Permanent waterholes in arid Australia are sustained by groundwater. Credit: linders University Australia's future growth is closely aligned to good resources management, and water is top of the list. This is underpinning a growing shortage of groundwater scientists and engineers. The demand is rising, with the National Centre for Groundwater...

A drone carrying a box marked "Flying Sushi" is airborne in the Israeli coastal city of Herzliya. Drone powerhouse Israel is translating the know-how of air force veterans to the delivery of sushi and ice-cream, as companies tap their expertise to avoid collisions in increasingly crowded skies. On a grassy...

The Flow Component Testing Facilities (FCTF) consist of a number of dedicated facilities housed in a single location that are used to perform both standard and custom testing. SwRI engineers will be exhibiting the Institute’s CO2 SSSV testing capabilities, as well as the other FCTF valve testing capabilities, at the...

Stanford PhD candidate Michael John Raitor tests out the augmented cane, created with way-finding capabilities similar to those used in autonomous vehicles.
