Physicists have built a tractor beam out of lasers that can both repel and attract objects across distances 100 times farther than previously possible. Michelle Starr is CNET's science editor, and she ...

Lightning strikes are a major trigger for wildfires, including the record-breaking blazes that devastated Australia, California and other regions this year. An international research team has now ...

Scientists are working on bringing a tractor beam from science fiction to reality. The researchers are planning to use beams of electrons to create opposite charges and attract object to the beam for ...

A team of engineers is working on a real life “tractor beam,” a staple device of spacefaring sci-fi that can push and pull objects at a distance without making contact. Tantalizingly, their early ...

Scientists have built a real-life tractor beam that can pull actual objects using nothing but light. But it has one big drawback: it’s absolutely tiny. Despite its still tiny size, the new tractor ...

The newly devised ‘tractor beams’ are not like the sort envisioned in Star Trek for grabbing spaceships; these tractor beams are deployed for trapping and manipulating objects one billion times ...

Have scientists created a real-life prototype of a tractor beam, that glowing shaft of green light that the folks on the Starship Enterprise use to seize hold of enemy vessels? I'm a sucker for any ...
