Israeli scientists freeze water by warming it.

ccktech (714574) writes "As reported by NPR and Chemistry world this morning the Journal Science has a paper by David Ehre, Etay Lavert, Meir Lahav, and Igor Lubomirsky of Israel's Weizmann Institute has figured out a way to freeze pure water by warming it up. The trick is that pure water has different freezing points depending on the electrical charge of the surface it resides on. They found out that a negatively charged surface causes water to freeze at a lower temperature than a postively charged surface, Putting water on the pyroelectric material Lithium Tantalate which has a negative charge when cooler but a positive change when warmer; water would remain a liquid down to 17 degrees C. and then freeze when the substrate and water was warmed up and the charge change positive where water freezes at 7 degrees C."

I have gone through all the links and could not find any reference to freezing water by warming it in any of them. Have I missed something? or have the submitter misinterpreted?
