In this video, we uncover the fascinating world of mechanical advantage through three simple yet powerful machines , levers, pulleys, and gears. For centuries, humans have used these inventions to ...

Gears are ubiquitous in the man-made world, found in items ranging from wristwatches to car engines, but it seems that nature invented them first. A species of plant-hopping insect, Issus ...

It was a mechanical marvel, so advanced that it baffled archaeologists and scientists for over a century. A device that would ...

A Living Machine This complex arrangement of rods and interlocking gears is the hip joint of an immature planthopper insect. It’s the only instance of functioning, interlocking gears that has been ...

Temperature-controlled, reversible shifting of molecular gear motion in a solid crystal opens new possibilities for material design.

The clutch stack arrangement of the triaryltriazine molecules enabled adjacent molecules to hook on to each other as the phenylene rings rotated, much like interlocking gears.

A separate sketch shows a row of four directly interlocking cogs, while others look to describe gears within different rigid elements.

Known as “the world’s first computer,” the damaged object was once a bronze box that measured about a foot tall and featured a system of interlocking gears.

The two interlocking gears on the insect's hind legs help synchronize the legs when the animal jumps.

Gears are ubiquitous in the man-made world, found in items ranging from wristwatches to car engines, but it seems that nature invented them first.
