A solid-state sequencer

This differs from most existing sequencing methods, which read DNA in short snippets that are later stitched together by software. The new system will, at first, complement existing methods, but it could eventually offer cheaper and faster sequencing than other approaches.
Understanding the overall order of DNA sequence on a chromosome is important for studying disease and treating patients, but this big picture can be difficult to get because of the short-snippet approach of most sequencing. Because these methods cannot always figure out how to arrange long repetitive sequences, they can fail to recognize missing sequences, additional sequences, or repeated sequences, all of which can lead to disease.
