Interest in Oxford Nanopore sequencing technology is building in Puerto Rico, according to Jason Williams, principal investigator at Arecibo C3 and associate director of the DNA Learning Center at Cold Spring Harbor Laboratory, who pointed to high symposium attendance as evidence of that growth.^[1] The concrete detail behind that claim: roughly one-third of participants had already gone through training programs run by Arecibo C3 before the event, meaning the organization is not simply drawing curious newcomers but is cycling its own alumni back into deeper engagement.^[2] That figure does not come from an independent headcount - it comes from the same organization that runs the training - but the fraction is specific enough to be checkable.
