Just published and quite detailed. The Hittites in the OT appear to be the group moving southeast into what today would be southern Syria, and intruding into northern Israel.
The Hittite Empire in today's Turkey, doesn't get much press, but was a major player in the Eastern Mediteranean (Egypt, Ugarit, Cyprus) and east against what would be Mari and early Assyria.
The Nature article discusses the Hittite economy, dependence on agriculture, and collapse, suggested by 3 years of intense drought. The issue, of course, is the similar collapse of a whole sequence of empires near the same time (end of the Late Bronze).
And if you enjoy tree-ring dating, they're using a juniper species as a base ... ours are pretty iffy for climate/years.
