Spider silk as mechanical lifeline
Article Abstract:
A clear relationship exists between the mechanical properties of silk drag-lines of the spider and its weight. Drag-lines secreted from the body of the spider are a tool for it to move. The elastic-limit strength of drag-lines increases linearly with increasing spider weight. It is safe for a spider to use a single drag-line to carry its weight and a prey item, as long as the total stress remains less than twice its weight. A stress equivalent to that produced by about six times the spider's weight can break the drag line.

Low mechanical signals strengthen long bones
Article Abstract:
High frequency, very-low-magnitude vibrations have been found to strengthen the bones of sheep. This research may be useful for treating osteoporosis and other skeletal problems.

Effects of mechanical forces on maintenance and adaptation of form in trabecular bone
Article Abstract:
A computational model of the metabolic process in bone is presented. This model confirms that cell coupling is controlled by feedback from mechanical load transfer.
