Sequencing DNA only 100 US$ !

The problem: Learning to sequence DNA fast and cheap might be the most important challenge in health technology. Understanding each patient's full genetic sequencing would give doctors X-Ray vision into their patients' unique makeup and future diseases. There's one big catch. Gene sequencing costs tens of thousands of dollars.

The idea: IBM wants to build a "DNA Transistor" that would be the world's cheapest genetic reader. Scientists refer to the idea as the "$1,000 genome." But IBM says they might be able to get the cost of sequencing down to $100.
