Nano antenna concentrates light: Intensity increases 1,000-fold

(PhysOrg.com) -- Everybody who's ever used a TV, radio or cell phone knows what an antenna does: It captures the aerial signals that make those devices practical. A lab at Rice University has built an antenna that captures ...

Process for the optical analysis of trace gases optimized

Laser-based absorption spectroscopy is an important method for determining the concentration of gas components in a sample. Modern devices are highly specialized for detecting very specific gases, such as trace gases in the ...

Scientists measure the distance to stars by their music

A team of astronomers has used asteroseismology, or the study of stellar oscillations, to accurately measure the distance of stars from the Earth. Their research examined thousands of stars and checked the measurements taken ...
