Salmon DNA Used in Data Storage Device

Zothecula (1870348) writes "Scientists from National Tsing Hua University in Taiwan and the Karlsruhe Institute of Technology in Germany have created a "write-once-read-many-times" (WORM) memory device, that combines electrodes, silver nanoparticles, and salmon DNA. While the current device is simply a proof-of-concept model, the researchers have stated that DNA could turn out to be a less expensive alternative to traditional inorganic materials such as silicon."

Cool, but not cool as it initially seems (1)

Reading the original paper: http://apl.aip.org/resource/1/applab/v99/i25/p253301_s1?view=fulltext [aip.org] it seems the researchers utilized the affinity of DNA to metal to create a sandwich of DNA film between 2 electrodes. They are not using the biological storage capability of DNA: i.e. the ability of DNA to store information as a string of nucleotides. Still nice though.
