Not Quite Invisible:

The NYT declares "Scientists Take a Step Toward Invisibility." Well, kinda. Some scientists have developed what could more accurately be described as a cloaking device in that it appears to deflect a given frequency of electromagnetic waves without generating distortions, shadows, etc. of the sort that could be detectable. In practical terms, as I understand the story, this could lead to a "cloaking" device that could make an object invisible to radar. Actual invisibility is still a long way off, however.
