Spider-Man-style robotic graspers defy gravity

Specially designed vacuum suction units allow humans to climb walls. Scientists have developed a suction unit that can be used on rough surfaces, no matter how textured, and that has applications in the development of climbing ...

Molecules move faster on a rough terrain

Roughness, the presence of irregularities on a surface, is commonly associated with slower motion and stickiness. This is true at different length scales: at human size (1 meter), it takes longer to walk along a path that ...

Nanostructures help to reduce the adhesion of bacteria

Scientists have shown how bacteria adhere to rough surfaces at the microscopic level. Now a team of researchers has discovered that precise analysis of the topographical composition of nanostructured surfaces provides a direct ...

The secret to sneaky float serves

A research team led by the University of Tsukuba studied the aerodynamics of a volleyball using a wind tunnel and hitting robot. They found that no matter the orientation of a standard ball, the pattern of panels presents ...
