SCIENTISTS from Australia and the United States have found a new way to alter the DNA of bacterial cells through a process used to make many vital medicines including insulin, which is proving to be much more efficient than standard industry techniques.
Instead of opening bacteria cell walls with harsh chemicals or high temperatures to insert DNA, the team used high-frequency radio waves - a much gentler approach that led to many more of the cells taking on the DNA and surviving.
The study published in Nano Letters shows how the new method makes bacterial cells more permeable.
