This is creation - plants and all things define binary information in their structure. We destroy it by burning the structure for example, and this creates heat. Its a bidirectional process - the physical definition of any information involves capture of free molecules or atoms of some kind, and those things not captured have energy and movement which we see as heat. Capture them to a static structure, and the number of free agents is reduced, therefore the heat is reduced. The minimum energy of any agent that can be captured into a structure like this is 0.69 kT, this is the point of the article, though the researchers appear to have been more interested in converting informatiion to heat (Destruction), what is far more valuable, is the conversion of heat energy to structure, because this is creation, and it cools by definition.
