WASHINGTON (AP) -- Harry Potter would be pleased, science is slowly catching up with him.
Scientists have taken a small but important new step toward making a cloak of invisibility.
Researchers in Germany say they were able to cloak a tiny bump in a layer of gold. It prevented its detection at nearly visible infrared frequencies.
The device worked in three dimensions, while previously developed cloaks worked in two dimensions.
In a report in today's online edition of the journal Science, researchers say the cloak is made of crystals with air spaces in between, sort of like a woodpile, that bends light, hiding the bump.
