在16世纪特诺奇蒂特兰的阿兹特克城,献祭的人类受害者头骨会被穿在木柱上,并在一个纪念用的架子上展示。墨西哥国家人类学与历史学研究所的考古学家最近在墨西哥城市中心的发掘工作中,发现了这个纪念架的残骸,以及2个附带的头骨塔。

In the Aztec city of Tenochtitlan in the 16th century, the skulls of human sacrificial victims were slipped onto wooden posts and displayed on a monumental rack. Archaeologists at Mexico's National Institute of Anthropology and History discovered the remains of the rack and two accompanying skull towers during recent excavations in downtown Mexico City.

封面插图展示的是不断增长的人口正在以越来越快的速度改变我们的地球,由此导致了气候变化、资源减少及生物多样性的丧失。如果继续目前的状况而不加抑制,很可能会危及我们自己及其他物种的福祉,但是想要改变行进的方向就需要面对艰难的抉择。在“明天的地球”特别系列文章中,我们探索了通往更加可持续未来的道路。

Growing human populations are transforming our planet at an increasing rate, leading to climatic changes, diminished resources, and loss of biodiversity. Continuing on the current path is likely to endanger our own well-being and that of other species, but changing course involves tough choices. In the Tomorrow's Earth special series, we explore paths to a more sustainable future.

当医师对药物批准建议进行投票后会收到制药公司支付的费用,对此进行的一项分析表明,美国食品和药物管理局(FDA)需要考虑未来的回报前景是否会影响其顾问小组的工作。同时该调查还指出,对于那些顾问来说,FDA可能已经错失了更多传统的利益冲突。本期中另有一篇文章则是针对FDA员工的“旋转门”问题。

An analysis of pharmaceutical payments to physicians after they voted on drug approval recommendations suggests that the Food and Drug Administration (FDA) needs to consider whether prospects of future rewards could influence its advisory panels. The investigation also indicates that the FDA may have missed more traditional conflicts of interest for those advisers. Another story looks at revolving-door concerns for FDA staff.

封面上展示的是通过艺术手法描绘的南极冰立方中微子天文台。单个球形数字光学模块(DOM)直径约为35厘米,它们被放置于冰层深处2.5千米处。超过5 000个DOM组成了1立方千米的探测器,重量超过10亿吨。当高能中微子与冰相互作用时,这些DOM就会探测到其产生的微弱闪光。

Artist's impression of the IceCube Neutrino Observatory in Antarctica. Spherical digital optical modules (DOMs), each about 35 cm in diameter, are positioned up to 2.5 km deep in the ice. More than 5 000 DOMs make up a cubic-kilometer detector weighing more than a billion tons. The DOMs detect the faint flash of light created when a high-energy neutrino interacts with the ice.
