2012-05-04 雅各布港冰川（Jakobshavn Isbr）是格陵兰冰原上速度最快的注出冰川之一，每天从冰川崩裂下来的冰块、冰山形成了封面上这种独特的冰峡湾景观。冰峰宽约5千米，前端高出水面约80米，并延伸至水下超过600米。近期研究表明，格陵兰冰川的速度在不断加快。
A jumble of icebergs forms in front of the heavily crevassed calving front of Jakobshavn Isbr, one of the fastest outlet glaciers draining the Greenland Ice Sheet. The～5-kilometer-wide ice front rises ～80 meters out of the water and extends more than 600 meters underwater. Recent research shows that the speeds of Greenland glaciers are increasing.

封面上是通过NASA曙光号宇宙飞船拍摄到的图片与地形数据整合出的增强色彩图像，为人们展示了在小行星灶神星上的“雪人”环形山。跨度约为60千米的玛西亚环形山（图片底部）是灶神星上最年轻的大环形山之一，它有一个小小的中央峰，并且在山体上有深色和浅色的条纹。文中有6篇系列报道详尽描述了相关内容。
Enhanced-color view of the "Snowman" craters( Marcia,Calpurnia, an d Minucia) on the asteroid Vesta generated by combining imaging and topography data from NASA’s Dawn spacecraft. The 60-kilometer-wide Marcia crater(at bottom) is one of the youngest large craters on Vesta with a small central peak, as well as light and dark streaks on its walls.

现如今，我们对于人与人之间的冲突屡见不鲜，例如2006年8月13日发生在黎巴嫩贝鲁特的爆炸事件，始作俑者就是以色列国防军，封面图片就拍摄于爆炸现场。文中的特别章节，通过检视冲突的来源、其发展的历史轨迹，以及其在现代的表现形式，集中讨论了关于“人际冲突”这个论题。同时，我们也分析了人类自身维系和平的能力，并且审视了那些远离战争的社会是怎样的。封面图片只是视觉图片，并不带有任何政治内容或背景。
We are all too familiar with human conflict, such as this bombing on 13 August 2006 in Beirut, Lebanon, by the Israel Defense Forces. In the special section on Human Conflict, we examine the origins of conflict, trace its path through history, and consider its modern manifestations. We also analyze our innate ability to foster peace and look at societies that eschew war. This cover was chosen for visual imagery and not for any political message or endorsement.

封面上是通过艺术渲染的一种电子设备——马约拉纳费米子虚拟主机。图中半导体纳米线（柱状构造）直径为100纳米，它位于由多个金属条构成的门结构顶部。这条纳米线的顶部与1个金制的电极相连，底部与1个超导电极（图中蓝色部分）相连。
Artist’s rendering of an electronic device hosting Majorana fermions. The semiconducting nanowire (cylindrical structure) has a diameter of 100 nanometers and lies atop a gate structure consisting of many metallic stripes. The nanowire is contacted at the top with a gold electrode and at the bottom with a superconducting electrode (shown in blue).
