作者:Michael Brooks,原文 译者:Robot ——这是你从未见过的人脑 当马乔里•泰勒(Marjorie Taylor)第一次看到大脑图像时,她简直就被迷住了。那些鲜艳的粉色和蓝色,精致的细节设计,好像就在对她说话。“没办法,我看它们的眼神完全就是一个手工布艺者的眼神,”俄勒冈大学的心理学家泰勒这样说,“我觉得大脑皮层的摺皱要是用天鹅绒来做就太棒了。”
原文,译者,山寨盲流。 一头名叫Metana的牛是阿根廷农业技术研究所一项实验的主角,旨在减少牛肠胃排放的甲烷。甲烷促进了引发全球变暖的温室效应(图片:Redux / Eyevine)(译者:既然是甲烷研究的牛就应该有个甲烷的名字,就叫萌萌吧。) 牛,绵羊和山羊表面上只是人类的盘中餐,可暗地里却在影响气候。它们在绵延起伏的牧场悠闲地游荡,一边咀嚼着反刍的食物,浑然不知自己的饱嗝(还有一小部分排放来自放屁)正在使地球变暖,不要说汽车飞机,有可能连发电厂都不如它们的危害大。

原文链接 Cutting the jellyfish rings with scissors was impossibly slow; we could not produce the amount of aequorin that we needed using this technique. This problem was solved primarily by Dr. Johnson. He constructed the first model of a jellyfish-cutting machine in the summer of 1967; it was essentially a strip of wire screen that [...]
原文链接 In 1962, using the methods that had worked in the previous year, we obtained an additional amount of aequorin and began to study various aspects of the molecule, including its application in the measurement of calcium ions. We also wanted to know the mechanism of the luminescence reaction and the structure of the light-emitting [...]

原文链接 Why two eyes are better than one. By Oliver Sacks When Galen, in the second century, and Leonardo, thirteen centuries later, observed that the images received by the two eyes were slightly different, neither of them appreciated the full significance of these differences. It was not until the early eighteen-thirties that the English scientist [...]
