank of England has unveiled its new £50 notes, which had been earmarked to honour a distinguished British scientist, and which will feature Alan Turing, the WWII hero who discovered many of the foundational insights to both modern computing and cryptography, and whose work with the codebreakers of Bletchley Park are widely believed to […]
The great science purge, they’ll call it one day. Donald Trump is closing science offices throughout the federal government. ‘As of June, around 85 percent of all scientific posts in the federal government, including an official scientific advisor to the President, were left unfilled,’ write the editors of I F***ing Love Science blog in an […]
With enough practice and commitment, anyone can be a visual artist. But without the right instruction, that time spent honing your skills could seem like an eternity. If you really want to see where your talent can take you, you need sound fundamentals – and no matter what discipline or genre you lean toward, the […]
Theoretically, there’s never been an easier time for marketers. The ubiquity of social media means a good word – or a good brand – can spread like wildfire with very little effort. But as limitless as the internet is, there’s a lot of competition and noise to contend with. And the vast graveyard of failed […]
