Hope springs eternal for die-hard Star Trek fans that scientists will one day build an actual, working antimatter propulsion engine similar to the one that powers the fictional starship Enterprise.

New Material for Advanced Metamaterials

Metamaterials are a curious class of materials with highly engineered structures, so as to have unusual characteristics. In the case of optical metamaterials, light can be made to bend backwards, which opens the door to invisibility cloaks and super lenses. Making metamaterials is not easy though, not only because of...
