Levitation

Scientists at the University of St Andrews have used a lens to create a levitation effect. (Ignore the photo in the article, for some reason they illustrated it with a cheesy shot of a magnetic toy) The Casimir Effect is an attractive force between objects due to “resonance of all-pervasive energy fields in the intervening space between the objects”. What the physicists have done is found a way to make this field repel, rather than attract. This is mainly important to micro- and nano- technology, where the stickiness of the Casimir Effect is a pretty big hurdle.
