Scientists have created the first device to render an object invisible in three dimensions.
The "cloak", described in the journal Science, hid an object from detection using light of wavelengths close to those that are visible to humans.
Previous devices have been able to hide objects from light travelling in only one direction; viewed from any other angle, the object would remain visible.
This is a very early but significant step towards true invisibility cloaks.
