During embryonic development, mechanical forces are essential for cellular rearrangements driving tissue morphogenesis. Here, we show that in the early zebrafish embryo, friction forces are generated ...

Physicists in the US have made a peculiar discovery about how a small object slides over a rapidly rotating lubricated disk. They have found that if the object is tilted so that it only touches the ...

Friction is a force that resists the motion of one object against another. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. Scientists began ...

Irregularities present on a surface are often described as surface roughness or texture. These surface textures such as grooves and dimples impart friction, which is the force between two sliding ...

It’s a moonless night. The wind howls outside. A door opens slowly, as if pushed by an invisible hand. “Cre-e-e-a-k.” That sound — a horror movie cliché — is the result of friction. A stealthier ...
