Worms Turn Metals into Semi-Conductors
by Jesse Emspak
Worms are useful in the garden and great for fish bait, but one of their talents has remained hidden — until now. Scientists have discovered that worms can manufacture  tiny semiconductors.  
At King’s College in London, researchers fed an ordinary red worm, Lumbricus rubellus, soil laced with metals. The worm produced quantum dots, nano-sized semiconductors that are used in imaging, LED technologies and solar cells. The experiment was published in the Dec. 23 issue of the journal Nature Nanotechnology.
The worms created these electronic components because of their ability to detoxify their body tissue. When worms ingest the metals, proteins in their body shuttle these “toxins” to tissues called chloragogen cells that are similar to a liver in mammals…
