A peer-reviewed study published Thursday suggests that ethanol -- or alcohol -- can help plants survive in times of drought. The researchers in Japan found that adding ethanol to the soil can protect plants from dying in a drought, even for as long as two weeks without water. The researchers said that ethanol was a "useful and simple" way to increase food production all over the world in times of drought or water scarcity.

周四发表的一项经同行评议的研究表明，乙醇——或酒精——可以帮助植物在干旱时期生存。日本的研究人员发现，在土壤中加入乙醇可以保护植物在干旱中不致死亡，甚至在长达两周的无水状态下也可以。研究人员说，在干旱或缺水的时候，乙醇是一种“有用而简单”的方法，可以增加全世界的粮食产量。
