Tractor beam progress...

Scientists have created a tractor beam that can drag objects for distances of up to 20cm - around 100 times further than in previous experiments.

The doughnut-shaped laser is also reversible - so it can either repel or attract objects.

In future, these beams could be used to study atmospheric pollutants, or to retrieve delicate particles of material for examination.

Sounds like it'd burn your skin off before pulling you any closer.
