Handheld DNA scanners coming sooner than expected

Looks like the 2015 timetable for a handheld DNA
scanner has just been accelerated. A company called Thermal Gradient is demonstrating a prototype device which can replicate large amounts of DNA from just a few individual strands such as those found in a drop of blood. What used to require cumbersome lab equipment has been squeezed down to a device half the size of a paperclip capable of processing samples at "unprecedented rates." Oh goodie, let the pre-boarding swab-fest begin!
