Ultrasound waves

What is a human being? What is life? Can science give us reliable answers to such questions? The electricity of life. The meaning of human consciousness. Are we alone? Are the traditional contests between science and religion still relevant? Does the word "spirit" still hold meaning today?

Groundbreaking, Inexpensive, Pocket-sized Ultrasound Device Can Help Treat Cancer, Relieve Arthritis

http://www.sciencedaily.com/releases/20 ... 172050.htm
A prototype of a therapeutic ultrasound device, developed by a Cornell graduate student, fits in the palm of a hand, is battery-powered and packs enough punch to stabilize a gunshot wound or deliver drugs to brain cancer patients. It is wired to a ceramic probe, called a transducer, and it creates sound waves so strong they instantly cause water to bubble, spray and turn into steam.
Lewis miniaturized the ultrasound device by increasing its efficiency. Traditional devices apply 500-volt signals across a transducer to convert the voltage to sound waves, but in the process, about half the energy is lost. In the laboratory, Lewis has devised a way to transfer 95 percent of the source energy to the transducer.
