Just smelling the aroma of coffee is enough to change the activity of several genes in rats, researchers report this week in The Journal of Agricultural and Food Chemistry. The affected genes appear to help the animals deal with resistance to the stresses caused by sleep deprivation.

Project neuroscientist Yoshinori Masuo of Japan's National Institute of Advanced Industrial Science and Technology talks about whether we should just sniff our morning coffee instead of drinking it.
