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. Read more.
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.
The Humans in Space Art Program and NASA’s International Space
Station Program are teaming together to invite college students and
early career professionals to take a journey with us. Through the
international Humans in Space Art Challenge, we invite you to explore “How will space, science, and technology benefit humanity?”
and to express your answer creatively in a video 3 minutes long or
less. Video artwork can be of any style, featuring original animation,
sketches, music, live action drama, poetry, dance, Rube Goldberg
machines, apps, etc. Read more.

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.
The Space is Business competition is organized by the Space Generation Advisory Council (SGAC) in cooperation with the International Astronautical Federation (IAF).
