Robotic eyes can only see so much—some sensors don't operate well in low light, and sonor systems can be confused by polished surfaces. But thanks to a mechanical engineering student, robots that are sent into dangerous locations may soon be able to scurry in the dark like roaches. Owen Y. Loh of Johns Hopkins University has built a man-made antenna that is made of cast urethane and six strain gage sensors that change resistance as they are bent. Like a cockroach's appendage, the antenna sends signals to the robot's controller, enabling it to sense its position relative to the obstacles and maneuver around them.

The promise of the Internet of Things (IoT) is that devices, gadgets, and appliances we use every day will be able to communicate with one another. This potential is not limited to household items or smartphones, but also things we find in our yard and garden, as evidenced by a recent challenge from the element14 design community.
If you didn't realize that PowerPoint presentations are inherently hilarious, you have to see Don McMillan take one apart. McMillan -- aka the Technically Funny Comic -- worked for 10 years as an engineer before he switched to stand-up comedy.
The first Tacoma Narrows Bridge was a Washington State suspension bridge that opened in 1940 and spanned the Tacoma Narrows strait of Puget Sound between Tacoma and the Kitsap Peninsula. It opened to traffic on July 1, 1940, and dramatically collapsed into Puget Sound on November 7, just four months after it opened.
