Researchers at the Rensselear Polytechnic Institute say they have developed a new kind of liquid lens using only water and high-frequency sound waves to focus light. I’m no expert but I think you could call this a breakthrough that may lead to ultra-sharp consumer lenses. The research has been going on since 2004, funded by a $400,000 grant from the National Science Foundation. Money well spent, I hope. At any rate, this article and its links make for some interesting reading.–David Schonauer
