Tiny Bubbles

Don’t worry, I’m not getting ready to write a post about Don Ho.

Rather, scientists at Baylor College of Medicine have developed a new technique to introduce genes into specific places in the body. They placed DNA for human insulin into tiny, water-insoluble “bubbles,” then injected it into mice. Then, using an ultrasonic pulse aimed at the pancreas, they burst the bubbles in the right place, and the treatment did lead to increased insulin production. Now, the kind of DNA they used (“plasmids”) will not permanently express insulin, but there are ways to make that happen with harmless viruses.

I’d imagine that Doug Melton is none too pleased: diabetes might be able to be cured without using embyronic stem cells or “therapeutic cloning”.
