‘Sound bullets’ aim to improve on ultrasound imaging

Researchers at the California Institute of Technology (Caltech) have built a device that produces highly focused, high-amplitude acoustic signals dubbed "sound bullets." Called a nonlinear acoustic lens, the device could produce acoustic images superior to conventional medical ultrasound imaging, probe for damage in the interior of nontransparent objects like bridges, ship hulls, and airplane wings, and be used to develop non-invasive scalpels – although there’s no word on whether it will enable the development of sonic screwdrivers.

New rust sensor could lead to safer bridges

According to the Neil Young album title, rust never sleeps. In construction, rust damage can be insidious – especially in infrastructure like concrete bridges where rust can have fatal consequences if the steel in bridges fails. But detecting rust before it’s too late has been an ongoing challenge for engineers and scientists. Experts at the Fraunhofer Institute for Microelectronic Circuits and Systems IMS have developed an early-warning system for rust. By installing sensor-transponders into in the concrete to measure the extent of corrosion, engineers are being given a vital heads-up. Read More

Whole lotta shakin' NOT goin' on: the roll-n-cage seismic isolator
