Earlier today, a study in Science Translational Medicine proposed that DNA sequencing could become a standard first-choice test for infants in neonatal intensive care units, because a combination of new software and hardware could allow doctors to get results in just 50 hours, answering questions about what is making a baby sick far faster when time is of the essence.
