Tech and Science Post: Protein study reveals how the tiny shrew achieves a resting heart rate of 1,020 beats per minute

The shrew’s resting heart rate can reach up to 17 beats per second, equivalent to about 1,020 beats per minute. In comparison, the average human resting heart rate is around 60 to 100 beats per minute, making the shrew’s resting heart rate approximately 10–17 times higher than that of humans.

Until now, it has been a mystery how these small mammals achieve such an extreme resting heart rate, but a new study, just published in the journal Science, sheds light on the mystery.
