Visual motion is an important source of information for separating objects from their backgrounds. A spider camouflaged against a branch, for instance, immediately loses its invisibility once it ...

Researchers have discovered a new method to move objects using ultrasound waves, opening the door for using contactless manipulation in industries such as robotics and manufacturing. University of ...

Researchers have developed a technique to move objects around with a jet of wind. The new approach makes it possible to manipulate objects at a distance and could be integrated into robots to give ...

For the first time, physicists have simulated what objects moving near the speed of light would look like — an optical illusion called the Terrell-Penrose effect. When you purchase through links on ...

Using ultra-fast laser pulses and special cameras, scientists have simulated an optical illusion that appears to defy Einstein's theory of special relativity. One consequence of special relativity is ...
