I would like to see safety studies of ultrasound.<p>It seems we use ultrasound, for example on every baby, and don't have good data to prove that there are no side effects.<p>Yet research like this shows that there clearly <i>are</i> biological effects of sufficiently powerful ultrasound.<p>What if societies lack of future Einstein's is down to blasting the brains of all of them with ultrasound pre-birth?
