Before a drug can be used to treat patients, it goes through several rounds of testing for efficacy and toxicity, which begin in animal models. Zebrafish, a tiny species of fish native to South Asia, are cheaper to maintain ...

Whether running away from a predator or to win an Olympic gold, how fast we run determines the final outcome. Locomotion is produced when limb muscles contract in a co-ordinated fashion. This, in turn, is caused by electrical ...

The zebrafish is a master of regeneration: If brain cells are lost due to injury or disease, it can simply reproduce them—contrary to humans, where this only happens in the fetal stage. However, the zebrafish is evolutionarily ...

In vertebrate muscles, there are slow and fast muscle fibers. Fast muscle fibers contract rapidly, but are prone to fatigue. Slow muscle fibers have the property of slow contraction, but resist fatigue. Vertebrates use fast ...
