Astronomers have discovered an entire planetary system 127 light years away with at least five planets orbiting a star much like our own Sun. The scientists at the University of Geneva say the planets are from 13 to 25 times the size of Earth and covered with rock and ice.
French engineers are about to begin draining a lake that's formed under a glacier on Mont Blanc. Experts say that if it burst, the recently-discovered water pocket could flood the St Gervais valley below. The engineers planned to dig a hole into the ice and pump the water away. In 1892, water from a similar underground lake
crashed on
the valley and killed nearly 200 people.

美国一位将军表示,奥巴马总统从明年7月份开始从阿富汗撤军的计划助长了塔利班反叛分子的气焰。美国海军陆战队司令康韦将军(James Conway)表示,在该设定日期之后,塔利班分子将发现美国军队仍然不断袭击他们。
“如果你接受2011年之后美国海军仍然驻扎在阿富汗,敌人会怎么说?你们的领导在阿富汗之外,但是却试图指导国内的行动,因为他们待在那里太危险了,奥巴马应该对自己的军队怎么说?所有的军队一直都相信他说的是,明年夏天,他们所有人都将离开阿富汗。一直到秋天,我们都一如既往地打击他们。我认为,从敌人心理的角度想,这对我们将是非常好的。”
