In this new view, air again rises at the equator, but falls in the subtropics, making the first cell. The second cell consists of air rising in the middle latitudes—about 30 to 60 degrees north and south—and then falling again near the poles. The study says that this second cell of rising air accounts for temperatures, winds and moisture levels in the mid-latitudes. Water vapor is a major driver of weather events in the tropics. Turns out it may be just as important for weather—and climate—farther north and south.

The research team is also working towards making a STAIR cell prototype suited, in the first instance, for small applications, such as mobile phones or MP3 players.
研究团队还在努力制作合适的STAIR电池原型,起初用于一些小型电器上,比如移动电话和MP3播放器。
So, when the right signal is received, the right T-cell finds your host cell with a foreign virus in it, the first thing that happens is that this T-cell becomes activated and it starts reproducing, making more copies of itself.
所以 当接收到正确的信号,恰当的T细胞寻觅到,感染外源病毒的细胞时,首先发生的是,T细胞被激活并开始增殖,制造更多自身拷贝
