Scientists demonstrate how they have have created, a new invisibility technique that doesn’t just cloak an object but masks an entire event in this illustration.

Most people don’t have any problem making time disappear – but scientists have cracked a very hi-tech way of doing exactly that. Scientists have developed a ‘temporal cloaking’ device that can hide events from view.

 Sound waves moving from left to right flow past the object and reform on the other side with no distortion.

City dwellers, rest easy. Engineers have designed a material that redirects sounds and could be used in buildings to shield them from noises. The sound-shielding material, which, if actually made, would be the first acoustic cloaking device, could also be useful in hiding military ships and other vessels from sonar.
