What do a bat, a jellyfish and a humpback whale have in common? For one thing, these animals use their natural propulsors, such as wings, bells and flukes, to move through their environment, be it air or water. Last week a group of researchers published a study in Nature Communications that indicates that these and many other animals from distantly related groups seem to have attended the same school of propulsion. And one of the subjects they studied there was all about being flexible.
They may be found in swarms of marvelous colours, or floating solitary like transparent pieces of blown glass. From waters East to West, and North to South the jellyfish knows Continue reading

In terms of speed, the great cat faces little competition. Nevertheless, today, no legged robot is speedier than Darpas’s new Cheetah bot which can run 30 km/hr in cheetah-like fashion.
