Prisoners pose an age-old dilemma for societies: try to keep them separated from the good citizenry while possibly easing some of the black sheep back into the fold. Now Malaysian architecture students have hit upon the solution of a sky prison city that allows prisoners to work in farms and factories to contribute to the host city below, CNET reports.
Measuring sensors and actuators can turn any old hip implant into a smart network that helps patients avoid implant problems and may even actively regenerate bone. This "smart hip" system has already been demonstrated successfully on animals.
A current prototype allows physicians to activate the "smart hip" via wireless Bluetooth and a computer. The network of actuators which help stimulate bone growth at the implant's surface has also undergone tests in cell studies as well as animals.
Buildings or commercial jetliners could soon get a protective coating of shatter-resistant armor similar to the material lining abalone shells. Finnish researchers have developed the lightweight reinforcement so that people can simply paint it on whatever structure, reports Technology Review.

After cardiac arrest, lowering someone’s body temperature can prevent life-threatening brain damage. It’s so critical that New York City requires ambulances to take some patients up to 20 minutes out of the way to hospitals with cooling equipment. EMTs could improve patients’ chances further using RhinoChill, a new portable nose spray that cools the brain on the scene.
A new super-fast book-scanning technology could make publishers cringe even more than when they heard about Google Book Search. A University of Tokyo researcher has developed a "book flipping scanning" method that does exactly what it sounds like, digitizing 200 pages per minute, according to IEEE Spectrum. The Japanese researchers hope to enable a digital library for Japanese manga comics.
The problem with surveillance cameras is that they can see but they can't think, which means there always has to be a human on the other end making cognitive sense of what's right in front of the camera. But if we meshed machine vision with visual intelligence, DARPA argues in a solicitation for its new "Mind's Eye" program, we could remove the human element from myriad tasks.
All those hybrid and electric cars, wind turbines and similar clean tech innovations may count for nothing if the U.S. cannot secure a supply of rare earth minerals. Ditto for other advanced telecommunications or defense technologies, scientists told a U.S. House subcommittee.
China has supplied 91 percent of U.S. consumption of rare earths between 2005 and 2008, and continues to represent the world's largest rare earth exporter. But the Chinese have warned that their own domestic industry appetite for rare earths may eventually force them to stop exporting -- an action that would leave the U.S. high-tech industries crippled without other readily available supplies.
Scientists have already created mini-cyborgs out of living cells and semiconductor materials, but now biological cells can also contain tiny silicon chips. Those silicon chips could become future intracellular sensors that monitor microscopic activities, deliver drugs to target cells or even repair cell structures, according to Nanowerk.
Skyborne chemical lasers have successfully shown off their potential killing power, and so the Air Force has now turned toward putting a more compact electric laser aboard its aircraft, Aviation Week'sAres Defense Blog reports.
One of the major problems with current cybersecurity measures is that while systems can detect the erratic behavior that heralds an incoming attack, there often isn't a whole lot those systems can do once the attack is underway short of pulling the servers offline, resulting in lost revenues and credibility for Web sites and a loss of key services for users. A new MIT system aims to change that by keeping servers and applications running even as it contains an incoming cyberattack.
