Manipulation of particles whose sizes are a billionth of a metre poses a huge challenge and is a vast area of research. Manipulation of objects on this scale has important application from medicines to quantum technologies. Scientists from the Indian Institute of Science, Bangalore have devised a new approach to trap and maneuver nanoscale objects. 

A new behaviour in crystals discovered

Over the last few centuries, we have gained a decent understanding of nature. However, every now and then, nature plays a surprising new card to stun and intrigue. One such new observation has led to the discovery of a new behaviour operating in crystalline materials.
