New research is adding to the arsenal of increasingly sophisticated medical imaging tools with a new signal-processing method for viewing muscle activation details never seen before. A novel method using ultrasound imaging, 3-D motion-capture technology and proprietary data-processing software can scan and capture 3-D maps of the muscle structure in just 90 seconds. Previous methods took 15 minutes -- far too long to ask people to hold a muscle contraction.

The precise blending of tiny particles and multicolor dyes transforms gelatin into a realistic surrogate for human tissue. These tissue mimics, known as "phantoms," provide an accurate proving ground for new photoacoustic and ultrasonic imaging technologies.

Integrating a complex, single-crystal material with "giant" piezoelectric properties onto silicon, engineers and physicists can fabricate low-voltage, near-nanoscale electromechanical devices that could lead to improvements in high-resolution 3-D imaging, signal processing, communications, energy harvesting, sensing, and actuators for nanopositioning devices, among others.

A targeted, nanoparticle gelatin-based clot-busting treatment dissolved significantly more blood clots than a currently used drug in an animal study of acute coronary syndrome.

Researchers are using a unique method to interpret and manipulate the pings and echoes that bats, dolphins, and mole rats use for learning about their environments and capturing their prey. With this knowledge, he's created mathematical models that may significantly improve the accuracy of existing medical and navigational technologies.
