Most of the volume of epithelial cell bodies containing nuclei are aligned as a monolayer on the apical (upper) side. They extend pillarlike cell processes in a basal (downward) direction. At the ...

A team of scientists has constructed a robot leg that, like its natural model, is very energy efficient. BirdBot benefits from a foot-leg coupling through a network of muscles and tendons that extends ...

Scientists have developed a robot with legs inspired by the structure and gait of birds, which allows them to use fewer motors and consume less energy than designs inspired by human legs. The next ...

Stuttgart/Irvine – If a Tyrannosaurus Rex living 66 million years ago featured a similar leg structure as an ostrich running in the savanna today, then we can assume bird legs stood the test of time – ...
