Scientists look to decode secret of Usain Bolt's speed

                Scientists may soon find the secret behind the athletic prowess of Jamaican sprinter Usain Bolt, the fastest man on Earth, thanks to a new tool that allows them to analyse muscle proteins and observe the molecules at work in unprecedented details. Researchers from Germany’s Max Planck Institute of Molecular Physiology have further developed cryo-electron microscopy, a technique that can be used to explain the cause of muscle diseases and identify features that make the musculature of top athletes so efficient. A tissue sample from world-record-holder Bolt could enable researchers to discover why some people can run so much faster than others.
