We recently saw research that suggested negative radiation pressure in light could lead to a practical tractor beam. A partnership between the Czech Republic's Institute of Scientific Instruments and Scotland's University of St. Andrews can show that...

Developing a real, working tractor beam has regularly been an exercise in frustration: it often relies on brute force attempts to induce a magnetic link or an air pressure gap, either of which falls a bit short of science fiction-level elegance. The ...
