Quantum physics enables revolutionary imaging method

A new quantum imaging technique generates images with photons that have never touched to object -- in this case a sketch of a cat. This alludes to the famous Schrödinger cat paradox, in which a cat inside a closed box is said to be simultaneously dead and alive as long there is no information outside the box to rule out one option over the other. Similarly, the new imaging technique relies on a lack of information regarding where the photons are created and which path they take.

  Researchers from the Institute for Quantum Optics and Quantum Information (IQOQI), the Vienna Center for Quantum Science and Technology (VCQ), and the University of Vienna have developed a fundamentally new quantum imaging technique with strikingly counterintuitive features. For the first time, an image has been obtained without ever detecting the light that was used to illuminate the imaged object, while the light revealing the image never touches the imaged object.

Solar Power, Origami-Style

Researchers say origami could be useful one day in utilizing space solar power for Earth-based purposes. Imagine an orbiting power plant that wirelessly beams power down to Earth using microwaves. Sending the solar arrays up to space would be easy, Trease said, because they could all be folded and packed into a single rocket launch, with "no astronaut assembly required." Read more.

Print your own psychedelicious sugar cubes

Liz von Hasseln and her husband Kyle decided to bake a birthday cake for a friend in 2011. They didn't own an oven, but being graduates of the Southern California Institute of Architecture, they did own a 3D printer. After a few weeks experimenting with different sugars and an inkjet printer, they printed a tiny cupcake topper with their friend's name in cursive sugar. "When we graduated, we launched The Sugar Lab," says Liz. The startup has recently been acquired by Los Angeles additive firm 3D Systems. Its big project: developing a commercial food printer, the Chef Jet, for pâtisseries to use. Read more.
