3D image correlation is a general-purpose strain measurement tool that allows us to measure 3D displacement and the true surface strains of any material without contact and without many of the difficulties associated with these measurements.

Oxford University zoologists Graham Taylor and Adrian Thomas have outfitted an eagle with four miniature high-speed spy cameras and other instruments in a 15 g pack to learn more about its aviational secrets. An inertial measurement unit recorded details of the bird's aerobatics and transmitted the data to a receiver on the ground.

Increasingly strict regulations present a challenge to those shipping magnetized materials. Here's how a Hall effect gaussmeter can help.
