The London Olympics are about to begin, and spectators will again be riveted 1 by feats 2 that would have been impossible when the modern Olympics began in 1894.
Jaw-dropping records are attainable 3 in part because of the advances in materials science. New materials have led to equipment like super light and strong vaulting 4 poles and bathing suits that improve the flow of bodies and water. Such developments are detailed 5 in a series of articles in the journal Nature Materials.
The scientists say other advances are afoot that build sensors 6 into athletes' clothing for, for instance, measuring performance and training or protective gear that repairs itself when damaged. And advances in materials science can help Olympians internally as well. Elite 7 athletes may tear cartilage or break bones, but cartilage doesn't have enough blood and cells to mend well. And sometimes bones just can't naturally abridge 8 the break.
So scientists are homing in on the best combinations of bio-compatible materials, along with growth factors and other compounds as well as implanted cells and proteins to help mend what have been until now nearly intractable injuries. So that world-class athletes can push the limits of sports and science.
