If I understand the article correctly, they found a phase transition reaction, a chemical reaction that occurs in liquid water below 0 C that splits the body of liquid water into one continuous region of high density and one of low, so its no longer a uniform liquid.
This would also release heat, like the freezing reaction (and unlike random rearrangements of molecules in the liquid).
