(Nature) – The ECHO project emerged from the ashes of the controversial National Children’s Study (NCS), a programme run by the US National Institutes of Health (NIH) that aimed to track 100,000 children from before birth to age 21. The NIH cancelled that study in 2014, after spending more than a decade and US$1.2 billion trying to get it off the ground. ECHO organizers say that their project will be different. By using cohorts that are already under way, they hope to side-step some of the problems that plagued the NCS, which had trouble recruiting participants, defining its hypotheses and sticking to its budget.
