There’s a discrepancy in the animal kingdom. While many key traits such as strength, limb length, lifespan and brain size tend to increase with animals’ size, maximum running speeds tend to be ...

A new study has answered a long-held question about why medium-sized land animals like cheetahs tend to be fastest. There's a discrepancy in the animal kingdom. While many key traits such as strength, ...

Coordinating dozens of muscles typically requires complex neural control, and it is unclear how much of that coordination must come from the brain versus the body’s structure. Professor Mitra Hartmann ...

In a serendipitous discovery, UC San Diego researchers using cryo-EM technology captured the first visualizations of the 3-D structure of the muscle acetylcholine receptor in fetal and adult muscles.
