在这个充满安全、甚至纯洁的世界,吸血鬼故事,《通道》一书的作者——贾斯汀·克罗宁(Justin Cronin),正在积聚我们对这种嗜血狂魔的恐惧。
In a world riddled with safe, even chaste, vampire stories, author Justin Cronin's The Passage is restoring our fears of bloodsuckers.
现在我们获得了第一个离子通道的分子结构,提供了对三维结构离子通道孔的了解。
We now have obtained the first molecular structure of an ion channel, providing us with a three-dimensional understanding of the ion channel pore.
不过,考虑到现在我们的信息通道已经变得相当分散,我对这种做法没有多少信心。
But I find it hard to place much faith in that approach given how fragmented our information channels have become.
And all ion channels are selective for a single type of ion, and we can think about how that selectivity takes place, and that's where this idea of atomic radius is going to become very important.
所有的离子通道都是仅对某一种离子具有选择性的,而我们可以来想一想这种选择性是如何发生的,这也就是原子半径这个概念将会变得,非常重要的地方。
