《科学》对传说中的STAP细胞论文的三名评审专家意见,过去一直被雪藏,今天终于
被曝光。专家对这一研究的评价不高,认为非常全面的描述性研究,如果结果确定,可
能导致发育生物学大厦的颠覆,其实是不相信这种研究结论。因为没有当时的投稿件,
所以没有办法对这些评价进行更深入分析。不过这些资料显然都在某个地方,只是拥有
的人不愿意拿出来。
Retraction Watch readers are of course familiarwith the STAP stem cell saga,
which was punctuated by tragedy last month whenone of the authors of the
two now-retracted papers in Nature committed suicide.

不过话说回来,为什么高等动物发展出parental imprinting这个机制? |

G******n 发帖数: 289 | 8 parental imprinting是为了保证母体或者父体基因传递。父方肯定希望自己的基因传
下去,所以要在众多受精卵中快去生长。而对于母方,如果所有受精卵后代都成活,那

所有受精卵胚胎平等生长。 |

imprinting最早可追溯到什么物种?
高等哺乳动物一胎都是同一个父亲吗?或者可以同母异父? |

Using DBI inflation as an example, we demonstrate that the detailed geometry
of warped compactification can leave an imprint on the cosmic microwave
background (CMB). We compute CMB observables for DBI inflation in a generic
class of warped throats and find that the results (such as the sign of the
tilt of the scalar perturbations and its running) depend sensitively on the
precise shape of the warp factor. In particular, we analyze the warped |
