New scientific concept for a Star Wars-like tractor beam

Physicists from ITMO University have developed a model of an optical tractor beam to capture particles based on new artificial materials. Such a beam is capable of moving particles or cells towards the radiation source. The ...

How to 3-D print your own sonic tractor beam

Last year Asier Marzo, then a doctoral student at the Public University of Navarre, helped develop the first single-sided acoustic tractor beam—that is, the first realization of trapping and pulling an object using sound ...

Optical tractor beam traps bacteria

Until recently, if scientists wanted to study blood cells, algae, or bacteria under the microscope, they had to mount these cells on a substrate such as a glass slide. Physicists at Bielefeld and Frankfurt Universities have ...

Sonic tractor beam invented (w/ Video)

A team of researchers from the Universities of Bristol and Sussex in collaboration with Ultrahaptics have built the world's first sonic tractor beam that can lift and move objects using sound waves.

Scientists demonstrate Stokes drift principle

In nature, waves – such as those in the ocean – begin as local oscillations in the water that spread out, ripple fashion, from their point of origin. But fans of Star Trek will recall a different sort of wave pattern: ...
