Tractor Beam

Scientists have invented a tractor beam. Working on new medical technology scientists in Scotland, working with scientists in the Czech Republic, have discovered a way to attract particles with a light source. Generally light pushes objects away from it,  however,

"The method relies on negative radiation pressure and can actually have practical uses in fields like medicine, where cells would be possible to sort based on material by pulling them aside into groups."
