Something like that. When we're craving things like food, water, or drugs, or anticipating getting them, two areas deep within the brain, the ventral tegmental area and caudate nucleus, are active.

差不多吧。当我们想要像食物、水和毒品时，或是正在"享用"它们的时候，我们的左右半边大脑深层部分，中脑腹测被盖区和神经末梢都活动起来了。

UGC 5101 is a peculiar galaxy with a single nucleus contained within an unstructured main body that suggests a recent interaction and merger. UGC 5101 is thought to contain an active galactic nucleus an extremely bright, compact core - buried deep in the gas and dust.

ugc5101是一个仅有单独一个星核的特殊星系，并且没有结构性的主体，这一切都说明他是最近才发生接触并碰撞的。ugc4101被认为包含一个活跃的星系核，其非常明亮，非藏紧密—在其深处埋藏着氢气核尘埃。

In the core of the larger spiral structure of NGC 1300, the nucleus shows its own extraordinary and distinct "grand-design" spiral structure that is about 3,300 light-years long. Only galaxies with large-scale bars appear to have these grand-design inner disks — a spiral within a spiral. Models suggest that the gas in a bar can be funneled inwards, and then spiral into the center through the grand-design disk, where it can potentially fuel a central black holes. NGC 1300 is not known to have an active nucleus, however, indicating either that there is no black hole, or that it is not accreting matter.

星系演化除了像两个星系相撞那样的剧烈作用之外，还有自己内部很慢的演化，因为一个星系总会有一些引力不稳定，如上图中的NGC1300，它是一个棒旋星系，这种bar结构导致的引力不完全对称会驱使很多气体和尘埃损失角动量往里面落，我们可以清楚的看到dust lanes，有点像黑洞的吸积，但这个星系是个非活动星系，目前还没有黑洞存在的明确证据，but我相信肯定是有的，没有比在星系中心放一个黑洞再完美不过的事情了，或许这些下落的dust lanes是黑洞发光的开始呢。

流感病毒M2蛋白5个关键位点氨基酸残基（第26、27、30、31和34位）中的任何一个发生突变会导致抗流感病毒药物中金刚烷胺抗药性的产生。

They were within fifteen miles of Monte Cristo when the sun began to set behind Corsica, whose mountains appeared against the sky, showing their rugged peaks in bold relief; this mass of rock, like the giant Adamastor, rose dead ahead, a formidable barrier, and intercepting the light that gilded its massive peaks so that the voyagers were in shadow.

当他们离基督山只有十五哩的时候，太阳开始沉落到科西嘉的后面，科西嘉的群山在天空的衬托下划出明晰轮廓，雄劲地呈现出峥嵘的山峰。这座大岩山象巨人亚达麦斯脱似的气势汹汹地俯视着小船，遮住了太阳，而太阳又染红了它的山巅。
