Researchers have just made the unexpected discovery of a novel organization of muscle fibers in Parophidion vassali, a fish that lives in the Mediterranean Sea and, like many fish, uses specialized ...

Figure 1: Acute sarcolemmal disruption in clustered myocytes of BIO 14.6 hamster skeletal muscle after forceful contraction. We calculated the percentage of all muscle fibers taking up procion orange ...

The contraction kinetics of calcium-activated skinned muscle fibers were studied after step decreases in load by means of a quickly responding recording system. The steady velocity at a given relative ...

Beet juice boosts endurance for many (but not all) people, according to a series of studies over the past five years or so. The active ingredient appears to be nitrate, which somehow reduces the ...

Action potentials, with no accompanying contraction, were recorded from muscle fibers in which the transverse tubular system had been disrupted. The results show that action potentials require an ...

In two new studies, North Carolina State University researchers designed and tested a series of textile fibers that can change shape and generate force like a muscle. In the first study, the ...

Artificial muscles made from twisted fibers could offer a compact and lightweight alternative to conventional motors in applications such as miniature robots or medical implants. But these synthetic ...

No matter how regularly you exercise, artificial muscles have long since surpassed their natural counterparts. Now, researchers from the Department of Mechanical Science and Engineering at the ...

The first view of the physical mechanism of how a blood clot contracts at the level of individual platelets is giving researchers a new look at a natural process that is part of blood clotting. The ...

A new study out of Edith Cowan University in Perth, Australia, suggests that a few seconds of focused muscle training each day might be enough to increase strength — a surprising finding that could ...

Researchers at the University of Liège, Eric Parmentier and Marc Thiry have just made the unexpected discovery of a novel organisation of muscle fibres in Parophidion vassali, a fish that lives in the ...
