The London Olympics are about to begin,and spectator will again be revited by feats 1 that would've been imposibily when the modern Olympics began in 1986. Jaw-dropping records are attainable 2 in part because of advances in material science. New materials have led to equipment like super light and strong _ pools and bathing suits that improve the flow of body and water. Such developments are detailed 3 in a series of articles and the journal nature materials.The scientists say other advances are _ that build sensors 4 into athletes's clothing for, for instance, measuring performance and training or protective gear that repairs itself when damaged and advances in science can help Olympians internally as well.Elite 5 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 bridge the break, so scientists are humming in on the best combinations of bio-compactble materials along with growth factors and other compounds as well as implanted cells and proteins to help mend what would have been until now nearly untreatable injuries, so that world-class athletes can push the limits of sports and science.
