Magnetic resonance sees the heart beat
Ultrasound is commonly used to look at the heart, but it is unsuitable for the 10-20% of the population that have breathing difficulties (emphysema) or who are medically obese. In both techniques, pat...

Heat can produce ultrasound
Currently most ultrasound devices convert an electrical signal directly into mechanical vibrations through the piezoelectric effect. But these devices only operate over a narrow frequency range and ha...

DNA is a semiconductor
Fink and Schönenberger made their measurements by placing discrete amounts of DNA molecules in a water-based solution. A tiny droplet of the solution was then placed onto a gold-coated carbon foi...
