As you bite into a crisp apple, your jaw muscle contracts, allowing you to grind the fruit between your teeth. When you climb a flight of stairs, your gluteus maximus (or "glutes") push your body ...

Despite centuries of study, scientists are still finding new details and even overlooked structures within the human body. As researchers explore anatomical differences between individuals, it’s ...

Muscle-on-chip systems are three-dimensional human muscle cell bundles cultured on collagen scaffolds. A Stanford University research team sent some of these systems to the International Space Station ...

Wait for initial healing: Instead of treating the wound right away, Muneoka and his team waited for the skin to close up and ...

Cellular heterogeneity is an inherent feature of all biological systems, allowing for cellular specialization to meet the diverse demands imposed upon tissues and cells 1. The classic view of skeletal ...

Skeletal muscle aging is a key contributor to age-related frailty and sarcopenia with substantial implications for global health. Here we profiled 90,902 single cells and 92,259 single nuclei from 17 ...

In a world with rapidly aging societies, there's a need for a detailed understanding of the cause and progression of diseases associated with aging. Skeletal muscle is the key motor system in the ...

A biohybrid hand which can move objects and do a scissor gesture has been created. The researchers used thin strings of lab-grown muscle tissue bundled into sushilike rolls to give the fingers enough ...

Engineers at MIT have devised an ingenious new way to produce artificial muscles for soft robots that can flex in more than one direction, similar to the complex muscles in the human body. The team ...
