A carbon-nanotube-infused ink for ink-jet printers first developed in the Rice Univ. lab of James Tour has been used to make thin-film transistors in radio-frequency identification tags that can be printed on paper or plastic. The transmitter can be invisibly embedded in packaging, instantly sharing far more information than a bar code.

The Optical Society of America has highlighted an upcoming presentation at an annual optics conference San Diego in which the researchers from Germany will describe a method for encoding a wireless broadband signal through the light generated by a common household lamp. Visible-frequency signals have a tremendous advantage in bandwidth, and modulation would be so fast no one would notice the flickering.

Built by university students in Missouri, the tractor-tread-equipped robot relies on an infrared camera and LIDAR technology to relay photographs of tight interior spaces like buildings or caves. Suitable for hunting terrorists or structural damage, the robots weighs about 200 pounds and costs $25,000. Future versions will likely get lighter and smaller.

For consumers, wireless technology is great. But if you’re running a nuclear power plant or a pharma production line, the risk of failure is too great. Idaho Lab’s new wireless sensor network will track down the weaknesses of these systems by simulating industrial settings in a physical lab environment. They hope to supply standards the industry now lacks.

Among the most astonishing revelations made by humans about the natural world was Isaac Newton’s epiphany about the apple and its unwavering tendency to fall toward the center of the earth. The rare manuscript of this story, as told by Newton to William Stukeley, is now online for the first time.

Connectedness is not a luxury—it’s a tool for survival because it stimulates response. Haitians and their loved ones see the direct benefits in efforts by Google to provide up-to-minute news on the whereabouts of individuals. And, more indirectly, the rapid giving model is accelerating philanthropy in ravaged lands.

The Georgia Tech team did not win the DARPA Network Challenge—MIT found the 10 balloons in under nine hours—but they came close, finding nine balloons and along the way learning about the benefits and pitfalls of networked groups. Their charity pledge won fans and cooperation, but opponents infiltrated their network, giving false information.
