+ - 3M uses quantum dots to make cell phones more colorful->

Submitted by Gunnery Sgt. Hartman
Gunnery Sgt. Hartman (221748) writes ""3M announced today it is in the final stages of scale-up for its new 3M Quantum Dot Enhancement Film (QDEF). The new film allows up to 50 percent more color than current levels in liquid crystal display (LCD) devices. 3M has teamed with Nanosys, Inc., to produce the 3M QDEF solution specifically to deliver more color, and to make devices such as smart phones, tablets and televisions, lighter, brighter and more energy efficient.""

+ - For women nothing's like the smell of men's sweat

gollum123 writes "From CNN, Researchers at the University of California at Berkeley said women who sniffed a chemical found in male sweat experienced elevated levels of an important hormone, along with higher sexual arousal, faster heart rate and other effects ( http://www.cnn.com/2007/HEALTH/02/08/men.sweat.reu t/index.html ). They said the study, published this week in the Journal of Neuroscience, represents the first direct evidence that people secrete a scent that influences the hormones of the opposite sex. The researchers measured levels of the hormone cortisol in the saliva of 48 female undergraduates at Berkeley, average age of about 21, after the women took 20 sniffs from a jar of androstadienone. Cortisol levels in the women who smelled androstadienone shot up within roughly 15 minutes and stayed elevated for up to an hour. Consistent with previous research, the women also reported improved mood, higher sexual arousal, and had increased blood pressure, heart rate and breathing. The study did not determine whether the increase in cortisol levels triggered mood or arousal changes or whether those changes themselves caused the cortisol elevation."
