A new machine inspired by a common office toy could one day allow doctors to zap cancerous tumors using "sound bullets," scientists say. Dubbed an acoustic lens, the device could also be used to ...

A laser is shone at the intended target, the bullet is fired, and the chip uses the fins to adjust the bullet's trajectory in mid-flight. It doesn't offer quite the same implications as the totally ...

This article was written by Discover'sAndrew Moseman. Doctors already use concentrated sound waves to see through solid tissue and take a look inside the body, as with ultrasound scans. But in this ...

It's been almost a year since we heard any sort of official update regarding Halo Infinite, the next installment in Microsoft's premiere first-person shooter series. However, that hasn't stopped ...

Sound waves are commonly used in applications ranging from ultrasound imaging to hyperthermia therapy, in which high temperatures are induced, for example, in tumors to destroy them. In 2010, ...
