Mitochondria may sustain temperatures more than 10 °C warmer than human cells, say researchers. 

Researchers confirm the unprecedented endothermic abilities of a South American reptile.

Researchers develop a method for estimating the body temperatures of long-extinct species, and suggest that dinosaurs operated somewhere between endothermy and exothermy.

The opah, or moonfish, is a deep-sea fish that regulates its body temperature more like a mammal than any of its finned kin, researchers have determined.

The leading argument for dinosaurs being cold-blooded is overturned as a nearly identical bone structure is found in mammals.

Evidence that large dinosaurs had body temperatures similar to modern-day mammals suggests they were either endothermic or extremely good at conserving body heat.
