评：

看了这篇文章，心情顿时变得复杂起来。没有人敢于坦白社会当前的境遇与自己无关，其实正是有了每一个人的行为才有了今天的社会。这篇文章乍一看会容易让人觉得是满腹牢骚，甚至怀疑作者是个愤青。其实，这年头做一个愤青谈何容易？！其实，经济的繁荣固然重要，但对于一个民族，一个国家来讲，精髓文化和理想的缺失以及核心价值观的畸形发展才是这个社会最要命的事情。曾几何时，我们面对那些狰狞的现实感叹，然而，当尘埃充斥于周遭让人无法呼吸的时候，我们是否会怀疑，亦或有力怀疑，这是一个无药可救的病态社会？其实，社会不会灭亡，但有些形态被沦为它的陪葬品却将是不争的事实，到时候，我相信，很多人会无动于衷。民生多艰，怎何止50个异常现象呢？！各种乱象犹如诱人的大麻，吸引着人们兴趣，侵噬着人们的躯体，当行尸走肉变得魂不附体，当美好于一夜之间蒸发，留下的是一塌糊涂。

不要感到“唱衰中国”的声音充满‘怪诞’。我一直惊叹，国外机构竟将问题看得甚至比国人都透彻，仅仅是当局者迷么？无论如何，已经不容乐观了。国人爱面子、好吹嘘、图虚荣、喜欢将真理憋在心里直至把那当成垃圾。这篇文章估计会让人们警醒，不过不好说。其实，每个人在感叹“无能无力”的时候真得不如做点什么，或者说点什么。有钱出钱，有力出力吧！

Human genome at ten: Science after the sequence

The completion of the draft human genome sequence was announced ten years ago. Nature 's survey of life scientists reveals that biology will never be the same again. Declan Butler reports.

Declan Butler

"With this profound new knowledge, humankind is on the verge of gaining immense, new power to heal. It will revolutionize the diagnosis, prevention and treatment of most, if not all, human diseases." So declared then US President Bill Clinton in the East Room of the White House on 26 June 2000, at an event held to hail the completion of the first draft assemblies of the human genome sequence by two fierce rivals, the publicly funded international Human Genome Project and its private-sector competitor Celera Genomics of Rockville, Maryland (see Nature 405, 983–984; 2000).

Networks have become a key approach to understanding systems of interacting objects, unifying the study of diverse phenomena including biological organisms and human society1, 2, 3. One crucial step when studying the structure and dynamics of networks is to identify communities4, 5: groups of related nodes that correspond to functional subunits such as protein complexes6, 7 or social spheres8, 9, 10. Communities in networks often overlap9, 10 such that nodes simultaneously belong to several groups. Meanwhile, many networks are known to possess hierarchical organization, where communities are recursively grouped into a hierarchical structure11, 12, 13. However, the fact that many real networks have communities with pervasive overlap, where each and every node belongs to more tha

Science economics: What science is really worth

Colin Macilwain

Spending on science is one of the best ways to generate jobs and economic growth, say research advocates. But as Colin Macilwain reports, the evidence behind such claims is patchy.

President Barack Obama says it. Francis Collins, director of the US National Institutes of Health (NIH), says it. University and research leaders elsewhere are saying it, too. The number one current rationale for extra research investment is that it will generate badly needed economic growth.

Conservation biology: When an infection turns lethal

一天，和Joan（我在美国的导师）讨论问题，她突然问我“homolog”与“ortholog”有什么区别，我一听觉得是个很简单的问题，但是支支吾吾半天也只是解释个了大概，仅仅停留在自己所知道的表层上面，而且很不专业。但当时我们三个人讨论了一下，似乎是弄懂了。桌子上信手涂鸦的草纸堆了一沓了，很不整洁，我今天打算把它们扔进垃圾桶，却又饶有兴趣地一张张地翻看起来，过去一段时间的工作场景突然像放电影似的从脑海浮现。我忽然从一堆潦草的字句间看到了当时Joan写的这几个单词，决定还是把书面解释弄清楚一些。

大家请看下文：

１. Homolog: A gene related to a second gene by descent from a common ancestral DNA sequence. The term "homolog" may apply to the relationship between genes separated by speciation (ortholog), OR to the relationship betwen genes originating via genetic duplication (see paralog).

关于“基因”的定义，各位有兴趣的看一下吧，详情见附件。另附一张有用的图图。
