Physicists find ways to control gamma radiation

Researchers from Kazan Federal University, Texas A&M University and Institute of Applied Physics (Russian Academy of Sciences) found ways to direct high frequency gamma radiation by means of acoustics. Their paper describes an optical 'switch'—a device able to let through or stop gamma quanta by switching the acoustic field. Basically, the mechanism makes iron 'transparent' for gamma rays when needed.
