Steve Rundell and fellow engineering students at Michigan State University never go thirsty, thanks to the ingenious automatic drink-making machine they designed and built. The contraption allows the "bartender" to select various drink mixtures displayed on an LCD screen. A controller sends a signal to a servo motor that drives a rotating carousel, which positions the drink cup under the appropriate liquid reservoirs. A solenoid valve opens, automatically dispensing a predetermined amount of liquid into the cup.

So it seems fitting that a town in which painter Vincent van Gogh once lived has given him a very Dutch-like tribute -- a bike path lit by a special smart paint in the style of the artist's “Starry Night” painting.
For decades, engineers have worked to combat erosion by developing high-strength alloys, composites, and surface coatings. However, in a new paper, a team at Jilin University in China turned to one of the most deadly animals in the world for inspiration -- the yellow fat-backed scorpion.
