Inexpensive Detector Sees The Invisible, In Color May 24, 2006
An inexpensive detector developed by a NASA-led team can now see invisible infrared light in a range of "colors," or wavelengths. The detector, called a Quantum Well Infrared Photodetector (QWIP) array, was the world’s largest (one million-pixel) infrared array when the project was announced in March 2003. It was a low-cost alternative to conventional infrared detector technology for a wide range of scientific and commercial applications.

Light-to-moderate Prenatal Alcohol Exposure Can Lead To Cognitive Deficits 10 Years Later
Although deficits in measures of intelligence are well documented among children exposed to high amounts of alcohol during pregnancy, deficits among children prenatally exposed to low-to-moderate amounts of alcohol are much less understood. A study in the June issue of Alcoholism: Clinical & Experimental Research has found that even light to moderate drinking — especially during the second trimester — is associated with lower IQs in offspring at 10 years of age.
