Bacteria Beats Sudoku; NY Times Crossword Beware

A team of scientists from the University of Tokyo which competed in the International Genetically Engineered Machine competition created the problem-solving bacteria. It consisted of a group of 16 types of E. coli that were genetically identified by their placement on a four by four grid. In place of numbers the team used 4 colors to represent values, and each strain of bacteria was able to express one of the four. A few squares were given color at the start to simulate typical sudoku play.
