Researchers have developed a tiny tuning fork device that detects microscopic bacterial vibrations, which could eventually help physicians determine which antibiotics would be most effective in an infected patient. The research team views the discovery as an opportunity for advancement in the medical field, but also a tool that could be used in space exploration. "Our dream is to send something like this to Mars to see if there is life. It's much faster than any other technique one can imagine -- you just put some of the martian dirt inside the liquid and whatever attaches to the cantilever, if it moves it's alive," said biophysicist Giovanni Longo.
