Predictive analytics are used to identify early warning signs of infection in premature babies before symptoms appear. Large-scale genomic sequencing is also enabling personalized medicine tailored to an individual’s genetic profile. Risks and Ethical Challenges Big data often tells

Despite the benefits, Mayer-Schönberger and Cukier warn of a "dark side":
