Two new recipes tell how to make objects vanish.

Two prescriptions for an invisibility cloak have been unveiled by physicists in the United Kingdom and the United States. The researchers say that in principle the technologies needed for building these devices already exist. “Invisibility is visibly close,” says Ulf Leonhardt of the University of St Andrews in Scotland, one of the researchers behind the proposals.
