E. coli bacteria produce a "green" blue dye

In its traditional form, the textiles industry isn't exactly a poster child for eco-friendliness – this is largely due to the widespread use of toxic synthetic dyes. That's why there's an increasing demand for less harmful, natural alternatives. Just such an alternative has recently been developed by scientists at Utah State University, who discovered that E. coli bacteria can produce a deep blue dye known as indigoidine.Read More

Secrets of water-skipping revealed

Skipping stones across water may seem like an innocent children's pastime, but the science behind it has helped to win more than one war. Now, researchers at Utah State University's (USU) College of Engineering are uncovering new insights into the physics of these kinds of water impacts that could have wide applications in the fields of naval, maritime, and ocean engineering.Read More

Cheese-powered dragster sets speed record for vehicle of its class

A cheese-powered dragster designed by researchers at Utah State University (USU) set a new speed record for a vehicle of its type, reaching a shade over 65 mph (104 km/h) at the Utah Salt Flats Racing Association's 2012 World of Speed event in September. No prize Stilton was wasted in the pursuit of glory however, as the vehicle runs on yeast biodiesel derived from the industrial waste of cheese production. Read More

A winning idea for wall-climbing

Last month we told you about a team of Brigham Young University engineering students, who created a clever Batman-inspired wall-climbing system. They were competing in the U.S. Air Force Research Laboratory’s 2012 Service Academy and University Engineering Challenge, in which teams had to design gadgets that would allow soldiers to safely and quickly ascend vertical surfaces. Given that the Brigham Young entry didn’t take first place, however, we thought it only made sense to take a look at the entry that did ... and that would be a little something known as the Personal Vacuum Assisted Climber (PVAC), designed by a team from Utah State University.
