The flubber of the future? It's under development at the University of North Texas (UNT). The so-called "smart gel" has become the catch phrase for water-based, gelatin-like polymers created in labs. The gels have physical properties that change in response to temperature, light, pH and acidic balances, and electric fields. Dr. Zhibing Hu, an associate professor of physics at UNT, heads the research. His work incorporates different materials on a hydrogel surface so that it can change into a specific pattern when induced by a certain stimulus. Gels made to date show lattice or other surface patterns that remain visible or invisible by simply switching between room and body temperature. Possible future uses for this type of gel include acting as an optical gauge that monitors environmental conditions, such as metal ions in water, or as a miniature sensor that can detect enzyme activity. Toys or signs with designs and wording that appear and disappear in response to changing temperatures also would be a possibility. E-mail email@example.com.
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.
