Scientists identify origin of hiss in upper atmosphere Mar 6, 2008
"Here, we show that a different wave type, called chorus, can propagate into the plasmasphere from tens of thousands of kilometers away and evolve into hiss.

Scientists using laser light to detect potential diseases via breath samples, says new study Feb 19, 2008
Each comb line, or "tooth," is tuned to a distinct frequency of a particular molecule's vibration or rotation, and the entire comb covers a broad spectral range -- much like a rainbow of colors -- that can identify thousands of different molecules. Laser light can detect and distinguish specific molecules because different molecules vibrate and rotate at certain distinct resonant frequencies that depend on their composition and structure, he said.

Optimal band imaging with endoscopy facilitates the diagnosis of depressed-type early gastric cancer Feb 19, 2008
In contrast to narrow band imaging, in which the bandwidth of spectral transmittance is narrowed by optical filters, the OBI system is based on a new spectral estimation technique that replaces the need for optical filters. OBI takes an ordinary endoscopic image from the video processor and arithmetically processes the reflected photons to reconstitute virtual images for a choice of different wavelengths. (EurekAlert!)
Laser light may be able to detect diseases on the breath Feb 18, 2008
The remarkable combination of a broad spectral coverage of the entire comb and a sharp spectral resolution of individual comb lines allows them to sensitively identify many different molecules, as they show in their paper. While the efficacy of this technique has yet to be evaluated in clinical trials, monitoring the breath for such biomarkers is an attractive approach to medicine because breath analysis is the ultimate non-invasive and low-cost procedure.
