It’s Good to Know: Your Morning Whiff of Joe

Coffee is part of the morning wake-up ritual for millions of people worldwide. But recent research by South Korean scientists indicates that you might not have to drink it to get that "pick-me-up" effect. When the researchers exposed sleep-deprived rats to coffee aromas, they found that the activity of some genes in their brains changed, reducing the effects of sleeplessness.

No human trials are planned. But next time you’re at Starbucks, why not skip the latte and simply inhale deeply near the counter? (Report back if you notice any energizing effects.)
