Although it would be impossible to do this on earth, you actually could do this on the moon. The moon has a cold core and it also doesn’t have any oceans or groundwater to mess things up. In addition, the moon has no atmosphere, so the tunnel would have a nice vacuum in it that [...]

The universe can be a very strange place. While groundbreaking ideas such as quantum theory, relativity and even the Earth going around the Sun might be commonly accepted now, science still continues to show that the universe contains things you might find it difficult to believe, and even more difficult to get your head around.

This tiny, near-microscopic water flea has more genes than you. In fact, this freshwater zooplankton is the first crustacean to have its genome sequenced, and its 31,000 genes crowns it the animal with the most genes so far. For those keeping count at home, the average human has about 20,000 to 25,000 genes.

This website will introduce you to some of the most important ideas in computer programming in an interactive, visual way through a guided activity. The activity is about a language for describing pictures. You will use a computer program that lets you type a sentence in the language, and shows you the picture that it [...]

随着网络的日益普及，“网络存储”这样的服务也日益深入人心，有了众多的使用者，网络服务业方面的开发商自然不会错过这个大市场。几天前，微软推出了Windows Live SkyDrive，并已经在互联网上全面进行测试，虽然容量仅仅为500MB，但是毕竟是免费的，使用的人数量极为可观。而谷歌也不是等闲之辈，SkyDrive刚刚登场就推出了自己的超大容量网络存储方案，不过收取的费用上还需要商榷。另外，苹果公司开发的.Mac平台也瞄准了“网络存储”这块大蛋糕，随时准备加入这场 “战争”。 “一个芯片制造者当然希望最快、最贵，但在桌面上这并不是未来业务的趋势。”李开复说。

编者按：印第安纳大学物理系生物复杂系统方向的博士生胡浩同学参与了一项重要的研究工作，使用计算机模拟的方法对甲型H1N1病毒的传播作出预警。他将这一信息投递到了科学松鼠会，并提供了极为详细的资料。本文为笔者在胡浩同学提供资料的基础上改写。 此外，胡浩同学所在的研究小组授权我们使用他们公布在网上的图片。 在此，我们对研究小组的全体成员致以深深的谢意。我们相信，这些科学工作者的工作将为我们抗击流行病传播的提供重要帮助。 本文刊于《新发现》 该小组的网站：http://www.gleamviz.org/ 撰文 陈朝 胡浩
