When researchers investigated a method to control how DNA moves through a tiny sequencing device, they did not know they were about to witness a display of molecular gymnastics. The researchers found that a positive charge applied to a graphene nanopore speeds up DNA movement, while a negative charge stops the DNA in its tracks. However, the DNA seemed to dance across the graphene surface, pirouetting into sequence-specific shapes they had never seen.
