  "textContent": "Scientists have discovered that DNA behaves in a surprising way when squeezed through tiny nanopores, overturning a long-held assumption in genetics research. What researchers once thought were knots causing messy electrical signals turn out to be something else entirely: twisted coils called plectonemes, formed as flowing ions inside the pore spin the DNA like a phone cord. These twists can linger and grow as DNA moves through, leaving clear electrical fingerprints.",
