This morning, Guardian reporter Alexandra Topping covers a record-breaking computer solution to Rubik's Cube:
It is the holy grail for puzzle-lovers around the world. A task that has thwarted the greatest minds for generations. But the ultimate solution to the Rubik's cube may be within grasp.
A supercomputer has been working without pause to provide conclusive evidence that the cube can be returned to its original state in no more than 26 moves.
The computer took 63 hours to provide the proof, which goes one better than the previous best solution.
The computer worked 63 hours without pause? It didn't even take a Minesweeper break?
Apparently they've proved it to 23 or less moves now! According to Wikipedia, anyway... Check out the article (at the very bottom) if you're interested.
