JILA researchers have developed a laser-based source of terahertz radiation that is unusually efficient and less prone to damage than similar systems. The technology might be useful in applications such as detecting trace gases or imaging weapons in security screening. JILA is a joint institute of the National Institute of Standards and Technology (NIST) and the University of Colorado at Boulder. Terahertz radiation"”which falls between the radio and optical bands of the electromagnetic...

University of Maryland researchers propose method to sniff out dirty bombs via the electromagnetic breakdown of air Researchers at the University of Maryland have proposed a scheme for detecting a concealed source of radioactive material without searching containers one by one. Detection of radioactive material concealed in shipping containers is important in the early prevention of "dirty" bomb construction. The concept, described in the Journal of Applied Physics, is based on the gamma-ray...

It turns out the Herschel Space Observatory has a trick up its sleeve. The telescope, a European Space Agency mission with important NASA contributions, has proven to be excellent at finding magnified, faraway galaxies. Like little kids probing patches of dirt for insects, astronomers can use these new cosmic magnifying lenses to study galaxies that are hidden in dust. "I was surprised to learn that Herschel is so good at finding these cosmic lenses," said Asantha Cooray of the University of...
