Scientists at Brigham Young University have found a way to create amazing 3D holograms in mid-air by using lasers and a tractor beam that manipulates near-invisible particles in the air.

A water-based tractor beam that could contain oil spills and manipulate floating objects cannot yet be explained by mathematical theory. Michelle Starr is CNET's science editor, and she hopes to ...

However, researchers at the Australian National University have developed a "tractor beam" (really, a wave generator) that would make it trivial for you to float anything to its intended destination.

Physicists have created a tractor beam on water, providing a radical new technique that could confine oil spills, manipulate floating objects or explain rips at the beach.

Instead, it's a group of wave generators that -- more or less -- ends up manipulating ocean-bound objects in a similar fashion. The tractor beam is unencumbered by the movements of the ocean, ...

So anyway, those tractor beams. ... Small waves behave as expected: the surface fluid moves away from the wave generator, in the way that’s familiar to surfers and sailors.

A team of scientists have brought Sci-fi dreams to life by creating the world's cheapest tractor beam - out of spare parts worth less than £70. And even better, they've released a step-by-step ...

A tractor beam which can push and pull particles could be scaled up and used to control the flow of air pollution. Monday 20 October 2014 08:55, UK.

That’s a far cry from previous tractor beam technologies, which required phased arrays of more than 50 sound channels, with each made up of a signal generator and an amplifier.

Scientists may have discovered how to create a real-life tractor beam using electromagnetic radiation that can draw particles toward it. The result is something very … The post Scientists might ...

Imagine a tool capable of moving cells and microparticles without physical contact, utilizing only light. It’s like a sci-fi tractor beam, except it’s much more precise and operates at a much ...

And as opposite charged attract, the tractor beam can begin its towing work. The team estimates that it could pull a several-ton satellite around 200 miles over two to three months—not fast, but ...
