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.
Sony’s advance in image sensors appears quite natural: the company has developed a set of curved CMOS image sensors based on the curvature of the eye. A report on the sensors in IEEE Spectrum said that, ‘in a bit of biomimicry,’ Sony engineers were able to achieve a set of curved CMOS image sensors …
A team of researchers at the Cedars-Sinai Heart Institute in Los Angeles have managed to transform regular heart cells in pigs into pacemaker cells; cells that naturally keep the heart’s rhythm in step. Researchers hope this breakthrough will lead to biological pacemakers, potentially saving many lives.
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:
