Fruit Flies Think Before They Act
果蝇先想后行动
A fruit fly’s lifespan is usually less than 60 days. It’s not much time for them to develop advanced mental capabilities. But a study from Oxford University shows that fruit flies actually think before they act. They even take more time when making difficult decisions， although they obviously can’t take more than 60 days.
果蝇的寿命通常不超过60天，对它们来说要发展高级智能这点时间并不够。但是牛津大学的一项研究发现果蝇通常会先想后行动。它们甚至会花很多时间去做艰难的抉择，尽管很明显，它们思考的时间不能超过60天。
Asian Elephants Comfort Others in Distress
亚洲象会安慰情绪低落的同伴
Consolation is rarely seen in animals， possibly because it may require empathy. But a study published in the journal Peer J shows that Asian elephants will now join the select group of animals scientifically shown to display this behavior. Until now， the group has only included great apes， ravens and certain other corvids， and canines.
安慰这一行为在动物中很少见，这可能是因为安慰需要情感共鸣。但是一项发布在Peer J杂志上的研究显示，科学证实亚洲象已加入了能表现安慰行为的精英动物团体。直到现在，会表现出这一行为的动物仅仅有类人猿、乌鸦以及其他一些鸦科动物和犬齿类动物。
Rats Have Memories Like Computers
老鼠有像计算机一样的记忆功能
Like computers， rats have short-term， random-access memories that store information used in ongoing processes. Humans and crows also have these working memories.
像计算机一样，老鼠也有短期的随机存取的记忆功能。人和乌鸦也有这种记忆功能。
Zebra Finches Fake It to Make It
斑胸草雀善于伪装
Unlike male song sparrows， zebra finches aren’t giving their potential mates the opportunity to judge. If a zebra finch is sick， it will fake being healthy in front of other zebra finches， especially if there’s a chance to mate. No word on what else they’re faking.
和雄性歌带鹀不一样，斑胸草雀不会给它们的潜在配偶评判的机会。如果一只斑胸草雀生病了，它会在其同类面前装作很健康的样子，在它有机会结交配偶的情况下尤其如此。很难说，它们还有什么伪装。
