Contributions of Limb Joints to Energy Absorption during Landing in Cats

Contributions of Limb Joints to Energy Absorption during Landing in Cats SUMMARY: How is it that cats are able to jump down from high places and not hurt themselves? Researchers in this study observed 5 cats, jumping from various heights, for clues as to what sorts of forces and shock absorbers were at work. The… Continue reading Contributions of Limb Joints to Energy Absorption during Landing in Cats

Planarian Fission

Mechanics dictate where and how freshwater planarians fission SUMMARY: Planarians are tiny squishy worms that go through binary fission by ripping themselves in two parts: the head part and the tail part. This article looks at the mechanism of the ripping. First, there is the formation of the waist, then pulsation of the head, then… Continue reading Planarian Fission
