Holy Smokes! Harvard University researchers have developed a method to encode binary data onto bits of DNA making DNA the densest, most stable storage media ever. The approach they use is actually quite simple even if the enabling technology of DNA sequencing and synthesizing has taken years to develop and perfect. When I read the article and watched this video I could help thinking of the computer in Star Trek.
Obviously this is a long way from being practical in any sense. This work is research and I say very cool research. If you read the comments on the article you will see lots of people slagging the work and pointing out all sorts of problems. People who are poo-pooing this research completely missed the point and are incredibly short-sighted and just plain naïve. Future advances in biochemical based information processing will solve many of the issues the naysayers point out. Researchers will continue to look to nature for answers and they will find them.
