研究人员相信，烘培咖啡豆的喷香气可以安抚严重的神经-而且只是一点点喷香气就可以缓解整夜失踪眠对年夜脑造成的影响。

　　在对小白鼠年夜脑取样后，他们发现咖啡的气息，增强了关头基因的勾当，这种基因勾当可以促进体内细胞存活，而且削减焦炙。

　　A cup of freshly ground coffee is what it takes to get some people moving in the morning.

　　研究人员相信，烘培咖啡豆的喷香气可以安抚严重的神经-而且只是一点点喷香气就可以缓解整夜失踪眠对年夜脑造成的影响。

　　但一项最新的研究剖明，这种功能可能是咖啡的喷香气而不是咖啡自己发生的。

　　早晨起来，一杯新奇的研磨咖啡可以让人精神充沛。

　　But, according to a study, it may be the aroma rather than the coffee itself that does the trick.

　　Researchers believe that the aroma of roasted coffee beans can soothe frayed nerves - and that just the whiff could be enough to reverse the effects of a poor nights sleep on the brain.

　　Aroma: Just smelling coffee can help cure tiredness better than drinking a cup

　　喷香气: 仅仅闻咖啡比喝一杯咖啡更能辅佐缓解委靡。

　　They said that chemicals extracted from coffee and pumped into the air may one day be used as a way of reviving tired people.

　　After taking samples of the rats brains, they found that the smell of coffee boosted the activity of key genes that promote cell survival in the body and reduce anxiety, New Scientist magazine reports today.

　　他们说，迟早有一天可以经由过程提取咖啡中的化学物质并释放到空气中，来缓解人们的委靡。

　　Scientists in Tsukuba, Japan, kept 16 laboratory rats awake for 24 hours, by keeping them in a cage filled with an inch of water, then exposed half of them to the smell of roasted coffee.

　　日本筑波的科学家们把16只小白鼠放到有1英寸深的水的笼子里，这样保证它们24小时不睡觉。然后，将一半的老鼠放在烘培咖啡的喷香气中。

　　在对小白鼠年夜脑取样后，他们发现咖啡的气息，增强了关头基因的勾当，这种基因勾当可以促进体内细胞存活，而且削减焦炙。

　　Professor Yoshinori Masuo, who led the study in Tsukuba, Japan, said that when people drink coffee to stay up all night, just the smell of the coffee could alleviate some of the stress caused by sleeplessness.

　　率领日本筑波研究团队的益男教授说，当人们为了熬夜而喝咖啡时，仅仅是咖啡的味道就会减轻由不睡觉而发生的压力。

　　He added: Is it better for us to smell coffee bean aroma than to drink coffee, or would any other food-related odour produce similar effects? Further studies are needed.

　　他填补说：闻咖啡豆的气息要比喝咖啡更好。可是否其他食物的气息会发生近似效应呢?
