One of them is more troubling than the other
Researchers have discovered that although bowhead whales live long lives, the bulls have small testicles and one gene is likely responsible.
The decline in Arctic sea ice only made it to 10th place on the list in what should have been a warm summer in 2022, but the downward trend remains.
