Wire Guides Terahertz Waves Among the challenges to making terahertz sensing and imaging applications more practical is finding ways to direct the waves to specific targets. Researchers have now shown that a piece of stainless steel wire 9/10ths of a millimeter in diameter causes terahertz waves to propagate in the space around wire. |

Infrared headset nixes radiation Many cell-phone users have taken to using hands-free headsets to avoid the microwave radiation the devices emit, but the electrical wires that connect the headsets to the phones can also act as antennas for microwaves. A headset that connects via infrared light sidesteps the radiation problem. |

Picosecond 'kettle' to probe chemical reactions A way to boil water in less than a trillionth of a second has been devised by researchers. The approach, which is still theoretical, uses a concentrated pulse of terahertz radiation to raise the temperature of a small sample of water by around 600 C. |
