Biomedical engineers believe they have discovered the physical mechanism that causes high doses of antibiotics to promote the spread of antibiotic resistance between bacteria. The culprit, they say, is an overabundance of 'jumping genes,' called transposons, that carry the genetic instructions for resistance from the cell's source code to plasmids that shuttle between cells.
