Researchers have developed a powerful new system called MetaGraph that allows scientists to search through enormous DNA and RNA databases containing more than a quadrillion genetic letters. The tool can rapidly find genetic sequences across global repositories such as the Sequence Read Archive, making it possible to uncover links between genes, microbes, and diseases that were previously hidden within petabytes of raw data.
