Tokyo-based Ko-sin Printing has developed a printing process that allows authors to add a more personal touch to their printed works by using ink that includes their DNA.
Ko-sin also claims it is possible to extract genetic information from materials printed using this process. When the company sent a sample page to a DNA laboratory, the lab technicians were able to isolate and extract the DNA from the page. [Link, via Neatorama]
