Cheetahs Faster than Ferraris

Using lightweight, solar-powered collars with GPS and intertial-measurement devices, scientists found surprising results of the movements of cheetahs in the wild where, instead of record top speeds, the animals displayed agility and acceleration greater than high-performance sports cars and energy absorption when stopping three times greater than polo horses.

Barefoot Running

Scientists have found that running barefoot produces a markedly different impact profile than running in shoes, using more of the whole leg to lessen impact and injury instead of a potentially damaging "heel-strike" of more than two to three times body weight.
