DNA sequencing improved by slowing down

21. EPFL scientists have developed a method that improves the accuracy of DNA sequencing up to a thousand times. The method, which uses nanopores to read individual nucleotides, paves the way for better - and cheaper - DNA sequencing. DNA sequencing is a technique that can determine exact sequence of a DNA molecule. One of the most critical biological and medical tools available today, it lies at the core of genome analysis. Reading the exact make-up of genes, scientists can detect mutations, or even identify different organisms. A powerful DNA sequencing method uses tiny, nano-sized pores that read DNA as it passes through.
