Starbucks Is Gonna Love This

The New York Times reports on research into smelling coffee, rather than drinking it. In the study, "Han-Seok Seo of Seoul National University and colleagues exposed stressed-out rats that had been deprived of sleep to coffee bean aroma and then evaluated the effects by performing genetic and protein analyses on brain tissue." The findings: the aroma alone was enough to cause significant gene and protein expression changes -- and perhaps enough to keep you awake through that next mind-numbing department meeting.

On the bright side, the scent of coffee will never burn a hole in your stomach.
