Researchers at the Norwegian University of Science and Technology (NTNU) have patented and are commercializing GaAs nanowires grown on graphene, a hybrid material with competitive properties. Semiconductors grown on graphene are expected to become the basis for new types of device systems, and could fundamentally change the semiconductor industry. The technology underpinning their approach has recently been described in a publication in the American research journal Nano Letters.

To celebrate the puzzle’s 40th anniversary, today’s Google Doodle is a fully-functional Rubik’s Cube! If you had a cube for every possible arrangement of the 54 colored squares, and you laid them end-to-end, those 43,252,003,274,489,856,000 cubes would extend 261 light years.
But no single Rubik’s cube can be configured to all of those Rubik’s universes.
If the traditional cube isn’t challenging enough for you, you can head over to the Chrome Cube Lab and try your digital hand at some other cubic puzzles.
The folks at Numberphile took an in-depth look at the math behind a Rubik’s Cube in a series of videos on YouTube. Here’s one of them:
