1 60%人脑是脂肪

Yup, our brains are made up of 60 percent fat, says Dr. Michael Green, a research psychologist at Aston University.
没错，我们的脑子60%是由脂肪构成，阿斯顿大学的心理研究学家Michael Green告诉我们。

To function optimally, our brains need to maintain this level of fat. A lower amount of fat, in fact, can lead to neurological disorders. Dieters beware!
为了达到最佳运作效果，我们的大脑需要保持这个水平的脂肪量。如果脂肪量偏低可能会导致脑神经失调。节食减肥的人要注意了！

2 肠道菌会对人脑产生影响

According to new research, the composition of gut bacteria can affect brain development and adult behavior.
最新研究结果显示，肠道细菌的合成物会对脑部发育和成人行为产生一定影响。

Gut bacteria can affect autoimmune diseases like multiple sclerosis as well as developmental disorders like autism.
肠道细菌会让人类患上自身免疫病，比如多发性硬化症和自闭症这种发育紊乱。

3 人类也有定位能力

According to new research carried out by the University of Massachusetts Medical School, humans may have an internal compass that allows them to navigate across the earth without an external device.
据马萨诸塞州医学院的最新研究显示，人体内部可能也有类似指南针系统，能够让人类在不依靠外接设备的情况下也能穿越地球。

The study found that monarch butterflies have an internal sense of direction that allowed them to get from one point to another even in the absence of light by sensing the Earth's magnetic field.
有研究发现帝王蝶有方向感，可以让他们在没有光的情况下，通过磁场感应的方式，它们能精确的从某处飞到另一个地方。

Because we share a similar crypotochrome gene with monarch butterflies, it's possible that we have this magnetic sensing ability too.
因为我们和帝王蝴蝶的crypotochrome基因相似，所以我们可能也有这种定位能力。

4 3岁小朋友的脑部比成人更活跃

Three-year-old brains are two-and-a-half times more active than adult brains, says a report by the California Early Childhood mentoring program.
加利福尼亚一个早教服务项目得出结论，三岁孩子的脑部比成人的脑部要活跃2.5倍。

Because children are born with blank brains, each experience is completely new. In the first three years of his or her life, a child builds approximately 1 trillion synapses.
因为孩子的脑子里装的东西不多，任何一件事情对他来说都是新的。在孩子的头3年里，他要建立大约1兆神经突触。
