Most of us are familiar with the concept of six degrees of separation——the idea is that anyone in the planet can be connected to anyone else in just six steps.But is there actually any science to back up this commonly cited theory? If you just take a look at the following numbers,...

Another tip is to remind yourself that you are unique. Everyone has their own talents—you may be good at painting or playing the piano, so take pride in things you do well instead of worrying about things you cannot change. Focusing on your strengths helps you build your confidence. ...
Organisms are linked by lines of descent from common ancestry. 所有生物都拥有共同的祖先,这里主要是讲物种之间的相似性。 Organisms share many conserved core processes and features that evolved and are widely distributed among organisms today. 按照分类学说,所有的生物可以分为三域:古细菌域(Archaea)、真细...
knowledge of the Australian representatives of a group of organisms has led to a radical change being effected in the basic classification of the same group in other faunal zones. The usual arrangement of the various genera into sub- families on the basis of the position of the ocelli is ...
accounts for the serum cross-reactivity, in particular of IgE, between these organisms[66–69]. The fucose at the 3-position of the distal GlcNAc has not been identified in other species so far, and is not detected in L3 larvae, showing that this unusual modification is stage-specific[70]...
The phosphatidylinositol 3-kinase (PI3K) signaling path- way is a widely expressed component of growth factor signal- ing in diverse organisms and cell types.54 Mutations that en- hance PI3K signaling are common in cancer, and include mutations in the p110␣ catalytic subunit of the PI3K ...
due to the interplay between impacts of Pleistocene climate shifts and contemporary hydrographical barriers. These factors markedly shaped the distribution of marine organisms and their genetic makeup. The present study is part of an ongoing effort to understand the phylogeography and evolutionary history...
