In fourth grade, my best friend and I developed our own sign language so we could communicate across the room and no one would know what we were saying. Unfortunately, our teacher didn't appreciate our "silent" technique. We may have gotten into a lot less trouble if we knew about the reversible data hiding technique developed by Mehmet U. Celik and A. Murat Tekalp of the University of Rochester and Gaurav Sharma and Eli Saber of Xerox. These scientists invented a method for hiding and extracting information within an ordinary digital image. Commonly-used techniques for embedding messages such as digital watermarking irreversibly change the image, resulting in distortions or information loss. "With our new data embedding algorithm, authorized recipients not only can extract the embedded message but also can recover the original image intact," says Sharma. "The technique offers a significantly higher capacity for embedding data and a lower-distortion than any of the alternatives." The technique will be widely applicable to situations requiring authentication of images such as in forensics. It can also be used to encode information about the image itself, such as who took the picture, when, or with what camera.

Enabling the Future is designing prosthetic appendages modeled more like superhero arms and hands than your average static artificial limbs. And they’re doing it through a website and grassroots movement inspired by two men’s design and creation in 2012 of a metal prosthetic for a child in South Africa.
In order to keep an enterprise truly safe from hackers, cyber security has to go all the way down to the device level. Icon Labs is making the point that security has to be built into device components.
Three days after NASA's MAVEN probe reached Mars, India's Mangalyaan probe went into orbit around the red planet. India's first interplanetary mission, and the first successful Mars probe launched by an Asian nation, has a total project cost of nearly $600 million less than MAVEN's.
