Birds may stay warm with the help of red blood cells
Researchers at Lund University in Sweden were interested in understanding how birds adapted to cold weather. Birds can’t turn up the heat in their birdhouse, so it is important for them to find physiological ways to stay warm. While they can store body fat and grow more feathers for insulation, metabolism is the primary way endothermic animals create body heat. Mitochondria produce cellular energy (ATP) but can also create heat […]
