The radiation is actually a series of short electromagnetic pulses pinging the cells at terahertz frequencies (which have wavelengths of about 0.1 millimeter, lying between microwaves and infrared light, according to the scientists' press release). Most of the recent T-ray experiments have dealt with quick, precise inspections of organic and mechanical material. Aside from quickly scanning you for contraband and awkward bulges at airports, other proposals have involved using terahertz radiation to look into broken microchip innards, peer into fragile texts and even comb airport luggage for bombs.

But similar to those hypothetical applications, you won't see T-rays in your PCs any time soon. The scientists have successfully demonstrated the concept on a weak ferromagnet, thulium orthoferrite (TmFeO₃), and even found that the terahertz radiation's effect was ten times greater than a traditional external magnetic field, meaning the new method is both far faster and more efficient. But the scientists have yet to publish tests on actual computer memory cells, so it's unknown when, or if, T-rays will buzz around inside your machine.
