Engineers designed modular, spring-like devices to maximize the work of live muscle fibers so they can be harnessed to power biohybrid robots. Our muscles are nature's perfect actuators -- devices ...

Skeletal muscle mechanics and force generation are governed by complex interactions between contractile proteins and passive structural elements. At the cellular level, the sarcomere – the fundamental ...

The latest viral clip of a faceless android twitching under its own power has pushed humanoid robotics into a new, unsettling ...

Researchers have investigated the effect of increased cell temperature on the contractility of skeletal muscle and cardiac muscle by heating the muscle proteins using advanced microscopical techniques ...

In a recent study published in Nature Communications, researchers investigate the pathophysiology of post-exertional malaise (PEM) in long coronavirus disease 2019 (COVID-19) patients, focusing on ...

In a recent study published in Reviews in Medical Virology, researchers reviewed the mechanisms of muscle tissue injury, aggravating conditions, and associated sequelae in long coronavirus disease ...

You're relaxing on the sofa when suddenly your eyelid starts twitching. Or perhaps it's a muscle in your arm, your leg, or ...

Infectious agents can cause muscle twitching and spasms, too. The most commonly known is probably tetanus, which causes a phenomenon called lockjaw, where the neck and jaw muscles contract to the ...

Much like their name implies, the quadricep muscles were once thought to be a set of four muscles, with the name “quad” translating to “four or fourth” in Latin. However, it has since been discovered ...

Previous studies have shown that, in obesity, deposition of lipid droplets in skeletal muscles and changes of muscle fiber types can both contribute to insulin resistance. However, the relationship ...
