Arsenic replaces phosphorus!

posted Dec 15, 2010, 6:52 PM by Leanne Harris Dyksterhuis

Researchers in the United States have isolated a bacterium from Mono Lake in California which grows in the presence of high concentrations of arsenic.  The researchers showed that the strain GFAJ-1 of the Halomonadaceae substitutes arsenic for phosphorus in nucelic acids and proteins.  The article is available at the Science journal website.

Green Fluorescent Protein Based Solar Cells

posted Sep 8, 2010, 10:18 PM by Leanne Harris Dyksterhuis

Researchers at Chalmers University of Technology in Gothenburg, Sweden are using GFP to generate solar cells. The team deposit two aluminium electrodes with a tiny gap between them onto a silicon dioxide substrate. A droplet of green fluorescent protein is then added on top, whereupon the protein assembles itself into strands between the electrodes.  When exposed to ultraviolet light, the GFP absorbs photons and emits electrons, which travel around a circuit to produce electricity.  Read more about this at New Scientist magazine.
