Climbing robot can scale walls on a supersonic stream of air, won't leave fingerprints behind

There are plenty of wall climbing robots roaming the Earth, but few can scale heights as gracefully as this little guy can. Developed by researchers at the University of Canterbury in New Zealand, this bot can wind its way across any glass, metal or cloth terrain, without even touching its pods to the surface. The secret lies in Bernoulli's Principle, which states that as the speed of a fluid increases, its pressure decreases. This phenomenon also applies to streams of air, which, when moving at high speeds around of a circular gripper, can create a vacuum strong enough to hold things without actually touching them. In this case, air shoots out of the robot's feet at more than 2,000 miles per hour, creating enough pressure to lift the craft, while holding it close to the wall. The technology isn't new, but rarely can it support the weight of an entire device -- let alone the extra cargo that this climber's non-contact adhesive pads can hold. Researchers say the supersonic grippers will be available in "some months" and will probably cost "a few hundred dollars." As for the bot itself, Canterbury's engineers envision it being used for industrial inspections -- though the more we think about it, the more we realize just how dirty our windows are.

Willard Boyle, man who revolutionized digital imaging, dies at 86

We have some sad news to share with you today: Willard Boyle, the man who created the imaging technology behind everything from digital cameras to barcode scanners, has died at the age of 86. In 2009, Boyle shared a Nobel Prize in physics for inventing the CCD, which allowed people to capture images in digital format for the first time. It all began way back in 1969, when Boyle and his future co-Laureate, George E. Smith, started laying the groundwork for the CCD while working at Bell Laboratories. Building off of Einstein's photoelectric effect, the two eventually came up with a way to locate and quantify the electrons that are knocked out of orbit every time light strikes silicon. Boyle and Smith used this technology to create their own digital camera in 1970, as well as a TV camera in 1975. Prior to his groundbreaking invention, Boyle spent two years working for NASA's Apollo program and helped develop both the ruby laser and the semiconductor injection laser. The last three decades of Boyle's life were spent in Wallace, Canada, where he grew up and, on May 7th, passed away after battling kidney disease. He's survived by his wife, three children and an indelible legacy.
