American biologists stated that only half of the muscle strength appears in the longitudinal cuts and the other half are various changes in the shape axis. These findings cast serious doubt most modern theories on the work of the muscles.
David Williams, together with his colleagues, he built a three-dimensional model of the heart muscle, which took into account the structure of the heart, and how the filaments of myosin and actin in its cells. During contractions virtual muscles scientists have examined changes in its geometry, as well as what contribution in increasing her strength made the various components of the muscle.
Despite the fact that the model was very accurate, as it described in detail the relationship of the strength of the muscles and their abbreviations, scientists have identified a number of significant gaps. For example, the lion's share of muscular strength depends on uniform changes in their grid, composed of protein filaments that are not along the axes of abbreviations and extended in other directions. After scientists "deleted" data chain from the virtual model, the strength of the heart muscle has been halved.
Finding this important phenomenon, a group of scientists led by David Williams, decided to find him in nature. To achieve this goal, studies have been carried out several butterflies, whose structure and operation are similar to human cardiac muscle. From the butterfly wings were removed, the muscles, and then using a current was induced contraction. Scientists were able to study thoroughly the structure of muscle by x-ray crystallography. In the end, this whole experiment confirmed the results obtained during simulation. It is tempting to think that it is necessary to revise many of my ideas about the work of the muscles.
