Scientists were wrong for decades about DNA knots February 9, 2026
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 […]
