The last good news was that smart people drink more coffee and stay smart later in life. Tea drinkers do better than those who don't drink either beverage, but coffee was the best smarts-maintainer. I think it has to do with the previously researched fact that caffeine inhibits amyloid deposition in the brain--that's what causes Alzheimers.
But there's MORE. This study indicates that coffee actually lowers the risk of pharyngeal, esophageal and oral cancers. At least in Japan it does. The association appears to apply without regard for smoking status or gender.
