类橡胶印刷电路板的实现具有挑战性,是由于电路线路必须具有高导电性、可拉伸性和应变不敏感等特性。研究人员开发了一种利用声波在聚合物中结合2种不同大小液态金属颗粒的方法。这就产生了类似橡胶的印刷液态金属线路,便于组装系统级的可拉伸电子产品。

Rubber-like printed circuit boards are challenging to realize because circuit lines must be highly conductive, stretchable, and strain insensitive. Researchers have developed a process to assemble two different sizes of liquid metal particles in polymers using acoustic waves. This results in rubber-like printed liquid metal circuit lines for the facile assembly of system-level stretchable electronics.

封面展示的是1959年9月9日在法国巴黎凡尔赛展览中心举行的第21届广播电视展上,一台便携式收音机被托在手中的画面。75年前晶体管的发明刺激了影响通信、计算、控制系统、仪器仪表和其他技术的创新。现如今,新的晶体管技术在许多领域持续发展进步。

A hand holds a portable radio originally presented at the 21st Radio and Television Show at the Porte de Versailles Exhibition Center in Paris, France, on 9 September 1959. The invention of transistors 75 years ago spurred innovations that affected communication, computation, control systems, instrumentation, and other technologies. Today, the development of new transistor technologies continues on many fronts.

封面图展示的是唤起细胞工程强大而重要的潜力。研究人员能够通过改变细胞调节回路从而设计改良细胞,以推进基础科学并且改进治疗方法。现在,研究人员可以修改各种细胞类型或细胞组,使其成为推动实验研究或者执行诊断和治疗功能的智能代理。

The drawing evokes the powerful and momentous potential of cell engineering. The ability to alter cellular regulatory circuitry enables researchers to design modified cells to advance basic science and improve therapies. Investigators can now modify various cell types or groups of cells to operate as smart agents that facilitate experimentation or execute diagnostic or therapeutic functions.

封面图展示的是1张长时间曝光照片,拍摄的是在一个月明的夜晚,黄石国家公园下间歇泉盆地的漏壶间歇泉正在喷发。黄石国家公园的间歇泉和其他热液地貌是由地球上地壳岩浆库的热量提供燃料的。新的黄石公园地震成像图使人们对地下岩浆的体积和分布有了进一步的了解。

A long-exposure photograph shows the Clepsydra Geyser erupting on a moonlit night in Yellowstone National Park’s Lower Geyser Basin. Geysers and other hydrothermal features in Yellowstone National Park are fueled by heat from a magma reservoir in Earth’s upper crust. New seismic imaging of Yellowstone has provided further insight into the volume and distribution of magma in the subsurface.
