Invisibility cloaks and deflector shields, once a staple of popular science-fiction, are now the real deal, researchers say. Cloaking and shields have long protected starcruisers from blaster shots ...

One of the gravest dangers facing future astronauts traveling to Mars will be radiation in space: If the long trip doesn't kill them, cancer eventually could. These threats can, however, be defeated.

Radiation in space is one of the major obstacles to human exploration of the solar system. Astronauts on a round-trip to Mars could be exposed to radiation doses 66,000 times higher than on Earth. But ...

Physics students at the University of Leicester designed a concept for fully operational deflector shields, but there's one problem: they'd blind whoever they protect. Michelle Starr is CNET's science ...

A Star Trek style deflector shield that could protect deep-space astronauts, such as the much-discussed manned mission to Mars, from cancer-causing levels of radiation is in testing, researchers have ...

There’s something so profoundly cool about the command “Shields up.” It’s reminiscent of the moment a platoon of Spartan warriors falls into a phalanx: i.e. the time for fighting is nigh, get into ...

Magnetic “deflector shields” could one day guard astronauts against dangerous space radiation, if experiments now underway pay off. Exposure to energetic charged particles could put astronauts on ...
