Created by a laser beam able to attract and repel objects

Researchers from the Australian national University has demonstrated some of the capabilities of remote moving objects "force rays". The past experience, the subject moved through the water, however, scientists have gone even further and created a laser beam, able to move things from yourself and to yourself.

The method consists in using so-called optical vortex, which is the source of the appearance of the photophoretic force, pushing the particles to the darker region of the laser beam, according to the resource Gizmag. Thus, with a laser you can change the direction of movement of the subject.

According to the developers, their new method can find wide application in the real world. Attracting the laser beam can be used to manipulate the waste or by sampling atmospheric pollution.

Unfortunately, at the moment, the researchers were able to move an object the size of a fifth of a millimeter at a distance of 20 centimeters. And although at first glance it does not seem so outstanding, in any case attracts the laser beam is a huge step in the development of this technology.

In the near future, researchers will seek to develop the technology to such an extent that the laser beam could manipulate larger objects in the far distance.
