With a lot of ingenuity and a little luck, researchers monitored the heart rate of a blue whale in the wild. The measurement suggests that blue whale hearts are operating at extremes – and may limit the whale’s size.
Recordings of birds taking off and landing have revealed that conventional ideas about the role of lift and drag during flight might need revisiting. The work could influence the design of aerial robotics.
