Chapter 1459 - Chapter 1024 Suspect_2

There have been numerous reports on this aspect, one report pointed out: at the end of the 20th century, American chemist Malcolm Henry discovered the secret of why polar bears are not afraid of the cold. Henry observed the fur of polar bears using an electron microscope and found that the hairs are colorless, transparent, hollow tubes, essentially tiny "photoelectric tubes" through which only ultraviolet light can pass. Polar bears use these photoelectric tubes to absorb ultraviolet rays from the sunlight, thereby increasing the temperature around their bodies. Additionally, their several centimeters thick subcutaneous fat layer and water-resistant fur provide excellent insulation. Thus, clad in a self-regulating fur coat, polar bears can traverse the icy realms without fear of the cold!
