You can do that? A massive correction in Nature, but no retraction
This past April, Amparo Acker-Palmer and colleagues published a study in
Nature, “Ephrin Bs are essential components of the Reelin pathway to
regulate neuronal migration.” Within a day of its publication, Nature
readers were raising questions about many of its figures. They started like

amazing paper in JBC and crappy ir-reproducible paper in NCS (hell, I know a
lab's NCS papers are mostly unreliable at best and can only be reproduced
by the 1st author, muhaha). If a school can not distinguish what research
is good and the likelihood of the subject getting funded or not, the school
got more problem than just hiring people. |

胡编瞎说),有些可能值得我们去深究一下。
比方说中医对食物分类成热凉什么的。这个目前挺难用现在的科学来解释的,如果是方

子以及氨基酸分子才吸收的,怎么可能有区别呢,一定是胡说八道!
但是那些说法偏偏还就挺reproducible的,比方说一般人在大夏天吃了个什么上火的东
西,真的就容易流鼻血的。而我觉得对于我们这些研究者来说,凡是可以reproducible
的却不能被当前理论解释的现象都应该引起我们的好奇心。因为里面可能潜伏有我们
当前的理论没有覆盖到的东西。当然,我觉得我们应该在对于中医里面描述的现象留心
理会,而不是盲目相信或者照搬中医里面的“理论”。
再发散一下,上面有人说“人中黄”不是大粪(而是用大粪泡过的甘草)所以和菌群平

网上说《本草备要》里面对“人中黄”的疗效的描述是这样的:

缺点是维修比较贵,由于典型的double beam设计,旧仪器chopper元件的故障率很高,

A species becomes extinct when the last existing member of that species dies
. Extinction therefore becomes a certainty when there are no surviving
individuals that are able to reproduce and create a new generation.
好,我问你,恐龙的最后一个个体死了?恐龙就没有最后一个个体,如果你对John
Ostrom的理论没异议的话。或者你认为wiki的这段话不符合你这个文科生的用词习惯或
是修辞方法? |

w****j 发帖数: 5581 | 46 关键字reproduce 和new generation你确定看见了?
你真的认为John Ostrom在胡说八道?Yes or No? |

D***r 发帖数: 7511 | 47 reproduce就是繁殖的意思而已
人家说的是物种内
他加上这句话的意思是说,假如中国只剩三头大熊猫了
俩公的,一个母的但是没卵巢,那么大熊猫的灭绝就becomes uncerntainty
虽然还没有灭绝
或者全世界的马都发疯了跟驴杂交
也是注定灭绝了 |

首先,生命未必非要以碳水化合物的形式存在,任何可以reproduce的负熵消耗体都是
生命,所以生命可以以很多人类可以想象或者无法想像的形式存在,因此完全可以存在
于很多人类认为环境极端严苛的星体上。
其次,由简单生命体演化出智慧生命是小概率事件。
再次,智慧生命未必热衷于建造巨型工程。
再再次,以人类无法想像的形式存在的智慧生物制造的巨型工程人类依然未必能够想象。 |

讨论问题收获很多,乐在其中。Reynold当初写的1001夜就特别好,我还专门为此淘旧
书买了一套Burton翻译的带插图的Heritage Press版。虎鲸指点下我还搞了本西班牙史
,虽然惭愧的是到现在都没抽功夫看一遍。这是我的乐趣。对于你来说,看来打脸是你
的乐趣。虽然我无意质疑你的喜好,但是也不打算按照你的路数来。我只讲我认为是对
的事情,讨论问题而已。以上。
好了,回到正题。首先要道个歉。你既然认为我转述Peter Jackson十分不堪,我也就
核对了一下。我基本上对原文稍微rephrase了一下,不过漏掉了这样一句话,大概会引
起争议。不翻译,直接原文照搬:

later inserts material gleaned from a different (but surely Mongol) source.
